Influence of active reminders on oral hygiene compliance in orthodontic patients

Patient adherence in orthodontics: a scoping review

BACKGROUND

Patient adherence is a key factor in achieving orthodontic treatment success. Despite an evolution in orthodontic healthcare, no recent comprehensive reviews are available on patient adherence in orthodontics. This scoping review provides an evidence-based overview of the literature available on multiple aspects of patient adherence in orthodontics, during both active treatment as well as during the retention phase. Knowledge gaps identified in the literature are listed.

METHODS

The protocol for this scoping review was registered in the Open Science Framework ( https://doi.org/10.17605/OSF.IO/EC6QD ). Electronic databases and reference lists of relevant studies were searched up to 9 February 2023. The inclusion criteria were studies investigating any form of patient adherence in orthodontics published in English from 2006 onwards. The exclusion criteria were studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist's recommendations and advice, those with oral cleft and craniofacial conditions, and those treated solely for obstructive sleep apnoea. Non-peer-reviewed studies and case reports were also excluded.

RESULTS

A total of 3284 articles were identified, 60 of which met the criteria for final inclusion.

CONCLUSIONS

There is no conclusive evidence on which factors have a significant impact on patient adherence and how patient adherence can be promoted. The degree of patient adherence is generally not compared to achieved treatment results or stability of treatment results, making it difficult to provide clear statements about the impact of the degree of adherence on desired treatment results or orthodontic stability.

The effect of text message reminders on compliance with Twin Block appliances: A randomised controlled trial

AIMS

The aim of this study was to evaluate whether text reminders influence patient compliance with Twin Block appliances. The null hypothesis was that there was no statistically significant differences in Twin Block compliance between those who receive text reminders and those that do not.

DESIGN

Single-blind parallel randomised controlled clinical trial.

SETTING

Health Service Executive (HSE) orthodontic outpatient clinic in Dublin, Ireland.

PARTICIPANTS

A total of 59 patients aged 11-15 years with a 5a Index of Orthodontic Treatment Need (IOTN grade) starting treatment with Twin Block appliances.

METHODS

A computer-generated unstratified allocation sequence was used to randomise the participants into the control group (CG) or the text group (TG). Both groups were asked to wear their appliances full-time. In addition to the same verbal and written instruction received by the CG, the TG received text message reminders, every 3 days, to wear their appliances. The primary outcome measure was wear time reported by Theramon® sensors embedded in the appliances. Data on wear time were uploaded from the Theramon® sensors onto cloud software. Participants in both groups were asked to fill out wear diaries and submit these at each visit. Treating clinicians and the primary investigator were blinded to the allocation group. Participants were followed up for 4 months. Participants were not blinded to their treatment group.

RESULTS

In total, 29 participants were allocated to the CG and 30 to the TG. The data for 53 participants were analysed, 24 from the CG and 29 from the TG. The median hours/day of wear recorded using the Theramon® sensors was 13.77 (interquartile range [IQR] = 10.19) for the CG and 17.72 (IQR = 5.62) for the TG. The difference in wear time recorded was not statistically significant (P = 0.16).

CONCLUSION

The study concluded that text message reminders had no statistically significant influence on patient compliance with Twin Block appliances.

Assessing effectiveness of WhatsApp messaging program in oral hygiene care for orthodontic patients: A randomised controlled trial

OBJECTIVE

To evaluate the difference in the oral hygiene status of participants with fixed appliances between a 'weekly WhatsApp application oral hygiene message reminders' trial group and a 'verbal instructions' control group over a follow-up duration of 12 weeks.

DESIGN

Prospective, single-blind, randomised controlled trial with an allocation ratio of 1:1 over a 12-week follow-up.

SETTING

Government Orthodontic Unit, Raub Dental Clinic, Raub, Pahang, Ministry of Health, Malaysia.

PARTICIPANTS

A total of 40 patients aged 13-25 years undergoing orthodontic treatment with fixed appliances.

METHODS

The 40 patients were recruited and randomly allocated to a control (n = 20) or trial group (n = 20). Participants in the trial group received weekly oral hygiene reminders via the WhatsApp application for 12 weeks, while the control group did not receive any reminders. The primary outcome was oral hygiene, which was measured by the single-blinded examiner using the Orthodontic Plaque Index (OPI) at three orthodontic check-ups: baseline (T0); 6-week follow-up (T1); and 12-week follow-up (T2).

RESULTS

The mean age was 17 years, and 80% were female patients. At the end of the 12-week follow-up, improvements in OPI scores were observed, regardless of the intervention. At T2, the median OPI score for the trial group (n = 20) was 0 (interquartile range [IQR = 0) while that for the control group (n = 20) was 2 (IQR = 0). A Mann-Whitney U test revealed a statistically significant difference (P <0.05), with effect size r = 0.87 between the control and trial groups, whereby the latter witnessed marked improvement in OPI throughout the visits. No harms or adverse effects occurred in this trial.

CONCLUSION

The short-term findings demonstrated that participants receiving regular reminders of oral hygiene via WhatsApp messaging had a significant improvement in oral hygiene compared to the control group.

Efficacy of a mobile phone application for the improvement of oral hygiene of patients undergoing fixed orthodontic treatment : A randomized controlled clinical trial

OBJECTIVES

This study aimed to assess the efficacy of a mobile phone application (app) to improve oral hygiene of patients undergoing fixed orthodontic treatment.

MATERIALS AND METHODS

This randomized controlled clinical trial was conducted with a total of 60 patients undergoing fixed orthodontic treatment in two groups: intervention and control (n = 30 each). A previously designed mobile app (Labkhand) was used by patients in the intervention group. Orthodontic plaque index (OPI) and modified gingival index (MGI) were recorded in the two groups at baseline (first session or T0), and after 1 (T1) and 3 (T2) months. The number of debonded/broken brackets was also recorded, and pain score of the patients was assessed at nine time points. Data were analyzed using the χ2 test, paired t‑test, and repeated measures analysis of variance (ANOVA; α = 0.05).

RESULTS

The two groups demonstrated no significant difference in OPI and MGI at T0 (P > 0.05). OPI and MGI at T1 and T2 were significantly lower in the intervention group than in the control group (P < 0.05). The number of patients with broken brackets in the intervention group was significantly lower than that in the control group (P = 0.017). The two groups reported no significant difference in pain score (P > 0.05).

CONCLUSION

The Labkhand mobile app successfully improved oral hygiene indices of patients undergoing fixed orthodontic treatment, and decreased the frequency of broken brackets after 1 and 3 months of use.

Mobile app for comprehensive management of orthodontic patients with fixed appliances : Design and use

OBJECTIVES

This study aimed to design and implement a mobile phone application (app) aiming to enhance the cooperation and oral hygiene of orthodontic patients.

METHODS

An orthodontic app named "Labkhand" was designed by a team of orthodontists and programmers according to the needs and scheduled interventions for patients. The aim of this app was to obviate the orthodontic needs of patients by providing educational content in the form of texts and videos, oral hygiene reminders, appointment reminders, and nutrition reminders. It also enabled instant messaging and chatting between patients and dental personnel. In this study, 61 patients were monitored during their orthodontic treatment procedure. All patients were evaluated using a questionnaire with 7 questions before and after a 6-month treatment period. A total of 31 patients were instructed to use the app, while the other 30 patients received treatment without the app. The collected data were analyzed using paired t‑test and analysis of covariance (ANCOVA) test.

RESULTS

While the control group's questionnaire score remained almost the same (P > 0.05), the mean questionnaire score of patients in the intervention group significantly increased after using the app compared to the baseline scores acquired before using the app (P < 0.001). The greatest improvement was noted in topics related to "reminding of appointments", "general information about orthodontic treatment", and "oral hygiene maintenance and instructions". "Quality of services" and "patient-orthodontist communication" showed the least improvement in patient satisfaction.

CONCLUSIONS

The Labkhand orthodontic app has multiple functions and can obviate the needs of orthodontic patients easily and at a low cost.

Influence of Reminder on Enhancing Compliance in Patients with Fixed Orthodontic Appliance Treatment (a Randomized Controlled Clinical Trial)

Purpose

Patient compliance during orthodontic treatment has a significant effect on the aims, outcome, and duration of the treatment. The aim of this study is to evaluate the influence of reminders on enhancing orthodontic patient compliance.

