Resin Infiltration for the Esthetic Improvement of Dental Fluorosis and White Spots: A Case Report

White spot lesions, characterized by opaque enamel discolorations from early carious lesions, fluorosis, or developmental issues, can be effectively managed through various treatments. Resin infiltration is a unique therapy that bridges the gap between non-invasive and invasive alternatives, potentially delaying the need for restorations by applying a low-viscosity resin that penetrates and seals the lesion, enhancing both appearance and function. This study evaluates the clinical and esthetic outcomes of resin infiltration in a 33-year-old female patient with mild dental fluorosis, who presented with white and brown discolorations on her anterior teeth and a high caries index. Following a comprehensive treatment plan that included scaling, root planning, and resin infiltration, several diagnostic tests - such as Endo-Ice, Electric pulp testing, DIAGNOdent, and Spectrophotometer - were utilized to assess treatment success, showing reduced pulp sensory response times, improved caries detection values, and noticeable esthetic enhancements. However, one-month post-treatment, the patient reported yellow staining on the treated surfaces due to turmeric consumption, necessitating additional finishing and polishing. This case underscores the effectiveness of resin infiltration in improving both esthetic and clinical outcomes for fluorosis and incipient carious lesions, emphasizing the importance of patient education regarding dietary habits and oral hygiene to prevent staining and ensure long-term success, while further research is warranted to explore the long-term efficacy of resin infiltration and develop strategies to mitigate post-treatment discoloration.
