RESUMO

Purpose: The purpose of this clinical study was to evaluate the effectiveness of a curved rubber bristle interdental cleaner, as compared to dental floss, in the reduction of gingivitis and plaque.Methods: Gingival Index (GI), Bleeding on Probing (BOP), Periodontal Probing Depth (PPD) and Modified QH Plaque Index (MQH-PI) parameters were evaluated in an examiner-masked, parallel group, controlled clinical study. A total of 50 participants with gingivitis (no site with PPD >4 mm, BOP ≥10% but ≤50%) met the eligibility criteria. Participants were randomly assigned to either the curved rubber bristle interdental cleaner (cRBIC) group or the ADA-accepted dental floss (Floss) group. Participants used the devices for four weeks. Parameters were obtained at 2 and 4 weeks. Participants scored their level of product familiarity, satisfaction and motivation for interdental cleaning.Results: There were no statistically significant differences between the two groups in changes from baseline to 2 or 4 weeks in GI, BOP%, and MQH-PI. However, cRBIC group showed greater reduction of PPD at 4 weeks from baseline, compared with Floss group (p<0.05). The cRBIC group showed overall better compliance level than Floss group. The mean score of "ease of use" of the cRBIC group was significantly greater than that of Floss group. However, Floss group showed higher levels of "satisfaction" than cRBIC group. Motivation for interdental cleaning was higher in cRBIC.Conclusion: The cRBIC was similar to Floss in clinical effectiveness; however, PPD reduction at 4 weeks was greater with the cRBIC. Ease of use of cRBIC may have affected the participants' motivation for interdental cleaning, resulting in better compliance.

RESUMO

Purpose: To describe toothbrushing frequency/duration and toothpaste use among young children in an urban, vulnerable population in Chicago, Ill., USA.
Methods: Caregivers of children younger than three years old were recruited from university and community pediatric dental clinics. Caregivers completed a 37-item questionnaire in English or Spanish about predictors/covariates (demographics, child/caregiver oral health, access to dental care) and primary outcomes (child toothbrushng behaviors, toothpaste use). Models employed generalized logit and ordinal logistic regression.
Results: A total of 148 caregivers completed the survey. The average child age was 18.8 months (±7.4 SD). Approximately 41 percent of children brushed once a day or less, and 19 percent of caregivers did not regularly assist. Almost all children used toothpaste (96 percent), but 36 percent of caregivers did not know if it contained fluoride. Increased child brushing frequency was associated with older child age, higher caregiver brushing frequency, history of a child dental visit, and caregiver assistance (P<0.05). Children with a history of dental visits were seven times more likely to brush for 30 seconds or more, and receiving caregiver assistance was associated with brushing longer than two minutes (P <0.05).
Conclusion: Most children brushed at least once daily and nearly all of them used toothpaste. Access to dental care, parental involvement, and parental oral health were associated with favorable child toothbrushing behaviors. Toothbrushing duration, frequency, and encouraging family assistance are modifiable protective factors and opportunities for intervention.

RESUMO

Many types of interdental instrument, such as dental floss and interdental brushes, can be purchased easily and sell in large numbers. Many studies have compared the effects of such instruments. Few studies have investigated their relationship with regions of residual plaque, however. The purpose of this study was to compare rates of plaque removal from the mesial and distal surfaces of the bilateral maxillary and mandibular premolars and molars among 3 types of interdental instrument: finger-winding-dental floss, holder-type dental floss, and an interdental brush. Prior to the experiment, the artificial teeth in a jaw model were removed for application of artificial plaque. The teeth were then replaced and the model attached to a phantom. An operator brushed the teeth in a posture close to that adopted in actual tooth brushing with each type of instrument, after which the plaque removal rate was compared among them. The rate of plaque removal using finger-winding floss was the highest, although this type of instrument is less easy to hold than the others. The rate with a handle-equipped interdental instrument showed a decrease in some regions, although it is easy to hold. The results of this study suggest that the type of interdental instrument used should differ depending on the region to be cleaned.

