Both hand and rotary canal instrumentation resulted in extrusion of debris beyond the apical foramen. No significant difference was observed between K-files and Revo-S system. Open-ended needles were associated with significantly more extruded debris than two side-port needles.
The applicability of the Demirjian method is not suitable for western Turkish children and western Turkish children have a lower degree of dental maturity than that observed in the eastern, northeastern and northern Turkish subjects.
As a result, while all M3 teeth were present in 76.71% of the population studied in the province of Izmir, agenesis of one or more than one M3 tooth was found in the other 23.29% of the patients studied.
It was concluded that shaping and widening of the root canals reduced the fracture resistance of teeth while Thermafil increased the resistance of roots against fracture.
Objectives: The aim of this study was to assess the prevalence and degree of taurodontism in a group of Turkish adult dental patients. Study design: A retrospective study was performed using panoramic radiography of 490 patients ranging in age from 18 to 65. These patients were analyzed for taurodontism. Descriptive characteristics of sex, jaws, and localization were recorded. The data was analyzed using the Pearson chi-square test. Results: Taurodontism was detected in 22.8% of patients and 4.2% of the teeth examined. Anomalies were found in 22.2% of females compared with 23.8% of males. However, no significant difference was found between the genders (p > 0.05). Taurodontism was more distributed in the maxilla than in the mandible. The maxillary third molar was the most commonly affected tooth. Conclusion: According to these results, taurodontism is not uncommon in the Turkish population. However, further studies are required to assess its distribution in the general population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
