Orthodontic treatment need among young Saudis attending public versus private dental practices in Riyadh

An epidemiological study on early orthodontic treatment need among eastern Saudi Arabian children in the mixed dentition stage

Estimation of early orthodontic treatment need among children is essential for planning orthodontic interventions in the mixed dentition stages thereby reducing the burden in a publicly funded healthcare system. The present study aimed to assess the early orthodontic treatment need among children with mixed dentition in the Eastern Saudi Arabia. A descriptive cross-sectional study was conducted among Saudi children visiting the outpatient clinics in a University dental setting, and data were collected based on Index for preventive and interceptive orthodontic need (IPION). Descriptive statistics, chi-square test and Fisher's exact test were used for data analysis with statistical significance set at p < 0.05. The category of 'no treatment need' accounted for 11.3% while 'moderate treatment need' and 'definite treatment need' categories accounted for 29.3% and 59.4% respectively. There was no statistical difference between males and females in the distribution of the three categories of treatment need (p = 0.513). This study demonstrated a very high need for early orthodontic treatment among Saudi children in the mixed dentition stage. Emphasis should be placed on increased awareness and benefits of seeking early orthodontic treatment involving preventive and interceptive procedures in the mixed dentition.

Impact of Dental Aesthetic Index characteristics on the severity levels of malocclusion in a non-White population

INTRODUCTION

This study evaluated the impact of the esthetic and occlusal characteristics of the Dental Aesthetic Index (DAI) on the need for orthodontic treatment in a non-White population.

METHODS

A cross-sectional study was conducted with 1296 non-White adolescents aged 12 years. DAI was the outcome variable (DAI 1 and 2 and DAI 3 and 4). The independent variables were categorized on the basis of the occlusal esthetic characteristics evaluated by DAI (tooth absence, crowding, spacing, midline diastema, maxillary misalignment, mandibular misalignment, maxillary anterior overjet, mandibular overjet, anterior open bite, and anteroposterior molar relationship). Simple logistic regression models were adjusted for the outcome, and the raw odds ratios were estimated. Variables with a P value of <0.20 for individual analyses were tested in a multiple logistic regression model, with P ≤0.05 remaining.

RESULTS

A total of 1296 adolescents (764 girls and 532 boys) were evaluated; 1067 (82.3%) had DAI 1 or 2 (minor to a moderate need for orthodontic treatment), and 229 (17.7%) had DAI 3 or 4 (defined need for orthodontic treatment). The results showed that adolescents with diastema, maxillary irregularity, mandibular irregularity, mandibular overjet, anterior open bite, and the altered molar relationship had 5.34, 2.36, 2.63, 3.56, 8.73, and 5.16 times more likelihood to have DAI 3 or 4 (P ≤0.05), respectively.

CONCLUSIONS

Diastema, maxillary and mandibular misalignment, mandibular overjet, anterior open bite, and anteroposterior molar relationship were the characteristics that influenced the determination of the need for orthodontic treatment in a non-White population using the DAI index.

Adult Perceptions of Different Orthodontic Appliances

Introduction: Pursuing an esthetically-pleasing orthodontic outcome, orthodontic patients must consider and choose from the different available options of orthodontic appliance. Practitioners need to be better informed of their customers' preferences to make better practice management decisions and satisfy their patients' needs.

PURPOSE

To explore adult laypeople's perceptions of the attractiveness, acceptability, preference and economic value of different orthodontic appliances when they consider these appliances for themselves and for their children.

PATIENTS AND METHODS

This cross-sectional survey included 199 adults (110 females). The average age of participants was 27.7 years. Participants answered a questionnaire evaluating and comparing multiple smiling images of an adult wearing different orthodontic appliances. Participants rated each appliance for: (1) attractiveness on a Likert scale; (2) acceptability of having the appliance placed for themselves and their children (with a yes/no response); (3) preference (by ranking all appliances in order); and (4) economic value (by providing the additional amount they are willing to pay for each appliance for themselves and their children).

RESULTS

We found a statistically significant difference in the attractiveness scores between the different orthodontic appliances (p< 0.0001). The most attractive appliances were clear aligners and lingual brackets. The least attractive appliances were colored o-tied-brackets followed by shaped-brackets. Clear aligners were the most acceptable appliances among our participants to have placed on themselves (86.9%) and their children (84.9%). Shaped brackets were the least acceptable appliances among our participants to have placed on themselves (24.1%) and their children (36.2%). The most preferred appliances were lingual brackets (39.2%), followed by clear aligners (34.17%). The least preferred appliances were colored o-tied-brackets (4%). Participants varied with regards to how much more they were willing to pay for each of the different orthodontic appliances. The majority were willing to pay more for clear aligners and lingual brackets to have them placed on themselves but not to have them placed on their children.

