目的:了解广西地区7~12岁儿童牙周疾病患病状态并分析4种牙周致病菌检出情况,为减少儿童牙周疾病提供依据。方法:采用随机抽样法选取在该院进行医治的37例牙周疾病患儿,将上颌第一磨牙颊面作为被检部位,做好探诊后出血检查及探诊深度的记录,并对牙龈指数加以判断。同时,选取牙龈表面菌斑,应用PCR法检测牙龈表面4种牙周致病菌。结果:广西地区儿童患牙周疾病较为普遍,经过一系列观察分析,探诊出血阳性中牙龈卟啉单胞菌(Pg)的检出率与探诊出血阴性中Pg的检出率无统计学差异(P>0.05);而探诊出血阳性时伴放线杆菌(Aa)的检出率(70.0%)、中间普氏菌(Pi)的检出率(65.00%)、福赛坦氏菌(Tf)的检出率(70.00%)均明显高于探诊出血阴性时Aa的检出率(37.93%)、Pi的检出率(31.03%)、Tf的检出率(43.10%),差异有统计学意义(P<0.05)。7~12岁各年龄组右上第一中切牙牙周致病菌的检出率呈现不同情况。结论:广西地区7~12岁儿童患牙周疾病的概率较高,并且患儿病情发展有加重的趋势。大多数资料显示儿童牙周疾病的好发部位是儿童的磨牙区域,同时临床上对于牙周检测指标与牙周致病菌的检出存在一定的关系,从而儿童时期采取预防措施并保持牙齿清洁是非常必要的。
Objective: To understand the prevalence of periodontal disease in children aged 7 ~ 12 years in Guangxi and analyze the detection of four kinds of periodontal pathogens to provide basis for reducing periodontal disease in children. Methods: A total of 37 cases of periodontal disease undergoing treatment in our hospital were selected by random sampling. The buccal surface of the maxillary first molar was taken as the site to be examined and the hemorrhage examination and probing depth were recorded after the visit. The gums Index to be judged. At the same time, four kinds of periodontal pathogens were detected on the surface of gingival by PCR. Results: Periodontal disease was more common in children in Guangxi. After a series of observation and analysis, the detection rate of positive Pg and the detection rate of Pg in detective hemorrhage negative were not statistically significant (P> 0.05). The detection rate of Aa (70.0%), the detection rate of Prevotella intermedia (65.00%), The detection rate of Tf (70.00%) was significantly higher than the detection rate of Aa (37.93%), the detection rate of Pi (31.03%) and the detection rate of Tf (43.10% The difference was statistically significant (P <0.05). The detection rate of periodontal pathogens in the upper right first middle incisors from 7 to 12 years old showed different situations. Conclusion: The incidence of periodontal disease in children aged 7 ~ 12 years in Guangxi is high, and the progression of the disease in children is aggravating. Most data show that children with periodontal disease is the incidence of children’s molar area, while the clinical detection of periodontal indicators and detection of periodontal pathogens there is a certain relationship, so that childhood preventive measures and keep the teeth clean It is very necessary.
