The Impact

Good oral hygiene is an important factor in oral and general health, especially in orthodontic patients, because fixed appliances might impede effective oral hygiene and thus increase the risks of tooth decay, periodontal disease and general health complications. This study investigated the impact of fixed orthodontic appliances on the distribution of dental biofilm in teenagers. Supragingival plaque was assessed at T0, T1 and T2. The distribution of the biofilm was analyzed. Approximal Plaque Index (API) and Bonded Bracket Index (BBI) were used to measure the presence of dental plaque. After insertion of the fixed appliance, the dental plaque indices values in the orthodontically treated group were significantly higher (p < 0.05) than in the control group. Fixed orthodontic appliances caused significant changes in the distribution of the biofilm. This was characterized by the change of location of the dental plaque. In the orthodontic group, we observed an increase in the amount of the supragingival plaque on the vestibular surface of the teeth.

Introduction. Since the discovery that periodontal diseases are caused by microbial plaque the interest of many scientists has been focused on oral antiseptics. There are very few mouthrinses with oral antiseptic effect originally designed in our country. One of these is Ozosept? solution. Objective. This study evaluated the effect of Ozosept? solution (phenol compound) on the oral hygiene and gingival inflammation, in comparison with Hibidex DAP? solution (chlorhexidine digluconate). Methods. Two groups, each of 21 persons, which did not significantly differ concerning Silness-L?e plaque index (PI) and L?e-Sillnes gingival index (GI), used one of the studied oral antiseptic for a 15-day period. Oral hygiene was maintained by subjects' habitual home methods, and no technique of professionally advised brushing was performed during the experimental period. Results. At the end of the study, PI and GI scores were lowered to a statistically high significance in both groups of participants in comparison to the indexes at the beginning of the study. At the end of the study, PI and GI scores did not significantly differ between the two analyzed groups. No side effects, which were recorded in the Hibidex DAP? group (tooth and filling staining 9.5% and 4.74% respectively, transitory tongue numbness 28.6% and reduced taste sensation 14.3%), were registered in the group of subjects using Ozosept? solution. Conclusion. It is concluded that Ozosept? solution is effective in the control of dental plaque - biofilm accumulation and gingival inflammation, and produces no side effects related to chlorhexidine digluconate usage.

Introduction The exact mechanisms by which smoking effects the periodontal tissues are not known. Studies in which plaque or calculus are taken into consideration come to conflicting conclusions regarding effects of smoking. Aim The aim of this study was to examine the oral hygiene and periodontal status in smokers and compare them with nonsmokers. Material and methods The study group comprised 83 smokers and 83 nonsmokers. The mean age (SD) of smokers and nonsmokers was 42,4?7,0 years and 43,7?6,4 years, respectively. The age difference was not statistically significant. The average tobacco consumption of the smokers at the time of investigation was 14 cigarettes a day and they had been regular smokers for 21 years on average. Results The amount of dental plaque was evaluated in accordance with the criteria of Green-Vermillion by using disclosing solution. The periodontal condition was evaluated by Ramfjord Periodontal Disease Index. For gingival recession the distance from the cemento-enamel junction to the gingival margin was determined on mid-buccal and mid-lingual surfaces of all teeth. Each subject was radiographically examined with a full mouth intraoral survey. Alveolar bone loss was determined as the distance from the cemento-enamel junction to the point where lamina dura became continuous with the compact bone of the interdental septum. Mean alveolar bone loss based on all mesial and distal measurements was calculated for each subject. The amount of dental plaque was high in both smokers (2,60,60) and nonsmokers (1,50,70), whereas the differences were statistically significant (p<0.001). Conclusion Periodontal destruction, alveolar bone loss and gingival recession were significantly increased in smokers compared to nonsmokers (p<0.001). It is concluded that differences observed between smokers and nonsmokers with regard to periodontal condition are attributable to differences in oral hygiene. Smoking is a risk factor for periodontal health.

