The aim of the present study was to evaluate the effects of local tetracycline on the occurrence of alveolar osteitis in rats, and on the microbiota associated to this infection. Forty Wistar rats were randomly assigned to 4 groups (n=10): I - the rats had the maxillary right incisor extracted and the alveolar wound did not receive any treatment; II - adrenaline and Ringer-PRAS were introduced into the alveolar wound; III - the alveolar wound was irrigated with sterile saline; and IV - the alveolar wound was irrigated with an aqueous solution of tetracycline. Microbial samples from the alveolar wounds were collected 2 days after surgery and inoculated on blood agar (with and without 8 microg/mL of tetracycline) and other selective media, and were incubated in either aerobiosis or anaerobiosis at 37 degrees C, for 2 to 14 days.

This article describes an alternative surgical approach to the harvesting of subepithelial connective tissue grafts from thin palates. A partial-thickness flap is raised, and a graft composed of epithelium and connective tissue is removed from the palate. The superficial layer (epithelium and a thin zone of connective tissue) is then dissected from the graft and replaced at the donor site to facilitate faster healing.

Article Synopsis
- * Subgingival plaque samples were collected and cultured, revealing Aa in 40.3% of healthy subjects, 68% of chronic periodontitis patients, 92.86% of aggressive periodontitis patients, and 40.14% of children with gingivitis.
- * The findings indicate a higher detection rate of Aa than previously noted, suggesting its significant role as a native component of the periodontium microbiota and its association
Background: Excisional biopsies of gingival overgrowths, performed with safety margins, frequently result in mucogingival defects. These defects may produce esthetic problems and increase the chances of dentin hyperesthesia and its possibility of hindering oral hygiene.
Methods: Two clinical cases are reported in which gingival overgrowths were removed by excisional biopsy, resulting in unsightly defects.