RESUMO

PURPOSE: To investigate dental enamel wear caused by erosion and abrasion while using a combination of anti-erosive toothbrush/-paste. MATERIALS AND METHODS: A total of 60 enamel specimens from bovine incisors were randomly assigned into five groups of 12 specimens each (G1-5, n = 12): (G1) control group (no treatment), (G2) standard medium toothbrush Paro M43 and standard toothpaste Elmex Caries Protection, (G3) standard medium toothbrush Paro M43 and anti-erosive toothpaste Elmex Protection Erosion, (G4) anti-erosive toothbrush Elmex Erosion Soft and standard toothpaste Elmex Caries Protection, (G5) anti-erosive toothbrush Elmex Erosion Soft and anti-erosive toothpaste Elmex Protection Erosion. Initially, surface baseline profiles were recorded using profilometry. In a total of 60 cycles, all specimens were exposed to hydrochloric acid (pH = 3) for 1 min, rinsed with tap water to stop the erosive attack and brushed according to the specific protocol of each group (15 brushing strokes per run). Enamel loss was determined by comparing the surface profiles before and after 60 cycles and the results were statistically analysed using analysis of variance (ANOVA). RESULTS: The significantly highest loss of enamel was observed in the control group G1(1.4 ± 0.20 µm) (p < 0.001). G2 turned out to be the most abrasive toothbrush/-paste combination (1.12 ± 0.15 µm), G3 the least invasive (0.40 ± 0.04 µm) (p < 0.001, respectively). CONCLUSION: All combinations of the investigated toothbrushes/-pastes reduce erosive/abrasive enamel wear. However, the highest reduction was observed for the combination of anti-erosive toothpaste and standard toothbrush (G3).

RESUMO

OBJECTIVE: To investigate the status of oral health knowledge, attitude, behavior of 12-15 years old children and provide a theoretical basis of prevention. METHODS: Multi-stage stratified sampling method was used to extract four middle school students from Chongqing districts and counties (2 in the main urban area and 2 suburbs), and their oral health knowledge, attitudes and behaviors were investigated through questionnaires. All data were entered using Epidata and statistical analysis was performed using SPSS 21.0 software. RESULTS: A total of 3 902 valid questionnaires were collected. The proportion of people who had good brushing habits was 39.7% (1 548), the average oral health knowledge accuracy rate was 58.9%, and the average oral health positive attitude was 88.6%. The number of middle school students who attended the dental experience was 54.5% (2 127), and that of the school who received oral health education was 17.5% (681). There were gender and regional differences in brushing habits. CONCLUSIONS: The knowledge and behavior of oral health among 12-15-year-old middle school students in Chongqing need to be improved. Oral health education for middle school students should be strengthened, especially in rural and suburban areas.

RESUMO

OBJECTIVE: The aim of this cross-sectional study was to evaluate the association between tobacco use and dental fear when adjusting for gender, parent's level of education and oral health habits. MATERIAL AND METHODS: This secondary analysis used questionnaire data from 15- and 16-year-old adolescents and their parents (n=2486). Ninety-four percent of the adolescents and 73% of the parents responded. For logistic regression analysis, variables were categorized as follows: dental fear (dependent) 0=not at all to somewhat afraid, 1=quite or very afraid; tobacco use (independent) 0=never, 1=occasionally or more often; and for confounders: tooth-brushing 0=at least twice a day, 1=once a day or less often; xylitol products 0=at least three times a day, 1=two times a day or less often; and parents' occupation: 0=both low, 1=high+low, and 2=both high. RESULTS: 2223 adolescents were included in the final analyses resulting in a 89% response rate. Those using tobacco at least occasionally were more likely to have dental fear than those who reported they had never used tobacco, also when adjusting for oral health habits, gender and parents' occupation (OR=1.74, 95% CI=1.31-2.33). CONCLUSIONS: Adolescent tobacco users were more likely to have dental fear than non-users. Dental teams should consider this when meeting adolescents who have dental fear and/or are using tobacco. The possible common vulnerability factors for dental fear and tobacco use needs further study.

