PurposeTo 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 methodsA 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.ResultsThe 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).ConclusionMost 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.

Objectives:The objective was to compare dentofacial characteristics of Class I malocclusion in Saudi and Japanese adult females.Materials and Methods:Lateral cephalograms of 50 Saudi adult female and 50 Japanese adult female (18–35-year-old) were obtained. All patients were skeletal Class I, angle Class I malocclusion, arch length discrepancy (−10–10 mm), overjet (1–5 mm), overbite (1–5 mm), absence of congenital anomalies, or significant facial asymmetries or congenitally missing tooth other than the 3rd molar and absence of temporomandibular joint problems. Patient cephalograms were traced and digitized. 16 angular measurements and 13 linear measurements of facial form were used.Results:A comparison of the vertical dimension showed that the Saudi females had a significantly larger gonial angle, a significantly larger facial angle and longer lower face height compared to the Japanese females. Dentally, Saudi females had more protruded incisors with increased distances of the posterior teeth to the palatal plane. For the soft tissue dimension, the Saudi subjects had a significantly more prominent nose, retruded lip and a more protruded chin compared with Japanese.Conclusions:There were significant differences in dentofacial morphology between Saudi and Japanese adult females. Both Asian countries have distinct cephalometric features, which should be considered as a reference in treating patients of varying ethnic backgrounds to optimize the final results.

To evaluate the preference of young adult patients and their willingness to pay for the different approaches accessible to accelerate orthodontic tooth movement. A cross-sectional survey was conducted in Jeddah, Saudi Arabia from September to December 2019. Young adult orthodontic patients from 18 to 45 years old were interviewed via online survey regarding their perception to the extent of treatment, acceptability of non-invasive (customized appliances and medications) and invasive (surgery) approaches accessible to accelerate orthodontic treatment and increase in fees they were willing to pay. Statistical analyses were performed, and gender difference was calculated at P < .05. There are 100 respondents: 70% aged between 18 to 25, 50% male, and 56% with annual income <10 000 SR. About 72% of the respondents decided that treatment takes longer period and 51% wished it would last for less than 6 months. Customized appliances were reported to be the most convenient to use (58%) and to pay (44%), followed by medications (48%). On the other hand, surgery was reported to be the most inconvenient to use (58%) and to pay for (55%). About 70% of the respondents were unwilling to pay more than 10% to 20% for all procedures assessed; considerable variation was not observed in responses between gender at 95% confidence level. Majority of the respondents believed that orthodontic treatment is taking lengthy duration. Less invasive, nonsurgical techniques and procedures were more preferred. Likewise, financial factors play vital role in the selection of their preferred approach. Most of them agrees to provide up to 20% increment of the fee for additional procedures.

Objectives To analyze adaptational changes in clear aligner fit after intraoral usage at different sets of time. Materials and Methods Eight Invisalign appliances (Align Technology, San Jose, California, USA) were collected after intraoral usage. Acrylic imprints of the lower incisor region were constructed for each appliance at T0 (unused appliance). Two appliances were then used intra-orally for each of the following defined periods of time: 3 days, 7 days, 10 days, or 15 days. Used aligners were adapted on its T0 imprint and both were sectioned buccolingually from the distal surfaces of each incisor at the attachment area. Eight surfaces were collected for each set of time (n = 32 surfaces). Microphotographs of obtained sections and micrometric measurements of aligner fit were recorded at five different levels using scanning electron microscopy (SEM). Mean values of the fit changes (gap width) and group comparisons were statistically analyzed using analysis of variance and Tukey's post hoc tests. Significance level was set at P &lt; .05. Results Highly significant differences in aligner fit were found at the different time points assessed (P &lt; .001) with the least mean gap width at 15 days (176 ± 98 μm) and the highest at 7 days (269 ± 145 μm). Significant differences in aligner fit at different attachment levels were also found (P &lt; .01) with the least mean gap width at the middle of the labial surface of the attachment (187 ± 118 μm). Conclusions The 15-day period of intraoral aligner wear might still be recommended as it showed the best adaptation and least gap width between the aligner and the attachment.

Statement of problem: Prosthodontics has received significant attention both in research and practice. However, limited research examines its prevalence and how effective it is. Purpose: The purpose of this clinical study is to examine the prevalence of prosthodontics and its associated complications Material and methods: A sample of 1005 individuals derived from the general Saudi Arabia was used in this study. Data was collected using a questionnaire. The data collected was analyzed using SPSS. Results: There is a generally low prevalence of prosthodontics in Saudi Arabia. The common type of prosthodontics used is the fixed prosthodontics. Majority of those who have done prosthodontics didnt suffer any associated complications. However, for those who depicted complications, the common one was caries. Other complications include root fracture and porcelain veneer fracture. Conclusion: Prosthodontics is not widely used. On the other hand, it is not 100% effective in treating oral health problems. Clinical implications: There is need to develop better ways of dealing with poor oral health and patients need to be examined well to determine the underlying risk factors before prosthodontics is carried out.