Patients and Methods

Twenty-six subjects undergoing orthodontic treatment with fixed appliances were randomly assigned into two groups: control (Ct) and intervention (In) groups. The oral hygiene parameters of plaque index (PI), bleeding index (BI), and white spot lesion (WSL) with appointment adherence and bracket fracture were recorded at base line (T0), 2 months (T1), 4 months (T2), and 6 months (T3). In group participants received weekly reminders and subjects' compliances were classified into poor, fair, and excellent compliance.

Results

Statistically significant differences were found in PI level at T2 between Ct and In groups (p-value = 0.006), whereas a non-significant difference was found for BI (p-value>0. 05). There was a statistically significant increase in WSL for the Ct group across the study time points (p-value = 0.03), while no significant change in WSL was detected for the In group (p-value>0.05). The compliance levels of In and Ct groups were excellent and fair, respectively.

Conclusion

The study suggests that weekly reminders can enhance the oral hygiene status in patients with orthodontic appliances (POA) and elevate the level of compliance to excellent.

Knowledge, attitude and practice of patients towards orthodontic treatment

BACKGROUND

Orthodontic treatment is a time-consuming and highly technique-sensitive clinical procedure. A patient's comprehension and compliance with oral hygiene instructions and appliance maintenance are critical to the success of orthodontic treatment. This study was performed to assess the knowledge, attitude and practice of patients seen at government orthodontic clinics in the Federal Territories of Kuala Lumpur and Putrajaya towards orthodontic treatment.

METHODS

A validated, bilingual, self-administered questionnaire comprising fifteen questions across the domains of Knowledge, Attitude and Practice was used and responses were assessed with 3 responses; one correct, one incorrect and one reflecting uncertainty. 507 patients from five orthodontic centres participated in this study. Data was analysed using SPSS. Continuous data was summarised as mean and standard deviation or median and inter-quartile range, as appropriate. Categorical data was summarised as frequency and percentage, then univariable analysis was carried out with Pearson's chi-square test or Fisher's exact test, as appropriate.

RESULTS

The mean age of respondents was 22.5 years (SD ± 2.8). A majority of respondents were female (64.1%) and from the lowest income bracket or B40 group (71%). Overall, for the knowledge domain, a majority of the respondents got all questions correct. 69.4% of patients were aware that incomplete treatment could lead to worsening of their malocclusion. 80.9% of respondents were aware of the need for a retainer upon completion of their orthodontic treatment. For the attitude section, 64.7% felt that they had to wait a very long time to see the orthodontist. In the Practice domain, the majority only got two of the five questions correct. Only 39.8% of respondents made an effort to alter dietary habits all of the time. In general, females and those with tertiary education fared better for all three domains.

CONCLUSIONS

The orthodontic patients in the Federal Territories of Kuala Lumpur and Putrajaya possess good knowledge about their treatment however their attitude and orthodontic related practices need to be improved.

White Spot Lesions (WSLs)-Post-Orthodontic Occurrence, Management and Treatment Alternatives: A Narrative Review

Although treatment with fixed or mobile appliances has become an important part of modern orthodontics, side effects such as white spot lesions (WSLs) have a negative impact on the aesthetic outcome of orthodontic treatment. The purpose of this article was to review current evidence on the diagnosis, risk assessment, prevention, management and post-orthodontic treatment of these lesions. Data collection was performed electronically, and the initial search using the keywords "white spot lesions", "orthodontics", "WSL", "enamel" and "demineralization" in different combinations resulted in 1032 articles for the two electronic databases used. Ultimately, a total of 47 manuscripts were considered relevant to the aim of this research and included in this review. The results of the review indicate that WSLs remain a significant problem during orthodontic treatment. According to studies in the literature, the severity of WSLs correlates to the duration of treatment. Using toothpaste with more than 1000 ppm fluoride at home reduces the frequency of WSL separation and regular application of varnishes in the office reduces the frequency of the occurrence of WSLs only in the context of maintaining a strict hygiene regime. The old hypothesis that elastomeric ligatures retain more dental plaque than metal ones has been refuted. There are no differences in the appearance of WSLs between conventional brackets and self-ligating brackets. Clear aligner mobile devices develop fewer WSLs but are more extensive as opposed to conventional fixed devices, while lingual orthodontic appliances have a lower incidence of WSLs, and the most effective device for preventing these lesions is WIN, followed by Incognito.

Effectiveness of Smart Applications of Oral Hygiene Instructions on Periodontal Health Compared to Oral Information: A Prospective Study

Nowadays, smartphone applications are widely used in different areas of life, including medical science. The present study aimed to assess the effectiveness of a smartphone application of oral hygiene instructions (OHI) on periodontal health compared to the traditional chairside OHI. All the participants (n = 39) were divided into two groups: control group and test group. Participants of the control group were given verbal OHI and participants of the test group were asked to use a smartphone application to upkeep their oral habits. The gingival index (GI) and Quigley-Hein Turesky modification index (QHTMI) were used for scoring the plaque accumulation at baseline and after one month of the periodontal treatment. A paired t-test and an independent t-test were performed to compare the mean of GI and QHTMI between intra-group and inter-group, respectively. The paired t-test showed significant differences in GI and QHTMI improvement after one month in both groups. Moreover, the independent t-test showed no significant differences between the two groups. However, the test group showed a lower mean score in GI and QHTMI assessments compared to the control group. Smartphone applications in oral health applications did not exhibit any superiority in periodontal health over the traditional OHI method in the current study.

Effect of electronic reminders on patients' compliance during clear aligner treatment: an interrupted time series study

Patient compliance is relevant to achieving therapeutic goals during clear aligner therapy (CAT). The aim of this study was to evaluate the efficacy of remote electronic (e-)reminders and e-feedback on compliance during CAT using an interrupted time series (ITS) analysis. We used routinely collected mobile application data from a German healthtech company (PlusDental, Berlin). Our primary outcome was self-reported compliance (aligner wear time min. 22 h on 75% of their aligners were classified as fully compliant, min. 22 h on 50–74.9% of their aligners: fairly compliant; min. 22 h on < 50% of their aligners: poorly compliant). E-reminders and e-feedback were introduced in the 1st quarter of 2020. Compliance was assessed at semi-monthly intervals from June-December 2019 (n = 1899) and June-December 2020 (n = 5486), resulting in a pre- and post-intervention group. ITS and segmented regression modelling were used to estimate the effect on the change in levels and trends of poor compliance. Pre-intervention, poor compliance was at 24.47% (95% CI: 22.59% to 26.46%). After the introduction of e-reminders and e-feedback (i.e., post-intervention), the percentage of poorly compliant patients decreased substantially, levelling off at 9.32% (95% CI: 8.31% to 10.45%). E-reminders and e-feedback were effective for increasing compliance in CAT patients.

Clinical Significance: Orthodontists and dentists may consider digital monitoring and e-reminders to improve compliance and increase treatment success.

Motivation of Adult Patients with Orthodontic Treatment in Maintaining Oral Hygiene

Background: In the last decades, adult patients require orthodontic treatment as a therapeutic method in an increasing percentage. This treatment has a lot of benefits, but unfortunately it also presents a number of complications and risks, among which favoring the accumulation of bacterial plaque is the most concerning.

Aim of the study: In this study we aimed to evaluate the effectiveness of using the dark-field microscope as a method of motivating adult patients with orthodontic treatment in maintaining a proper oral hygiene.

Material and methods: Thirty-six patients were selected based on the inclusion and exclusion criteria. At time T0, patients were divided into two groups: Group 1–microscope and Group 2 – control, in such a way that the groups were as homogeneous as possible. Dental plaque samples were collected and analyzed under a dark field microscope in the presence of the patient for subjects from Group 1 but not Group 2. All patients were then instructed on oral hygiene techniques. The following periodontal indices were recorded of each patient: plaque index (PI), index of bleeding on probing (BOP), probing depth (PD) – at T0 and T1 (after one month).

Results: Comparing the PI and BOP values before (T0) and after treatment (T1), statistically significant results were detected (PI: p = 0.0020, BOP: p = 0.0297), which denotes that patients who observed the bacterial load of their dental plaque in real time using the dark-field microscope had a better oral hygiene and lower values of periodontal health indices. Regarding the PD index, the difference between time T0 and T1 was not statistically significant (p = 1.4762).