RESUMO

PURPOSE: To compare the effects of oscillating-rotating (O-R), sonic (side-to-side), and manual toothbrushes on plaque and gingival health after multiple uses in studies up to 3 months. METHODS: A meta-analysis was conducted on randomized clinical trials (RCTs) up to 3 months in duration to evaluate O-R electric toothbrush effectiveness regarding gingivitis reduction and plaque removal versus sonic and/or manual toothbrushes. To ensure access to subject-level data, this meta-analysis was limited to RCTs involving O-R toothbrushes from a single manufacturer conducted from 2007 to 2017 for which subject-level data were available and that satisfied criteria of duration, parallel design, examiner-graded, etc. For gingivitis studies, a one-step individual subject meta-analysis was used to assess direct and indirect treatment differences and to identify any subject-level covariates modifying treatment effects. In the two-step meta-analysis, individual participant data were first analyzed in each study independently using the last timepoint (up to 3 months), producing aggregate data for each study. Then forest plots were produced using these aggregate data with random-effects models. For plaque studies, the efficacy variables were standardized so direct comparisons could be generated using the 2-step meta-analysis. Network meta-analysis was performed to assess the indirect plaque comparisons. RESULTS: 16 parallel group RCTs with 2,145 subjects were identified assessing gingivitis via number of bleeding sites. In five and 11 gingivitis studies assessing O-R brushes versus manual and sonic brushes, respectively, a change in the average number of bleeding sites of -8.9 ( 95% CI: -15.9, -1.9) and -3.1 (95% CI: -3.8, -2.4) was observed (P ≤ 0.008). These reductions equate to a 50% and 28% bleeding benefit for O-R technology versus the respective controls. The sonic brush bleeding change versus manual was -5.9 (P = 0.062), a 34% bleeding benefit. Utilizing individual bleeding scores, subjects with localized or generalized gingivitis (≥ 10% bleeding sites) had 7.4 times better odds of transitioning to generally healthy (< 10% bleeding sites) after using an O-R brush versus manual. 20 parallel design RCTs with 2,551 subjects assessed plaque (TMQHI, RMNPI). In eight and 12 plaque RCTs assessing an O-R brush versus manual and sonic brushes, respectively, standardized changes in average plaque scores of -1.51 (95% CI: -2.17, -0.85) and -0.55 (95% CI: -0.82, -0.28) were observed (P< 0.001). These plaque reductions by O-R equate to a relative 20% and 4% greater benefit, respectively. The change for sonic versus manual was -0.93 ( 95% CI:-1.48, -0.38); (P < 0.001) which equates to a 12% plaque benefit. CLINICAL SIGNIFICANCE: This subject-level meta-analysis of studies up to 3 months provides sound evidence supporting recommendations for patients with various degrees of gingival bleeding to use oscillating-rotating electric toothbrushes over manual and sonic toothbrushes to improve plaque control and gingival health.

RESUMO

PURPOSE: To evaluate the effect of different electrical brushing systems on the surface roughness and wear profile of the enamel of sound primary teeth and teeth with induced white spot lesions. METHODS: 45 specimens were obtained from sound primary incisors, and the buccal surface was divided into four parts: sound enamel; enamel with white spot lesions; sound enamel with brushing; and enamel with white spot lesions and brushing. Specimens were randomly divided into three groups (n =15), according to the different brushing systems: Group 1 - Electric rotating toothbrush (Kid's Power Toothbrush - Oral B); Group 2 - Sonic electric toothbrush (Baby Sonic Toothbrush); and Group 3 - Manual toothbrush (Curaprox infantil) (control). The specimens were analyzed for surface roughness and wear profile. Data were analyzed by appropriate statistical tests, with a significance level of 5%. RESULTS: Regarding the surface roughness, no significant difference was observed between the groups. However, with respect to the wear profile, Group 1 caused significantly higher wear in the sound tooth enamel and in the presence of white spot lesions, in comparison to the other brushing systems (2 and 3) (P< 0.05), which did not cause wear. Manual and electric brushing (rotational and sonic) did not increase surface roughness in primary tooth enamel. However, the electric rotational brushing caused significant wear of the sound and demineralized enamel surface of primary teeth. CLINICAL SIGNIFICANCE: None of the toothbrushing systems tested caused significant alterations on sound dental enamel. However, rotational toothbrushing on enamel of primary teeth with white spot lesion increased wear.

