RESUMO

At present, the most important criterion for the size selection of interdental brushes is the PHD-value (passage hole diameter) according to the ISO standard for interdental brushes ISO 16409:2016. The PHD size range of commercially available products currently lies between 0.6 and 5.2 mm. With the exceptions of special situations, a range between 0.7 and 2.9 mm is sufficient for clinical routine. As most products have longer filaments nowadays, one brush can often be applied for two PHD intervals. Consequently, adequate patient counseling and the individual selection of the appropriate interdental brushes can generally be achieved with an assortment of 12 systematically arranged interdental brush sizes. An application example is the "Heidelberg set" described herein. It is crucial that the correct choice of size is based upon continuously rising PHD-values, and not upon parameters such as stem size, outer diameter of filaments, or similar, as these do not allow for a reliable conclusion regarding the interdental passage. The usage of ISO sizes is also not recommendable due to their insufficient size differentiation.

RESUMO

Purpose: The purpose of this study was to investigate the effects of a professional oral health care program on the oral health status and salivary flow of elderly people living in nursing homes.Methods: Elderly residents aged ≥ 65 years, living in a nursing home, were randomly assigned to either a one-week interval, two-week interval, or control group, and received an oral health intervention accordingly over a period of 12 weeks. Plaque index, tongue coating, gingival index, and salivary flow rate were compared before and after the oral health intervention within and between the groups.Results: The plaque, tongue coating, and gingival indices of the participants who received the oral health intervention decreased significantly; while the salivary flow rate significantly increased. Plaque, tongue coating, and gingival indices decreased most significantly in the one-week interval group, followed by the two-week interval group, relative to the control. The salivary flow rate increased most significantly in the one-week interval group, followed by the two-week interval group.Conclusion: A professional oral health care program is effective for improving the oral health and salivation of elderly residents in nursing homes and the effect was found to be greater with interventions provided at one-week intervals. Oral health care professionals, including dentists and dental hygienists, must regularly monitor and manage the oral health of elderly residents.

RESUMO

Purpose: The purpose of this study was to evaluate the effect of different motivational methods on children's oral hygiene and periodontal health. Methods: A prospective, controlled, single-blinded, randomized clinical trial was conducted with 60 six- to 12-year-olds who were randomly assigned to toothbrushing with an hourglass timer, music video, or control group. All three groups were divided into two equal subgroups: those using a manual toothbrush and those using a powered toothbrush. The plaque index (PI) and gingival index (GI) were measured in each group. The data obtained were analyzed using three-factor variance analysis. Results: A statistically significant decrease was observed in PI and GI values in all groups (P<0.05). The highest decrease in PI values was observed in the group brushing with a music video and a powered toothbrush (51.8 percent), whereas the least decrease was observed in the control group using a powered toothbrush (26.1 percent). The differences were not statistically significant among the groups. Conclusions: A significant decrease in plaque index and gingival index values was obtained in all groups compared to baseline values. Although the additional motivational methods used during toothbrushing contributed to improved plaque removal and toothbrushing efficiency, no statistically significant differences were found among the groups.

RESUMO

PURPOSE: In periodontally healthy individuals, mean crevicular depth ranges from 1 to 3 mm. This depth threshold has been used as an indicator to differentiate a physiological dentoalveolar sulcus from a periodontal pocket needing further treatment. Because many studies have shown the important contribution of oral hygiene status to periodontal health, the purpose of this study was to explore the clinical effect of reinforced oral hygiene on the periodontal status of periodontitis-free dental students. MATERIALS AND METHODS: In our longitudinal observational clinical study, we assessed the periodontal status of healthy individuals attending the dental school by measuring the periodontal pocket depth, bleeding on probing, and plaque index. The follow-up reassessment was carried out four years later at the end of the dental curriculum. RESULTS: The study showed that oral hygiene improvement led to a slight but significant reduction in the mean sulcus depth (-0.049 mm; p<0.0001). CONCLUSIONS: Reinforcement of oral hygiene contributes to the reduction of probing depth even in periodontally healthy patients.

