The causes of adhesive direct dental restorations failures
Romanian Journal of Stomatology, 2023 The modern dental caries adhesive direct restoration requires a working protocol that includes stages and techniques that must be strictly followed to ensure the correct morphological and functional reconstruction, as well as an increased longevity of the restoration and implicitly of the respective tooth in the oral cavity. Failures in achieving these

Restoration in primary molars placed by undergraduate dental students: reasons for failures
IIUM Journal of Orofacial and Health Sciences, 2021 Dental caries is one of the most common chronic childhood diseases and highly prevalent in the world. The commonest treatment procedure for dental caries is a dental restoration which aims to retain the tooth. The survival of restoration depends on the factors associated with restorative materials, patients or operators.

Longevity of posterior dental restorations and reasons for failure [PDF]
European Journal of Oral Sciences, 2012 Tooth‐coloured restorative materials are being used increasingly more often in Class II preparations in permanent teeth. Using a practice‐based study design, we aimed to assess the survival time of Class II restorations and to identify factors relevant to their longevity.

Evaluation of marginal failures of dental composite restorations by acoustic emission analysis
Dental Materials Journal, 2013 In this study, a nondestructive method based on acoustic emission (AE) analysis was developed to evaluate the marginal failure states of dental composite restorations. Three types of ring-shaped substrates, which were modeled after a Class I cavity, were prepared from polymethyl methacrylate, stainless steel, and human molar teeth.

The failure of amalgam dental restorations due to cyclic fatigue crack growth. [PDF]
Journal of materials science. Materials in medicine, 1999 In this study a restored mandibular molar with different Class II amalgam preparations was examined to analyze the potential for restoration failure attributed to cyclic fatigue crack growth. A finite element analysis was used to determine the stress distribution along the cavo-surface margin which results from occlusal loading of each restoration. The
