- Abstract Objective. To assess the caries risk following 6 weeks' use of 5000 ppm F toothpaste using 'Cariogram' software. Materials and methods. A total of 34 participants, 17 mothers and their teenage children, were enrolled in a 6-week clinical trial in which they were given 5000 ppm F toothpaste. They were followed consecutively for 6 weeks with visits that were 2 weeks apart (four in total). A clinical examination was done at baseline and salivary chair-side tests to record the buffer capacity and mutans streptococci (MS) and lactobacilli (LB) counts were performed at each visit. Based on these data, seven caries-related variables were collected and inserted into the Cariogram software to calculate the actual chance of avoiding caries. Results. The use of 5000 ppm F toothpaste resulted in a statistically significant modification of the caries-risk profile, increasing the actual chance of avoiding caries in the future among the mothers and teenagers at each visit following baseline (p < 0.01). The changes essentially related to the salivary parameters (buffer capacity, MS and LB counts). A statistically significant linear trend was observed for MS counts (p < 0.01) and the number of subjects with a salivary concentration of MS < 10(3) increased at each visit. The same trend was also observed for LB and buffer capacity scores (p = 0.04 and p = 0.03, respectively). Conclusions. The short-term use of 5000 ppm F toothpaste is able to reduce the caries risk, which can be clearly demonstrated using 'Cariogram' software.

- Background/purpose: Dental caries remains a major health problem in many parts of the world. The present study aimed at describing the caries experience and caries-related factors in mothers and their preschool and school children. Materials and methods: A sample of 258 individuals (86 mothers and 2 of their children, 4-6 and 12-16 years old) was included. An interview was used to determine the socioeconomic status of the family, oral hygiene, and snacking habits. DMFT /dmft (decayed, missed, filled, teeth), plaque, and gingival indices were recorded. Chair-side tests were used to register salivary buffer capacity and bacterial counts. Results: The caries experience (DMFT/dmft) was high in mothers and their younger and older children (12.4 +/- 5.3, 9.0 +/- 5.0, and 5.8 +/- 4.1, respectively). The DMFT/dmft increased with higher salivary mutans streptococci counts in all age groups (P < 0.05). The caries experiences of the children were correlated positively with those of their mothers (R-4-6(2) = 0.12, R-12-16(2) = 0.18, P < 0.01). A positive association between mothers and both children was evident for toothbrushing habits, snacking frequency, and gingival health (P < 0.05). An association between plaque scores, salivary buffer capacity, and mutans streptococci counts was found between mothers and older children (P < 0.05). Conclusion: The caries experience in Saudi mothers and their children is high, with similar contributory caries-related factors.

- OBJECTIVES: The aim of the present study was to measure the effects of a 5,000-ppmF toothpaste on caries-related factors in dental plaque and saliva. MATERIALS AND METHODS: A 6-week clinical trial was designed with a total of 34 participants, of which 26 completed the study. The participants were assessed on four visits, 2 weeks apart. Sampling of approximal fluid for fluoride analysis and approximal plaque for organic acid analysis was performed. Chair-side tests were performed to register the lactic acid production rate on the tongue using Clinpro™ Cario L-Pop™, approximal plaque pH using the pH "strip method" and salivary buffer capacity and counts of cariogenic microorganisms using CRT Buffer® and CRT Bacteria®. RESULTS: Six weeks' use of 5,000-ppm fluoridated (F) toothpaste significantly increased the approximal fluid F concentration (p<0.05). There was a significant decrease in lactic acid production rate on the tongue assessed by Clinpro™ (p<0.05). This was accompanied by changes in interproximal plaque acidogenicity, including significant reductions in AUC5.7, AUC6.2 and maximum pH fall and an increase in minimum pH (p<0.05). A significant increase in the salivary buffer capacity and a reduction in the salivary mutans streptococci were observed (p<0.05). CONCLUSION: The present study demonstrates the ability of 5,000-ppm F toothpaste to modify caries-related factors in dental plaque and saliva. CLINICAL RELEVANCE: The 5,000-ppm F toothpaste could be regarded as a possible effective regimen against caries in the near future

- ABSTRACT: BACKGROUND: Dental caries develops as a result of the metabolism of carbohydrates by cariogenic bacteria present in a complex biofilm. The present study aimed to examine if bacteria in pooled supragingival plaque samples quantified using a "checkerboard DNA-DNA hybridization" based panel of caries-related bacteria, could reflect the caries experience in a manner similar to saliva samples analysed using a chair-side method in a previous investigation. METHODS: A total of 86 mothers and their children aged 4-6 years and 12-16 years old participated. Caries experience (DMFT/dmft; Decayed, Missing and Filled Teeth for permanent and primary teeth) was registered clinically and radiographically. Caries was recorded at the D3 level (caries into dentine). The D/d component was divided into three categories. A pooled supragingival plaque sample per participant was obtained from posterior approximal sites. Analyses of 15 bacterial species were performed using the checkerboard DNA-DNA hybridisation technique. RESULTS: No significant relationships were found between the bacterial scores and DMFT/dmft nor D/d groups. CONCLUSIONS: Unlike the saliva samples and the chair-side method, interproximal pooled plaque samples analysed using the "checkerboard DNA-DNA hybridization technique" did not reveal any significant relations between the bacterial counts and the caries experience.
