An Overview of Different Interdental Cleaning Aids and Their Effectiveness

The effectiveness of water jet flossing and interdental flossing for oral hygiene in orthodontic patients with fixed appliances: a randomized clinical trial

BACKGROUND

Orthodontic treatment presents challenges with plaque accumulation around brackets, archwires, and elastics, leading to retained plaque and gingival inflammation. Conventional toothbrushing may not be enough, requiring additional oral hygiene aids like interproximal brushes, dental flosses, and water flossers. Limited research exists on comparing water flossing and interdental flossing in orthodontic patients. Therefore, this study aims to assess their effectiveness in maintaining oral hygiene during active orthodontic treatment.

METHODS

A single-blind, randomized, parallel clinical study recruited orthodontic patients with full-mouth brackets and archwires. Thirty participants were randomly assigned to either water jet flossing or interdental flossing groups. All participants were instructed to brush twice daily with a provided toothbrush and toothpaste and use the assigned intervention once daily at night. Clinical measures, including the Gingival Bleeding Index (BI), Plaque Index (PI), and Gingival Index (GI), were recorded at baseline and day 14. Descriptive statistics and statistical tests were performed using SPSS software.

RESULTS

The water jet flossing group demonstrated a slightly higher, albeit non-significant, benefit in plaque removal (median difference of 6.79%%, P = 0.279) and bleeding reduction (median difference of 5.21%%, P = 0.172) compared to the interdental flossing group after two weeks. Both groups showed significant reductions in gingival bleeding index and plaque index from baseline to the 2-week follow-up. The interdental flossing group had median mean percentage differences of 16.13%% (plaque index) and 23.57% (gingival bleeding index), while the water jet flossing group had median percentage differences of 21.87% (plaque index) and 32.29% (gingival bleeding index). No significant changes in gingival index grades were observed in either group.

CONCLUSION

Both water jet flossing and interdental flossing were effective in reducing plaque accumulation and gingival bleeding among orthodontic patients. While no significant differences were found between the two methods, water jet flossing showed a potential advantage. Further research is needed to validate its effectiveness, assess long-term impact, and understand its benefits for orthodontic patients.

A Comparative Review of Water Flossers in Periodontal Therapy

This study investigated the efficacy of water flossers (WFs), devices used to irrigate the interdental and subgingival areas, compared to other interdental care methods, in the management of periodontal disease. A computerized PubMed search was conducted by the author, encompassing the years 1962 to 2023. The year 1962 was selected due to it being the introduction of the first WF. Keywords included "oral irrigator", "efficacy," and "water flossers." The review provided a broad comparative assessment of WFs, rather than an exhaustive detailed article review. We discussed the history and evolution of commercially available WFs and introduced a novel classification system. The research also evaluated the performance of WFs in comparison to traditional and novel interdental care methods, focusing on crucial clinical parameters such as plaque removal efficiency and reduction in gingival inflammation. The results of the study reveal that WFs appear to be superior in the management of periodontal disease and have demonstrated effectiveness in a variety of indices. However, it's worth noting that the author did not statistically analyze any of the data. We identified gaps in the literature and found opportunities for further clinical studies. These findings hold implications for optimal periodontal disease prevention and management, addressing the evolving landscape of oral care practices.

Comparing the effectiveness of water flosser and dental floss in plaque reduction among adults: A systematic review

Introduction

Interdental aids such as dental floss and water flossers have been found to be effective in removing interdental plaque. This systematic review aimed to compare the available data on the efficacy of dental floss and water flossers in plaque removal among adults.

Materials and Methods

Five databases: PubMed, Scopus, Cochrane, ScienceDirect, Lilac, and Google Scholar were searched from January 1, 2002, to October 31, 2022, to obtain the relevant articles. Based on the search strategy, the titles of the studies were screened independently by two reviewers. Randomized controlled trials were included in the review, in which the study participants were given either dental floss or water flosser. Reduction in plaque scores was the outcome that was assessed. Seven articles met the eligibility criteria and were further processed for qualitative analysis.

Results

The majority of the studies favored water flossers over dental floss in plaque reduction. Water flosser was also found to be effective in removing plaque from inaccessible interproximal areas of the tooth surfaces as compared to dental floss.

Conclusion

Based on the scope of this review, results suggest that water flossers can be used as an effective alternative to dental floss in patients with manual dexterity, patients undergoing orthodontic treatment, and patients with dental prostheses.

The Efficacy and Safety of Oral Irrigator on the Control of Dental Plaque and Gingivitis: A Randomized, Single-Blind, Parallel-Group Clinical Trial

BACKGROUND

To evaluate the efficacy and safety of oral irrigator (OI) in controlling dental plaque and gingivitis.

METHODS

Ninety participants diagnosed with gingivitis were randomly assigned to two groups, given a toothbrush combined with OI (WaterPik®) (test) or a toothbrush alone (control). The Turesky-Modified Quigley-Hein Plaque Index (T-QH), Modified Gingival Index (MGI), Bleeding Index (BI), and percentage of sites with bleeding on probing (BOP%) were evaluated at baseline, 4 weeks, 8 weeks, and 12 weeks. The full analysis set (FAS) and per-protocol set (PPS) were analyzed. Adverse events were recorded through electronic diaries and examinations.

RESULTS

Of the 90 participants, the efficacy was assessed in the following numbers (FAS/PPS): test (45/33) and control (43/38). Compared with the control, MGI, BI, and BOP% were significantly lower in the test group after 4 weeks (4 weeks: p = 0.017, p = 0.001, and p = 0.001, respectively; 8 weeks and 12 weeks: p < 0.001 for all, FAS); T-QH was significantly lower after 8 weeks (8 weeks: p = 0.033; 12 weeks: p = 0.006, FAS). Transient gingival bleeding may be associated with OI. Self-reported pain and dentin hypersensitivity symptoms were similar between groups.

CONCLUSIONS

As adjuncts to toothbrushing, OI demonstrated significantly better efficacy in controlling dental plaque and gingival inflammation with no substantial safety hazards.

Effect of interproximal home oral hygiene on clinical parameters and inflammatory biomarkers in patients receiving periodontal maintenance

BACKGROUND

The purpose of this 6-week, single-blinded, randomized clinical trial was to determine if the use of an interproximal brush, with or without a tracking device, is more effective than an oral irrigator in improving interproximal probing depth (PD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), bleeding on probing (BOP), and inflammatory markers.