Conclusions: During the orthodontic treatment, adult patients often present gingival inflammation caused by improper hygiene. The use of the dark-field microscope is effective in motivating patients regarding the rules of maintenance of a proper oral hygiene.

Gingival recession in mandibular anterior teeth in patients with Class II malocclusion treated with elastics and Twin Force appliance

INTRODUCTION

This study aimed to compare the early results of gingival recession in patients with Class II malocclusion treated with Class II intermaxillary elastics and the Twin Force appliance.

METHODS

The sample comprised 55 patients with Class II malocclusion treated without extraction and divided into 2 groups. Group 1 consisted of 23 patients treated with fixed appliances and Class II elastics, with mean initial age of 15.41 ± 5.65 years and a mean treatment time of 3.11 ± 0.91 years. Group 2 consisted of 32 patients treated with fixed appliances and the Twin Force mandibular protraction appliance, with a mean initial age of 18.45 ± 6.63 years and a mean treatment time of 3.17 ± 1.59 years. Dolphin software measured gingival recession in initial and final intraoral photographs. Initial and final lateral cephalograms were used to measure the position of the mandibular incisors. Intragroup and intergroup comparisons were performed by dependent and independent t tests, respectively.

RESULTS

In both groups, there was no significant increase in gingival recession with orthodontic treatment, and there was significant protrusion and buccal inclination of the mandibular incisors. When changes with treatment were compared between the groups, there was no statistically significant difference in gingival recession and mandibular incisor position.

CONCLUSIONS

There was no significant increase in gingival recession immediately after orthodontic treatment performed with intermaxillary elastics and the Twin Force appliance.

Concerns of orthodontic patients during the COVID-19 quarantine period

Introduction:

Quarantine protocols for coronavirus disease 2019 (COVID-19) pandemic has modified orthodontic appointments.

Objective:

to evaluate self-reported experience and needs of orthodontic patients during the quarantine period without in-person appointments.

Methods:

Thirty patients, aged 8 to 21 years, under active orthodontic treatment were randomly selected. A phone call questionnaire including questions on physical and emotional impacts of the quarantine of COVID-19 was applied during the second month of Brazilian quarantine.

Results:

Sixteen percent of the patients reported pain related to the orthodontic appliance. Appliance breakage was observed in 23.33%. Twenty percent felt the need of an emergency orthodontic appointment and 3.33% visited a private practice. Moreover, 23% reported that even in an emergency need, they would not search for an appointment, preferring to communicate with the orthodontist by WhatsApp. Oral hygiene self-perception status showed improvement in 36.67% and worsening in 6.67% of the patients, while 56.66% reported maintenance of the same hygiene status. Sixty percent were concerned about the orthodontic treatment. General concerns were primary related to health and a possible extension of the quarantine time.

Conclusions:

During COVID-19 quarantine, orthodontic patients demonstrated a low frequency of orthodontic appliance interference in daily life, and most of them reported a maintenance of oral hygiene habits. The frequency of appliance related pain and breakage was 16.67% and 23.33%, respectively. Patients’ main concern during the quarantine period was the fear of getting sick and the uncertainness about the extension of the quarantine period.

Influence of Multimedia Reminders on Oral Hygiene Status During Removable Orthodontic Treatment: A Randomized Controlled Trial

Introduction:

Orthodontic appliances complicate daily oral hygiene maintenance and enhance the formation of microbial biofilm on tooth surfaces and orthodontic appliances.

Objective:

This trial was conducted to assess the effect of reminders on oral hygiene of patients during removable orthodontic treatment.

Methods:

In this 2-arm parallel randomized controlled trial, 66 orthodontic patients with removable maxillary appliance were randomly allocated with 1:1 ratio to message reminders and the control group. The patients in the messaging group received one or two message reminders and educational videos weekly during the course of treatment. A single blinded examiner measured the plaque index (PI), gingival index (GI), and dental caries index of patients in both groups at baseline (T0) and one (T1), three (T2), and six (T3) months after the first day of treatment to assess their oral hygiene status during treatment.

Results:

A total of 30 patients in control group and 28 in reminder group completed the study. The PI and GI scores were increased neither in control group nor in message reminder group during T0 and T1, significantly. The PI and GI scores in message reminder group were significantly lower than those in the control group at T2 (PI: P = 0.001, GI: P = 0.003) and T3 (PI: P = 0.024, GI: P = 0.022). Slight significant increasing in the PI and GI score were found during T2 and T3 in message reminder group. Caries index showed no significant difference between two groups during study.

Conclusion:

It seems that reminders can efficiently promote oral hygiene of patients undergoing removable orthodontic treatment.

The effectiveness of a bespoke mobile application in improving adherence with removable orthodontic retention over 12 months: A randomized controlled trial

INTRODUCTION

The primary aim was to analyze the effect of providing a mobile application (My Retainers) on adherence with removable retention.

METHODS

Eighty-four participants planned for thermoplastic retainers were randomly allocated to 2 groups. The intervention group was given access to a bespoke mobile application, while the control group was not given access. Baseline data were obtained at the removal of orthodontic appliances with follow-up at 3 months, 6 months, 9 months, and 12 months. The primary outcome was objectively assessed retainer wear recorded using a TheraMon microelectronic sensor (MC Technology GmbH, Hargelsberg, Austria). Secondary outcomes were stability and periodontal implications.

RESULTS

The objectively assessed wear time at 12 months was low in both groups, being marginally higher in the intervention (median, 3.09 h/d; interquartile range, 8.1) than the control group (median, 1.44 h/d; interquartile range, 9.22) with no between-group statistical difference (P = 0.30, 95% confidence interval [CI], -3.91 to 1.19). No statistically significant difference was identified between the groups in terms of stability and periodontal outcomes. Improvement in plaque scores (P <0.0001; 95% CI, -0.20 to 0.15) and bleeding on probing (P <0.0001, 95% CI, -0.23 to -0.12) was noted over time with no periodontal attachment loss detected over the study period.

CONCLUSIONS

Provision of the mobile application did not lead to improved adherence with thermoplastic retainer wear. Similarly, no benefit in respect of either occlusal stability or periodontal health was observed over the 12-month study period. Further novel approaches to improve adherence with retainer wear and oral hygiene measures are required.

Benefits of Using Fluorescence Induced Theragnosis in Fixed Orthodontic Therapy: Status, Technology and Future Trends

Dental biofilm is often found to be the source of bacteria that releases toxins, peptides, lipopolysaccharides as well as organic acids, which lead to gingival inflammation and tooth caries. Further, the persistent plaque may result in the continued destruction of the surrounding soft and hard tissues. During fixed orthodontic therapy, arch-wires, brackets, and elastic modules have been shown to be sites of significant plaque accumulation, making it difficult for a patient to maintain proper oral hygiene. The problem most dentists face is that they cannot visualize this biofilm completely to be able to carry out efficient plaque removal. Visual assessment is, to date, the most common method for plaque visualization, and various indexes have been demonstrated to be sufficient for quantification of the amount of plaque present. However, the problem is that visual assessments are inconsistent, operator dependent and often subjective, which can lead to inconsistency in results. Fluorescence is one such method that can be explored for its use in effective plaque identification and removal. Literature has it that dentists and patients find it particularly useful for monitoring oral hygiene status during treatment. Fluorescence has the capability of offering clinical orthodontists and researchers a new method of detection of demineralization during orthodontic treatment, furthermore, for efficient removal of orthodontic adhesive cements, fluorescent light may be used in conjunction with high-speed burs to deliver fast, less time consuming, and safer results. The benefit of direct visual treatment using fluorescence enhanced theragnosis is that the patient receives controlled and guided therapy. It has multiple benefits, such as early diagnosis of caries, biofilm identification, and even helps to achieve improved treatment outcomes by better resin selection for esthetic procedures.

Influence of WhatsApp and electronic mail reminders on oral hygiene compliance of orthodontic patients using planimetry : A randomized clinical trial

PURPOSE

To determine the effect of WhatsApp (Facebook Inc., Menlo Park, CA, USA) and electronic mail reminders on oral hygiene compliance of orthodontic patients.

