RESUMO
AIM: To determine the efficacy of a water flosser (WF) compared to an interdental brush (IDB) in reducing gingival inflammation. Additionally, the products were compared on the incidence of gingival abrasion. METHODS: Young adults with moderate gingivitis and ≥4 accessible interdental spaces by IDB in each quadrant were selected for this study. Participants were randomly assigned a WF or an IDB as an adjunct to manual toothbrushing. Clinical signs of inflammation were measured in two randomly assigned contralateral quadrants by bleeding on pocket probing (BOPP) or bleeding on marginal probing (BOMP). Gingival Abrasion Score (GAS) was assessed per quadrant. Data was recorded at the baseline, 2 weeks and 4 weeks. RESULTS: Both groups WF (n = 40) and IDB (n = 38) showed a significant reduction (p = 0.000) in BOMP and BOPP from the baseline to 4 weeks for all sites and the interdental sites only. At 4 weeks the WF group compared to the IDB group showed significantly lower BOPP (p = 0.030) and BOMP scores (p = 0.003) for all sites. For the interdental sites WF showed compared to IDB for BOMP significant (p = 0.019) lower values but not for BOPP (p = 0.219). There were no differences between the groups for GAS at any time point. CONCLUSION: In patients with moderate gingivitis, after 4 weeks use the WF is more effective than the IDB in obtaining marginal gingival health.
RESUMO
AIM: New technologies such as tactile robots and artificial intelligence are about to find their way into clinical practice in dentistry and may contribute to the improvement of oral health care in the future. In this study we hypothesized that a collaborative, tactile robot programmed by a dental student removes interproximal artificial plaque as effectively as a human operator in an in vitro pilot trial. MATERIAL AND METHODS: Model teeth were fully covered with artificial plaque and set into phantom jaws. First, a robot was programmed by a dental student to perform interproximal cleaning with an interproximal brush. Second, teeth were covered with artificial plaque again and the dental student performed the interproximal cleaning manually. Both experiments were repeated five times. Residual plaque was measured with binary pictures. Surface coverage was reported and comparison of methods was performed with significance defined at a= 0.05. RESULTS: No statistically significant difference was found in the cleaning result between the robot and the human operator. CONCLUSION: The results of this in vitro pilot study indicate that a tactile robot with integrated artificial intelligence programmed by a dental student can perform interproximal cleaning as effectively as the dental student. Practical lmplications: In the future, the use of robot assistants to support oral hygiene, e.g., in patients with reduced motor skills or impaired vision may be further investigated.
RESUMO
OBJECTIVE: This randomized clinical trial aimed to compare the efficacy of an oral irrigator and an interdental brush in patients with peri-implant mucositis clinically and biochemically at different time points (at baseline and at the 2nd, 4th, and 12th weeks). MATERIALS AND METHODS: Forty-five patients with at least one implant with peri-implant mucositis were included in the present study (n = 45). The patients were divided into three groups: oral irrigator + toothbrush (OI group, n = 15), interdental brush + toothbrush (IB group, n = 15), and toothbrush only (control) (C group, n = 15). The modified plaque index (mPlI), modified sulcus bleeding index (mSBI), probing pocket depth (PPD), probing attachment level (PAL), and bleeding on probing (BOP) were recorded at baseline and at the 2nd, 4th, and 12th weeks. The levels of interleukin 1 beta (IL-1ß), transforming growth factor-beta (TGF-ß), tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) were also determined in the peri-implant crevicular fluid samples biochemically. RESULTS: The mSBI and t-PA at the 2nd week (p = 0.003; p = 0.003); the mPlI, mSBI, BOP, t-PA, and PAI-1 at the 4th week (p < 0.05; p < 0.001; p < 0.001; p = 0.015; p = 0.011); and the mPlI, mSBI, IL-1ß, t-PA, and PAI-1 at the 12th week (p < 0.05; p < 0.001; p = 0.013; p < 0.001; p = 0.002) were significantly lower in the OI group compared with those in the C group. Meanwhile, PAI-1 at the 2nd week, mSBI at the 4th week, and t-PA at the 12th week were significantly lower in the OI group compared with those in the IB group (p < 0.001; p = 0.011; p = 0.003). At the 2nd, 4th, and 12th weeks, all other parameters were not statistically different in the three groups. CONCLUSION: The clinical indexes (such as mSBI and BOP) that play an important role in the diagnosis of peri-implant mucositis showed the lowest means (although limited) in the OI group at all evaluation time points. Moreover, when the clinical and biochemistry results were interpreted altogether, it became apparent that the OI group exhibited similar or more effective results than the IB group in resolving peri-implant mucositis. In light of the foregoing, this study concluded that the use of an oral irrigator can be as effective as an interdental brush in interdental cleaning. CLINICAL RELEVANCE: In this study, it is suggested that the regular use of an oral irrigator along with a toothbrush could be an appropriate alternative to other oral hygiene products such as dental floss and interdental brush for the management of peri-implant mucositis by preventing the accumulation of dental plaque (NCT03844035).

