Periodontal and prosthetic risk factors for fractured teeth: A retrospective study Goldberger T., Mor I., Tsesis I., Rosen E . The Maurice and Gabriela Goldschleger School of Dental Medicine, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Background: In this retrospective study a series of 41 cases, in which a tooth fracture was diagnosed and verified, were examined. The prevalence of Periodontal and prosthetic risk factors for fractured teeth was analysed. Objective To expand the knowledge about tooth fracture risk factors. To find new risk factors in the aim of improving the ability to prevent, detect and treat tooth fractures. Material and methods: 687 medical files of patients seeking treatment at Tel Aviv University dental clinics were examined. 41 cases that met the inclusion criteria were tested and analysed in this research. The present study addressed the following types of tooth fractures: Fractured cusp, cracked tooth, Split tooth and Vertical root fracture. The information was organized and analysed in the Microsoft Excel software. Results: Most patients (56.1%) were men. The mean age was 48.4 years. 33 (80.4%) of cases were of fractured posterior teeth, while 8 (19.6%) cases were of anterior teeth. Most (80.5%) of the

fractured teeth have had a root canal treatment done in the past, had a post present in the root canal (65.9%) and was restored with a crown (58.5%). All (41) teeth had occlusal contacts with opposite teeth. Dental implants were present in 12 (29%) cases. In 58.3% of cases the implants were inserted and loaded > 3 years before the fracture was diagnosed. Comparing the group of patients that had dental implants to the group that didn’t have dental implants we observed differences, yet not statistically significant, in age, sex, and tooth type and fracture direction distribution and in the presence of deep periodontal pockets and periradicular pathology. Conclusion: This present study sheds light on various tooth fracture risk factors. It is logical to assume that fractures in teeth adjacent to dental implants are different in certain characteristics in comparison to fractures in teeth that have no relation to dental implants. Additional large-scale research is required in order to further investigate this phenomenon.