RESUMO

This study compared the use of an oscillating-rotating powered toothbrush and a water flosser to the use of an oscillating-rotating powered toothbrush on the reduction of clinical signs of inflammation and plaque. METHODS: Seventy adult participants (N = 70) completed this examiner-blind, two-group, parallel clinical trial. The participants were randomized into either the water flosser + oscillating-rotating powered toothbrush (WF) group or the oscillating-rotating powered toothbrush only group (OR). Inflammation was measured by bleeding on probing (BOP) and modified gingival index (MGI) at baseline, 2 weeks, and 4 weeks. Plaque was scored using Rustogi Modification of the Navy Plaque Index (RMNPI) at the same timepoints. Data was reported for whole mouth, areas (marginal and proximal), and surfaces (facial and lingual). A post-study Likert scale questionnaire was completed at the 4-week visit. RESULTS: Both groups demonstrated significant reductions in BOP, MGI, and RMNPI from baseline to 4 weeks for whole mouth (P < .001). The WF group was 37% more effective at reducing BOP, 36% for MGI, and 33% for RMNPI than the OR group at 4 weeks for whole mouth (P < .001; except RMNPI P = .003). Additionally, the WF group was significantly more effective at reducing proximal BOP (37%, P < .001), MGI (46%, P < .001), and RMNPI (52%, P = .004) compared to OR at 4 weeks. The questionnaire revealed subjects in both groups felt the device was easy to use, the instructions were clear, and their mouth felt fresh and clean. There were no adverse events reported during the study. CONCLUSION: An oral hygiene regimen consisting of the use of a water flosser in addition to an oscillating-rotating powered toothbrush significantly improved gingival health. The products used in both groups were effective and well-tolerated by the study population.

RESUMO

AIM: To evaluate the impact of an oral health program for institutionalized individuals with cerebral palsy (CP) and their caregivers, after 2 and 6 months. METHODS: Sixty-two CP individuals in four homes were selected for intervention group (n = 31) and control group (n = 31). An oral hygiene practices questionnaire was applied to all caregivers at the baseline. Both groups received awareness sessions, practical demonstration of toothbrushing and adaptive techniques with role-play. In the study group, individual oral hygiene monitoring was also performed in the first 2 months. A gingival and an oral hygiene indexes were performed at the beginning, after 2 and 6 months of intervention. RESULTS: There was a significant reduction of gingival (p < 0.001) and oral hygiene (p < 0.001) indexes at 2 and 6 months in the intervention group with the most significant reductions at 2 months. Caregivers reported opening the mouth (84.6%) and swallowing toothpaste (61.5%) as the most important difficulties in performing toothbrushing. CONCLUSION: It was found that frequent and individualized monitoring of plaque control was essential to reduce dental plaque and gingivitis levels and that awareness sessions were not enough to produce clinically significant result.

RESUMO

OBJECTIVES: While common in the elderly, dry mouth can negatively affect their oral health and nutritional status. Self-administered oral care by the elderly can improve their oral health and prevent oral diseases. This study aimed to identify the content of oral health promotion programmes for community-dwelling elderly and to determine which programmes are effective in improving oral health decreasing xerostomia in these populations. METHODS: A systematic literature search and meta-analysis was conducted using the PRISMA guidelines. All available papers published in English or Korean were searched between 1 June and 13 June 2018. The relevant databases in PubMed Central, MEDLINE, CINAHL, the Cochrane Library and Embase, as well as open dissertation and academic searches, were performed. Data were extracted from the selected studies based on PICOS, and the health outcomes of the elderly were subjected to meta-analysis categorized by salivary secretion rates and oral health-related quality of life (OHQoL). RESULTS: A total of nine studies had sufficient data for a systematic review and meta-analysis. The intervention programmes consisted mainly of oral health promotion programmes, mouth exercises, toothbrushing and salivary massage. The meta-analysis indicated that elderly participating in oral health programmes had significantly increased oral salivary secretion rates and OHQoL (effect sizes of 0.63 and 0.80, respectively). CONCLUSIONS: Oral health promotion programmes in the elderly provide the positive effects of relieving dry mouth and improving OHQoL. This systematic review confirmed the contents and effects of the oral health promotion programmes provided to community-dwelling elderly.

RESUMO

BACKGROUND: Oral disease is one of the most prevalent chronic health conditions affecting children. Twice-daily toothbrushing is recommended to promote good oral health; however, a large proportion of Australian families are not meeting this recommendation. AIM: This study aimed to identify important barriers to regular toothbrushing for young children. DESIGN: In this study, 239 parents of 0- to 4-year-old children completed an online survey that investigated child, family, and parent factors associated with child toothbrushing. Hierarchical linear regression was used to identify predictors of toothbrushing frequency in children and perceived difficulty of the task by parents. RESULTS: We found that parent factors, specifically oral health knowledge, were the most significant predictors of toothbrushing frequency. Conversely, parent factors did not contribute significantly to the prediction of perceived difficulty of toothbrushing once family and child factors were taken into account. Oral health knowledge and use of routines were identified as the most important predictors of toothbrushing frequency, whereas resistant child behaviour and household organisation were found to be the most important predictors of perceived difficulty of regular toothbrushing. CONCLUSIONS: The findings of the study have implications for behavioural interventions to support parents, as well as directions for future research.

