OBJECTIVES: To develop and test the validity and reliability of an Arabic version of the psychosocial impact of dental aesthetics questionnaire (PIDAQ). MATERIALS AND METHODS: The original English version was translated into Arabic, back-translated, pre-tested, and cross-culturally adapted before being administered to 205 individuals aged between 18–30 years from Medina, Saudi Arabia. Cronbach's alpha coefficient was used to test internal consistency, and the intraclass correlation coefficient (ICC) was used to assess test–retest reliability. Construct validity was assessed using factor analysis, and convergent validity was tested by comparing PIDAQ scores to the aesthetic components of the Dental Aesthetic Index (DAI) and Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC), while discriminant validity was assessed by comparing PIDAQ scores to participants' self-evaluation of orthodontic treatment need. Gender and age differences in the PIDAQ score were assessed. RESULTS: Cronbach's alpha coefficient was 0.940, corrected item-total correlation coefficients were between 0.509 and 0.719, and the ICC was 0.937. Principal component factor analysis extracted three domains, and factor loading ranged from 0.563 to 0.843. Total PIDAQ score and subscale scores had significant correlations with the DAI and IOTN-AC. The questionnaire discriminated well between participants who had a perceived need for orthodontic treatment and those with no perceived need. There were no significant age or gender differences in participants' PIDAQ scores. CONCLUSIONS: The Arabic version of the PIDAQ had excellent psychometric properties with sufficient reliability and validity to be used for the assessment of the orthodontic-related quality of life in young Arab adults.

OBJECTIVE: To assess the practice of using orthodontic brackets as tooth decorations among dental offices and patients in Jeddah, Saudi Arabia. MATERIALS AND METHODS: The study was a cross-sectional survey using 2 questionnaires. The first included 14 doctor questions where 300 dental offices in Jeddah, Saudi Arabia were contacted by phone. The second questionnaire included 22 patient questions where 50 patients who currently have or have had decorative braces answered the questions online. RESULTS: Out of 250 dental offices that responded, 91 offices (36.4%) answered “yes” to offering decorative braces. Most dentists use metal brackets (96.3%) on both the upper and lower arches (98.8%) and ligate a wire (83.8%) using colored elastomeric ligatures. Out of 50 patients who answered the patient questions, 28 patients (56%) were females and the mean age was 19.84 years (±2.32). 37 (74%) patients reported that their decorative braces were not placed by dentists and mostly by over the counter glue. Finally, 62% reported they were not satisfied, and 84% said they would not recommend getting decorative braces to their family and friends. CONCLUSION: Our results indicate that the use of decorative braces is prevalent, and most are not being placed by dentist. As healthcare providers, we are obliged to educate the public of potential harm that can result when decorative braces are used, to hopefully limit the spread of this unfortunate practice.

OBJECTIVE: To evaluate the orthodontic treatment outcome among patients with non-syndromic unilateral cleft lip and palate using the Peer Assessment Rating (PAR) index. MATERIALS AND METHODS: The retrospective study comprised a sample of 80 patients with unilateral cleft lip and palate (39 males and 41 females) with complete pretreatment and posttreatment orthodontic records. The patients were divided into two groups according to the treatment modalities. Group 1 (n = 55), nonsurgical (consisted of patients treated with comprehensive orthodontics) and Group 2 (n = 25), surgical (with presurgical orthodontics followed by maxillary advancement orthognathic surgery). PAR score was evaluated on pretreatment and posttreatment study models for both groups. RESULTS: The mean percentage change for the weighted PAR score of Group 1 and Group 2 was 76.79 ± 20.27% and 82.37 ± 11.38%, respectively. Out of the total sample of 80 cases; 62 (77.5%) cases were “greatly improved,” 16 (20%) cases were “improved,” and 2 (2.5%) showed “worse/no improvement.” Nearly 72.5% of cases in Group 1 and 88% in Group 2 were greatly improved. CONCLUSIONS: The reduction in PAR score in both groups was satisfactory as more than 70% of the patients were in the greatly improved category. The results of the PAR index revealed a high occlusal outcome of orthodontic treatment rendered by the department for patients with unilateral cleft lip and palate.

OBJECTIVE: To compare demineralization around orthodontic brackets cured by conventional method and transillumination method. MATERIALS AND METHOD: Sixty freshly extracted human premolar teeth were divided into four groups. Group 1: Brackets bonded with conventional method of bonding by curing labially for 40 sec. Group 2: Brackets bonded with transillumination method of bonding for 50 sec. Group 3: Brackets bonded with conventional method of bonding by curing labially for 20 sec followed by 30 sec of transillumination. Group 4: Brackets bonded with transillumination method of bonding for 30 sec followed by labial curing for 20 sec. Ground sections were prepared of each tooth and microleakage was evaluated using a binocular microscope at 40× magnification (Olympus BX53) and an image was taken using a digital camera (Olympus EPL3) connected to the microscope. The images were analyzed using Magnus Pro Image software. Scores were assigned to different degrees of microleakage at the demineralization zone around enamel-adhesive-bracket complex at the occlusal, middle, and gingival margins using linear measurement tool. Data obtained was subjected to statistical analysis using SPSS software (Version 20.0). Level of significance was kept at 5%. Intragroup comparison was done using Kruskal-Wallis test followed by Mann-Whitney U-tests for pairwise comparison. RESULTS: Group 4 showed least mean demineralization in occlusal, middle, and cervical areas as compared to other groups and the results were statistically significant (P < 0.05). CONCLUSION: Transillumination can be employed as a method synergistically with conventional curing to achieve minimum amount of demineralization during fixed orthodontic treatment.

OBJECTIVE: To determine the frequency of congenitally missing maxillary lateral incisors (LIs) and to find out its variability in relation to gender. MATERIALS AND METHODS: A retrospective study was carried out between January 2017 and December 2017. Orthopantomographs (OPGs) and lateral cephalographs record search of all orthodontic adolescent patients aged 12 to 18 years were taken from the archival records of the department. Orthopantomographs helped to diagnose the presence of unilateral/bilateral maxillary lateral incisors while the ANB angle was calculated from the lateral cephalographs to divide the subjects into various skeletal malocclusions. STATISTICAL ANALYSIS USED: The statistical analysis was done using the Statistical Package for Social Sciences (SPSS version 17.0). The frequencies were compared with the help of the Chi-square test. P<0.05 was considered statistically significant. RESULTS: The frequency of missing upper laterals among the male patients was 0.9%, however, 2.8% of the female patients were having missing maxillary lateral incisors. Based on gender, 62.16% had a bilateral expression of missing upper laterals, 16.21% had left unilateral expression, and 21.62% had right unilateral expression. Furthermore, skeletal class I malocclusion had a prevalence of 54.16% of bilateral missing lateral incisors in upper arch as compared to 40% of left unilateral expression and 37.5% of right unilateral expression whereas in skeletal class II malocclusion, the prevalence of right unilateral expression was 37.5% as compared to bilateral expression which was 33.33%. The left unilateral expression in skeletal class II malocclusion was found to be only 20%. The highest prevalence of missing laterals in skeletal class III malocclusion was left unilateral expression which was around 40%. The prevalence of right unilateral expression was 25% whereas the bilateral absence of upper laterals in skeletal class III malocclusion was 12.5%. CONCLUSION: The prevalence rate for congenitally missing upper lateral incisors in the orthodontic adolescent population aged 12 to 18 years was found to be 3.77% in the present study while females were found to have a greater percentage of agenesis of the upper lateral incisors (2.8%) as compared to the males (0.9%).