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.

OBJECTIVES: Effective daily oral hygiene behaviour will prevent periodontal disease. This study aimed to examine the oral symptoms, oral hygiene behaviours and factors contributing to oral hygiene behaviours among patients with type 2 diabetes in a hospital in Japan. METHODS: A cross-sectional survey was conducted with 198 patients with type 2 diabetes. Oral symptoms were assessed using a dichotomous scale based on clinical guidelines. Oral hygiene behaviours were assessed based on the frequency of daily tooth brushing and the use of interdental cleaning aids. Chi-square tests and logistic regression analyses were also performed. RESULTS: Overall, 71.2% of the participants had oral symptoms. Of the participants, 80.3% performed twice daily tooth brushing and 61.1% did not perform interdental cleaning on a daily basis. Logistic regression analysis revealed that tooth brushing behaviour was negatively associated with male patients (odds ratio [OR] = 0.45, 95% confidence interval [CI]: 0.25-0.80), difficulty with mastication (OR = 0.63, CI: 0.43-0.92) and tooth loss (OR = 0.68, CI: 0.46-1.00) and positively associated with periodontal disease (OR = 1.73, CI: 1.10-2.72). There were no significant variables related to the use of interdental cleaning aids. CONCLUSIONS: Patients need to learn about the necessity for regular oral hygiene behaviours and the appropriate way. In particular, support for male patients, those who have difficulty with mastication, those who have experienced natural tooth loss, and those who have not been diagnosed with periodontal disease are needed.

OBJECTIVES: To compare the efficacy and patient-reported outcome measures of oral hygiene instruction methods for calibrated interdental brush. MATERIALS AND METHODS: A total of 60 participants, with 30 each in control and test group, participated in the study. Clinical examination included gingival index, full mouth bleeding scores and approximal plaque index. Supragingival scaling was performed. Interdental access probe was used to assess the size of interdental brush and corresponding interdental brush were given to the participants. For the control group, oral hygiene instructions were given through demonstration with model and video. For the test group, oral hygiene instructions were given through 'Touch-to-Teach' method. At 4-week follow-up, oral hygiene instructions were repeated to respective groups. After 3 months, clinical examination was done and exit survey on patient-reported outcome measures was administered. Statistical analysis was done. RESULTS: Intergroup comparison of gingival index, full mouth bleeding index and approximal plaque index showed statistically significant difference between test and control group. 'Touch-to-Teach' method of oral hygiene instruction was found to be 'Good'. Acceptance of interdental brush was regarded to be 'Good'. CONCLUSION: Within limitations of the study, Touch-to-Teach method of oral hygiene instruction method was found to be effective and more acceptable and participants used the interdental brush regularly.

