RESUMEN
Objective: To determine a probabilistic model that represents the likelihood of the event Dental Pain to occur in Brazilians patients affected by hereditary coagulopathies. Material and Methods: In this cross-sectional study, information on use and access to dental services, oral morbidity, self-perceived oral health and behavioral health habits were obtained through semi-structured questionnaire and analyzed by means of logistic regression. Results: High prevalence of dental caries was observed for children aged 1-5 years (50%) and for adolescents aged 13-19 years (66%). Cumulative pattern of dental caries in the age groups of 20-35 years and 36-59 years was observed. Most patients did not report pain in the last six months prior to the survey (24.5%). It was observed that searching for dental care for the last time in case of localized pain (OR=26.7), for feeling uncomfortable when brushing teeth (OR=7.3) and difficulty searching for health professionals, not only the dentist (OR 3.7) was considered risk factors for the determination of Dental Pain diagnosis. However, if the patient has mild hemophilia A (OR=0.21), this likelihood decreases, being thus a protective factor. Conclusion: Patients affected by hereditary coagulopathies have high prevalence of caries, indicating the cumulative nature of this disease, which suggests the symptomatic effect of Dental Pain.