RESUMO

PURPOSE: To study the relationship between the tooth-brushing habits during the preschool ages and caries prevalence at the age of 5 years and to investigate a possible association with the mode of delivery. METHODS: The study population consisted of 336 children that were orally examined at 2, 3 and 5 years. All stages of caries were scored on tooth and surface level. Data on tooth brushing behaviour were collected through semi-structured interviews. RESULTS: At 5 years, the attrition rate was 13.1%. The total caries prevalence (cavitated and non-cavitated lesions) was 18.9%. The vast majority of the parents assisted their child with the brushing and 98% used fluoride toothpaste. The relative risk (RR) for caries was significantly (p < 0.05) increased for "tooth brushing less than twice daily" at two (RR 2.1, 95% CI 1.3-3.3, p < 0.01) and 3 years (RR 3.6, 95% CI 2.0-6.7; p < 0.001). Likewise, reporting "major/minor difficulties to perform tooth brushing" at 2 and 3 years was significantly related to caries development at the age of five (RR 1.5, 95% CI 1.0-2.4, p < 0.05 and RR 2.5, 95% CI 1.4-4.3; p < 0.01). We found no significant association between the tooth brushing habits and the mode of delivery. CONCLUSIONS: Less than twice daily tooth-brushing and difficulties to perform the procedure during the first preschool years were significant determinants of caries prevalence at the age of 5 years. Health professionals should, therefore, give special attention and assist parents to improve and optimize their tooth brushing behaviour during the preschool years.

RESUMO

INTRODUCTION: Smartphone mobile app is an innovative concept for health behaviour-based interventions. AIM: The present study aimed to analyse apps developed for smartphones that promote tooth brushing amongst children using the Coventry, Aberdeen, and London-Refined (CALO-RE) taxonomy for behaviour change. MATERIALS AND METHODS: Tooth brushing apps available in English and free to download that purported to assist with brushing were searched on the Apple app store using search terms based on Boolean logic and included AND combinations for keywords tooth brushing, children, toothbrush and motivation in the health and fitness category; six apps met the inclusion criteria and were downloaded. The behaviour change taxonomies were assessed individually for each app and scored as per coding and analysed for presence or absence. RESULTS: Only three of the behaviour change taxonomies were present in all apps, i.e. information provision (general), goal setting (behaviour) and prompt practice. Setting graded tasks, self-monitoring of behavioural outcome, demonstration of behaviour, prompt use of imagery and time management were included in four out of six apps. CONCLUSION: The present study explores a new arena for oral healthcare motivation and prevention in children through the use of mobile phone apps.

RESUMO

STATEMENT OF PROBLEM: No information is available on roughness and stainability of acrylic resins polymerized by experimental microwave cycles after immersion in stainable liquids and simulated brushing. PURPOSE: The purpose of this in vitro study was to evaluate the effect of stainable drinks and brushing on roughness and stainability of acrylic resins (Vipi Cril [CA] and Vipi Wave [MA]) polymerized with different cycles. MATERIAL AND METHODS: CA and MA specimens (n=5; diameter, 20 mm; thickness, 3 mm) were made using 4 methods recommended by the manufacturer (water bath polymerization and microwave polymerization cycles) and experimental at 550 W or 650 W for 3 or 5 minutes (M550/3 and M650/5), respectively. After storage in distilled water at 37°C for 48 hours (T0), the specimens were stored in water, coffee, or red wine (37°C) for 36 days with simulated brushing (54 000 cycles, T1). Roughness (Ra) and stainability (ΔE/National Bureau of Standards) were measured at T0 and T1. Roughness and stainability data were analyzed by 3-way repeated measures and 2-way ANOVA, respectively, followed by the Bonferroni test (α=.05). RESULTS: After storing in coffee and brushing, CA showed the highest (M550/3=2.33 ±0.72 µm) and the lowest roughness (water bath polymerization=1.22 ±0.58 µm), whereas roughness of MA specimens processed by M650/5 increased (1.57 ±0.59 µm). Storing in wine and brushing increased roughness (1.75 ±0.32 µm) in the M550/3 group. No staining was observed on MA after brushing regardless of the polymerization cycle. All values were acceptable (ΔE≤3.3), except for MA (microwave polymerization), which showed National Bureau of Standards=4.49 (appreciable change) after storing in wine and brushing. CONCLUSIONS: A slight increase in material roughness was observed after staining and brushing. Only MA polymerized following manufacturer cycles showed relevant stainability after immersion in wine and brushing.