OBJECTIVES: The aim of this split-mouth, prospective controlled study was to compare the effects of two different interdental devices on clinical plaque elimination, gingival bleeding and patient acceptance and comfort. MATERIALS AND METHODS: Thirty participants who had been diagnosed with gingivitis were included in the study. After professional oral prophylaxis and a 3-day washout period, patients were advised to use two test devices (TePe Interdental Brushes Original and TePe EasyPick™, Malmö, Sweden) according to instructions. The plaque index (Turesky modification of the Quigley and Hein Index) and bleeding index (Papillary Bleeding Index) were recorded at baseline and after 2 weeks. Patient satisfaction and comfort were assessed with a questionnaire. RESULTS: Both of the tested devices improved the plaque and bleeding index scores. There were no differences between the two sides in terms of time-dependent changes. The patients felt more satisfied with the cleansing capacity and more comfortable with the use of SCIP compared with IDB (p = 0.001). Pain sensation with the use of SCIP was significantly lower than with IDB (p = 0.002). CONCLUSION: The clinical efficiency of the tested interdental devices was similar in terms of removing plaque and decreasing bleeding. However, SCIP were found to be more comfortable and preferable to IDB. CLINICAL RELEVANCE: The silicone coated interdental picks showed similar effects on plaque removal as interdental brushes and superiority in terms of ease to use than interdental brushes.

Elderly patients often find it challenging to remove plaque accumulated on the attachments of implant overdentures (IODs) using conventional cleaning instruments. Further, excessive plaque accumulation can lead to peri-implant diseases and occasionally to respiratory diseases. Therefore, here, we aimed to compare the effectiveness of waist-shaped interdental brushes (WIBs) with that of straight-shaped interdental brushes (SIBs) in plaque removal from the locator attachments of IODs. Twenty participants with 2 locator attachments retaining mandibular IODs participated in this study. After the baseline cleaning, the participants refrained from oral hygiene maintenance for 3 days. A dentist cleaned 1 of the attachments using the WIB and the other attachment using the SIB. The pre- and post-cleaning modified plaque index (mPLI) scores were recorded. After another 3 days free from oral hygiene maintenance, the trained participants repeated the same cleaning procedure using the WIB and SIB. Pre- and post-cleaning mPLI scores were recorded. Regardless of the type of brush used, the post-cleaning mPLI scores were lower than the pre-cleaning scores. After the cleaning procedure, the overall mean mPLI score was lower in the WIB group than in the SIB group. The post-cleaning mPLI scores at the line angles and on the axial surfaces of the attachments were also lower in the WIB group than in the SIB group. There was no difference in the cleaning effectiveness between the dentist and participants when they used the same type of interdental brush. The WIB was significantly more efficient in plaque removal than the SIB, especially at the line-angle sites.

Many types of interdental instrument, such as dental floss and interdental brushes, can be purchased easily and sell in large numbers. Many studies have compared the effects of such instruments. Few studies have investigated their relationship with regions of residual plaque, however. The purpose of this study was to compare rates of plaque removal from the mesial and distal surfaces of the bilateral maxillary and mandibular premolars and molars among 3 types of interdental instrument: finger-winding-dental floss, holder-type dental floss, and an interdental brush. Prior to the experiment, the artificial teeth in a jaw model were removed for application of artificial plaque. The teeth were then replaced and the model attached to a phantom. An operator brushed the teeth in a posture close to that adopted in actual tooth brushing with each type of instrument, after which the plaque removal rate was compared among them. The rate of plaque removal using finger-winding floss was the highest, although this type of instrument is less easy to hold than the others. The rate with a handle-equipped interdental instrument showed a decrease in some regions, although it is easy to hold. The results of this study suggest that the type of interdental instrument used should differ depending on the region to be cleaned.

