The hidden consequences of bruxism and periodontitis: A case report of multiple root resorption

Sažetak

Background: Evidence regarding the effects of bruxism and periodontitis on root resorption is scarce and remains controversial in the literature. This case report aims to investigate the potential relationship between chronic periodontitis, severe bruxism, and aggressive external root resorption affecting multiple teeth in a patient with no systemic predisposition. Materials and Methods: Following clinical and conventional radiographic (panoramic and periapical) examinations, Cone-Beam Computed Tomography (CBCT) was performed for a detailed analysis of the resorptive lesions. An affected tooth with an extraction indication was subjected to histopathological examination. To exclude potential systemic etiologies, a comprehensive laboratory workup was conducted, including differential blood count, erythrocyte sedimentation rate, Hb%, alkaline phosphatase, T3, T4, TSH, serum potassium, and serum calcium levels. Results: Panoramic radiographs revealed cervical resorption in tooth #13 and a radiolucent area in the apical region of tooth #26. CBCT analysis confirmed localized external root resorption in the mesial root of tooth #26, accompanied by apical periodontitis involving all three roots. Histological findings confirmed the diagnosis of ERR, while the radiographic appearance of tooth #13 supported a suspicion of multiple external root resorption. Hematological and biochemical analyses showed no systemic pathology that could increase susceptibility to resorption.Conclusion: After excluding all other etiological factors, it was concluded that the severity and extent of the root resorption in this case may be associated with the combined effects of the patient's periodontitis and excessive occlusal forces related to severe bruxism.
