In connection with the variability and as a consequence of the poor diagnostic value of the external (planimetric) parameters of the palm traces, the new system of absolute and relative dimensional attributes based on the stable palmoglyphic reference points is considered. The purpose of the present study was the search for the new biological markers of biological age. The material for the study consisted of the palm prints obtained from 180 men and 120 women of the Caucasoid stock at the age from 16 to 80 years. The use of the descriptive statistics methods yielded the basic statistical characteristics of the traits being investigated and revealed the limits of their variability in the groups of men and women belonging to the age groups from 16 to 29 and from 30 to 80 years. The method of threshold values made it possible to identify 13 attributes the excess of which allows, with the probability of no less than 0.95, to perform diagnostics of the age group of an unknown subject.
Статья посвящена исследованию взаимосвязи неизменяющихся и изменяющихся дерматоглифических признаков ладоней с длиной тела взрослого человека с учетом его половой принадлежности. Материал исследования: дерматоглифические карты ладоней 208 мужчин и 102 женщин в возрасте от 17 до 83 лет (центральные европеоиды). Методы исследования: получение отпечатков ладоней с помощью черной типографской краски на белой бумаге путем оттиска, распознавание дерматоглифических признаков по методике H. Cummins, Ch. Midlo (1943), описательная математико-статистическая характеристика дерматоглифических признаков, корреляционный анализ. Установлено, что для высокорослых (от 180 см) характерна положительная узорность в области тенара и во II межпальцевой подушечке, а также наличие проксимального или дистального осевого трирадиуса. В противоположность этому для низкорослых (до 160 см) характерна отрицательная узорность и наличие промежуточного осевого трирадиуса. Кратность различия частот встречаемости качественных признаков в различных ростовых группах составляет от 2 до 5 (p<0,05). Среди количественных признаков наибольшую корреляцию с длиной тела имеют размеры ладонного отпечатка (0,66), плотность папиллярных гребней (-0,30) и гребневой счет (0,24). Взаимосвязь дерматоглифических признаков ладоней с длиной тела взрослого человека наблюдается как у изменяющихся (линейные размеры, плотность гребней), так и у неизменяющихся признаков (тип узора, осевые трирадиусы, гребневой счет), что подтверждает многофакторную природу исследованного свойства личности и объясняет трудности, с которыми сталкиваются ученые-разработчики при создании экспертных методик по определению роста человека на основе ограниченного набора признаков. Сделан вывод о том, что высокоточные диагностические методики могут быть получены только при учете всех групп дерматоглифических признаков. Ключевые слова: дерматоглифика, рост, ладонь, отпечатки, папиллярный узор, пол.
Aim. Evaluation of the effective preventive methods of dental caries in children with dentoalveolar anomalies. Methods. Orthodontic treatment was received by 50 children aged 12-14 years with dentoalveolar anomalies who were treated by an orthodontist using ligature bracket and who had a compensated form of dental caries before the beginning of the hardware treatment. In the first group of children (control, 25 subjects) professional oral hygiene twice a year was followed by the coating of all teeth with fluoride. Children of the second group (25 subjects) after professional oral hygiene twice a year had their teeth covered with tooth enamel around brackets with Clinpro XT Varnish (3M ESPE) material containing fluorine, calcium and phosphate compounds. Dental examination every three months included assessment of oral hygiene and the state of the gums, the presence of carious defects, fillings and removed teeth, followed by the calculation of the main dental indices. Results. On the basis of studies of the dental status in children undergoing orthodontic treatment using brackets, the main dental indices such as DCF (decay/missing/filled), complex periodontal index, papillary-marginal-alveolar index were characterized at the stages of treatment. The analysis of the recorded values was performed in the comparison groups for each research method and the main statistically significant differences were identified. The study revealed that children from group 2 had positive dynamics of the state of periodontium within 18 months: the value of papillary-marginal-alveolar index among children from group 2 decreased by 5.4 times, the value of complex periodontal index decreased by 3.5 times. Children from group 2 had a significantly lower incidence of caries compared to the control group after 18 months of remineralizing therapy: the increase of complex periodontal index among children receiving orthodontic treatment with Clinpro XT Varnish coverage twice a year was only 1.42±0.16, incidence of caries of teeth surface reduced by 55%. Conclusion. On the basis of these studies, a comparative characteristics of the dental indices was performed at the stages of treatment using the brackets, depending on the used primary preventive measures; dental status of children at the stages of orthodontic treatment have their features: special oral hygiene tools should be guided by hygiene indices and complemented by remineralizing drugs.
