Effects of Multibracket Orthodontic Treatment versus Clear Aligners on Periodontal Health: An Integrative Review. Dent J (Basel) 2022; 10:dj10100177. [PMID: 36285987 PMCID: PMC9600623 DOI: 10.3390/dj10100177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 09/13/2022] [Accepted: 09/14/2022] [Indexed: 11/23/2022] Open
Abstract
Objective: This integrative review aimed to identify studies comparing the periodontal health in patients wearing multibracket orthodontic appliances and clear aligners. Materials and methods: An integrative literature search was performed through different databases, PubMed/Medline, PMC, and the Cochrane Library. This work was submitted to a search strategy following the PICO method and included the focus question: “Could the chosen orthodontic appliance change significantly the oral hygiene of the patient, impairing the periodontal health?” This work included analytical and controlled studies on humans published between 2005 and 2020, in the English language, establishing a comparison of the periodontal status in patients undergoing orthodontic multibracket and clear aligners therapies. The main periodontal indexes assessed were plaque index (PI), pocket depth (PD), gingival index (GI), and bleeding on probing (BoP). Results: The electronic research displayed 386 articles on PMC, 106 on PubMed, and 40 on the Cochrane Library. After removal, just 25 articles were selected for full-text screening, but just eight studies were eligible for this integrative review. It was enumerated that 204 patients were treated with aligners and 294 with multibracket orthodontic appliances, mainly elastomeric ligated brackets. Only the plaque index displayed a significant difference between the two groups and general data obtained showed a better control for periodontal health in the clear aligners. Limitations such as age, malocclusion severity, therapeutic choice, and different time measure was observed. In addition, the oral hygiene instruction and follow-up by a professional were different, and the role of malocclusion was not present in the studies. Conclusions: Within the limitations of this study, better results for periodontal health were found in the clear aligners. Therefore, more studies are necessary to affirm that aligners are synonymous with better gingival conditions in comparison with multibracket appliances. Other variables such as oral hygiene instructions, motivation, and supportive treatment tend to be more prevalent than the type of appliance itself in the periodontal evaluation.

Söderling E, Pienihäkkinen K. Effects of xylitol chewing gum and candies on the accumulation of dental plaque: a systematic review. Clin Oral Investig 2022; 26:119-129. [PMID: 34677696 PMCID: PMC8791908 DOI: 10.1007/s00784-021-04225-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 10/12/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVES A systematic review of published data was conducted with the aim of assessing the effects of xylitol consumption on the amount of dental plaque. MATERIALS AND METHODS Electronic and hand searches were performed to find clinical studies concerning the effects of xylitol chewing gum or candies on dental plaque. Prospective randomized controlled clinical trials published between 1971 and 2020 conducted in healthy subjects were included in the review. RESULTS The initial search identified 424 xylitol articles. After applying inclusion and exclusion criteria, altogether 14 articles (16 studies) were reviewed. The review identified 12 of the total of 14 xylitol chewing gum studies as having fair or high quality. In 13 of the 14 chewing gum studies, xylitol gum decreased plaque accumulation. In six studies, xylitol gum chewing decreased plaque compared to sorbitol gum, and in three studies compared to gum base/no gum. In three fair-quality studies conducted with xylitol candies, plaque accumulation did not change. CONCLUSIONS Habitual xylitol gum chewing appears to show plaque-reducing effects that differ from those of sorbitol gum. This suggests specific effects for xylitol on plaque accumulation. Xylitol candies appear not to decrease plaque. The heterogeneity of the studies warrants further research. Clinical relevance Habitual xylitol gum chewing is likely to decrease plaque.

