“…In our results, we found a significant ( P < 0.001), moderate, linear correlation between the DAI score (severity of the malocclusion) and the ABO-DI score (case complexity). Similar results were found for DAI (r = 0.5523; P < 0.001) and ICON (r = 0.521; P < 0.001) scores with respect to treatment need (Onyeaso, 2007; Vidaković et al, 2018). In another study, the researchers found a moderate agreement between the ICON and dental health component of the IOTN (Borzabadi-Farahani et al, 2011).…”

Objective: To establish the association between malocclusion severity and orthodontic case complexity as assessed by the Dental Aesthetic Index (DAI) and the American Board of Orthodontics Discrepancy Index (ABO-DI), respectively. Design: Cross-sectional study. Setting: Pre-treatment dental casts and radiographs from 500 individuals (294 women and 206 men; mean age = 26.06 ± 11.58 years) were randomly selected from the orthodontics department of a private university. Methods: Malocclusion severity was assessed using DAI and case complexity was evaluated with ABO-DI. Three previously calibrated operators performed the measurements. Spearman’s correlation analysis, Mann–Whitney U test, Kruskal–Wallis test and a linear generalised model were used for statistical evaluation ( P < 0.05 was considered significant). Results: Although the correlation (r = 0.45; P < 0.0001) between malocclusion severity and case complexity was moderate, strong evidence of an association ( P < 0.001) between dichotomised DAI and ABO-DI total scores was observed. The linear generalised model showed that for each point of increase in DAI score, the ABO-DI score increased an average of 0.3624 points ( P < 0.0001). Conclusion: An association between malocclusion severity and case complexity is suggested. A linear generalised model could be used to predict the complexity of the case from the malocclusion severity (DAI score).

“…[6][7][8][9][10][11][12][13] e previous research suggested that the ICON could replace the PAR and IOTN (15) since the ICON was developed from the PAR and IOTN and correlated highly with both of these indices. [14] Khandakji et al [15] recently concluded that the dental health component (DHC) and esthetic component (AC) of IOTN, ICON, and PAR reliably captured treatment need. e index ICON comprises five weighted measurements and owes some of its structure to IOTN and PAR.…”

Objectives: The purpose of the study was to epidemiologically assess the prevalence of malocclusion and orthodontic treatment need in school-aged adolescents in Dubai using the Index of Complexity, Outcome, and Need (ICON). Null hypothesis tested was no significant differences in ICON scores among Dubai students as a function of gender or geographic/ethnic background. Materials and Methods: The sample was 17,763 adolescents with nearly equal by gender; India and the United Arab Emirates were represented about the same. Scores for malocclusion from Peer Assessment Rating (PAR) index evaluations combined with the esthetic component of the Index of Orthodontic Treatment Need (IOTN) comprised the ICON score. Results: Male ICON scores were significantly greater than female scores. Three scores contributing to ICON were significantly higher in males, i.e., buccal anterior-posterior occlusion, incisor overbite, and esthetic component. ICON scores for South Asia were significantly higher than the Middle East, i.e., 59.9 versus 52.4, P = 0.000. ICON scores were no different for the UAE males and females but otherwise significantly different (>) as follows: Indian males > Indian females > UAE males = UAE females. Conclusions: Dubai school-aged adolescents treatment need is the same for the UAE males and females, but there is a significantly greater orthodontic treatment need for males and females from India.

“…The final ICON score was divided into malocclusion complexity grades (<29 = easy, 29–50 = mild; 51–63 = moderate, 64–77 = difficult, >77 = very difficult). A cutoff point of 43 was set to mark a definite need for orthodontic treatment [ 41 ].…”

Environmental Cadmium Exposure and Dental Indices in Orthodontic Patients

et al. 2021

Background. Previous studies have shown that environmental cadmium exposure could disrupt salivary gland function and is associated with dental caries and reduced bone density. Therefore, this cross-sectional study attempted to determine whether tooth decay with tooth loss following cadmium exposure is associated with some dental or skeletal traits such as malocclusions, sagittal skeletal pattern, and tooth decay. Methods. Between August 2019 and June 2020, 60 orthodontic patients with no history of previous orthodontics, functional appliances, or surgical treatment were examined. The patients were stratified into two groups according to their urine cadmium concentrations: high (>1.06 µg/g creatinine, n = 28) or low (<1.06 µg/g creatinine, n = 32). Results. The patients were 25.07 ± 4.33 years old, and most were female (female/male: 51/9 or 85%). The skeletal relationship was mainly Class I (48.3%), followed by Class II (35.0%) and Class III (16.7%). Class I molar relationships were found in 46.7% of these patients, Class II molar relationships were found in 15%, and Class III molar relationships were found in 38.3%. The mean decayed, missing, and filled surface (DMFS) score was 8.05 ± 5.54, including 2.03 ± 3.11 for the decayed index, 0.58 ± 1.17 for the missing index, and 5.52 ± 3.92 for the filled index. The mean index of complexity outcome and need (ICON) score was 53.35 ± 9.01. The facial patterns of these patients were within the average low margin (26.65 ± 5.53 for Frankfort–mandibular plane angle (FMA)). There were no significant differences in the above-mentioned dental indices between patients with high urine cadmium concentrations and those with low urine cadmium concentrations. Patients were further stratified into low (<27, n = 34), average (27–34, n = 23), and high (>34, n = 3) FMA groups. There were no statistically significant differences in the urine cadmium concentration among the three groups. Nevertheless, a marginally significant p-value of 0.05 for urine cadmium concentration was noted between patients with low FMA and patients with high FMA. Conclusion. This analysis found no association between environmental cadmium exposure and dental indices in our orthodontic patients.
