RESUMEN

The aim of this study was to determine the clinical efficacy of a dental chew with mechanical and chemical properties in 2 toy dog breeds. Eight Yorkshire terriers and 9 Chihuahuas participated in a crossover design trial. Gingivitis, dental plaque, calculus, and volatile sulfur compounds (VSC) in the breath were assessed after 4 weeks and 9 weeks, respectively. When dogs were fed 1 dental chew per day they had significantly reduced gingivitis (-20%, P < .001), accumulation of plaque (-15%, P < .001), calculus (-35%, P = .001), and VSC concentration (-19%, P < .001) compared to when receiving no chew. A significant breed effect was observed on all the average dental indices and VSC concentration.

RESUMEN

PURPOSE: Preventive dentistry aims to improve oral hygiene, including the use of interdental cleansing aids. Clear and simple classifications may positively impact patient communication and motivate oral health behaviour. To date, there is no comparative analysis of interdental brush classifications and sizes. MATERIALS AND METHODS: A total of 2320 interdental brush samples by 24 manufacturers was examined regarding their passage hole diameter (PHD) according to the ISO standard for interdental brushes (ISO16409:2016), and their current classifications were evaluated. Inter- and intrarater reliability of the ISO size classification were determined based on 20 raters and 10 interdental brushes. The insertion force for these interdental brushes was analysed in vitro. RESULTS: Excellent intra- and interrater reliability was achieved (intraclass correlation coefficient (ICC) ≥ 0.973) overall, although greater variance was observed for bigger brush sizes. Insertion forces varied depending on size and form of the brushes, amounting to 1.58 N (SD = 1.27 N) for cylindric and tapered brushes, and to 2.31 N (SD = 0.81 N) for waist-shaped brushes. The size range of commercially available products was 0.6-5.2 mm PHD, 90% presenting with a PHD ≤ 2.0 mm. Size intervals were unsystematic. The ISO size was indicated by 33% of all manufacturers, the exact PHD by 25%. CONCLUSIONS: The determination of the PHD is a reproducible instrument for most brushes currently on the market. In vitro, forces developed based on this classification are mostly moderate, thus unlikely to cause periodontal trauma. Given the discontinuous range and unclear labelling of available products, the development of a simplified classification system by usage of the PHD may benefit the practitioner and patient alike by contributing to improve oral hygiene behaviours.

RESUMEN

PURPOSE: To study the dental caries experience among adolescent school children in Chennai city using the ICDAS-II scoring system. The secondary objective was to identify associated risk factors to different thresholds of dental caries defined by ICDAS. MATERIAL AND METHODS: Two hundred and thirty-seven children (13-17 years) from five schools across Chennai city were included using simple random sampling. After obtaining assent to participate in the study and satisfying the selection criteria, 200 children were screened for dental caries using ICDAS-II. The population was assessed for the following risk factors: sociodemographic status, habits, diet, plaque and salivary parameters. Prevalence of dental caries was estimated at the following thresholds: normal (ICDAS-0/1), mild caries (ICDAS-2), moderate caries (ICDAS-3/4) and extensive caries (ICDAS-5/6). Backward logistic regression analysis was performed to identify risk factors at different thresholds and crude odds ratio was calculated for statistically significant risk factors. RESULTS: The overall prevalence of dental caries (ICDAS 3-6) was 57.5% (95% CI 48-62%). The proportions of children at different caries thresholds were: ICDAS-2 - 55% (95% CI:48-62%), ICDAS-3/4 - 51% (95% CI:44-58%) and ICDAS-5/6 - 25% (95% CI:19-31%). Reduced pH was statistically significant for moderate and extensive caries (OR 6.24, 95% CI 1.18-32.78 and 1.73, 95% CI 1.18-1.92, respectively) and the quantity of saliva was statistically significant for mild and moderate caries (OR 4.48, 95% CI 2.94-8.23 and 3.97, 95% CI 2.65-7.03, respectively). Low buffering capacity was associated with mild caries OR 5.71, 95% CI 2.82-18.2). Interobserver correlation was 0.91. A non-statistically significant value using Hosmer-Lemeshow Goodness of Fit test indicated that all three models predict the true estimate of the population. CONCLUSION: The proportions of children with mild and moderate caries were high considering their age group. The risk factors associated with mild caries were different from those associated with moderate and extensive caries.