METHODS

A randomized, parallel group, double blinded study was conducted on 54 patients undergoing orthodontic treatment at a university clinic. They were randomized to 3 groups, i.e., WhatsApp (W) group, electronic mail (email) (E) group and control (C) group with 18 subjects in each group. Group (W) and group (E) received oral health messages once a week through WhatsApp and email reminders, respectively, while group (C) did not receive any reminders. Plaque was measured at baseline (T0), after 4 weeks (T1), and after 8 weeks (T2). For each subject, intraoral photographs were taken after application of a plaque-disclosing agent; and the area covered by plaque was measured on teeth 12, 13, 43, 22, 23 and 33 by planimetry. Data were analyzed using SPSS (version 22, IBM Corp., Armonk, NY, USA). Mixed analysis of variance (ANOVA) was used to compare plaque scores between and within the groups.

RESULTS

A total of 54 subjects (14 males and 40 females) with mean age of 22.43 years completed the study. At the end of 8 weeks, no statistically significant difference in the mean plaque score was found between the groups at the different time intervals (p = 0.201).

CONCLUSION

WhatsApp and email reminders did not significantly influence the oral hygiene compliance of orthodontic patients.

Teledentistry and mHealth for Promotion and Prevention of Oral Health: A Systematic Review and Meta-analysis

The dental profession has experienced a dramatic acceleration in the use of communication systems and information-based technologies over recent years, originating new paradigms for the prevention and promotion of oral health. The purpose of this systematic review was to determine the effect of teledentistry-based (telematic) strategies, reported in randomized controlled trials and quasi-randomized trials, with a focus on oral health prevention and promotion-related outcomes in patients of all ages. We searched Medline via PubMed, SCOPUS, and Web of Science from inception until August 2020, regardless of the language of publication. We selected studies for inclusion and conducted data extraction, assessed risk of bias (Cochrane tool), and evaluated the certainty of the evidence (GRADE approach) in duplicate and independently. Out of 898 potentially eligible references, we selected 43 for full-text screening, of which 19 studies proved eligible: 18 randomized controlled trials and 1 quasi-randomized study. Virtual interventions were mostly asynchronous via apps (n = 9), text messages (n = 9), or computer-aided learning (n = 1). The use of teledentistry as compared with conventional strategies may result in a large reduction in the plaque index (standardized mean difference, -1.18; 95% CI, -1.54 to -0.82; I² = 92%; low certainty) and will likely result in a large reduction in the gingival index (standardized mean difference, -2.17; 95% CI, -3.15 to -1.19; I² = 97%; moderate certainty) and in the incidence of white spot lesions (risk ratio, 0.48; 95% CI, 0.35 to 0.66; I² = 0%; moderate certainty), with an increased effect over time. Evidence suggests that teledentistry, particularly mHealth (messages and apps), is a promising clinical tool for preventing and promoting oral health, especially under the accelerated virtualization of dentistry. Future studies should include a broader spectrum of the population, including adults and elders, to better inform policy and implementation of teledentistry (PROSPERO: CRD42020192685).

Effectiveness of three different types of educational methods on implementation of proper oral hygiene behaviour prior to orthodontic treatment

Objective:

The aim of this study was to compare three teaching methods’ time and personnel requirements, and their effects on plaque and gingival indices.

Methods:

This study was a single-blind randomized controlled trial on fixed orthodontic appliance candidates (n = 90), assigned into a control group (n = 30) and two different study groups (n = 30 each). The control group received standard printed educational material and was assisted with verbal information. The study groups either received video-assisted or hands-on training about fixed orthodontic appliance and oral hygiene. The time requirements for all three educational interventions was recorded during the initial visit. The adequacy of oral hygiene was documented through plaque and gingival indices during the initial visit and eighth week of the treatment. The continuous variables were analyzed using 1-way ANOVA. Tukey HSD and Student t-tests were used for post-hoc comparisons (α?#8197;= 0.05). Also, a chi-square test was used for the analysis of categorical variables.

Results:

Standard education failed to maintain the plaque and gingival indices at the eighth week of the treatment. Although both video-assisted and hands-on training took a considerable amount of time, they served well in preserving both of the indices at the eighth week. The longer the educational intervention was, the better the preservation of the plaque and gingival indices.

Conclusion:

Educational intervention, either with video-assisted or hands-on programs, provided better results in oral hygiene depending on the time and personnel constraints of the orthodontist.

Traditional vs digital communication channels for improving compliance with fixed orthodontic treatment

OBJECTIVES

To compare the efficacy of traditional and digital communication strategies in improving compliance with fixed orthodontic therapy and to investigate the effect of gender, baseline oral hygiene habits, socioeconomics, and parents' education on orthodontic compliance.

MATERIALS AND METHODS

Orthodontic patients were randomly allocated to three groups. Group 1 received traditional communication including verbal and written instructions, whereas group 2 and group 3 received, in addition to traditional communication, weekly text messages or e-mails with audiovisual links, respectively. Baseline demographics (age, gender, baseline oral hygiene habits, socioeconomics, and parents' education) as well as compliance indicators (treatment duration, failed appointments, incidence and total number of appliance breakages) were recorded. For statistical analysis, Pearson chi-square, independent t-test, and one-way analysis of variance were used (P < .05).

RESULTS

Of 120 patients (aged 12 to 18 years) recruited, 108 completed the trial (G1 = 37, G2 = 35, G3 = 36). Weekly text messages failed to improve patient compliance. On the other hand, sending weekly e-mails with audiovisual links significantly (P = .014) reduced the incidence of appliance breakage as compared with the control group. Females had a significantly lower incidence of breakage (P = .041) and a fewer total number of breakages (P = .021). Patients from households with high income had significantly better compliance (P < .05). A higher level of parents' education was significantly associated with a lower incidence and total number of breakages (P < .01).

CONCLUSIONS

Communication with patients using link-rich e-mails and reminders could improve patient compliance with fixed orthodontic treatment. Female patients, high household income, and high parent education are associated with better compliance with fixed orthodontic treatment.

Microtask Detection

Information systems, such as task management applications and digital assistants, can help people keep track of tasks of different types and different time durations, ranging from a few minutes to days or weeks. Helping people better manage their tasks and their time are core capabilities of assistive technologies, situated within a broader context of supporting more effective information access and use. Throughout the course of a day, there are typically many short time periods of downtime (e.g., five minutes or less) available to individuals. Microtasks are simple tasks that can be tackled in such short amounts of time. Identifying microtasks in task lists could help people utilize these periods of low activity to make progress on their task backlog. We define actionable tasks as self-contained tasks that need to be completed or acted on. However, not all to-do tasks are actionable. Many task lists are collections of miscellaneous items that can be completed at any time (e.g., books to read, movies to watch), notes (e.g., names, addresses), or the individual items are constituents in a list that is itself a task (e.g., a grocery list). In this article, we introduce the novel challenge of microtask detection, and we present machine-learned models for automatically determining which tasks are actionable and which of these actionable tasks are microtasks. Experiments show that our models can accurately identify actionable tasks, accurately detect actionable microtasks, and that we can combine these models to generate a solution that scales microtask detection to all tasks. We discuss our findings in detail, along with their limitations. These findings have implications for the design of systems to help people make the most of their time.

Effectiveness of metronidazole gel and mobile telephone short-message service reminders on gingivitis in orthodontic patients

OBJECTIVES

To compare the effectiveness of metronidazole gel and mobile telephone short-message service (SMS) reminders on gingivitis in patients undergoing fixed orthodontic treatment.

MATERIALS AND METHODS

The trial was double blinded (patient and investigator), and only the clinical trial unit pharmacist was unblinded. Data were collected from patients undergoing fixed orthodontic treatment for at least 6 months. A total of 66 patients were randomly assigned to either 0.8% metronidazole gel (n = 22), SMS reminder and placebo gel (n = 22), or placebo (control) group only (n = 22). Gingival index (GI), bleeding index (BI), and orthodontic plaque index (OPI) were evaluated on several teeth at baseline (T0) and after 4 weeks (T1). Paired-sample t-tests were used to compare mean differences of indexes at T0 and T1 in the groups, and independent-sample t-tests were used to determine the effects of interventions compared with the controls.

RESULTS

Data from 64 patients were analyzed; there were 2 dropouts. There were statistically significant (P < .05) reductions in GI, BI, and OPI scores from T0 to T1 for each intervention. However, there were no significant differences between each intervention and the control group. There were no adverse effects.

CONCLUSIONS

The null hypothesis could not be rejected. There is no difference between interventions (application of 0.8% metronidazole gel and SMS reminder for reinforcing oral hygiene) in reducing gingival inflammation in orthodontic patients.

