Implementing the Questionnaire for Epidemiological Surveillance, general distribution of anomalies could be presented by the Anomaly index (AI), which dictates the introduction of a standardized questionnaire for epidemiological screening, which would preclude ambiguousness and the differences between the epidemiological research data would be cut to the minimum.

Differences identified in craniofacial parameters in relation to Bolton standards show that one should carefully consider the risk of altering facial esthetics of patients from Vojvodina with extraction treatment. Whenever possible, give priority to early non-extraction treatment, in order to reach the best possible end-result within the given facial type, preserving facial esthetics.

Analysis of the morphological characteristics of the maxilla in mouth breathing children showed characteristics also present in persons with marked clinical features of OSA syndrome, such as a narrow maxilla, insufficient apical base length, as well as the reduced angle of the palatal plane angle to the anterior cranial base. All these suggest a possible increased risk of developing OSA syndrome in children's later age.

Introduction. Tooth extractions, particularly of the permanent teeth, lead to different and numerous consequences. It is known that the incidence of caries and the incidence of premature extractions are the highest with the first permanent molars. The aims of this study were to examine the possibility of determining the relations between the translatory movement and the agonist teeth inclination depending on the time of the performed extraction, as well as on the temporal distance from the moment of extracting the first permanent molar to the moment of analyzing the changes. Material and Methods. The study was performed on the sample of 185 subjects, their age ranging from 11 to 26 years (X=14) with early (by the age of 11 years) and late performed extraction of the first permanent molars in the maxilla and mandible and determined class I of occlusal relationship. Results. The relation, expressed by the mathematical expression, between the translatory movement and tooth inclination has been confirmed, but only in case of late extractions. As for early extractions, the obtained results of the correlation coefficient value showed no relations between translatory movement and tooth inclination. Conclusion. The relation between translatory movement and teeth inclination (the second premolars and the second permanent molars) expressed by the mathematical expression has been confirmed by the given values of the correlation coefficient, but only in case of late performed extractions. The biggest changes of the analyzed teeth position (the second premolars and the second permanent molars) occur in the first year after late extractions of the first permanent molars.
