Patients' Perceptions To Reduced Orthodontic Treatment Time In Saudi Arabia.

PURPOSE: To evaluate patients' perceptions regarding orthodontic treatment duration, cost, and willingness to undergo different procedures and techniques available to accelerate orthodontic tooth movement in Saudi Arabia. PATIENTS AND METHODS: A cross-sectional survey was conducted in Saudi Arabia from January to March 2019. Patients from multiple centers were electronically surveyed regarding their perception of orthodontic treatment duration, acceptance of appliances and techniques available to shorten the duration of orthodontic treatment, and how much increase in fees they were willing to pay for those appliances and techniques. Descriptive and group comparison statistics were conducted, and the significance level was set at p<0.05.
RESULTS: The response rate was 200/400 (50%): 50.5% were (>18-25 years old), 67.5% female, 80% Saudi, 67.5% self-pay and 52% with annual income <10,000 SR. A total of 83% of the participants agree that orthodontic treatment takes too long, and 55.5% wish it takes less than 6 months. The preferences for additional procedures were ranked in the following order: customized wires ranked 1 by 52.5%, followed by FDA (Food & Drug Administration) approved teeth vibrators by 40.5%, FDA approved drug injections by 33.5%, piezocision by 32.5%, and corticotomies by 46% of the participants. No significant differences in ranking between the groups according to age and annual income (p>0.05). 47.5% of the participants were able to pay for additional procedures. An increase in treatment fees was reported for up to (30-40%) for FDA approved teeth vibrators by 59% of the participants, followed by FDA approved drug injections by 33% of the participants. A significant difference in responses between the groups was reported according to gender and annual income (p<0.05).
CONCLUSION: Most of the patients strongly agreed that orthodontics treatment takes too long. The highest percentages of patients perceived customized wires as the most acceptable technique to undergo to shorten orthodontic treatment duration, followed by teeth vibrators.

Introduction

The number of people requesting for orthodontic treatment is increasing because of multiple reasons. However, the prolonged duration of orthodontic treatment time, as well as the increased treatment charges, could be a concern for patients seeking orthodontic treatment. In addition, root resorption and white spot lesions as sequelae of prolonged orthodontic treatment are considered major risks of concern to both patients and professions.1–3

Multiple techniques and procedures have been reported to accelerate orthodontic tooth movement, and thus, shorten treatment duration, thereby, reducing the potential treatment risks.2–9 Varied biological, mechanical, and physical effects of such procedures that also varied in their level of invasiveness.2,4,7,9

Orthodontic treatment coupled with the use of teeth vibrator devices for physical stimulation by vibratory forces is one of the recommended techniques.4,6,7,9 Woodhouse et al, compared patients’ pain expression between conventional fixed orthodontic appliances and the use of supplemental vibrational devices and found no significant difference in pain between both methods.8 Mechanical stimulation by customized wires designed and manufactured according to the desired movement and the formulated treatment plan was also reported to reduce the treatment time significantly.6,10,11 Despite the non-invasiveness of these mechanical techniques, the increase in treatment costs has been considered an issue.4,6,7,9,10

Procedures reported to have biological effects included: one-time surgical procedures and drug injections. The one-time surgical procedures reported include corticotomies and piezocisions.4,9,12–14 These procedures are based on the principle of induced inflammatory effect induced on bone leading to accelerated osteoclastic effect and thus, accelerate tooth movement.4,7,9,12–16 Corticotomies were considered invasive, reported to be accompanied with some reported postoperative pain.12–14,16 In contrast, piezocision appeared to be an effective method to reduce the orthodontic treatment time without any unwanted sequelae.5 It was also reported to have a high level of acceptance and satisfaction among patients.14

The drug injection method includes the injection of exogenous inflammatory mediators and hormones into the periodontal tissues to induce bone resorption.7 Multiple mediators have been assessed including vitamin D and parathyroid hormones with positive reported effects on orthodontic tooth movement.17 However, most studies assessing these mediators have been animal studies.4,9

Among the different techniques, the less-invasive ones were reported to be more accepted by adult and adolescent patients as well as orthodontists as reported by Uribe et al.2

