    Objective: To analyze the association between the impaction of lower third molars and the available space for eruption in patients treated at a dental center in Lima, 2021. Material and Methods: A basic, correlational, and cross-sectional study was conducted. A total of 165 panoramic radiographs were used, and a Chi-square statistical test was performed. Results: Regarding the available space, it was observed that 56.4% of the cases had a 70% probability of eruption, and 43.6% had a 30% probability of eruption. For the impaction of lower third molars according to the ascending ramus and available space, the most frequent was Class II at 75.3%, with a 70% probability of eruption, 14.0% for Class I with a 70% probability of eruption, and 25.0% for Class III with a 30% probability of eruption. Regarding the position of the mandibular third molars and available space, the frequency observed for the mesioangular position was 75.3% with a 70% probability of eruption, for the vertical position 19.4% with a 70% probability of eruption, and for the horizontal position 19.4% with a 30% probability of eruption. Finally, regarding relative depth and available space, the most frequent level was Level B at 72.0% with a 70% probability of eruption, followed by Level A at 25.8% with a 70% probability of eruption, and Level C at 5.6% with a 30% probability of eruption. Conclusions: The study variables establish a significant relationship between the impaction of lower third molars and available space.

    Relationship between the space of the lower third molar and the different skeletal patterns in patients aged 12 to 17 years who attend the dental center“ scientific dental, Lima 2017-2019.

    The purpose of this research was to determine the relationship between the space for the lower third molar and different skeletal patterns in patients aged 12 to 17 years who attended the Dental Científica center, Lima, 2017-2019. The study was observational, descriptive, cross-sectional, and retrospective. The study population consisted of 178 cephalometric and 178 panoramic radiographs, analyzed using the observation technique. Skeletal classes were determined by measuring the ANB angle (Steiner), and the space for the lower third molar was measured in millimeters using the Nemoceph version 2.0 software in Spanish. Results: No significant relationship was found between the space for the lower third molar and skeletal classes (p=0.94). The most frequent skeletal class was class II (47.2%), followed by class I (44.4%). Regarding the space for the lower third molar (ERTM), the general average was 8.72±4.22 mm for the right side and 9.86±4.26 mm for the left side. The ERTM values by age showed higher averages in 17-year-old patients, with 9.91±3.74 mm for the right side and 11.79±3.84 mm for the left side. Conclusion: There is no significant relationship between the space for the lower third molar and skeletal patterns.