The Relationship of Orofacial Pain and Dental Health Status and Oral Health Behaviours in Facial Burn Patients. Pain Res Manag 2021; 2021:5512755. [PMID: 34055118 PMCID: PMC8123994 DOI: 10.1155/2021/5512755] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 02/24/2021] [Accepted: 05/03/2021] [Indexed: 12/02/2022]
Abstract
This study aims to examine the association of orofacial pain and oral health status and oral health behaviours in facial burn patients. The participants in this cross-sectional study were randomly recruited from the Burn Care Center, Institute of Medical Sciences, Islamabad, Pakistan. An intraoral evaluation was carried out to record the DMFT and OHI-S. A self-administered questionnaire was used to collect information on sociodemographic status, brushing frequency, and dental visits. Orofacial pain during mandibular movement was assessed using the Visual Analogue Scale (VAS). Psychological status was assessed using the Generalized Anxiety Disorder Scale and Impact of Events Scale. ANOVA and simple and multiple linear regression tests were used to analyse the data. From the 90 facial burn patients included, the majority were below 34 years of age, female, single or divorced, and unemployed. The mean DMFT was 10.7, and 71% had poor oral hygiene. 56% of the participants had moderate-to-severe anxiety, and 68% had posttraumatic stress disorder. 53% of the participants had moderate-to-severe pain during mouth opening or moving the mandible with a mean score of 41.5. Analyses showed that orofacial pain was associated with less frequent brushing, irregular dental visits, greater DMFT score, and more plaque accumulation (OHI-S). It was also associated with employment status, the severity of a burn, anxiety, and stress. The treatment and management of dental and oral conditions in burn patients need judicious balance in controlling and accurate assessment of the pain and improving psychological problems in burn patients.

Abstract
AIMS The aims of the present study were to assess the prevalence and pattern of gingival bleeding on probing (BOP) and to evaluate the effect of oral health behavior and demographic determinants on gingival health in 11-16-year-old school children in Chandigarh, India. METHODS A cross-sectional study, using stratified random sampling, was conducted across two age groups, 11-13 years and 14-16 years, and two socioeconomic strata: upper and lower. The World Health Organization (WHO) Oral Health Questionnaire for Children was used to record the data, and the WHO Community Periodontal Index (modified) was used to assess gingival BOP. RESULTS Among all the 2294 children examined, an estimated 54.2% had gingival BOP. The odds of BOP were also higher in the younger age group (odds ratio [OR]: 1.261, 95% confidence interval [CI]: 1.068-1.487, P = 0.006), higher for boys (OR: 1.200, 95% CI: 1.017-1.416, P = 0.031), and lower in the upper strata (OR: 0.805, 95% CI: 0.682-0.951, P = 0.011). Gingival BOP was 58.5% in the mandibular and 41.5% in the maxillary arch (P < 0.0001); χ2 -test found tooth cleaning frequency to be a significant contributing factor for gingival BOP (P = 0.014). CONCLUSIONS An inverse co-relation of gingival BOP with age, socioeconomic status, and a higher prevalence in boys was observed, necessitating periodic preventive dental education, particularly focusing on the target group. Additionally, early screening and prompt treatment to intercept the disease is advocated.

Abstract
Food additives used to preserve flavor or to
enhance the taste and appearance of foods are
also available in oral hygiene products. The aim
of this review is to provide information concerning
food additives in oral hygiene products and their
adverse effects. A great many of food additives in
oral hygiene products are potential allergens and
they may lead to allergic reactions such as urticaria,
contact dermatitis, rhinitis, and angioedema. Dental
practitioners, as well as health care providers, must
be aware of the possibility of allergic reactions due
to food additives in oral hygiene products. Proper
dosage levels, delivery vehicles, frequency, potential
benefits, and adverse effects of oral health products
should be explained completely to the patients. There
is a necessity to raise the awareness among dental
professionals on this subject and to develop a data
gathering system for possible adverse reactions.

Abstract
Objective: In general, chemical plaque agents have been used in mouthwashes, gels, and dentifrices. In some situations, application of mouthwashes and dentifrices can be difficult. Therefore, different approaches for oral health-care have been needed. The aim of this study was to evaluate the effect of propolis chewing-gum compared to propolis-containing mouthwash on gingival inflammation and plaque accumulation on patients that refrained from daily oral hygiene procedures for 5 days. Materials and Methods: 10 college students with systemically healthy and very good oral hygiene and gingival health were included in this randomized, single-blind, crossover 5-day plaque regrowth with a 3-day washout period clinical study. After plaque scores were reduced to zero, participants were asked to refrain from oral hygiene procedures and allocated to either propolis mouthwash or chewing-gum group. Chewing-gum was performed after meals 3 times a day for 20 min mouthwash group was instructed to rinse mouthwash 2 times a day for 1 min. On day 5, the clinical periodontal measurements containing plaque and gingival indexes were taken from the participants. Results: The both plaque and gingival indexes of propolis mouthwash group were significantly lower than that of the propolis chewing-gum group (P = 0.005). Conclusion: It was demonstrated that the propolis mouthwash was more effective than the propolis chewing gum on the plaque inhibition and the gingival inflammation.

