Abstract
Purpose: The present clinical investigation aimed to evaluate the effect of low-level laser treatment on the clinical parameters and checking levels of inducible nitric oxide synthase in individuals with stage II periodontitis across various age groups. Materials and methods: The current investigation has been carried out on 40 locations in 40 patients. Randomly selected locations were chosen from each studied case, and divided into four groups: group A consisted of 10 sites in elderly patients who underwent scaling combined with root planning exclusively. Group B included 10 sites in young patients who also got scaling and root planning exclusively, group C 10 sites in old age who received diode laser therapy, and group D: 10 sites in young age group received low-level laser (diode laser). The clinical examination used the following clinical parameters: clinical attachment level, plaque index, and Gingival index. An EnzymeLinked Immunosorbent Assay study was conducted on iNOS. Results: Baseline and 3-month postoperative groups were compared and showed significant differences in iNOS levels which was influenced by the treatment in the young age group (nonsurgical and laser), but showed no significant difference in the old age group on both types of treatment (nonsurgical and laser). Conclusion: This clinical investigation showed that whereas non-surgical techniques in conjunction with low-level laser treatment were unsuccessful in the elderly population, it was helpful in the young group with stage II periodontitis.
