Clinical and radiographic evaluation of low-level laser therapy in primary teeth pulpotomy treatment: a randomized clinical trial

Aim. The aim of this study was to compare the effectiveness of diode laser and low-level laser therapy (LLLT) in primary pulpotomy treatments with deep dentinal caries. Materials and methods. The study comprised 90 patients (42 females and 48 males) aged 6–9 years with deep dentin caries in the lower second molar. The patients were assigned to the following treatment groups: the diode laser group (n^S= 45) or the LLLT group (n^S= 45). The appointments were scheduled 3, 6, and 12 months after the treatment, and both clinical and radiographic follow-ups were performed. Results. The diode laser group had a clinical success rate of 95.6% and a radiological success rate of 93.3% at 12 months, while the LLLT group had a clinical success rate of 97.7% and a radiological success rate of 90.9%. There were no statistically significant differences in the success rates of the two groups. Conclusions. LLLT+CH may be a good treatment alternative for pulpotomy instead of devital diode laser pulpotomy.
