“…A detailed description of the microbial-based in vitro caries model has recently been published [17,18]. Briefly, the initially sterilised specimens were inoculated with Streptococcus mutans (ATCC 25175) for biofilm development and incubated in this caries model for 21 days.…”

The study conducted in a bacterial-based in vitro caries model aimed to determine whether typical inner secondary caries lesions can be detected at cavity walls of restorations with selected gap widths when the development of outer lesions is inhibited. Sixty bovine tooth specimens were randomly assigned to the following groups: test group 50 (TG50; gap, 50 μm), test group 100 (TG100; gap, 100 μm), test group 250 (TG250; gap, 250 μm) and a control group (CG; gap, 250 μm). The outer tooth surface of the test group specimens was covered with an acidresistant varnish to inhibit the development of an outer caries lesion. After incubation in the caries model, the area of demineralization at the cavity wall was determined by confocal laser scanning microscopy. All test group specimens demonstrated only wall lesions. The CG specimens developed outer and wall lesions. The TG250 specimens showed significantly less wall lesion area compared to the CG (p<0.05). In the test groups, a statistically significant increase (p<0.05) in lesion area could be detected in enamel between TG50 and TG250 and in dentine between TG50 and TG100. In conclusion, the inner wall lesions of secondary caries can develop without the presence of outer lesions and therefore can be regarded as an entity on their own. The extent of independently developed wall lesions increased with gap width in the present setting.

“…110,111 Moreover, in saliva-contaminated sites, self-etch adhesives or etching were equally unacceptable as the total failure rate was around 60 percent for both materials. 112 This means that, in saliva contamination, RB sealants with or without etching are ineffective, 113 so self-etch adhesives cannot be recommended either for clinical or community sealant projects.…”

Community service-learning (CSL) in predoctoral dental education might be an effective tool for increasing sealant use by dentists-thus benefitting underserved children while facilitating students' learning of a clinical procedure in a real-life setting. This study reviewed the scientific literature on this topic in order to 1) evaluate the reasons for low sealant use among dentists, 2) consider important aspects of sealant use in community settings, and 3) identify best practices to use as guidelines for CSL regarding sealant use. As background, the MEDLINE database was searched with the key words "dental sealants" for human and laboratory studies in the English language. A total of 205 relevant articles were identified and overviewed. We found that the low use of sealants relate to dentists' orientation toward restorations rather than prevention, distrust in sealant treatment, lack of confidence in caries risk assessment, and concern about sealing over caries. The aspects to consider in the CSL projects are acquisition of knowledge and necessary skills of operators, cost-benefit approach to sealant placement, and meticulous sealant placement procedures, including the necessity for a short-term recall.

“…[7] After etching using the air abrasion, a thin layer of Xeno-III applied on the prepared tooth surface and light cured [Figure 10]. [8] Then we applied luting composite to the internal surface of the veneer [Figure 11] and the prepared tooth and removed the excess composite resin with a brush dipped in bonding agent before curing [Figure 12]. [9] Other veneers were placed in same fashion.…”
