Estado periodontal del segundo molar adyacente al tercer molar mandibular Clínica UCSG A 2018.

Abstract

Introduction: Third molars have an unusual eruption pattern. Studies suggest that, due to the position and angulation of these, various pathologies could occur in the adjacent molars, such as periodontal problems and the appearance of distal caries. Objective: To evaluate the periodontal status of mandibular second molars adjacent to mandibular third molars. Materials and Methods: A clinical and radiographic study of transversal and descriptive observational type was carried out. We worked with a sample of 277 patients who went to the Odontological Clinic of the UCSG to perform extractions of third molars in the period A-2018. An intraoral clinical examination was performed in which the following variables were observed: probing depth, gingival state and presence of caries in mandibular second molars. In addition, panoramic radiographs of the patients were reviewed to determine the position of the mandibular third molar and the level of the distal bone crest of the second molars. Results: The depth of the distal probing of the mandibular second molars was normal (from 1 to 3mm) in 31% of the cases, while 69% found depths greater than 3mm. Regarding the presence of bone loss, in 43% of cases there was no loss, in 35% of cases there was slight loss, 22% presented moderate loss and only 1% had severe loss. Conclusion: The presence of mandibular third molars significantly affects the periodontal state of the adjacent second molar, which can lead to periodontal pockets, bone loss and caries in the distal area of these.
