Does the Transillumination Technique Using a Diagnostic White Tip Influence the Degree of Conversion of the Infiltrant Resin? A Case Report With In Vitro Insights: A New Technique to Improve the Predictability During the Application of Resin Infiltration: Transillumination Using a Diagnostic White Tip.

OBJECTIVE

This study aimed to evaluate, through a case report combined with in vitro study, whether a new diagnostic white tip for the transillumination technique during resin infiltration influences the procedure and degree of conversion (DC).

MATERIALS AND METHODS

A clinical case report demonstrated resin infiltration using the transillumination technique with a new white diagnostic tip (Radii Xpert LED diagnostic tip, SDI, Bayswater, VIC, AU) along with a light-curing device to enhance aesthetic results. An in vitro study assessed the DC of two diagnostic white tips (Radii Xpert LED diagnostic tip [SDI, Bayswater, VIC, AU] and Valo Grand White Light Lens [Ultradent Prod., South Jordan, UT, USA]) compared to that achieved using conventional tips of both light-curing devices. Statistical analysis was performed using two-way ANOVA and Tukey's test (α = 0.05).

RESULTS

The clinical case achieved complete masking of the white spot lesion. In vitro, the diagnostic white tips exhibited significantly lower DC values compared to conventional tips (p = 0.001), regardless of the light-curing unit.

CONCLUSIONS

The diagnostic white tip used in the transillumination technique improves resin infiltration visibility without compromising the degree of conversion.

CLINICAL SIGNIFICANCE

The transillumination technique with the diagnostic white tip enables monitoring of resin infiltration while maintaining effective polymerization.
