[Clinical studies on pulpitis and periapical periodontitis caused by traumatic occlusion].
89 cases including 100 teeth with pulpitis and apical periodontitis caused by traumatic occlusion were clinically observed. All teeth are caries-free, no any dental disease, and no pocket formation. But there is a distinct evidence of marked occlusal trauma, such as premature contact and occlusal interference. The single-root teeth are usually involved. When subjected to vitality testing the teeth associated with the periapical lesions sometimes yield positive response (about 30%). The result of investigation endodontic treatment demonstrated that the presence of predisposing factors of trauma from occlusion led to decrease of endodontic success.
