Esthetic management of mucogingival defects after excision of epulis using laterally positioned flaps.

Epulis is a benign hyperplasia of the oral soft tissues. Surgical excision always extends to the periosteum and includes scaling of adjacent teeth to remove any possible irritants. The esthetics of the soft tissues may be compromised, however.

Prevalence and quantification of the uncommon Archaea phylotype Thermoplasmata in chronic periodontitis.

Objective: Chronic periodontitis is a chronic inflammatory disease of the periodontal tissues and is caused by invasion of certain types of bacteria and Archaea, with Methanobrevibacter oralis as the predominant archaeon. In this study, we investigated the prevalence and quantity of the newly discovered Archaea phylotype Thermoplasmata in patients with chronic periodontitis.

Methods: Subgingival plaque samples were obtained from 49 patients with chronic periodontitis and 45 periodontally healthy subjects.
