Associação entre classificação radiográfica e técnica cirúrgica nas exodontias de terceiros molares inferiores.

Abstract

Introduction: The third molar surgeries represent an important chapter among the oral and maxillofacial surgical modalities. Radiographs are necessary for diagnosis, preoperative planning and choice of technique for this type of procedure. Materials and method: A retrospective study was carried out, with the descriptive analysis of the data. The sample consisted of 100 patients (n = 100) from the spontaneous demand who sought out the Dental Clinic of UFC (Ceará’s Federal University) - Campus Sobral, and who followed the inclusion criteria: patient with panoramic radiography, free of active periodontal disease and tooth with at least two thirds of root formation; and as exclusion criteria: patients with associated bone pathologies, teeth with less than two thirds of root formation and patients who did not wish to participate in the study. Results: Patients included in the study were from 18 to 40 years of age, most of them male, with complaints of pain. Using the radiographic classification of Pell & Gregory, the most found positions were 1A (35%), 2B (28%) and 2A (17%). The most prevalent surgical techniques were the open ones. Could be done the extraction by closed surgical technique (forceps or lever) (n = 27), with flap preparation plus osteotomy (OST) (n = 25) and flap plus osteotomy plus odontostomy (ODS) (n = 48). Conclusion: Teeth with radiographic classification, grade of inclusion and different preoperative plans had the same protocol (flap + OST + ODS) in the surgical act. It is evident that radiographic classification stills an effective method to aid in operative planning, but it can be complemented by other diagnostic standards, such as a specific classification of the root anatomy.