RESUMO

OBJECTIVES: In adult participants, what is, following a single brushing exercise, the efficacy of a powered toothbrush (PTB) as compared to a manual toothbrush (MTB) on plaque removal? METHODS: MEDLINE-PubMed and Cochrane-CENTRAL were searched from inception to February 2019. The inclusion criteria were (randomized) controlled clinical trials conducted in human subjects ≥18 years of age, in good general health and without periodontitis, orthodontic treatment, implants and/or removable prosthesis. Papers evaluating a PTB compared with a MTB in a single brushing exercise were included. When plaque scores were assessed according to the Quigley-Hein plaque index (Q&HPI) or the Rustogi modified Navy plaque index (RMNPI). From the eligible studies, data were extracted. A meta-analysis and subanalysis for brands and mode of action being oscillating-rotating (OR) and side-to-side (SS) were performed when feasible. RESULTS: Independent screening of 3450 unique papers resulted in 17 eligible publications presenting 36 comparisons. In total, 28 comparisons assessed toothbrushing efficacy according to the Q&HPI and eight comparisons used the RMNPI. Results showed a significant effect in favour of the PTB. The difference of Means (DiffM) was -0.14 (P < 0.001; 95%CI [-0.19; -0.09]) for the Q&HPI and -0.10 (P < 0.001; 95%CI [-0.14; -0.06]) for the RMNPI, respectively. The subanalysis on the OR mode of action showed a DiffM -0.16 (P < 0.001; 95%CI [-0.22, -0.10]) for the Q&HPI. For the SS mode of action using RMNPI, the DiffM showed -0.10 (P < 0.001; 95%CI [-0.15; -0.05]). The subanalysis for brands showed for the P&G OR PTB using the Q&HPI a DiffM of -0.15 (P < 0.001; 95%CI [-0.22; -0.08]) and the Colgate SS for RMNPI showed a DiffM of -0.15 (P < 0.001; 95%CI [-0.18; -0.12]). CONCLUSION: There is moderate certainty that the PTB was more effective than the MTB with respect to plaque removal following a single brushing exercise independent of the plaque index scale that was used.

OBJECTIVE: This in vitro study aimed to evaluate different periods of exposure to clarified human saliva for the ability to protect enamel against erosive tooth wear. METHODS: For this purpose, sixty specimens (4 × 4 × 1.5 mm) were prepared from third human molars. For all groups, the period before abrasion was performed by remineralisation with human saliva (except in G1). The specimens were randomly divided into six groups (n = 10) according to the different remineralisation times of exposure to clarified human saliva: no exposure to saliva (G1) and 30 min (G2), 60 min (G3), 90 min (G4), 120 min (G5), and 240 min (G6) of exposure to human saliva. A 5-day cycling was performed with 5 min of erosion (1% citric acid; pH 2.3), 4x/day. After the first and last erosive episodes, the abrasion challenge was performed with slurry of fluoride toothpaste (1450 ppm F-, as sodium monofluorophosphate) plus human saliva (1:3), with an electric toothbrush (15 s, with a total of 120 s of slurry immersion). Surface loss (SL) was determined using an optical profilometer (n = 10) and for qualitative analysis, environmental scanning electron microscopy (ESEM) was performed (n = 3). The SL data were statistically analysed by one-way analysis of variance (α = 0.05). RESULTS: No significant differences were detected among the groups for SL (p > 0.05), and ESEM showed similar aspects of eroded enamel. CONCLUSIONS: The period of in vitro exposure to clarified human saliva was not able to protect against enamel erosion.