BACKGROUND: The purpose of this study was to evaluate the mitigating effect of the use of interdental brushes on periodontal health inequality. METHODS: This study was based on the data acquired in the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI; 2013-2015). A total of 17,583 participants (7,633 males and 9,950 females)) aged 19 years or older completed the KNHANES VI between 2013 and 2015. Multivariable logistic regression analysis was performed using socioeconomic characteristics (sex, age, level of education, individual income), personal health practice (smoking, toothbrushing, dental flossing, interdental brushing, dental clinic visiting), systematic medical factors (diabetes mellitus, hypercholesterolemia, hypertension, obesity) and the community periodontal index. We confirmed differences in the prevalence of periodontal disease with the use of an interdental brushes stratified according to individual income. RESULTS: Three logistic regression models adjusted for covariates hierarchically. In all models, individuals who used an interdental brush were not significantly different from individuals who did not use an interdental brush. The adjusted odds ratio (OR) for interdental brushing was 0.918 with a 95% confidence intervals (CIs) of 0.797-1.057. When periodontal disease was the outcome of the model, the lowest income group had 1.266 (95% CIs 1.066 to 1.502) times the odds of having periodontal disease than the highest income group. In interdental brush nonusers, the lowest income group had 1.276 (95% CI 1.061-1.533) times the odds of having periodontal diseases than the highest income group. However, in the interdental brush users, there were no significant differences in periodontal disease prevalence among income groups. CONCLUSIONS: The results suggest that the use of interdental brushes could alleviate periodontal health inequality.

AIM: The aim of this study was a comparison of the handling and acceptance of two kinds of interdental brushes (interdental brush with a handle [HB] and a newly invented interdental cleaning device [NB]). METHODS AND MATERIALS: In a randomized crossover trial, 40 test subjects with an average number of 23.5 interdental areas were examined. At two appointments with a "washout" period of one week, the volunteers tried out both cleaning tools (HB and NB). They were asked to clean as many interdental spaces as possible. The percentage of spaces, which could be reached, is the IRI (Interdental Reachability Index). Furthermore, subjective impressions were determined. RESULTS: The average IRI using HB was 64% compared to 80% using of NB (P<.001); 62.5% of the volunteers found the cleaning with HB painful and 15% the cleaning with NB. The subjective feeling after cleaning was 1.75 with NB compared to 2.2 with HB (P=.015), grading the feeling, from 1 for "very good" to 5 for "poor." The acceptance of regular interdental hygiene was rated 1.95 in the case of the NB and 2.85 in the case of the HB. After both appointments, the test subjects declared that they would use the NB 3.05 times and the HB 1.78 times a week. CONCLUSION: This study shows that the test subjects reached more interdental spaces with NB than with the HB. NB can improve the usage of interdental brushes. Regarding subjective comfort, participants also favoured NB over HB.

AIM: To determine the efficacy of a rubber bristles interdental cleaner (RBIC) compared to an interdental brush (IDB) in reducing gingivitis and additionally to evaluate participants' attitudes and possible side effects. MATERIAL AND METHODS: The study was a 2-treatment, parallel, split-mouth, examiner-blind RCT, evaluating the reversal of experimental gingivitis. In total, 42 systemically healthy volunteers were recruited that were currently non-users of interdental cleaning devices. After familiarization and prophylaxis, participants refrained from brushing mandibular teeth for 21 days, followed by 4-week product use of the assigned interdental cleaning device as adjunct to manual toothbrushing. Bleeding on marginal probing (BOMP), dental plaque index score (PI) and gingival abrasion score (GAs) were assessed in the lower jaw. RESULTS: Overall, no statistically significant differences between the RBIC and IDB in reducing BOMP and PI were obtained. Analysing the sites that were accessible for the RBIC/IDB only showed that the sites treated with the RBIC had significantly less BOMP after 4 weeks (P = .009). The RBIC also caused less GAs (P => .016) and was considered more pleasurable to use by the participants (P = .0001). CONCLUSIONS: In accessible sites, the RBIC, in conjunction with manual toothbrushing, was found to be more effective in reducing gingival inflammation after 4 weeks. The RBIC caused less abrasion of the gingiva and was appreciated more by the participants.