METHODS

Seventy-six patients with Stages III-IV, Grade B periodontitis and a 5-7 mm posterior interproximal PD with BOP were randomized: (1) interproximal brush alone (IB; n = 26), (2) interproximal brush with tracking device (TD; n = 23), (3) oral irrigator (OI; n = 27). Participants used devices once daily for 6 weeks. Clinical measurements (PD, CAL, PI, BOP, GI) and gingival crevicular fluid (GCF) samples were collected at baseline and 6 weeks.

RESULTS

All groups showed a significant reduction in PD and CAL (≥1.1 mm, p < 0.0001) and improvement in BOP (≥56%, p < 0.0001) and GI (≥82%, p < 0.001) at the experimental site with no differences among groups. The IB and IB+TD groups showed a significant reduction in PI (≥0.9, p ≤ 0.01). Interleukin (IL)-1β was reduced in all groups (p = 0.006), but IB+TB more than OI (p ≤ 0.05). IL-10 was reduced among all groups (p = 0.01), while interferon-gamma significantly increased (p = 0.01) in all groups.

CONCLUSIONS

IB and OI improved clinical parameters of PD and CAL and reduced inflammatory markers (BOP, GI, GCF IL-1β). IB had better interproximal plaque reduction. Tracking did not significantly improve clinical parameters compared with the IB and OI groups, suggesting future modifications are needed.

Efficacy of power-driven interdental cleaning tools: A systematic review and meta-analysis

OBJECTIVES

To summarize the available evidence on the efficacy of power-driven interdental cleaning tools (PDICTs) as an adjunct to tooth brushing compared to tooth brushing alone or tooth brushing combined with any other non-PDICT in terms of interproximal plaque and gingival bleeding reduction in gingivitis patients.

MATERIAL AND METHODS

A systematic literature search was performed in three databases until March 20, 2022 with the following main eligibility criteria: (1) randomized controlled clinical trials (RCTs) with (2) at least 28 days of follow-up in (3) gingivitis patients. Interproximal plaque and bleeding values were defined as the primary outcome variables and used for pair-wise meta-analyses.

RESULTS

Sixteen RCTs were identified including data from 1258 participants at the final evaluation. Eight studies each investigated the effect of either a liquid-based or mechanical PDICT; one of these studies tested additionally a combined liquid-based and mechanical PDICT. Tooth brushing combined with a liquid-based PDICT compared to tooth brushing alone did not result in better interproximal plaque values but in significantly lower interproximal bleeding values. Tooth brushing combined with either a liquid-based PDICT or with a mechanical PDICT compared to tooth brushing and flossing achieved comparable interproximal plaque and bleeding values. The majority of studies reporting on patient compliance/preference favored the use of a PDICT, and except for a single study, which was reporting soft tissue trauma in two subjects from improper use of a mechanical PDICT, none of the studies reported adverse events.

CONCLUSIONS

Daily use of PDICT as an adjunct to tooth brushing significantly reduces interproximal bleeding. This effect appears comparable to that of flossing, while PDICT may achieve higher patient acceptance/compliance.

The Oral Microbiota in Valvular Heart Disease: Current Knowledge and Future Directions

Oral microbiota formation begins from birth, and everything from genetic components to the environment, alongside the host's behavior (such as diet, smoking, oral hygiene, and even physical activity), contributes to oral microbiota structure. Even though recent studies have focused on the gut microbiota's role in systemic diseases, the oral microbiome represents the second largest community of microorganisms, making it a new promising therapeutic target. Periodontitis and dental caries are considered the two main consequences of oral bacterial imbalance. Studies have shown that oral dysbiosis effects are not limited locally. Due to technological advancement, research identified oral bacterial species in heart valves. This evidence links oral dysbiosis with the development of valvular heart disease (VHD). This review focuses on describing the mechanism behind prolonged local inflammation and dysbiosis, that can induce bacteriemia by direct or immune-mediated mechanisms and finally VHD. Additionally, we highlight emerging therapies based on controlling oral dysbiosis, periodontal disease, and inflammation with immunological and systemic effects, that exert beneficial effects in VHD management.

The influence of artificial saliva on the cleaning force of interdental rubber picks: an in-vitro comparison

BACKGROUND

The familiar aids for interdental cleaning such as dental floss or interdental brushes (IDB) are often associated with difficult handling or an increased potential for trauma. Interdental picks (IRP), which have no metal core and silicone flaps instead of nylon brushes, offer the alternative. However, in-vitro studies found a lower cleaning effectiveness combined with higher forces for cleaning compared with conventional IDBs. The aim of this in-vitro study was to measure the experimental cleaning forces (ECF) using IRP with versus without an artificial saliva (AS; GUM Hydral, Sunstar Suisse SA, Etoy, Switzerland).

METHODS

The test set-up was developed to investigate the cleaning of 3D-printed interdental area (IDR) mimicking human teeth (Form 2, Formlabs Sommerville, MA, USA) under standardized conditions. Three different morphologies (isosceles triangle, convex, concave) and three different sizes (1.0 mm,1.1 mm,1.3 mm) were used. Two different IRPs (GUM Soft-picks Advanced: SPA versus GUM Soft-picks Advanced Plus: SPA+, Sunstar Suisse SA, Etoy, Switzerland) in three sizes (small, regular, large), were used with versus without AS. ECF during ten cleaning cycles were recorded by a load cell [N].

RESULTS

Using AS leaded to significant lower values for ECF than without (1.04 ± 0.66 N versus 1.97 ± 1.01 N, p < 0.001). In general, a lower ECF was recorded for convex IDR compared to isosceles triangle and concave morphologies (p < 0.001) as well as for gap sizes of 1.3 mm compared to the smaller sizes (p < 0.001). For SPA+ we found significantly higher force values than for SPA (1.67 ± 0.93 N versus 1.31 ± 0.97 N, p < 0.001) independent of the use of AS.

CONCLUSION

Within the study´s in-vitro limitations, we found AS reduced ECF of IRPs by half and allowed using larger diameters interdentally, which could be associated with (1) a higher cleaning effectiveness and (2) a higher acceptance e.g. of patients with dry mouth. This has to be confirmed by further clinical investigations.

