Micro-Invasive Treatment with Resin Infiltration Technique- an Option?

Description of clinical cases: Two clinical cases will be presented. Female patient, 21 years old, unhappy with the presence of unaesthetic spots on teeth of the anterior-superior sector (1.3-2.3) associated with demineralization lesions after removing the orthodontic appliances. Resin infiltration technique was performed. Male patient, 36 years old, dissatisfied with the appearance of his maxillary central incisors. We started by evaluating the extent and depth of white spot lesions by transilumination with light curing. The physical and clinical history evaluation led to the diagnosis of hypomineralization on teeth 2.1 and 1.1. Microabrasion enamel technique followed by resin infiltration technique were performed. Discussion: This method uses a low viscosity and photopolymerizable resin that acts by capillarity. This technique is easy to apply and does not lead to post-operative sensitivity. However, clinical cases should be thoroughly evaluated to assess the need for prior microabrasion or macroabrasion, as well as the need to subsequently add a composite to obtain satisfactory aesthetic results. Conclusion: Based on the satisfactory results obtained in both cases, we conclude that the resin infiltration technique is very promising and could be considered as a minimal invasive procedure. However, long term follow-up evaluation must be carried out to affirm the efficacy and durability of this type of treatment.