Outcomes of clear aligner treatment with and without Dental Monitoring: A retrospective cohort study

INTRODUCTION

The effects of Invisalign clear aligner treatment with and without Dental Monitoring (DM) were compared for treatment duration, number of appointments, refinements and refinement aligners, and accuracy of Invisalign in achieving predicted tooth positions (aligner tracking). The null hypothesis was that there are no differences between Invisalign with and without DM in these parameters.

METHODS

A sample of 90 consecutively treated Invisalign patients (45 control, 45 DM) fitted the inclusion and exclusion criteria. Treatment duration, number of refinements, number of refinement aligners, time to first refinement, number of appointments, number of emergency visits, and accuracy of predicted tooth movement were observed for differences.

RESULTS

The 2 groups were homogeneous (P >0.05) for sample size, age, gender, Angle classification, maxillary and mandibular irregularity index, and the number of initial aligners. There was a significant (P = 0.001) reduction in the number of appointments by 3.5 visits (33.1%) in the DM group. There was also a significant (P = 0.001) reduction in the time to the first refinement (1.7 months) in the DM group. Compared with Invisalign predicted tooth positions, actual tooth positions were statistically (P <0.05) more accurate for the DM group for the maxillary anterior dentition in rotational movements and mandibular anterior dentition for buccal-lingual linear movement. Invisalign therapy without DM was closer to predicted tooth positions for the maxillary posterior dentition for the tip. None of these differences surpassed the clinically significant thresholds (>0.5 mm or >2°); however, the DM group achieved this in 1.7 fewer months.

CONCLUSIONS

DM with Invisalign therapy resulted in a reduced number of appointments by 3.5 visits (33.1%). The DM group also achieved a clinically similar accuracy in obtaining predicted tooth movements compared with the control group in 1.7 fewer months, indicating improved aligner tracking in the DM group.

The Effect of Chairside Verbal Instructions Matched with Instagram Social Media on Oral Hygiene of Young Orthodontic Patients: A Randomized Clinical Trial

Objective: To investigate the effectiveness of Instagram in improving oral hygiene compliance and knowledge in young orthodontic patients compared to traditional chairside verbal instructions. Design: Single-center, parallel, randomized controlled trial. Setting: Section of Dentistry of University of Pavia. Participants: 40 patients having fixed appliances in both arches were recruited and randomly divided into an intervention (n = 20) and a control group (n = 20). Intervention: At a first appointment, both groups were given verbal instructions and motivated to oral hygiene. In addition, multimedia contents on Instagram were sent weekly to trial participants for six months. Main outcome measures: For all participants, the bleeding index (BI), modified gingival index (MGI), and plaque index (PI) were assessed at baseline (T0), after one (T1), three (T2), and six months (T3). A questionnaire was administered at the beginning (T0) and at the end of the study (T3) to assess participants’ knowledge. Results: In both groups, BI, MGI, and PI significantly decreased (p < 0.05) at T1 (means control group: BI 0.26 ± 0.22, MGI 0.77 ± 0.36, PI 0.53 ± 0.20; means test group: BI 0.24 ± 0.22, MGI 0.65 ± 0.46, PI 0.49 ± 0.21) compared to baseline (means control group: BI 0.56 ± 0.27, MGI 1.23 ± 0.41, PI 0.87 ± 0.23; means test group: BI 0.54 ± 0.26, MGI 1.18 ± 0.39, PI 0.93 ± 0.20) but no significant differences in clinical measures were showed between T1, T2, and T3 (p > 0.05) (intragroup differences). Trial patients demonstrated significant improvements in knowledge with respect to controls comparing scores at T0 and T3 (p < 0.05) but despite this result in the test group clinical outcomes did not report significant intergroup differences at any time (p > 0.05). Conclusions: Presenting multimedia information through Instagram resulted in a significant improvement in knowledge. Therefore, this social media represents an aid to the standard verbal motivation performed by orthodontists towards young patients under an orthodontic treatment.

Smartphone application-assisted oral hygiene of orthodontic patients: a multicentre randomized controlled trial in adolescents

OBJECTIVE

The aim of this trial was to test whether the use of a smartphone application (app) connected to a toothbrush improves the oral hygiene compliance of adolescent orthodontic patients.

DESIGN

The study was designed as a multicentre, randomized, controlled clinical trial.

SETTING

Two academic hospitals.

ETHICAL APPROVAL

The study was approved by the ethics committee.

SUBJECTS AND METHODS

This multicentre randomized controlled trial was conducted on 38 adolescents aged 12-18 years with full-fixed orthodontic appliances. Participants were randomly assigned either to a test group that used an interactive oscillating/rotating electric toothbrush connected to a brushing aid app or to a control group that used an oscillating/rotating electric toothbrush alone. At baseline, all patients received verbal and written oral hygiene instructions.

OUTCOME MEASUREMENTS

Data collection was performed at T1 (baseline), T2 (6 weeks), T3 (12 weeks) and T4 (18 weeks-end of the study). At each time point, the plaque index (PI), gingival index (GI) and white spot lesion (WSL) score were recorded. Several app-related parameters were evaluated. Patient-related outcome measures were investigated in the test group.

RESULTS

Test and control groups were similar at baseline except for WSL score. Between T1 and T4, PI and GI decreased significantly in both groups but evolutions were globally similar in both groups. Interestingly, at T3 (12 weeks), the PI was significantly lower in the app group than in the control group (P = 0.014). Data showed a marked decline in the use of the app over time in the test group.

CONCLUSIONS

This trial, conducted over 18 weeks in two academic hospitals, showed no significant effect of the use of the app in promoting oral hygiene.

Orthodontic patients' oral hygiene compliance by utilizing a smartphone application (Brush DJ): a randomized clinical trial

Considering the widespread use of smartphones and their applications (apps), as well as the undeniable role of reminders and apps in behavioral interventions, this study aimed to assess the efficacy of a smartphone app (Brush DJ) for oral hygiene compliance of patients with fixed orthodontic appliances. In this randomized clinical trial, 120 patients between 15 to 25 years who had just started fixed orthodontic treatment were randomly divided into two groups (n = 60). Control patients received conventional oral hygiene instruction, while patients in the intervention group were asked to use the Brush DJ smartphone app, after receiving conventional oral hygiene instruction. The plaque index (PI) and gingival index (GI) were measured at baseline (T0), and at 4 weeks (T1), 8 weeks (T2) and 12 weeks (T3) after the onset of study. A questionnaire was given to all patients to assess the frequency and duration of tooth brushing per day, and the frequency of app usage and reminder noticing in the intervention group. Improvements in PI and GI were noted in the intervention group; while these parameters increased in the control group. Significant differences were noted in PI and GI changes between the two groups (p < 0.001). Brushing frequency and duration were positively correlated with app usage during the follow-up period. Ultimately, we believe that smartphone apps, as motivators and reminders, can greatly help in improving the orthodontic patients’ oral hygiene compliance, especially in adolescents

Efficacy of Behaviour Change Techniques to improve oral hygiene control of individuals undergoing orthodontic therapy. A systematic review

AIM

This study aims to review the available evidence on the efficacy of behaviour change techniques to improve compliance in young orthodontic patients and to compare these with conventional oral hygiene instructions.

METHODS

The review was conducted according to the PRISMA statement. PICO method was used to define eligibility criteria. Two independent reviewers performed the research, examined electronic databases (MEDLINE, Scopus and CENTRAL) and manually checked relevant journals. Only RCTs with more than 10 participants and 3 months follow-up were included. Data extraction and their qualitative analysis were performed for included studies.

RESULTS

Search strategy identified 320 articles. After screening for titles, abstracts and full texts, 10 articles were then selected for qualitative analysis. High methodological heterogeneity was present among studies and therefore no meta-analysis was performed. Low risk of bias was detected for one study only. The most common intervention was "mobile phone communication," which was investigated in five studies. Motivational interviewing, repeated reinforcements and visual-aided approach were also examined.

CONCLUSION

The interest in remote control of patients compliance appears to be fruitful, nonetheless there is no consensus as to a unique treatment protocol. Every other treatment looks beneficial but higher methodological homogeneity should be sought for in future investigations.