RESUMO

Objective: To investigate of effects of using phase-contrast video technique on education in oral hygiene training. This one blind, parallel randomized controlled trial was conducted in a tertiary clinic. Fifty-three patients who presented to the orthodontics department aged 12-20 years were divided into two groups randomly by computer-generated assigned codes to receive oral hygiene education. The participants were blinded to type of education method. Before orthodontic therapy, the control group was trained only by the conventional method, while the test group was trained by phase-contrast video microscopy method in addition to conventional method. Some images and videos of moving microorganisms in dental plaque were shown to the patients in test group on a computer monitor. Subjects and Methods: The bacterial count, plaque index, and gingival index scores were compared. Measurements were obtained in baseline and follow-ups which were repeated with 1-month intervals after the training. Results: The plaque index scores (1.05 ± 0.1 vs. 1.43 ± 0.2; P < 0.001) and gingival index scores (0.90 ± 0.1 vs. 1.14 ± 0.2; P < 0.001) in test group was statistically lower than those in control group at the end of the study. The gingival index scores reduced by 39% in test group vs. 14% in control group. The number of bacteria significantly decreased in the group trained with phase-contrast video microscope technique (8,059,133 ± 3016 vs. 10,830,600 ± 4919; 0.018). Conclusions: The training with phase-contrast microscopy has a more positive effect than the traditional method in oral hygiene education.

RESUMO

PURPOSE: The purpose of this study was to investigate the periodontal status in adult periodontal disease patients with malocclusion treated with digital clear aligners. METHODS: Thirty-three patients with periodontal disease who needed orthodontic treatment were selected. The patients were randomly divided into 2 groups, digital clear aligners group (experimental group, 16 patients) and fixed appliances group (control group, 17 patients). Bleeding index (BI), probing depth(PD), plaque index(PLI) and gingival index(GI) were recorded at baseline and 1, 3, 6 and 9 months during orthodontic treatment. SPSS 17.0 software package was used to analyze and compare the data of periodontal status between two groups. RESULTS: 1, 3, 6, and 9 months after orthodontic treatment, clinical parameters of the control group were significantly higher than baseline(P<0.05). The same measurements of the experimental group showed no significant differences at 1, 3, 6, and 9 months of treatment (P>0.05). After 1, 3, 6, and 9 months of treatment, the clinical parameters of BI, PLI and GI in the experimental group were significantly lower than the control group(P<0.05); PD in the experimental group was smaller than the control group, but there was no significant difference(P>0.05). CONCLUSIONS: Compared with conventional fixed appliance, clear aligner of digitalization can more effectively maintain periodontal heath in adult periodontal disease patients with malocclusion.

RESUMO

PURPOSE: To study the effect of chlorhexidine combined with mechanical debridement on peri-implant inflammation and the influence on SF-36 score of patients. METHODS: One hundred patients with peri-implantitis admitted to Zhejiang Provincial People's Hospital from January 2015 to January 2019 were selected and randomly divided into control group and combined group with 50 cases in each group according to random number table method.Patients in both groups were treated with mechanical debridement, and patients in the combined group were gargled with chlorhexidine gargle apart from mechanical debridement. Plaque biofilm average activity and modified plaque index (mPLI), bleeding on probing (BOP), modified sulcus bleeding index (mSBI), probing the depth (PPD), clinical attachment level(AL) were measured before and after treatment. Sf-36 scale and VAS visual pain score were used to evaluate the quality of life and pain degree of patients, and the therapeutic effect and incidence of complications were assessed. The data were analyzed with SPSS 20.0 software package. RESULTS: There was no significant difference in average activity, mPLI, mSBI, AL, PPD, BOP, VAS and SF-36 scores between the two groups before treatment(P>0.05); after treatment, the average activity, mPLI, mSBI, AL, PPD, BOP and VAS scores of plaque biofilm in the combined group were significantly lower than those of the control group, and the total effective rate of SF-36 score was significantly higher than that of the control group. The total effective rate of the combined group was significantly higher than that of the control group(P<0.05). The incidence of complications in the combined group was significantly lower than that in the control group(P<0.05). CONCLUSIONS: Chlorhexidine combined with mechanical debridement is an effective treatment of peri-implantitis, which can effectively inhibit plaque biofilm activity and plaque formation, alleviate pain and improve the quality of life of patients.

