Objective: To associate mesiodistal inclination of the second molar with the presence of premature / retrusive contact points contact in patients that would lose the first permanent molar in the UPC clinic in February 2011- March 2013 Methods: The study was observational, descriptive, cross-sectional and retrospective. The sample was formed for panoramic radiographs of 196 patients (15-60 years) who had unilateral o bilateral loss of upper or lower first molar. The characteristics of loss unilateral and bilateral upper and lower loss were evaluated to in order analyze the mesiodistal of second molars with the software ImageJ® and then it was associated with contact points, premature or retrusive. Results: The mesiodistal inclination of second molars in the maxilla was 100% of the mild type (0-29.9°) for second mandibular molars was moderate rate (30 ° - 59.9 °) by 87%. Between 40 and 60% of patients have the contact point of premature / retrusive affected by the loss of the first molar area however, no statistically significant association with the mesiodistal inclination of second molars. Conclusions: The 100% of individuals with loss of first upper molars unilateral or bilateral presented slight inclination. The 90% of individuals presented a retrusive contact point. The inclination of the second permanent molar loss of the first permanent molar, no statistically significant association with points of contact in the affected area.
