Öğe Apical extrusion of intracanal debris and irrigant following use of various instrumentation techniques(MOSBY-ELSEVIER, 2008) Kustarci, Alper; Akpinar, Kerem Engin; Er, KuersatObjective. The purpose of this study was to compare in vitro the amount of debris and irrigant extruded apically from extracted teeth, using manual technique and crowndown pressureless technique by K3, RaCe, and FlexMaster instruments. Study design. Sixty human single-rooted mandibular premolar teeth were randomly assigned to 4 groups, 15 teeth each. The teeth in 4 groups were instrumented until the working length with RaCe, K3, FlexMaster, and K-type stainless steel instruments respectively. Debris and irrigant extruded from the apical foramen were collected into vials and the amounts were determined. The data obtained were analyzed using Kruskal-Wallis 1-way analysis of variance and Mann-Whitney U tests, with alpha=0.05 as the level for statistical significance. Results. No statistically significant difference was observed among the groups in terms of debris extrusion ( P >.05). On the other hand, a statistically significant difference was observed between K3 and manual technique groups in terms of irrigant extrusion ( P >.05). The difference between other groups was not statistically significant ( P >.05). Conclusion. Based on the results, all instrumentation techniques produced extruded debris and irrigant; however, the engine-driven nickel-titanium systems were associated with less apical extrusion and irrigant.Öğe Bactericidal Effect of Different Power Parameters of Potassium-Titanylphosphate Laser on Enterococcus faecalis(AVES, 2018) Arslan, Dilara; Kustarci, Alper; Celik, CemObjective: The objective of this study was to evaluate the antimicrobial activity of different power settings of potassium-titanylphosphate (KTP) laser in experimentally infected root canals. Methods: A total of 119 freshly extracted human single-rooted teeth with mature apices were selected for study. After preparation and sterilization, the specimens were inoculated with 15 mu L Enterococcus faecalis for 24 hours at 37 degrees C. The contaminated roots were divided into five experimental groups (1W, 1.5W, 2W, 3W, and 4W KTP laser), one negative control [sodium hypoclorite (NaOCl)] group, and one positive control [sterile saline (SF)] group of 17 teeth each. Before and after applications in the groups, samples retrieved with sterile paper points from the root canal were transferred to tubes containing 5 mL of the brain heart infusion broth. Next, 10 mu L of these suspensions were placed at two different sides of the blood agar medium. Bacterial reduction was counted according to the colony-forming units and data were statistically analyzed using the Kruskal-Wallis and Tukey's tests. Results: The maximum decrease occurred in the 2.5% NaOCl (100%+/- 0.00%) group. This decrease was followed by decreases in the following KTP laser groups: 4W (94.26%), 3W (87.98%), 2W (77.43%), SF (68.80%), 1.5W (65.89%), and 1W (52.08%). Statistically, the difference between the 1W KTP laser group and all groups and the difference between the 2.5% NaOCl group and all groups, except the 4W KTP laser group, were found to be significant (p<0.05). Conclusion: High-power KTP laser irradiation showed efficient antibacterial activity against E. faecalis.Öğe Bactericidal effect of KTP laser irradiation against Enterococcus faecalis compared with gaseous ozone: an ex vivo study(MOSBY-ELSEVIER, 2009) Kustarci, Alper; Suemer, Zeynep; Altunbas, Demet; Kosum, SerpilObjective. The objective of this study was to evaluate the antimicrobial activity of potassium-titanyl-phosphate (KTP) laser and gaseous ozone in experimentally infected root canals. Study design. Eighty single-rooted teeth with straight canals were selected. After preparation and sterilization, the specimens were inoculated with 10 mu L Enterococcus faecalis for 24 hours at 37 degrees C. The contaminated roots were divided into 2 experimental groups, 1 negative control group, and 1 positive control group of 20 teeth each: Group 1, KTP laser group; Group 2, gaseous ozone group; Group 3, sodium hypochlorite group (NaOCl) (negative control); and Group 4, saline group (positive control). Sterile paper points used to sample bacteria from the root canals were transferred to tubes containing 5 mL of brain heart infusion broth. Then 10-mu L suspension was inoculated onto blood agar plates. The colonies of bacteria were counted and data were analyzed statistically using Kruskal-Wallis 1-way analysis of variance and Mann-Whitney U tests. Results. There were statistically significant differences between all groups (P < .05). The saline group had the highest number of remaining microorganisms. Complete sterilization was achieved in the 2.5% NaOCl group. The KTP laser and gaseous ozone did not completely sterilize the root canals. Conclusion. Both KTP laser and gaseous ozone have a significant antibacterial effect on infected root canals, with the gaseous ozone being more effective than the KTP laser. However, 2.5% NaOCl was superior in its antimicrobial abilities compared with KTP laser and gaseous ozone.

