Long-term effects of root-resective therapy in furcation-involved molars. A 10-year longitudinal study.

The present investigation was designed to evaluate the long-term effect of root-resective therapy in the treatment of furcation-involved molars. The patient sample included 72 patients, 21-62 years of age, who presented periodontal lesions in the posteriors segments of the mouth including furcation involvement of various degrees. After an initial examination, each patient was subjected to a series of full-mouth scaling and root planing. They were recalled 1-3 months later for a presurgical examination and subsequently underwent the corrective phase of therapy. During the surgical procedure, the furcation-involved teeth were subjected to root-resective therapy in conjunction with osseous recontouring and apically positioned flaps (test sites). A surgical procedure identical to the test procedure was performed in the non-furcation-involved teeth (control sites) with the exception of the root resection. At the completion of the active phase of treatment, 175 test and 175 control sites were available for the study. After a period of 6 months of healing and plaque control supervision following surgical procedures, the patients were recalled for a baseline examination. They were then enrolled in a maintenance program including professional tooth cleaning every 26 months. The patients were re-examined 3, 5 and 10 years post-operatively. The results of the assessments demonstrated that the survival rate, during the 10-year period of observation, reached 93% at test and 99% at control sites. The positive treatment outcome at the root-resected, furcation-involved teeth as well as at non-furcation-involved teeth was probably the consequence of the reestablishment of a tissue morphology favorable for oral hygiene and careful plaque control by the patients.

A retrospective analysis of the perio-prosthetic aspect of teeth re-prepared during periodontal surgery.

This paper describes a retrospective study in which the gingival and periodontal status was assessed at crowned and natural teeth. 510 crowned teeth and 510 natural teeth in 109 subjects were examined. The time elapsed between active therapy and the clinical examination was: (i) 1 to 3 years for 270 teeth; (ii) 3 to 5 years for 168 teeth; (iii) 6 to 9 years for 72 teeth. 90% of the patients were on a recall schedule that required prophylaxis once every 3 months; 8% returned every 6 months and 2% once a month. Plaque index and gingival index were assessed at 4 sites per tooth and pocket depth at 6 sites per tooth, the highest reading per tooth being used for the statistical analysis. The results indicated that there was no difference in plaque and gingival indices between crowned and natural teeth. In addition, the gingival status of the crowned teeth was good, irrespective of the position of the crown margin (subgingival, at the gingival margin or supragingival).

Methylene blue dye spraying method in patients with ulcerative proctitis: a comparative study with morphological findings and functional capacity of the rectal epithelium.

Methylene Blue dye spraying method is currently used in the endoscopic assessment of the colonic mucosa of patients with chronic ulcerative proctocolitis. We have assessed the validity of this method in the evaluation of the functional capacity of the rectal mucosa in 17 patients with ulcerative proctitis and in 5 normal subjects. The ionic transmucosal fluxes of Na+ and K+ and the potential difference were used as parameters of the mucosal function. Our results indicate that methylene blue dye spraying method can be useful in the functional assessment of the rectal epithelium, especially for differentiating normal subjects and patients with mild ulcerative proctitis.
