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 results of this trial failed to demonstrate superiority of one treatment modality over the other. GTR outcomes in this trial were lower than anticipated based on previous evidence. This was attributed to the high prevalence of post-surgical complications in the GTR group.

The results and conclusions of the reviews were presented in the following papers: Van Assche et al. (2012) Accuracy of computer-aided implant placement. Hultin et al. (2012) Clinical advantages of computer-guided implant placement: a systematic review. Wennström & Derks (2012) Is there a need for keratinized mucosa around implants to maintain health and tissue stability? Wang & Lang () Ridge preservation after tooth extraction. The group's consensus statements, clinical implications and implications for future research are presented in this article.

The DL and NK10% gel were proven effective in the treatment of DH. A significantly greater immediate response was observed with DL.

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.
