Introduction

Dryness is known to be associated with inflammatory diseases such as dry eye disease and atopic dermatitis. There is significant water loss from the oral cavity during mouth breathing. This study is conducted to estimate the influence of mouth breathing on the outcome of scaling and root planing (SRP) in chronic periodontitis (CP).

Materials and methods

CP patients comprising of 33 mouth breathers (MBs) and 33 nose breathers (NBs) were recruited. Thirty patients in each group completed the study. At baseline, plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) were measured. SRP was done in both groups. At the 4th, 8th, and 12th week, PI, GI, and BOP were recorded. PD and CAL were also assessed at the 12th week.

Results

At the 12th week, there was significantly less improvement in GI at palatal sites of maxillary anterior and maxillary posterior teeth in MB group. Sixty-nine percent of BOP positive sites with PD >4 mm were converted into BOP negative sites with PD ≤4 mm in maxillary posterior palatal sites in NB. This success was 38% in MB.

Conclusion

Control of periodontal inflammation by SRP in CP patients is affected at palatal sites of mouth breathers.

口呼吸对慢性牙周炎刮治及根面平整效果的影响

介绍

已知干燥与干眼症和特应性皮炎等炎症性疾病有关。口呼吸时口腔会大量失水。本研究旨在评估口呼吸对慢性牙周炎 (CP) 洗牙和根面平整 (SRP) 结果的影响。

材料和方法

招募了包括 33 名口呼吸者 (MB) 和 33 名鼻呼吸者 (NB) 的 CP 患者。每组 30 名患者完成了研究。在基线时，测量菌斑指数 (PI)、牙龈指数 (GI)、探诊出血 (BOP)、探诊深度 (PD) 和临床附着水平 (CAL)。两组均进行了 SRP。在第 4、8 和 12 周，记录 PI、GI 和 BOP。PD 和 CAL 也在第 12 周进行了评估。

结果

在第 12 周，MB 组上颌前牙和上颌后牙腭部的 GI 改善明显较小。NB中上颌后腭部位69%的BOP阳性部位PD>4mm转化为PD≤4mm的BOP阴性部位。这一成功率为 38%（以 MB 计）。

结论

在 CP 患者中，SRP 对牙周炎症的控制在口呼吸器的腭部位受到影响。
