Background: Adolescents are considered good cadres to be able to socialize with this healthy dental behavior. Therefore, designing a dental health education program is necessary to prepare adolescents to socialize with dental health behavior. Purpose: This study evaluates the pilot training for trainers using persuasive communication to socialize dental health behavior. Methods: Thirty-five participants (13-16 years old) are trained by a persuasive communication coach and practice the skills with a simulated client”this one-day training has a two-phase structure; lectures and practicum. The evaluation is done through three out of four-level methods from Kirkpatrick (1959). The data analysis used for the reaction evaluation is descriptive statistics, calculating the average score per category of training support assessment items (curriculum, facilitator, accommodation, and overall score). The learning outcome analysis resulted from an analysis of the pre-post test results using the N-Gain value and paired T-test. Behavior outcomes were also analyzed descriptively by calculating the average score of all participants in every timeline (baseline and two weeks after the training). Results: evaluation of this training revealed that "reaction” has an average total score was 4.02, which shows that the participants were satisfied with the training, "learning” has an N-Gain acquisition of 48.28%, and "behavior” level shows a good outcome as an increased in points from 3.4 to 4.2. Conclusion: The training program produced thirty cadres ready to implement the program in the community.

Objectives Research indicates a high prevalence of dental caries and significant unmet dental treatment needs among individuals with disabilities. This study aimed to evaluate the oral health status of disabled students in Tehran, Iran, considering factors such as age, gender, and type of disability. Methods The study involved 1,170 disabled students aged 6 to 20 years, each with one or more of the following disabilities: physical retardation (PR), hearing impairment (HI), visual impairment (VI), mental retardation (MR), and autism spectrum disorder (ASD). The mean decayed, missing, and filled teeth index was used as an oral health indicator (dmft for children aged 6- 12 years, and DMFT for children older than 9 years). Mann-Whitney and Kruskal-Wallis tests at significant level of 0.05 were conducted for comparisons. Results Mental retardation (MR) was the most prevalent disability (59.4%). The decayed component constituted the largest part of the mean dmft (82%) and DMFT (75%) indices in all age groups. Girls had significantly higher DMFT scores compared to boys (P < 0.001). Among the different disabilities, children with HI had the highest dmft score (mean ± SD = 2.17 ± 2.86), while those with MR had the highest DMFT score (mean ± SD = 3.76 ± 3.83). Additionally, the caries-free ratio was significantly higher among VI students in the 9-12 years (40.5%) and older than 13 years (38.8%) age groups. Conclusion The dmft/DMFT scores were elevated among disabled children, yet they remained lower than those of healthy children. Dental caries were more common in girls. Although children with VI had lower dmft/DMFT scores, those with HI had the highest dmft scores, and those with MR had the highest DMFT scores. [ABSTRACT FROM AUTHOR]

Background: Dental caries disease is a dynamic process with a multi-factorial etiology. It is manifested by demineralization of enamel followed by damage spreading into the tooth inner structure. Successful early diagnosis could identify caries-risk and improve dental screening, providing a baseline for evaluating personalized dental treatment and prevention strategies. Methodology: Salivary proteome of the whole unstimulated saliva (WUS) samples was assessed in caries-free and caries-susceptible individuals of older adolescent age with permanent dentition using a nano-HPLC and MALDI-TOF/TOF mass spectrometry. Results: 554 proteins in the caries-free and 695 proteins in the caries-susceptible group were identified. Assessment using bioinformatics tools and Gene Ontology (GO) term enrichment analysis revealed qualitative differences between these two proteomes. Members of the caries-susceptible group exhibited a branch of cytokine binding gene products responsible for the regulation of immune and inflammatory responses to infections. Inspection of molecular functions and biological processes of caries-susceptible saliva samples revealed significant categories predominantly related to the activity of proteolytic peptidases, and the regulation of metabolic and catabolic processes of carbohydrates. Conclusions: Proteomic analysis of the whole saliva revealed information about potential risk factors associated with the development of caries-susceptibility and provides a better understanding of tooth protection mechanisms.

Objective: To compare oral hygiene practices, education and social background, food intake and oral malodor of Algerian adults suffering from dental caries with normal controls, and to determine and compare the bacterial composition of the supragingival plaques from the above-mentioned groups. Methods: Participants completed a questionnaire and were clinically examined for dental caries using decayed, missing and filled teeth index according to the criteria laid down by the World Health Organization. Supragingival plaque samples were collected from 50 caries-free adults (CF) and 50 caries-active adults (CA). Standard procedures of culture and identification of aerobic and anaerobic bacteria were used. Data were analyzed using Chi-square test. Results: A total of 117 bacterial strains were isolated from supragingival plaques in CF group subjects, 76 (64.96%) of them belonged to 9 aerobic genera, and 41 (35.04%) to 9 anaerobic genera (P

Background and Aim: The present study was undertaken to evaluate the pH, buffering capacity, viscosity and flow rate of saliva in caries free, minimal caries and nursing caries children and to evaluate the relationship of these on the caries activity of children. Materials and Methods: A total of 75 school children of age group between 4 and 12 years were selected and divided into three equal groups: Group I, Group II and Group III, consisting of 25 subjects each. Group I included caries-free subjects, Group II included subjects with minimal caries and Group III included subjects with nursing caries. Saliva samples were collected from all subjects and were estimated for flow rate, pH, buffering capacity and viscosity. Results: There was a significant decrease in the mean salivary flow rate, salivary ph and salivary buffer capacity and a significant increase in the salivary viscosity among caries-free subjects, subjects with minimal caries and subjects with nursing caries. Conclusion: The physicochemical properties of saliva, such as salivary flow rate, pH, buffering capacity and viscosity, has a relation with caries activity in children and act as markers of caries activity.

