本研究探讨MTA和Biodentine对临床和影像学成功率的牙髓切断术进行乳牙龋牙髓exposition.Materials和methodsThis研究进行了44下颌乳磨牙需要活髓切断术的影响。以暴露部位周围的龋坏牙本质为入选标准，根据活髓切断术材料的不同随机分为2组[MTA组（n=24），Biodentine组（n=20）]。随访24个月。髓管闭塞不被视为failure.Results24个月结束时的临床和影像学成功率为100%的MTA组和89.4%的Biodentine组。两组的成功率无显著差异（p=0.646）。2颗牙发生髓管闭塞6个月时MTA组为8.3%，但在24个月时发现牙齿稳定。本研究中获得长期临床和放射学成功率表明，MTA和Biodentine都是适合于那些需要长期保留牙齿的患者的乳牙龋坏暴露的活髓切断治疗的选择。暴露的病因决定了牙髓的反应，因此区分机械性暴露和龋性暴露至关重要。据推测，龋齿暴露伴随着严重的炎症，这使得治疗的预后不可预测。生物材料可用于特别是在案件与龋牙髓暴露。
ObjectiveThis study examined the effects of MTA and Biodentine on the clinical and radiographic success rates of pulpotomies performed on primary teeth with carious pulp exposures.Materials and methodsThis study was conducted with 44 mandibular primary molars requiring vital pulpotomy. Carious dentin surrounding the exposure site was used as the inclusion criteria for all teeth, which were randomly divided into two groups according to pulpotomy material [MTA group (n=24), Biodentine group (n=20)]. Treatment was followed up clinically and radiologically for 24months. Pulp canal obliteration was not regarded as a failure.ResultsClinical and radiographic success rates at the end of 24months were 100% for the MTA group and 89.4% for the Biodentine group. Success rates did not vary significantly between the groups (p=0.646). Pulp canal obliteration was observed in two teeth (8.3%) in the MTA group at 6months, but the teeth were found to be stabilized by 24months.ConclusionThe long-term clinical and radiographic success rates obtained in this study indicate that both MTA and Biodentine are appropriate options for pulpotomy treatment of primary teeth with carious exposure in patients whose teeth should be retained for long periods of time.Clinical relevanceThe etiology of exposure determines pulpal response, making it crucial to distinguish between mechanical and carious exposures. The carious exposure is presumed to be accompanied by severe inflammation, which makes the prognosis of treatment unpredictable. Biomaterials can be used especially in cases with carious pulp exposures.
