To determine the prevalence of oral habits in the mixed dentition of schoolchildren in Dharan, Nepal and compare this prevalence between sexes, races, and age.
A cross-sectional study was conducted among 830 schoolchildren of 10 randomly selected schools in Dharan. The presence or absence of oral habits was determined using a structured questionnaire, and an oral examination of the children was carried out under natural light. A chi-square test was used to compare the association of oral habits with age, sex and race.
The most prevalent oral habit was tongue thrusting (39.6 percent), while the habit of biting objects was the least prevalent (0.8 percent). Mouth-breathing was statistically significant for sex ( = 0.010), whereas biting objects ( = 0.035) and self-inflicting habits ( = 0.005) were statistically significant for race. Lip sucking ( ≤0.001) and lip-biting habits ( = 0.001) were statistically significant for age.
These findings highlight the importance of periodic screenings and timely referral for the early detection of oral habits and its associated effect on the developing occlusion.
为确定尼泊尔达兰地区学龄儿童混合牙列期口腔习惯的患病率，并比较不同性别、种族和年龄之间的患病率。
在达兰地区随机选取的10所学校的830名学龄儿童中开展了一项横断面研究。通过结构化问卷确定是否存在口腔习惯，并在自然光线下对儿童进行口腔检查。采用卡方检验比较口腔习惯与年龄、性别和种族之间的关联。
最常见的口腔习惯是吐舌（39.6%），而咬物习惯最为少见（0.8%）。口呼吸在性别方面具有统计学意义（P = 0.010），而咬物习惯（P = 0.035）和自我伤害习惯（P = 0.005）在种族方面具有统计学意义。吮唇习惯（P≤0.001）和咬唇习惯（P = 0.001）在年龄方面具有统计学意义。
这些研究结果凸显了定期筛查以及及时转诊以早期发现口腔习惯及其对正在发育的咬合的相关影响的重要性。