Materials and methods: Forty-five extracted human mandibular premolar teeth were used in this study. Root canals of the teeth were filled before being randomly assigned to three groups. In group 1, gutta-percha was removed with K3 (SybronEndo, West Collins, CA, USA) rotary NiTi instruments. In group 2, gutta-percha was removed with R-Endo (Micro-Mega, Besancon, France) rotary NiTi instruments. In group 3, gutta-percha was removed using Hedstrom files (Dentsply Maillefer, Ballaigues, Switzerland). Debris extruded from the apical foramen was collected into Eppendorf tubes. The liquid inside the tubes was dried, and the debris in each group was weighed and compared. Data were statistically analyzed using one-way analysis of variance, and Kruskal-Wallis test and Mann-Whitney U test. Results: Although all retreatment techniques resulted in apical extrusion, groups 1 and 2 produced significantly less apical extrusion than group 3 (P < 0.05). No statistically significant difference was found between groups 1 and 2 (P > 0.05). Conclusion: All retreatment techniques produced extruded debris during endodontic retreatment; however, both rotary NiTi systems were associated with less apical extrusion than manual instrumentation with Hedstrom files.

Materials and Methods: Sixty freshly-extracted human premolars were randomly assigned to four equal groups: group 1, 37% phosphoric acid; group 2, 37% phosphoric acid + 2% CHX; group 3, 37% phosphoric acid + KTP laser; and group 4, CPB. The teeth were kept in distilled water for 24 h, and thereafter subjected to 500 thermal cycles. Then specimens were sealed with nail varnish, stained with 0.5% basic fuchsin for 24 h, sectioned, and evaluated under a stereomicroscope. Microleakage was scored with regard to the adhesive-tooth interface and the bracket-adhesive interface at both incisal and gingival margins by the same person. Statistical analysis was accomplished by one-way ANOVA and the Kruskal-Wallis test, with significance set at p = 0.05. Results: Microleakage was observed in all groups. No statistically significant difference was observed among all groups in terms of microleakage when bracket-adhesive and bracket-enamel interface along both gingival and incisal margins was evaluated (p > 0.05). Conclusions: The lowest microleakage scores were observed in the control group. CPB, KTP, and CHX groups did not show significant differences with the control group (p > 0.05), but the mean scores of the CHX group were higher than those of the other two experimental groups.Öğe Effects of dentin surface treatments including Er,Cr:YSGG laser irradiation with different intensities on the push-out bond strength of the glass fiber posts to root dentin(INFORMA HEALTHCARE, 2015) Kirmali, Omer; Kustarci, Alper; Kapdan, Alper; Er, KursatObjective. Intra-canal post systems are commonly used to restore root-filled teeth. Bond strengths of the posts can be affected by various surface treatments of the post or the dentin. The aim of this study was to evaluate the effects of dentin surface treatments including erbium-chromium; yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser irradiation with different intensities on the push-out bond strength of the glass fiber posts to root dentin. Materials and methods. Forty single-rooted human maxillary incisors were filled and post spaces were prepared. After these procedures, the specimens were divided randomly into four groups according to the dentin surface treatments, as follows: (i) untreated surface (control), (ii) 1W Er,Cr:YSGG laser application, (iii) 2W Er,Cr:YSGG laser application and (iv) 3W Er,Cr:YSGG laser application. Then the posts were cemented into the root canals using dual-cured resin cement. Bonded specimens were cut into 1-mm-thick slices and push-out tests were performed using a universal testing device. All specimens were loaded until fracture and the failure modes were evaluated with a stereomicroscope at 32x magnification. Representative specimens were analyzed by scanning electron microscopy. Data were analyzed using a one-way ANOVA, Tukey and Wilcoxon tests. Results. The bond strength values ranged from 3.22-4.68 MPa. There were no statistically significant differences among the groups, regardless of the different levels. The coronal and middle levels of the post space had significantly higher bond strength values compared with the apical level (p < 0.05). Conclusion. Er,Cr:YSGG laser irradiation with different intensities did not increase the bond strength of the fiber posts to the root canal dentin walls.