Oral hygiene habits of 11-year-old schoolchildren in 22 European countries and Canada in 1993/1994.

This study is part of the Cross-National Survey on Health Behaviour in School-aged Children--a WHO Collaborative Study, which started in 1982. The aim of the study was to describe the oral hygiene habits (toothbrushing and flossing) of 11-year-old schoolchildren in 22 European countries (Austria, Belgium, the Czech Republic, Denmark, Estonia, FInland, France, Germany, Greenland, Hungary, Israel, Latvia, Lithuania, Northern Ireland, Norway, Poland, Russia, Scotland, the Slovak Republic, Spain, Sweden, and Wales) and Canada. The data were collected from standardized anonymous questionnaires in school classrooms during the 1993-1994 school year. At least 1300 school children, representing the whole country, participated in the study in each country. Oral hygiene habits were analyzed according to gender, age, country, school performance, and family economy. The children brushed most favorably in Sweden, Denmark, German, Austria, and Norway (83-73% brushed twice a day). More-than-once-a-day toothbrushing was especially uncommon (from 26 to 33%) among boys in Finland, Lithuania, Russia, Estonia, and Latvia. Toothbrushing frequency differed significantly according to school performance in Canada, the Czech Republic, Scotland, Poland, Northern Ireland, and Wales and between different socio-economic groups in Northern Ireland, Wales, the Czech Republic, Scotland, Poland, and Russia. Use of dental floss was rare. In general, flossing was less frequent among boys than among girls. Daily flossing was most common among Canadian adolescents (25%). In conclusion, there are considerable differences in toothbrushing frequency among children in European countries.

Effectiveness of mechanical tongue cleaning on oral levels of volatile sulfur compounds.

BACKGROUND: Mechanical tongue cleaning may be an effective method for decreasing oral levels of volatile sulfur compounds, or VSC, and oral malodor. The authors conducted a study to compare the effectiveness of a specially designed tongue cleaner (One Drop Only Tongue Cleaner, One Drop Only, Berlin), a tongue scraper and a toothbrush in reducing oral VSC levels. METHODS: In this balanced, crossover study, 30 subjects had four morning appointments each with a waiting period of one week between appointments. At each appointment, a dental professional performed a single standardized tongue cleaning procedure using one of the cleaning tools. The authors monitored the subjects' oral VSC values using a portable sulfide monitor until their baseline VSC values were reached. RESULTS: The baseline values showed no significant difference between the three groups. The tongue cleaner and the tongue scraper (42 percent and 40 percent, respectively) reduced oral VSC levels more than the toothbrush (33 percent) did. Reduced VSC values could be detected significantly longer after using the tongue cleaner than after using the tongue scraper or the toothbrush. The authors, however, could not detect a significant VSC reduction for more than 30 minutes in any of the subjects. CONCLUSIONS AND CLINICAL IMPLICATIONS: The tongue cleaner, a combination brush and scraper, was slightly more effective in reducing oral VSC levels than were the tongue scraper and a regular toothbrush. Because of the limited duration of the effect, however, the clinical efficacy on the reduction of oral malodor remains questionable.

Mechanism of irrigation effects on gingivitis.

Although gingivitis is initiated by plaque and plaque removal controls gingivitis, gingival irrigation with water has been shown to reduce gingivitis without reducing plaque. This study attempted to explore possible mechanisms involved in the treatment of gingivitis by water irrigation. Patients (n = 125) with more than 20 teeth, less than 4 sites with probing depth (PD) deeper than 6 mm, bleeding on probing (BOP) frequency of 30% or higher, and no systemic disease were randomized to one of four treatment groups: toothbrushing alone (brush), toothbrushing plus chlorhexidine 0.12% rinse 2x/day (CHX), toothbrushing plus water irrigation 1x/day (irr+H2O), or toothbrushing plus chlorhexidine 0.04% irrigation 1x/day (irr+CHX). Six sites/tooth were examined at baseline, and at 3 and 6 months for BOP and PD using an automated probe, and for gingival index (GI) and plaque index (PI) by standard means. A prophylaxis and oral hygiene instructions were provided after baseline and 6 month measurements. Subgingival microbial samples and crevicular fluid (GCF) were collected from 2 teeth/subject at each time point. Microbial samples were processed for anaerobic culture and the predominant cultivable flora was determined. CHX and irr+CHX had a 30 to 35% decrease in mean PI, while brush and irr+H2O had only a 12 to 16% decrease. BOP was reduced by 14% in the brush group and 23 to 24% in the other groups. GI was significantly correlated with PI in the brush, CHX, and irr+CHX groups, but not in the irr+H2O group. Prevotella intermedia was significantly reduced in both irrigation groups, but not CHX or brush groups.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of an oral health promotion program for people with psychiatric disabilities.