Previous research has shown the inhibitory effects of hop bract polyphenols (HBP) on cariogenic streptococci in vitro, but their effects in humans have not been investigated. This double-blind, crossover clinical study tested the hypothesis that HBP delivered in a mouthrinse suppresses plaque regrowth in humans. Twenty-nine healthy male volunteers had all plaque removed, and refrained from all oral hygiene for 3 days, except for rinsing with a mouthrinse containing 0.1% HBP or a placebo. The results showed that the mean amount of plaque assessed by the Patient Hygiene Performance score after the volunteers used the HBP mouthrinse was significantly less than that after they used the placebo (p < 0.001). The number of mutans streptococci in the plaque samples after volunteers used the HBP mouthrinse was significantly lower than that after they used the placebo (p < 0.05). These findings suggested that HBP, delivered in a mouthrinse, successfully reduced dental plaque regrowth in humans.

Introduction: Indexes of oral hygiene and dental plaque measurements have been developed since the 1960s in assessing an individual's oral hygiene, and to evaluate the effectiveness of programs to promote oral health and to measure the effectiveness of therapeutic methods. The Dental School at Universidad del Valle and the Pacífico Siglo XXI research team have developed an oral hygiene index for community use and evaluate its sensitivity and specificity versus three other indexes used in studies worldwide. Methodology: A group of seven students in their fifth year of dentistry were standardized for the registration of pattern indexes (gold standard), the O´Leary index, detritus index by Greene & Vermillion index, Silness & Löe index, and the oral hygiene index for community use (CPI) achieving a match with Kappa values from 0.83, 0.81, 0.71, 0.94, and 0.86, respectively. A total of 83 fifth grade, primary school children were examined with parental consent; the data was recorded and taken to a database that was processed with a SSPS version 17 program. Results: The plaque rate in the children evaluated was 80%. No significant differences were found between the gold standard, the O´leary index, and the oral hygiene index for community use. The sensitivity of the indices evaluated was: 96.8 (95% CI 95.5-97.9) for the O'Leary index; 95.1 (95% CI 92.5-97.4) for the CPI; 75.2 (95% CI: 73.1-77.1) Greene & Vermillion detritus index, and 69.5 (95% CI 66-73) for the Silness & Löe index. The average specificity of 75 had no significant differences among the indexes. Conclusions: The Silness & Löe and Greene & Vermillion indexes are less sensitive with significant differences in relation to the O´Leary index and the plaque community index.

BACKGROUND Dental diseases can be prevented through the management of dental plaques. Dental plaque can be identified using the light-induced fluorescence (LIF) technique that emits light at 405 nm. The LIF technique is more convenient than the commercial technique using a disclosing agent, but the result may vary for each individual as it still requires visual identification. OBJECTIVE The objective of this study is to introduce and validate a deep learning–based oral hygiene monitoring system that makes it easy to identify dental plaques at home. METHODS We developed a LIF-based system consisting of a device that can visually identify dental plaques and a mobile app that displays the location and area of dental plaques on oral images. The mobile app is programmed to automatically determine the location and distribution of dental plaques using a deep learning–based algorithm and present the results to the user as time series data. The mobile app is also built with convergence of naive and web applications so that the algorithm is executed on a cloud server to efficiently distribute computing resources. RESULTS The location and distribution of users’ dental plaques could be identified via the hand-held LIF device or mobile app. The color correction filter in the device was developed using a color mixing technique. The mobile app was built as a hybrid app combining the functionalities of a native application and a web application. Through the scrollable WebView on the mobile app, changes in the time series of dental plaque could be confirmed. The algorithm for dental plaque detection was implemented to run on Amazon Web Services for object detection by single shot multibox detector and instance segmentation by Mask region-based convolutional neural network. CONCLUSIONS This paper shows that the system can be used as a home oral care product for timely identification and management of dental plaques. In the future, it is expected that these products will significantly reduce the social costs associated with dental diseases.

To estimate the amount of bacteria present in patients wearing metallic and ceramic brackets. The objective of the present study is to investigate the amount of bacteria in patients wearing fixed orthodontic appliance. The fixed orthodontic appliance is the treatment of conditions like malocclusion. It includes brackets, tubes, band and ligating materials and archwires. Composite is used for bonding the brackets to the teeth surface, and it also induces the formation of plaque. Dental plaque is the main aetiology for Causing gingivitis. This study shows that the metallic and ceramic brackets worn by the patients were contaminated with various microorganisms. The main focus of the study is to create awareness among patients with fixed orthodontic appliance and to improve their oral hygiene and to prevent periodontal problems.