RESUMEN

AIM: The review is to highlight the use of antibiotics in periodontal infections and prevent indiscriminate use of antibiotics. BACKGROUND: Periodontitis is the most common disease of the periodontal attachment apparatus, and its etiological factor can be related to the existence of virulent microorganisms in the dental plaque biofilm which harbors millions of microorganisms. In addition, the pathogenesis of this disease is greatly influenced by the host immune response that leads to the cyclic destruction and healing pattern. REVIEW RESULTS: Periodontitis is mostly treated through mechanical debridement using surgical and nonsurgical therapy. However, many times, this treatment does not render desired results due to poor patient compliance, altered immune response, or other host-related factors. This leads to the administration of antibiotics as an adjunct to mechanical debridement. Antibiotics are useful in eliminating periodontopathic microbes, but these agents should be cautiously used and prescribed only if indicated. CONCLUSION: Indiscriminate use of antibiotics can lead to unforeseen adverse effects as well as the development of resistant strains of microorganisms. CLINICAL SIGNIFICANCE: Hence, it is crucial for the dentists to know the indications, contraindications, undesirable effects, correct choice, and dosage of the antimicrobial agent before prescribing it to their patients thereby ensuring the success of periodontal therapy. Thus, the clinician should keep in mind that the antibiotics are merely adjuncts to mechanical therapy and not its replacement.

RESUMEN

Poor oral hygiene seems to be the norm in children and teenagers with Down Syndrome (DS). Advances in design and types of toothbrushes may improve biofilm control. This randomized, single-blind, crossover clinical trial evaluated the effectiveness of electric toothbrushes regarding mechanical control of biofilm in children and teenagers with DS and their cooperation. Twenty-nine participants with DS, aged 6 to 14 years, used both types of toothbrushes: electric (ET) and manual (MT). The order of use of the different types of toothbrushes was randomly defined, including a 7-day period with each type with 7-day washout period in between. The Turesky-Quigley-Hein biofilm index was used before and after brushing to assess the effectiveness of the technique. Frankl's behavioral scale was used during toothbrushing to assess the participants' cooperation. Paired T-test, Mann Whitney, Chi-square, and Fisher's Exact tests were applied, with a significance level of 5%. The quantity of dental biofilm was significantly reduced after both brushing techniques (p < 0.001). However, no significant difference was found in total biofilm (ET: 0.73 ± 0.36; MT: 0.73 ± 0.34; p = 0.985) or % biofilm reduction (ET: 72.22%; MT: 70.96%; p = 0.762) after brushing between techniques or in % biofilm reduction between toothbrushes of age groups (6 -9 years, p = 0.919; 10-14 years, p = 0.671). Participants showed similar cooperation level with the two types of toothbrush (p = 1.000). The use of electric or manual toothbrush had no effect on the quantity of dental biofilm removed in children and teenagers with DS, nor did it influence their cooperation during the procedure.

RESUMEN

OBJECTIVE: The objective of the study, which consisted of a motivational lecture and hands-on training, was to evaluate the role of oral hygiene education for adolescents. METHODS: The study population included sixty-two high school students between fourteen and fifteen years of age (thirty males and thirty-two females). The response rate was 76.5%. The measurement of oral hygiene level was performed using the modified Green Vermilion Index (GVI). The values were recorded at baseline, one week, three months, and six months after education through motivational lecture and hands-on training was performed. Descriptive and nonparametric statistical methods were used in statistical analysis. Level of significance was 0.05. RESULTS: At the beginning of the study, the GVI of all examined subjects was 3.52 (SD = 0.70). One week after the motivational lecture and training, it decreased to 2.64 (SD = 0.69). Three months later, the level of plaque index had the lowest value (1.44; SD = 0.66). At the end of the study the level of plaque index increased to 2.52 (SD = 0.86). CONCLUSIONS: A significant oral hygiene improvement in adolescents as a result of education was presented. However, due to a decline in oral hygiene level six months after the education, there is a need for educational programmes continuity.