Oral health programs for people with psychiatric disabilities are rare. This study examined the feasibility efficacy of an oral health intervention for people with psychiatric disabilities. Fifty individuals were recruited and randomly assigned to receive education, reminder system and mechanical toothbrush or just the mechanical toothbrush. 42 completed the study. Plaque index scores recorded at baseline and after 4 weeks indicate a statistically significant improvement for both groups but those in the enhanced intervention improved significantly more. The results suggest the mechanical toothbrush improves the oral hygiene of people with psychiatric disabilities. The combination of mechanical toothbrush, dental instructions and reminders result in additional improvements.

Improving quality and efficiency in oral hygiene.

A large percentage of the residents in long-term care facilities are unable to achieve an acceptable level of oral hygiene due to mental and physical incapacities and must thus rely on nursing staff for daily oral care. Significant morbidity is associated with chronic inadequate oral hygiene. In addition, a lack of self-esteem related to poor dental status has been observed in some nursing home patients, leading to withdrawal from social interaction and personal isolation. The Collis Curve toothbrush removed more plaque than the straight bristle toothbrush. The curved bristle toothbrush was well received by the residents and well accepted by the nursing staff. A clinically significant number of staff reported that the curved bristle toothbrush made their job easier. Monitoring of the nurses' aides' brushing techniques during the study caused them to provide more effective oral hygiene than prior to the study. The importance of proper oral hygiene must be monitored and supported by nursing supervisors, regardless of the type of brush, used to achieve acceptable levels of oral hygiene.

Durability of FTLA treatment as a medicament for dentin hypersensitivity--abrasion resistance and profiles of fluoride release.

The purpose of this study was to evaluate the durability of tubules occluded with FTLA treatment by toothbrush abrasion test on the applied surface and by measuring fluoride release from the FTLA components. Dentin specimens with simulated hypersensitive surfaces were treated with APF containing tannic acid. After which, the specimens received lanthanum-chloride-with-powdered-fluoroapatite-glass-ceramics treatment. The specimens were subjected to toothbrush abrasion test up to 6,000 strokes. SEM observation revealed that dentinal tubules of the FTLA treated specimens were completely occluded with fine deposits even after toothbrush abrasion of 6,000 strokes. EPMA analysis revealed that fluoride, lanthanum, and aluminum were the main FTLA components on the dentin surface after 6,000-stroke abrasion. To measure fluoride release from the FTLA components, a slurry was enclosed in a cellulose tube and suspended in deionized water at 37 degrees C. After fluoride was dialyzed against deionized water, a high concentration of fluoride was found to be released from FTLA the components, indicating FTLA treatment's prominent durability. These results suggested that FTLA treatment has a superior resistance against toothbrush abrasion and a high fluoride-releasing performance. These characteristics lend much weight to showing that the FTLA method is an effective and durable medicament for dentin hypersensitivity.

Laboratory evaluations of three dentifrices with polishing or brushing.

The purpose of this study was to determine the depth of deposit removal of three dentifrices using a dental felt polishing tip or an Oral-B P 35 toothbrush. The dentifrices were compared using a laboratory method which simulates clinical tooth polishing or toothbrushing procedures, and utilizes a pressure-sensitive paper that records the depth of deposit removal. Each polishing time was conducted for five seconds; toothbrushing time was 15 seconds. Both polishing and toothbrushing were performed at a weight of 250 grams. Depth of Deposit Removal (DDR) was recorded using a 0-4 scale from a comparative color chart. The dentifrices evaluated were Arm & Hammer Dental Care, Colgate Regular, and Crest Regular. Twenty-four replicates of each dentifrice, tested undiluted, were performed. Results indicated that dentifrice efficacy was ranked numerically as Arm & Hammer Dental Care > Colgate Regular > Crest Regular. In all of the assays the Arm & Hammer Dental Care dentifrice had significantly (p < 0.01-0.001) higher DDR mean values compared to the Colgate Regular and Crest Regular dentifrices. The Colgate Regular dentifrice was significantly (p < 0.01-0.001) superior to the Crest Regular dentifrice in the assays conducted.

