This study aimed to evaluate the impact of molar incisor hypomineralization (MIH) on oral hygiene and gingival health, and to investigate the relationship between these factors and the severity of MIH.
A total of 72 children (48 with MIH and 24 healthy controls) were included in the study. MIH severity was categorized into three groups:mild (n = 16), moderate (n = 16) and severe (n = 16).The modified-Quigley Hein plaque index (m-QHPI) was used to determine oral hygiene, and the gingival index (GI) and bleeding on probe (BOP) were used to determine the gingival status of each subject. The Mann-Whitney U test was used for binary comparisons and the Kruskal-Wallis test was used for multiple comparisons.
The m-QHPI,GI and BOP were significantly higher in all individuals with MIH compared with the control group. The m-QHPI increased with the severity of MIH (P < 0.001).The GI of the MIH-affected teeth had highly significant increases according to MIH severity (P < 0.05). The mean BOP score for the entire mouth was significantly higher in patients with severe and moderate MIH than mild MIH (P < 0.001). The mean BOP for affected teeth with moderate and severe MIH was significantly higher than the mean BOP of mildly affected teeth (P < 0.05).

本研究旨在评估磨牙牙釉质发育不全（MIH）对口腔卫生和牙龈健康的影响，并探讨这些因素与 MIH 严重程度之间的关系。
本研究共纳入 72 名儿童（MIH 组 48 名，健康对照组 24 名）。MIH 严重程度分为三组：轻度（n=16）、中度（n=16）和重度（n=16）。采用改良 Quigley-Hein 菌斑指数（m-QHPI）评估口腔卫生状况，采用牙龈指数（GI）和探诊出血（BOP）评估每位受试者的牙龈状况。采用 Mann-Whitney U 检验进行二项比较，采用 Kruskal-Wallis 检验进行多项比较。
所有 MIH 患者的 m-QHPI、GI 和 BOP 均显著高于对照组。m-QHPI 随 MIH 严重程度增加而升高（P<0.001）。MIH 受累牙的 GI 随 MIH 严重程度显著增加（P<0.05）。重度和中度 MIH 患者的全口平均 BOP 评分显著高于轻度 MIH（P<0.001）。中度和重度 MIH 受累牙的平均 BOP 显著高于轻度受累牙（P<0.05）。
MIH 的存在和严重程度可能与菌斑堆积和牙龈炎症增加有关。© 2022 澳大利亚牙科协会。
