Abstract
Aim of research: To increase the resistance of teeth enamel in children with disorders of their formation by introduction of the complex of prophylactic arrangements using remineralizing preparation. Materials and methods. The object of research is the zones of injured enamel (on the background of hypoplasia) of permanent teeth. The subject is the level of general calcium and orthophosphates in acid biopsy materials of injured teeth enamel. Methods of research: the vital coloration of enamel, transillumination, acid biopsy of enamel, photometric, statistic. There was carried out the determination of level of calcium and orthophosphates in acid biopsy materials of injured enamel in 45 children, 6–12 years old with enamel hypoplasia. The group № 1 (21 persons) – children who underwent the complex of prophylactic arrangements that included recommendations as to the choice of means and subjects for oral cavity care and teaching the standard method of teeth brushing. The group № 2 (24 persons) – children, who additionally used remineralyzing cream on the water base with casein phosphopeptide – amorphous calcium phosphate (СРР-АСР) (Certificate on the state registration №10014/2010 of 03.12.2010). Results. In children with chronologic enamel hypoplasia was established the low level of calcium and orthophosphates in acid biopsy materials of injured enamel. Calcium/phosphorus (Са/Р) coefficient in examined groups № 1 and № 2 was 1,26±1,14 and 1,19±0,56, respectively. The high effectiveness of the offered complex of prophylactic arrangements (teaching the hygienic habits – group №1, additional use of remineralizing cream – group № 2) is proved by the growth of macroelements content in acid biopsy materials of injured enamel in examined children. The holding of prophylactic arrangements in children of the group № 2 using remineralizing cream, favored the more essential growth of level of calcium and orthophosphates in biopsy materials comparing with group of children № 1 (р=0,002 and р=0,03, respectively), and also reliably increased Са/Р coefficient (р=0,0005). Conclusions. Introduction of complex of prophylactic arrangements using remineralizing preparation in children with disorders of teeth formation favored the rise of enamel resistance as a result of growth of the level of calcium and orthophosphates in its mineral component.
Highlights
Prophylaxis of complications of teeth formation disorders is a topical problem of the modern child therapeutic dentistry
The teeth formation disorders including enamel hypoplasia are more than 9 % among diseases that lead to the premature destruction and extraction of teeth in children [1,2,3,4]
Enamel hypoplasia appears as a result of disturbance of mineral metabolism in the period of teeth formation and development and caries injuries hard tissues of already formed teeth, first of all leading to the destruction of falsely formed hard tissues [1]
Summary
Prophylaxis of complications of teeth formation disorders is a topical problem of the modern child therapeutic dentistry. According to the international index of dental diseases (IDC-D), enamel hypoplasia (К00.40) is assigned to the group “disorders of teeth formation” (К00.4) This injury of permanent teeth in children is a result of different endogenous and exogenous factors during the period of intrauterine development or first years of life [1]. Enamel hypoplasia appears as a result of disturbance of mineral metabolism in the period of teeth formation and development and caries injuries hard tissues of already formed teeth, first of all leading to the destruction of falsely formed hard tissues [1]. It is well-known, that teeth in the first months after cutting are most vulnerable to caries [7, 8]