Abstract
OBJECTIVE The aim of this study was to compare the effect of two sugar-substituted chewing gums besides toothbrushing on different clinical, microbiological, and biochemical caries- and gingivitis-related variables. MATERIALS AND METHODS The study was designed as a double-blind, randomized, controlled trial with three parallel arms. A total of 130 dental students, who volunteered after signing an informed consent, were randomly allocated to receive one of the following interventions: hexitol-sweetened gum containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), pentitol-sweetened gum containing no CPP-ACP, and control group with no gum. Subjects within the experimental groups chewed two gum pellets for 20 min three times a day after meals. The daily consumption level of both polyols was 6.0 g. Clinical examinations and salivary samplings were conducted at baseline and after 30 days of gum use. Pre- and post-intervention stimulated whole saliva samples were quantified for calcium/phosphate ionic concentration, total facultative bacterial load, Streptococcus mutans/Lactobacillus spp. counts, and Gram-negative percentage. RESULTS A statistically significant reduction in visible plaque score was displayed in the hexitol/CPP-ACP gum group after the intervention when compared with baseline, but the order of the effect was in the same order as the differences between the groups at baseline. A similar tendency was seen in both the pentitol/non-CPP-ACP gum and control groups regarding total salivary facultative bacterial load and S. mutans count, but median values of these parameters were more significantly reduced in the pentitol/non-CPP-ACP gum group in comparison with those of the control group. Alterations of salivary Lactobacillus spp. were demonstrated only in the pentitol/non-CPP-ACP gum group. CONCLUSION Although these findings might indicate that a 30-day protocol of daily chewing of pentitol-sweetened gum containing no CPP-ACP might have some a reducing effect on the salivary levels of facultative bacteria, S. mutans and Lactobacillus spp., there was only a marginal, if any, benefit from the chewing gums under study on some microbiological caries- and gingivitis-related variables. CLINICAL RELEVANCE Taking into account that for transferring results into clinically relevant conclusions the findings need to be strong and consistent, adhering to single significant differences appears not appropriate. Hence, the clinical significance of chewing gums as an adjunctive tool for daily oral care remained questionable.

Abstract
OBJECTIVE The aim of this study was to systematically review the current literature on the clinical effects of sugar-free chewing gum on plaque indices and parameters of gingival inflammation. MATERIAL AND METHODS The MEDLINE-PubMed, Cochrane-CENTRAL and EMBASE databases were searched up to 20 April 2012 to identify any appropriate studies. Plaque indices and parameters of gingival inflammation were selected as outcome variables. RESULTS An independent screening of the 594 unique titles and abstracts identified six non-brushing and four brushing studies that met the eligibility criteria. In the non-brushing studies, the use of chewing gum did not significantly affect the parameters of interest. In the descriptive analysis of the brushing studies, four of five comparisons showed a statistically significant effect in favour of the sugar-free chewing gum with respect to plaque scores. The meta-analysis for the Quigley & Hein (J Am Dent Assoc 1962; 65: 26) plaque index scores in the brushing studies also showed a significant difference (DiffM -0.24, 95% CI [-0.41; -0.08]). For bleeding tendency, the descriptive analysis showed that one of the two comparisons identified a significant difference in favour of chewing gum. The meta-analysis, however, did not substantiate this difference. CONCLUSION Within the limitations of this systematic review, it may be concluded that the use of sugar-free chewing gum as an adjunct to toothbrushing provides a small but significant reduction in plaque scores. Chewing sugar-free gum showed no significant effect on gingivitis scores. In the absence of brushing, no effect on plaque and gingivitis scores could be established.

