Decision tree protocol for demineralized gingival margin extension in class II composite cavity preparations

Abstract

Summary This study proposed the development of a protocol for class-II preparations with demineralized gingival margins for the improvement of the longevity of restorations. Evidence sources such as location/color/surface hardness/width of demineralized gingival margin with enamel/demineralized enamel (DE)/dentin/cementum were reviewed based on methodological studies and systematic reviews. A decision tree protocol was developed with criteria (i) lesion location: demineralized gingival margins in enamel must be removed, but if close to cementoenamel-junction, color should be evaluated. (ii) Color: yellow/brown lesions must be removed, but if white/opaque, then the surface hardness should be evaluated. (iii) Surface hardness: soft/demineralized gingival margin must be removed, but if adequately hard, width should be evaluated. (iv) Width: lesions less than half-enamel thickness and impenetrable by an explorer, remineralization is possible and the lesion does not need to be removed. A decision tree protocol was set up with the current available literature. Further continued investigations will be needed for the appropriate protocol updates.

Drug Effect of Loxofen Sodium Tablets on Pain Relief of Periodontal Endodontic Syndrome and its Influence on Inflammatory Factors

“…At present, there is no specific treatment for periodontal endodontic syndrome and there is no specific drug. It is generally believed that bacterial infection is the main cause of periodontal endodontic syndrome [8] . At present, there is no consensus on the molecular dysregulation mechanism of periodontal endodontic syndrome.…”