RESUMEN

INTRODUCTION: Plaque accumulation can cause white spot lesions. Adding nanoparticles to composites can be effective in reducing the number and function of microorganisms. OBJECTIVE: The aim of this study was to evaluate the antibacterial effects of orthodontic composites containing different nanoparticles on Streptococcus mutans at different times. METHODS: Hydroxyapatite, titanium oxides, zinc oxide, copper oxide and silver oxide nanoparticles were prepared at 0.5% and 1% weight concentrations. Accordingly, ten study groups and one control group were obtained. Then, 26 composite discs were prepared from each group. Strain of Streptococcus mutans was cultured, and colonies of Streptococcus mutans were counted. Further bacterial culture was swapped onto enriched Mueller-Hinton agar. The composites were placed on the culture medium, and after incubation the diameter of growth inhibition was measured. To investigate the long-term effect of nanoparticles, the colonies were counted at days 3, 15 and 30. RESULTS: The results showed that 1% copper oxide and 1% silver oxide significantly reduced the number of bacteria (p< 0.05), but there was no significant difference between the other groups and control group (p> 0.05). At day three, there was a significant difference between control group and 0.5% silver oxide, 1% silver oxide and 1% copper oxide groups (p< 0.05). However, colonies had grown in all groups at day 30 but showed no significant difference with control group (p> 0.05). CONCLUSION: Addition of 1% copper oxide and 1% silver oxide has short-term antibacterial effects, so the clinical use of these nanoparticles cannot be justified.

RESUMEN

AIM: To investigate whether the daily use of a spray containing an aqueous extract of Triticum vulgare (TV), belonging to the family of Graminaceae, associated with supervised toothbrushing may improve gingival health in schoolchildren with mixed dentition. MATERIALS AND METHODS: Study design: Randomised, controlled, single-centre, examiner blind, parallel-group study. The study population included 57 schoolchildren with plaque-induced gingivitis randomly allocated to test (n = 29) and control (n = 28) group. Both groups were enrolled in a mechanical plaque control programme for a period of 2 weeks. The test group was also instructed to use a gluten free spray formulation of TV spray twice daily after toothbrushing. Evaluations of plaque index, modified gingivitis index (GI), salivary pH and whole stimulated saliva quantity took place at baseline and after 1 and 2 weeks of study product use. RESULTS: No side effects were observed. Plaque accumulation and GI statistically significantly improved compared with baseline in both groups (all P-values < 0.005), while salivary pH remained nearly unchanged. Between-group differences in index reduction were statistically significant only for GI favouring the test group (P = 0.013). STATISTICS: Repeated-measures ANOVA and the Friedman test were applied to evaluate the influence of time on quantitative variables within each treatment group. Differences between test and control groups were tested using the unpaired t test or the Mann-Whitney U-test with Bonferroni correction. CONCLUSIONS: This study found that TV in spray formulation is safe and effective in controlling gingival inflammation. Thus, it may be a potential adjuvant in the treatment of gingivitis in combination with mechanical plaque control in schoolchildren.

RESUMEN

PURPOSE: To compare the differences of influence of mothers' different socio-demographic background, their oral health status and feeding behavior on their one-month-old infants' risk of dental caries between Shanghai and Kunming, and to explore the factors affecting infants' risk of dental caries in different regions. METHODS: One-month-old infants and their mothers from Huangpu district of Shanghai and Xishan district of Kunming were recruited in the study. Oral plaque samples of mothers and their infants were collected to assess their risk of dental caries. Statistical analysis was performed using SPSS 22.0 software package, and multivariate logistic regression analysis was used to screen the factors affecting the risk of infantile rickets in Shanghai and Kunming. RESULITS: A total of 165 mother-child pairs in Shanghai and 161 mother-child pairs in Kunming participated in the survey, and the proportion of infants who were at high risk of caries was 10.3% and 6.2%, respectively. The result of multivariate logistic analysis indicated that the infants whose mother smoked before pregnancy (OR=6.9, P=0.030) and attained lower education level (OR=6.1, P=0.035) had higher risk of caries in Shanghai; while in Kunming, the infants whose mother had higher DMFS values were at higher risk of caries (OR=1.1, P=0.031). CONCLUSIONS: Factors affecting one-month-old infants' risk of caries in Shanghai and Kunming were pre-pregnancy maternal cigarette smoking, mother's lower education level and mother's dental caries status, respectively.

