The objective of this investigation was to evaluate the clinical performance of composite restorations in enamel hypomineralised posterior teeth.
52 composite restorations were placed in 52 permanent molars of 46 children, aged 8-10 years. All the teeth were clinically diagnosed as hypomineralised and restorations were placed on two or more surfaces of the teeth, including cusps. All treated teeth had at least 2 sound surfaces, thus excluding defective teeth with total disruption of the crown. The materials used were a hybrid composite and a fourth generation one-bottle adhesive material and manufacturer's instructions were carefully followed. The restorations were initially evaluated 7 days after the treatment and subsequent evaluation was performed at 12, 24, 36, 48 months. Clinical evaluation of the restorations was made according to the criteria of Ryge [1980].
In 6 cases, postoperative complaint was relieved after occlusal re-adjustment at the second appointment, 7 days later. At the end of the 48 months study period, 49 restorations were available for evaluation, all with full retention. Radiographically there was no periapical pathology. Problems were found in colour match in 10, surface appearance in 3 and anatomic form in 4 restorations. Hypersensitivity was recorded in 17 teeth after one week and in 3 teeth one year later. All teeth were sensitivity free after two years and until the end of the study period.
Composite resin restorations using contemporary materials, in certain cases of hypomineralised permanent molars, can be an acceptable restorative procedure with satisfactory long-term results.
本研究的目的是评估复合树脂修复体在釉质矿化不全后牙中的临床性能。
在46名8至10岁儿童的52颗恒磨牙中放置了52个复合树脂修复体。所有牙齿经临床诊断为矿化不全，修复体置于牙齿的两个或更多表面，包括牙尖。所有治疗的牙齿至少有2个健康表面，因此排除了冠部完全破坏的有缺陷牙齿。使用的材料是一种混合复合树脂和一种第四代单瓶粘结材料，并严格遵循制造商的说明。修复体在治疗后7天进行初始评估，随后在12、24、36、48个月进行评估。根据Ryge[1980]的标准对修复体进行临床评估。
6例患者在7天后的第二次就诊时经咬合重新调整后术后不适得到缓解。在48个月的研究期结束时，有49个修复体可供评估，所有修复体均完全保留。影像学检查未见根尖周病变。10个修复体存在颜色匹配问题，3个修复体存在表面外观问题，4个修复体存在解剖形态问题。17颗牙齿在1周后出现过敏反应，1年后有3颗牙齿出现过敏反应。所有牙齿在2年后直至研究期结束时均无过敏反应。
在某些釉质矿化不全的恒磨牙病例中，使用当代材料的复合树脂修复可以是一种可接受的修复方法，具有令人满意的长期效果。
