[EPIDEMIOLOGY OF DENTAL CARIES, DENTAL STATUS AND CORRECTION PROSPECTS IN SCHOOL CHILDREN OF ADJARA REGION KOBULETI AND KHELVACHAURI MUNICIPALITIES].

The epidemiological research was conducted among school children of 6-7, 12, 15 ages (According to the WHO nomenclature) in the municipalities of Kobuleti and Khelvachauri of Ajara region in order to study the spread of major dental diseases and determine further prophylactic measures. The research involved 246 children, of whom 129 were residents of Kobuleti and 117 residents of Khelvachauri. Studies have shown that in all age groups the level of caries distribution is high; the median intensity index is also high in all age groups compared to the median indexes established for residents of Georgia.

Benign osteoblastoma of the mandible in a 12-year-old female: A case report.

Benign osteoblastoma refers to a benign tumor of the bone. Osteoblastoma most commonly affects the vertebrae and long tubular bones, however, in rare cases is observed in the facial bones. The current study presents the case of a 12-year-old female patient with a tumor in the mandibular body.

Prevalence and intensity of dentition defects and secondary deformations in the population of 15-40 age group.

Partial secondary adentia together with caries and parodont diseases is among the most widespread diseases of dentofacial system, correlated, in addition, to the number of lost teeth, with the age. Result in speech and chewing functions' disorders, change of face shape, esthetic and psychosocial inferiority, pathologies of digestive and other systems, formation of the chronic infection areas, changes of reactivity etc,. Improvement of the methods of prevention and treatment of the above diseases is one of the most significant problems in the dentistry.

The role of human papillomavirus in oral squamous cell carcinoma (review).

This article reviews the role of human papilloma virus (HPV) in oral squamous cell carcinomas (OSCCs), including the history, epidemiology, risk factors, molecular biology of oral HPV infection, and the prognostic role of HPV detection in patients with OSCC. The review showed that HPV is involved in the pathogenesis OSCCs; it determines the prognosis and modulates treatment response. Studies show a link between HPV and mouth cavity carcinoma: HPV preferentially infects the pre-cancer cells of the oropharynx; HPV prevalence is higher in pre-cancerous and cancerous oropharyngeal lesions.

Adsorption study of alkyl-silicas and methylsiloxy-silicas.

We report the synthesis and adsorption study of the lyophobic porous silicas. Four adsorbents were prepared and tested: (1) octyl-silica, (2) hexadecyl-silica, (3) bis(trimethylsiloxy)-silica, and (4) oligo(dimethylsiloxane)-silica. Octyl- and hexadecyl-silicas were prepared via the reaction of silica with (CH3)2NSi(CH3)2CnH(2n+1) (n=8 and 16), the reactions were carried under the optimized conditions yielding high bonding densities of alkyl groups approximately 2.