Evaluating Soft Tissue Healing after Implant Placement Using Two Different Mouthwashes (Myrrh and Chlorhexidine Gluconate): A Randomized Control Trial

The use of mouthwash is often recommended by dental experts for dental healing. A double-blind, randomized clinical study was conducted to evaluate the efficacy of two mouthwashes (myrrh and chlorhexidine gluconate) on postoperative pain and their effects on tissues after dental implant placement in 35 patients (18 in the myrrh group and 17 in the chlorhexidine gluconate group). Soft tissue healing was evaluated in terms of wound closure, soft tissue swelling, and the color of the gingiva at 1 week postoperative. To decrease the chances for error, only the participants who did not show preoperative symptoms of infection and those who committed to practicing better oral hygiene were included in the study. The samples were evaluated for the infiltration of inflammatory cells (using inflammatory extent and inflammatory cellularity grades), maturation of collagen (osteoblast activity), and arrangement of cells (for detecting the remodeling phase). A questionnaire pertaining to mouthwash satisfaction, the duration of postoperative pain after the procedure, the time of stoppage of bleeding at the surgical site, and any sensitivity at the surgical site was given to the patients. The Chi-square test and Mann–Whitney U-test were used to analyze the data. The difference in postoperative surgical swelling, pain, bleeding, and redness in the patients was not statistically significant between the myrrh and chlorhexidine gluconate mouthwash groups. However, in the acute phase, the myrrh mouthwash showed a positive impact on the process of wound healing after implant placement. The small sample size and inability to compare wound healing in different anatomical areas of the oral cavity were the study limitations.

Efficacy of an interdental brush in cleaning artificial plaque on a 3D-printed model base

BACKGROUND

Among interdental cleaning aids (ICAs), interdental brushes (IDBs) are in the spotlight because they can effectively remove plaque from interdental surfaces. Guidance on the correct use of ICAs, such as IDBs, is required to prevent dental plaque accumulation. Since it is impossible to confirm the interdental proximal surface unless extracted, it is difficult to conduct quantitative experiments. This study presented an efficient way to evaluate IDBs by realizing dental structures and embrasures using a Dental computer-aided design (CAD) software and a 3D printer.

METHODS

Two different sizes of embrasure (0.7 and 1.2 mm) crown models were prepared with CAD software and a 3D printer. To evaluate the cleaning efficacy of IDBs of each size (0.6, 0.7, 0.8, 1.0, 1.2, and 1.5 mm diameters), the 9th cycle of brush move was performed where artificial plaque was spread and a digital camera was used to record the process. The pixels and percentage of cleaning from the recorded digital images were analyzed.

RESULTS

The plateau was formed after the 5th brushing cycle under all conditions-after the 5th cycle, the cleaning efficacy of the two crown models was 69.3-86.4% and 49.8-75.4%. In these results, the optimal diameters for the IDB were 1.2 and 1.5 mm for embrasure sizes of 0.7 and 1.2 mm, respectively. Moreover, the cleaning efficacy was the highest at 86.4% and 75.4% after the 9th cycle.

CONCLUSIONS

The 3D-printed model base for the human oral embrasure structure is an adequate model to test artificial plaque removal using IDB. The use of IDBs for more than five cycles does not support the conventional idea that a greater number of IDB brushing moves is more effective in a statistically substantial manner.

Status Quo in Mechanical Plaque Control Then and Now: A Review

There are various kinds of dental diseases, of which dental caries and disease of periodontal origin are the most common. A very strong connection has been proven between oral inflammation and general health of an individual. Dental Biofilm is the main cause for gingivitis and periodontitis. Dental plaque may also be referred to as microbial plaque that consists of highly organized structures of different microbiotas attached to the hard tooth structure, which may be bound by salivary glycoproteins. Plaque control is a term that refers to removal of already formed or the control of formation of this microbial biofilm. There have been various methods practiced for plaque control; they are broadly classified into mechanical methods and chemical plaque control methods. Mechanical plaque control further includes many other methods such as manual toothbrushes and smart toothbrushes, which includes power-driven toothbrushes, sonic and ultrasonic toothbrushes, solar-powered toothbrushes (ionic toothbrushes), disposable toothbrushes, and laser toothbrushes; this also includes interdental cleaning aids. Continuous advancements with the integration of technology have been made in the field of mechanical plaque control to improve its quality.

Adjunctive Use of Active Compounds such as Chlorhexidine in the Nonsurgical Treatment of Peri-Implant Mucositis for Oral Health: A Systematic Review and Meta-Analysis

Background. Peri-implant mucositis (PiM) is characterized as a reversible inflammatory change of the peri-implant soft tissues without alveolar bone loss or continuing marginal bone loss. Without proper control of PiM, the reversible inflammation may advance to peri-implantitis (PI). Mechanical debridement (MD) by the implant surface is the most common and conventional nonsurgical approach to treat PiM but with limitations in complete resolution of diseases. For more than a decade, chlorhexidine (CHX) and active compounds has been investigated in the treatment of PiM. Therefore, the aim of this systematic review and meta-analysis was to evaluate the efficacy of CHX treatment in combination with MD versus MD alone or MD+placebo in patients with PiM on their oral health problems. Methods. A search using electronic databases (Ovid MEDLINE, EMBASE, Science Direct databases, and Cochrane Central Register of Controlled Trials) and a manual search up to May 2022 were performed independently by 2 reviewers and included eligible randomized controlled trials (RCTs) comparing MD+CHX versus MD alone or MD+placebo. The assessment of quality for all the selected RCTs was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions. Disease resolution of PiM (absence of BOP), IPPD reduction, IBOP% reduction, and PI% reduction after treatment as primary outcomes were selected as the primary outcomes. Weighted mean differences (WMD) and 95% confidence interval (CI) were for continuous outcomes, and odds ratio (OR) and 95% CI was for dichotomous outcomes using random effect models. This review is registered on the PROSPERO database (CRD42020221989). Results. After independent screening, nine eligible studies were included in this systematic review and meta-analysis. Meta-analysis showed OR of disease resolution between test and control groups amounted to 1.41 (95% CI (0.43, 4.65), $P=0.57$ , $I^2=65\%$ ) not favoring adjunctive CHX treatment over MD alone. Through subgroup analysis, the results indicated that oral irrigation of CHX may have more benefits on the resolution of PiM. Similarly, CHX did not significantly improve IPPD reduction at both short-, medium-, and long-term follow-up. Only a short-term effect has been observed at IBOP% reduction ( $\text{WMD}=13.88$ , 95% CI (10.94, 16.81), $P<0.00001$ , $I^2=9\%$ ), IPI reduction ( $\text{WMD}=0.12$ , 95% CI (0.09, 0.14), $P<0.00001$ , $I^2=0\%$ ), and FMPPD reduction ( $\text{WMD}=0.19$  mm, 95% CI (0.03, 0.35), $P=0.02$ , $I^2=0\%$ ) with adjunctive CHX application. Conclusion. Adjunctive CHX application may have some benefits to improve the efficacy of MD in PiM treatment by reducing IBOP%, IPI, and FMPPD in short-term. But these benefits disappeared at medium- and long-term follow-up. In order to achieve better disease resolution of PiM, adjunctive CHX irrigation with MD may be suggested and has positive potential. Well-designed large clinical trials are needed in future.

