To reveal need for prosthodontics in permanent teeth in children aged 8-18 years.
The study was performed in Khimki Dental Municipal Clinic. Dental examination and radiological studies were conducted in 97 primary patients aged 8-18 years. Indications for prosthodontics in permanent teeth were occlusal deterioration index more than 40% and crown decay of more than 50% in incisors and canines. Additional features were registered including DMFT index, the presence of extracted teeth and teeth after root canal treatment, as well and teeth with extensive restorations with resins and marginal seal quality.
From 97 primary patients (27.8%) children needed prosthodontics in permanent teeth (in average 2.3±2.1 teeth): 1 tooth in 10 children, 2 teeth in 11 children, 3 teeth in 1 child, 4 teeth in 3 children and 4 teeth in 2 children. Mean DMFT was 8.1±4.5 teeth. Six children already had extracted permanent teeth (9 teeth in total). Half of the teeth (49.2%) which needed orthodontic treatment had history of root canal treatment while 46% needed primary or secondary endodontic treatment. Occlusal deterioration index was more than 40% in 41.3% of cases, more than 60% in 49.2% of teeth and more than 80% in 9.52% of teeth. From all the teeth restored with composite resins 41.7% had good marginal seal but 58.3% showed macroscopic signs of marginal leakage.
Our study shows high percentage of adolescents having need for prosthodontics in permanent teeth and unjustified widening of indications for direct resin restorations in this group of patients.
揭示8至18岁儿童恒牙修复的需求。
该研究在希姆基市立牙科诊所进行。对97名8至18岁的初级患者进行了牙科检查和放射学研究。恒牙修复的指征为咬合恶化指数超过40%,以及切牙和尖牙的冠部龋坏超过50%。还记录了其他特征,包括龋失补指数、拔牙情况、根管治疗后的牙齿情况,以及树脂广泛修复的牙齿和边缘封闭质量。
在97名初级患者中,27.8%的儿童需要恒牙修复(平均2.3±2.1颗牙齿):10名儿童有1颗牙齿需要修复,11名儿童有2颗牙齿需要修复,1名儿童有3颗牙齿需要修复,3名儿童有4颗牙齿需要修复,2名儿童有4颗牙齿需要修复。平均龋失补指数为8.1±4.5颗牙齿。6名儿童已经拔除了恒牙(共9颗)。需要正畸治疗的牙齿中有一半(49.2%)有根管治疗史,而46%需要进行初次或二次牙髓治疗。41.3%的病例咬合恶化指数超过40%,49.2%的牙齿超过60%,9.52%的牙齿超过80%。在所有用复合树脂修复的牙齿中,41.7%的边缘封闭良好,但58.3%有边缘渗漏的宏观迹象。
我们的研究表明,青少年恒牙修复的需求比例很高,并且在这组患者中直接树脂修复的指征存在不合理扩大的情况。
