[The clinical results of combined periodontal-orthodontic treatment on patients with periodontitis and labial displacement of incisors].

Purpose: To evaluate the clinical effects of combined periodontal and orthodontic method in treating labial displacement of anterior teeth caused by periodontitis.

Methods: 21 cases with periodontitis and fly-out of anterior teeth were selected. After the inflammation was controlled by essential periodontal therapy, the anterior teeth were allied by edgewise appliances; meanwhile, periodontal care and occlusal adjustment were conducted to control inflammation and occlusal trauma, until normal occlusion was established.

[The clinical effects of hyperbaric oxygen therapy combined with supragingival and sublingual scaling therapy on periodontitis].

Purpose: This study was to observe the clinical effects of hyperbaric oxygen therapy combined with supragingival and subgingival scaling therapy on periodontitis.

Methods: The patients with periodontitis were divided randomly into 3 groups, the supragingival and subgingival scaling therapy group, the hyperbaric oxygen therapy group, the hyperbaric oxygen combined with supragingival and subgingival scaling therapy group. The clinical index and the level of aspartate aminotransferase in gingival cervical fluid (GCF-AST) of the 3 groups were compared pre and post treatment,and the clinical index and the level of GCF-AST of the 3 groups after treatment were compared.

[The effect of initial therapy on periodontal status and saccharified Hb (HbAIc) of patients with type II diabetes mellitus].