Smartphone applications used in orthodontics: A scoping review of scholarly literature

Mobile applications (apps) play an increasingly important role in day to day life. With the number of orthodontic-related apps continuing to increase, and the rapid development of artificial intelligence, the potential to yield tremendous benefits to both clinicians and patients is apparent. However, if orthodontic apps are to become mainstream and obtain greater acceptance, scientific validation and investigation of these apps are to be undertaken. This scoping review aimed to determine the scope and extent of the published literature on mobile apps in orthodontics, as well as identify the types of studies published, and summarize the outcomes studied- thus also giving direction for future research in a rapidly evolving subject area.

Efficacy of mobile health care in patients undergoing fixed orthodontic treatment: A systematic review

OBJECTIVES

We performed a systematic review of studies that assessed the efficacy of mobile health care in patients undergoing fixed orthodontic treatment, in an attempt to obtain contemporary evidence on the clinical impact of mobile health care on the patients' oral health and orthodontic treatment outcomes.

METHODS

A systematic literature search was conducted using the PRISMA guidelines. We performed a comprehensive search using multiple databases (Cochrane Library, MEDLINE, EMBASE, Scopus, Google Scholar and Web of Science) with no restrictions on the language of publication or publication status up until 23 April 2019 to identify eligible studies.

RESULTS

We included 11 unique studies. In this review, 9 of the 11 selected studies showed positive effects of mobile healthcare intervention, which resulted in reduced scores of oral hygiene and periodontal indices and white-spot lesions, as well as decreased duration of treatment, sagittal distance and intensity of self-reported pain.

CONCLUSIONS

Mobile health care can be utilized as an adjuvant intervention to improve treatment outcomes in patients undergoing fixed orthodontic treatment. Oral healthcare experts should consider novel interventions using mobile devices in addition to the conventional mode of intervention.

The effect of different mouth washes and text messages reminder in the oral health of orthodontic patients

Aim: The aim of this study was to investigate the effect of different mouth washes and to study the effect of text message reminder on the oral health status of orthodontic patients treated with fixed appliances. Methods: This study was a clinical trial with pre-test and post-test control group design, conducted on 24 patients undergoing fixed orthodontic treatment aged 15-30 years. The patients randomly divided into two groups; one received a weekly telephone text massage reminder for the instructions of brushing and rinsing while the second group did not receive any messages. Ortho-plaque index and gingival index were used to evaluate the patient’s oral hygiene status. The reading indices after brushing only were regarded as a control, then the patients were instructed to use two mouth washes, one containing sodium fluoride with cetylpyridinium chloride, the second containing chlorhexidine digluconate with cetylpyridinium chloride and Aloe Vera. Each one was used routinely for 4 weeks with the same amount and method. The washout period between the two types mouth washes was 4 weeks with a standardized toothbrush and paste. Results: Ortho-plaque index values decreased over the time between first, second and third visits. However, this index raised up at the fourth visit and again dropdown at the fifth visit. Similar results were detected for gingival index. Also, significant interaction between messages and the assessments was recorded for gingival index with a significant difference between the group of text messages and without text messages group (p<0.05). Conclusions: The results of this study showed that the combination of sodium fluoride with cetylpyridinium chloride was more potent for plaque control, while chlorhexidine digluconate with cetylpyridinium chloride and Aloe Vera combination showed a better gingival improvement. Moreover, the text messages reminder could enhance, but not replace direct oral hygiene instruction in orthodontic patients.

The effect of using a mobile application ("WhiteTeeth") on improving oral hygiene: A randomized controlled trial

Objective

To evaluate the effectiveness of the WhiteTeeth mobile app, a theory‐based mobile health (mHealth) program for promoting oral hygiene in adolescent orthodontic patients.

Methods

In this parallel randomized controlled trial, the data of 132 adolescents were collected during three orthodontic check‐ups: at baseline (T0), at 6‐week follow‐up (T1) and at 12‐week follow‐up (T2). The intervention group was given access to the WhiteTeeth app in addition to usual care (n = 67). The control group received usual care only (n = 65). The oral hygiene outcomes were the presence and the amount of dental plaque (Al‐Anezi and Harradine plaque index), and the total number of sites with gingival bleeding (Bleeding on Marginal Probing Index). Oral health behaviour and its psychosocial factors were measured through a digital questionnaire. We performed linear mixed‐model analyses to determine the intervention effects.

Results

At 6‐week follow‐up, the intervention led to a significant decrease in gingival bleeding (B = −3.74; 95% CI −6.84 to −0.65) and an increase in the use of fluoride mouth rinse (B = 1.93; 95% CI 0.36 to 3.50). At 12‐week follow‐up, dental plaque accumulation (B = −11.32; 95% CI −20.57 to −2.07) and the number of sites covered with plaque (B = −6.77; 95% CI −11.67 to −1.87) had been reduced significantly more in the intervention group than in the control group.

Conclusions

The results show that adolescents with fixed orthodontic appliances can be helped to improve their oral hygiene when usual care is combined with a mobile app that provides oral health education and automatic coaching. Netherlands Trial Registry Identifier: NTR6206: 20 February 2017.

Adherence to Orthodontic Treatment in Youth With Craniofacial Conditions: A Survey of US Orthodontists

OBJECTIVE

(1) To explore orthodontists' perceptions of nonadherence and related factors in their patients with craniofacial conditions; (2) to examine differences in adherence perceptions by provider characteristics; (3) to evaluate current adherence interventions.

DESIGN

Cross-sectional.

SETTING

United States-based orthodontists affiliated with a nonprofit association for providers treating oral cleft and craniofacial conditions received survey invitations via list-serv, e-mail, and social media.

PARTICIPANTS

Thirty-eight orthodontists participated (mean age = 50.5 ± 10.7 years; 76% Caucasian; 55% male; 54% private practice).

MAIN OUTCOME MEASURE

An 80-item survey assessed demographic characteristics; frequencies of various adherence problems and adherence-related prolonged or terminated treatment; importance of adherence to treatment outcomes; factors that may impact adherence; interest in improving adherence; and use of adherence-enhancing interventions.

RESULTS

Adherence problems were common, yet 80.6% of participants rated adherence as "very important" to cleft treatment outcomes. Child behavior and motivation, caregiver reinforcement of behavior, and provider communication with the family were identified as factors that greatly impact adherence. Orthodontists in university-affiliated programs were more likely to rate individual, family, health-care system, and community factors as impacting adherence compared to private practice orthodontists; 80.6% used adherence interventions; these strategies were all rated as "sometimes successful."

CONCLUSIONS

Nonadherence to cleft lip/palate-related orthodontic care is common and potentially detrimental to care. Current interventions are not uniformly successful and could be better tailored. Understanding provider, patient, and family factors that affect adherence can inform individualized treatment planning to improve adherence and ultimately, treatment outcomes.

A method development randomised clinical study investigating efficacy of an experimental oral rinse in providing long-term relief from dentinal hypersensitivity

OBJECTIVES

To evaluate and compare clinical efficacy of a 1.5% dipotassium oxalate monohydrate (KOX)-containing oral rinse ('Test') for the relief of dentinal hypersensitivity (DH) against Negative Control and Placebo oral rinses, adjunctive to twice-daily brushing with a standard fluoride dentifrice, after 8 weeks.

METHODS

This was a randomised, examiner blind, parallel-group, method development study in participants with DH, assessed at baseline and after 4 and 8 weeks by response to an evaporative (air) stimulus (evaluated by Schiff sensitivity score and a 10-point visual rating scale [VRS]) and a tactile stimulus (Yeaple probe). To boost compliance, study features included recruiting only regular oral rinse users, use of an oral rinse during acclimatisation, weekly supervised rinsing and twice-daily text reminders.

RESULTS

After 8 weeks, adjusted mean change from baseline in Schiff sensitivity score was significantly lower in the Test rinse group (n=43) versus the Negative Control group (n=23) (difference: -1.22; 95% CI -1.657, -0.782); tactile threshold score was significantly higher in the Test rinse group compared to the Negative Control rinse (difference: 37.46g; 95% CI: 22.916, 51.995). Similar significant differences in Schiff/tactile scores were also demonstrated after 4 weeks use, after 4 and 8 weeks use as assessed by VRS and as compared to the Placebo rinse (n=23) in all instances. Study products were generally well tolerated.

CONCLUSIONS

The Test rinse showed statistically significant improvements in DH compared to the Negative Control and Placebo rinses after 8 weeks twice daily use. Compliance with the rinsing regimen and study visits was excellent.

