Reported in the paper are data on 45 patients with mucoepidermoid carcinoma (MEC) of the admaxillary gland (stage 1-9, stage II - 15, stage III - 14, and stage IV - 7). The clinical course combined with morphological findings is of primary importance in the MEC diagnosis. The significance of aspiration biopsy, ultrasound examination, computer tomography, magneto-resonance computer tomography and sialography etc. is evaluated. Incision biopsy is admissible within the diagnosis in complicated cases. Prognostication of MEC primarily depends on a disease stage

A clinical-and-immunological study was undertaken in patients with chronic destructive periodontosis (CDP), which proves it as feasible to discriminate between the below categories: 1. CDP with affection of no more than 2 teeth; 2. Multiple CDP; 3. CDP concomitant with other pathologies; and 4. CDP as an odontogenic focus triggering focal diseases. Different disorders of general immunity were established; they ranged from compensatory changes to chronic endogenous intoxication and depended directly on a type of chronic periodontosis and on its signs described by us. Chronic periodontosis leads to suppression and misbalance of both cellular and humoral local immunological reactions. Multiple CDP was found to result in secondary immune insufficiency, which must be corrected.

The influence produced by dental treatment on the condition of the dentomaxillary system and on the general status was studied in 54 patients aged 18 to 80. Disorders related with the correct closure of jaws resulting from dental treatment procedures were detected; such disorders led to severe functional malfunctions of the dentomaxillary system. The reasons of violations of dental technologies, errors permitted in treatment and their relation with clinical signs of complications were thoroughly examined, which led to defining a diversity of clinical forms of complications with a common patho- genesis - incorrect closure of teeth at rest and at load. On the basis of it, it was concluded that clinical symptoms of malfunctions in closure of teeth share many common pathogenetic features, which can be referred to as the syndrome of "traumatic dentomaxillary occlusion ".