RESUMO

OBJECTIVE: We sought new markers to predict oral malodor. STUDY DESIGN: Seventy-five adults complaining of oral malodor were classified into 3 groups clinically: no oral malodor, physiologic oral malodor, and periodontitis-derived oral malodor. In addition to conventional clinical parameters, 7 salivary components, occlusal force, and lip-closing force were compared among the groups. RESULTS: Concerning the salivary components, cariogenic bacteria, occult blood, leukocytes, and ammonia differed significantly among the groups. Multiple logistic regression analyses indicated that tongue-coating scores and ammonia levels were significantly associated with genuine oral malodor, including physiologic oral malodor and periodontitis-derived oral malodor, and the tongue-coating score, plaque index, and occult blood level were significantly associated with periodontitis-derived oral malodor. Occlusal force and lip-closing force did not differ among the groups. However, there was a statistically significant interaction between occlusal force and lip-closing force in oral malodor in women (P = .019). CONCLUSIONS: Novel salivary markers, ammonia levels, and occult blood levels may predict genuine oral malodor and periodontitis-derived oral malodor, respectively. An interaction effect between occlusal force and lip-closing force on oral malodor was identified in women.

RESUMO

PURPOSE: To compare the effectiveness in reducing plaque and gingivitis of a fluoride toothpaste with 20% baking soda and a fluoride toothpaste control. METHODS: 159 subjects, who met the entry criteria, participated in this single-center, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed after 4, 8, and 12 weeks use of the assigned test or control toothpaste. After 12 weeks, participants resumed 4 weeks of their customary oral hygiene after which they were re-evaluated using the same measures. RESULTS: Both toothpastes statistically significantly reduced MGI, GBI, and PI versus baseline at all-time points. Brushing with the 20% baking soda toothpaste statistically significantly reduced MGI, PI, and GBI compared to the control toothpaste at all time points. After 12 weeks, the reductions in MGI, PI, and GBI were 12.6%, 9.6%, and 44.2%, respectively. After the 4-week customary oral hygiene period, the benefits of the study period had begun to diminish, but statistically significant reductions in MGI and GBI for the test versus control were still evident. This 3-month clinical study shows that brushing with fluoride toothpaste containing 20% baking soda reduces dental plaque and concurrently reduces gingival inflammation and bleeding compared to toothpaste with fluoride alone. CLINICAL SIGNIFICANCE: Fluoride toothpaste with 20% baking soda has the potential to offer multiple oral health benefits when used as an adjunct to regular tooth brushing and, therefore, may be confidently recommended to patients.

RESUMO

PURPOSE: To compare the effectiveness in reducing plaque and gingivitis of two fluoride toothpastes containing baking soda (35% and 20%) with a fluoride toothpaste control. METHODS: 319 subjects, who met entry criteria, participated in this single-center, three-cell, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed at baseline, and after 6 weeks, 3 and 6 months. RESULTS: All three toothpastes significantly (P< 0.0001) reduced MGI, GBI, and PI versus baseline, and the two baking soda toothpastes significantly (P< 0.0001) reduced MGI, GBI, and PI compared to the fluoride control, at all three time points. After 6 months use, the 35% and 20% baking soda toothpastes had reduced MGI, GBI and PI by 15.0%, 46.9%, and 18.3%, and 9.4%, 25.9%, and 12.4%, respectively, compared to the control. In addition, the 35% baking soda toothpaste had reduced (P≤ 0.0005) MGI, GBI, and PI by 6.2%, 28.4%, and 6.8%, respectively, compared to the 20% baking soda toothpaste. This clinical study showed that brushing with fluoride toothpastes containing baking soda at 35% and 20% reduces plaque, gingival inflammation and bleeding more effectively than regular fluoride toothpaste. Further, it showed that 35% baking soda toothpaste was more effective in reducing these parameters than 20% baking soda toothpaste. CLINICAL SIGNIFICANCE: Fluoride toothpastes containing 20% or more baking soda can provide significant and meaningful gingival health benefits when used regularly as an adjunct to tooth brushing.

RESUMO

AIMS: The purpose of the present study was to compare the effect of a new mouth wash formulation consisting of chlorhexidine and chitosan on dental plaque and its reduction to that of chlorhexidine or chitosan alone. MATERIALS AND METHODS: This study was a single-blind randomized clinical trial with a parallel group design of 3 months duration. Patients (20-40 years) who fulfilled the inclusion and exclusion criteria were assigned equally to group 1: chlorhexidine (0.2%), group 2: chitosan (0.5%) or group 3: chlorhexidine - chitosan combination group. The clinical parameters were recorded at baseline, 6weeks and at 3months. All patients received thorough oral prophylaxis and were instructed to rinse with 10ml of mouthwash twice daily for 1 minute. RESULTS: The combination of chitosan and chlorhexidine showed a statistically significant reduction (p less than0.05) in plaque indices from baseline at all time intervals when compared to that of chlorhexidine or chitosan alone. CONCLUSIONS: Our study demonstrates that by unifying the properties of chitosan and chlorhexidine may result in a superior antiplaque effect than that of chlorhexidine alone.

