儿童乳磨牙龋源性根尖周病的发病特点及治疗效果分析

Analysis on the Characteristics and Therapeutic Effect of Periapical Disease Induced by Deciduous Molar Tooth Caries in Children

目的研究我院儿童乳磨牙龋源性根尖周病的发病特点,并分析治疗效果。方法选取2015年2月至2016年12月我院收治的乳磨牙龋源性根尖周病儿童500例,共有患牙772颗。按照龋损累及牙面的不同分成面组212颗以及邻面组560颗。分别对两组儿童的性别、年龄、好发牙位以及患牙类型进行统计。同时进行乳牙根管治疗,分析治疗效果。结果 (1)500例儿童中男276例,女224例;年龄<5岁人数为160例,5~7岁人数为258例,>7岁人数为82例。(2)面组年龄<5岁儿童患牙占比为71.70%(152/212),显著高于5~7岁以及>7岁儿童的16.04%(34/212)、12.26%(26/212),差异均有统计学意义(P<0.05);下颌乳磨牙患牙占比为72.64%(154/212),显著高于上颌乳磨牙的27.36%(58/212),差异有统计学意义(P<0.05);第二乳磨牙患牙占比为64.62%(137/212),显著高于第一乳磨牙的35.38%(75/212),差异有统计学意义(P<0.05)。(3)邻面组年龄5~7岁儿童患牙占比为54.46%(305/560),显著高于<5岁以及>7岁儿童的25.36%(142/560)、20.18%(113/560),差异均有统计学意义(P<0.05);第一乳磨牙患牙占比为72.32%(405/560),显著高于第二乳磨牙的27.68%(155/560),差异有统计学意义(P<0.05)。(4)经根管治疗后,500例儿童患牙治疗成功率为90.03%(695/772)。结论儿童乳磨牙龋源性根尖周病具有发病低龄化特点,应积极进行根管治疗,并对患儿及其家长加强口腔卫生宣教,定期复查,可降低发病率。

Objective To study the characteristics ofperiapical disease induced by deciduous molar tooth caries in children, and to analyze the therapeutic effect. Methods 500 cases of children with periapical disease induced by deciduous molar tooth caries admitted to our hospital from February 2015 to December 2016 were selected, including 772 affected teeth. According to the different locations of caries, all cases were divided into the occlusal caries group （n = 212） and the interproximal caries group （n = 560）. The gender, age, predilection site, and affected teeth type of two groups were statistically analyzed. All cases were given root canal therapy of deciduous teeth, and the therapeutic effect was analyzed. Results （1）Among 500 children, there were 276 cases of male and 224 cases of female, 160 cases younger than 5 years old, 258 cases aged from 5 - 7 and 82 cases older than 7 years old. （2）Among 212 affected teeth of occlusal caries group, the proportion of affected teeth of children younger than 5 was 71.70% （152/212）, significantly higher than 16.04% （34/212） of children ages from 5 - 7 and 12.26% （26/212） of children older than 7, with statistical differences （P 〈0.05）; The proportion of affected mandibular deciduous molar was 72.64% （154/212）, significantly higher than 27.36% （58/212） of affected maxillary deciduous molar, with statistical difference （P〈0.05）; The proportion of affected second deciduous molar was 64.62% （137/212）, significantly higher than 35.38% （75/212） of affected first deciduous molar, with statistical difference （P 〈0.05）. （3） Among 560 affected teeth in interproximal caries group, the proportion of affected teeth of children ages from 5 - 7 was 54.46% （305/560）, significantly higher than 25.36% （142/560） of children younger than 5 and 20.18% （113/560） of children older than 7, with statistical differences （P 〈0.05）; The proportion of affected first deciduous molar was 72.32% （405/560）, significantly higher than 27.68% （155/560） of affected second deciduous molar, with statistical difference （P〈0.05）. （4）The success rate of root canal therapy of 500 children （772 affected teeth） were 90.03% （695/772）. Conclusions The periapical disease induced by deciduous molar tooth caries in children shows characteristics of younger onset, and root canal therapy should be performed in clinic. It is necessary to strengthen the education of oral health to children and their relatives and review regularly, so as to reduce the morbidity.