Öğe Effects of direct and indirect bonding techniques on bond strength and microleakage after thermocycling(KOREAN ASSOC ORTHODONTISTS, 2009) Ozturk, Firat; Babacan, Hasan; Nalcaci, Ruhi; Kustarci, AlperObjective: The purpose of this study was to compare the shear bond strength (SBS) of brackets and microleakage of a tooth-adhesive-bracket complex bonded with a direct and an indirect bonding technique after thermocycling. Methods: Fifty non-carious human premolars were divided into two equal groups. In the direct bonding group a light-cured adhesive and a primer (Transbond XT) was used. In the indirect-bonding group, a light-cured adhesive (Transbond XT) and chemical-cured primer (Sondhi Rapid Set) were used. After polymerization, the teeth were kept in distilled water for 24 hours and thereafter subjected to thermal cycling (500 cycles). For the microleakage evaluation, 10 teeth from each group were further sealed with nail varnish, stained with 0.5% basic fuchsin for 24 hours, and examined under a stereomicroscope. Fifteen teeth from each group were used for SBS testing with the universal testing machine and adhesive remnant index (ARI) evaluation. Data were analyzed using the Mann-Whitney U test, Chi-square test, and Fisher's exact test. Results: There were no statistical differences on SBS and microleakage between the two bonding techniques. The indirect bonding group had a significantly lower ARI score. Bracket failures were obtained between enamel-resin interfaces. Conclusions: The type of bonding technique did not significantly affect the amount of microleakage and SBS.

The purpose of this study was to evaluate the effect of three different irrigating solutions (17% EDTA, 10% citric acid and 2.5% NaOCl) and KTP laser irradiation on apical leakage using an electrochemical method. Materials and methods. Sixty extracted single-rooted human teeth with mature apices were instrumented up to a size 35 K-file. After using each file and before proceeding to the next, canals were irrigated with 2 ml of 2.5% NaOCl. All teeth were then randomly divided into four groups. In group 1, the root canals were irrigated with a final flush of 17% EDTA. In group 2, the root canals were irrigated with a final flush of 10% citric acid. In group 3, the root canals were irradiated with KTP laser at 1W, 4.45 J/cm(2). In group 4, the root canals were irrigated with a final flush of 2.5% NaOCl. The root canals were then filled using the cold lateral condensation method. Apical leakage was evaluated using an electrochemical method over a period of 10 days. Data were analysed using Tukey HSD and Friedmann tests with p = 0.05 as the level for statistical significance. Results. The 17% EDTA and 10% citric acid groups had statistically less apical leakage than the 2.5% NaOCl group at days 7, 8, 9 and 10 (p < 0.05); however, no significant differences were found between the tested groups at the other time intervals (p > 0.05). No significant difference was found between the KTP laser group and other groups tested at all time intervals (p > 0.05). Conclusion. All groups were unable to eliminate apical leakage. However, final irrigation with 17% EDTA and 10% citric acid following root canal preparation reduced postobturation apical leakage compared with 2.5% NaOCl irrigation. When KTP laser and the other three irrigants were compared, no siginificant difference was found.