Dental cavity liners for Class I and Class II resin-based composite restorations

Abstract

Eight studies, with over 700 participants, were included. Two studies were conducted in the USA, two in Thailand, two in Germany and one each in Saudi Arabia and Turkey. The studies compared the use of liners under tooth-colored resin fillings (RBC) in permanent teeth at the back of the mouth to no liners for Class I and Class II fillings. One of the two studies in the USA took place in dental practices, the others in university-based dental schools. All participants were over 15 years of age. Key results Very little evidence was found to show that a liner under Class I and II RBC fillings in permanent teeth in the back of the mouth reduced sensitivity in adults or children 15 years or older. No evidence was found to show that there was any di erence in the length of time fillings lasted when placed with or without a cavity liner. No adverse events were reported in any of the included studies. Quality of evidence The body of evidence identified in this review does not allow for robust conclusions about the e ects of dental cavity liners. The quality of the evidence identified in this review is low and there is a lack of confidence in the e ect estimates. Furthermore, no evidence was found to demonstrate a di erence in how long restorations last when placed with or without dental cavity liners.

Effect of a Self-Etch Adhesive Containing Nanobioglass on Postoperative Sensitivity of Posterior Composite Restorations - A Randomized Trial

“…Resin composite restorations in the current study were placed directly in posterior teeth without the use of liners and bases in accordance with a systematic review [24] that linked the use of liners to the reduction in postoperative sensitivity, they revealed that there is an inconsistent evidence regarding the difference in POS between resin composite restorations placed with or without liners. Resin composite was placed using an incremental filling technique and indirect curing through the cusps, to minimize the deleterious effects of polymerization shrinkage stresses on the marginal integrity of the composite restorations as well as on the microscopic integrity of the adhesive bond to dentin [22].…”

Treatment preferences for deep caries lesions among Australian dentists

“…27,29 While there was a general preference among respondents of the current study to place a liner, a recent systematic review has shown that the evidence is inconsistent in terms of postoperative sensitivity with use of liners under resin-bonded restorations. 13 Another recent systematic review on whether calcium hydroxide liner is required for deep caries lesions confirmed these findings that treatment of the deep caries lesion is not a material-dependant technique. 30 This is also in line with the latest consensus recommendations which stated that there is no evidence to recommend a specific material.…”

“…[10][11][12] Furthermore, although traditional teaching advocates placement of a liner in deep caries lesions, particularly under metallic restorations such as amalgam, their role has recently been questioned. 13 The placement of a liner neither improves the longevity of the restoration 13 nor does it reduce the pulpal complications. 14 There is limited information on the attitudes and behaviour of Australian dentists to deep caries lesions.…”