AIM: Comparison of different interdental aids efficiency in patients with healthy periodontium. METHODS: A non-randomized controlled split-mouth study was carried out in 25 young adults with healthy periodontium. The mouth was divided into 4 quadrants. All the participants used manual toothbrush. Additional hygienic aids included SPS prime (Curaprox) interdental in quadrant 1 brushes, dental floss (Curaprox) in quadrant 2, unituft toothbrush (Curaprox) in quadrant 3, no interdental aids were used in quadrant 4. The oral hygiene efficiency was assessed after 4 weeks with Silness-Loe Plaque Index (PI) and Rustogi et al. Modified Navy Plaque Index (RMNPI). RESULTS: After 4 weeks the mean value of PI decreased from 1.2±0.27 to 0.7±0.28, the mean value of RMNPI decreased from 0.7±0.11 to 0.5±0.16. At the primary examination, there was no statistically significant difference of PI and RMNPI values between the quadrants. After 4 weeks, ANOVA test demonstrated significant difference between the quadrants. The minimal PI and RMNPI values were determined in quadrant 1 (0.4±0.16 and 0.3±0.11, respectively). The maximal PI and RMNPI values were determined in quadrant 4 (1.0±0.21 and 0.6±0.14, respectively). There was no significant difference between quadrants 2 and 3. CONCLUSION: In limitations of this study, the maximal oral hygiene efficiency was achieved with use of manual toothbrush combined with interdental brush.

AIM: The purpose of this study was to compare the effectiveness of conically shaped versus cylindrically shaped interdental brushes (IDB) in patients receiving supportive periodontal therapy. MATERIALS AND METHODS: Periodontal maintenance patients volunteered to be enrolled into this randomized controlled examiner-blind parallel study. At baseline and after 3 months, plaque scores, bleeding upon pocket probing scores and probing pocket depth (PPD) were assessed. The type of IDB (conical or cylindrical) was randomly assigned to each patient and individual instruction was provided regarding the method of use and the appropriate size. Only those approximal sites that had sufficient space for the IDB were eligible, and for those sites the data were analysed separately. Analyses were performed for all eligible approximal surfaces and a sub-analysis was performed for vestibular and lingual surfaces. RESULTS: In total, 51 participants attended the baseline and the 3-month clinical appointments. Overall, there was no difference between conical and cylindrical IDBs. However, the conical IDB showed significantly higher plaque and bleeding scores at the lingual approximal sites. The cause of this difference was an increase in plaque and bleeding scores compared with baseline. With respect to the PPD, no difference between the IDBs was observed. CONCLUSION: Within the limitations of this experiment, the conical IDBs are less effective than cylindrical IDBs with respect to lingual approximal plaque removal. Thus, in patients receiving supportive periodontal therapy, the cylindrical shape should be the first choice of IDB to obtain and maintain gingival health around natural teeth.

OBJECTIVES: The purpose of this randomized, single-use, single-blind, two-group, parallel pilot study was to compare the plaque removal ability of a water flosser and interdental brush when used in combination with a manual toothbrush. METHODS: Twenty-eight (28) subjects completed the study. Subjects were randomly assigned to one of two groups: Waterpik®Water Flosser (WF) plus manual tooth brushing or interdental brushes (IDB) plus manual tooth brushing. Pre-cleaning plaque scores were obtained using the Rustogi Modification of the Navy Plaque Index (RMNPI). Subjects were instructed on the use of their interdental product. Post-cleaning scores were obtained after a supervised brushing and use of the interdental device. Scores were recorded for whole mouth, marginal, approximal, facial, and lingual regions for each subject. RESULTS: There were no differences between the groups for pre-cleaning plaque scores for whole mouth, marginal, approximal, facial, or lingual regions. Both groups showed significant reductions in plaque from baseline for all areas measured (p < 0.001). The WF group was significantly more effective than the IDB group for removing plaque from all areas measured. Specifically, the WF was 18% more effective for whole mouth and marginal areas, 20% for approximal areas, 11% for facial areas, and 29% for lingual areas. CONCLUSIONS: The Waterpik Water Flosser and manual toothbrush removes significantly more plaque from tooth surfaces (whole mouth, marginal, approximal, facial, and lingual) than interdental brushes and a manual toothbrush after a single use.