Öğe Efficacy of Surface Roughness and Bond Strength of Y-TZP Zirconia After Various Pre-Treatments(MARY ANN LIEBERT, INC, 2015) Kirmali, Omer; Kustarci, Alper; Kapdan, Alper; Er, KursatObjective: The aim of this study was to evaluate surface roughness (SR) and the influence of various surface treatments (STs) on the veneer ceramic shear bond strength (SBS) to Y-TZP zirconia. Background data: STs can improve the bonding properties of zirconia ceramics. However, little is known about the effect of Er,Cr:YSGG laser irradiation on SBS between zirconia and veneer ceramic/resin cement. Methods: Eighty ceramic discs of yttria-tetragonal zirconia polycrystals (Y-TZP) were prepared, and specimens were divided into eight groups (n=10): untreated (control), air abrasion, and Er,Cr:YSGG laser irradiation with different energy intensities (1-6 W). Average SR of each specimen was determined with a profilometer, and a veneering ceramic recommended for zirconia was fired into cylinder-shaped Y-TZP specimens. SBS test was performed for each specimen at a crosshead speed of 1 mm/min, and the average means of SBS and SR were calculated. Fracture modes and the surface topography were evaluated with various microscopes after STs. Data were analyzed by using one way analysis of variance (ANOVA) and Tukey honest significant difference (HSD) tests. Results: The highest mean force value was observed in the air abrasion group, and followed by 6 and 5 W laser irradiations, respectively. The difference between control and air abrasion groups was found to be statistically significant (p<0.05). All laser irradiations increased the SBS value, but 1 and 2 W laser irradiations showed no statistically significant differences compared with the control group. However, the SR value for air abrasion group was significantly higher than that of the control group and 1 W (p<0.05), and there were no significant differences between the SR of all the laser groups and the control group. Conclusions: The result of this study showed that STs with air abrasion and high laser energy intensities (3-6W), can improve the bonding properties of Y-TZP zirconia.Öğe The efficacy of two rotary NiTi instruments and H-files to remove gutta-percha from root canals(MEDICINA ORAL S L, 2012) Akpinar, Kerem-Engin; Altunbas, Demet; Kustarci, AlperObjective: The aim of this study was to evaluate the efficacy of R-Endo (R) and K3 (R) rotary nickel-titanium instruments compared with manual instrumentation with H-files, with use of a solvent, for removal of gutta-percha during retreatment. Study design: Forty five freshly extracted human single-rooted teeth, each with one root canal, were instrumented with K-files and filled using cold lateral compaction of gutta-percha and AH 26 (R) sealer. The teeth were randomly divided into three groups of 15 specimens each. Removal of gutta-percha was performed with the following devices and techniques: Group 1 (H-files), Group 2 (R-Endo (R)), and Group 3 (K3 (R)). The specimens were rendered transparent for the evaluation of the area of remaining gutta-percha/sealer in buccolingual and mesiodistal directions. Statistical analysis as performed by using one-way ANOVA and Kruskal-Wallis tests (p=0.05). Results: All retreatment techniques used in this study left some filling material inside the root canal. Images in buccolingual and mesiodistal directions showed no significant differences between the groups (p>0.05). Conclusions: Under the experimental conditions, the remaining filling material after retreatment was similar for each group.Öğe Evaluation of the shear bond strength of zirconia to a self-adhesive resin cement after different surface treatment(Wroclaw Medical Univ, 2021) Akar, Turker; Dundar, Ayse; Kirmali, Omer; Ustun, Ozlem; Kapdan, Alper; Er, Hakan; Kustarci, AlperBackground. Bond stability between zirconia and a self-adhesive resin cement is a major concern, and only limited evidence about its longevity is currently available. Moreover, no study has yet comprehensively evaluated the influence of different power levels of the neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser irradiation on the shear bond strength (SBS) of zirconia to a self-adhesive resin cement. Objectives. The aim of this study was to evaluate the SBS of pre-sintered and sintered zirconia to a selfadhesive resin cement after various treatment (air abrasion and the Nd:YAG laser