Abstract
Amelogenesis imperfecta is a group of conditions caused by over 15 different genes that affects the development of dental enamel and poses some challenges to dentists. An adult patient with amelogenesis imperfecta with severe changes in tooth color and reduction of occlusal vertical dimension sought dental treatment. Diagnostic wax-up was carried out to guide the stratification of a nanoparticulate resin for the restorative treatment. Direct composite resin restorations were applied on all teeth for modification of both esthetics and occlusion. After a 2-year follow-up, the findings appear to suggest that composite resin is a low-cost alternative when compared with indirect ceramic restorations, provides a good esthetic outcome, and offers considerable longevity for cases like the one reported herein.
Highlights
Amelogenesis imperfecta (AI) is a group of conditions caused by over 15 different genes that affects dentition, with variable prevalence rates depending on the population assessed
AI patients have difficulty maintaining oral hygiene, impaired chewing ability, and lower self-esteem, which eventually affect their overall quality of life [1, 2]
AI can be categorized into type I that involves disturbances related to enamel secretion, type II that is related to enamel maturation, type III that affects the mineralization process, and type IV, which is marked by the involvement of hypoplastic and hypomature enamel defects associated with taurodontism
Summary
Amelogenesis imperfecta (AI) is a group of conditions caused by over 15 different genes that affects dentition, with variable prevalence rates depending on the population assessed. Direct composite resin restorations can disguise tooth discoloration and improve dental esthetics, in addition to requiring less preparation or no preparation at all for preserving the tooth structure. This is a good option for AI patients [3]. Nanoparticulate resins allow adequate polishing and are resistant enough to maintain the esthetics and function of the guides used for disclusion and of restorations in case of extensive rehabilitations [4] They are less time-consuming and less costly, since they do not require any sessions for molding and testing, unlike indirect restorations. The aim of the present study is to report a clinical case of an AI patient treated with direct composite resin and followed up for 2 years
