This review of fissure sealing using flowable composite included 11 studies and suggests retention rates at 1 year may be slightly better than resin-based sealants. However, the findings should be interpreted cautious as the confidence intervals are wide and quality of the studies is limited.

This review of the longevity of posterior restoration in primary teeth included 31 studies. composite resin had the lowest annual failure rate while stainless steel crowns had the highest success rate. The studies all have a high risk of bias so the findings should be interpreted cautiously.

15 RCTs were included in this Cochrane review of Atraumatic Restorative Treatment (ART) comparing with conventional treatment for managing dental caries lesions in the primary and permanent teeth provided low quality evidence that ART using H-GIC may have a higher risk of restoration failure in primary teeth.

This review of inlay-retained fixed dental prosthesis included 11 small mainly observational studies. The studies suggest a 3-yr survival rate of 92.6% (95% CI: 85.8-97.6%) and 5-yr survival rate of 87.9% (95% CI: 77.4-96.1%). However because of the low quality of the available studies and the wide range of inlay designs, framework materials, surface treatments and cement systems used means that the results should be interpreted cautiously.

9 studies were included in this review of fibre-reinforced composites fixed partial dentures. Only 3 of the included studies were prospective and were considered to be moderate quality. Good survival rates were seen at 4-5years.

This review of survival and complication rates of resin-bonded fixed dental prosthesis included 209 studies. The findings suggest overall survival rates of 91.3 % (95%CI; 88–93.7) . The quality of the available studies suggest that this should be interpreted cautiously.

This review of molar-incisor hypomineralisation management only included 14 limited quality and mainly observations studies.For molars composites, preformed metal crowns or indirect restorations seem suitable but more high quality studies are needed.

This review of failure rate of single-unit prostheses versus direct restorations in vital posterior teeth included 14 studies (5 RCTs) finding that composite had a significantly higher failure rate than amalgams, regardless of the remaining tooth structure. For teeth with fewer than 2 remaining walls, direct restorations presented significantly higher failure rates than crowns .

This review of the clinical performance of direct and indirect resin composite restorations in permanent teeth included 9 small RCTs . The findings suggest no difference in clinical longevity but the evidence is limited.

Only 3 RCTs could be identified for this review of the long-term performance of direct versus indirect composite inlays/ onlays in posterior teeth. the limited quality of the studies provide insufficient evidence to recommend direct over indirect techniques.
