Effect of Low-intensity Laser and Photodynamic Therapy on Infected Dentin of Permanent Teeth With MIH

2019-02-06 19:08:27 | BioPortfolio

Summary

The objective of this research was to evaluate the clinical effect of photodynamic therapy on dentin infected by caries lesion in permanent teeth with Molar Incisor Hypomineralization (MIH). The study was composed of Groups (1 and 2). The methodology was based on the selection of patients from 6 to 12 years of age with permanent molar teeth, randomly divided. The selected teeth had deep dentin caries lesions on the occlusal surface, indicated for clinical restorative treatment. Photodynamic therapy was applied with the use of low-intensity laser in permanent teeth selected for the treatment of infected dentin in children who presented pain sensitivity (G1) and without sensitivity (G2). In G1, antimicrobial photodynamic therapy (aPDT) and atraumatic restorative treatment (ART) were made. In G2, only ART was performed. The teeth were restored with high viscosity glass ionomer cement. All patients had clinical and radiographic follow-up with a time interval of 6 and 12 months. Data were submitted to descriptive statistical analysis. For the evaluation of the association of categorical variables like age and gender, the Chi-square test and Fisher's exact test were used. To analyze the correlation between the continuous variables, the Pearson correlation test was applied. ANOVA and Kruskal-Wallis were applied for the analysis of dentin density in the radiographic images scanned and the microbiological results for colony forming units.
