Prevalence of malocclusion among school children of Southern Saudi Arabia

Abstract

OBJECTIVE:To evaluate the status of occlusion among school children in city of Abha, Saudi Arabia.MATERIALS AND METHODS:The current study was based on the clinical examination of 1998 Saudis (mean age 14.13 ± 0.99 years) who were randomly selected by a multi-stage random sampling technique from the city of Abha. The occlusal parameters recorded in this study were molar and canine relationships, overbite, overjet, crowding, spacing, anterior open bite, anterior crossbite, posterior crossbite, and scissors bite using gloves, light source, mouth mirror, and ruler.RESULTS:Class I molar relationship was observed in 1219 (61%) of the total sample, while Class II and III molar relationships were observed in 326 (16.3%) and 154 (7.7%), respectively. Class I–III canine relationships were seen in 1255 (62.8%), 231 (11.6%), and 112 (5.6%) of the sample, respectively. Normal overbite was found in 1490 (74.6%) of cases, while 1515 (75.8%) had normal overjet. The most prevalent malocclusion trait was crowding (26.6%), followed by spacing (20.6%), increased overjet (19.5%), increased overbite (19.4%), posterior crossbite (8.5%), and anterior open bite (6.1%).CONCLUSIONS:Crowding was the highest occlusal trait in frequency followed by spacing, increased overjet, and increased overbite. Class I molar and canine relationships, normal overjet, and normal overbite were frequent findings among Saudi adolescents in Abha city.

Optimal Position of Attachment for Removable Thermoplastic Aligner on the Lower Canine Using Finite Element Analysis

“…After deriving the optimal shapes of attachments for each orthodontic treatment situation based on the results of the FEA of simplified orthodontic treatment model, a 3D finite element model was simulated using the mandibular CBCT image used in previous studies (Figure 5a) [20,21]. The study results of Asiry et al [32] showed highest prevalence of molars and canines. Also, Kravitz et al [33] reported that in the teeth movement using only RTA, the extrusion, intrusion and rotation of mandibular canine was less accurate than maxilla canine.…”

A Comparison of Craniofacial Characteristics between Two Different Adult Populations with Class II Malocclusion—A Cross-Sectional Retrospective Study

“…Malocclusion can occur due to a number of causes commonly divided into genetic and environmental factors [ 4 ]. The etiological complexity of malocclusion lies not only in variable and uncertain expression of certain traits, but also in the broad range of craniofacial alterations present within the same malocclusion phenotype in concerned individuals [ 5 , 6 ]. Despite this intricacy, the study of malocclusion in different populations is cornerstone in understanding the biology underlying the growth of the craniofacial complex [ 6 ].…”

“…Class II malocclusion is one of the most prevalent malocclusions encountered in orthodontic practice in most societies [ 4 , 5 , 6 , 7 ]. Understanding the characteristics of vertical skeletal and dental parameters in patients with Class II malocclusion can help us identify the patterns and variations in the expression of this malocclusion.…”

Review on Anterior Crossbite Diagnosis and Management Approach in Paediatric Age, Literature Review

“…Children with specific malocclusion characteristics tend to have greater issues with psychology and social relationships as they grow up, and their quality of life decreases as well (Yu et al, 2019). A cross-sectional study conducted in Abha, Saudi Arabia targeting teenagers found 1219 (61%) of the entire sample had a Class I molar relationship, whereas 326 (16.3%) and 154 (7.7%), respectively, had Class II and III molar relationships (Asiry and AlShahrani, 2019). This paper aimed to review the possible related etiologies to this disease, how to evaluate and manage it.…”
