Morphology of neuroendocrineimmune system of jejunum in early postnatal ontogenesis
Abstract: In this study we compared research children's with developed educational preventative dental work prepared for use of fixed orthodontic appliances, aimed at improving the sanitary-hygienic knowledge of children, teachers and parents, to normalize the hygienic condition of the mouth and reduce the prevalence and the intensity of dental caries.
Morphology of neuroendocrineimmune system of jejunum in early postnatal ontogenesis
Keywords: Dental caries, fixed orthodontic appliances, index OHI-S, index «Kny» (k- carious teeth, n- dental filling material, y- extracted teeth), and index Fedorov-Volodkina.
Introduction
Over the last decade, there was a significant reduction in the prevalence of dental caries in children and adolescents [2; 3]. The reasons for this are varied, but the most significant are reduced consumption of sugars, improving the quality of care for oral and dental hygiene, the use of fluoride-containing toothpaste, improving the organization of dental services [8].
In domestic and foreign sources of information are widely considered the organization and evaluation of professional activities aimed at the prevention of dental diseases [1; 4].
The most important and the weakest link in the implementation of the prevention of major dental diseases is hygienic education of the population, dental educational work and training of oral hygiene [5; 6; 7].
Purpose of the study:
Basis for the use of the system of prevention of hard and soft oral tissues to caries in children as criteria for assessing the effectiveness of preventive measures for preparing to use of fixed orthodontic appliances.
Materials and methods
At the Department of Pediatric Otorhinolaryngology and children's dentistry Tashkent Pediatric Medical Institute developed educational preventative dental work prepared for use of fixed orthodontic appliances, aimed at improving the sanitary-hygienic knowledge of children, teachers and parents, to normalize the hygienic condition of the mouth and reduce the prevalence and the intensity of dental caries in children.
Educational preventive dental program has been implemented for 1 year based on the student clinics number 56. The program involved students in the groups aged 7-9 years.
To analyze the impact of preventive work the children were divided into 2 groups: Group 1-25 children 7-9 years old and group 2-30 children 10-12 years.
Furthermore, for comparative analysis and evaluation of the implementation of dental preventive work we performed dental examination of 20 children aged 7-9 years enrolled in educational institutions ofYunus-abad district, Tashkent, Uzbekistan, among whom any preventive measures and programs have not been conducted. For a comparative analysis, the children were divided into 2 groups: control group 1-10 children of 7-9 years, the control group 2-10 children of 10-12 years.
Results
Dental survey of children of age 7-9 prior to the implementation of dental preventive work has revealed the following. The prevalence of dental caries in surveyed children 10-12 years was 73.6%, while the index of the intensity of the "Kn» (k- carious teeth, n-dental filling material) 3.35 + 0.63. In the structure of the index, «Kn» noted the predominance of the component «K» — 2.67 + 0.56, the number of seal teeth time was 0.68 ± 0.15.
Analysis of the hygienic condition of the mouth of surveyed children showed a satisfactory level of hygiene, the average value of the index according to Fedorov-Volodkina was 1.83 ± 0.41.
In the group of 10-12 years children, the prevalence of dental caries reaches 81.32%, with the defeat of caries in permanent teeth in this age group was observed in 42.31% of children. The intensity of caries of temporary teeth on the index of «Kn» equal to 2.32 + 0.49, in the structure of the index number of carious teeth is 1.16 + 0.28, the number of temporary sealed teeth — 1.18
+ 0.25. The intensity of caries in permanent teeth among children 10-12 years of age was 0.9 + 0.196, noted the predominance of the component «K» in the structure of the index «Kny» — 0.53 0.12, a component of «n» is 0.42 +0, 09, the value of the component «y» trivial and 0.01 ± 0.002.
Analysis of the hygienic condition of the mouth of children of 10-12 years showed that the average value ofhygienic index OHI-S was 1.91, which corresponds to an unsatisfactory level of oral hygiene.
Primary dental examination of the control group showed the same level of hygienic condition of the oral cavity and the degree of caries of temporary and permanent teeth.
The survey found that the prevalence of dental caries in surveyed children of control group 1 (7-9 years) was 72.5%, while the index of the intensity ofthe «Kn» 3.05 ± 0.63. In the structure of the index, «Kn» noted the predominance of the component «K» — 2.32 + 0.57, the number of sealed temporary teeth was 0.73 ± 0.11. At the same time, there was no evidence of cases of permanent teeth caries in this age group.
Analysis of the hygienic condition of the mouth examined children in the control group 1 showed satisfactory level of hygiene, the average value of the index according to Fedorov — Volodkina was 1.78-0.43.
In the second control group of children (10-12 years) prevalence of dental caries reaches 82.5%, while decayed permanent teeth in this age group was observed in 42.5% of children. The intensity of caries of temporary teeth according to the index of «Kn» is equal to 2.55 + 0.63, in the structure of the index number of carious teeth was 1.26 0.31, the number of temporary sealed teeth — 1.29 + 0.29. The intensity of caries in permanent teeth in this group was 1.01 + 0.19, noted the predominance of the component «K» in the structure of the index «Kny» (k- carious teeth, n- dental filling material, y- extracted teeth) — 0.67 + 0.21, component «n» is 0.34 0.08, there was no ablated permanent tooth (component «y» is equal to 0).
Analysis of the hygienic condition of the oral cavity of the second control group of children (10-12 years) revealed that the average value of hygienic index OHI-S was 1.93 + 0.45, corresponding to unsatisfactory level of oral hygiene.
Repeated dental survey conducted in 1 year in children aged 7-9 years in the observed group was improvement in oral hygiene from fair to good level (the difference amounted to 21.86%), while the control group of the same age level of hygiene remained at a satisfactory level and even there was a slight increase in the index of Fedorov-Volodkina, reflecting the worsening of oral hygiene (the difference amounted to 1.69%).
In the group of 10-12 years, children who participated in the prevention program (group 2) noted the change in the index of Hygiene OHI-S from the poor to a satisfactory level (the difference amounted to 30.89%), in the control group of children of 10-12 years hygiene remains unsatisfactory despite a slight improvement (the difference amounted to 1.69%).
Discussion
When analyzing the changes in the intensity of caries of temporary and permanent teeth in children and control groups of children participating in the program of prevention after 1 year of observation it was found an increase in the studied parameters, but the degree of increase was different.
The data indicate the effectiveness of preventive dental work carried out among groups of children 1 and 2. The improvement of hygienic conditions: of group 1 children from fair to good level and children of groups 2 with unsatisfactory to a satisfactory level ofhygiene.
It should be noted that in children of groups 1 and 2 was not carried out routine oral hygiene in hospitals, changing the structure of the index "Kn» and «Kny» has been achieved by increasing the motivation of parents to preserve the health of the oral cavity and a systematic appeal to dentists.
The data indicates the effectiveness of preventive dental work among children aged 7-9 years and in the group 10-12 years.
Conclusions
As a result of the preventive dental work for preparation for use offixed orthodontic appliances in children of age 3-6 and 7-10 years had marked increasing of levels of sanitary-hygienic knowledge, improvement in the index of oral hygiene (at 21.86% and 30.89%) and changing the structure of the index "Kn» and «Kny» by increasing the number of sealed, and reducing the number of carious teeth (in the group 1 component «K» decreased by 36.70%, and «n» has increased by 198.53%, in the group 2 component «K» has decreased by 28.30% and the component «n» increased by 80.95%).
