Knowledge, attitudes and behaviours of patients regarding interdental deplaquing devices: A mixed-methods study

Self-determined use of provided powered oral hygiene devices leads to improved gingival health after 1 year: a longitudinal clinical trial

PURPOSE

Our study aimed to evaluate the long-term concordance and acceptance when using powered devices for everyday oral hygiene routine and gingival health in patients showing papillary bleeding.

PATIENTS AND METHODS

Thirty-one participants were recruited at the dental clinic of the University Hospital of Cologne, Germany, over a 6-week duration. At baseline, a standard dental check-up was performed, including oral hygiene indices and documentation of oral hygiene devices used. The study consisted of two consecutive phases: the first (motivational trial) was designed to prove the effectiveness and safety of a microdroplet device and a powered toothbrush compared to dental floss and a manual toothbrush over a period of 4 weeks. The second (observational) phase began with all participants receiving the powered oral homecare devices. Participants were able to use their oral hygiene measures of choice over an unsupervised period of 1 year. All participants were then rescheduled for a routine dental check-up, where oral hygiene indices and oral hygiene devices used were reevaluated.

RESULTS

After 1 year, 93.3% of participants stated they performed interdental cleaning on a regular basis (baseline 60.0%). The percentage using a powered toothbrush increased from 41.9% (baseline) to 90.0% after 1 year. Oral hygiene parameters had improved after both the motivational trial and observational phases compared to baseline (papillary bleeding index p = .000; Rustogi Modified Navy Plaque Index p < .05; Quigley-Hein Index p = .000).

CONCLUSION

In the long term, participants preferred using powered oral hygiene devices over the gold standard dental floss and manual toothbrush. Improved oral hygiene parameters after 1 year may indicate implementation of newly acquired oral-hygiene skills during the 4-week instruction phase.

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.

Oral Health Status, Knowledge, and Behaviours of People with Diabetes in Sydney, Australia

This study assessed self-reported oral health status, knowledge, and behaviours of people living with diabetes along with barriers and facilitators in accessing dental care. A cross sectional survey of 260 patients from four public diabetes clinics in Sydney, Australia was undertaken using a 35-item questionnaire. Data were analysed using SPSS software with descriptive and logistic regression analyses. More than half (53.1%) of respondents reported having dental problems which negatively impacted their related quality of life. Less than half (45%) had adequate oral health knowledge. Only 10.8% reported receiving any oral health information in diabetes care settings, which had higher odds of demonstrating adequate oral health knowledge (AOR, 2.60; 95% CI, 1.06-6.34). Similarly, 62.7% reported seeing a dentist in the last 12 months. Having private health insurance (AOR, 3.70; 95% CI, 1.85-7.40) had higher odds of seeing a dentist in the past 12 months. Dental costs were a major contributor to avoiding or delaying dental visit. Patients living with diabetes have unmet oral health needs particularly around the awareness of its importance and access to affordable dental services. Diabetes care providers can play a crucial role in this area by promoting oral health to their patients.

ANTI-PLAQUE AND ANTI-GINGIVITIS EFFICACY OF DIFFERENT BRISTLE STIFFNESS AND END-SHAPE TOOTHBRUSHES ON INTERPROXIMAL SURFACES: A SYSTEMATIC REVIEW WITH META-ANALYSIS

OBJECTIVE

This systematic review aimed to evaluate the efficacy of interproximal plaque scores and gingival inflammation reduction of different toothbrush bristle stiffness and end-shape.

METHODS

Randomized clinical trials evaluating the effect of different toothbrushes on interproximal plaque/gingivitis reduction, with a minimum follow-up of 1 week. MEDLINE-PubMed, Scopus and Embase were searched. Soft tapered-tip bristle toothbrushes were compared to soft end-rounded, medium (any end-shape), or hard (any end-shape) bristle toothbrushes. Two meta-analyses were performed for plaque and gingivitis reduction. For plaque index (PI) and gingival index (GI), a standard mean difference (SMD) and mean difference between baseline and 4 weeks were calculated, respectively. In all analyses, random effect models were used.

RESULTS

Nine studies were included. All included studies demonstrated statistically significant improvement, in at least one parameter, in favor of the tapered-tip bristle toothbrush compared to the end-rounded bristle toothbrush. When analyzing toothbrush stiffness, medium and hard toothbrushes presented significantly higher improvement when compared to soft toothbrushes in all parameters. In the meta-analyses, groups that used soft tapered-tip bristle toothbrushes demonstrated significant greater reductions in PI (SMD -2.64; 95% CI: -4.26 - -1.01) and in GI (MD -0.14; 95% CI: -0.18 - -0.10) when compared to soft end-rounded bristle toothbrushes.

