Advancement of dental restoration technique and reviewing the related benefits to Periodontium, dental implant treatments, bone grafts and orthodontic treatments

Micro-leakage and secondary caries post dental restoration are considered as broad challenges in dental treatments, and it happens when microbes, molecules, and liquids penetrate between the two surfaces of the tooth tissue and the restorative materials. This may result in tooth sensitivity, pulpitis, periodontal diseases and etc. Therefore, based on this importance, the effect of time duration and surface coating on micro-leakage in Class V restorations, by using bulk-fill composites has been examined. It was clearly shown that the surface coating has the ability to reduce micro-leakage to a great extent. The duration in the process of treatment had no significant effect on micro-leakage, but the type of treatment method was able to significantly reduce micro-leakage in the occlusal walls.  Furthermore, it was found that it is more preferable to perform the polishing and finishing process with a polishing disk without using a burr.

Since micro-leakage causes complications in other oral organs and tissues, especially adjacent tissues, it may involve other dental filds, including periodontics, orthodontics, oral and maxillofacial surgery and etc, in addition to restorative dentistry. Hence accordingly it has been found that by preventing micro-leakage, great steps can be taken in order to maintain the health of the periodontium, achieve greater success in orthodontic treatments, and also reduce the complications related to oral and maxillofacial surgical treatment methods.