Individually Modeled 3D Printed Toothbrush and Interproximal Brush Handle With Name for Patients With Limited Manual Dexterity

Maintenance of proper oral hygiene is a cumbersome task when hand and finger movement is restricted. The customized handle allows better grip on the toothbrush, making it easier to brush teeth or dentures. This increases self-esteem by reducing their dependency on others. This article describes a method of fabricating a 3D printed two-in-one customized handle for a patient with limited manual dexterity. The 3D printed handle is simple and requires less fabrication time than other methods. The customized handle is strong, durable, and resistant to water absorption. It also allows reuse with a new brush design, thus saving additional time and cost. In addition, using a customized toothbrush handle is more effective in oral plaque control than a standard toothbrush.

A Randomized Controlled Trial for Evaluation of the Effectiveness of Oral Irrigator and Interdental Floss for Plaque Control in Children with Visual Impairment

Aim

To evaluate the effectiveness of oral irrigator and interdental floss as adjuncts to manual tooth brushing in 8-16 years old children with visual impairment.

Materials and methods

A three-arm, parallel-group randomized controlled trial with blinded outcome assessment was carried out with the inclusion of 90 institutionalized children with visual impairment of age 8-16 years. They were equally allocated to three groups: group I: tooth brushing along with interdental flossing, group II: brushing along with a powered oral irrigator, and group III: brushing alone (control). Baseline oral hygiene index-simplified (OHI-S), gingival index (GI), and plaque index (PI) scores were recorded for all the samples and compared with post-intervention scores at 14 and 28 days intervals. Repeated measures of analysis of variance (ANOVA), one-way ANOVA, and post hoc Tukey tests were used for statistical analysis.

Results

At 28 days interval, children in group II showed a highly statistically significant reduction in OHI-S (0.46; p = 0.0001), PI (0.16; p = 0.0001), and GI (0.24; p = 0.0001) scores compared to control group. They also showed a significant reduction in OHI-S (0.25; p = 0.018), PI (0.15; p = 0.011), and GI (0.15; p = 0.0001) scores compared to group I. There is no significant reduction in the scores of children of group I compared to control group except for the GI score (0.08; p = 0.02).

Conclusion

Oral hygiene maintenance using oral irrigator along with brushing was found to be more effective in visually challenged children. Interdental flossing, along with brushing and brushing alone was found to be less effective.

Clinical significance

This study underlines the fact that comprehensive oral hygiene care should include interdental cleaning aids for effective plaque control to prevent dental diseases in children with visual impairment. Since these children have less manual dexterity to perform good oral hygiene practices, electrically driven interdental cleaning aids like oral irrigator may help them to overcome the problem.

Early Response and Clinical Efficacy of a Mouthwash Containing Chlorhexidine, Anti Discoloration System, Polyvinylpyrrolidone/Vinyl Acetate and Sodium DNA in Periodontitis Model: A Triple-Blind Randomized Controlled Clinical Trial

Polyvinylpyrrolidone/vinyl acetate (PVP/VA) is a molecule with increased adhesion capacity, and can be associated in the bacterial plaque control with sodium DNA, a natural anti-aging molecule able to improve gingival trophism. The aim of the study is to test at two weeks the antimicrobial and antiplaque properties, subjects affected by chronic periodontitis, showed by a mouthwash containing Chlorhexidine (CHX) 0.2% with Anti Discoloration System (ADS), PVP-VA, and Sodium DNA in comparison with a placebo mouthwash. A single center randomized controlled trial was conducted on a total of fifty-four (54) subjects. In the test Group (n = 27) patients were treated by a 0.2% Chlorhexidine (CHX) mouthwash with ADS, PVP-VA, and Sodium DNA, while a placebo mouthwash was used in the control Group (B). The full mouth plaque score (FMPS), full mouth bleeding score (FMBS), and gingival index (GI) were assessed at baseline, and at 1 and 2 weeks after treatment. FMPS score recorded at baseline (V2) was 52.7 ± 9.2 in the Group Test and 58.2 ± 6.1 in the Group Control (p > 0.05). After 1 week (V3), FMPS was 13.3 ± 5.6 in the Group Test and 18.7 ± 4.3 in the Group Control (p < 0.05), while at V4 (2 weeks), FMPS was 14.2 ± 4.1 in the Group Test and 20.3 ± 5.2 in the Group Control (p < 0.05). FMBS score recorded at baseline (V2) was 46.7 ± 8.7 in the Group Test and 49.2 ± 6.2 in the Group Control (p > 0.05). After 1 week (V3), FMBS was 12.7 ± 4.2 in the test Group Test and 18.5 ± 5.9 in the control Group Control (p < 0.05), while after 2 weeks (V4), it was 13.1 ± 3.2 in the Group Test and 19.8 ± 4.9 Group Control (p < 0.05). This trial has clinically showed the efficacy of a new formulation of chlorhexidine mouthwash in reducing bacterial plaque and gingival inflammation. A significant reduction of inflammation and bleeding scores was found in periodontal patients treated by a mouthwash containing CHX 0.2% with ADS, PVP-VA, and Sodium DNA compared to those treated with a placebo mouthwash.

Darwinian Dentistry? Social Media, Smartphones and Selfie Sticks

The COVID-19 pandemic produced numerous challenges for clinical dentistry which necessitated adaptation and innovation. This article will illustrate the use of selfie stick devices and ring lights for dental care practitioners to create customised 'selfie' videos of them using very effective cleaning devices on the patient's own smartphone. Because these short, engaging videos are now readily available to the patient at their home it reminds them which brushes to use, where and how. Patients are empowered by these videos which put them at the centre, reinforcing the key preventive message that they can improve and maintain their oral health by introducing effective oral hygiene behaviours. The many advantages, both for patients and for their practice teams, will be discussed in detail.