Patients’ perceptions toward orthodontic treatment modalities have been reported to be influenced by different factors such as age, gender, nationality, treatment cost, level of income and level of education.1–3,18,19 According to a report by Uribe et al, patients were willing to pay up to 20% increase in the treatment cost, for any procedure that could reduce their orthodontic treatment duration.2 Bindayel, in 2018, assessed the awareness and preferences of patients in Saudi Arabia to different orthodontic treatment modalities and payment options. He found that treatment costs and payment plan affected patients’ preferences for the different orthodontic treatment modalities.19 In addition, Sayers and Newton also found that ethnic background had a significant effect on patients’ expectation of orthodontic treatment.20

To the best of our knowledge, patients’ perceptions of the need for reduced orthodontic treatment time as well as their acceptance to the different procedures claimed to accelerate orthodontic tooth movement have not been assessed in Saudi Arabia.

The aim of this study was to evaluate patients’ perceptions regarding orthodontic treatment duration, cost, and willingness to undergo different procedures and techniques available to accelerate the rate of orthodontic tooth movement in Saudi Arabia.

Materials And Methods

This was a cross-sectional survey conducted in Saudi Arabia from January to March 2019. The study was approved by the Ethical committee at King Abdulaziz University, Faculty of Dentistry, Jeddah, Saudi Arabia.

The questionnaire was adopted from the study conducted by Uribe et al, 2014.2 It consisted of multiple-choice questions, 5-Likert scale questions and rank-order questions.

The questions were designed to assess the following variables:

Demographic data including age, gender, nationality, education, annual income and methods of payment for orthodontic treatment

Preferences for orthodontic treatment duration.

Willingness to undergo additional procedures and techniques available to shorten the duration of orthodontic treatment. The assessed procedures included: customized wires, corticotomies (described as bone cuts), FDA approved teeth vibrators, piezocision (described as gum cuts), and FDA approved drug injections.

Ability to pay to reduce orthodontic treatment time, willingness to pay for the different procedures and techniques available to shorten the duration of orthodontic treatment, and how much increase in fees they were willing to pay for the reduction in treatment time.

Patients undergoing orthodontic treatment from multiple private and governmental dental centers in Jeddah, Saudi Arabia were included in the study. The electronic survey was given to 400 orthodontic patients by self-administering or sending messages with links to the survey and their responses were recorded. Accordingly, a clear introduction and definitions of the various procedures and techniques proposed to reduce orthodontic treatment time were described in the questionnaire. All participants provided written informed consent, and the survey was conducted in accordance with the Declaration of Helsinki.

Statistical Analysis

Data were collected using Google Forms. Descriptive statistics were calculated for frequencies and percentages. Group comparisons were conducted using the Mann–Whitney U-test for gender and Kruskal Wallis test for age and annual income comparisons. Data were analyzed using Excel (Microsoft Excel 2007, Microsoft Corporation, Redmond, WA, USA) and SPSS (IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp, USA). The significance level was set at (p<0.05).

Results

The questionnaire was sent to 400 patients, out of which, only 200 (50%) patients responded.

Sample Distribution

The sample characteristics including age, gender, nationality, education, annual income and methods of payment for orthodontic treatment are represented in Table 1. Out of the total number of participants, 50.5% were from the age group of >18–25 years old, 67.5% were female, 80% were Saudi, 67.5% were self-pay and 52% had an annual income <10,000 SR.

Preferences For Orthodontic Treatment Duration

The participants responses to perceptions towards the duration of orthodontic treatment are presented in Table 2. Eighty-three percent of the participants believed that orthodontic treatment takes too long (56% strongly agreed and 27% somewhat agreed). A significant difference in their perception was reported according to gender (female more than male) and according to annual income (mainly from participants with income <10,0000) (p<0.05). Forty-six percent expected orthodontic treatment to take less than 12 months, while 31% expected it to take 12–18 months. However, 55.5% wished it took less than 6 months and 30% wished it took 6–12 months for orthodontic treatment to complete. A significant difference in their wishes was reported according to gender only (female more than male) (p<0.05).

