Ti allergy can be detected in dental implant patients, even though its estimated prevalence is low (0.6%). A significantly higher risk of positive allergic reaction was found in patients showing post-op allergy compatible response (ACRG), in which cases allergy tests could be recommended.

The use of PDT, especially counter-rotational and oscillating-rotating brushes, can be beneficial in reducing the levels of gingival bleeding or inflammation. There is a need for methodological homogeneity in future studies in this field to enable quantitative analysis of their results.

A greater reduction of DH after ES was observed after 48 h of treatment in the NK10% group (35.8%) compared to the NK5% group and placebo group (11.8% and 13.4%, respectively). This difference increased significantly at 96 h (p=0.003). No significant differences were observed for the other variables. These preliminary results may support the usefulness of an NK 10% gel to reduce the DH after stimulation with a blast of air during the first 4 days of its appearance.
