The present study was conducted to assess the effects of mouth breathing, lip seal and upper lip coverage on gingival health of children. 240 school children aged 10-14 years were selected irrespective of sex race and socioeconomic status. They were divided into two major groups i.e. mouth breathers and normal breathers. These groups were further subdivided into six sub-groups or categories on the basis of lip seal and upper incisor coverage. Gingival index was found to be higher in the mouth breathers than in the normal breathers in the subjects with incompetent lip seal. Increased lip separation and decreased upper lip coverage were all associated with higher levels of Plaque index and Gingival index. No statistical difference existed between mouth breathers and normal breathers with respect to Plaque index.
本研究旨在评估口呼吸、唇闭合及上唇覆盖对儿童牙龈健康的影响。选取了240名年龄在10至14岁之间的学童，不考虑其性别、种族和社会经济地位。他们被分为两大组，即口呼吸者和正常呼吸者。这些组再根据唇闭合和上切牙覆盖情况进一步细分为六个亚组或类别。发现在唇闭合不全的受试者中，口呼吸者的牙龈指数高于正常呼吸者。唇间距增加和上唇覆盖减少均与更高水平的菌斑指数和牙龈指数相关。在菌斑指数方面，口呼吸者和正常呼吸者之间不存在统计学差异。
