Association between severe periodontitis and chronic kidney disease severity in predialytic patients: A cross-sectional study.

Objective: The aim of this cross-sectional study was to evaluate the association between periodontitis and different severities of chronic kidney disease (CKD) in predialytic patients.

Materials And Methods: Demographic, socioeconomic, and medical data of 139 patients from the nephrology service of one university hospital in Porto Alegre, Brazil, were obtained through interview and clinical records. Full-mouth six-sites per tooth periodontal examinations were performed.

Correlation analysis of alveolar bone loss in buccal/palatal and proximal surfaces in rats.

The aim was to correlate alveolar bone loss in the buccal/palatal and the mesial/distal surfaces of upper molars in rats. Thirty-three, 60-day-old, male Wistar rats were divided in two groups, one treated with alcohol and the other not treated with alcohol. All rats received silk ligatures on the right upper second molars for 4 weeks.
