EVALUATION OF TOTAL AND PARTIAL EDENTULOUS JAWS USING PANORAMIC RADIOGRAPHY

Öz

Aim: Panoramic radiography is a diagnostic modality for providing a view of the entire maxillofacial region and used as an initial screening tool to examine partially and completely edentulous jaws in pretreatment assessment. Material-method: This study included digital panoramic images of 321 partially and totally edentulous patients. The images were evaluated for positive radiographic findings including presence of retained radiolucencies, radiopacities, proximity of the mental fragments

Aim: Panoramic radiography is a diagnostic modality for providing a view of the entire maxillofacial region and used as an initial screening tool to examine partially and completely edentulous jaws in pretreatment assessment.

Material-method: This study included digital panoramic images of 321 partially and totally edentulous patients. The images were evaluated for positive radiographic findings including presence of retained root fragments, impacted teeth,  radiolucencies, radiopacities, proximity of the mental foramen and  maxillary sinus to the residual alveolar ridge.

Results: Totally 538 edentulous jaws were examined in 321 individuals (51.1 % females, 48.9 % males) mean aged 57.3 (standard deviation=11.5). The rate of completely edentulous jaws was 29 % (n=156) and the rate of partially edentulous jaws was 71 %. Prevalence of one or more positive radiographic findings was found to be 51 %. Of the radiographic findings, 49.4 % was in females and 50.6 % in males. The most frequent finding was retained root fragments (15.6 %), followed by location of the maxillary sinus close to the alveolar crest (10.6 %), radioopacities (9.3 %), impacted teeth (8 %), location of the mental foramen on the crest (6.8 %) and radiolucencies (1.2 %).

Conclusion: Prevalence of positive radiographic findings was found to be relatively high in clinically healthy looking edentulous patients in this study. This result confirmed that pretreatment panoramic examination is necessary to detect pathologies and requirement of any dental procedure for a successful prosthodontic rehabilitation.