RESUMEN

Dental calculus has a secondary effect on the pathogenesis of periodontal diseases by harboring bacterial biofilm on its rough surfaces. Consequently, professional removal of both calculus and biofilm is a crucial part of the therapy and prevention of gingivitis and periodontitis. Today, crystal growth inhibitors such as zinc ions in the form of zinc chloride or zinc citrate, and pyrophosphates alone or in combination with copolymer are added to toothpastes to prevent the mineralization of the dental biofilm. In addition, triclosan is used as an antimicrobial agent in combination with copolymer as an additive in toothpastes to reduce the amount of plaque and thus the substrate for calculus formation. In clinical trials, chemical additives have demonstrated an inhibiting impact on calculus formation. However, it must be clarified that in addition to home-based oral hygiene, the formation of dental calculus depends on other factors such as access to professional dental care, diet, age, ethnicity, time since last professional tooth cleaning, systemic diseases or medications. However, since chemical additives in toothpastes do not reach the deeper sites of periodontal pockets, they are recommended for the inhibition of supragingival calculus formation, thus assisting the primary prevention of gingivitis as well as the secondary prevention of periodontal disease.

RESUMEN

PURPOSE: To analyse the effect of information technologies on improving the frequency of the use of dental floss among adolescents. MATERIALS AND METHODS: A randomised, controlled clinical trial was conducted with 291 adolescents (mean age: 16.1 years) in three phases. Phase I involved the application of a questionnaire and clinical examinations using the simplified Oral Hygiene Index and gingival bleeding index. In phase II, the adolescents were randomly allocated to four groups: oral counseling (OR) and the use of an application (App) for smartphones; OR without the app; video (VD) and app; and VD without app. Messages were set through the app for 30 days. Phase III involved the second administration of the questionnaire and clinical examination. The frequency of dental floss use was evaluated in phases I and III. The groups were categorised into the use of technology (VD and/or App) and non-use of technology (OR alone). RESULTS: Statistically significant reductions in the clinical indices were found with all educational methods (p < 0.005) and improvements were found in the use of dental floss (p < 0.001). Moreover, information technologies were associated with an improvement in the frequency of dental floss use (p < 0.033). CONCLUSION: All methods were effective at improving clinical indicators. The use of information technologies can be considered an effective tool for improving dental floss use among adolescents.

RESUMEN

PURPOSE: The effects of three preoperative mouthwashes on salivary bacterial levels were evaluated and compared between subjects with differing periodontal status. MATERIALS AND METHODS: Based on periodontal parameters, periodontally healthy individuals (n = 60) and those with gingivitis (n = 60) and periodontitis (n = 60) were randomly assigned to a single preoperative dose of chlorhexidine (CHX), essential oils (EO), cetylpyridinium chloride (CPC) or negative control mouthwashes. Saliva samples were collected between 8:00 and 11:00 a.m., before and after a single-dose rinse with the respective mouthwash. Total bacterial load and levels of Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Streptococcus oralis were determined by qPCR. Data were statistically analysed using paired t- and Student's t-tests (p < 0.05). RESULTS: CHX, EO and CPC showed greater antimicrobial efficacy than did the negative control. CHX [1226445.53] and EO [1743639.38] provided greater reductions in comparison to both CPC [106302.96] and negative control [37852.46]). CHX provided greater reductions of simultaneous levels of Pg [106326.00], Td [3335841] and Tf [61557.47] in the healthy group, as did EO in the diseased groups. CPC provided the greatest reduction [3775319.36] in the periodontitis group. CONCLUSION: Periodontal status influenced the antimicrobial efficacy of preoperative mouthwashes. Therefore, periodontal status should be taken into consideration by clinicians. The antimicrobial efficacy differed among the agents tested. CHX and EO showed the greatest efficacy. The recognition of periodontal condition by clinicians is mandatory to select the most effective preoperative mouthwash.

