Prevalence of root dilaceration in adult dental patients in Croatia

Objective. To determine the prevalence and distribution of dilaceration in all tooth groups by using radiographs. Study design. The sample included 953 periapical intraoral radiographs and 488 panoramic radiographs from different caucasian patients. The ages of the patients ranged from 18-65 years. Dilaceration of the root was detected by measuring the degree of deviation from the long axis (deviation 1 908), and evaluating the "bull’ s eye" appearance. The prevalence of root dilaceration for each tooth-type was expressed in percentages. Results. The teeth showing the highest prevalence of root dilaceration were mandibular third molars (24.1%), maxillary first molars (15.3%), second molars (11.4%) and third molars (8.1%). In the mandible, dilacerations were less common than in the maxilla. Conclusions. In the adult population examined in Croatia, dilaceration was most frequently found to affect posterior teeth.
