Relationships between dietary behaviours, oral hygiene and mutans streptococci in dental plaque of a group of infants in southern England

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.

Thirty children (6 to 18 months), enrolled in a dental program since birth, make up the intervention group. Control group consisted of thirty children who were of similar age and gender but had never been to a dental office. The presence of visible dental plaque and the performance of oral hygiene differed statistically between both groups. The dental program was effective in reducing visible dental plaque, and in establishing oral health habits among parents and young children.

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.

Periodontal Condition

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.