RESUMEN

The aim of the study was to determine the likelihood and frequency of complications, the impact of the use of various types of toothbrushes in the dynamics of orthodontic treatment with fixed appliances in patients with a distal permanent bite. The clinical study was conducted on 63 patients of both sexes, aged 11-18 years. Patients received long-term orthodontic treatment for a close tooth position with a distal permanent bite (K07.2) and cleft palate and lip (Q37.1). Three groups were conditionally distinguished depending on the type of toothbrush used for individual oral hygiene: group 1 (n=21) - an orthodontic manual toothbrush (Professor Persin, Spazzolificio Piave S.p.A, Italy); Group 2 (n=22) - an ultrasonic toothbrush (Emmi-dent, EMAG AG, Germany) and group 3 (n=20) - an electric toothbrush (Oral-B Pro-Expert, Procter & Gamble, USA). According to the Kaplan-Meier method, the probability of developing complications of orthodontic treatment was calculated as patients wear braces, and the impact on the effectiveness of orthodontic treatment of using toothbrushes of various types was evaluated. A frequency analysis of the complications of orthodontic treatment for the entire period of wearing fixed orthodontic structures revealed a difference only in respect to enamel demineralization. In group 1, enamel demineralization was more common (42.9%) compared with 2 (9.1%) and 3 (25%) groups (p=0.039). The likelihood of developing gingivitis was higher in group 1, the timing of the development of inflammatory processes in periodontium was also shortened in group 1 compared with groups 2 and 3. The frequency and timing of the development of gingivitis and enamel demineralization depended on the type of toothbrush used in daily oral hygiene. A marked deterioration in the oral hygiene during orthodontic treatment using a manual brush was accompanied by a more frequent development of gingivitis and enamel demineralization.

RESUMEN

The aim of the study was to assess the efficacy of parodontax complex anti-inflammatory toothpaste with fluorine for treatment of moderate catarrhal gingivitis. MATERIAL AND METHODS: Within 6 weeks a group of students was observed, which was divided into 2 subgroups depending on the activity of the carious process and with characteristic changes in crystalloscopy of the oral fluid. Clinical trials of parodontax anti-inflammatory toothpaste with fluorine were conducted. The properties declared by the manufacturer were evaluated using clinical, biochemical, laboratory studies, and criteria-based assessment of crystalloscopic features of the oral fluid. RESULTS: The study revealed a statistically significant correlation of the cleaning ability of the hygiene product and crystalloscopic properties of saliva and changes in the clinical picture of chronic catarrhal gingivitis. With the inclusion of a comprehensive anti-inflammatory toothpaste containing fluorine and natural herbal extracts, a shift in the acid-base balance of the oral fluid to the alkaline side was recorded. CONCLUSION: The improvement in the oral hygiene indices and the resolution of inflammatory processes in periodontal tissues prove the efficacy of comprehensive treatment of chronic gingivitis including parodontax toothpaste.

RESUMEN

OBJECTIVES: Dental research typically targets multiple outcomes. Interdental cleaning devices such as interdental brushes (IB) and water jet devices (WJ) share a sizable portion of the medical device market. However, recommendations for device selection are limited by the conflicting evidence from multiple outcomes in available studies and the lack of an appropriate synthesis approach to summarize evidences taken from multiple outcomes. In particular, both pairwise meta-analyses and single-outcome network meta-analyses can give discordant results. The purpose of this multioutcome, Bayesian network meta-analysis is to introduce this innovative method to the dental research community using data from interdental cleaning device studies for illustrative purposes. METHODS: We reanalyzed a network meta-analysis of interproximal oral hygiene methods in the reduction of clinical indices of inflammation, which included 22 trials assessing 10 interproximal oral hygiene aids. We focused on the primary outcome of gingival inflammation, which was measured by 2 correlated outcome variables, the Gingival Index (GI) and bleeding on probing (BOP). RESULTS: In our previous single-outcome analysis, we concluded that IB and WJ rank high for reducing gingival inflammation while toothpick and flossing rank last. In this multioutcome Bayesian network meta-analysis with equal weight on GI and BOP, the surface under the cumulative ranking curve was 0.87 for WJ and 0.85 for IB. WJ and IB remained ranked as the 2 best devices across different sets of weightings for the GI and BOP. CONCLUSION: In conclusion, multioutcome Bayesian network meta-analysis naturally takes the correlations among multiple outcomes into account, which in turn can provide more comprehensive evidence.

