To compare the gingival health and periodontal status in primary molars restored with stainless steel crowns with unrestored contralateral teeth.
A split mouth design study was conducted on 60 children aged 5- 10 years who required stainless steel crown restoration on deciduous molars. The molar teeth restored with stainless steel crown were selected for study and healthy unrestored contralateral teeth were selected as controls. Bitewing radiograph of study and control tooth was taken at initial, three months and at six months. The gingival status, oral hygiene status was evaluated at three months and six month intervals using gingival index and oral hygiene index respectively.
On evaluating the oral hygiene status at three months study group showed the mean value of 0.7±0.700 whereas in control group it was 1±0.368. At six months it was 1.183±0.390 in study group and 1.5±0.504 in control group. Chi square test shows that the crown marginal adaptation produced statistically significant difference at six months. Crown marginal extension did not produce any difference on gingival index and oral hygiene index.
When compared to control teeth, the teeth restored with stainless steel crown showed lesser plaque and debris accumulation at three months and six months. Radiographic bone level the control teeth showed higher level of bone resorption compared to the teeth restored with stainless steel crown.
比较用不锈钢冠修复的乳磨牙与对侧未修复牙齿的牙龈健康状况和牙周状态。
对60名年龄在5至10岁、需要对乳磨牙进行不锈钢冠修复的儿童进行了一项半口设计研究。选择用不锈钢冠修复的磨牙进行研究,并选择健康的对侧未修复牙齿作为对照。在初始、三个月和六个月时拍摄研究牙和对照牙的咬合翼片。分别在三个月和六个月的间隔时间使用牙龈指数和口腔卫生指数评估牙龈状况和口腔卫生状况。
在三个月时评估口腔卫生状况,研究组的平均值为0.7±0.700,而对照组为1±0.368。在六个月时,研究组为1.183±0.390,对照组为1.5±0.504。卡方检验表明,冠边缘适应性在六个月时产生了统计学上的显著差异。冠边缘延伸在牙龈指数和口腔卫生指数上没有产生任何差异。
与对照牙相比,用不锈钢冠修复的牙齿在三个月和六个月时显示出较少的菌斑和牙垢堆积。影像学上,对照牙的骨吸收水平高于用不锈钢冠修复的牙齿。