[The clinical and microbiological evaluation of the efficacy of oral irrigation on the periodontal tissues of patients wearing fixed orthodontic appliances].

The aim of the present study has been the evaluation of the effectiveness of oral irrigation with or without toothbrushing and dental flossing, in individuals treated with fixed orthodontic appliances, on controlling the development of dental plaque and, hence, of gingivitis. Eight individuals with a good general and oral status have been chosen. Before the experimental period, they received instructions about oral hygiene with toothbrushing and dental flossing and then they have been monitored to verify they were doing well. At the time T0, the upper tooth have been banded, three Periodontal Indexes (Plaque Index according to Silness and Loe, Modified Gingival Index according to Lobene and Gingival Bleeding Index according to Ainamo and Bay) registered and subgingival plaque samples from the premolars' gingival sulcus collected in order to point out the total anaerobes bacterial counts, the rates of motile bacteria, spirochetes, Gram positive and Gram negative cocci and bacteria, by means of optical and dark field microscopy and of cultural methods. For their oral hygiene, the patients had to use, in the right side toothbrush and dental floss (Control 1), in the left side the oral irrigator alone (Test 1). One month later (time T1), the lower teeth have been banded, too. In the right side the patients had to use toothbrush and dental floss (Control 2), while in the left one they used the same devices as Control 2 plus the oral irrigator (Test 2). At the time T1 Periodontal Indexes and Microbiological analyses have been extended to all the four quadrants.(ABSTRACT TRUNCATED AT 250 WORDS)

Refinement of the Modified Navy Plaque Index to increase plaque scoring efficiency in gumline and interproximal tooth areas.

To improve the assessment of plaque present on teeth, a new index, based on the original Modified Navy Plaque Index, has been developed. The primary modifications to the original Modified Navy Plaque Index were: (1) extending areas F (distal) and D (mesial) into the region just below the interproximal contact point, and (2) extending areas C and A so as to increase the gumline (or marginal gingiva) region. The new index assesses the amount of plaque in the tooth area bounded by the tooth contact, the free gingival margin, and mesial or distal line angles. The use of this new index enables the examiner to evaluate and record both the gumline (or marginal areas) and interproximal areas of the tooth, thus giving these an anatomical areas an increased importance. A pilot clinical assessment study was conducted to utilize this new index in evaluating the plaque removal efficacy of five manual toothbrushes. The results from this pilot study indicated that, when the new plaque scoring index was used, significant differences between pre-toothbrushing and post-toothbrushing plaque scores (as well as among toothbrush groups) could be demonstrated. Further, these differences (plaque removal efficacy) were demonstrated on an interproximal (mesial and distal) basis and a gumline (or gingival margin) basis, as well as on a whole mouth basis.

Plaque removing capacity of a novel high pressure water irrigator.

PURPOSE: To evaluate the capacity of a novel oral water irrigator to remove established plaque deposits. METHODS: The study was designed as a randomized two-treatment, crossover, examiner-blinded clinical trial. The plaque removing capability of a prototype oral irrigator was compared to a conventional electric toothbrush. After 48 hours of plaque accumulation the 35 subjects were randomly assigned to professional plaque removal by either oral irrigation or by electric toothbrushing for a timed 2-minute total cleaning. Pre- and post cleaning plaque was disclosed and gingival abrasions were identified. Plaque was assessed on gingival and approximal surfaces of the oral and buccal sites according to the Rustogi et al modification of the Modified Navy Plaque Index. The assessment of gingival abrasions was performed according to the method introduced by Danser et al. RESULTS: The overall plaque removing capacity of the oral irrigator reached approximately 40.7 +/- 16.7% as compared to 71.6 +/- 11.5% by the electric toothbrush. Similar effects were observed for the gingival and approximal areas. The electric toothbrush caused significantly more gingival abrasions than the oral irrigator.