Abstract
OBJECTIVES The primary objective was to determine the erosive effect of expectorated saliva, following chewing acidic gum, on enamel and dentine samples, using a non-acidic gum as a negative control. Secondary objectives were to determine the effect of brushing enamel and dentine samples and the effect of individual saliva pH and buffering. DESIGN A single-centre, single-blind, placebo-controlled, two-way crossover study. SETTING A clinical trial, involving healthy participants, undertaken at Bristol Dental School and Hospital. METHODS Eight healthy participants expectorated saliva onto prepared enamel and dentine samples while chewing gum (strawberry flavoured acidic gum [active] or peppermint flavoured non-acidic gum [control]). Half of the enamel and dentine samples were brushed before measurement by contact profilometry. MAIN OUTCOME MEASURES Mean enamel and dentine erosion, with and without brushing and the relationship to salivary buffering.Results At 10 days, mean depth of surface loss from dentine samples (95% CI), following chewing of acid-containing gum and subsequent brushing, was -11.34 μm (2.22 μm) and from un-brushed dentine samples was -11.02 μm (1.71 μm). No significant erosion was noted for other groups. CONCLUSIONS Frequent chewers of acid-containing gums are susceptible to dentine erosion even in the presence of good salivary buffering. Enamel erosion was insignificant within the time constraints of the present study but warrants further investigation.

Abstract
OBJECTIVE To investigate whether gum chewing affects perceived levels of everyday stress among persons who (1) regularly chew gum or (2) do not chew gum on a regular basis. RESEARCH DESIGN AND METHODS Two Internet-based studies were conducted. Study 1 enrolled participants who chewed gum > or =4 days per week, chewed > or =11 pieces of gum per week, and chewed gum during the previous week (frequent or heavy chewers, n = 280). Study 2 enrolled participants who had chewed gum previously but did so infrequently and had not chewed during at least the 7 days before recruitment (n = 212). Both studies used a randomized, crossover design: each participant either chewed gum or abstained from chewing for a number of sequential days, then switched to the opposite behavior for the same number of days. Stress levels were assessed by means of self-reported responses to the State-Trait Anxiety Inventory (STAI) at screening and after each test sequence. RESULTS More participants (54% in study 1 [p < or = 0.10] and 57% in study 2 [p < or = 0.05]) reported that chewing gum reduced their stress level at least a little, compared with those who reported no effect on or an increase in stress. In both studies, mean STAI state scores increased significantly after the abstaining period, indicating an increase in the perceived level of stress, and decreased significantly after the gum-chewing period. Particular stress-specific emotions (e.g., not feeling relaxed, feeling tense) were reported to have significantly increased when participants abstained from chewing gum and to have decreased when they chewed. More severe levels of stress (e.g., being upset or frightened) were not affected by chewing or abstaining from chewing gum. The studies had several potential limitations, including self-reporting, a large initial recruitment, and the need for habit alteration. CONCLUSIONS The findings point to a relationship between decreased stress and gum chewing and suggest chewing gum may help reduce perceived levels of everyday stress.

Abstract
UNLABELLED Sugar-free chewing gum has been claimed to be a useful means of reducing dental plaque accumulation. The incorporation of additives, such as enzymes, abrasives and divalent metal ions, into gum formulations might improve their antiplaque activity, particularly at the buccal and lingual surfaces of the teeth. OBJECTIVES The aim of this study was to investigate the plaque inhibitory effects of three sugar-free chewing gums each containing lactoperoxidase (LP), micro granules of silicon dioxide (SD), and zinc gluconate (ZG). METHODS The study was an observer-masked, randomized cross-over design balanced for carryover effects, involving 12 healthy volunteers in a 4-day plaque regrowth model. An additive-free (AF) gum served as positive/negative control for occlusal and smooth surfaces, respectively. On day 1, subjects received professional prophylaxis, suspended oral hygiene measures, and commenced chewing their allocated product. Gum chewing was one piece chewed for 30min 4 times a day. On day 5, subjects were scored for disclosed plaque. RESULTS There were no significant differences in antiplaque activity of the gums tested, neither for the smooth nor for the occlusal surfaces (P=0.447 and P=0.418, respectively). Similar results were obtained for the anterior and posterior sites of smooth surfaces (P>0.05), and for the lower and upper sites of occlusal surfaces (P=0.451 and P=0.53, respectively). CONCLUSIONS These findings suggest that the chewing gums containing LP, SD and ZG would provide no plaque inhibitory effects on smooth surfaces. The gums containing these additives, therefore, should not be recommended as adjuncts to mechanical oral hygiene.