RESUMO

The study aimed to determine if oral hygiene influences not only oral health but also potentially metabolic disorders such as overweight or obesity. Participants were 94 patients: 40 with increased body mass and 54 with normal body mass. The methods included dental examination, a questionnaire concerning hygienic habits and an assessment of selected salivary inflammatory markers. The new parameter named "cleaning index" (describing the interaction between average time of tooth brushing in minutes and its frequency per day) significantly correlated with Body Mass Index (RSpearman = 0.300). The multivariate regression model incorporating cleaning index, approximal plaque index, receptor 1 for tumor necrosis factor-alpha (TNFα-R1) and interleukin-15 (IL-15) had a high power to predict overweight or obesity (AUC = 0.894). Patients with poor oral hygiene (approximal plaque index >40%) were more than eight times more likely to suffer from obesity than patients with good oral hygiene. Cleaning index higher than 4 decreased the odds by about 85%. Oral hygiene habits, adjusted by salivary concentrations of selected inflammatory markers may allow predicting effectively overweight or obesity risk. Early proper dental prophylaxis and treatment could lead to the better prevention of metabolic disorders.

RESUMO

The aim of this study was to evaluate changes in periodontal status and maxillary buccal bone by considering clinical and tomographic parameters during the first year of orthodontic expansion with Invisalign® aligners. Upper first (1PM) and upper second (2PM) premolars of 19 patients with orthodontic expansion requirement treated with Invisalign® aligners were evaluated. Plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and cone beam tomographic (CBCT) records were collected at 76 sites before starting treatment (T0) and at 12 months (T1). Bone height was measured from cementoenamel junction (CEJ) to the crest cortical bone (CC). Bone thickness was measured at two levels: 4 mm (CEJ+4) and 6 mm (CEJ+6) apical to the CEJ. A descriptive analysis was made of the variations of bone thickness and height in a series of cases. The average expansion was 1.93 mm for 1PM and 167 mm for 2PM. Arithmetic mean of distance CEJ-CC in 1PM was 3.05 mm at T0, and remained at 3.05 mm at T1. Arithmetic mean of distance CEJ-CC in 2PM was 2.06 mm at T0 and 2.31 at T1. Post-expansion, most of the analyzed sites (86%) exhibited a bone thickness of ≥0.5 mm. The greatest variations between T0 and T1 were observed at the level of 1PM CEJ+ 4 and 2PM CEJ+ 6. The minimal changes in the clinical records (GI, PI, PPD and CAL) between T0 and T1 were compatible with the maintenance of gingivalperiodontal health. Invisalign® for expansion movements did not produce substantial changes in the evaluated periodontal clinical parameters or in the bone measurements. Removable appliances reduce plaque retentive factors and favor adequate oral hygiene.

RESUMO

AIM: The aim of this study was to evaluate and compare two different techniques for the treatment of plaque-induced gingivitis, demonstrating whether the causal therapy supported by diode laser can allow a resolution of the edema caused by gingivitis in less time compared to the single traditional causal therapy. MATERIALS AND METHODS: Twenty-five patients between 20 and 60 years of age with a specific diagnosis of gingivitis were evaluated at the CLID-HSR oral hygiene department. Once the clinical parameters (bleeding index, plaque index, recession, and clinical attack level) were recorded, each of them was subjected to a professional oral hygiene session and instructed in correct home hygiene procedures. Through a split-mouth protocol for each individual patient, hemi-arches were treated by simple randomization to be treated with causal therapy supported by the action of the diode laser (experimental therapy) and which with traditional causal therapy (control therapy). A first intraoral scan was performed before therapy (T0), which was repeated 20 min after rinsing with CHX. The intraoral scans were repeated at a control 7 (T1) and 14 days (T2) after the session. For each intraoral scan, a volumetric value was calculated, proportional to the edema of the gingival tissues, using special digital software. The operator who carried out the volumetric measurements on the software was not aware of the therapy implemented on each half-arch. The operator who carried out the statistical analysis was not aware of the therapy applied to each group. The collected data were statistically compared in order to detect any differences between the volumetric variations between the two therapy groups and within the therapy groups over time. After evaluating the distribution of data by means of the Kolmogorov-Smirnov statistical test, the appropriate nonparametric tests were chosen to carry out the statistical comparisons. RESULTS: Based on the analysis of the gingival-periodontal health parameters and the volumetric value of the treated areas, no statistically significant differences were detected between the areas treated with the adjuvant action of the diode laser compared to those treated with causal therapy alone. CONCLUSIONS: With the limitations of this study, in accordance with the statistical results obtained, diode laser therapy does not allow a faster resolution of gingival edema compared to traditional therapy; the two treatment techniques for plaque-induced gingivitis, therefore, have the same efficacy.

