Background/objectives: School-based caries prevention can increase access to critical dental services and reduce oral health inequities. However, little is known regarding the incidence of dental caries in children participating in school caries prevention, and caries diagnosis is often interval censored.

Methods: In this paper, we used data from a longitudinal, school-based, randomized clinical trial of minimally invasive treatments for dental caries to estimate the per-visit incidence rate and compare the hazard of dental caries in children receiving either silver diamine fluoride or glass ionomer dental sealants.

Article Synopsis
  • Dental caries is a widespread issue impacting children's health, particularly in low-income minority populations, prompting the need for effective preventive measures like dental sealants and silver diamine fluoride (SDF).
  • The CariedAway study investigated whether the application of SDF in schools was as effective as traditional dental sealants and atraumatic restorative treatment (ART) in preventing dental caries among children aged 5 to 13 in New York.
  • The study randomized nearly 7,500 eligible students into two treatment groups (SDF or sealants/ART) and tracked their dental health, finding insights that could reinforce preventive dental care strategies for at-risk communities.

Article Synopsis
  • The study aimed to evaluate the effectiveness of a daily group toothbrushing program in Filipino schools against conventional oral health education in reducing dental issues among children over three years.
  • The trial involved three intervention groups focusing on tooth brushing, urgent oral treatment access, and fluoride gel application, with clinical examinations of 682 seven-year-olds occurring at the outset and biannually thereafter.
  • Results showed that while the basic toothbrushing program reduced dental caries by 22%, the combination with fluoride application notably further decreased dental health issues compared to control groups.

The objective of this pilot study was to describe the microbial profiles present in the plaque and saliva of children who continued to develop new carious lesions following treatment with silver diamine fluoride ("nonresponders") compared to caries active, caries-free, and children immediately receiving SDF treatment for untreated caries in order to identify potential microbial differences that may relate to a re-incidence of caries. Saliva and plaque samples from infected and contralateral sites were obtained from twenty children who were either caries free, had active carious lesions, were caries active and received SDF treatment immediately before sampling, or had previously received SDF treatment and developed new caries. In total, 8,057,899 Illumina-generated sequence reads from 60 samples were obtained.

There is currently no criterion to select appropriate bioinformatics tools and reference databases for analysis of 16S rRNA amplicon data in the human oral microbiome. Our study aims to determine the influence of multiple tools and reference databases on α-diversity measurements and β-diversity comparisons analyzing the human oral microbiome. We compared the results of taxonomical classification by Greengenes, the Human Oral Microbiome Database (HOMD), National Center for Biotechnology Information (NCBI) 16S, SILVA, and the Ribosomal Database Project (RDP) using Quantitative Insights Into Microbial Ecology (QIIME) and the Divisive Amplicon Denoising Algorithm (DADA2).

Objectives: The aim of this study was to conduct a systematic review and meta-analysis on the efficacy of growth factors (GF) on clinical outcomes after treatment (surgical/non-surgical) of peri-implant diseases (peri-implant mucositis and peri-implantitis).

Materials And Methods: A protocol was developed to answer the following focused question: Is there any difference for the use of GF for treatment of peri-implant diseases versus comparative GF treatment or without GF? Electronic database and manual searches were independently conducted to identify randomized controlled trials (RCTs). Publications were selected based on eligibility criteria and then assessed for risk-of-bias using the Cochrane Handbook.
