Amelogenesis imperfecta (AI) represents a group of hereditary conditions which affects enamel formation in the primary and permanent dentitions. Gene mutations alter the quality and/or quantity of enamel. AI often has severe consequences for the patient such as high tooth sensitivity, low aesthetic quality of the dentition, and poor mechanical properties of the dental tissues. This can result in reduced oral health-related quality of life.
We present the case of a child affected by AI which had been diagnosed at the age of 9 years. Teeth presented many enamel defects. The patient presented thin brown to yellow enamel and the surface was rough and granular. He revealed short clinical crowns, occlusal wear with exposed dentine in posterior areas. He also presented a lateral open bite and lingual lateral interposition due to partial destruction of deciduous molars. Panoramic radiograph showed no differences between enamel and dentine appearance and also coronary destruction of permanent molars.
The initial treatment consisted of adaptation of composite resins on permanent incisors to improve aesthetics. Preformed metal crowns were placed on first permanent molars to prevent their premature destruction.
FOLLOW-UP: This was disrupted for a variety of reasons. Fourteen years later, after a dental nomadism, the patient consulted by chance a dentist who identified his genetic pathology and was aware of its consequences. Extensive prosthodontic treatment was needed, but oral hygiene was poor and gingivitis remained.
Dealing with high loss of motivation has been one of the main challenges because this patient had a lot of psychological problems. He was concerned, as are many patients affected by AI or other enamel abnormalities. This paper highlights the difficulties of long-term care of this dental abnormality. Psychological aspects of the quality of life, which is a common feature in patients suffering from many kinds of enamel anomalies, are very important.
牙釉质发育不全(AI)是一组遗传性疾病,会影响乳牙和恒牙的牙釉质形成。基因突变会改变牙釉质的质量和/或数量。AI通常会给患者带来严重后果,如牙齿高度敏感、牙列美观度低以及牙齿组织机械性能差。这可能导致口腔健康相关生活质量下降。
我们报告一例9岁时被诊断为AI的儿童病例。其牙齿存在许多牙釉质缺陷。患者的牙釉质薄,呈棕色至黄色,表面粗糙且呈颗粒状。临床牙冠短,后牙区有咬合磨损且牙本质暴露。由于乳牙磨牙部分破坏,还存在侧方开牙合和舌侧移位。全景X线片显示牙釉质和牙本质外观无差异,恒牙磨牙也有冠部破坏。
初始治疗包括在恒切牙上应用复合树脂以改善美观。在第一恒磨牙上放置预成金属冠以防止其过早破坏。
随访因各种原因中断。14年后,在辗转多地看牙后,患者偶然咨询了一位牙医,该牙医识别出了他的遗传病理并了解其后果。需要进行广泛的修复治疗,但患者口腔卫生差,牙龈炎仍然存在。
应对患者积极性严重缺失是主要挑战之一,因为该患者存在很多心理问题。他和许多受AI或其他牙釉质异常影响的患者一样感到担忧。本文强调了长期护理这种牙齿异常的困难。生活质量的心理方面,这是许多牙釉质异常患者的共同特征,非常重要。