The relationship between chewing sticks (Miswak) and periodontal health. 3. Relationship to gingival recession.

Aggressive or improper toothbrushing techniques may have a detrimental impact on the gingiva. The purpose of this study was to examine the relationship between chewing sticks (Miswak) and gingival recession. Gingival recession was measured on the mid facial surfaces of the incisors, canines, and premolars in 238 patients presenting for routine dental appointments. All patients had been interviewed previously regarding their oral hygiene habits and use of Miswak. Patients were divided into three groups: Miswak group, toothbrush group, and Miswak/toothbrush group. The Miswak users had significantly more (P less than or equal to .05) sites gingival recession than did the toothbrush users. Furthermore, the severity of the recession was significantly more (P less than or equal to .05) pronounced in the Miswak users than it was in the toothbrush users.

A comparative study of the efficacy of plaque control by a chewing stick and a tooth brush.

The purpose of this study was to compare the efficacy of a chewing stick and a tooth brush in plaque control. The study composed of two groups of 11 and 8 children aged 13 to 16 years who were randomly selected from a peri-urban school near Nairobi. Results showed that, except for the participants with moderate amounts of plaque, the net changes in the mean number of surfaces with a given plaque score were more when the participants were using a toothbrush than when they were using a chewing stick. For the group of participants who started using a chewing stick before they changed to the toothbrush, there were no significant net changes in the mean number of surfaces with a given plaque score except for those surfaces which had mild plaque deposits. It is concluded that for the patients with severe plaque deposits, the toothbrush is more efficacious than the chewing stick in plaque control. However, for those patients with moderate plaque deposits, the chewing stick is as efficacious as the toothbrush in plaque control.

Abrasive properties of commonly used dentifrices.

This study was conducted to examine the effect of various dentifrices on the abrasion of acrylic resin and extracted human tooth. The influence of the difference in the hardness of the filament of the toothbrush on the abrasion was also studied, using three kinds of toothbrushes. The specimens (acrylic resin and extracted human tooth) were brushed 3,000 times by the back- and -forth stroke movement using a toothbrushing machine for two hours. The surface irregularities of the specimen were analyzed by the surface analyzer and observed by the scanning electron microscopy before and after the brushing procedure. Moreover, the weight loss of the test specimens of the acrylic resin materials was determined, weighing them by a microbalance before and after brushing. The abrasiveness of the dentifrices showed a wide range, but the abrasiveness of the toothbrush itself was not observed. All dentifrices except one which did not contain the abrasive materials had abrasive effects on both the acrylic resin and human tooth. There was a high correlation (r = 0.96) between the weight loss and the surface irregularities in the case of acrylic resin.

Dental health habits in Austria, England, Finland and Norway.

Individually, people can prevent dental caries by sugar restriction and periodontal disease by toothbrushing. The aim of this study was to determine the toothbrushing frequency and consumption of sweets and soft drinks in some European countries. The data were obtained during the winter of 1983-84 from schoolchildren aged 11.5, 13.5 and 15.5 in Austria, England, Finland and Norway. Except for England, the samples were nationally representative. The questionnaires were completed at school. Dental health habits apparently were best in Norway, as the toothbrushing frequency was highest and the consumption of sweets and soft drinks was lowest. The toothbrushing frequency of boys was lowest in Finland. The consumption of sweets and soft drinks was very high in Austria and England. Such international comparisons should be used when evaluating and directing national programmes of preventive dentistry.

Clinical and cost effectiveness of the counter-rotational brush in private practice.

