Abstract:This cross-sectional study aimed to evaluate the primary canine and the primary molar relationship in 205 (90 girls and 115 boys) three to six year-old Turkish children with the primary dentition in centric occlusion according to gender and age. In terms of the molar relationship, Class I was represented by 88.29% of all children who agreed to participate in the study, followed by Class II (7.31%), and Class III (4.4%). In terms of the canine relationship, Class I was represented by 87.8% of the sample, follow… Show more
“…In a study by Yilmaz et al ., on Turkish children, the percentage of children having flush terminal plane remained high for all the age groups between 3 to 6 years. [5] But, in the study of Aderson AA, mesial step relationship was predominant in both the African American and European children. [7] However, increased percentage of distal step (33.1%) is been reported in the study of Keski-Nisula et al ., on Finland children.…”

Background:To assess the prevalence of malocclusion and to determine the different occlusal characteristics in primary dentition of 4 to 6 years old children in India.Materials and Methods:The target population comprised 4 to 6 years old children attending different nursery, kindergarten and primary schools of Bagalkot city. Stratified cluster random sampling procedure was executed to collect the representative sample. Each subject was assessed for various occlusal characteristics.Results:Occlusal characteristic found were flush terminal plane (52.5%), class I canine relationship (84%), maxillary developmental spaces (35.4%), primate spaces in maxilla (47.6%), mandibular crowding (4.6%), mandibular midline shift (5.6%), anterior multiple tooth crossbite (1.3%), scissors bite (0.6%), anterior open bite (1%), over bite of 0-2 mm (81.6%) and overjet of 0-2 mm (84.5%). The age wise difference for the occlusal characteristics was statistically significant.Conclusions:The data revealed that most of the children had malocclusion. This highlights the importance of identifying children who are in need of orthodontic treatment for dental health or aesthetic reasons.

“…4 One of the most common problems of the deciduous period is determining the occlusions. 5 Occlusion plays an important role in the mastication, speech and aesthetic systems. 6 The occlusion of the deciduous teeth has another important role, which can predict permanent dental occlusion.…”

“…7 Early dentin inclusion is influenced by several factors, namely the loss of tooth structure that can affect mesiodistal and occluso gingival space, have physical or mental disabilities and developmental defects, the presence of dental anomalies, and have bad habits. 5,[8][9][10][11] The development of the occlusion of the deciduous tooth begins to form at the age of 3 years because at that age the primary teeth have perfectly erupted. 11 The age of 3 years is included in preschool age.…”

“…15 One of the effects caused by premature loss of the second molar is the difficulty of determining the plane terminal relationship since the relation sees the mesiodistal relationship between the distal surface of the upper and lower jaw molar at the occlusion of centric position. 5,7 The term plane relations can be categorised into three types, which are flush terminal plane, mesial step, and distal step. 16 One of the ideal developmental characteristics of the occlusion of the first deciduous teeth is that if the second molar relationship is categorised as flush terminal plane.…”
Introduction:The primary second molar relation is also called the terminal plane, which is the relation between the distal surface of the maxillary and mandibular second primary molars in a centric occlusion position. One of the most important characteristics of the ideal occlusion development on the primary dentition is if the primary second molar relation classified as the flush terminal plane. This relation plays a significant role in determining the relation in permanent molar because the eruption of the first permanent molars are guided by the distal surface of the maxillary and mandibular second primary molars. The purpose of this study was to found out the clinical description of the primary second molar relation among the preschool-aged children in four kindergartens in Banda Aceh. Methods: This study was a descriptive study with cross-sectional study approach. The subject selection method was performed with a purposive sampling method involving as much as 37 subjects, which were students of State Kindergarten of Pembina 1, State Kindergarten 2, State Kindergarten 3, and State Kindergarten of Adidarma 4, Banda Aceh. The examination was performed by using the intraoral mirror when the teeth were in the centric occlusion position. Decisions regarding the primary second molar relation were made by the bilateral occlusion (left and right). Results: The flush terminal plane was found in 45.9% of all respondents, the mesial step was 54.1%, and the distal step was 0.0%. Conclusion: The primary second molar relation among preschool-aged children generally had the mesial step.
ObjectivesThe aim of this article is to establish a comprehensive nationwide prevalence of malocclusion traits on the sagittal, vertical, and transverse planes of space in the Turkish population.Material and MethodsA systematic search of PubMed, Scopus, and Web of Science was supplemented by manual searches of Google Scholar and the reference lists of included studies. Original Turkish health studies of any age were included. Strengthening the Reporting of Observational Studies in Epidemiology assessed study quality and bias (STROBE). Sagittal, vertical, and transverse malocclusion features were retrieved and gathered.ResultsEleven studies were selected from 434 titles. Two studies showed a high risk of bias, eight low and one moderate. Thirteen thousand two hundred seventy‐one individuals were investigated from early childhood to late adulthood. Most studies were sampled from universities and dental (nonorthodontic) clinics. The pooled malocclusion prevalence was 56% for Class I (95% confidence interval (CI): 44−68%), 31% for Class II (CI: 6–42%), and 11% for Class III (CI: 21–37%). The other common types of malocclusions were crowding (41%, CI: 18–65%), overjet (34%, CI: 21–50%), negative overjet (13%, CI: 7–20%), and crossbite (11%, CI: 7–15%). Additionally, there was no significant difference in Class I (relative risk [RR] = 1.00, [0.96–1.05]), Class II ([RR] = 0.97, [0.92–1.03]), and Class III ([RR] = 1.08, [0.96–1.225]) malocclusion by gender.ConclusionsThis study showed Class I malocclusion has a high prevalence among the Turkish population followed by Class II and Class III malocclusions. In addition, crowding and overjet were the most prevalent malocclusions among Turkish individuals. There were no significant differences in the prevalence of malocclusions between males and females.
