  2. What is Xylitol? 1 source: medchemexpress.com ● Tooth-friendly, non-fermentable sugar alcohol ● Natural sweetener in chewing gum ● Colorless, crystalline structure ● Sweetness comparable to table sugar; less calories ● In fruit and vegetables, made by body ● Industrial production from wood source: superfoodevolution.com

  3. History of Xylitol 1 ● Greek ‘Xylo’ for wood ● Originally from birch, often called ‘birch sugar’ ● First isolated in Germany and France in the 1890’s ● Early studies conducted in Finland in the 1960’s ● Benefits researched by numerous studies source: nutritionadvance.com

  4. Oral Health Benefits of Xylitol 2,3 ● Promotes remineralization ● Reduces numbers of bacteria ● source: weldental.com Lowers plaque levels source: gettyimages.com ● Decreases caries occurrence ● Reduces xerostomia ● Lessens incidence of erosion ● Enables neutral pH ● Improves malodor

  5. How to use Xylitol effectively ? 4 ● At least 3 times a day ● After a meal/snack ● For at least 5-10 min ● In daily doses of 5-6 g ● Regularly, longterm ● In high xylitol concentrations source: confectionarynews.com

  7. Results from the Xylitol for Adult Caries Trial (X-ACT) 6 By Bader JD, Vollmer WM,and Shugars DA, et al. Type of study: RCT Objective: In this randomized placebo-controlled trial, the authors evaluated the effectiveness of xylitol lozenges in preventing caries in adults at elevated risk of developing caries. Methods: 691 participants, aged 21-80 consumed five 1 g xylitol or placebo lozenges daily for 33 months. Participants underwent clinical examinations at baseline and at 12, 24 and 33 months. Result/Conclusion: Xylitol lozenges reduced the caries increment 10 percent. This reduction, which represented less than one-third of a surface per year, was not statistically significant.

  8. Six months of high-dose xylitol in high-risk caries subjects—a 2-year randomised, clinical trial 7 Type of study: Randomised Clinical Trial , Double-blind Research Question: In high-risk school children, is use of a high dose of a xylitol gum for 6 months, comparing to non-xylitol gum, more effective in reduction of development new caries on permanent first molar, and reduction of SM & LB, after 2 years? Inclusion criteria: the presence of two or three carious lesions The presence of all the first permanent molars. Salivary SM concentration of >105 CFU/mL Exclusion Criteria : Children with systemic disease Systemic antibiotic use during the past 6 months

  9. Method/Material: 157 children with high caries risk Xylitol group: 11.6 g, five times a day immediately after main meals and snacks , for 5 min Non-xylitol group: Non-xylitol gum Caries status ● Salivary SM and Lb concentration ….. At beginning & After 2 years ● Result/Conclusion Caries status ● Xylitol group: showed a significantly lower increase in the number of new carious lesions. Salivary SM and Lb concentration ● No significant finding

  10. Linear response of mutans streptococci to increasing frequency of xylitol chewing gum use: a randomized controlled trial 8 Type of study: Randomised Clinical Trial(RCT) Double-blind Research Question: Dose using xylitol gum 3 and 4 times/day, comparing to 2 times/day, or using non-xylitol gum significantly reduce SM level in Plaque and saliva? Exclusion Criteria: Taking antibiotics during the last four weeks Subjects with history of GI problems Subjects intolerant to phenylalanine. Method & Material: Participants (n = 132) Active groups: 10.32 g xylitol/day ● 2 times/day ● 3 times/day ● 4 times/day Placebo control: Sorbitol SM in …. Plaque & Saliva Baseline & After five weeks

  11. Result & Conclusion linear response relationship between the reduction of SM and the increase in frequency of xylitol gum use. 2x/day: Smaller reduction of SM It was not statistically different from the control G 3x/day & 4x/day : Significantly difference in reduction SM relative to the control group

  12. Xylitol pediatric topical oral syrup to prevent dental caries: 9 a double blind, randomized clinical trial of efficacy By Peter Milgrom, DDS, Kiet A. Ly, MD, MPH, Ohnmar K. Tut, BDS, Lloyd Mancl, PhDa, Marilyn C. Roberts, PhD, Kennar Briand, MB,BS, and Mary Jane Gancio, MD Type of Study: Double blinded RTC Objective: To evaluate the effectiveness of a xylitol pediatric topical oral syrup to reduce the incidence of dental caries of very young children Exclusion: (1) were in the lower 10 percentile of U.S. standard weight and height, ➢ (2) had a history of esophageal or digestive disease, (3) had congenital craniofacial malformation, or (4) had a history of adenoidectomy, tympanostomy tubes, or tympanic membrane perforations.

  13. 9 Xylitol pediatric topical oral syrup to prevent dental caries: a double blind, randomized clinical trial of efficacy By Peter Milgrom, DDS, Kiet A. Ly, MD, MPH, Ohnmar K. Tut, BDS, Lloyd Mancl, PhDa, Marilyn C. Roberts, PhD, Kennar Briand, MB,BS, and Mary Jane Gancio, MD Method: 108 healthy age 9-15 months were screened and 100 were enrolled. Parents apply 8g of xylitol syrup per day in 2 active treatment conditions for 12 months 2 doses of xylitol (4g xylitol per dose) ➢ 3 doses of xylitol (2.67g xylitol per dose) ➢ Result: 94 had at least 1 follow up caries assessment and were included in the final analysis. Nearly 52% of children in control condition had tooth decay ➢ 40.6% of children among Xyl-3X and 24.2% of group Xyl-2X had tooth decay ➢ There was no significant difference between the two xylitol conditions (P=0.22) ➢ Conclusion: Oral xylitol syrup administered topically two or three times each day at a total dose of 8 g was effective in preventing Early Childhood Caries.
