Assesment of fixed partial denture retainers radiographically.

Purpose: Most of dental patients prefer reconstruction with fixed partial dentures (FPD) rather than removable ones because of comfort, psychological and social advantages of FPDs. However, a FPD which does not implement required standards and rules of FPDs may cause different dental problems. The aim of the present study was evaluation FPDs in terms of complying Ante’s law, secondary caries and periapical lesions radiographically. Methods: A total of 380 panoramic radiograph belongs to patients applied to the clinics of Akdeniz University Faculty of Dentistry examined in the present study. Current abutments of FPDs were evaluated in terms of complies with the Ante’s law, secondary caries and periapical lesions radiographically. Periapical lesion classification was performed according to periapical index (PAI). Statistical analysis were performed using SPSS 20.1 and Microsoft Excel software program. Results: The present study comprised panoramic radiographs belongs to166 women and 214 men with an age range of 25 to 83 years old (46.0+- 11.1 years for men and 49,4+-11,0 years for women). No relationship was observed between gender and caries formation (p>0,05). Distribution of periapical lesions was found 23% class III, 1.8% class IV, 1.3% class V according to PAI. More caries were observed among the restorations which doesn’t meet the requirements of Ante’s law (p<0,05). Conclusions: According to the results of the present study, the rehabilitation of edentulous regions with conventional FPDs may cause different periapical pathologies and caries. Careful evaluation of abutments regarding to Ante’s law and periapical status may decrease the complications that could be observed in long term prognosis of FPDs
