Is plaque removal efficacy of toothbrush related to bristle flaring? A 3-month prospective parallel experimental study.

BACKGROUND: Toothbrushes are over-the-counter products; therefore, no special instruction is given to users when they purchase. There are scarce published studies that have investigated about how often toothbrushes should be replaced. Thus, this study aimed to verify the impact of the Progressive Toothbrush Bristle Flaring on plaque control efficacy of toothbrush. MATERIALS AND METHODS: Thirty six subjects were randomly selected and underwent complete oral prophylaxis 10 days prior to the Baseline plaque recording. All subjects were provided with new similar toothbrushes and were divided into two groups. New Brush Group changed toothbrush every month and Old month Group used single toothbrush for the whole period of the study. Both groups were assessed for plaque accumulation every month using Turesky et al, (1970) modification of the Quigley and Hein (1962) plaque index. Toothbrush head was photographed and assessed by measuring the brushing surface area on standardized photographs using National Institutes of Health Image Analysis Program (USA). RESULTS: Both groups showed similar plaque scores at the 40(th) day; progressive increase in the plaque scores in group without changing the toothbrush were recorded at the 70(th) and 100(th) days. As toothbrush flaring increased, the plaque scores also increased in the Old Brush Group. Highest plaque accumulation was recorded in Mandibular Lingual aspects in Old Brush Group. CONCLUSION: Progressive increase was seen in the plaque scores with increase in toothbrush bristle flaring.

Feeding habits and oral hygiene practices as determinants of early childhood caries in 3- to 5-year-old children of Belgaum City, India.

PURPOSE: To investigate whether feeding and oral hygiene practices of preschool children are associated with the risk and prevalence of Early Childhood Caries (EC). MATERIALS AND METHODS: A cross-sectional study comprising 1250 children aged 3 to 5 years from Belgaum was designed. On the first day, validated questionnaires along with parental informed consent forms were distributed to the children and were collected after a week. Validated questionnaires consisted of 20 close-ended questions pertaining to feeding and oral hygiene practices. Consent was obtained from parents of the 1116 children who were examined for EC. Data analysis included correlation coefficients and logistic regressions. RESULTS: Among the children studied, 97.3% were breastfed, of which 41.25% were breastfed until 2 years of age. Seventy- five percent of children who were breastfed beyond 2 years were affected by EC. Exclusive bottle feeding was practiced in 46.15%; 64.85% of them suffered from EC. Burping was not practiced in 25.18%, and 68.68% of these were affected by EC. EC was more prevalent in 89% of children who were weaned later than 12 months of age. Parental assistance for oral hygiene was not seen in 37.27% and 67.22% of these suffered from EC. Overall, 63.17% of the children were affected by EC. CONCLUSION: Prolonged breastfeeding, absence of burping the child, delay in starting oral hygiene practices and lack of parental assistance with the same were shown to be significant determining factors for EC. Health education and proper guidelines on feeding and oral hygiene practices can substantially reduce the risk and prevalence of EC.

Anti-gingivitis effects of Acacia arabica-containing toothpaste.

OBJECTIVE: To evaluate the anti-plaque and anti-gingivitis properties of Acacia arabicacontaining toothpaste in an adult population. METHODS: Sixty subjects with gingivitis were randomly assigned to a test group (Acacia arabica-containing toothpaste) or control group (regular toothpaste). An analysis of plaque index (PI), gingival index (GI) and bleeding on probing index (BOP%) were carried out at baseline and after 28 days followed by a washout period. After the washout period, the test and control groups were crossed over and the assessments were repeated. RESULTS: Reductions in PI, GI and BOP% were observed in the test group compared with the control group. CONCLUSION: Brushing with Acacia arabica-containing toothpaste may help inhibit gingivitis. It can be recommended for daily oral hygiene procedures.

Assessment of Stress Level among Dental School Students: An Indian Outlook.