Abstract
BACKGROUND AND AIM Chewing gum has the potential to provide oral health benefits including plaque control. The aim of this study was to determine the effects of chewing sugar free gum on plaque regrowth at buccal, lingual and occlusal surfaces of teeth. METHOD AND MATERIALS 11 healthy and dentally-fit dental hygiene students participated in this randomised, single-blind crossover 4-day plaque regrowth study. From a zero plaque score on day 1, subjects suspended oral hygiene measures and either chewed gum or did not chew gum over 4 days. Gum chewing was one piece chewed for 30 min 4 x per day. On day 4, subjects were scored for plaque after disclosing from buccal, lingual and unrestored occlusal surfaces. RESULTS There was no significant difference in smooth surface plaque scores between the treatments but significantly less plaque accumulated (44%) at occlusal surfaces during gum chewing compared to no gum chewing. CONCLUSION Chewing gum can reduce plaque accumulation at sites of predilection for caries but has little or no effect at sites of predilection for gingivitis.

Abstract
Although the prevalence of dental caries has decreased gradually in the past three decades in the Australian population, dental caries remains the primary reason for tooth loss in Australia. At the community level, total health expenditure on the treatment of dental caries (and its consequences) is substantial. Accordingly, caries prevention is an important focus at both the individual and community levels. This paper outlines the principles upon which modern caries prevention is based and stresses the importance of manipulating the oral environment (in terms of salivary parameters, ions, pH and the oral flora) as a major strategy for effective long-term caries prevention. Practical advice is provided on the correct home use of preventive agents, including chewing gums, chlorhexidine, fluorides, bicarbonate rinses and phosphopeptides.

Abstract
The world market for chewing gum is estimated to be 560,000 tons per year, representing approximately US $5 billion. Some 374 billion pieces of chewing gum are sold worldwide every year, representing 187 billion hours of gum-chewing if each piece of gum is chewed for 30 minutes. Chewing gum can thus be expected to have an influence on oral health. The labeling of sugar-substituted chewing gum as "safe for teeth" or "tooth-friendly" has been proven beneficial to the informed consumer. Such claims are allowed for products having been shown in vivo not to depress plaque pH below 5.7, neither during nor for 30 minutes after the consumption. However, various chewing gum manufacturers have recently begun to make distinct health promotion claims, suggesting, e.g., reparative action or substitution for mechanical hygiene. The aim of this critical review--covering the effects of the physical properties of chewing gum and those of different ingredients both of conventional and of functional chewing gum--is to provide a set of guidelines for the interpretation of such claims and to assist oral health care professionals in counseling patients.

Abstract
A clinical study was carried out to determine the acceptability of a sugar-free, low-tack chewing gum by orthodontic patients undergoing fixed appliance treatment. Twenty-five orthodontic and 25 non-orthodontic control subjects were questioned on their preference between regular-tack and low-tack chewing gum. The orthodontic subjects showed a strong preference for the low-tack gum compared with the regular-tack gum. It was concluded that low-tack, sugar-free chewing gum can be used by orthodontic patients to increase saliva flow, with the potential to promote remineralization and help reduce white spot lesion formation related to fixed orthodontic appliances. This gum should also be of value in patients being treated for xerostomia who are wearing a partial denture.

Abstract
Chlorhexidine is a well-established agent used for the control of supragingival plaque but is not without disadvantages, such as tooth staining, which limits its clinical applications to short-term use. This clinical trial studied the clinical effectiveness and stain-forming potential of chlorhexidine in a chewing gum base. Subjects (151) were screened for baseline plaque and gingival indices before receiving a dental prophylaxis and randomized into 3 treatment groups: group 1 chewed 2 pieces of chlorhexidine diacetate gum for 10 min 2x a day (total daily chlorhexidine = 20 mg), group 2 chewed 2 pieces of placebo gum for 10 min 2x a day and group 3 rinsed with 10 ml of 0.2% chlorhexidine gluconate mouthwash for 1 min 2x per day (total daily chlorhexidine = 40 mg). Plaque, gingivitis and stain evaluations were made at 4 and 8 weeks. Plaque and bleeding scores were significantly lower at 4 and 8 weeks in the chlorhexidine gum group compared to the placebo gum group and similar at 8 weeks to the rinse group. Stain intensity at week 8 was significantly less for the chlorhexidine gum than rinse. The staining measured by extent was also less with the chlorhexidine gum than the rinse, but the difference was not significant at week 4. At week 8, stain extent was significantly lower in the chlorhexidine gum group than chlorhexidine rinse. In conclusion, the results of this study demonstrate that this chlorhexidine chewing gum used with normal tooth cleaning provides similar adjunctive benefits to oral hygiene and gingival health as a 0.2% chlorhexidine rinse.

