RESUMO
The objective of the present study was to analyze histomorphometrically the biological behavior of microgranular hydroxylapatite (HA 40), and tricalcium phosphate (TCP) implanted in the dental alveolus of rats. All three materials retarded alveolar repair when compared to controls, since less bone was formed during all periods of study. Nevertheless, MIC and TCP showed higher compatibility than HA 40.

The authors report 4 cases of accidental dislodgement of teeth to adjacent anatomical areas during extraction. The causes and their prevention are discussed and solutions for the problem are suggested.

The incorporation of alanine C14 in protein synthesis was analyzed in recently formed alveolar tissue after tooth extraction in partially-pancreatectomized diabetic rats. The incorporation of alanine C14 was higher in diabetic animals than in treated diabetic and control groups. The results can be explained by a delay in bone tissue repair.

The aim of the present study was to evaluate and discuss the indications of different splinting methods used in surgical procedures. It was proposed that the use of "semirigid" fixation method could be a more valuable technique in autogenous transplants and dental reimplants.

The pain and swelling resulting from impacted lower third molars surgery were investigated in 18 patients. A descriptive pain scale method and paracetamol consumption were used for pain evaluation. The face bow nine-pointers was used for swelling measurements. The results showed that the pain peaked at 3 post-operative hours when it was considered of moderate intensity and decreased considerably in the following periods. Swelling peaked between 32 and 48 hours after surgery, and thereafter, a tendency towards regression was observed. No corelationship was found between pain symptoms and swelling.
