“…A study carried out in the extreme north of Brazil showed a 27.2% prevalence of taurodontism, which is much higher than our findings and those from the literature. Taurodontism has as one of the possible causes the invagination of the Hertwig's epithelial root sheath, which is specified by a genetic determination, thus can differ according to the country region [4]. Another explanation is that the criteria used by the authors were not very strict for the determination of this dental anomaly.…”

Objective To verify the prevalence of dental anomalies in terms of number, position and shape, and the presence of bone alterations, through analysis of panoramic radiographs. Methods This study evaluated dental anomalies and bone alterations in children aged 6 to 12 years-old, detected on panoramic radiographies recorded in the radiographic database of the Federal University of Espírito Santo between 2012 and 2016. Clinical and demographic information were registered. Dental records were retrieved to obtain the medical history involving syndromes or other diseases that may interfere with the anomalies and alterations. Chi-square and exact Fischer’s statistical tests were performed. Results There were alterations in 83 out of 301 panoramic radiographs analyzed. There were 169 anomalies or alterations (mean of 2,04±1,38 anomalies/patient), involving 201 teeth. The most prevalent anomaly was tooth impaction (26.63%), which affected the canines more frequently, followed by hypodontia (24.26%), more often found in the second premolar, and both affected mostly females. Hyperdontia and radiolucent lesions showed the same prevalence (18.93%), the most affected teeth were those of the anterosuperior region and the first mandibular molars, respectively. The least prevalent anomalies were dilaceration (7.69%), taurodontism (2.37%) and radiopaque lesions (1.18%). Bone alterations were significantly more found in mandible and in the posterior region, which confirms the prevalence in the lower molars. Conclusion Although there was no statistically significant difference regarding sex, there was a high prevalence of anomalies and alterations in our study population, which indicates the importance of its diagnosis by means of a panoramic x-ray examination.

“…Frequency studies (prevalence and incidence) are very relevant due to genetic and ethnic variability. In addition, sample differences (age, sex, region, country) and diagnostic criteria are factors that indicate the need for various studies of this type [3][4][5].…”

Dental anomalies: prevalence and associations between them in a large sample of non-orthodontic subjects, a cross-sectional study

BackgroundTo analyze the prevalence and associations between dental anomalies detectable on panoramic radiographs in a sample of non-orthodontic growing subjects.MethodsFor this cross-sectional study, digital panoramic radiographs of 5005 subjects were initially screened from a single radiographic center in Rome. Inclusion criteria were: subjects who were aged 8–12 years, Caucasian, and had good diagnostic quality radiographs. Syndromic subjects, those with craniofacial malformation, or orthodontic patients were excluded and this led to a sample of 4706 subjects [mean (SD) age = 9.6 (1.2) years, 2366 males and 2340 females]. Sample was subsequently divided into four subgroups (8, 9, 10, and 11–12 year-old groups). Two operators examined panoramic radiographs to observe the presence of common dental anomalies. The prevalence and associations between dental anomalies were also investigated.ResultsThe overall prevalence of dental anomalies was 20.9%. Approximately, 17.9% showed only one anomaly, 2.7% two anomalies, while only 0.3% had more than two anomalies. The most frequent anomalies were the displacement of maxillary canine (7.5%), hypodontia (7.1%), impacted teeth (3.9%), tooth ankylosis (2.8%), and tooth transposition (1.4%). The lower right second premolar was the most frequent missing teeth; 3.7% had only one tooth agenesis, and 0.08% had six or more missing tooth (Oligodontia). Mesiodens was the most common type of supernumerary tooth (0.66%). Two subjects had taurodontic tooth (0.04%). Tooth transpositions and displacement of maxillary canine were seen in 1.4 and 7.5%, retrospectively (approximately 69 and 58% were in the 8 and 9 year-old groups, retrospectively). Significant associations were detected between the different dental anomalies (P < .05).ConclusionsThe results of our study revealed significant associations among different dental anomalies and provide further evidences to support common etiological factors.Electronic supplementary materialThe online version of this article (doi:10.1186/s12903-017-0352-y) contains supplementary material, which is available to authorized users.

Gigi insisif lateral maksila merupakan gigi yang memiliki bentuk dan ukuran yang bervariasi. Tujuan penelitian ini adalah untuk mengetahui frekuensi kelainan ukuran mesiodistal gigi insisif lateral maksila berdasarkan Woelfel. Metode: Jenis penelitian adalah deskriptif. Pengukuran mesiodistal gigi insisif lateral maksila menggunakan kaliper digital. Sampel sebanyak 35 mahasiswa diperoleh dengan teknik purposive sampling dilakukan pada ras Deuteromelayu. Hasil: Rata-rata ukuran mesiodistal gigi insisif lateral maksila pada regio 1 dan 2 adalah 6,28 mm (17,94%) dan 6,20 mm (17,71%). Nilai minimum dan maksimum regio 1 adalah 3,50-7,44 mm, sedangkan pada regio 2 adalah 3,46-7,77 mm. Terdapat 4 gigi insisif lateral maksila (11,42%), sepasang gigi (bilateral) insisif lateral maksila dan dua gigi insisif lateral maksila unilateral (kiri) yang memiliki kelainan ukuran. Jumlah yang mengalami kelainan pada gigi 12 sebanyak 1 gigi (2,85%), dan gigi 22 sebanyak 3 gigi (8,57%). Kelainan ukuran hanya terjadi pada 32 sampel perempuan (9,38%) dan termasuk kedalam golongan mikrodonsia (5,71%). Simpulan: Frekuensi kelainan ukuran mesiodistal gigi insisif lateral maksila berdasarkan Woelfel pada sub-ras Deuteromelayu sebanyak 3 orang dengan jenis kelainan mikrodonsia sejumlah 4 gigi dengan angka kejadian 2 gigi pada bilateral insisif lateral maksila dan dua gigi insisif lateral maksila unilateral. Kata kunci: Gigi insisif lateral maksila, abnormalitas ukuran mesiodistal. Frequency of mesiodistal size abnormality of maxillary lateral incisors based on Woelfel in the Deutro-Malays sub-race
