A new randomised controlled study from Dr Omar Marouane et al. has provided groundbreaking insights into the treatment of molar-incisor hypomineralisation (MIH).
The title of the publication is: ‘In vivo comparison of resin infiltration outcomes under different light conditions: A randomized controlled clinical trial’.
The aim of the study was to evaluate whether using transillumination (shining light through the tooth) rather than ambient light enables a more precise estimation to be made as to when the infiltration process is complete and what effect this has on the treatment.
The key findings:
- Improved aesthetic results: Transillumination led to a considerably lower difference in colour between the affected and the healthy tooth areas (∆E = 4.5 vs 7.5) – and to an optimised masking effect.
- Greater infiltration percentage: With transillumination, the amount of infiltration was higher (97.6% vs 83.9%), which increases the effectiveness of the enamel defect treatment.
- Longer treatment time: The higher infiltration percentage was associated with a longer treatment time (17.7 vs 9.3 minutes).
Conclusion: The study shows that transillumination-guided resin infiltration not only enables a more precise assessment of progress but also considerably improves treatment results.
