Prevalence and Characteristics of Supernumerary Teeth in Pediatric Patients: A Retrospective Study

Abstract Background: Supernumerary teeth are a dental anomaly that can impact oral health, yet their prevalence and characteristics in pediatric populations remain underexplored. This retrospective study aimed to investigate the occurrence and attributes of supernumerary teeth in children aged 4–14 years. Methods: Medical records including panoramic radiographs of 3127 pediatric patients were reviewed. Data included patient demographics and supernumerary tooth characteristics (number, location, eruption status, morphology, primary/permanent, sagittal position, and orientation) and were subjected to statistical analysis using Fisher’s exact and Chi-square tests (P < 0.05). Results: Among the 3127 patients, 87 (2.8%) showed supernumerary teeth, with a male predominance (56.3%). Supernumeraries were most common in the mixed dentition (58.6%), followed by permanent dentition (26.5%) and primary dentition (14.9%). The majority had a single supernumerary tooth (83.9%), resulting in a total of 101 supernumeraries. Conical supernumeraries were the most common (65.3%), followed by tuberculate (20.8%) and supplemental (13.9%) types. Palatal placement was predominant (78.2%), whereas 18.8% were on the alveolar arch, and 3% were labial. Most were normally oriented (78.2%), with 13.9% inverted and 7.9% angular. Eruption status indicated that 63.4% were erupted, whereas the rest were impacted. Conclusion: This retrospective study revealed a 2.8% prevalence of supernumerary teeth among pediatric patients, with a male predominance.

Amaç: Bu çalışmanın amacı Türkiye’nin doğusunda Erzincan bölgesinde pedodonti kliniğine başvuran çocuk hastalarda süpernümerer dişlerin prevalansını ve özelliklerini belirlemek, neden oldukları komplikasyonları araştırmak ve güncel literatürler ile kıyaslama yapmaktır. Materyal ve Metot: Bu retrospektif çalışmada Ocak 2019-Ocak 2020 tarihleri arasında Erzincan Binali Yıldırım Üniversitesi Diş Hekimliği Fakültesi’ne başvuran 4-14 yaş arası 3825 çocuk hastanın klinik ve radyografik verileri incelendi. Süpernümerer dişleri olan her hasta için demografik veriler (yaş,cinsiyet), süpernümerer diş sayısı, sürme durumu, morfoloji, pozisyon, bulundukları dişlenme dönemleri ve süpernümerer dişlerle ilişkili komplikasyonlar kaydedildi. Toplanan veriler istatistiksel olarak analiz edildi. Bulgular: Çalışma sonucunda 51 hastada (%1,34) toplam 64 adet süpernümerer diş tespit edildi. Süpernümerer dişler 1.8:1 erkek kadın oranı ile erkeklerde daha fazla görüldü (p <.001). Süpernümerer diş sayısı ile hastaların cinsiyeti arasında bir ilişki gözlemlenmedi. Supernümerer diş sayısı 39 vakada bir, 11 vakada iki ve sadece 1 vakada 3 idi. Tespit edilen 64 süpernümerer dişin 40 tanesi karışık dişlenme döneminde, 21 tanesi daimi dişlenme döneminde ve 3 tanesi ise süt dişlenme döneminde bulunduğu gözlemlendi. Çoğu süpernümerer dişin maksillada bulunduğu tespit edilirken morfolojik olarak konik şekilli süpernümerer dişler en sık rastlanan grup olduğu görüldü. Süpernümerer dişlerin %78,1’i dikey pozisyonda iken %11’i yatay pozisyonda olduğu gözlemlendi. İncelenen vakalarda süpernümerer dişlerin %46,9’u asemptomatik iken en sık neden oldukları komplikasyon ise %35,9 oranla daimi dişlerin sürmelerini engellemeleriydi. Sonuç: Süpernümerer dişlerin insidansı incelenen Türk popülasyonunda %1,34’tür ve gelişmekte olan dental oklüzyona zarar verebilecek birçok komplikasyona neden olabilmektedirler. Süpernümerer dişler hakkında elde edilen bu bilgiler, çocuk diş hekimlerine erken tanı ve müdahale konusunda yardımcı olabilir.

