妊娠期龈炎与口腔卫生的相关性研究

目的:探讨妊娠期龈炎与口腔卫生的关系,为预防妊娠期龈炎提供依据。方法:选择204例身体健康有妊娠期龈炎的孕妇为龈炎组,61例无龈炎孕妇作为对照组,进行问卷调查和口腔检查。记录文化程度、每日刷牙次数、咀嚼口香糖习惯、龈炎指数及妊娠前龈出血状况。结果:妊娠期龈炎组的牙石及妊娠前龈出血的发生率分别为88%和61%,显著高于对照组25%和18%;龈炎组仅有8%有咀嚼口香糖习惯,明显低于对照组的48%。妊娠期龈炎组中每日刷牙2次组的龈炎指数(1.12±0.53)明显高于每日刷牙3次组(0.47±0.36)。结论:妊娠期龈炎的发生与孕妇每日刷牙次数、咀嚼口香糖等口腔卫生措施及妊娠前龈炎状况有关,提示加强口腔卫生并在妊娠前治疗龈炎是减少妊娠期龈炎的有效途径。

Study on Relationship Between Pregnancy Gingivitis and Oral Health Care

Objective:To investigate the relationship between pregnancy gingivitis and oral health care in pregnant women and to provide clinical evidences for preventing pregnancy gingivitis.Methods:204 pregnancy gingivitis patients and 61 gingival healthy pregnant woman controls with body health were included.Their education and brush one's teeth condition,chewing gum custom and gingival index(GI) were examined;gingival bleeding condition before pregnancy was estimated.Results:The dental calculus formation rat and the gingival bleeding rat before pregnancy were 88% and 61% in pregnancy gingivitis group,which were significantly more than 25% and 28% in contrast group.In chewing gum custom,pregnancy gingivitis patients showed 8% compared with 48% in contrast group(P<0.05).GI in two times brush one's teeth of pregnancy gingivitis group was 1.12±0.53,and that in three times brush one's teeth was 0.47±0.36,the difference of GI was significant for two groups.Conclusion:In present study,pregnancy gingivitis formation were significantly correlated with brush one's teeth condition,chewing gum custom,and gingival state before pregnancy.That indicates to heighten oral health may have preventive effects on pregnancy gingivitis formation.
