The study aimed to investigate the association of varying body mass index (BMI) with oral health status among children aged 5–14 years and correlate the concentration of salivary levels of 1,5-AG with varying BMI, dental caries, and periodontal disease. This cross-sectional study was conducted on subjects aged 5 to 14 years. The children were recruited from the Pediatric Dental Clinic, College of Dentistry, Majmaah University, by convenient sampling method. Sociodemographic details and clinical parameters, including body mass index (BMI), DMFT/def (deciduous decayed tooth (d), deciduous extracted tooth (e), deciduous filled tooth (f), permanent tooth decayed (D), permanent missing tooth (M), and permanent filled tooth (F)), plaque index (PI), and modified sulcular bleeding index (mSBI), were evaluated. Salivary 1,5-anhydroglucitol (1,5-AG) was analyzed using an enzyme-linked immunosorbent assay (ELISA) for all the subjects. Statistical analyses performed using SPSS v. 27 (IBM Statistics, Chicago, IL, USA) and the Kruskal–Wallis and chi-square tests were used for comparisons. The Spearman rank correlation coefficient was used to examine the association between the study subjects’ independent variables, BMI, and caries activity. The mean def score, PI, and mSBI scores were higher in obese children. PI score, mSBI score, and salivary concentrations of 1,5-AG between the BMI categories were statistically significant (p < 0.001). The study emphasizes promoting preventive oral health regimes, health awareness campaigns, and nutritional educational programs among the pediatric population.

The bond strength (BS) and failure status of demineralized dentin following the application of chitosan solution and chlorhexidine (CHX) is of interest to dentists. A total of 30 non-pathological extracted premolar teeth were subjected to caries induction through the pH cycle procedure. The teeth were divided equally into 3 groups as such as group I: control (distilled water), Group II-2.5% chitosan solution and Group III - chlorhexidine (CHX). Later teeth were subjected to a microtensile bond strength test (μTBS). The failure mode was assessed using stereo microscope. The bond strength of the chitosan-treated specimens was significantly higher than that of the chlorhexidine treated specimens and the control specimen which had the lowest bond strength.
