FORCES ACTING ON CLASS-5 RESTORATIONS
1P.A. Vasishta, Jayalakshmi Somasundaram, Vinay Sivaswamy
The main aim of the review is to discuss the forces acting on the class 5 restoration. A thorough literature search was performed using the database like Pubmed, google scholar, BioRxiv, MESH, Cochrane database using the keywords ‘forces’,‘class 5’ and ‘restoration’ with no date and year restrictions. The language is restricted to English. 8 articles with similar data were found which were analysed and have been included in this study. Effect of brushing in class 5 restoration leads to poor esthetics and the person loses the confidence to smile.Vigorous and improper brushing damages the class 5 restoration. Class 5 cavities involve caries affecting the gingival one-third of facial or lingual surfaces of anterior or posterior teeth. Class 5 has only one surface and there is no direct force acting on it, so it is free of mechanical problems. Tooth can withstand force because of resiliency of dentin. Several studies have demonstrated that the use of an adhesive matrix decreases cuspal flexure compared with occlusal amalgam restoration. The depth of an occlusal restoration particularly is more critical than the width. Some instances also showed that the peak stresses were greater than the known bond strengths of composite to dentine.
