SPECIFIC FEATURES OF DENTAL STATUS OF CHILDREN WITH CONGENITAL LIP AND PALATE IN A REGION WITH PETROCHEMICAL ECOTOXICANTS

Abstract

Subject. Dental examination and identification of the features of the dental status of children with congenital cleft lip and palate, born and living in the region with industrial ecotoxicants. Objectives. To study the dental morbidity in children with congenital cleft lip and palate living in a region with industrial ecotoxicants, compare the data with a group of children with congenital cleft lip and palate from an ecologically safe region. Methods. The article presents the results of a dental examination of 195 children with congenital cleft lip and palate, including 108 children aged 3 years, 87 children aged 6 years. Children were divided into two groups depending on the place of birth and residence: 113 children were born and lived in regions with a developed petrochemical industry, 82 children from relatively ecologically safe regions. In the examined children, the prevalence and intensity of dental caries, malformations of hard dental tissues, periodontal diseases, dentoalveolar anomalies, and the hygienic state of the oral cavity were assessed. To determine the intensity of dental caries in children of 3 years old, the index "KPU" was used, in children of 6 years old - the index "KPU+kp". The hygienic state of the oral cavity was assessed by the Fedorov-Volodkina index (1968), the periodontal condition in children of 6 years old was assessed by the KPI index (Leus P.A., 1988). Results. Our data indicate that children from regions with the petrochemical industry have higher rates of dental caries intensity in the age groups of 3 and 6 years, there is a decrease in the resistance of the tooth enamel, and periodontal diseases are more common. Conclusions. The results of the study made it possible to obtain clinical and dental data characterizing the negative impact of industrial petrochemical ecotoxicants on the condition of the dentition in children with congenital cleft lip and palate, which is the rationale for the development of methods for optimizing and increasing the effectiveness of therapeutic and prophylactic measures in this group of patients.
