“…A significant prevalence of fissure caries in the children in the first years after the eruption of permanent teeth [5,6,7,8] requires an in-depth study of risk factors for its occurrence and methods of preventing the development of this pathology. In the development of caries, the composition and properties of the oral fluid are of great importance, since the oral fluid is a complex biochemical fluid that provides mineralization of the tooth tissues after their eruption [9,10,11,12]. Given this, it is important to study the mineralizing properties of oral fluid as a marker of the effectiveness of methods for the prevention of caries fissures of permanent teeth in the children.…”

“…According to a number of authors, the prevalence of the fissure caries in children in the 1 st and 2 nd years after the eruption of permanent teeth requires an in-depth study of the risk factors for its occurrence and methods of preventing the development of this pathology [5,6,7,8]. A number of studies have been conducted, which testify to the significant influence of the composition and properties of the oral fluid on the development of the carious process [9,10,11,12]. However, many questions remain open related to the study of the mineralizing properties of the oral fluid, as a marker of the effectiveness of methods of prevention of the fissure caries of permanent teeth in children.…”

The purpose of the study was to investigate the morphological properties of oral fluid in dynamics in the application of the developed set of measures for the prevention of fissure caries of the first permanent molars in children. Materials and methods. 62 children aged 6 years with fissure caries of the first permanent molars (main group) and 31 children without signs of carious lesions (control group) were examined. The study of the crystal formation of oral fluid was carried out according to the method of Leus P. A. (1977). The mineralizing potential of oral fluid was expressed as an average score depending on the types of crystals detected. Results and discussion. The analysis of the results of the study showed that 6 months after the start of preventive measures in the oral fluid of the children of the main group, a slight increase in type I crystals was noted in comparison with the initial data (40.18 ± 4.65% of cases, p>0.5), at the same time, the number of children, in whom type III crystals were observed, decreased in the main group (16.45 ± 2.32%, p>0.5), and increased in the control group (19.32 ± 2.47% of cases, p>0.5) in comparison with the initial data. After two years of observation, in the children of the main group, type I crystals were most often detected in the oral fluid (48.41 ± 4.23% of cases), in the children of the control group, on the contrary, the number of children with this type of crystals decreased and was almost one and a half times less than among children of the main group (p<0.05). On the other hand, the number of children in the control group, in whom type III crystals were detected, was two times higher than among children in the main group (22.34 ± 2.87% and 11.51 ± 2.56% of cases, respectively, p<0.05). Conclusion. It was established that in children who received a complex of preventive measures, 6 months after the implementation of preventive measures, the mineralizing potential of oral fluid was, on average, 2.73 ± 0.07 points, which is slightly higher compared to the fissure detected at the beginning of caries prevention (2.57 ± 0.12 points respectively, p>0.05). In the children of the control group, the mineralizing potential of oral fluid changed less noticeably (from 2.64 ± 0.11 points at the beginning of observation to 2.66 ± 0.11 points, p>0.5). After two years of observation, it was found that in the main group the mineralizing potential of oral fluid continued to increase, while in the children of the control group it decreased and reached almost the initial level (2.65 ± 0.07 points in the second year of observation and 2.64 ± 0.08 points at the beginning, p>0.05). Thus, it can be concluded that the proposed measures are quite effective

Physical Properties of Oral Liquid in Children With Malocclusion and Different Enamel Resistance

2023

One of the factors in the development of dental caries in children with malocclusion is the insufficient enamel mineralization in different age periods, that is, its resistance is reduced. An important role in the formation of enamel resistance is played by the oral fluid, in particular its physical properties, mineralization potential and protective mechanisms. Fluctuations in the pH of the oral fluid significantly depend on the hygienic condition of the oral cavity and the nature of the food. At the same time, the possibility of access of mineral elements to the surface of the enamel significantly worsens in case of increased viscosity and decreased rate of saliva secretion of oral fluid. This, in turn, contributes to the reduction of diffusion processes in tooth enamel and the creation of conditions for the development of enamel demineralization. The purpose of the investigation is to study the peculiarities of the physical properties of oral fluid in children with malocclusion at different levels of enamel resistance. Research methods. It was found that the concentration of hydrogen ions in the oral fluid of the examined children with malocclusion is, on average, 6.67±0.05 units, and the viscosity and rate of saliva secretion is 2.32±0.06 rel. unit and 0.43±0.02 ml/min. In children with anomalies of individual teeth, the average pH value of the oral fluid is 6.93±0.08 units, while with anomalies of the dental arches and occlusion, there is a shift of the pH to the acidic side. In 12and 15-year-old children with anomalies of occlusion and caries-resistant enamel, the pH of the oral fluid is higher by 7.46% and 7.85%, respectively, compared to children with conditional-resistant and caries-susceptible enamel, the viscosity of the oral fluid is lower by 40.49% and 33.48%, respectively, and the rate of salivation is higher by 26.19% and 22.92%, which changes the function of oral fluid in the latter towards the demineralizing solution. Conclusions. Thus, the detected changes in the physical properties of the oral fluid in children with malocclusion and reduced enamel resistance may be important in the pathogenesis of dental caries development, as in such conditions the function of the oral fluid changes from mineralizing to demineralizing.
