According to a recent study, Silver diamine fluoride (SDF) and Nano Silver Fluoride (NSF) after 6 months exhibited significant enhancements in children's Oral Health-Related Quality of Life (OHRQoL). It was observed that NSF had a significantly superior impact on OHRQoL compared to SDF. This study’s results were published in the Journal of dentistry.

This study involved 360 children under the age of 4, each having at least one active lesion with an International Caries Detection and Assessment System (ICDAS) score of ≥3. They were randomly divided into two groups: one receiving NSF at the beginning, and the other receiving SDF at the start and after 6 months. The Oral Health-Related Quality of Life (OHRQoL) was assessed using the Arabic version of the Early Childhood Oral Health Impact Scale (A-ECOHIS). Additionally, group comparisons were made using the chi-square test, and the impact of the intervention on OHRQoL was analyzed through multiple linear regression.

In the bivariate analysis and regression analysis (B= -5.02) with confounder adjustments, it was observed that NSF exhibited significantly lower A-ECOHIS scores compared to SDF after a period of 6 months. Both groups showed significant decreases in the A-ECOHIS domain and total scores, except for the social interaction domain in the SDF group.

The above study demonstrated that after a 6-month period, both NSF and SDF led to a significant improvement in children's OHRQoL. However, NSF had a notably greater impact on OHRQoL compared to SDF.

According to a recent study, the bioactive glass-ceramic (HX-BGC) and NovaMin toothpaste exhibited more significant effects in addressing dentinal hypersensitivity when compared to the negative control group. No adverse reactions associated with the experimental toothpastes were noted. This study’s research findings were published in the Journal of Dentistry.

In this single-center, randomized, double-blind study, participants were randomly allocated to use one of the HX-BGC, NovaMin, or negative control toothpastes. Follow-up examinations were conducted immediately after a single use and at 2 weeks, 4 weeks , and 6 weeks. Schiff and Yeaple indices were used for intra-group and inter-group comparisons. The safety of the experimental toothpastes was evaluated through participant feedback and oral soft tissue examinations.

There was an increase in Yeaple indices across all groups, with significant differences noted between the HX-BGC group and the other two groups after a continuous 2-week period of use. Schiff indices decreased in all groups, with the NovaMin group demonstrating significant differences when compared to the negative control group. Significant improvement was observed in both the HX-BGC group and the NovaMin group by weeks 4 and 6 compared to the negative control group in both indices. The HX-BGC group exhibited better results in the Yeaple index compared to the NovaMin group. Additionally, no serious adverse reactions related to the toothpastes were reported or observed among the participants.

The above study confirmed the efficacy of HX-BGC in treating dentinal hypersensitivity and supported the clinical use of dentifrices formulated with HX-BGC. Both the HX-BGC and NovaMin toothpaste groups exhibited significantly greater efficacy in managing dentinal hypersensitivity compared to the negative control group. There were no adverse reactions reported in relation to the experimental toothpastes.

In a recent study, it was found that two types of remineralising toothpastes show promising results in reducing dental sensitivity and periodontal indices and may be suitable for children with asthma and allergic rhinitis to use at home. This study’s findings were published in the European Journal of Paediatric Dentistry.

For this study, a total of 40 patients between the ages of 6-14 years, who had enamel demineralisations, were included. Several indices were collected such as, Schiff air index (SAI), bleeding on probing (BoP), plaque index (PI), susceptibility index (SI), Basic Erosive Wear Examination (BEWE) for soft and hard tissues pathologies, salivary pH, and decayed missing filled teeth (DMFT). Following mechanical debridement with piezoelectric instrumentation and glycine powder, patients were evenly divided into two groups: group 1 used a zinc hydroxyapatite toothpaste, whereas group 2 used a calcium sodium phosphosilicate toothpaste. Both groups were instructed to use the toothpaste twice a day. The study was conducted over the following time frames: baseline (T0), after one month (T1), after three months (T2), and after six months (T3).

Significant intragroup differences from the beginning to the end of the study were observed for the variables PI, BOP, and SAI (p < 0.05). Upon analysing SI, group 1 exhibited significant intragroup variances when comparing each time frame with T3 (p < 0.05).

It can be concluded that the two remineralising toothpastes significantly reduce dental sensitivity and periodontal indices, suggesting that they may be suitable for children with asthma and allergic rhinitis to use at home.

A recent study found that the prevalence of dentin hypersensitivity (DH)/toothache was 22% per tooth and 45% per patient globally. The prevalence estimates differed depending on the diagnostic methods utilized. Individuals with Molar-Incisor Hypomineralization (MIH) were more prone to presenting proxy reports of DH or toothache compared to the controls. This study’s results were published in the Journal of Dentistry.

The studies that were included in the evaluation focused on DH/toothache in patients with MIH, while those that centered on other enamel defects were excluded. In January 2024, a comprehensive search was conducted across eight databases, including grey literature. The Joanna Briggs Institute checklist for Cross-sectional studies was used to assess the methodological quality of the studies. Meta-analyses on proportion and association, subgrouped by diagnostic methods, were performed. The GRADE approach was utilized for the assessment of the certainty of the evidence.

In the qualitative analysis, fifteen studies were included, and fourteen were included in the meta-analyses. Two studies met all the criteria in the methodological quality checklist. The overall prevalence of DH/toothache among individuals with MIH was 45%. Prevalence rates of 47%, 30%, and 55% were estimated based on self-reports, proxy reports, and air stimulation, respectively. The overall prevalence of DH/toothache per tooth was 22%, with a range from 16% to 29% depending on the diagnostic method utilized. Individuals with MIH were more likely to present proxy reports of DH/toothache when compared to individuals without MIH (OR: 1.51; 95% confidence interval (1.23-1.85); P < 0.01; I²: 0%). Due to the low methodological quality of the studies included and high inconsistency, the certainty of evidence was very low.

Thus, it can be concluded that the prevalence of dental hypersensitivity/ toothache was 22% per tooth and 45% per patient worldwide and the prevalence estimates differed based on the diagnostic techniques used. Individuals with MIH were more likely to present proxy reports of DH or toothache compared to the controls.