irradiation at varying power levels -1 W, 2 W and 3 W). Material and methods. Ninety-nine zirconia specimens were prepared and divided into 3 groups: control (with no surface treatment); and pre-sintered and sintered groups with surface treatment. Surface treatment was applied before sintering in the pre-sintered group and after sintering in the sintered group. After following all protocols, a resin cement was layered on the zirconia surface. Shear bond strength was measured using a universal testing machine. The results were subjected to the statistical analysis. The surface topography and phase transformation of zirconia were evaluated using the atomic force microscopy (AFM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses after surface treatment. Results. The laser irradiation (3 W, 1 W and 2 W) of the pre-sintered zirconia surface resulted in the highest SBS values (p < 0.001), while the lowest SBS values were obtained with airborne particle abrasion of the pre-sintered and sintered zirconia surfaces. Conclusions. Laser irradiation increased the SBS of pre-sintered zirconia to a resin cement. Surface treatment with air abrasion had a lesser effect on the SBS values.Öğe Evaluation of Various Pretreatments to Fiber Post on the Push-out Bond Strength of Root Canal Dentin(ELSEVIER SCIENCE INC, 2017) Kirmali, Omer; Ustun, Ozlem; Kapdan, Alper; Kustarci, AlperIntroduction: The aim of this in vitro study was to compare the effect of different pretreatments (fiber post) with the laser-activated irrigation (LAI) technique (for removal of the smear layer) on root canal dentin in terms of push-out bond strength (PBS) in a fiber post. Methods: Fifty freshly extracted mandibular single-rooted premolars were prepared, and LAI was applied to all roots (17% EDTA was 5 mL for 120 seconds with an erbium, chromium:yttrium-scandium-galliumgarnet laser [0.50 W, 20 Hz, 25 m1]). In addition, 50 quartz fiber posts were randomly assigned to 5 groups (n = 10) according to the surface treatments as follows: group S (sandblasting), group N1 and group N2 (neodymium:yttrium-aluminum-garnet laser irradiation [2 W, 200 ml, 10 Hz, with pulse durations of 180 or 320 microseconds), group HF (9.7% hydrofluoric acid etched), and group C (control with no treatment). Dual-cure resin cement was adhered onto the fiber posts after they were covered with a silane agent, and then the posts were placed into the canal space using a Lentulo spiral. The PBS test was performed after all specimens were transversally sectioned (root slices of 1-mm thickness). Data were analyzed with 1-way analysis of variance/Tukey post hoc test (alpha = 0.05). Results: The highest PBS value was observed in group S (middle part), and the lowest value was observed in group C (apical part). There were no statistical differences among the groups regardless of the part. Furthermore, when the PBS values of the different parts of dentin were compared within treated groups, significant differences were observed in all groups except group N2 (P < .05). Conclusions: Within the limitations of this study, it can be concluded that the LAI technique when used with 17% EDTA had a significant effect on the amount of smear layer removed from the root canal dentin, which was also detected in the fracture pattern (adhesive failure [resin-post interface]). However, the various treatments of the fiber post did not improve the PBS of the root dentin.Öğe Fracture Resistance of Root-Filled Maxillary Premolar Teeth Restored with Current Dentin Bonding Adhesives(Univ Zagreb, Sch Dental Medicine, 2008) Siso, Seyda Herguner; Er, Kursat; Hurmuzlu, Feridun; Kustarci, Alper; Akpinar, Kerem EnginObjective: The aim was to study and compare the fracture resistance of root-filled premolar teeth restored with various dentin bonding adhesives (DBAs). Material and Methods: Eighty extracted single-rooted human maxillary premolar teeth were randomly assigned to eight groups (n=10). Group 1 (control) did not receive any preparation. From groups 2 to 8, the teeth were root filled and MOD cavities were prepared. Group 2 remained unrestored. Groups 3-8 were