Aim: The aim of the present study was the evaluation of non-microbial salivary caries activity parameters and salivary biochemical indicators in predicting dental caries. Materials and Methods: The present study was carried out on 60 children, aged 4-6 years, selected from the schools of Panchkula district, Haryana, on the basis of their caries status. Level of hydration, flow rate, pH, buffering capacity, relative viscosity, calcium, phosphorus and alkaline phosphatase levels in caries-free and caries-active children were evaluated. Results: Results showed that 90% of subjects in the caries-free group and 30% of subjects in the caries-active group had normal level of hydration value of less than 60 s and the difference was found to be statistically very highly significant. Normal flow rate of stimulated saliva was found in 90% of the subjects in caries-free group and 33.3% subjects in the caries active group and difference was found to be statistically very highly significant. Adequate salivary pH was found in 100% subjects in caries-free group and 30% in caries-active group and the difference was statistically very highly significant. Conclusion: To conclude, within limitations of this study, it became clear that normal level of hydration and higher values for flow rate, pH, buffering capacity of saliva lead to good oral health and a reduced caries occurrence. Increased salivary viscosity plays a role in increasing caries incidence. Salivary biochemical indicators like calcium, phosphorus and alkaline phosphatase also play their respective role in determining caries susceptibility of an individual. These salivary parameters can be used as diagnostic tool for caries risk assessment.

While in the second group, 199 strains were isolated, 119 (59.80%) of the strains belonged to 10 aerobic genera and 80 (40.20%) to 10 anaerobic bacteria (P < 0.05). Streptococcus mutans, Enterococcus faecium, Aerococcus viridans, Actinomyces meyeri, Lactobacillus acidophilus and Eubacterium limosum showed a significantly higher prevalence in the CA group (P < 0.05). The findings revealed that CA group had a high sugar intake (80%). A significantly higher frequency of tooth brushing (P < 0.000) and a significantly less self-reported oral malodor (P < 0.000) and tooth pain (P < 0.000) were found in CF group, while there was no association of socioeconomic levels and intake of meal snacks with dental caries. Conclusions: This study confirms the association of some aciduric bacteria with caries formation, and a direct association of sugar intake and cultural level with dental caries. Furthermore, oral hygiene practices minimize the prevalence of tooth decay. [ABSTRACT FROM AUTHOR]

Using data from the Center for Oral Health Research in Appalachia Study, we examined variability in susceptibility to dental caries among children and adolescents in rural Appalachia. Among 210 participants who were caries-free at the initial visit, age at the baseline visit can be used as a proxy for the degree of caries resistance; probability of caries development at the tooth level decreased as age at the baseline visit increased. Participants who stayed caries-free for a longer period during childhood and adolescence experienced less extensive caries, as measured by the number of carious teeth. However, the probability of becoming caries-positive did not correlate with age at the baseline visit. For children between 1 and 18 years of age, there was not a “threshold age” after which a caries-free child’s risk of caries onset is significantly reduced. [ABSTRACT FROM PUBLISHER]

This study aimed to investigate effects of caries activity on composition of mutans streptococci in saliva-induced biofilms formed on bracket materials. Three bracket materials were used as specimens: ceramic, metal, and plastic. After saliva was collected using a spitting method from caries-active (CA, decayed, missing, filled teeth (DMFT) score ≥ 10) and caries-free (CF, DMFT score = 0) subjects, saliva was mixed with growth media in a proportion of 1:10. The saliva solution was then incubated with each bracket material. After a saliva-induced biofilm was developed on the surface of the bracket material, the amounts of total bacteria and mutans streptococci were determined using real-time polymerase chain reaction. The results showed that biofilms from CA saliva contained more mutans streptococci but less total bacteria than biofilms from CF saliva, regardless of material type. Adhesion of total bacteria to ceramic was higher than to plastic, regardless of caries activity. Mutans streptococci adhered more to ceramic than to metal and plastic in both biofilms from CA and CF saliva, but there was a difference in adhesion between Streptococcus mutans and Streptococcus sobrinus. The amount of S. mutans was higher than that of S. sobrinus in biofilms from CA saliva despite similar amounts of the two strains in biofilms from CF saliva. The stronger adhesion of S. mutans to ceramic than to metal and plastic was more evident in biofilms from CA saliva than in biofilms from CF saliva. This study suggests that caries activity and material type significantly influenced composition of mutans streptococci in biofilms formed on bracket materials. [ABSTRACT FROM AUTHOR]
