Microbial Profile and Endotoxin Levels in Primary Periodontal Lesions with Secondary Endodontic Involvement.

This study was carried out to investigate the microbial profile and endotoxin levels of endodontic-periodontal lesions of periodontal origin. Periodontal and endodontic samples were taken from periodontal pockets and necrotic root canals of 10 teeth with endodontic-periodontal lesions. Evidencing of 40 different bacterial species were determined in each endodontic and periodontal sample using the checkerboard DNA-DNA hybridization method and Kinetic chromogenic LAL assay was used for quantification of endotoxins.

Clinical and Microbiological Evaluation of Povidone-Iodine 10% as an Adjunct to Nonsurgical Periodontal Therapy in Chronic Periodontitis: A Randomized Clinical Trial.

Aim: To evaluate the clinical and microbiological effects of irrigation with 10% povidone-iodine (PVP-I) as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis (ChP).

Methods: Thirty-six subjects with ChP were randomly assigned to receive SRP + irrigation with saline solution (control group) or SRP + irrigation with 10% PVP-I (test group). Subjects received clinical and microbiological evaluation at baseline, 30 and 90 days post-treatment.

Comparison of two power densities on the healing of palatal wounds after connective tissue graft removal: randomized clinical trial.

Unlabelled: Connective tissue graft (CTG), which is considered to be among the best techniques for treating gingival recession, has presented stable long-term results. However, this technique causes morbidity and discomfort in the palatine region due to graft removal at that site. A previous study reports that photobiomodulation (PBM) using a dosage of 15 J/cm(2) may improve wound healing and the patient's postoperative comfort.

Evaluation of different periods of estrogen replacement onset in the tibia of ovariectomized rats.

Background And Aims: Estrogen deficiency results in increased bone turnover and can lead to osteoporosis. Hormone replacement therapy (HRT) seems to be the most effective means of reducing bone loss and fractures. However, the effects of the period of HRT onset on bone tissue require further elucidation.

Smoking enhances bone loss in anterior teeth in a Brazilian population: a retrospective cross-sectional study.

The aim of the present study was to radiographically evaluate the effect of smoking on bone loss resulting from chronic periodontitis. Periapical radiographs were analyzed of 80 patients with chronic periodontitis (40 current or former smokers and 40 never-smokers) that attended a private periodontal practice. The smokers or former-smokers with a minimum consumption of 10 cigarettes/day for a period of over 10 years were selected.
