A method for predicting the development of caries in permanent teeth

 

(57) Abstract:

The invention relates to medicine, namely to dentistry and can be used when carrying out activities for the prevention of dental caries. Conduct regular preventive dental examinations of the oral cavity in children aged 2 to 6 years before erupting first permanent molars. Upon detection of caries on the second milk molar aged 2 to 6 years predicted the defeat of the decay of the first permanent molar. The method allows for earlier prediction of caries in permanent teeth based on the analysis of caries of deciduous. table 1.

The invention relates to medicine, namely to dentistry and can be used when carrying out activities for the prevention of dental caries.

There is a method of prediction of dental caries, which consists in conducting periodic epidemiological surveys in age from 3 to 15.5 years. The growth of caries in this age period determine the probability of dental caries of permanent teeth [3].

The disadvantage of this method is the lag prediction time, during which preventive measures in the form of good nutrition, hygiene is a scale-based analysis of caries of deciduous. The task carried out due to the fact that they are carrying out a study of caries-fifths of teeth and localization determine the probability of occurrence of caries in first permanent molars. On the basis of data on the morphology of the first permanent molar (16,36), which in 100% of cases corresponds to the morphology of the second deciduous tooth (55,75). The eruption of the permanent generation begins with the appearance of the first permanent molar. According to dentists [2], sixth, seventh and eighth teeth are permanent, and some biologists believe these milk teeth, late on the timing of the eruption [4]. A. Andronescu [1] indicates that “second milk molar tooth similar to large permanent molars”.

Were studied 217 models of the teeth of the upper jaw of children aged six to eleven years. When studying odontologica signs dentition was found that the presence of the tubercle of Carabelli on the second dairy and first permanent molars of both jaws depends on the evolutionary-reducing transformations in the milk and permanent dentition in children. The study revealed that the shape of the coronal part of the first permanent molar in 100% of cases, similar to the form of the second milk molar outside dependence, what evolutionary transformation acting not only on the teeth permanent teeth, but the teeth in primary dentition. Due to the fact that in the process of embryogenesis primary teeth and first permanent molars are laid and mineralizable at the same time, therefore, in the event of violations of mineralization in the second milk molar of similar violations of mineralization occur in the first permanent molar. This can be interpreted as the sixth, seventh and eighth teeth of the permanent dentition are a continuation of the milk dentition, functioning in adulthood as constants.

The table presents data on the frequency of occurrence of caries in the second milk (55) and the first permanent molar (16).

We held individual study of localization on the second milk molar 150 children aged 2 to 6 years and localization on the first permanent molar from the moment of the eruption during the year. We found that children with caries second milk molar in 98.6% of registered caries of the first permanent molar. If the child on the second milk molar was missing tooth decay, it was not determined on the first permanent molar in 100%.

Therefore, the em it is possible to predict the defeat of the decay of the first permanent molar. The relationship of the shape of the tooth crown and the recording frequency of caries second dairy and first permanent molars has a significant relationship and does not depend on the sex of the individual.

The method is as follows. Conduct inspection of the oral cavity of children aged two to six years before the eruption of the first permanent molar. Upon detection of caries and identification of carious lesions on the second milk molar, based on earlier morphological studies, we can determine that caries will develop in the first permanent molar.

Regular and timely inspections of the mouth of the child at an early age to prevent the development of caries in first permanent molars and conduct hygiene measures for the prevention of caries in permanent teeth in the early stages of its development, for example at the stage of spots.

New technical solution of the present invention is the prediction of caries in permanent teeth based on the development of caries of deciduous.

New clinical effect is in the early implementation of preventive measures during the eruption of the permanent the ASTA doctors hygienists about the possibility of manifestation of the carious process in permanent teeth for their timely treatment in the early stages.

SUBSTANCE: at patient's hospitalization one should gather the data of clinical and laboratory values: on the type of chemical substance, patient's age, data of clinical survey and laboratory values: body temperature, the presence or absence of dysphonia, oliguria being below 30 ml/h, hemoglobinuria, erythrocytic hemolysis, exotoxic shock, glucose level in blood, fibrinogen and creatinine concentration in blood serum, general bilirubin, prothrombin index (PTI), Ph-plasma, the state of blood clotting system. The state of every sign should be evaluated in points to be then summed up and at exceeding the sum of points being above "+20" one should predict unfavorable result. At the sum of "-13" prediction should be stated upon as favorable and at "-13" up to "+20" - prediction is considered to be doubtful.

EFFECT: higher accuracy of prediction.

SUBSTANCE: method involves evaluating prognostic signs and calculating their prognostic weight. Consciousness disorders and diagnosis set at prehospital stage are used as the prognostic signs. Calculations are carried out from formula: lethal outcome %= -15.99+19.1•C+14.7•DS-2.79•C•DS, where C is the ranged consciousness disorder degree, DS is the diagnosis set prehospital stage. The higher is the value, the higher is lethal outcome probability.

SUBSTANCE: the present innovation deals with differential diagnostics of prostatic cancer and other prostatic diseases at the stage of primary inspection. The method includes the detection of PCA and calculation of probability coefficient for prostatic cancer (PCC) by the following formula: where e - the foundation of natural logarithm (e=2.718…), PCA - the level of total blood PCA in ng/ml, V - patient's age in years. At PCC value being above 0.2 one should diagnose prostatic cancer and to establish final diagnosis one should perform polyfocal prostatic biopsy. The method enables to increase accuracy of diagnostics at decreased number of unjustified prostatic biopsies.

SUBSTANCE: method involves measuring radio signals and low frequency spectra of signals emitted by oral cavity organs and tissues in maxillofacial area. Decoding and comparison of the spectra to healthy organs and tissues spectra is carried out. Then, modulated information signals in infra-low frequency bandwidth corresponding to healthy organs and tissues signals are applied. Low frequency radio signals and spectra are measured. Treatment with modulated signals in infra-low frequency bandwidth is applied directly to organ or its location zone via skin.

EFFECT: enhanced effectiveness in diagnosing and treating oral cavity organs and tissues in maxillofacial area.
