Caries incidence was assessed in pregnant women in 1998, 2003 an 2008 showing the values to be stable. DMF was almost the same in 1998 and 2003, but in 2008 the rate of "F" (filled) element was significantly higher thus confirming growth in motivation for dental treatment after introduction of private dental practices.

Caries incidence was assessed in young (15-17 years) and mature (30-34 years) nulliparous pregnant. In young women the incidence was 1.62 +/- 0.16, while in mature pregnant--1.38 +/- 0.17. This values are significantly higher than in non-pregnant women of the same age: 0.48 +/- 0.09 and 0.24 +/- 0.08, correspondently.

Results of oral cavity sanation performed upon 2366 pregnants during years 2003-2006 in the city of Derbent were studied. It was established that the need in caries and its complications treatment was equal to 78.91+/-0.84% of all pregnants. Due to the study of sanation refusal reasons and individually oriented educational work it was possible to reduce the number of unfavourable decisions (to refuse from sanation) from 15.02+/-1.77% in 2003 to 8.91+/-1.21% in 2006. Due to the reduction of this number and the ART-technique of caries treatment implementation in women with heavy pregnancy running the following sanation indeces improved: the portion of sanated pregnants from all needed in such procedure increased from 77.59+/-2.07% in 2003 to 87.45+/-1.41% in 2006, the number of filled carious lesions increased from 74.13+/-1.16% to 88.18+/-1.86% in 2006, the portion of extracted teeth from those intended for extraction 0- from 75.90+/-2.71% in 2003 to 89.17+/-1.75% in 2006.

Examination of the oral status of 664 pregnant women showed that from 77.12 +/- 3.90% at the age of 17-19 years to 100% at the age of 35-39 years were in need of treatment and removal of teeth. An average of 2.46 tooth per woman were to be filled and every other woman was in need of tooth removal. The quality of oral hygiene was poor in the examined patients, the Fedorov-Volodkina index varying from 2.2 +/- 0.05 to 2.6 +/- 0.1.

The author suggests repair of the front teeth after crown-root fractures making use of the remaining crown. Due to precise coincidence of the fracture surfaces of both fragments of the tooth and fixation with a cast pin and composite materials, good results were attained.

Late results of treatment of the crown and root fractures of masticatory teeth are assessed in 23 patients. The method of treatment consisted in provisional fixation of a fragment with wire for further permanent fixation by special filling and a metal crown. The method is simple, its results are good, and it is recommended for practical dentistry.

Analysis of 724 case histories over many years permitted the author to distinguish the seasonal regularities in the development of various stomatological diseases, differing by the etiology and pathogenesis: furuncles on the face, mandibular fractures, and lymphadenitis of the maxillofacial area and neck. Under the climatic conditions of the town of Derbent a seasonal rise in the incidence of furuncles of the face is observed in July, August, and September, that of mandibular fractures in May, and July, and of lymphadenitis in January, February, July, and August.

The study into the causes underlying nonspecific lymphadenitis (NSL) and adenophlegmons of the maxillofacial region and the neck (AF) revealed a great variety of etiological factors and primary infectious foci in these diseases. Of 204 children admitted to hospital of the city of Derbent, odontogenic genesis of the disease was determined in 27.45% of cases; dermatogenic, stomatogenic in 23.04 and 12.74% of cases, respectively. ENT and systemic diseases were responsible for NSL and AF in 13.23 and 3.43% of cases. The cause remained unclear in 20.09% of patients. NSL and AF occurred most frequently in the coldest (January, February) and the hottest (July, August) months of the year.

A congenital myoblastoma in a newborn boy is described, developing on the maxillary gingiva. Histological examination showed it to be a myoma of myoblasts, Abrikosov's tumor. Examination after 2 years did not reveal a relapse of the tumor.

Application of 2% sodium fluoride solution in children aged 10 to 11 result in a noticeable reduction of caries development: by 50% during the first year, by 43.18% during the second, by 46.05% during the third, and by 42.85% during the fourth year of such treatment. Caries-preventive effect persists for only 12 months after two-year applications, caries reduction being 35.21% in the first year and only 5.7% in the second year after the treatment discontinuation.

Analysis of the results of treatment of 150 alveolitis patients has demonstrated the advantages of the method using iruxol ointment (75 patients) as against the routine one (reference group--75 patients). Therapy with this ointment resulted in complete arrest of the painful syndrome in 2.11 +/- 0.15 days, whereas in the reference group it was attained in but 5.40 +/- 0.18 days. The temperature reaction normalized in all the test group patients within 3 days, whereas in the reference group such results were attained in only 74.36% of the patients. Inflammatory symptoms in the paramaxillary soft tissues were liquidated with iruxol ointment in 5.96 +/- 0.14 days, whereas in routine therapy this was observed in only 7.46 +/- 0.18 days.

Analysis of the results of 8019 operations for removal of teeth, carried out within 5 years by one physician under the same conditions, has shown that alveolitis developed in 1.87 +/- 0.15% of cases, on an average. The risk of alveolitis was found the highest from December to March and the lowest from June to September, as evidenced by estimation of the index of the seasonal fluctuations in the morbidity (a total of 120 to 140 teeth were removed within a month, on an average).

The efficacy of therapy for uncomplicated caries and of anticaries fluoridation in relation to seasonal fluctuation in caries incidence was studied in 405 children in the town of Derbent. The efficacy of therapy was found the highest if carried out soon after the major wave of caries development. A close relationship was revealed between the efficacy of anticaries fluoridation and the season when this procedure was carried out. Fluor treatment before the principal wave of caries incidence reduced it by 47.05%, whereas in spring this treatment brought about but a 3.84% reduction of caries incidence.
