Prevalence of dental anomalies in various malocclusions

Developmental dental anomalies have been associated with different malocclusions in various populations. This study verified this association in Brazilian non-syndromic orthodontic patients. The prevalence of dental anomalies was evaluated by examining 2,052 pretreatment records of orthodontic patients. Panoramic radiographs, study designs, intraoral photographs and medical history were collected in order to identify hypodontia, hyperdontia, microdontia, macrodontia, taurodontism, transposition, impaction, and ectopia. Epidemiological data and classification of malocclusion were also obtained. Data were analyzed using chi-square and Fisherʼs exact test (P < 0.05), and the prevalence ratio was obtained from cases that had a significant association between anomaly and malocclusion. The results showed that 27.4% of the patients evaluated had some dental anomaly, and most of them were white women aged 11-20 years. Ectopia, microdontia, impaction, and hypodontia were more prevalent in patients with Class I malocclusion. Macrodontia was the only anomaly associated with Class II division 1. Impaction was associated with Class III malocclusion, at a 1.84-times higher prevalence. In conclusion, impaction was correlated with Class I malocclusion; macrodontia showed association with Class II division 1; and impaction and ectopia were associated with Class III malocclusion in Brazilian orthodontic patients.

“…13,18 In contrast, Uslu et al 19 reported that Class II malocclusions are the most common (41.8%) in 900 Turkish subjects with permanent dentition. The mean prevalence of Class I malocclusion (76.9%) in our study was higher than in some other 13,19 studies and showed a decreasing trend towards the permanent dentition. Among Tanzanian and Finnish individuals, the prevalence of neutral occlusion also tends to decrease from primary to mixed dentition.…”

Distribution of sagittal occlusal relationships in different stages of dentition

2015

The aim of this study was to assess the distribution of sagittal occlusal relationships in different dentition periods in a Turkish sample group. In total, 1,110 patients (561 females, 549 males) aged 4.6-23 years were randomly chosen after intraoral clinical examination. The subjects were classified according to their sagittal occlusal relationships and four dentition stages -deciduous, early mixed, late mixed, and permanent dentition. The statistical significance of the occurrence of malocclusion types in dentition stages was evaluated by Chi-square and Fischer's exact tests. Class I malocclusion was observed at the highest rate in all dentition stages. Class III malocclusion was observed at the highest rate in the permanent dentition, whereas Class II malocclusion was observed at the highest rate in the late mixed dentition. The rates of Class I, II, and III malocclusions were similar in males and females. Our study reveals that the prevalence of malocclusion and need for orthodontic treatment has increased in the population towards the permanent dentition.

Although it was reported that there is no difference in dental anomalies in regard to age, 33 in this study age had a significant relation with dental anomalies.…”

These studies focused on younger populations and their age distributions were narrower than our study.…”

Aim: Oral mucosa, tongue, dentition and bone are important parameters for oral and systemic health care. A wide variety of lesions and conditions, either harmless or harmful, can affect the oral cavity. Identification and treatment of these conditions are an important part of oral health care. The aim of this study was to evaluate the general oral health status, by assessing the prevalence and types of mucosal, tongue, dental and jaw lesions, in a group of patients. Materials and methods: This study was conducted in a group of 314 dental outpatients. Participants' oral mucosal, tongue, dental, jaw lesions and their locations were recorded. Data were analyzed using logistic regression analysis. Results: Three hundred and fourteen patients (40.1% female, 59.9% male), 148 (47.1%) of whom exhibited one or more mucosal lesions, 40 (12.7%) tongue lesions, 242 (77.1%) one or more acquired dental conditions, 61 (19.4%) one or more dental anomalies, and 22 (7.0%) bone manifestations in the jaws. The most commonly detected mucosal lesions were Fordyce's granules (20.1%), linea alba buccalis (16.9%), melanoplakia (15.9%), and frictional keratosis (2.5%). Fissured tongue (8.0%), geographic tongue (1.6%), lingual varicosity (1.3%) and coated tongue (1.3%) were the most commonly determined tongue lesions. The most commonly detected dental anomalies were hypodontia (6.1%), microdontia (4.1%), dilaceration (4.1%), and enamel hypoplasia (2.5%). Exostoses (4.1%), enostoses (1.0%) and fibro-osseous lesions (1.0%) were the most commonly detected bone manifestations in the jaws. Conclusion: Oral mucosal and tongue lesions could be a sign of systemic diseases and also could form a base for oral cancers. In this study oral mucosal lesions and tongue lesions prevalence were high but fortunately all the detected conditions were harmless, benign conditions. This emphasizes the importance of familiarity, awareness, and differentiation of these lesions and conditions to avoid unnecessary treatments.Key words: Oral health, oral mucosal lesions, tooth anomalies, tongue lesions ÖZET Amaç: Oral mukoza, dil, dentisyon ve çene kemikleri ağız ve genel sağlığın önemli parametreleridir. Zararlı ve zararsız birçok lezyon ve durum oral kaviteyi etkileyebilir. Bu durumların tespit ve tedavileri ağız ve genel sağlığın önemli bir parçasıdır. Bu çalışmanın amacı, bir grup hastanın ağız sağlığı durumlarının mukoza, dil, diş ve çene lezyonlarının prevalans ve tipleri değerlendirilerek belirlenmesidir. Gereç ve yöntem: Bu çalışmaya diş hekimliği fakültesine başvuran 314 hasta katıldı. Katılımcıların oral mukoza, dil, diş ve çene kemiklerindeki lezyonlar ve bu lezyonların lokalizasyonları kaydedildi. Veriler lojistik regresyon modeli oluşturularak incelendi. Bulgular: Üç yüz on dört hastanın (%40.1 kadın, %59.9 erkek), 148'inde (%47.1) bir veya birden fazla mukoza lezyonu, 40'ında (%12.7) dil lezyonu, 242'sinde (%77.1) kazanılmış bir veya birden fazla dental patoloji, 61'inde (%19.4) bir veya birden fazla diş anomalisi ve 22'sinde (%7.0) kemik lezyon...