Convergence of Biofilm Formation and Antibiotic Resistance in Acinetobacter baumannii Infection

Acinetobacter baumannii (A. baumannii) is a leading cause of nosocomial infections as this pathogen has certain attributes that facilitate the subversion of natural defenses of the human body. A. baumannii acquires antibiotic resistance determinants easily and can thrive on both biotic and abiotic surfaces. Different resistance mechanisms or determinants, both transmissible and non-transmissible, have aided in this victory over antibiotics. In addition, the propensity to form biofilms (communities of organism attached to a surface) allows the organism to persist in hospitals on various medical surfaces (cardiac valves, artificial joints, catheters, endotracheal tubes, and ventilators) and also evade antibiotics simply by shielding the bacteria and increasing its ability to acquire foreign genetic material through lateral gene transfer. The biofilm formation rate in A. baumannii is higher than in other species. Recent research has shown how A. baumannii biofilm-forming capacity exerts its effect on resistance phenotypes, development of resistome, and dissemination of resistance genes within biofilms by conjugation or transformation, thereby making biofilm a hotspot for genetic exchange. Various genes control the formation of A. baumannii biofilms and a beneficial relationship between biofilm formation and "antimicrobial resistance" (AMR) exists in the organism. This review discusses these various attributes of the organism that act independently or synergistically to cause hospital infections. Evolution of AMR in A. baumannii, resistance mechanisms including both transmissible (hydrolyzing enzymes) and non-transmissible (efflux pumps and chromosomal mutations) are presented. Intrinsic factors [biofilm-associated protein, outer membrane protein A, chaperon-usher pilus, iron uptake mechanism, poly-β-(1, 6)-N-acetyl glucosamine, BfmS/BfmR two-component system, PER-1, quorum sensing] involved in biofilm production, extrinsic factors (surface property, growth temperature, growth medium) associated with the process, the impact of biofilms on high antimicrobial tolerance and regulation of the process, gene transfer within the biofilm, are elaborated. The infections associated with colonization of A. baumannii on medical devices are discussed. Each important device-related infection is dealt with and both adult and pediatric studies are separately mentioned. Furthermore, the strategies of preventing A. baumannii biofilms with antibiotic combinations, quorum sensing quenchers, natural products, efflux pump inhibitors, antimicrobial peptides, nanoparticles, and phage therapy are enumerated.

Oral Hygiene Practices and Knowledge among Adolescents Aged between 15 and 17 Years Old during Fixed Orthodontic Treatment: Multicentre Study Conducted in France

The aims of this study were to assess oral health knowledge, attitudes, and practices among orthodontic patients between the ages of 15 and 17 years old compared to adolescents without orthodontic treatment. This cross-sectional study included 392 adolescents drawn from various French teaching hospitals. A closed-ended questionnaire was used to collect data. Adolescents undergoing orthodontic treatment had a higher knowledge of oral health than adolescents without orthodontic treatment. The majority of adolescents for both groups (69%) claimed to brush their teeth twice a day. Regarding complimentary dental material, 81.9% of adolescents without orthodontic treatment never used an interdental brush and 78.8% never used dental floss. For those undergoing orthodontic treatment, 48.5% never used an interdental brush. Only 4% of adolescents without and 3% of adolescents with orthodontic treatment never consumed fizzy drinks, 4.9% and 3% never consumed sweets, and 4% and 8.4% never ate fast-food. Adolescents without treatment consumed more sodas (p = 0.048) and more fast food (p = 0.029). Adolescents had insufficient knowledge of oral health. Health education programmes should be implemented to improve adolescents’ knowledge and individual oral prophylaxis with interdental brushes.

A survey of oral health status, subjective oral symptoms and oral health behaviors among first-year dental students at a Japanese university

PURPOSE

The rapid deterioration of oral health in young adults is an alarming problem in Japan. The aim of the present study is to investigate the oral health status, subjective oral symptoms and oral health behaviors of dental students.

METHODS

Participants were 108 first-year students attending dental school in 2018-2019. Oral examinations were performed to assess dental caries indices, oral hygiene status, gingival bleeding on probing (BOP) and pocket depth. A self-administered questionnaire was used to assess subjective oral symptoms and oral health behaviors.

RESULTS

The prevalence of decayed teeth (DT) and gingivitis (BOP ≥ 10%) were 43.5% and 50.0%, respectively. Having DT and gingivitis were significantly associated with poorer oral hygiene. No association was observed between DT and subjective symptoms. Having gingivitis was significantly associated with xerostomia, mouth-breathing and less use of interdental cleaning tools. Multiple logistic regression analysis for gingivitis yielded an odds ratio of 1.41 (95% confidence interval: 1.19-1.67) for plaque score, and 2.75 (1.27-5.98) for xerostomia.

CONCLUSION

Since a relatively high ratio of students had DT and gingivitis without clear subjective symptoms, they require regular dental visits for early treatment and oral hygiene maintenance from the start of their time at university.

Characterizing the Content Related to Oral Health Education on TikTok

Neglecting oral hygiene in adolescents negatively affects dental caries and periodontal diseases, in addition to social and emotional well-being. Thus, the TikTok platform (ByteDance, Beijing, China)as a social media could be a powerful channel to provide health-related information and educational content. This study aims to assess the quality of the TikTok videos corresponding to #oralhealtheducation. Sixty-nine videos were identified. Three oral health professionals (OHP), three health education professionals (HEP), and ten of TikTok's target audience watched and evaluated the videos from a qualitative questionnaire. OHP detected false or incorrect information in 11.6% (8/69) of the videos. At least two HEPs reported being unable to detect this type of content or whether the video met dental ethics standards in both the videos. Disagreement was observed among the professionals themselves. The evaluation indicated that TikTok's target audience was satisfied with the products viewed with an average score of >2.5, unlike the professionals, whose average score was <2.5 on a scale of 0 to 5. Users are advised to think critically and to consider the content of TikTok oral health videos with caution. The involvement of health professionals in the writing and validation of the videos could be an added value to positively respond to the needs of the adolescents.

Bitter and sweet taste perception: relationships to self-reported oral hygiene habits and oral health status in a survey of Australian adults

Background

Oral health, an essential part of general health and well-being, is influenced by multiple factors, including oral hygiene habits and dietary factors. Dietary preferences are influenced by variation in taste perceptions and threshold tasting. Polymorphisms in specific genes for sweet and bitter taste receptors and bitter taste perception have been associated with dental caries. However, taste is complex with multiple receptors, each with multiple potential polymorphisms contributing to taste perception as well as social, cultural, and environmental influences. Additionally, these association studies have been conducted in restricted cohorts (e.g., children only). Furthermore, outcomes have been limited to dental caries and studies between taste perception and oral hygiene habits have not been completed.