CONCLUSION

Adults preferred more innovative esthetic appliances over traditional ones and were willing to pay more to have them placed on themselves but not on their children.

Self-Perception Of Malocclusion And Barriers To Orthodontic Care: A Cross-Sectional Study In Al-Madinah, Saudi Arabia

PURPOSE

This study was conducted to assess adult levels of knowledge, awareness of malocclusion and barriers to the uptake of orthodontic care alongside the associated factors (sex and gender).

METHODS

A convenience sample aged 18 years and above, residing in Al-Madinah Al-Munawwarah, Saudi Arabia, was recruited. A self-administrated validated questionnaire was used to collect the data, and data descriptive and inferential statistical analysis were performed.

RESULTS

Of the 700 distributed questionnaires, 554 usable were returned (response rate = 79%). The mean±SD age of participants was 26.40 (±7.87) years and 55.2% were females. Over 60% of the participants reported high oral health knowledge with respect to the alignment of teeth being important for esthetics and neglected malocclusion had consequences, eg, caries. Likewise, high percentages were having knowledge that thumb sucking (80%) contributed to malocclusion although early extraction of primary teeth and genetics was reported by just 52% and 40%, respectively. Awareness of the importance of teeth alignment was reported by 81.6%; however, 37.7% were only advised for orthodontic treatment. Notably, most of the aforementioned knowledge and awareness was statistically significantly higher among females compared to counterpart males (p < 0.05). As for barriers, high orthodontic treatment fees were the barrier for 80% of the total participants irrespective of age and gender. Females were statistically significantly more likely to report barriers for orthodontic care, eg, accessibility and length of treatment (p < 0.05).

CONCLUSION

The majority of the participants scored high levels of knowledge and awareness of oral health-specific conditions in relation to malocclusion. Although females were significantly knowledgeable and aware of malocclusion compared to males, social and orthodontic treatment factors were perceived as barriers to uptake of orthodontic care.

Orthodontic treatment needs in Saudi young adults and manpower requirements

Objectives:

To evaluate orthodontic treatment needs using the index of orthodontic treatment need (IOTN) components and to estimate the required manpower in the city of Jeddah, Saudi Arabia.

Methods:

A cross-sectional study involving 670 participants (390 females and 280 males) collected between November 2016 and April 2017, whose ages ranged from 12-19 years from secondary and high school students. Treatment needs were estimated using the IOTN components, dental health component (DHC), and aesthetic component (AC).

Results:

The results according to the severity of malocclusion using IOTN-DHC found that 24.3% of the cases required severe/extreme need and 54.3% were in the no/slight need category. The most frequent types of malocclusion were crowding (48.8%) followed by increased overjet (21.8%), and spacing (16.1%). Using Pearson’s Chi-squared test, there was a statistically significant association (p<0.001) between IOTN-DHC and IOTN-AC; 51.2% of the sample was in agreement at the mild need category, indicating a strong correlation, with a coefficient of 0.687.

Conclusion:

According to the IOTN’s components, the present study showed that almost one-quarter of the sample had a severe/extreme need for orthodontic treatment. The most frequent type of malocclusion traits according to the severity was crowding followed by increased overjet and then spacing. The Ministry of Health must employ 90-110 orthodontists in Jeddah to meet the demands of the definite needs for orthodontics in adolescents.

Orthodontic Treatment Need in Higher Primary Schoolchildren of Central Bengaluru, India

Aims and Objective:

The aim of this study was to evaluate the orthodontic treatment need in 11–14-year-old schoolchildren of Central Bengaluru, India, using the index of orthodontic treatment need (IOTN) and to analyze the treatment needs between males and females and correlation between the esthetic to aesthetic (AC) and dental health component (DHC) of IOTN.

Materials and Methods:

The sample comprised 500 schoolchildren (187 females and 313 males) who had not undergone orthodontic treatment. No radiographs, study casts, were used; IOTN was calculated from clinical examination and photographs. The data were analyzed using SPSS 20 IBM version.

Results:

The results for DHC were as follows: 12% students in no need, 52.5% students in little need, 20.5% students in moderate or borderline, 11.5% students in severe need, and 3.5% students were in the category of very severe need for treatment. On evaluating AC components, 91.6% were in the category of no or little need, 2% students in moderate need, and 6.4% in great need category. Mild positive correlation (r = 0.153) between DHC and AC of IOTN was observed. The difference between the IOTN values of boys and girls was not statistically significant.

Conclusions:

More than 50% of the population in our study showed little/no need category which undergoes undiagnosed and may not seek dental treatment at right time to prevent the future complications. This study provides baseline data on the need and demand for orthodontic treatment among the sample which is important for planning public orthodontic and dental services.
