Article Abstract
Root caries is a form of decay affecting root surfaces of teeth, often exacerbated by periodontal disease, reduced salivary flow, and compromised mucosal health, all factors strongly influenced by nutrition. Despite this connection, few studies have addressed the role of vitamins in oral health. This study examines the association between serum levels of alpha-carotene (α-carotene), a potent antioxidant and proxy for vitamin A, and the experience of root caries. Using data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES), we conducted a cross-sectional analysis and applied a weighted multiple logistic regression model, adjusting for potential confounders including age, sex, education level, race, income-to-poverty ratio, and presence of gum disease. Higher serum α-carotene levels were inversely associated with root caries. Each unit increase in serum α-carotene was associated with a 9% decrease in the odds of having root caries (OR = 0.91; 95% CI: 0.86-0.97; = 0.004). In this nationally representative sample of U.S. adults, lower serum α-carotene levels were associated with a higher prevalence of root caries. These findings highlight the potential role of nutritional assessment and integration in oral health. Longitudinal and mechanistic studies are needed to confirm and further explore α-carotene's effects on oral health.

Managing root caries with silver diamine fluoride, sodium fluoride and direct restorations: A cost-effectiveness analysis.
J Dent
September 2025
Faculty of Dentistry, National University of Singapore, Singapore; Saw Swee Hock School of Public Health, National University of Singapore, Singapore.
Objective: To assess the cost-effectiveness of silver diamine fluoride (SDF) relative to sodium fluoride (NaF) and traditional resin-modified glass ionomer cements (RMGIC) restorations for the management of root caries in older adults aged 60 and above.
Methods: A Markov model design was chosen and two models were constructed: 1) Clinic-based model - with access to dental facility that allows for placement of traditional restorations, 2) Community-based model - without access to dental facility due to mobility, lack of executive function, or financial barriers. Modelling was done over a 10-year time horizon with a cycle length of one year.
[Clinical study on hemodynamics and analgesic effect of local infiltration anesthesia in the treatment of severe early childhood caries under general anesthesia].

State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, National Clinical Research Center for Oral Diseases, Shaanxi Oral Bioengineering Technology Research Center, Dept. of Pediatric Dentistry, School of Stomatology, The Fourth Military Medical University, Xi'an 710032, China.
Objectives: This study aimed to explore the clinical efficacy of severe early childhood caries (SECC) treatment combined with local anesthesia under general anesthesia.
Methods: A total of 108 children under 6 years old who underwent SECC dental treatment under general anesthesia at the Department of Pediatric Dentistry, Third Affiliated Hospital of Air Force Medical University from March to December 2023 were selected as the study subjects, with American Society of Anesthesiologists (ASA) classification of classⅠor Ⅱ. The study subjects were divided into a control group (=54) and an experimental group (=54) by retrieving intraoperative cases and postoperative follow-up records.

Graduate Program in Dentistry, Federal University of Pelotas, Brazil. Electronic address:
Objective: This systematic review evaluated the most effective strategy for the topical application of fluoride in arresting active root caries lesions in adults and elderly patients.
Methods: Databases were searched to identify randomized controlled trials (RCTs) involving adults or elderly patients who presented carious lesions on the root surface of permanent teeth and were exposed to any strategy for the topical application of fluoride. The outcome considered was the arrest of root carious lesions.
