Progress of ossification and epithelialization of wounds after simple or surgical extractions of teeth in rats with chronic renal failure: an experimental study.

Our aim was to investigate the progress of wound healing after simple and surgical removal of the first two molars of the right and left maxillary segments, respectively, in Wistar rats with experimentally induced moderate chronic renal failure (CRF). Sixty Wistar rats were divided into two groups of 30 rats each: experimental and control. CRF was induced in the experimental group by an intraperitoneal injection of cisplatin, 5 mg/kg body weight (BW) initially and then with two maintenance doses of 2.

[Tooth extraction on diabetic patients].

Performing extractions on diabetic patients is a complicated problem, which is connected with the type of diabetes and the various complications related to this disease. The main concern is to avoid acute incidents hyper or sub-glycemic comas during the operation and to secure a smooth post- operational course, namely an undisturbed post- extracture healing. In this study, 80 diabetic patients who came for extractions to the escodental department were divided into two categories: patients suffering from diabetes type I and patients suffering from diabetes type II.

[Influence of tooth extraction on the CT level in plasma. Influence on the plasma Ca-P levels during the postextraction healing after CT administration].

The constant concentration of calcium ions (Ca2+) in the extracellular fluids can be maintained by two mechanisms; the local and the hormonal one. In the case of the local, a potential Ca2+ balance is achieved between the extracellular space on the one hand and the bones and intertine on the other hand, which may come to concentrations of 7 mg/100 ml. The complete settlement of the Ca2+ level up to the normal limits of 9-11 mg/100 ml of plasma, is achieved by the action of the hormonal mechanism.