Methods

A cross-sectional online survey was conducted to investigate the relationships between bitter and sweet taste perception (liking and intensity of index food items), self-reported oral hygiene habits and oral health (n = 518).

Results

Higher mean intensity scores for bitter (16–21%) and sweet (< 5%-60%) were seen with higher frequencies of oral hygiene habits (brushing, use of mouthwash, chewing gum and tongue cleaning). Lower mean bitter liking scores (18–21%) were seen with higher frequencies of oral hygiene habits (brushing, mouthwash use, floss use and chewing gum). Sweet liking scores varied by reported frequency of mouthwash use and flossing only, with mixed patterns of variance. Mean bitter and sweet intensity perception scores varied with the number of dental caries ((13–20% higher in those with 3 or more caries, compared to none).

Conclusions

While there were numerous relationships identified between liking and perception of sweet and bitter and oral health outcomes, the magnitude and direction of associations varied by outcome. The direction of the associations cannot be inferred due to the cross-sectional nature of the study. The demonstrated relationships justify further future investigations, which could help better understand if taste liking and perception is impacted by oral hygiene and health, or vice versa. This could be important in understanding the causation and progression of oral health diseases or the development of novel therapeutics for oral health.

Evaluating efficacy of a novel dentifrice in reducing probing depths in Stage I and II periodontitis maintenance patients: A randomized, double-blind, positive controlled clinical trial

BACKGROUND

Compliance to periodontal maintenance therapy (PMT) is essential for long-term periodontal health. Between PMT visits, patients must maintain good oral hygiene. A dentifrice with demonstrable clinical benefits for use between PMT visits would be highly desirable. The aim of this clinical study was to investigate the effect of a novel dental gel on probing depths (PD) and inflammation when used as a home care dentifrice in Stage I and II periodontitis patients.

METHODS

This double-blind clinical study randomized 65 subjects with Stage I and II periodontitis to the novel dental gel containing 2.6% EDTA, and a commercially available anti-gingivitis dentifrice with 0.454% stannous fluoride. Primary endpoint was PD at 6 months for those sites with baseline PD ≥ 4 mm and secondary endpoints included whole mouth mean scores of modified gingival index (MGI), modified sulcus bleeding index (mSBI) and plaque index (PI). No SRP was performed at baseline.

RESULTS

Subjects using the novel dentifrice showed significant PD reductions of 1.18 mm (from 4.27 mm at baseline to 3.09 mm at 6 months) compared to 0.93 mm (from 4.23 mm at baseline to 3.30 mm at 6 months) shown for those using the positive control dentifrice. Difference between treatments at 6 months was 0.21 mm with P-value = 0.0126. Significant improvements in MGI (P = 0.0000), mSBI (P = 0.0000), and PI (P = 0.0102) were also observed in 6 months.

CONCLUSION

The novel dentifrice showed significant reductions in PD and gingival inflammation over 6 months solely as a home care dentifrice without baseline SRP in Stage I and II periodontitis maintenance patients.

Does Customized Handle Toothbrush Influence Dental Plaque Removal in Children with Down Syndrome? A Randomized Controlled Trial

The present study aimed to evaluate the effectiveness of customized handle toothbrush in dental plaque removal in children with Down syndrome in comparison to children with no special needs. A randomized clinical trial was performed on 48 children aged 6–9 years old. Participants were divided into two groups (n = 24, children with no special needs or with Down syndrome). Each group was divided into two subgroups (customized and conventional toothbrush). Plaque accumulation was evaluated using Turesky modification of the Quigley–Hein plaque index (TMQHPI) at four times (pre-brushing (T0), post-brushing at baseline (T1), 1 week (T2) and 3 weeks (T3)), and the modified gingival index (MGI) was used to evaluate the gingivitis at three times (T0, T2 and T3). Data were statistically analyzed. Plaque accumulation and gingivitis decreased significantly for all groups between T0 and T3 (p < 0.05). Both customized groups demonstrated significant lower plaque accumulation compared to conventional groups (p < 0.05) at T1, T2 and T3 and significant lower gingivitis at T3. Customizing the toothbrush handle improved child’s ability for plaque control, especially in children with Down syndrome.

Background and Objectives: Cerebral aneurysms can cause disability or death during rupture, but information on the etiology of cerebral aneurysms is currently lacking. Periodontal disease causes both systemic inflammation and local inflammation of the oral cavity. Systemic inflammation is a major cause of cerebral aneurysms. The aim of our study was to determine whether the presence of periodontal disease is related to the occurrence of unruptured cerebral aneurysms in a nationwide population-based cohort. Materials and Methods: We analyzed data on demographics, previous medical history, and laboratory test results of 209,620 participants from the Korean National Health Insurance System-Health Screening Cohort. The presence of periodontal disease and oral hygiene parameters, including the number of lost teeth, tooth brushing frequency per day, dental visits for any reason, and expert teeth scaling, were investigated. The occurrences of unruptured cerebral aneurysms (I67.1) were defined according to the International Statistical Classification of Diseases Related Health Problems-10. Results: The mean age of the participants was 53.7 ± 8.7 years, and 59.4% were male. Periodontal disease was found in 20.9% of the participants. A total of 2160 (1.0%) cases of unruptured cerebral aneurysms developed after 10.3 years of median follow up. In multivariate analysis, the presence of periodontal disease was significantly associated with an increased risk of unruptured cerebral aneurysms (hazard ratio: 1.21, 95% confidence interval: 1.09–1.34, p < 0.001). Conclusion: The presence of periodontal disease could be associated with the occurrence of unruptured cerebral aneurysms. It should be noted that when periodontal diseases are present, the risk of aneurysms is increased in the future.

