“…Further, Yuen et al (18) and Ling and Wong (19) suggested that in the Asian population, the mesiodistal width of the mandibular anterior teeth is larger compared to the Caucasians. A higher Bolton's value obtained in some studies conducted in the Malaysian population coincides with the finding of crowding in our study (13). However, contrasting reports were found in a study conducted on Lithuanian schoolchildren where crowding was found to be more in the maxilla (44.1%) in comparison to the mandible (40.3%) (20).…”

“…Crowding and spacing in the dental arch are two of the common causes of malocclusion for which individuals seek orthodontic treatment. The prevalence of crowding and spacing varies according to differences in population across the world, and knowledge of this provides valuable insight into the treatment of malocclusion in line with the standard cephalometric norms of that population (13). In our study, crowding was a feature more common in the mandibular arch in our study population, which comprised 80% of the study population.…”

Malocclusion is an abnormal occlusion with regard to the position of the teeth and shows varied prevalence in different parts of the world. Crowding and spacing of teeth are two common features of malocclusion and are described as a lack or excess of space between the teeth. This study was conducted to evaluate the prevalence of crowding and spacing of teeth and their severity among Malaysian adults aged 18–25 visiting our institution, as well as their association with gender. A total of 150 adult patients were evaluated for crowding and spacing using the Boley caliper intra-orally. The severity of crowding and spacing was also noted. The study included Malay (70%), Chinese (25%), and Indian (5%) participants. Descriptive statistics were done and it was observed that crowding was more common in the mandibular arch (80%), whereas spacing was a common malocclusion found in the maxilla (14%). Based on the severity of crowding, it was observed that mild crowding (1-3 mm) was most frequent in both the maxilla (45%) and mandible (53%). However, in terms of spacing, moderate spacing (4-6 mm) (5.3%) was common in the maxilla; whereas in the mandible, mild spacing (1-3 mm) (9.3%). The Chi square analysis did not reveal any significant association between crowding and spacing with gender. Based on these results, it can be concluded that crowding is a common malocclusion affecting the mandibular arch, whereas spacing is common in the maxilla in the young Malaysian population visiting our institution. Both of these malocclusions were of the milder type and did not show any association with gender in our study population Studies conducted on a larger population are required to determine the association of these traits between genders and races in our population.

“…In this study, the prevalence of Class I skeletal pattern was 41.3%, Class II: 46.1%, and Class III: 12.6%. Based on the literature reviews, the prevalence of Class I malocclusion in the Malay population was reported to be in the range of 33.3% to 39.3%, Class II: 12% to 30%, and Class III: 12.2% to 48.7% (6)(7)(8). The large variation between different studies was due to different sampling methods.…”

“…This type of sampling was why the prevalence of Class I skeletal pattern was lower in this study which used the same convenience sampling method by recruiting only potential orthodontic patients from clinic settings. However, it was worth noticing that while the previous studies aforementioned had investigated the prevalence of malocclusion of the Malaysian and the Malay population, all had used Angle's Classification to classify the occlusal status of the population, meaning that the prevalence represented more of the dental origin rather than the underlying skeletal pattern (6). Therefore, only a little comparison could be made with these studies due to different categorisation methods.…”

“…Although few epidemiological studies were done in Malaysia, those studies determined the prevalence of malocclusion instead of skeletal patterns in all three ethnicities (6,7). In the Malay population (8), all the studies used Angle's molar relationship classification to classify malocclusion, which is a different method and results in the only type of malocclusion being reported from this study.…”

Prevalence studies of malocclusion should distinguish how skeletal classification was done because of the moderate correlation that exists between dental arches and skeletal patterns. The validity of using the ANB angle as a diagnostic tool to determine skeletal patterns remains questionable. This study aimed to determine the prevalence of skeletal patterns in the Malay population, their association with gender and age groups, and whether the ANB angle is a highly correlated variable in diagnosing skeletal patterns radiographically by using Principal Component Analysis (PCA). Two thousand one hundred eighty-two lateral cephalograms of Malay patients were digitally traced. Respective skeletal patterns were determined using the ANB angles. Descriptive analysis was used to describe the prevalence, whereas the association with gender and age groups were determined using the Chi-Squared and Fisher's Exact tests. PCA was done on all commonly used cephalometric variables in Class III samples. The prevalence for the Class I, Class II and Class III skeletal patterns were 41.3%, 46.1%, and 12.6%, respectively. A significant association was found between gender and skeletal patterns (p = 0.012). Most of the significant variables in principal component (PC) 1 were vertical measurements. ANB angle was not captured in the first five PCs. Class III skeletal pattern was significantly less prevalent in the Malay population when compared to other skeletal patterns, especially in males. Vertical, sagittal cephalometric measurements and incisor angulation variables were more highly correlated than the ANB angle and, therefore, may be more useful to diagnose the Class III skeletal pattern.
