The Xylitol Applicability and its Effects in Health Area Worldwide: A Bibliometric Analysis Based on Randomized Controlled Trials

Abstract

Objective: To describe and evaluate the xylitol products' applicability and its effects in the health area worldwide utilizing a bibliometric analysis from randomized controlled trials (RCT) with humans. Material and Methods: Electronic searches were carried out in Medline/PubMed, Scopus, Cochrane Library, Web of Science, and VHL databases. The main data extracted were: year, area of applicability, type of treatment, country, journal, xylitol posology and concentration, presentation form, outcomes, and effects. Results: From 1476 studies, 257 were included. These studies were published between 1973-2021. The majority was carried out in dentistry (73.9%) and under preventive treatment (67.4%). These studies were developed in the USA (15.4%) and published in Caries Research (6.6%). The posology and concentration ranged between 0.004-67 g/day and 0.002-100%, respectively. The xylitol is usually used in the chewing gum form (44.0%), and for antimicrobial activity evaluation (38.5%). A positive effect was observed in 204 studies (79.3%) and was associated with xylitol concentration ≥ 15% (p=0.007). Side effects were reported in 8.2% and were associated with posology ≥ 5 g/day (p=0.03). Conclusion: Most studies with xylitol were conducted to prevent diseases in the dentistry field. The chewing gum form and antimicrobial activity evaluation were more frequent. Most xylitol products have a positive effect, and few studies report side effects.

Sugar Alcohol: A Comparison of Xylitol and Sorbitol in Food Application

“…Xylitol is a five-carbon polyol (sugar alcohol), with a low-calorie and crystalline structure (Martins et al, 2022). The presence of five hydroxyl groups allows xylitol to have a great affinity for water, which allows it to be soluble in solutions (Arcaño et al, 2020).…”

Vitamin D Deficiency in Childhood: A Review

“…Under a vitamin D supplementation program, the prevalence of rickets in children under three years old in Turkey dropped from 6% to 0.1% [49][50][51]. Recent research has investigated the correlation between low levels of 25-hydroxyvitamin D and the quality of bones, occurrences of fractures, and changes in body measurements in children who are in good health [52].…”

“…Pregnant women with a vitamin D deficiency are also more likely to experience complications such as pre-eclampsia, early delivery, and gestational diabetes. To assess a pregnant woman's vitamin D status, doctors measure her levels of a protein called vitamin D binding protein (VDBP) [52,53]. A preliminary Infertile group exhibited lower amounts of VDBP and lower levels of free and accessible vitamin D Table (2): Vitamin D Status according to 25(OH)-D Levels [36] than fertile groups, according to 2017 research.…”