Minimally Invasive Periodontology: A Treatment Philosophy and Suggested Approach

Severe periodontitis is a highly prevalent dental disease. With the advent of implant dentistry, teeth are often extracted and replaced. Periodontal surgery, where indicated, could also result in increased trauma to the patient. This literature review discusses different treatment modalities for periodontitis and proposes a treatment approach emphasizing maximum preservation of teeth while minimizing morbidity to the patient. Scientific articles were retrieved from the MEDLINE/PubMed database up to January 2021 to identify appropriate articles that addressed the objectives of this review. This was supplemented with hand searching using reference lists from relevant articles. As tooth prognostication does not have a high predictive value, a more conservative approach in extracting teeth should be abided by. This may involve repeated rounds of nonsurgical periodontal therapy, and adjuncts such as locally delivered statin gels and subantimicrobial-dose doxycycline appear to be effective. Periodontal surgery should not be carried out at an early phase in therapy as improvements in nonsurgical therapy may be observed up to 12 months from initial treatment. Periodontal surgery, where indicated, should also be minimally invasive, with periodontal regeneration being shown to be effective over 20 years of follow-up. Biomarkers provide an opportunity for early detection of disease activity and personalised treatment. Quality of life is proposed as an alternative end point to the traditional biomedical paradigm focused on the disease state and clinical outcomes. In summary, minimally invasive therapy aims to preserve health and function of the natural dentition, thus improving the quality of life for patients with periodontitis.

In vitro comparison of cleaning efficacy and force of cylindric interdental brush versus an interdental rubber pick

BACKGROUND

Interdental brushes (IDB) are according to the actual evidence the first choice for cleaning interdental areas (IDR). Their size should be chosen individually according to the IDR morphology. However, interdental rubber picks (IRP) are appreciated better by the patients and are hence becoming more and more popular but the evidence regarding their efficacy is still limited. The aim of this in vitro study was to measure the experimental cleaning efficacy (ECE) and force (ECF) during the use of interdental brushes versus newer wireless types with rubber filaments (IRP), both fitted and non-fitted for different IDR.

METHODS

The medium size of a conical IRP (regular, ISO 2) with elastomeric fingers versus four sizes (ISO 1, 2, 3, 4) of cylindric IDB with nylon filaments (all Sunstar Suisse SA, Etoy, Switzerland) were tested. Interdental tooth surfaces were reproduced by a 3D-printer (Form 2, Formlabs Sommerville, MA, USA) according to human teeth and matched to morphologically equivalent pairs (isosceles triangle, concave, convex) fitting to three different gap sizes (1.0 mm, 1.1 mm, 1.3 mm). The pre-/post brushing situations at IDR (standardized, computer aided ten cycles) were photographically recorded and quantified by digital image subtraction to calculate ECE [%]. ECF were registered with a load cell [N].

RESULTS

Overall, a higher ECE was recorded for IDB compared to IRP (58.3 ± 14.9% versus 18.4 ± 10.1%; p < 0.001). ECE significantly depended on the fitting of the IDB. ECE was significant higher in isosceles triangle compared to concave and convex IDR for both IDB and IRP (p ≤ 0.001). ECF was lower for IDB (0.6 ± 0.4N) compared to IRP (0.8 ± 0.5N; p ≤ 0.001). ECE in relation to ECF increases with smaller IDB. For IRP highest values of ECF were found in the smallest IDR.

CONCLUSIONS

Within the limitations of an in vitro study, size fitted IDB cleaned more effectively at lower forces compared to conical IRP.

Comparison between water flosser and regular floss in the efficacy of plaque removal in patients after single use

Objective

The objective was to compare water flosser and regular floss in the efficacy of plaque removal in patients after single use.

Materials and Methods

A randomized controlled clinical trial was conducted to compare the plaque removal efficacy of water flosser and regular floss. Eighty three subjects who met the inclusion criteria were recruited from dental clinic. Silness and Löe plaque index was measured for all the subjects prior to and after the intervention by an examiner who was blind to the type of aid used. The type of floss used was randomly assigned to each side of the oral cavity; unflavored waxed regular floss (oral B) used on one side, while a water flosser (Waterpik® Cordless Plus Water Flosser) was used on the other side. A trained investigator used either unflavored waxed regular floss or water flosser as assigned. Paired t-test was used to compare between the two groups.

Results

The mean plaque scores at baseline were 1.10(±0.38) and 0.94(±0.38) respectively for regular floss and water flosser. The mean plaque scores were 0.12(±0.13) and 0.12(±0.15) respectively for regular floss and water flosser. There was no statistically significant difference in the plaque scores (p = 0.58) between the groups after the use of respective interdental aids. There was a statistically significant difference in the plaque scores before and after use of interdental aids for both the groups (p < 0.001). Reduction in plaque scores for regular floss and water flosser groups was 89.09% and 87.23% respectively.

Conclusion

The results showed that water flosser was as efficient as regular floss in removing interdental plaque on single use. Water flosser could be recommended for subjects lacking manual dexterity, by care takers for better plaque control and subjects with fixed prostheses or undergoing orthodontic treatment.

Novel Approaches to Combat Medical Device-Associated BioFilms

Biofilms are aggregates formed as a protective survival state by microorganisms to adapt to the environment and can be resistant to antimicrobial agents and host immune responses due to chemical or physical diffusion barriers, modified nutrient environments, suppression of the growth rate within biofilms, and the genetic adaptation of cells within biofilms. With the widespread use of medical devices, medical device-associated biofilms continue to pose a serious threat to human health, and these biofilms have become the most important source of nosocomial infections. However, traditional antimicrobial agents cannot completely eliminate medical device-associated biofilms. New strategies for the treatment of these biofilms and targeting biofilm infections are urgently required. Several novel approaches have been developed and identified as effective and promising treatments. In this review, we briefly summarize the challenges associated with the treatment of medical device-associated biofilm infections and highlight the latest promising approaches aimed at preventing or eradicating these biofilms.

Technology for maintaining oral care after stroke: considerations for patient-centered practice

PURPOSE

Activities of daily living including oral care may be challenging after stroke. Some stroke survivors are not able to complete oral care independently and need assistance from healthcare professionals and care partners. Poor oral hygiene may impact stroke recovery and rehabilitation possibly incurring issues such as aspiration pneumonia, malnutrition, and social isolation. The objective of this paper is to outline practical ways to apply oral care technology in daily use for stroke survivors.

MATERIALS AND METHODS

We reviewed the literature on i) stroke-related impairments impacting oral care, ii) oral hygiene dental devices, and iii) technology for oral care education.

RESULTS

Oral care activities involve integrated skills in the areas of motivation, energy, planning, body movement and sensation, and mental acuity and health. Post-stroke impairments such as fatigue, hemiparesis, and mental impairments may impact oral care activities. Technology may help survivors and caregivers overcome some barriers. Three types of technologies are available for facilitating post-stroke oral care: i) non-powered tools and adaptations; ii) powered oral care tools, and; iii) electronic aids to guide oral care activities. Particular choices should maximise patient safety and autonomy while ensuring accessibility and comfort during oral care tasks.

