Objective The aim of this study was to describe the occurrence, angulation and mesialisation ratio ectopic eruption maxillary permanent first molar (PFM) its correlation with pathological resorption primary second (PSM). Methods This retrospective performed using subsequent panoramic radiographs 11.924 child patients aged 6-10 years. Ectopic status is categorised as self-corrected impacted types. To evaluate differences between two groups (self-corrected impacted), PFM, degree adjacent PSM root were also assessed. data statistically analysed ANOVA chi-square tests. Pearson used analyse whether a quantitative relationship exists PFM resorption. Results frequency determined 0.83%. distribution according gender shows higher prevalence in males than females. In most cases eruption, impacted. PFMs showed more negative vertical positive horizontal angle PFM. There no significant difference angles. Mesialisation significantly PFMs. Conclusion Even if disturbances do not occur frequently, making an early diagnosis important begin treatment at optimal time. Although angles pattern controversial, it one clinical determinants. type type. Self-correction reduced grade III IV