BACKGROUND: Evaluating the factors influence student perception, might allow programmatic changes designed to enhance students' psychosocial well-being and academic performance. The purpose of this study was to investigate perceived sources of stress on dental students and the role of parents in their career choice decisions. METHODS: In a cross-sectional design, a modified dental environmental stress questionnaire was administered to all dental students. The responses to the questionnaire were based on a four-point Lickert scale, not stressful to severely stressful. Means and standard deviations were determined for stress scores of individuals for each item and were used to compare the classes, genders, and choices. Student's t, one way ANOVA, and Newman Keuls multiple comparison post hoc tests were used to analysed the data at the significant level of P ≤ 0.05. RESULTS: A total of 304 undergraduate students constituted the study population. Of the respondent, 60% were men and 40% were women. The final year students presented with higher stress scores. In gender comparison, men suffered more stress (62.9%) than women (60.1%). According to the career choice decision, students forced by parents had more perception of stress (69.0%) and the students staying in the hostel (62.7%) showed more perception of stress than day scholars (56.3%). CONCLUSION: The study indicates that the congenial environment needs to be created for dental education and the parents also need to be counselled against forcing their children to join an educational programme i.e. not of their choice.

Antimicrobial efficacy of various disinfecting solutions in reducing the contamination of the toothbrush -- a comparative study.

BACKGROUND: Contaminated toothbrushes may play a role in the transmission of local or systemic diseases. As modern dentistry emphasises prevention and infection control, toothbrushes should be correctly stored, disinfected and changed at regular intervals. PURPOSE: The aim of this study was to test the efficacy of 3% neem, 2% triclosan, 0.2% chlorhexidine gluconate and 1% sodium hypochlorite as toothbrush disinfectants against Streptococcus mutans. MATERIALS AND METHODS: This was a double-blind, linear crossover, within-group comparative experimental trial conducted among 40 children aged 12 to 15 years. The study was divided into five phases: (1) distilled water (control); (2) 3% neem; (3) 2% triclosan; (4) 0.2% chlorhexidine gluconate; and (5) 1% sodium hypochlorite. The toothbrushes were collected after 5 days of brushing and were soaked for 12 h in antimicrobial solutions of separate phases, after which the toothbrushes were submitted for microbial analysis to check for the presence of S. mutans. RESULTS: The mean colony-forming units (CFUs) of S. mutans at phase 1 when compared with baseline was not significant (P = 0.17). The other phases had a significant drop in mean CFUs of S. mutans from baseline (P < 0.001). The percentage reduction of mean CFUs of S. mutans from baseline was the highest in phase 2 (86%). CONCLUSION: It can be concluded that all the solutions are effective in toothbrush decontamination, but 3% neem has greater efficacy than other solutions.

The effect of different methods of drinking a carbonated beverage on the pH of dental plaque: an in vivo study.

PURPOSE: Fizzy drinks are known to be erosive or cariogenic, but little is known about the ways of reducing their harmfulness by altering the method of drinking. The purpose of this study was to assess the changes in plaque pH, at different time intervals in vivo after consuming a carbonated beverage (sprite, pH = 2.98) with plastic glass, straw and directly from bottle. DESIGN: A clinical study. MATERIAL AND METHODS: Eighteen subjects aged 18-25 years were recruited for the study and were divided randomly into three groups, six in each (group A- plastic glass, B- straw and C- directly from bottle) after the salivary pH was measured. Subjects were requested to refrain from brushing for 24 hours prior to the study. Collection of pooled plaque was done before and after consuming the drink at five, 10-, 20- and 30-minute intervals. Plaque pH was assessed by glass combination electrode. ANOVA and post hoc Tukey's test was used for statistical analysis. RESULTS: Highest mean pH drop (5.29) was recorded when consumed with plastic glass at all time intervals. There was a significant difference between group A and B at 5 min and 10 min (P < 0.05). However, no difference was seen between group B and C, A and C (P > 0.05). CONCLUSIONS: The use of a straw and direct consumption of beverage from the bottle could limit harmful effects on dentition.