CONCLUSION

The available device and technologies may help substantially with the accommodations needed for post-stroke oral care, improving the oral health of stroke survivors. Good oral health confers benefit to overall health and well-being and could enhance recovery and rehabilitation outcomes. Nonetheless, more research is necessary to demonstrate the feasibility and effectiveness of technology in stroke contexts.IMPLICATIONS FOR REHABILITATIONOral care may be challenging after stroke due to patient fatigue, hemiparesis, cognitive impairments, and other impaired body functions.Poor oral hygiene may impact stroke recovery and rehabilitation due to risk of aspiration pneumonia, malnutrition, and social isolation.Powered oral care tools, non-powered tools, and adaptations to non-powered tools are some of the technology available to help overcome post-stroke barriers for oral care.Computer programs and online resources for education and guidance for oral care activities may help improve recommendation uptake and compliance.

Evaluation of Plaque Removal Efficacy of Dental Floss with/without Chlorhexidine Gel Coating in Patients with Gingivitis - A Clinical and Microbological Study

BACKGROUND: Chlorhexidine has shown anti-plaque and antimicrobial effects when used as a mouthwash and appears to be effective when used as a topical antiseptic agent. AIM: The present study aimed to compare the efficacy of chlorhexidine gel coated dental floss with that of uncoated dental floss. METHODS: This parallel, single-blinded, randomized controlled clinical trial Included 30 patients with moderate to severe gingivitis. The total population was randomly divided into three groups, with ten patients in each group. Group A received dental floss with 1% chlorhexidine gel, and Group B received only dental floss, while in Group C no dental floss was provided. All thirty volunteers were provided with standard toothpaste and toothbrush. Clinical parameters such as gingival index, plaque index, and bleeding index were recorded along with supragingival plaque sample collection for microbiological culture. Subjects were recalled after 15 days and clinical and microbiological analysis was performed. All parameters were re-assessed at the follow up visit after two weeks. RESULTS: All the groups showed a significant reduction in values of plaque index, gingival index, and bleeding index, as well as the microbial counts post-enrollment in the study. A significant reduction in the bleeding indices was noticed in Group A in comparison to C (p < 0.05). CONCLUSIONS: The use of dental floss coated with 1% chlorhexidine gluconate gel was effective as an interproximal aid for patients with moderate to severe gingivitis.

New experimental setup for the measurement of cleaning efficacy and force of interdental aids in 3D-reproduced interdental areas

BACKGROUND

Interdental rubber picks (IRP) have become a frequent and convenient alternative for interdental cleaning. However, only little evidence exists supporting the effectiveness of newer designs available on the market. Therefore, a new in vitro model was evaluated to measure the experimental cleaning efficacy (ECE), as well as the force needed for insertion and during the use of IRP, with high reproducibility.

METHODS

Five different sizes of commercially marketed IRP with elastomeric fingers (IRP-F) (GUM SOFT-PICKS® Advanced, Sunstar Deutschland GmbH, Schönau, Germany) or slats (IRP-S) (TePe EasyPick™, TePe D-A-CH GmbH, Hamburg, Germany) were tested. Interdental tooth surfaces were reproduced by a 3D-printer (Form 2, Formlabs Sommerville, MA, USA) according to human teeth and matched to morphologically equivalent pairs (isosceles triangle, concave, convex) fitting to different gap sizes (1.0 mm, 1.1 mm, 1.3 mm). The pre-/post brushing situations at interdental areas (standardized cleaning, computer aided ten cycles) were photographically recorded and quantified by digital image subtraction to calculate ECE [%]. Forces were registered with a load cell [N].

RESULTS

IRP-F have to be inserted with significant higher forces of 3.2 ± 1.8 N compared to IRP-S (2.0 ± 1.6 N; p < 0.001) independent of the size and type of artificial interdental area. During cleaning process IRP-S showed significantly lower values for pushing/pulling (1.0 ± 0.8 N/0.5 ± 0.4 N) compared to IRP-F (1.6 ± 0.8 N/0.7 ± 0.3 N; p < 0.001) concomitant to significantly lower ECE (19.1 ± 9.8 vs. 21.7 ± 10.0%, p = 0.002). Highest ECE was measured with largest size of IRP-F/IRP-S independent the morphology of interdental area.

CONCLUSIONS

New interdental cleaning aids can be tested by the new experimental setup supported by 3D printing technology. Within the limitations of an in vitro study, IRP-F cleaned more effectively at higher forces compared to IRP-S.

Incorporating Oral Health Considerations for Medication Management in Care Transitions

Transitions of care involve multifaceted considerations for patients, which can pose significant challenges if factors like oral health are overlooked when evaluating medication management. This article examines how oral health factors should be considered in medication management of patients who may be at risk for hospital readmission. This article also explores successes and challenges of a pharmacy consult service integrated into a dental clinic practice, and the opportunities within that setting to improve overall patient outcomes including those related to care transitions.

The Oral Bacterial Microbiome of Interdental Surfaces in Adolescents According to Carious Risk

Adolescence is closely associated with a high risk of caries. The identification of specific bacteria in an oral microniche, the interdental space of the molars, according to carious risk can facilitate the prediction of future caries and the anticipation of the progression or stabilization of caries in adolescents. A cross-sectional clinical study according to the bacteriological criteria of interdental healthy adolescents and carious risk factors-low and high-using a real-time polymerase chain reaction technique was conducted. The presence of 26 oral pathogens from the interdental microbiota of 50 adolescents aged 15 to 17 years were qualitatively and quantitatively analyzed. Bacteria known to be cariogenic (Bifidobacterium dentium, Lactobacillus spp., Rothia dentocariosa, Streptococcus cristatus, Streptococcus mutans, Streptococcus salivarius, Streptococcus sobrinus, and Streptococcus wiggsiae) did not present differences in abundance according to carious risk. Periodontal bacteria from the red complex are positively correlated with carious risk. However, only 3 bacteria-S. sobrinus, E corrodens and T. forsythia-presented a significant increase in the highest group. Estimating the risk of caries associated with bacterial factors in interdental sites of molars in adolescents contributes to the better definition of carious risk status, periodicity and intensity of diagnostic, prevention and restorative services.