RESUMO

OBJECTIVES: To assess peri-implant tissue conditions on the short term in patients receiving the Sub-periosteal Peri-implant Augmented Layer (SPAL) technique and in patients with adequate thickness (≥2 mm) of the peri-implant buccal bone plate (PBBP) at placement. METHODS: Patients where either a dehiscence defect or thin PBBP at implant placement was corrected by SPAL technique (SPALdehiscence and SPALthin groups, respectively) and patients presenting a residual PBBP thickness ≥2 mm at implant placement (control group) were retrospectively selected. The number of peri-implant sites positive to bleeding on probing (BoP) at 6 months following prosthetic loading was the primary outcome. Also, height of keratinized mucosa, marginal soft tissue level, Plaque Index, peri-implant probing depth, suppuration on probing, and interproximal radiographic bone level (RBL) were evaluated. RESULTS: Thirty-four patients (11 in the SPALdehiscence group, 11 in the SPALthin group, and 12 in the control group) were included. In each SPAL group, 10 patients (90.9%) showed peri-implant tissue thickness ≥2 mm at the most coronal portion of the implant at uncovering. The prevalence (number) of BoP-positive sites was 2, 1, and 0 in the SPALdehiscence , SPALthin , and control groups, respectively. RBL amounted to 0.3 mm in the SPALdehiscence group, 0.2 mm in the SPALthin group, and 0 mm in the control group. CONCLUSION: After 6 months of prosthetic loading, patients treated with SPAL technique show limited peri-implant mucosal inflammation in association with shallow PD and adequate KM. At implants receiving SPAL technique, however, interproximal RBL was found apical to its ideal position.

RESUMO

AIM: The aim of this prospective cohort study was to assess the effect of a pocket irrigator/evacuator device (IED) in the non-surgical treatment of peri-implantitis. MATERIAL AND METHODS: In total 24 patients having 38 implants diagnosed with peri-implantitis were included in this study. Peri-implant pockets were irrigated six times in three consecutive weeks. The primary outcome was bleeding on probing (BoP). Secondary outcome parameters included plaque index (Pl), suppuration on probing (SoP), probing pocket depth (PPD), marginal bone loss (MBL), presence and numbers of periodontal pathogens. Parameters were assessed at baseline and 3 months after the last treatment. Treatment pain perception was scored using the visual analog scale (VAS) after the first and last treatment. RESULTS: At 3 months, IED treatment revealed significant reduction of peri-implant BoP (71% [±20] vs 57% [±28] [P = .014]) and peri-implant plaque scores (10 [±14] to 5 [±9] [P = .039] [T0 vs T3 respectively]). Significant reduction in mean peri-implant PPD from 4.92 mm (SD ± 1.28) to 4.66 mm (SD ± 1.35) (P = .041) was observed. In addition, a reduction in VAS pain score between the first and the last (6th) treatment was found (P = .039). No reduction in SoP (P = .088) was found. No changes in mean periodontal full mouth plaque, BOP, SOP and PPD levels, MBL and microbiological outcomes were found. CONCLUSION: Beneficial clinical effects in terms of BoP, PPD and PI were found at 3 months after IED treatment. However, the IED does not seem to effectively treat peri-implantitis in terms of disease resolution.

RESUMO

Purpose: The purpose of this study was to determine the relative plaque reduction efficacy of powered versus manual toothbrushes in children. Methods: A systematic review and meta-analysis were conducted based on a literature search that included Medline, Embase, FDA publications, Cochrane Database of Systematic Reviews, Dentistry and Oral Science, and Berman Medical Library, Hebrew University. Studies were chosen that were randomized controlled trials and published between 1980 to 2019 in English that compared plaque reduction with manual and powered toothbrushes in children. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence. Results: From a search of 1,502 articles, nine articles were selected for meta-analysis. A statistically significant plaque reduction benefit for a powered toothbrush versus manual toothbrush (P<0.001): combined mean difference (MD) was 0.590 and the 95 percent confidence interval was 0.352 to 0.828 (random-effects model). Two tests revealed considerable heterogeneity (I² equals 96 percent; Cochran's Q, P<0.001). A low possibility of bias was indicated by Begg-Mazumdar and Egger tests (P>0.1 for both). Evidence quality was given a GRADE score of moderate. Conclusions: Powered toothbrushes were more effective than manual toothbrushes for plaque removal in children.