restored using the following DBAs: iBond (Heraeus Kulzer), G-Bond (GC Co.), Xeno III (Dentsply/Caulk), AdheSe (Ivoclar Vivadent), Clearfil Protect Bond (Kuraray) and Clearfil Tri-S Bond (Kuraray); all preparations were further restored with a resin composite (Renew, Bisco). All specimens were then stored in 100% humidity at 37 degrees C for 24 h, followed by thermal cycling 500 times between 5 degrees and 55 degrees C. Compressive loading of the teeth was performed by a universal testing machine at a crosshead speed of 1 mm min-1 until failure. The data were recorded in Newton (N) and were submitted to one-way ANOVA and Tukey post-hoc test. Results: The mean loads necessary to fracture the samples in each group were: group 1: 984.00 +/- 116.27a, group 2: 167.30 +/- 47.26b, group 3: 872.30 +/- 164.99a, group 4: 848.70 +/- 157.84a, group 5: 916.30 +/- 246.19a, group 6: 863.20 +/- 197.69a, group 7: 802.20 +/- 183.84a, group 8: 870.70 +/- 126.48a. Similar letters indicate statistically similar values (P>0.05). Conclusion: The type of DBAs had no influence on the fracture resistance of teeth.Öğe The Influence of Various Irrigants on the Accuracy of 2 Electronic Apex Locators in Locating Simulated Root Perforations(ELSEVIER SCIENCE INC, 2017) Altunbas, Demet; Kustarci, Alper; Toyoglu, MustafaIntroduction: The aim of this study was to assess the accuracy of the Dentaport ZX (Morita Co, Kyoto, Japan) and the Rootor (Meta Biomed, Cheongwon-gun, Korea) electronic apex locators (EALs) in detecting root perforations in dry conditions and in the presence of the following irrigation solutions: 2.5% sodium hypochlorite (NaOCI), 0.9% saline solution (NaCI), and 17% EDTA. Methods: Twenty extracted, single-rooted human teeth were perforated artificially in the middle section. The actual canal lengths (ALs) up to the perforation site were determined, and then the teeth were embedded in an alginate mold. The electronic measurements of the perforations were obtained using a size 20 K-file by each EAL in various conditions. For each tooth, the AL was subtracted from the electronic length of the perforation. Statistical analyses were performed using the Friedman and Wilcoxon signed rank tests at a significance level of P <.05. Results: The most accurate measurements for both EALs were obtained in dry conditions. Among the irrigation solutions in the Dentaport ZX group, EDTA gave the most accurate results, and NaOCl gave the least accurate ones. However, measurements with NaCI were closer to the AL than those obtained with EDTA for the Rootor group. Significant differences were noted among the EALs when the measurements were taken with NaOCI, NaCI, and EDTA (P <.05). Conclusions: The Dentaport ZX was more accurate compared with the Rootor in the presence of different irrigants. The content of the root canal affected the accuracy of both EALs. The most accurate measurements were obtained in dry canals.Öğe Knowledge of first-aid measures of avulsion and replantation of teeth in schoolchildren with sports education(Cumhuriyet University Faculty of Dentistry, 2011) Kapdan, Arife; Buldur, Burak; Kapdan, Alper; Ünal, Murat; Kustarci, AlperObjectives: The objective of this study was to assess the present knowledge level of emergency measures for tooth avulsion in schoolchildren with sports education in Sivas. Materials and Methods: A total of 112 schoolchildren aged 15-18 years old, were interviewed bu professionals using a standardized method to score knowledge about tooth avulsion and replantation. The following fields of knowledge were assessed tooth avulsion and replantation principles, avulsed permanent/primary teeth, cleaning of avulsed tooth before replantation, extra alveolar time and storage media. Chi-square test was used for statistical analysis. Results: Regardless of age group, there were generally a low knowledge level regarding tooth avulsion, replantation, extra alveolar time and storage media. When comparing special knowledge level of the avulsion and replantation of the permanent/primary teeth according to the age groups, the differences between age groups were found statistically important. 