Discussion

The aim of this study was to evaluate patients’ perceptions regarding orthodontic treatment duration, cost, and willingness to undergo different procedures and techniques available to accelerate the rate of orthodontic tooth movement in Saudi Arabia. The age group interested in the subject of the survey was mainly from the middle-aged. Similarly, Kim, in 2005, assessed patients’ perceptions towards orthodontic treatment among adults categorized according to age, sex, and area of living. Similar to our study, he found that the middle-aged group had a relatively higher percentage of interest in orthodontic treatment. He also found that neither gender nor area of living was significantly associated with the positive interest in orthodontic treatment.3

More than half of the participants agreed that orthodontic treatment was time-consuming, and they wished it took less than 6 months, which is similar to the findings reported by Uribe et al.2 However, the expectation of the participants in the current study about how long orthodontic treatment should take was in accordance with their wishes, which is in contrast to the finding of Uribe et al.2

The results showed that customized wires followed by FDA approved teeth vibrators and FDA approved drug injections were the most preferred procedures to undergo among different procedures and techniques. In contrast, participants were mostly unwilling to undergo corticotomies and piezocisions. The same ranking was reported both when the advice was for 20–30% reduction in treatment time for all procedures and when each procedure was estimated to reduce the treatment time, even though corticotomies were suggested to result in 50% reduction of treatment time. The same findings were reported by Uribe et al.2 It was not surprising to find that patients preferred the less-invasive nonsurgical procedures as also reported by many other studies.12–14 Current findings indicated no significant effect of age, gender and annual income in the reported preferences for the procedures assessed.

Results also indicated that 47.5% of the participants were able to pay for additional procedures to reduce orthodontic treatment time, while 27% were neutral in their response. Their willingness to pay according to procedure preferences were as follows: 60.5% of the participants were willing to pay for customized wires, 53.5% for FDA approved teeth vibrators, and 45% of the participants were willing to pay for FDA approved drug injections. On the other hand, 49.5% of the participants were unwilling to pay for corticotomies, and 49.5% were unwilling to pay for piezocision. However, when they were asked for the percentage increase in treatment fees, their responses to their preferred non-invasive procedures were as follows: for customized wires, 60% of the participants were ready to pay but only for a 10–20% increase in treatment fees. On the other hand, for FDA approved teeth vibrators, 59.5% of the participants were ready to pay 10–20% increase in fees and 59% were ready to pay 30–40% increase in fees. For FDA approved drug injections, 58.5% of the participants were ready to pay 10–20% increase in fees and 33% were ready to pay 30–40% increase in fees. However, responses of the participants for willingness to pay were significantly affected by gender and annual income variables in the current study. This supports the finding of Wall and Bindayel who reported that the treatment modality choice is affected by financial measures.18,19

The current findings indicated that participants were willing to pay an increase of only up to 10–20% in the treatment fees, despite the reduction in treatment time, except if there was 50% reduction in treatment time, where 52.5% of the participants were willing to pay 10–20% increase in treatment fees and 29% were willing to pay even up to 50% increase in treatment fees. In contrast to the findings of Uribe et al, the percentage reduction in time was not matched with the percentage increase in fees.2 Current findings also indicated no significant effect of age, gender and annual income in most of the reported responses for the increase in treatment fess for a specific reduction in treatment time.

Limitations

As the study design was a cross-sectional survey, the major limitations were causal interference and information bias. Also, the external validity could be limited to Jeddah as the patients evaluated were only from the multiple centers of Jeddah.

Conclusion

The age group interested in the subject of the survey was mainly from the middle-aged.

More than half of the participants agreed that orthodontic treatment takes too long, and they wished it takes less than 6 months.

The non-invasive, non-surgical procedures: customized wires followed by FDA approved teeth vibrators and FDA approved drug injections were the most preferred procedures to undergo as well as willing to pay among different procedures and techniques.

Almost half of the participants were able to pay for additional procedures to reduce orthodontic treatment time.

Participants were only willing to pay up to 10–20% increase in fees for most procedures. However, for FDA approved teeth vibrators and FDA approved drug injections, participants were ready to pay up to 30–40% increase in treatment fees.

The participants were willing to increase treatment fees only up to 10–20% despite the reduction in treatment time, except for the 50% reduction in treatment time where participants were willing to pay for up to 50% increase in treatment fees.

No significant effect of age, gender and annual income on the reported preferences to undergo the additional procedures, while gender and annual income did have an effect on the willingness to pay extra fees for those procedures.