OBJECTIVES: The purpose of this randomized, two-week, single blind, two-group parallel pilot study was to compare the reduction in gingival bleeding and plaque in subjects using a water flosser or interdental brush, each combined with a manual toothbrush. METHODS: Twenty-eight subjects completed the study. Subjects were randomly assigned to one of two groups: Waterpik® Water Flosser (WF) plus manual toothbrush or interdental brushes (IDBs) plus a manual toothbrush. Bleeding on probing (BOP) was measured at six sites and reported for whole mouth, lingual, facial, and interproximal areas. Plaque data were measured using the Rustogi Modification of the Navy Plaque Index (RMNPI) and were reported for whole mouth, approximal, marginal, facial, and lingual areas. Subjects received verbal and written instructions on the use of their interdental product and demonstrated proficiency prior to starting the study. RESULTS: There were no differences between the groups for BOP or RMNPI at baseline. Both groups demonstrated a significant reduction in BOP and RMNPI for all regions and areas measured from baseline to two weeks. The WF was more effective than the IDBs for BOP whole mouth (56%), facial (44%), approximal whole mouth (53%), and approximal facial (41%). Post hoc power analysis showed that the sample size was not adequate to detect a significant difference between groups for lingual and marginal assessments for BOP or any area for RMNPI. CONCLUSIONS: The Waterpik Water Flosser is more effective than IDBs for reducing gingival bleeding over two weeks.

PURPOSE: This study aimed to develop a systematic interdental brush set with size distribution based on the passage hole diameter (PHD), addressing existing gaps in size selection criteria for effective interdental cleaning. MATERIALS AND METHODS: In the first step, an interdental brush set that ascends stepwise according to the PHD value was envisioned. The study was divided into three phases: (i) in-vitro determination of PHD values of a currently existing assortment on the market by 13 calibrated dental professionals, (ii) in-vitro assessment of forces during insertion, and (iii) creation and evaluation of new prototypes for missing or non-matching PHD sizes. Intra- and inter-rater reliability, assessed with the intraclass correlation coefficient (ICC), as well as insertion forces and PHD sizes at all stages were reported. RESULTS: In the existing range, three interdental brushes fitting the desired PHD sizes were initially identified. Mean insertion forces between 0.3 and 1.7 N were documented based on raters' PHD choices. Two additional rounds of measurements with prototypes adapted in diameter and shape were necessary, particularly for PHD values of 1.4, 2.3 and 2.6. High intra- and inter-rater reliability was observed throughout the study (ICC > 0.95), ensuring consistent evaluations. After three rounds of assessments, a prototype was successfully identified for each targeted PHD value in the systematised set, showcasing reliable sizing and insertion forces. CONCLUSION: Using a structured approach, a comprehensive interdental brush set was developed with reliable PHD sizing and moderate insertion forces. The verification of size reliability through measurements by dentists represents a novelty in development and underlines the importance of accurate brush size selection for optimal biofilm control. Whether a systematic set based on the PHD value offers added value for clinical practice, and at what intervals, must be demonstrated in further studies.

