Opis: Objectives:This study was done to determine the timing of eruption of permanentteeth by sex and the number of permanent teeth erupted at different ages and toassess its association with malocclusion. Material and Methods:The sample for this study consisted of 633 healthy subjects(317 boys and 316 girls) aged between 5.0 and 15.0 years. The subjects were dividedinto subgroups considering an age interval of 1 year. Results:The mean eruption times were lower for girls compared with boys exceptfor the maxillary and mandibular second premolars and second molars, which werefound to erupt earlier in boys. All the permanent mandibular teeth, except thesecond premolars, tended to erupt earlier than their maxillary antagonists in bothsexes. The sequence of eruption differs between girls and boys in the maxillarycanine and maxillary second premolars. In Class III malocclusion, all the permanentmandibular teeth erupt earlier than their maxillary antagonists. In the entire sample,the correlation between the number of erupted teeth and age was strong (p< .05),but the differences between sexes were not significant. Conclusions:It is important to know the normal eruption time of permanent teeth inthe population due to diagnosis and better treatment planning in pediatric dentistryand orthodontics.
