Abstract
Background/Aim: The objective of study analysis of the effectiveness of using a laser photodynamic system for the treatment of chronic apical periodontitis.
Materials and Methods: The study included 66 patients aged 18 to 60 years with a diagnosis of chronic apical periodontitis in whom 90 root canals were treated. The diagnosis was established on the basis of the patient's complaints, clinical and instrumental studies, X-ray data.
The patients were divided equally into two groups and underwent endodontic treatment. In the root canals of patients of the first group, disinfection was carried out by the method of photodynamic therapy. Then the canal was obturated with gutta-percha pins and sealer, the tooth was restored. In patients of the 2nd group, after instrumental and medical treatment, the root canals were sealed with a temporary material "Kalasept" (Sweden) based on calcium hydroxide, and the tooth was restored with a temporary glass ionomer cement "Vitremer" (3M ESPE).
process of the rarefaction focus.
Results: The evaluation of the results of treatment was carried out in terms of 1-14 days, 6 and 12 months after the final filling of the root canals. positive dynamics in a short time was observed in 93.9% of patients. cases in patients of the 1st group and in 72.7% in patients of the 2nd group. Complications arose in patients of the 1st group in 6.1% of cases. In the 2nd group in 27.3% of cases, which is almost 4.5 times more than in the 1st group. When comparing 2 methods of treatment after 6 months, clinical well-being was observed in patients of the 1st group in 96.9% and in the 2nd group in 81.8% of cases. The percentage of complications that occurred was 3.1% in patients of the 1st group and 18.2% in the 2nd group.
Complete healing of the focus in the bone tissue was observed in 84.8% of cases in patients of the 1st group and in 66.6% of cases in patients of the 2nd group. Partial healing of the bone tissue focus was observed in 18.1% and 15.1% of cases in the 1st and 2nd groups.
Conclusion: The use of laser radiation in preparing the root canal for obturation in the treatment of chronic forms of periodontitis made it possible to reduce the number of complications by almost 1.5 times and accelerate the healing process of the rarefaction focus.
