摘要
目的:探究分析不同防龋方法在学龄前儿童中的应用及对口腔链球菌的影响。方法:选取2017年1月-2019年1月在本院口腔科就诊的82例学龄前儿童,依据不同防龋方法将其分为空白组(n=22)、氟化泡沫组(n=30)及氟保护漆组(n=30)。空白组仅进行龋齿的防治等口腔卫生宣教,氟化泡沫组行氟化泡沫防龋干预,氟保护漆组接受氟保护漆干预。对比三组防龋前后患龋、唾液中链球菌菌群数量变化,评价三组防龋后牙釉质脱矿情况。结果:防龋18个月后,氟保护漆组患龋例数、龋洞数量均低于空白组和氟化泡沫组,氟化泡沫组龋洞数量低于空白组,差异均有统计学意义(P<0.05)。防龋18个月后,氟保护漆组口腔链球菌、唾液链球菌、血链球菌及变异链球菌数量均低于其他两组,差异均有统计学意义(P<0.05)。防龋18个月后,氟保护漆组牙釉质脱矿程度与脱矿指数均优于空白组、氟化泡沫组,差异均有统计学意义(P<0.05)。结论:氟化泡沫与氟保护漆均能有效预防学龄前儿童龋病,但氟保护漆的效果更突出,对口腔链球菌的影响更为显著。
Objective:To explore and analyze the application of different anti-caries methods in preschool children and its influence on streptococcus oralis.Method:A total of 82 preschool children who treated in the stomatology department of the hospital from January 2017 and January 2019 were selected,according to different anti-caries methods,they were divided into three groups,the blank group(n=22),the fluorinated foam group(n=30)and the fluorinated paint group(n=30).The blank group only received dental caries prevention and treatment oral hygiene education,the fluorinated foam group received fluoride foam caries prevention intervention,the fluorinated paint group received fluoride protective paint intervention.The numbers of caries and Streptococcus in saliva of three groups before and after caries prevention were compared,the enamel demeralization of three groups was evaluated.Result:At 18 months after caries prevention,the number of caries cases and cavities in the fluorinated paint group were lower than those in the blank group and the fluorinated foam group,the number of cavities in the fluorinated foam group was lower than that in blank group,the differences were statistically significant(P<0.05).At 18 months after caries prevention,the number of oral streptococcus,streptococcus salivary,streptococcus sera and streptococcus mutans in the fluorinated paint group were lower than those in the other two groups,the differences were statistical significance(P<0.05).At 18 months after caries prevention,the enamel demineralization degree and demineralization index in the fluorinated paint group were better than those in the blank group and the fluorinated foam group,the differences were statistical significance(P<0.05).Conclusion:Both fluorinated foam and fluorinated paint can effectively prevent preschool children from caries,but the effect of caries is more prominent,its effect on Streptococcus oralis is more significant.