The Prevalence and Morphology of Supernumerary Teeth in Children With Nonsyndromic Cleft Lip and Palate

Cleft lip with or without cleft palate (CL/P) is congenital deformity associated with hyperdontia. To determine the prevalence and characteristics of supernumerary teeth in patients with CL/P. Retrospective descriptive and correlation clinical study. One hundred thirteen children with cleft (age ranged 9.3-19.2; 67 males and 46 females) treated in Clinic of Congenital Facial Deformities Medical University of Lublin were included in the study. Records evaluation was conducted regarding age, gender, cleft type (Q36, Q37-International Classification of Diseases 10th revision), cleft side, and incidence of supernumeraries. In all supernumerary teeth, size, shape, and developmental degree were analyzed and correlation between the incidence of hyperdontia with different variables was checked. Correlations were detected using chi-square and the Yates correction. The majority of the examined group were males-59.29% with Q37 (67.26%) and the cleft on the left side (62.83%). Hyperdontia was noted in 26.55%. Only upper lateral incisors were affected. They usually had atypical shape (56.67%), reduced size (83.33%), and delayed development (56.67%). The prevalence of supernumerary permanent teeth in patients with cleft was higher than in the general population. Anomaly was more frequent in male patients and occurred mainly on the cleft side. The severity of the cleft did not influenced the frequency of supernumerary teeth, their shape, size, and developmental degree. Supernumerary teeth were characterized by reduced crown size, abnormal structure, incorrect inclination, and delayed development phase.

Prevalence of supernumerary teeth among a sample of patients attending college of dentistry in Erbil, Iraq (A Retrospective study)

Background and Objectives: A supernumerary tooth is an additional tooth to the normal series and can be located in almost any region of the dental arch. The objective of the study was to investigate the prevalence of supernumerary teeth and the distribution of the cases according to the demographic data and characteristics among patients attending a College of Dentistry in Erbil, Iraq. Methods: This descriptive and retrospective study was performed on 1233 patients (658 males 53.4% and 575 females 46.6%) ranging in age from 3 to 14 years old during the period 20172018. The characteristics of supernumerary teeth were noted and diagnosed during the clinical and radiographic examination. The demographic variables including age and gender was recorded for each patient. During statistical analysis Fisher’s exact test was used. p value of less than .05 was considered statistically significant. Results: Only eight supernumerary teeth were detected in 1233 patients (0.6 %). 7 patients were males and 1 patient was female with a 1.14:1 male/female ratio (p =0.089). Among supernumeraries: most of them 5 teeth (62.5%) were found in the maxillary anterior, and 7 teeth (87.5%) were conical in morphology. All the supernumerary teeth occurred as single tooth within the oral cavity. Regarding eruption status within the arch, all supernumerary teeth (100%) had erupted. All supernumerary teeth (100%) were extracted. Conclusion: The identification of this anomaly provides a clue towards the possibility of any complication, pathologies, other related dental anomalies, syndromes and familial association in Erbil, Iraq.

Supernumerary Teeth: A Retrospective Cross-Sectional Study from Palestine

Objective: To investigate the prevalence and characteristics of supernumerary teeth among patients attending the students' dental clinics at the Faculty of Dentistry of the Arab American University, Jenin, Palestine. Material and Methods: This is a descriptive, cross-sectional, retrospective study of 1970 digital panoramic radiographs of patients, age ranging between 12 and 50 years. The radiographs and dental records were reviewed for supernumerary teeth. For each patient with supernumerary teeth, were recorded the demographic variables, number, location, eruption status, type, and morphology, the developmental stages. Descriptive statistics were performed and results were tabulated. Results: Supernumerary teeth were detected in 17 subjects (0.86%), of which 13 were males and 4 were females with a male to female ratio of 3.25:1. Of the 17 patients, 64.7% had one supernumerary tooth while the others had two. The majority (78.3%) of the supernumeraries were located in the maxilla. Around 56.5% of the supernumeraries found in this study were located in the premaxilla. Half of the supernumeraries (52.2%) were erupted, and 47.8% were impacted. Mesiodens was the most frequently seen supernumerary teeth followed by distomolars and premolars. Most of the supernumeraries were fully developed, while 21.7% displayed only crown formation. Conclusion: The prevalence of supernumerary teeth in the study sample was found to be 0.86% and the most frequent type was mesiodens. Supplemental morphology was found to be the most common form of supernumerary teeth.

Prevalence and Characteristics of Supernumerary Teeth in Israeli Orthodontic Patients.