16 and 17 age groups had middle knowledge level. The lowest knowledge level was in 15 age group. Concerning with storage media, 60,4% of students preferred water and 11,4% of students preferred milk for storage media. Conclusions: We conclude that first-aid knowledge in schoolchildren with sports education is low on avulsion and replantation of teeth and the knowledge level of first-aid measures on avulsion and replantation of teeth could be increased through intervention programs.Öğe Nonsurgical endodontic treatment of a large cyst-like periradicular lesion(ELSEVIER TAIWAN, 2014) Kustarci, Alper; Kosger, Husan Huseyin; Er, Kursat…Öğe Nonsurgical endodontic treatment of dens invaginatus in a mandibular premolar with large periradicular lesion: A case report(ELSEVIER SCIENCE INC, 2007) Er, Kuersat; Kustarci, Alper; Oezan, Uelkue; Tasdemir, TamerThis case report describes the treatment of a dens invaginatus in a mandibular premolar with large periradicular lesion. A nonsurgical endodontic treatment was performed to tooth #28. During the treatment procedure, calcium hydroxide and a triple antibiotic paste were separately used for intracanal dressing. The apical third of the canal was obturated with mineral trioxide aggregate (MTA), and the remaining canal space was obturated with gutta-percha and AH 26 root canal sealer, using a lateral condensation technique. At follow-up examination after 1 year, the tooth was asymptomatic and radiographically showed repair of the lesion. Healing was achieved without any need for further endodontic surgical intervention.Öğe Stabilization of autotransplanted teeth using thermoplastic retainers(MEDICINA ORAL S L, 2011) Isa-Kara, Muhammed; Sari, Fatih; Emre-Coskun, Mehmet; Kustarci, Alper; Burak-Polat, Hidayet; Ozdemir, Hakan; Polat, SerkanObjective: Different fixation techniques have been used for stabilization of autotransplanted teeth. Because rigid or extended fixation periods can cause complications such as ankylosis and disturbances of pulpal revascularization, our aim was to evaluate an alternative technique, a removable splint, for improving the success rate of autotransplanted molar teeth. Study Design: In 44 patients, (20 male and 24 female patients), 45 transplanted teeth were analyzed. These cases were followed for 31 to 47 months after operation. Transplanted teeth were evaluated after use of a thermoplastic retainer for 1 month, in terms of success rate and dissatisfaction with this apparatus. The primary stability, ankylosis, and root resorption were also analyzed. Results: To date, 1 transplant was extracted after 6 months due to unpreventable periapical root inflammation, and 2 transplants were extracted after one year due to external root resorption. Although 2 ankylosed transplants were still functional after an average follow-up period of three years, with no dissatisfaction by the patients, these cases were treated as failures because of the probable risk for external root resorption. The remaining 40 (88.8 % success rate) transplants remained asymptomatic and functioning for a mean follow-up period of 37 months. In the assessment of dissatisfaction with the thermoplastic retainer, 36 (81.8 %) patients had no or little dissatisfaction, 4 (9 %) patients had very appreciable or excessive dissatisfaction, and 4 (9 %) patients had moderate dissatisfaction. Conclusions: A thermoplastic retainer for use after autotransplantation of third molar teeth is a reasonable and useful method and a good alternative to conventional rigid or semi-rigid splints. This technique was especially useful in autotransplanted teeth that had poor stability, i.e., in cases in which it is conventionally advised to use long-term rigid or semi-rigid splints.Öğe The evaluation of tooth health status of preschool children in sivas(Cumhuriyet University Faculty of Dentistry, 2010) Kapdan, Arife; Kustarci, Alper; Kapdan, Alper; Buldur, Burak; Arslan, DilaraPurpose: The purpose of this study was to determine, the df(t) and df(s) scores of preschool children and evaluate the caries distribution according to age and sexs.
