Human clinical and histologic responses to Durapatite implants in intraosseous lesions. Case reports.

The healing response following implantation of a nonresorbable ceramic (durapatite) into human periodontal osseous defects was evaluated clinically and histologically. Four tooth-containing blocks were obtained from four patients who had received durapatite implants in osseous defects, each exceeding 4 mm in depth. Each patient was seen for 5 to 13 postsurgical maintenance visits.

Periodontal healing following open debridement flap procedures. I. Clinical assessment of soft tissue and osseous repair.

The healing response of the periodontium was evaluated after periodontal flap and debridement procedures in patients with different levels of postsurgical plaque control. Thirty-one sites in 19 patients were included. Measurements were performed from a fixed reference point presurgically and before reentry surgery.

Tetracycline: a clinical study to determine its effectiveness as long-term adjuvant.

A random double blind crossover study of patients on the effects of tetracycline therapy over a 3-month period revealed that there were no significant differences between the placebo group and tetracycline-treated groups in relation to (1) Gingival Index, (2) Debris Index and (3) Papillary Bleeding. A marked improvement in the Gingival Index occurred after 3 months of treatment in each group resulting from curettage and home care. Papillary bleeding was significantly reduced after 3 months of treatment in the tetracycline group and similar trends were observed in the placebo group.

Salivary composition and calculus formation in patients undergoing hemodialysis.

The purpose of this report is to provide further information regarding oral changes in patients with chronic renal disease who are undergoing hemodialysis. Quantitative changes in salivary flow rate and alterations in the composition of stimulated and unstimulated sliva were studied along with the rate of formation of supragingival calculus. Results revealed a lower salivary flow rate and increased salivary urea concentration in the dialysis group.

Combined orthodontic-periodontal treatment of an infrabony defect. A case report.

A case presentation involving the combined orthodontic-periodontic treatment of a distally inclined mandibular left central incisor with a mesial infrabony defect is reported. Treatment was performed in three phases: (a) the tooth was moved upright (b) periodontal surgery with osseous grafting of the infrabony defect was then performed; and (c) the operative site was reentered 5 months later. The patient was followed and soft and hard tissue changes were documented for 12 months from time of initiation of treatment.

Oxidative phosphorylation in rat oral mucosal mitochondria.

Oral mucosal mitochondria were isolated and characterized morphologically by electron microscopy. Polarographic measurements were made of respiration and oxidative phosphorylation in the mitochondrial preparations. ADP:O ratios approaching or slightly exceeding the theoretical maxima and stabilized respiratory control ratios were achieved with malate + glutamate, succinate and ascorbate-N,N,N1N1 tetramethyl-p-phenylenediamine (TMPD) as substrates.