CLINICAL SIGNIFICANCE

Additional compliance features incorporated into this dentinal hypersensitivity study - recruitment of regular oral rinse users only, acclimatisation rinse, weekly supervised rinsing at the study site, twice-daily text reminders - appear to have been of benefit to the overall study design as compliance was high, and primary and secondary objectives were met.

Implementing post-orthodontic compliance among adolescents wearing removable retainers through Whatsapp: a pilot study

Purpose: To determine whether the use of social media is useful in improving compliance and follow-up attendance among patients wearing retainers after orthodontic treatment. Patients and methods: Sixty post-orthodontic patients (aged 16-19 years), randomized in two groups: follow-up supported by participation in WhatsApp chat group (SG), and Control Group (CG). All patients were scheduled for quarterly check-ups for monitoring of orthodontic stability by measurement of intercanine width at the beginning of the study (t₀) and every 4 months t₁, t₂, t₃) for 1 year of observation. Patients in the SG additionally participated in a WhatsApp chat group, where they would send, on a weekly basis, snapshots showing his/her occlusion. Every month, the orthodontist acting as the moderator awarded the best five snapshots by publishing a ranking in the chat. Results: Participants in the SG featured smaller changes from the intercanine widths at baseline (at debonding) compared to the CG patients at all times during 1 year of follow-up. Follow-up attendance was regular in both groups in the first 8 months of follow-up. After that, patient compliance decreased in the CG, with eight patients missing check-up appointments. Conclusion: Engaging adolescent patients directly through WhatsApp activity seems to increase regularity in wearing removable retainers, attendance to follow-up schedule, and yield better long-term outcome in terms of orthodontic stability and compliance.

Effect of automated messaging on oral hygiene in adolescent orthodontic patients: A randomized controlled trial

OBJECTIVE

To determine whether automated text messages sent daily to adolescent orthodontic patients improves oral hygiene more than weekly reminders.

MATERIALS AND METHODS

A blinded, prospective, randomized controlled trial was designed to evaluate the effects of automated messages on oral hygiene. Subjects were recruited from patients undergoing orthodontic treatment at the Texas A&M University College of Dentistry, Department of Orthodontics. They were being treated with a variety of fixed full appliances in both arches. Subjects were randomly assigned to either a once-a-week text message group or a daily text message group. There were 52 females and 27 males who were 12 to 17 years of age. Oral hygiene was measured at the beginning of the study and again 8.6 ± 0.9 weeks later.

RESULTS

The daily reminder group (N = 42) had significantly greater improvements in oral hygiene compliance than the weekly reminder group (N = 37). The daily score decreases were 48%, 21% and 19% for the bleeding index (BI), plaque index (PI), and gingival index (GI), respectively. The weekly score decreases were 27%, 14% and 13% for the BI, PI, and GI. There were no sex differences in hygiene changes during the study. The 42% of patients who completed the survey at the end of the study wanted more frequent messages and reported that messages related to decreasing treatment time were the most effective, while those related to oral hygiene were the least effective.

CONCLUSIONS

Daily text messages are more effective at improving oral hygiene than weekly text messages.

Effects of motivational methods on oral hygiene of orthodontic patients: A systematic review and meta-analysis

OBJECTIVE

The aim of our study was to qualitatively and quantitatively synthesize the evidence regarding ways to improve motivation of oral hygiene among orthodontic patients with fixed appliances and identify the effects of motivational methods via comparing the oral hygiene condition before and after the motivations.

METHODS

An electronic search was conducted in PubMed, Ovid, Embase, and the Crochrane Library for relevant random controlled trials (RCT) and clinical controlled trial (CCT) published before May 1, 2017 with manual search in addition. Search and selection of studies, quality assessment, data extraction and synthesis was completed by 2 reviewers independently. Plaque index (PI) and gingival index (GI) at 1, 3, 6-month were pooled with Review Manager 5.3. Bias of included studies was evaluated.

RESULTS

In total, 12 studies fulfilled the inclusion criteria of this systematic review, of which, 5 were included in the meta-analysis. Motivational methods had statistically significant advantage regarding PI in the experimental group over control group at 1, 3, 6-month, while GI was significantly better controlled in the study group at 3, 6-month. The quality of included studies was moderate.

CONCLUSION

It is worthy for orthodontists to put in additional efforts to motivate patients to maintain good oral hygiene throughout the entire treatment process.

A Mobile App (WhiteTeeth) to Promote Good Oral Health Behavior Among Dutch Adolescents with Fixed Orthodontic Appliances: Intervention Mapping Approach

Background

The insertion of fixed orthodontic appliances increases the risk of dental caries, particularly in adolescents. Caries can be prevented through good oral health behavior. To support adolescents with fixed orthodontic appliances and for promoting oral health behavior, we developed a theory- and evidence-based mHealth program, the WhiteTeeth app.

Objective

The objective of our paper was to describe the systematic development and content of the WhiteTeeth app.

Methods

For systematic development of the program, we used the intervention mapping (IM) approach. In this paper, we present the results of applying the first 5 steps of IM to the design of an mHealth program: (1) identifying target behaviors and determinants through problem analysis, including a literature search, a survey study, and semistructured interviews, to explore adolescent oral health behavior during orthodontic therapy; (2) defining program outcomes and objectives; (3) selecting theoretical methods and translating them into practical strategies for the program design; (4) producing the program, including a pilot test with 28 adolescents testing the acceptability and usability of the WhiteTeeth app; and (5) planning implementation and adoption.

Results

On the basis of our literature search, we identified fluoride use and control of dental plaque levels (eg, tooth brushing and proxy brush usage) as target behaviors for preventing caries. Next, we identified important and changeable determinants of oral health behavior that fitted the theoretical concepts of the Health Action Process Approach (HAPA) theory. The HAPA theory, the self-regulation theory, and the results of the semistructured interviews were used to define the program objectives, that is, the performance and change objectives. After defining the objectives, we identified multiple behavior change techniques that could be used to achieve these objectives, such as providing oral health information and feedback, prompting self-monitoring, coaching of set actions and coping plans, and sending reminders. We translated these methods into practical strategies, such as videos and a brushing timer. Next, we combined these strategies into a single program resulting in the WhiteTeeth app (which is available on both iTunes and Google Play stores as “Witgebit”). Adolescents with fixed orthodontic appliances and dental professionals were included in the development process to increase the success of implementation. The pilot test revealed that the app users appreciated and liked the app. The WhiteTeeth app can be integrated into current orthodontic care.

Conclusions

IM allowed us to identify multiple techniques that have been shown to be the most effective in initiating behavior change, but have not yet been incorporated into existing orthodontic apps. The WhiteTeeth app contains all these techniques, which makes it a unique and promising home-based app for promoting oral health in adolescents with fixed orthodontic appliances.

The influence of text messages on the cooperation of Class II patients regarding the use of intermaxillary elastics

OBJECTIVES

To evaluate the influence of text messages on cooperation of Class II patients with the use of intermaxillary elastics.

MATERIALS AND METHODS

The sample consisted of 42 orthodontic patients (20 males and 22 females) aged between 14 and 34 years. They were randomly divided into one of the following two groups: a control group with 21 patients who did not receive messages and an experimental group with 21 patients who received motivational and reminder text messages. Messages were sent twice a week for a period of 3 months. The patients were instructed to wear the elastics all day, removing them only during meals and replacing them daily. All patients were instructed regarding the importance of cooperation. Measurements were performed with a digital caliper on plaster models at the beginning of elastics wear (T1) and 3 months later (T2). For intragroup and intergroup comparisons between T1 and T2, paired and unpaired t-tests, respectively, were used with a significance level of 5%.

RESULTS

Statistically significant differences were observed in the intra- and intergroup comparisons between T1 and T2. Both groups showed a decrease in the sagittal distance between upper and lower arches from T1 to T2, demonstrating the effective use of elastics. However, the experimental group showed a Class II correction that was 3.7 times greater than the control group ( P = .001).

CONCLUSIONS

Text messages had a positive influence on the cooperation of patients regarding the use of intermaxillary elastics in the orthodontic treatment of Class II malocclusion.