CONCLUSION

It is concluded that, when considering interproximal surfaces, better results may be expected for tapered-tip bristle toothbrushes when compared to end-rounded bristles toothbrushes. Additionally, better results may be expected in medium or hard toothbrushes, regardless of the bristle end-shape, in non-interproximal cleaners.

The efficacy of a rubber bristles interdental cleaner on parameters of oral soft tissue health-a systematic review

Aim

This study aimed to establish the efficacy of a rubber bristles interdental cleaner (RBIC) as an adjunct to toothbrushing (TB) compared to that of the adjuvant use of other interdental cleaning devices and TB alone on plaque and gingivitis parameters. Additionally, the safety aspects and panellists’ appreciation were evaluated.

Materials and Methods

Databases were searched for randomized controlled clinical trials (RCTs) evaluating plaque (PI), bleeding (BS), and gingival index (GI) scores, safety assessments, and participants’ appreciation. Extracted data were summarized in a descriptive and, if possible, a meta‐analysis.

Results

The search retrieved 142 unique papers; six studies with 10 comparisons were included in a descriptive analysis. Five RCTs compared RBICs with interdental brushes (IDBs), four with dental floss (DF) and one with manual TB only. No comparisons to wood sticks were retrieved. Using an RBIC resulted in no difference in plaque scores compared to DF and IDBs. For overall bleeding scores, no difference was found. Two studies analysing the accessible sites separately found RBICs to be more favourable than DF and IDBs. Conversely, one study evaluating the efficacy of RBICs compared to IDBs, according to the GI scores, showed that IDBs achieved significantly greater reduction. Moreover, RBICs caused fewer gingival abrasions and were preferred by the study participants.

Conclusion

Based on a descriptive and a meta‐analysis of the available literature, it is synthesized that in gingivitis patients, a weak to very weak certainty exists that a RBIC is indicated for gingivitis and plaque reduction. The evidence supports user safety and participants’ preferences.

The effect of cetylpyridinium chloride mouthrinse as adjunct to toothbrushing compared to placebo on interproximal plaque and gingival inflammation-a systematic review with meta-analyses

OBJECTIVES

The present study aimed to systematically review the literature about the interproximal anti-plaque and anti-gingivitis efficacy of cetylpyrydinium chloride (CPC) mouthrinse compared to placebo solution.

MATERIALS AND METHODS

Three databases (PUBMED, SCOPUS, and EMBASE) were searched for randomized clinical trials that compared the interproximal anti-plaque and anti-gingivitis effect of CPC and placebo mouthrinses as an adjunct to toothbrushing, after a minimum of 6 weeks. Individuals with any periodontal diagnosis were considered. Two meta-analyses were performed for the Turesky modification of the Quigley-Hein plaque index and the Löe and Silness gingival index. For both analyses, the mean differences (MD) between baseline and 6-weeks were calculated using a random-effect model.

RESULTS

Eight studies were included. All included studies showed significant improvement in at least one of the parameters, favoring the CPC mouthrinse when compared to placebo. The meta-analysis demonstrated that groups that used CPC displayed a significantly greater reduction in the plaque index score (MD; 95% confidence interval [95%CI]: - 0.70; - 0.83 to - 0.57) and in the gingival index (MD; 95%CI: - 0.38; - 0.47 to - 0.28) when compared to placebo. However, high heterogeneity was observed in both analyses (I² = 89% and I² = 98%, respectively).

CONCLUSIONS

When considering interproximal surfaces, CPC is efficacious both in plaque and gingival inflammatory parameters, demonstrating the potential to compensate for the limitations of interproximal plaque control.

CLINICAL RELEVANCE

CPC may be a good alternative to compensate interproximal plaque removal, improving interproximal gingivitis.

Knowledge and Skills Level on Oral Health Among Students at the "Ferdinand I" Military Technical Academy in Bucharest

The increase in the number of clinical cases with varying levels of damage to dental structures among young adults due to caries and excessive consumption of sweets and acidic beverages leads to questions about why there is an increase of cases despite all means of information. Is there a lack of interest in oral health among young adults? The aim of this study was to evaluate the knowledge and skills level of the students regarding oral health in order to conceive and implement an oral health educational program adapted to their needs and interests. The survey method using a questionnaire was administered to students in the first, second, and third academic year at the "Ferdinand I" Military Technical Academy (Bucharest, Romania) in March 2019 and included general data and specific information about oral health. We noted a relatively high participation in this study (73.91% agreed), although 71% have not participated in campaigns and training programs about oral health. The participants showed a high degree of interest in dental aesthetics, although 59% consider dental caries to be the main problem affecting their oral-dental health. It is imperative to introduce an educational module regarding oral health for military students, and not only, in order to materialize knowledge by adopting healthy attitudes and behaviors, avoiding high financial and biological costs for both the patient and the healthcare system.

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.
