AIM The aim of this study was to examine clinically relevant data on four restorative procedures for non-carious cervical lesions using United States Public Health Service (USPHS)-compatible clinical and photographic criteria and to compare different methods of analyzing clinical data. METHODS AND MATERIALS Fourteen patients with at least one or two pairs of non-carious lesions under occlusio...

PURPOSE This study was performed to compare the clinical performance between the compomer F2000 and amalgam Dispersalloy in Class II restorations in primary molars over a 2-year period. METHODS Seventy-five amalgam and 75 compomer restorations were placed in 75 children based on a split-mouth design. The restorations were evaluated after 1 week and after 6, 12, 18, and 24 months of oral funct...

Fracture and secondary caries are the primary reasons for the failure of dental restorations. To face this omnipresent problem, we report the formulation design and synthesis of a protein-resistant dental composite composed of 2-methacryloyloxyethyl phosphorylcholine (MPC) that also can self-repair damage and recover the load-bearing capability via microencapsulated triethylene glycol dimethacr...

OBJECTIVE This study evaluated the 56-month clinical performance of Class I and II resin composite restorations. Filtek P60 was compared with Filtek Z250, which are both indicated for posterior restorations but differ in terms of handling characteristics. The null hypothesis tested was that there is no difference in the clinical performance of the two resin composites in posterior teeth. MATE...

Available evidence indicates that infants, for the most part, acquire their oral flora, in particular Streptococcus mutans, from their mothers. The purpose of this study was to explore the effect of rampant caries in rat dams on subsequent caries activity in their offspring. Rampant caries was induced by surgical desalivation of four dams, and subsequent infection with Streptococcus sobrinus 67...

One of the primary causes for the failure of glass ionomer cement (GIC) is secondary caries. To enhance the anti-microbial performance of GIC without affecting its mechanical properties, chlorhexidine (CHX) was encapsulated in expanded-pore mesoporous silica nanoparticles (pMSN) to synthesize CHX@pMSN. CHX@pMSN was added at three mass fractions (1%, 5%, and 10% (w/w)) to GIC powder as the exper...

OBJECTIVE To evaluate the 12-month clinical performance of conventional (Compoglass F) and colored (Twinky Star) compomer restorative materials in class II restorations of primary molars. MATERIALS AND METHODS A total of 196 restorations were placed in 98 children aged between 5 and 10 years (mean age: 7.43 +/- 1.31 years) who had bilateral matched pairs of carious posterior class II primary ...

This study investigated the effect of silver diamine fluoride (SDF) and potassium iodide (KI) treatment on secondary caries prevention and tooth discolouration in glass ionomer cement (GIC) restoration. Cervical GIC restorations were done on 30 premolars with: Group 1, SDF + KI; Group 2, SDF (positive control); Group 3, no treatment (negative control). After cariogenic biofilm challenge, the de...

Secondary caries are a worldwide public and socioeconomic problem. The placement of restorations can lead to the development of environmental conditions favorable to microbial colonization, especially on the tooth/restoration interface, which is a predisposing factor for secondary caries. The aim of this study was to evaluate microbial retention on conventional (Chelon-Fil and Vidrion R) and re...

OBJECTIVE To investigate the longevity and reasons for failure of posterior cast Class II gold inlays and onlays among a group of Norwegian adults. The term inlay was used for both inlays and onlays. METHODS A cohort of 138 patients regularly attending a general practice for check-up were examined in 2016. The patients had a total of 391 posterior gold inlays placed in the period 1970-2015. T...
