摘要
目的:评价上颌前磨牙根面凹陷对老年牙周炎患者局部牙槽骨吸收的影响。方法:纳入61～82岁的慢性牙周炎患者19例共62个同侧上颌第一、二前磨牙(n=31),其中第一前磨牙存在根面凹陷(A组),第二前磨牙无根面凹陷(B组)。CBCT测量牙槽骨吸收类型及程度,比较根面凹陷对局部牙槽骨吸收的影响。结果:A组和B组牙槽骨斜型吸收分别有36个位点和21个位点; A组和B组近中位点牙槽骨吸收水平(mm)分别为3. 85±1. 31和3. 37±0. 86(P <0. 05)。结论:上颌第一前磨牙根面凹陷会促进老年牙周炎患者局部牙槽骨吸收。
Objective: To study the effects of root grooves on alveolar bone resorption of maxillary premolar in elderly patients with periodontitis. Methods: 31 pairs of the first premolar with root groove( group A) and second premolar without root groove( group B) of the same side from 19 elderly patients with chronic periodontitis were included. The pattern and degree of alveolar bone resorption were measured by CBCT at 6 sites of each tooth. The relation of root groove with the bone resorption patterns and degree was analyzed. Results: The oblique alveolar bone resorption of group A and B was observed at 36 sites and 31 sites respectively( P < 0. 05),at M site the alveolar bone resorption( mm) of group A and B was 3. 85 ± 1. 31 and 3. 37 ± 0. 86( P < 0. 05). Conclusions: Root groove of maxillary first premolar can promote local alveolar bone resorption in elderly patients with periodontitis.
