Risk Factors Associated with Cusp Fractures in Posterior Permanent Teeth—A Cross-Sectional Study

Objectives: This cross-sectional study aimed to evaluate the frequency and risk factors associated with cusp fractures in posterior permanent teeth. Methods: Patients presented on teeth, clinically assessed up 7 days after event, requesting dental treatment at two public services were included this study. Fractured teeth already treated, antagonist absence, or prosthesis (total removable) excluded. Demographic clinical data collected draw patient profiles establish how affected individually. Statistical analysis was performed by Fisher exact test, uni- multivariate logistic regression (? = 0.05). Results: One hundred seventy-seven (177) patients from 16 66 years old (±41.56), 1998 2016, Non-functional lingual cusps a higher fracture than functional buccal cusps, respectively. Fractures more common isthmus wider 1/3 of intercuspid distance and/or three restored surfaces. Teeth endodontic subgingival fracture. On type location significantly associated, being that total 3.2 times likely occur partial fractures, 3.62 supragingival fractures. Conclusion: Indications classic protection (LUBL) refuted since, generally, nonfunctional fractured cusps. However, upper pre-molars showed lower molars In general, most prevalence severe level). where restoration had an involved Most did not show previous symptoms signs. Overall,