RESUMO

OBJECTIVES: This study evaluated the erosive tooth wear promoted by commercial whitening toothpastes on eroded dentin in vitro. DESIGN: Ninety bovine roots were embedded, polished and subjected to the baseline profile analysis. The samples were protected in 2/3 of the dentin surface and were randomly assigned to 6 groups (n = 15/group): Oral-B 3D White; Close-up Diamond Attraction Power White; Sorriso Xtreme White 4D; Colgate Luminous White; Crest and erosion only. All samples were submitted to erosive pH cycles (4 × 90 s in 0.1% citric acid, pH 2.5, per day) and abrasive challenges (2 × 15 s, per day) for 7 days. The samples were subjected to abrasion, using toothbrushing machine, soft toothbrushes and slurries of the tested toothpastes (1.5 N, 1:3 water). Between the challenges, the samples were immersed in artificial saliva. The final profile was overlaid to the baseline profile for the calculation of the erosive dentin wear (µm). The data were subjected to Kruskal-Wallis/Dunn tests (p < 0.05). RESULTS: Colgate Luminous White (4.7 µm) and Sorriso Xtreme White 4D (4.0 µm) promoted the highest wear, similarly to Oral-B 3D White (2.3 µm). Oral-B 3D White promoted similar wear compared to Crest (1.1 µm) and Close-up Diamond Attraction Power White (1.2 µm); however, it induced significant higher dentin wear compared to erosion only (1.0 µm). Close-up Diamond Attraction Power White and Crest did not increase the erosive wear compared to erosion only. CONCLUSION: Some whitening toothpastes increase the wear of eroded dentin, which should be considered by the dentist when prescribing them to patient with root exposure.

RESUMO

PURPOSE: To study changes of children caries activity after treatment under general anesthesia, and to analyze effect of caries treatment under general anesthesia on oral health behavior and growth index of children. METHODS: Patients who met criteria and were treated under general anesthesia were included in this study. Informed consent for this study was obtained from parents. Before and after treatment, children's oral health conditions were examined; height, weight were recorded; the caries activity was evaluated. In addition, questionnaires related to oral health behavior and early childhood oral health impact scales were fulfilled by parents. The patients were followed for 6 months after treatment. The data were analyzed using SPSS 25.0 software package. RESULTS: The average dmft of children before treatment was 14.02. Patients with supplemental feeding during sleep and additional bottle feeding in the first 6 months had higher dmft. The incidence of caries relapse was 25.67% after 3 months and 50% after 6 months. Caries activity decreased dramatically after treatment. Among three follow-up results, Cariostat scores at the 3rd month were the lowest. After general anesthesia, the eating frequency and sweets intake decreased obviously, and the time for tooth-brushing was longer, while the children's mealtime was significantly shorter. The number of children in normal BMI range significantly increased after dental general anesthesia. CONCLUSIONS: Dental general anesthesia can reduce caries activity and improve oral health behavior, nutritional status, physical and mental health of children in a short term. However, a large number of patients were still at a high risk of caries relapse after treatment.

RESUMO

PURPOSE: To compare students' knowledge, attitudes towards oral health, and plaque scores after oral health education sessions delivered by trained schoolteachers vs the control group. MATERIALS AND METHODS: The participants, comprising third-grade students in Amphoe Meuang, Nakhonphanom province (N = 435), were randomly divided into an experimental group (n = 216) and a control group (n = 219). Baseline data of the students' oral health knowledge, attitudes, and plaque scores were collected at the beginning of the study. The experimental group was given oral health education sessions by trained schoolteachers using a specifically designed student handbook, while the control group did not receive extra oral health education other than the national curriculum. The immediate post-test knowledge was evaluated after each session, and plaque scores were determined after the brushing session. After the oral health education programme ended, the experimental and control groups performed a monthly toothbrushing activity for 2 months. Final assessment of the students' knowledge, attitudes, and plaque score was done at the 3-month follow-up. RESULTS: The experimental group's oral health knowledge statistically significantly improved immediately after each session and was still statistically significant during the following three months. This improvement was also statistically significantly higher compared with the control group. The attitudes towards oral health care, foods related to caries, and dental visit improved. The plaque score of the experimental group was statistically significantly lower immediately post-brushing, but was not statistically significantly different at the 3-month follow-up compared with baseline. CONCLUSION: The children receiving oral health education provided by trained schoolteachers had statistically significantly greater oral health knowledge and more positive attitudes towards oral health than the children who had not received the programme. No statistically significant differences in plaque scores were found after 3 months.
