A preferable choice of material offers superior resistance against micro-leakage for clinical applications in preventing dental caries in pits and fissures is of interest. A total of 45 extracted human premolars were cleaned, stored in a saline solution, and randomly divided into three groups, each intended for treatment with one of the sealants: Fuzi VII, ClinPro, and Embrace Wetbond. The application of the sealants followed the manufacturers' instructions strictly. The teeth were subjected to thermal cycling to simulate oral conditions. Marginal micro-leakage was then assessed by dye penetration method using a 0.5% methylene blue dye. Teeth were sectioned, and dye penetration was measured under a stereomicroscope. The results showed that all the tested materials exhibited some degree of micro-leakage. Within the limitations of this study, it was concluded that Embrace Wetbond exhibited superior performance in terms of minimizing marginal micro-leakage among the tested pit and fissure sealants.

Background: Dental caries is one of the most common non-communicable diseases in humans. Various interventions are available for the management, of which microinvasive techniques such as infiltration, sealants, glass ionomers, are novel and convenient. The purpose of this systematic review and meta-analysis was to compare microinvasive techniques with noninvasive or invasive treatment modalities in terms of effectiveness in halting interproximal caries lesion progression radiographically assessed.

Introduction: In the forensic field, having accurate understanding of the macroscopic and microscopic alterations that occur in teeth when exposed to temperatures has remarkable significance. The preservation of delicate incinerated teeth is crucial in fire investigations that pertain to the temperature exposed, as well as the identification of victims. This preservation is necessary in order to conduct macroscopic and microscopic ultra-structural examinations, which provide valuable insights into the structural alterations that dental tissues undergo when exposed to low to high temperatures.

Objective: This cross-sectional study aimed to investigate the use, quality, and caries-preventive effects of fissure sealants (FSs) in 8- to 10-year-olds with and without molar-incisor hypomineralization (MIH).
Materials And Methods: A total of 5,418 children (2,692 males, 2,726 females) were examined via standard instruments (dental mirrors, CPI probes, adequate lighting, mobile examination tables, and air syringes) and methods for the recording of caries (DMFT index, WHO method) and FSs. The classification of MIH followed the recommendations of the European Academy of Pediatric Dentistry (EAPD).
Comparative evaluation of pit & fissure sealant retention using cotton roll & rubber dam isolation techniques - a systematic review & meta-analysis.

Faculty of Dental Sciences, Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India.
Background: Isolation with cotton rolls does not always provide as complete isolation as rubber dam, especially in procedures where absolute moisture control is critical. Therefore, this review aims to summarize and analyze previous studies evaluating the retention and marginal integrity of pit & fissure sealant using rubber dam and cotton roll isolation techniques during dental treatment in children.
Material And Methods: In accordance with PRISMA guidelines, search yielded 1361 articles, with seven RCTs and one non-RCT design meeting the inclusion criteria.

Article Synopsis
- Untreated dental caries is a major health issue, and pit and fissure sealants (PFS) are used to prevent them.
- This study looks at the use of PFS among Mexican adolescents aged 10-14 from 2005 to 2014 and its impact on the decayed, missing, and filled teeth (DMFT) index nationally.
- Results showed low PFS use (1.57%) with no significant trend over the years, but there was a decrease in the DMFT index, which appeared unrelated to PFS usage.
