ABSTRACTMalocclusion is a common problem in the population and one that contributes to the development of diseases such as caries and periodontal disease, generating high social and economic costs and severe effects on self-esteem. Therefore, it is important to identify the intrinsic factors that cause it in order for it to be eliminated or corrected. General objective: To determine the prevalence of malocclusion and identify the intrinsic factors in its etiology in a population of both sexes with permanent dentition. Materials and methods: 134 patients of both sexes from an accredited dental school in the state of Guanajuato were examined in search of risk factors intrinsic to malocclusion; none of the patients had any history of extractions or prior dental treatment. Results: 98.51% of patients had one or other risk factor. 253 intrinsic factors were found, the most common being impacted teeth (28.36%) and retained teeth (21.64%). In terms of groups of factors, tooth eruption problems and dentoalveolar discrepancies were the most common. Conclusions: Intrinsic factors in malocclusion are very common in the general population. They can be identified during dental examination to allow early corrective treatment or their elimination to prevent oral health problems.
