What significant finding is reported in studies using Nd:YAG laser for periodontal treatment?

The significant finding associated with the use of Nd:YAG laser for periodontal treatment is the histological confirmation of bone regeneration. Research has shown that Nd:YAG lasers can promote healing and regeneration in periodontal tissues. This includes stimulating the surrounding cells and enhancing the biological responses necessary for tissue repair and regeneration.

Clinical studies have provided evidence that the application of Nd:YAG lasers during periodontal therapies not only helps in reducing bacterial load but also supports the regeneration of bone and periodontal structures. The ability to demonstrate histological changes that indicate new bone formation is essential, as it suggests that the treatment may lead to improved clinical outcomes compared to traditional methods.

Other options do not adequately capture the benefits of Nd:YAG laser usage in periodontal therapy. For instance, stating that there is no impact on regeneration overlooks the critical findings that support bone healing. Similarly, describing the results as only cosmetic improvements or limited to surface cleaning undermines the laser's biological effects and the potential for genuine tissue regeneration associated with proper treatment protocols. Therefore, the histological confirmation of bone regeneration highlights the effectiveness of Nd:YAG lasers in achieving meaningful periodontal treatment outcomes.