There have previously been no studies on the cost effectiveness of the use of a counter-rotational toothbrush (INTERPLAK Home Plaque-Removal Instrument), which has been demonstrated to be more effective than ordinary toothbrushes in reaching plaque-removal and gingival-health goals. Killoy et al studied the costs of required periodontal treatment for 32 patients with moderate periodontitis at two corporate capitation dental centers. The subjects were divided into two groups, a test group that brushed with a counter-rotational toothbrush and one that brushed with a manual toothbrush. Probing depth, attachment levels, and plaque and bleeding indexes in the test brush group were better than those in the control group. The end result was a mean reduction of $535 in the cost of periodontal treatment that had been planned before using the counter-rotational brush over 18 months, while the group using the manual brush experienced a mean increase of $11 in required treatment over original plans. Furthermore, the test group reached a state of gingival health, but the control group did not. The study concluded that the counter-rotational brush is cost effective.

Oral health and dental behaviour in 11-year-old children of different ethnic groups.

This investigation was first, to assess the oral health of 11-year-old children in four ethnic groups in Amsterdam; second, to assess their dental behaviour and third, to identify potential determinants of frequency of toothbrushing. Representative samples of 97 Surinamese, 209 Moroccan, 128 Turkish and 102 Dutch children were examined orally and asked to complete a questionnaire. Results showed that Turkish and Moroccan children had higher mean DMFT and DMFS scores than the Surinamese and the Dutch children. The mean plaque scores in the Turkish and Moroccan children were higher than those in the other two groups. Large differences in frequency of toothbrushing were found between the four ethnic groups, the Surinamese and Dutch children claimed to be the more regular brushers. Logistic regression analysis showed that the frequency of toothbrushing was related to the children's attitude towards toothbrushing and not to parental influence.

Effects of nine weeks' use of a new stabilized stannous fluoride dentifrice on intrinsic plaque virulence expressed as acidogenicity and regrowth: a modified PGRM study.

A new stabilized stannous fluoride dentifrice, currently marketed as Crest Gum Care has been examined for its effects on intrinsic plaque metabolic and regrowth activity and effects on plaque resistance to SnF2 throughout nine weeks of toothbrushing. Subjects brushed their teeth 1 X, 2 X or 3 X/day with stabilized stannous fluoride dentifrice or placebo dentifrice for nine weeks, presenting in the morning on weeks 3, 6-9 for plaque sampling. Following nine weeks, subjects were crossed-over and repeated the experiment on their alternative assigned product (active SnF2/placebo). Sampled dental plaques were evaluated for standardized glycolysis and regrowth activity using the "Plaque Glycolysis and Regrowth Method" (PGRM). Following the second nine-week treatment period, subjects concluding either placebo or SnF2 toothbrushing participated in a single-treatment PGRM experiment using stabilized stannous fluoride dentifrice. Toothbrushing with stabilized stannous fluoride dentifrice in this experiment produced significant and sustained reductions in both plaque glycolytic and regrowth activity as compared to placebo treated plaques. In the concluding single-brushing PGRM experiment, SnF2 dentifrice was shown to produce equal inhibitory actions in plaque from subjects completing stannous fluoride or placebo treatments. This result confirmed that nine weeks toothbrushing with stabilized stannous fluoride dentifrice produced no development or resistance of plaque to SnF2 inhibition. These results support the strong in vivo antimicrobial actions of the stabilized stannous fluoride dentifrice, Crest Gum Care.

Antimicrobial effects of a stabilized stannous fluoride dentifrice in reducing plaque acid production--a single-brushing PGRM study.

A Plaque Glycolysis and Regrowth Method (PGRM) has been used to evaluate the in vivo antimicrobial activity of a new stabilized stannous fluoride dentifrice in comparison to a control dentifrice (Regular Crest, containing NaF) and a second commercial dentifrice containing SnF2. In the method, plaque collected from subjects prior to toothbrushing served as control for subsequent plaque samples collected following toothbrushing with assigned formulations. Inhibition of plaque metabolic activity was determined by the comparative acidogenicity of normalized plaque samples as contrasted with control plaques incubated similarly. Results from a sixteen-person cross-over study demonstrated that the improved stabilized stannous fluoride dentifrice significantly reduced plaque metabolism of sucrose in comparison to both placebo and commercial SnF2 dentifrice formulations following a single toothbrushing with 2.5 grams of dentifrice for over 90 minutes following treatment. These results support the strong antimicrobial activity of the stabilized stannous fluoride dentifrice, currently marketed as Crest Gum Care, in inhibiting plaque metabolism/acid production following in vivo toothbrushing.
