The current use of anti-cariogenic agents and fluoride agents to cure write spot lesion: A systematic analysis.

J Pak Med Assoc 2019 Dec;69(12):1876-1882

Margalla Institute of Health Sciences, Rawalpindi.

To find the best option to treat White Spot Lesion in existing caries treatments, and to identify the selected articles discussing etiology of caries along with White spot lesion. Null hypothesis was that "Only anticariogenic agent can cure White Spot Lesion". PRISMA guidelines were used to conduct the systematic analysis. An electronic customized search was performed using mesh terminologies on PubMed database based on inclusion criteria that included studies with; any treatment option that can treat or prevent WSL; and minimally invasive treatment options that may be altered to treat WSL. While exclusion criteria comprised studies with treatment of rampant caries, severe early childhood caries and root caries. Inclusion criteria for etiological factors incorporated studies with factors that lead to white spot lesion or carious lesion. Finally, therapeutic agents of dental caries were analyzed. Only the use of anti-cariogenic agent cannot cure White Spot Lesion. Hence study fails to prove the null hypothesis. Although combination of anti-cariogenic agents with a re-mineralizing agent can provide additional options for the treatment or prevention of WSL.

Comparative abrasive wear resistance and surface analysis of dental resin-based materials.

Eur J Dent 2018 Jan-Mar;12(1):57-66

Department of Restorative Dental Sciences, College of Dentistry, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia.

Objective: The objective of this study was to assess the surface properties (microhardness and wear resistance) of various composites and compomer materials. In addition, the methodologies used for assessing wear resistance were compared.

Materials And Methods: This study was conducted using restorative material (Filtek Z250, Filtek Z350, QuiXfil, SureFil SDR, and Dyract XP) to assess wear resistance. A custom-made toothbrush simulator was employed for wear testing. Before and after wear resistance, structural, surface, and physical properties were assessed using various techniques.

Results: Structural changes and mass loss were observed after treatment, whereas no significant difference in terms of microhardness was observed. The correlation between atomic force microscopy (AFM) and profilometer and between wear resistance and filler volume was highly significant. The correlation between wear resistance and microhardness were insignificant.

Conclusions: The AFM presented higher precision compared to optical profilometers at a nanoscale level, but both methods can be used in tandem for a more detailed and precise roughness analysis.
