Abstract
Pre-eruptive enamel lesions occur during tooth formation and include fluorosis, traumatic hypomineralization, and molar incisor hypomineralization. Minimally invasive treatment approaches, such as microabrasion, should be considered for these cases. This article presents a case series of three patients with pre-eruptive enamel defects in esthetically compromised tooth regions which were treated with the microabrasion technique: two fluorosis cases, moderate and advanced, and one hypomineralization case of traumatic etiology. In Cases 1 and 3, there was a significant improvement in esthetics with a total resolution of the enamel defects. However, a slight yellowish coloration may be detected at close observation. In Case 2 (advanced fluorosis), although there was no full resolution of the white spots, there was a clear improvement in esthetics. Microabrasion is a safe and effective, minimally invasive treatment for pre-eruptive enamel lesions. It does not require local anesthesia, it is less destructive than restorative interventions, and allows good esthetic outcomes with no significant postoperative sensitivity. Its efficacy is directly related to the lesions’ severity and depth. Although there are some limitations, further improvement can be achieved with dental bleaching. More invasive treatments might be considered if results are still unsatisfactory.
Highlights
Smile esthetics is a constant concern for patients, especially for the young generations
The same applies to Case 3 (Figure 4), in which the white enamel defect on tooth 11 was solved but an underlying yellowish coloration was revealed
Even though there was no total resolution of the white spots, there was a clear improvement in esthetics as the microabrasion procedure was able to provide more uniformity, smoothness, and luster to the enamel
Summary
Smile esthetics is a constant concern for patients, especially for the young generations. White enamel lesions are an example of a clinical condition corresponding to an enamel hypomineralization, which translates into a porous enamel surface that can, depending on the severity of each particular case, affect patients’ lives and wellbeing [1,2,3]. These white defects can be classified as pre- or post-eruptive lesions [1]. They develop in sites prone to plaque accumulation such as the labial cervical third or around orthodontic appliances
