Success of dental implants placed in intraoral block bone grafts.

Background: The purpose of this study was to evaluate the survival and success of dental implants placed in alveolar bone following augmentation using intraoral block bone grafts.

Methods: A consecutive retrospective study was conducted on patients who had onlay bone grafts for vertical or horizontal augmentations followed by dental implantation from 1999 to 2001. Files of 50 healthy patients who received 129 implants in augmented sites were reviewed.

Impact of smoking on marginal bone loss.

Purpose: To compare marginal implant bone loss (MBL), survival, and radiographic evidence of success of dental implants among smokers and nonsmokers.

Materials And Methods: Consecutive records of 161 patients (aged 23 to 89 years, mean 57 years) treated with a total of 646 implants between the years 1995 and 1998 were examined. Patients were divided into 3 groups: nonsmokers, moderate smokers, and heavy smokers.

Quality of life following parotidectomy for malignant and benign disease.

Parotidectomy is performed for benign or malignant tumors and for selected benign inflammatory and autoimmune conditions. Possible associated complications include facial nerve paralysis, pain, loss of sensation, gustatory sweating, and facial scarring. Global quality of life in patients undergoing parotidectomy has not been reported.

[Silicone granuloma of the lip].

Silicone is considered a biocompatible material, and therefore has many applications in medicine. It can be used in a liquid form for subcutaneous injection, in gel form for implants, and in a solid state for prostheses, hemodialysis tubing, etc. The use of injectable liquid silicone for tissue augmentation is widespread, but there are many reports of side effects, some severe and debilitating such as the granulomatous reaction.

Histomorphologic and morphometric changes in minor salivary glands of the rat tongue during 4-nitroquinoline-1-oxide-induced carcinogenesis.

4-Nitroqinoline-1-Oxide (4NQO)-induced tongue carcinogenesis in rats is considered to be a preferred model for study of oral squamous cell carcinoma. Aim of study was to investigate histomorphologic and morphometric 4NQO-induced changes in tongue minor salivary glands. Histopathological examinations of serous and mucous acini and ducts of tongue salivary glands of 26 Wistar-derived rats were performed after 14 (T(1)), 22 (T(2)) and 28 (T(3)) weeks of 0.

The effect of bacterial endotoxin on the early tensile strength of healing surgical wounds.

Wound healing in the oral cavity occurs in a bacteria-rich environment, which may affect its outcome. Furthermore, it takes place where forces are frequently applied to the healing tissue. The effect of bacterial endotoxin on the development of tensile strength in healing wounds was studied using surgical skin wounds in rats as a model.