Abstract
The aim of this study was to determine the plaque extension rate following both a sucrose restricted and a sucrose supplemented diet. Eighteen female students, 19-32 yr of age, volunteered to participate in the study. The experiment comprised two periods, with each consisting of five consecutive days of no oral hygiene. The diet during one experimental period was composed of typical Swedish food with no addition of sucrose. The diet during the other experimental period was identical except for the daily addition of 100 g sucrose. Plaque was assessed after 24 h, 72 h, and 120 h with the aid of photographs which were evaluated photogrammetrically. The results showed a mean plaque extension rate of 0.32% per hour during the period with no additional sucrose and 0.36% per hour with sucrose addition. The difference was not statistically significant. The results suggest that moderate amounts of sucrose added to normal diet do not influence the plaque extension rate.

Abstract
Synopsis Dental plaque accumulates on hard non-shedding surfaces such as teeth, dentures and orthodontic appliances. This accumulation is facilitated by the absence of adequate oral hygiene procedures. The term 'plaque' describes a mass of microorganisms embedded in an organic matrix of host and microbial origin. In addition to the aesthetic desirability of 'clean teeth, healthy gums and fresh breath' associated with the absence of plaque, obvious consequences of the presence of plaque include tooth decay (dental caries), gingivitis and periodontal (gum) disease and denture associated problems. Thus the prevention of plaque formation, the reduction of plaque accumulation and the effective removal of plaque are considerations of the cosmetic and health professions alike. There are many oral hygiene products available to the general public - toothpastes, mouthwashes, denture cleaners, and, more recently, chewing gums and novel mouthwashes. Several of these products have antimicrobial components. This paper reviews the microbiology of plaque and plaque associated problems, and surveys the type of products currently available for maintenance of good oral hygiene. Potential areas for future development are also explored.

Abstract
The aim of the present investigation was to evaluate the relationship of overjet to periodontal status. Detailed examinations of occlusal and periodontal characteristics were completed on 914 12-year-old children. Plaque indices, bleeding indices, and anterior overjet were recorded for each incisor tooth. There was a significant association between mean plaque scores and the extremes of overjet measurement, suggesting that tooth cleaning is more difficult in these cases. Also, it was apparent that for right-handed children, the plaque and gingivitis scores were lower on the left side of the mouth.

Abstract
Numerous factors may affect the distribution of plaque and gingivitis in any individuals mouth. Of considerable importance must be the oral hygiene habits of each person, which will be influenced by compliance and dexterity with tooth cleaning methods. The pattern of gingivitis seen at a young age may, with time, reflect the eventual distribution of attachment loss. This in part, could explain the considerable variation in chronic periodontal disease seen between individuals and at different sites within the same mouth. This study reports the baseline data for the distribution of plaque and gingivitis in 1105, 11-12-year-old children in South Wales. The children were selected by disproportionate stratified random sampling and examined by a multidisciplinary group with the long-term aim of evaluating the importance of malocclusion to dental health and psychosocial variables. Toothbrushing frequency had a very low but significant correlation with the distribution of plaque and gingivitis, accounting therefore for only a small % of the variance in the group. For the total group and right-handed toothbrushers, buccal plaque and gingivitis was significantly increased on right contralateral teeth. No specific pattern for plaque and gingivitis distribution by side was seen for 100 left-handed toothbrushers. Plaque and gingivitis also showed significant differences dependent upon arch, tooth number, and surface. The population is being followed at 4-year intervals to monitor the pattern of periodontal disease with time and correlate changes with these baseline findings.
