Background: Glass ionomers are widely used for restoring carious primary teeth. However, their ability to bond to primary dentin is considered a challenge in pediatric dentistry.

Objectives: The study aimed to evaluate the microshear bond strength (μSBS) of a resin-modified glass ionomer (RMGI) and a high-viscosity glass ionomer cement (Hv-GIC) to primary dentin using a universal adhesive.

Background: Severe early childhood caries (S-ECC) is a multifactorial transmissible infectious disease continuing to affect infants and toddlers worldwide. Saliva plays a modulatory role in the pathogenesis of dental caries.

Objectives: The present study aimed to assess the salivary levels of proteinase-3 (PR3) and interleukin-8 (IL-8) as pro-inflammatory cytokines related to the function of neutrophils in association with S-ECC and its treatment.

Background: Dental caries is initiated through mineral dissolution by bacterial acids and collagen degradation by endogenous proteolytic enzymes, mainly collagenolytic matrix metalloproteinases (MMPs).

Objectives: The present research aimed to evaluate the relationship between severe early childhood caries (S-ECC) and salivary MMP-8 and MMP-20 concentrations.

Material And Methods: Fifty children aged 36-60 months were assigned to either the caries-free (control) group or the S-ECC group.

Background: Considering the high prevalence of vitamin D deficiency and its effect on growth and development, the assessment of the dental age and skeletal age with regard to vitamin D deficiency status could influence the treatment planning of growth modification treatment. This study aimed to assess the relationship between vitamin D deficiency, cervical vertebral maturation (CVM) as an indicator of skeletal age, and dental age in adolescent patients.

Methods: In this cross-sectional study, the chronological age of 52 orthodontic patients aged between 10 and 14 years was recorded, and their serum level of vitamin D was determined using a radioimmunoassay test.

Background: The inclusion of herbal antibacterial agents in the composition of toothpastes is becoming increasingly popular, due to lower side effects. The present study intended to investigate the antibacterial efficacy of a herbal toothpaste containing Bamboo salt on cariogenic oral bacteria.

Methods: The present double-blinded parallel randomized controlled clinical trial was conducted on 60 dental students (age range: 18-30).

Fissure sealant application is an efficient method for dental caries prevention. Self-etch fissure sealants (SE-FS) eliminate the separate etching step for bonding. The present study investigated the micro-shear bond strength (μSBS) of a SE-FS (Prevent seal®, Itena©, Paris, France) to enamel pretreated with different methods including Er,Cr:YSGG laser, under noncontaminated and saliva-contaminated conditions.

The purpose of this study was to compare the efficacy of nanohydroxyapatite (NHA), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and calcium sodium phosphosilicate (NovaMin®) in remineralization of early enamel lesions and compare enamel surface changes using a scanning electron microscope (SEM). Thirty human premolars were sectioned into halves and randomly assigned to five groups (control, demineralization, NHA, CPP-ACP, NovaMin®; equals 12). Ten samples in each of the three test groups were demineralized and treated with their designated paste for two minutes in 24-hour intervals for 30 days.
