Objectives: The current article aims to measure the prevalence of dento-maxillary anomalies within a population of children (with ages varying from 6 to 14 years old) from mining area of Rosia Montana as well as to assess the possible correlation between demographic factors (age, gender, ethnicity) and the presence of anomalies. Material and method: The study was conducted on a group of 291 children from the area with ages ranging from 7 to 14 years old (representing 33.92% of the total number of possible subjects from Rosia Montana mining area), during the phase of mixed dentition and the early stages of permanent dentition. The children were selected from schools from the mining area, both from rural and urban environments. They were examined into the medical facilities available in the area. All the personal data were collected based on the written approval of parents and will stay strictly confidential by the Romanian law and medical deontological practices. Results: About 92% of the subjects presented dento-maxillary anomalies. The results were similar if considering the gender distribution, whilst considering the age distribution of subjects the presence of anomalies varied from 84% to 100%; for ethnicity distribution of anomalies, the majority or Romanian subjects presented 94% anomalies, while Romany subjects presented 83% anomalies. Considering the 3 types of Angle malocclusions the highest percentage was for Angle Class I, respectively 61%, followed by Angle Class II/1 Angle (18%) and Angle Class II/2 (15%), while the smallest value was for Angle Class III (7%). The two categories of Angle Class II represented 33%, which was approximately half of the value for Angle Class I. Conclusion: The prevalence of dento-maxillary anomalies within the studied batch presented an average value of 92% which was significant higher than the values available within the specialized literature from Romania (values ranging from approx. 45% to 75%). This could be subject to separate in-deep studies to understand the causal.