Background Plaque and dental caries are the primary agents causing gingival and periodontal diseases, eventually progressing into tooth loss. If oral hygiene practice is poor, plaque easily accumulates on the tooth surface, especially in interproximal areas. To maintain a good oral environment, it is mandatory to remove or at least reduce the percentage of plaque formation from the oral cavity. To achieve this, interdental aids should be used along with toothbrushes, as cleansing the teeth only with a toothbrush is not effective. Various interdental aids, like interdental brushes, floss, toothpicks, etc., are now available on the market. The objective of the current survey was to rate knowledge as well as make a comparison between the cleaning effectiveness of interdental brushes and interdental floss to determine which was better at reducing plaque accumulation and, subsequently, dental caries. The survey was accessed by measuring individual plaque and gingival index before and after using interdental cleaning aids. Methodology The objective of the survey was to evaluate and analyze the efficiency of interdental brushes and interdental floss in maintaining oral hygiene among orthodontic patients residing in the Vidarbha region. After receiving approval from the Ethical Committee DMIHER(DU)/IEC/2023/721, a study was conducted over a 30-day period, focusing on a group of 100 individuals aged between 15 and 30 years, and their assessments were analyzed. The patient was briefed about the study and asked to make use of an interdental brush and interdental floss. The gingival index and plaque index were calculated on the same patients before and after the use of the interdental brush and interdental floss to determine which was better at reducing plaque accumulation on the surface of teeth. Descriptive analysis, unpaired for intergroup comparison, and paired T-tests for intragroup comparison were used. The software used was SPSS 24.0 (IBM Corp., Armonk, NY) and GraphPad Prism 7.0 (GraphPad Software, Inc., La Jolla, CA). Result Everyone's tooth surfaces naturally develop a thin layer of plaque biofilm, but the presence of heavy plaque deposits on teeth indicates poor dental hygiene, which can lead to various oral health issues. Failure to improve dental hygiene status can result in problems such as halitosis, gingival issues, periodontal disease, and eventually tooth loss. Dentists play a crucial role in raising awareness about these concerns among their patients and providing education on effective oral care practices, including the use of interdental aids in conjunction with toothbrushes. When comparing the effectiveness of interdental brushes and dental floss in removing plaque, interdental brushes have been found to be more efficient. They not only excel in plaque removal but also contribute to a reduction in gingival problems. The statistical analysis supports this, with a significant p-value of less than 0.01 for both the plaque index and gingival index when using interdental brushes, indicating their superior performance in maintaining oral health. Conclusion The study will help every individual improve their oral hygiene status with the help of an interdental aid and a toothbrush. This will reduce the chances of having gingival and periodontal diseases and eventually reduce the risk of tooth loss.
RESUMO
This study aimed to review the use of interdental care products (ICPs) among adults in Korea, reconfirm their relevance to periodontal health, and identify factors affecting the use of ICPs. Data from 2007 to 2018 from the National Health Nutrition Survey (KNHANES) were used, and 43,069 adults (18,412 men, 24,657 women) aged 30 years or older were included. The frequency and percentage of ICP use according to the characteristics of the subjects are presented. In addition, multivariate logistic regression analysis identified the factors affecting ICP use. The ICP usage rate of participants in the KNHANES phase gradually increased to 22.8% in the 4th, 26.4% in the 5th, and 38.0% in the 6th phase and then decreased to 36.3% in the 7th phase. The adjusted OR values for periodontal health in ICP users were 0.721 for gingivitis and 0.642 for periodontitis, confirming that ICP was associated with a lower prevalence of these conditions. Sex, age, educational level, household income, toothbrushing, and dental check-ups were related to ICP use in all phases. ICP was associated with improved periodontal health, but its use rate was very low. Therefore, oral health professionals should educate adults on the use of ICP, particularly interdental brushing.

Purpose: The purpose of this crossover clinical trial was to compare the changes in scores of plaque biofilm accumulation, gingival inflammation, gingival bleeding and gingival trauma in patients who used conventional flossing (CFt), knotted floss (KFt) and an interdental brush (IBt) for 6-weeks each in Type II gingival embrasures.Methods: Sixty healthy, tooth-brushing adults with at least one Type II gingival embrasure were randomly assigned to perform any of above interdental cleaning techniques in each phase of six weeks. Crossover to another technique was undertaken after washout of 2 weeks. Test-sites were scored at baseline, 3 and 6 weeks for Rustogi Modification of Navy Plaque Index (RMNPI), Modified Gingival Index (MGI), Modified Papillary Bleeding Index (MPBI), and Carter-Hanson scoring for gingival trauma. Acceptability of each technique was evaluated by subjects' responses to the post-trial questionnaire.Results: Analysis of data showed a significant improvement in RMNPI, MGl and MPBI scores within all three groups over the time-period of 6-weeks from baseline. RMNPI and MGI scores were significantly more in the CFt group when compared to KFt and IBt and there was no difference in KFt and IBt. Additionally, no significant gingival trauma was recorded in any test group. Equal percentages of participants selected KFt or IBt for its ability to clean and preference to continue to use.Conclusion: Use of a KFt and IBt are statistically similar in safety and efficacy for reducing plaque biofilm accumulation, gingival inflammation, and bleeding in Type II gingival embrasures, when either is used as an interdental cleaning aid in conjunction with regular tooth-brushing. KFt and IBt demonstrated better efficacy than CFt.