Using text message reminders in health care services: A narrative literature review

INTRODUCTION

Despite the extensive use of mHealth behavior change interventions, questions remain about the use of technology-based reminders in delivering health care services. Text messaging, or short message service (SMS), is one reminder method that has been extensively researched. Most SMS-reminder research is distributed across a range of health care outcomes. The aim of this article is to systematically review the aggregate impact of these reminders on overall health care outcomes.

METHODS

A systematic literature review was conducted and yielded 2316 articles. Studies were included if they used SMS reminders to support patient health care outcomes. Study methodology was aligned with the PRISMA guidelines for systematic reviews.

RESULTS

Following screening, 162 articles met inclusion criteria. Of these studies, 93 investigated medical compliance reminders and 56 investigated appointment reminders. The review found that nearly all the SMS-reminder studies helped improve patient medical compliance and appointment reminders. Additionally, researchers reported numerous benefits from using SMS reminders, including ease of use, relative inexpensiveness, and rapid and automated message delivery. Minimal risks were reported and most participants found the reminders to be acceptable.

DISCUSSION

Text messages appear to be an effective reminder mechanism to promote improved patient appointment and medical compliance. Reminders should continue to be evaluated and improved to determine the most effective timing and frequency of messages for improving outcomes.

Influence of reminder therapy for controlling bacterial plaque in patients undergoing orthodontic treatment: A systematic review and meta-analysis

OBJECTIVE

To assess the scientific evidence regarding the influence of reminder therapy on plaque index, gingival index, and white spots in patients subjected to orthodontic treatment.

MATERIALS AND METHODS

Randomized clinical trials were searched in the electronic databases LILACS, PubMed, SciELO, Scopus, Web of Science, Embase, LIVIVO, and Cochrane Library. The databases OpenThesis and OpenGrey were used to capture the "gray literature," preventing selection and publication biases. The risk of bias was assessed by the Joanna Briggs Institute Critical Appraisal Checklist for Randomized Controlled Trials tool. The software Review Manager was used for the meta-analysis. The heterogeneity among studies was assessed through the I ² statistic. A summary of the overall strength of evidence available was assessed using the Grades of Recommendations Assessment, Development, and Evaluation tool.

RESULTS

A total of 332 records were found, from which only 7 articles met the inclusion criteria and were subjected to analysis. Reminder therapy showed improved scores for the plaque index (standardized mean difference = -1.22; 95% confidence interval = -2.03 to -0.42; P = .003) and the gingival index (standardized mean difference = 1.49; 95% confidence interval = -2.61 to 0.37; P = .009). Moreover, there was lower occurrence of white spots (relative risk = 0.53; 95% confidence interval = 0.38 to 0.74; P < .001) when reminder therapy was implemented.

CONCLUSIONS

According to the existing high-quality evidence, reminder therapy is a valuable strategy and may contribute to the reduction of plaque and gingival indices as well as to the lower occurrence of white spots in patients subjected to orthodontic treatment.

Role of Text Message Reminder on Oral Hygiene Maintenance of Orthodontic Patients

INTRODUCTION

Fixed orthodontic treatment is frequently associated with increased plaque accumulation leading to gingivitis and white spot lesions (WSLs).

AIM

This study evaluated the role of text message reminder on oral hygiene of orthodontic patients.

MATERIALS AND METHODS

A total of 60 patients under fixed orthodontic treatment were randomly divided into two equal groups as control group and study (text message) group. Text message group received reminders about oral hygiene, while the control group did not receive any messages. Oral hygiene of both the groups was evaluated at baseline, 2, and 3 months using plaque indices (PIs) along with WSL status. Data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) statistical software, version 19, with chi-square test and t-test.

RESULTS

At the baseline, plaque score was higher in the study group over control group (p > 0.038), whereas it was decreased after 3 months in the test group (p > 0.001). For WSL, there was no significant difference at baseline, but it was significantly lower in study group (p > 0.003).

CONCLUSION

Oral hygiene status improved with text message reminder.

Oral hygiene compliance in orthodontic patients: a randomized controlled study on the effects of a post-treatment communication

Background

Several studies have recently demonstrated that a post-treatment communication to explain the importance of an oral hygiene can improve the orthodontic patients’ compliance over a period of 66 days. The main goal of this study is to evaluate the effects of a structured follow-up communication after orthodontic appliance application on oral hygiene compliance after 30–40 days.

Methods

Eighty-four orthodontic participants enrolled from patients who were beginning fixed orthodontic treatment at the Orthodontic Department, Gaslini Hospital, Genova, between July and October 2014 were randomly assigned to one of three trial arms. Before the bonding, all patients underwent a session of oral hygiene aimed at obtaining an plaque index of “zero.” At the following orthodontic appointment, the plaque index was calculated for each patient in order to assess oral hygiene compliance. The first group served as control and did not receive any post-procedure communication, the second group received a structured text message giving reassurance, and the third group received a structured telephone call. Participants were blinded to group assignment and were not made aware that the text message or the telephone call was part of the study. (The research protocol was approved by the Italian Comitato Etico Regionale della Liguria-sezione 3^ c/o IRCCS-Istituto G. Gaslini 845/2014, and it is not registered in the trial’s register.)

Results

Thirty patients were randomly assigned to the control group, 28 participants to the text message group, and 26 to the telephone group.

Participants who received a post-treatment communication reported higher level of oral hygiene compliance than participants in the control group. The plaque index was 0.3 (interquartile range (Iqr), 0.60) and 0.75 (Iqr, 1.30), respectively, with a significant difference (P = 0.0205).

Conclusions

A follow-up procedure after orthodontic treatment may be an effective tool to increase oral hygiene compliance also over a short period.

Quantitative Light-induced Fluorescence-Digital as an oral hygiene evaluation tool to assess plaque accumulation and enamel demineralization in orthodontics

OBJECTIVE

  To assess the use of Quantitative Light-induced Fluorescence-Digital as an oral hygiene evaluation tool during orthodontic treatment.

MATERIALS AND METHODS

  In this prospective, randomized clinical trial, 33 patients undergoing fixed orthodontic appliance treatment were randomly allocated to receive oral hygiene reinforcement at four consecutive appointments using either white light (WL) or Quantitative Light-induced Fluorescence-Digital (QLF) images, taken with a device, as visual aids. Oral hygiene was recorded assessing the QLF images for demineralization, by fluorescence loss (ΔF), and plaque coverage (ΔR30). A debriefing questionnaire ascertained patient perspectives.

RESULTS

  There were no significant differences in demineralization (P  =  .56) or plaque accumulation (P  =  .82) between the WL and QLF groups from T0 to T4. There was no significant reduction in demineralization, ΔF, in the WL, or the QLF group from T0-T4 (P > .05); however, there was a significant reduction in ΔR30 plaque scores (P < .05). All the participants found being shown the images helpful, with 100% of the QLF group reflecting that it would be useful to have oral hygiene reinforcement for the full duration of treatment compared with 81% of the WL group (OR 2.3; P < .05).

CONCLUSIONS

  Quantitative Light-induced Fluorescence-Digital can be used to detect and monitor demineralization and plaque during orthodontics. Oral hygiene reinforcement at consecutive appointments using WL or QLF images as visual aids is effective in reducing plaque coverage. In terms of clinical benefits, QLF and WL images are of similar effectiveness; however, patients preferred the QLF images.

Effect of Reinforcement of Oral Health Education Message through Short Messaging Service in Mobile Phones: A Quasi-Experimental Trial

Objective. This paper aims to assess the effectiveness of reinforcement of oral health education message through short messaging service (SMS) in mobile phones. Material and Methods. 400 subjects from two colleges (200 from each college) belonging to 18–20 years age group possessing mobile phones were randomly selected and baseline examination of oral hygiene and gingival status was carried out using Oral Hygiene Index (OHI) and Gingival Index (GI). Oral health education was provided to all the subjects. Oral health education message was reinforced through short messaging service (SMS) in mobile phones for the subjects belonging to the intervention group. There was no such reinforcement for the control group. Follow-up examinations were done at the end of 1st, 2nd, 3rd, and 6th month. After the 3rd month, subjects of the intervention group did not receive oral health education message through short messaging service (SMS) and were followed up after next three months. Compiled data was analyzed using SPSS version 16 statistical software. Result. Mean OHI and GI scores in intervention group were significantly (p < 0.01) less than those of control group after the 2nd, 3rd, and 6th month. Conclusion. Reinforcement of oral health education message through short messaging service (SMS) is effective media to improve oral health.
