“…Composite restorations are toothcolored, can be executed in conservative tooth preparation forms, and have shown good performance in controlled clinical trials. [2][3][4][5][6][7][8][9][10][11] Modern bonding technology has extended the application of composites, reducing microleakage and postoperative sensitivity.12J3 Although the success:failure rate of posterior composites has been well documented, results vary according to the material used and the period e v a l~a t e d .~J~~'~J~ When properly indicated and executed, the annual failure rate of resinbased composite restorations is comparable to the annual failure rate for non-gamma-2 amalgam restorations evaluated for a similar observation period.l6-l8 However, the clinical performance history of amalgam restorations is still superior to that of posterior composite restorations.

“…[2][3][4] The following are the three main reasons why restorations are replaced: Clinician factors, material properties, and patient factors. 2,5 The longevity of dental restorations is influenced by several factors, including the restorative materials used, 6-8 the clinician's expertise, 9 patient's age, 9 the type of tooth, 10,11 the tooth's position in the dental arch, [11][12][13] the restoration's design and size, [12][13][14] and the number of restored surfaces. [14][15][16] Burke et al 17 found that normal occlusal function is associated with increased restoration's age at replacement and that excessive and high occlusal function is associated with reduced restoration's age at failure.…”

“…This finding is consistent with various studies conducted to evaluate restorative failure over the years. 2,3,[5][6][7][8][9][10][11][12] Poor framework/ design was reported as the major cause for RPD failure. Technical failures and complications are caused by faults introduced during the manufacturing process, inappropriate design, or simply due to the amount of time the RDP was in function.…”

Introduction The effect of Khat and Shammah habits, with the parafunctional jaw activities that accompany them, on the integrity of the natural dentition, dental restorations, and prostheses has not yet been investigated. This study is the first attempt to identify the patterns of restorative failure among Khat chewers and Shammah users in Jazan City, Kingdom of Saudi Arabia. Materials and methods A cross-sectional study was conducted in 294 recruits among dental clinics in Jazan City, Kingdom of Saudi Arabia, from October 1, 2015, to April 30, 2016. The patients were surveyed and examined to identify the type of restorations/prosthesis they had and their failures. Bivariate analysis was conducted to investigate the association of the restorative failure with the demographic variables. General linear model was performed to investigate the association between restorations/prostheses failure and Khat/Shammah use with the controlling factors of age and gender as independent variables. Results Khat/Shammah use was statistically significantly associated with restorative failure (p < 0.05) relative to amalgam, composite, crowns, fixed partial dentures, removable partial dentures, and complete dentures. In addition, a significant association of restorative failure was observed with gender, education, and brushing. Conclusion Consumption of Khat/Shammah may be attributed as one of the reasons associated with restorative failure among the Saudi population.

“…Despite reports of good clinical longevity, there are some inherent problems with composite restorations, including polymerization shrinkage and lower wear resistance. [1][2][3][4][5] Polymerization shrinkage appears to be the most significant problem with composite restorations, as it has the potential to initiate gap formation at the tooth-composite interface, 6 which can lead to microleakage, 7 marginal discoloration, 8 secondary caries 9 and eventual failure of the bond. 10 Posterior resin composites can be processed by two methods, 11 either by directly placing the composite in increments, then curing each increment or by indirectly preparing an inlay from the composite, curing it outside the oral cavity and luting it into the cavity with the help of dual cure resin-based cement.…”

Indirect composite restorations have better marginal adaptation than direct composite restorations, and cyclic loading has a more deteriorating effect on the marginal adaptation and microtensile bond strength of direct composite restorations than indirect composite restorations. SUMMARYThis study evaluated the effect of cyclic loading on the marginal adaptation and microtensile bond strength of direct vs indirect Class II composite restorations in an in-vitro model. Forty Class II cavities were prepared on the mesial surface of extracted human maxillary first premolars and divided into two groups: Group I-direct composite restorations and Group II-indirect composite restorations. Groups I and II were further divided into subgroups: A (without cyclic loading) and B (with cyclic loading of 150,000 cycles at 60N). The gingival margin of the proximal box was evaluated at 200x magnification for marginal adaptation in a low vacuum scanning electron microscope. The restorations were sectioned perpendicular to the bonded surface into 1 mm thick slabs. The slabs were further trimmed at the interface to produce a cross-sectional surface area of approximately 1 mm 2 . All specimens were subjected to microtensile bond strength testing. The marginal adaptation was analyzed using descriptive studies and bond strength data were analyzed by one-way ANOVA test. The indirect composite restorations performed better under cyclic loading.Vivek Aggarwal, MDS, senior resident,