RESUMO

PURPOSE: To assess the safety and efficacy of three stannous fluoride (SnF2) dentifrices in the reduction of gingivitis versus a negative control dentifrice. METHODS: This was a randomized, controlled, double-blind, four-treatment parallel group study. 120 healthy adult volunteers with established gingivitis were enrolled and randomly assigned to one of four dentifrice treatment groups (30/group): 0.454% SnF2 + citrate dentifrice A; 0.454% SnF2 + sodium hexametaphosphate dentifrice B; 0.454% SnF2 + pyrophosphate dentifrice C; or 0.76% sodium monofluorophosphate negative control group. Subjects brushed with their assigned dentifrice and an assigned regular manual toothbrush (Oral-B Indicator) for 1 minute twice daily for 12 weeks. Number of gingival bleeding sites and Löe-Silness Gingival Index (LSGI) scores were assessed at baseline and at Weeks 2, 4 and 12. RESULTS: 120 subjects were enrolled and 112 completed the trial. Subjects had an average age (SD) of 39.31 (14.5) years; 67% of subjects were female. Overall baseline means (SD) were 81.2 (25.6) for number of bleeding sites and 1.51 (0.197) for mean LSGI score. Baseline disease levels were balanced across all treatment groups. At Week 2, SnF2 dentifrices A and B demonstrated a significant reduction in gingival bleeding sites versus the negative control; however, SnF2 dentifrice C was not significantly different from the negative control (P= 0.15). At Weeks 4 and 12, all SnF2 dentifrices demonstrated a significant gingival bleeding site reduction versus the negative control (P< 0.001). At Weeks 2, 4 and 12, the SnF2 dentifrices were rank ordered dentifrice A > dentifrice B > dentifrice C for reduction in gingival bleeding sites (P< 0.001). The same trends were seen for LSGI scores. CLINICAL SIGNIFICANCE: In this 12-week clinical study, all 0.454% SnF2 dentifrices delivered statistically significant reductions in the number of gingival bleeding sites relative to the negative control. Importantly, statistically significant efficacy differences were observed among the three 0.454% SnF2 dentifrices, demonstrating the important role that differences in formulation have on clinical efficacy.

RESUMO

Purpose: The purpose of this study was to evaluate the effects of using mobile text messages and a novel floss holder as compared to finger flossing or the novel floss holder alone, on the psychological, behavioral, and clinical parameters of patients with gingivitis.Methods: A total 165 adults were assessed for eligibility and 144 met the criteria for randomization into three groups: Finger Floss (FF, n=43), Novel Floss Holder (NFH, n= 40), and Novel Floss Holder plus Text Messages (NFH+TM, n= 61) following a dental hygiene consultation appointment. Gingival bleeding points were measured on probing (BOMP) at baseline and four months later by a calibrated dental hygienist, blinded to the experimental groups. Participants also self-reported their oral hygiene behaviors, and indicated psychological determinants of behavior change prior to the dental hygiene consultation and at four months. Descriptive statistics and repeated measures analysis of variance (ANOVA) were used to compare groups over time.Results: Two subjects dropped out of the study making the total number of participants 142. At the four month follow-up, the NFH group and the NFH+TM groups demonstrated significantly higher levels of self-reported flossing, action self-efficacy, intention, action planning, and action control. The NFH+TM group showed lower levels of bleeding and higher levels of oral hygiene and recovery self-efficacy than the other groups, in addition to higher levels of maintenance self-efficacy as compared to the FF group.Conclusions: The use of a novel floss holder, NFH, was shown to improve the behavioral and psychological determinants of periodontal health four months after introduction of the device. However the clinical measures of BOMP only improved significantly when used in conjunction with text messages (NFH+TM). The use of a consciousness awareness technique,TMs, in combination with a novel device, may help patients to reach therapeutic objectives and contribute to the management of periodontal pathologies such as gingivitis.
