Evaluation of Low Level Laser Therapy in Primary Tooth Pulpotomy Treatment

Clinical and Radiographic Evaluation of Low Level Laser Therapy in Primary Tooth Pulpotomy Treatment

In our study, it was aimed to compare the long-term effectiveness of diode laser and low level laser therapy and primary tooth amputation treatments using calcium hydroxide (LLLT+CH) in primary second molars with deep dentinal caries. Ninety patients ( 42 Gırl, 48 Boy) aged 6-9 years with deep dentin caries in the mandibular second molar were included in the study. The patients were randomly selected according to the treatment to be applied and divided into two groups as the diode laser group (N=45) and the LLLT+CH group (N=45). The patients were called for control appointments at the 1st, 3rd, 6th and 12th months after the treatment, and both clinical and radiographic follow-ups were performed. Chi-square and Fisher's Exact tests were used to compare categorical variables according to groups in statistical analysis, and p<0.05 was considered significant. When the study results at the end of 12 months were evaluated, the diode laser group had a clinical success rate of 95.6%, and a success rate of 93.3% radiologically; The LLLT+CH group had a success rate of 97.7% clinically and 90.9% radiologically. There was no statistically significant difference between the success rates of the groups (p>0.05). According to the clinical and radiographic results of our study, it was determined that diode laser and LLLT+CH amputations showed similar success rates in primary second molars with deep dentin caries. It has been seen that both methods can be used safely in primary tooth amputations. It is thought that clinical and histological studies and studies examining the effectiveness of dental laser applications in primary tooth amputation treatment are needed.
