Abstract

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.

使用 CBCT 测量上颌非撞击性第三磨牙对邻牙远端牙槽骨的影响：一项回顾性研究。

研究目的本研究的目的是了解上颌未受影响的第三磨牙（N-M3）对相邻第二磨牙（M2）远端牙槽骨的影响：在一项回顾性研究中分析了邻近 M3 缺失的上颌 M2（NM3 组）和 N-M3 完好的上颌 M2（NM3+ 组）的牙周状况。通过锥形束计算机断层扫描（CBCT），我们根据牙周炎的存在与否对患者进行了分类，并测量了 M2 远端区域的牙槽骨吸收参数：这项回顾性研究共纳入了 135 名上颌 200 M2s 患者。与 NM3 组相比，无论是否存在牙周炎，NM3+ 组的 M2 远端区域牙槽骨吸收增加的几率更大（健康：OR=3.60，牙周炎：OR=7.68）。在健康患者中，女性（OR=1.48）和25岁以上（OR=2.22）等因素与M2s远端区域牙槽骨吸收风险升高有关，而在牙周炎患者中，男性（OR=3.63）和45岁以上（OR=3.97）是风险因素：结论：高龄、不同性别和 N-M3s 的存在是与 M2s 患者牙槽骨吸收相关的风险因素。此外，N-M3s 对牙周炎患者的不利影响可能会加剧。从牙周的角度来看，这为主动清除 N-M3s 提供了支持性证据。