RESUMEN

Purpose: Measurement of dental plaque is frequently used as an indicator of overall oral health. The purpose of this study was to compare a manual (visual) plaque scoring system (University of Mississippi Oral Hygiene Index, UM-OHI) with an innovative automated digital scoring system.Methods: Mechanically ventilated, intensive care unit (ICU) patients (n=79) were the study population. Informed consent was given by the subject's legally authorized representative. Digital images of dental plaque were taken using an intraoral camera; and the quantity of dental plaque was scored using the UM-OHI and with a digitized automated scoring system. Distributions of dental plaque scores from both methods were plotted. Pearson correlation coefficients and intra-class coefficients were calculated between the two methods.Results: Participant mean age was 57.3 years; respiratory failure was the most prevalent admission diagnosis (55.7%). The mean percentage of dental plaque calculated by the manual method was found to be remarkably higher (67.3% ± 18.7%) than the percentage of dental plaque calculated by the automated scoring method (23.7% ± 15.2%) (p<0.0001). Despite remarkably different distributions of plaque scores, both the automated and manual scoring systems demostrated relatively high correlation (r=0.62) and good reliability (ICC=0.63).Conclusion: The automated digital scoring system resulted in a significantly lower overall percentage of total dental plaque as compared to the UM-OHI manual scoring system. While the automated digital scoring system may be more precise than a manual (visual) scoring system, its use should be weighed against the added effort, cost, and expertise required for the method. Further study is needed to determine whether an automated digital scoring system can be commercialized and is warranted for use outside of research settings.

RESUMEN

PURPOSE: To evaluate the safety and efficacy of the ToothWave radiofrequency (RF) toothbrush in the reduction of plaque, calculus and gingival inflammation, as compared to a standard powered toothbrush accepted by the American Dental Association (ADA). METHODS: This was a single-blind, double arm, prospective study. Subjects were randomized to one of two treatment groups, receiving either the RF powered toothbrush or a control powered toothbrush, and performing twice daily brushing for a test period of 6 weeks. Plaque (RMNPI), calculus (V-MI), gingival inflammation (MGI) and bleeding (GBI) were assessed at baseline, after 4 and 6 weeks. Comparisons were completed both within and between each treatment group. Statistical analyses were conducted using the Mann Whitney non-parametric model. RESULTS: 85 subjects completed the study and had fully evaluable data. No significant differences between the groups were found in the baseline scores (P≥ 0.165). Following 6 weeks, the RF test group demonstrated statistically significant reductions in plaque, gingivitis and calculus compared to the control powered toothbrush (P≤ 0.001). Both toothbrushes were well-tolerated and no device-related adverse events were reported. The RF-utilizing powered toothbrush produced statistically significant reductions in dental plaque, calculus deposition, gingival inflammation and gingival bleeding as compared to a control powered toothbrush. CLINICAL SIGNIFICANCE: The RF powered toothbrush used twice daily resulted in an overall improvement in oral health.

RESUMEN

Objective: Power toothbrushes is considered an effective tool for maintaining oral health; however, its efficacy as compared to manual toothbrushes is still not completely clarified. This article aims to evaluate the efficacy of power toothbrushes compared with the manual toothbrushes in terms of plaque, gingivitis and bleeding reduction.Methods: An electronic search was performed on PUBMED, Web of Science, Wiley and Research Gate. Studies comparing the effectiveness of plaque, gingivitis and bleeding reduction between power and manual toothbrushes were included. Results and effect sizes analysis are presented as standard mean difference (SMD), and subgroup analysis stratified by mode of action of the power toothbrush was performed. Study quality and risk of bias were assessed using the Cochrane assessment tool.Results: A total of 21 randomized clinical studies were included. Power toothbrushes were significantly more effective in reducing plaque index (26 trials: SMD = 0.86, 95% CI: 0.58 to 1.14, I2 = 91.5%, p < .0001), gingival index (14 trials: SMD = 0.47, 95% CI: 0.12 to 0.82, I2 = 88.7%, p < .0001), and bleeding index (11 trials: SMD = 0.92, 95% CI: 0.43 to 1.40, I2 = 91.8%, p < .0001) compared with the manual toothbrushes, except that there was no significant differences between the oscillating-rotating toothbrushes and manual toothbrushes regarding gingivitis reduction (7 trials: SMD = 0.07, 95% CI: -0.20 to 0.33, I2 = 57.2%, p = .03).Conclusions: Power toothbrushes is more effective in reducing dental plaque, gingivitis and bleeding compared with the manual toothbrush.
