The impact of maxillary non-impacted third molars on the distal alveolar bone of adjacent teeth using CBCT: a retrospective study.
Objective: The purpose of the study was to determine how the maxillary non-impacted third molars impact the distal region of alveolar bone of adjacent second molars.
Method and materials: The periodontal condition of maxillary second molars for which the neighboring third molars were missing (NM3- group) and those with intact non-impacted third molars (NM3+ group) was analyzed in a retrospective study. Using CBCT, the patients were categorized based on the presence or absence of periodontitis, and the alveolar bone resorption parameters in the distal area of the second molars were measured.
Results: A total of 135 patients with 200 maxillary second molars were enrolled in this retrospective study. Compared to the NM3- group, the second molars of the NM3+ group exhibited greater odds of increasing alveolar bone resorption in the distal region (health, OR = 3.60; periodontitis, OR = 7.68), regardless of the presence or absence of periodontitis. In healthy patients, factors such as female sex (OR = 1.48) and age above 25 years old (OR = 2.22) were linked to an elevated risk of alveolar bone resorption in the distal region of the second molars. In patients with periodontitis, male sex (OR = 3.63) and age above 45 years old (OR = 3.97) served as risk factors.
Conclusions: Advanced age, sex, and the presence of non-impacted third molars are risk factors associated with alveolar bone resorption in individuals with adjacent second molars. In addition, the detrimental effects of non-impacted third molars in the population with periodontitis may be exacerbated. From a periodontal perspective, this serves as supportive evidence for the proactive removal of non-impacted third molars.
