Abstract

Introduction. Glass-ionomer cements and composite materials are widely used for direct restoration of carious lesions, also in young permanent teeth. However, knowledge on the effects of cariogenic factors on the quality of restorations performed using these materials, especially those covering proximal surfaces, which are more often exposed to bacterial plaque, is insufficient. Aim. The aim of the study was to assess the impact of oral hygiene and increased intensity of caries on proximal composite and glass ionomer restorations in young permanent teeth after 2 years of usage. Material and methods. Equia Fil glass-ionomer and Tetric EvoCeram composite restorations were performed in patients aged between 12 and 20 years with proximal carious lesions in premolars and molars. The clinical condition of restorations was assessed and indices such as OHI-S and D1-2DMFT (along with their increased values) were calculated at baseline, as well as during follow-up visits at 6, 12, 18 and 24 months. Correlations between clinical assessment of restorations and indices for oral hygiene and caries intensity, their increase and increased number of teeth with carious spots were evaluated. The study was approved by the Bioethics Committee of the Medical University of Warsaw (No. KB/157/2013). Results. A total of 100 proximal restorations were performed in 49 patients. After 24 months, 98 restorations (50 Equia Fil and 48 Tetric EvoCeram) were evaluated. Mean baseline OHI-S and D1-2DMFT were 1.37 and 12.04, respectively, for Equia Fil restorations, and 1.27 and 10.38 for Tetric restorations, with the following values reported during follow-up: 1.80 and 15.4; 1.63 and 12.38. Statistically significant relationships were found between OHI-S and values describing the state of materials. These values increased with increasing OHI-S and D1-2DMFT. Conclusions. Both Tetric Evo Ceram and Equia Fil restorations are susceptible to cariogenic factors.
口腔卫生、龋病强度及增加对恒牙近端复合修复体的影响
介绍。玻璃离子聚合物和复合材料被广泛用于直接修复龋齿损伤,也用于年轻的恒牙。然而,关于龋齿因素对使用这些材料进行修复质量的影响的知识,特别是那些覆盖近端表面的材料,更经常暴露于细菌菌斑,是不够的。的目标。本研究的目的是评估口腔卫生和龋齿强度增加对使用2年后的年轻恒牙近端复合修复体和玻璃离子修复体的影响。材料和方法。Equia Fil玻璃离子和Tetric EvoCeram复合修复体用于12 - 20岁的前磨牙和磨牙近端龋齿病变患者。评估修复体的临床状况,并在基线以及6、12、18和24个月的随访期间计算OHI-S和D1-2DMFT等指标(及其增加值)。评价修复体临床评价与口腔卫生指标、龋病强度、龋病加重数及龋斑增加数的相关性。该研究得到了华沙医科大学生物伦理委员会的批准。KB / 157/2013)。结果。49例患者共进行近端修复100次。24个月后,对98个修复体(50个Equia Fil和48个Tetric EvoCeram)进行评估。Equia Fil修复体的平均基线ohi和D1-2DMFT分别为1.37和12.04,Tetric修复体的平均基线ohi和D1-2DMFT分别为1.27和10.38,随访期间报告的值如下:1.80和15.4;1.63和12.38。统计上发现ohi与描述材料状态的值之间存在显著关系。这些值随着ohi和D1-2DMFT的增加而增加。结论。Tetric Evo Ceram和Equia Fil修复体都容易受到龋齿因素的影响。