Supernumerary teeth are one of the most common anomalies in the human dentition, found most frequently in the maxillary anterior region causing impaction or displacement of the adjacent permanent teeth. The purpose of this retrospective study was to determine the prevalence and characteristics of supernumerary teeth in orthodontically treated patients. Pre-treatment facial and intraoral photographs, study models, panoramic and periapical radiographs of 3,000 consecutively treated orthodontic patients (mean age 12.2 years) from the Department of Orthodontics Tel Aviv University, were examined to detect supernumerary teeth in both arches. They were recorded according to gender, age, number, location, position and morphology. Thirty-six patients, 22 (61%) males and 14 (39%) females with 50 supernumerary teeth, of which 42 (84%) were found in the maxillary anterior region, and 8 (16%) in the mandible, presenting a prevalence of 1.2%. A prevalence of 1.2% was found in our study. The most common supernumerary tooth is mesiodens located at the maxillary anterior region. The characteristics of supernumeraries were based on their morphology, location and position. The most frequent complications caused were rotations, displacement and arrested eruption of maxillary incisors.

Prevalence and characteristics of supernumerary teeth in patients from Ras Al Khaimah: A retrospective study from a Teaching Dental Hospital in the UAE

Context: Supernumerary teeth are teeth that exceed the normal dental formula. They have variable characteristics and may cause a number of clinical complications. In the Middle East, a prevalence of 0.3%–2.14% has been observed; however, the number of studies of this condition is limited in the region. Aims: This study aimed to examine the prevalence and characteristics of supernumerary teeth in patients from Ras Al Khaimah with consideration of demographic variations. Setting and Design: The study was performed at RAK College of Dental Sciences Dental Clinic. The radiographic database from two consecutive years was used as study sample. Subjects and Methods: A total of 2925 panoramic radiographs were analyzed to identify supernumerary teeth, and demographic-clinical data were extracted from patient files. Statistical Analysis: Data were analyzed using nonparametric tests. P ≤ 0.05 was considered statistically significant. Results: A prevalence of 0.75% was observed. Affected patients were predominantly South Asian males. The teeth were mostly supplemental, para-premolars, and impacted with low incidence of distomolars and no difference in occurrence in the maxilla or mandible. Occurrence of multiple supernumerary teeth was low and restricted to one jaw. Conclusions: This study suggests that one of every 133 patients will have impacted supernumerary teeth that can be expected in the premolar area of the maxilla/mandible, which should be considered when planning community oral health diagnosis and dental treatment strategies.

Characteristics of Supernumerary Teeth in Nonsyndromic Population in an Urban Dental School Setting

The purpose of this study was to analyze the clinical records of all patients evaluated for supernumerary teeth at the University of Illinois-Chicago Department of Oral and Maxillofacial Surgery postgraduate clinic from January 1, 2010 to October 31, 2015 to determine the demographics of impacted supernumerary teeth among different ethnicities in the city of Chicago. A retrospective case series was completed on patients eligible for inclusion in the study who had a diagnosis of at least 1 full bony impacted supernumerary tooth (D7240). Other variables evaluated included date of surgical intervention, age at time of treatment, gender, ethnicity, location and number of supernumerary teeth present, and family history of supernumerary teeth. There were 459 male and 308 female patients (male-to-female ratio, 1.5:1). Patient ages ranged from 4 to 51years (average, 13.1) at the time of surgery. Five hundred seventy-three patients (74.7%) were of Hispanic descent. Supernumerary teeth were found most frequently in the maxilla (69.9%), specifically in the central incisor region (526 teeth; 51.2%). Of the responding patient sample (258 patients), 53 patients (20.5%) reported a family history of supernumerary dentition. Of these 53 patients who reported a family history of supernumerary dentition, 37 (69.8%) were of Hispanic descent. Most of these Hispanic patients (83.8%) originated from Mexico. The incidence of supernumerary teeth is higher in male patients (male-to-female ratio, 1.5:1), and these teeth are most frequently found in the maxilla (69.9%), specifically the central incisor region (51.2%). A large percentage of patients (20.5%) also had first-degree relatives with a supernumerary dentition, and this fact might warrant further investigation into the possible genetics responsible for the formation of supernumerary teeth.

Information on the demographic variables for each patient, including age and gender, were colleceted.Materials and Methods:All supernumerary teeth were classfied under several titles such as location, position, morphology, eruption, clinical complications, and treatment protocols. The data obtained were subjected to statistical analysis. Chi-squared test was used to determine differences in distribution of supernumerary teeth when stratified by gender. The statistical significance was established by confidence interval of 95% (P ≤ 0.05).Results:123 (2.14%) affected patients (69 females and 54 males) were observed with a female:male ratio of 1.28:1 (P < 0.05). One hundred and fifty-six supernumerary teeth were detected in all affected patients.Conclusion:Supernumerary teeth may be observed in adults patients with a similar frequency (2.14%) as in children and young adolescents, and clinicians should take measures and examine all patients carefully even at older ages.

Characteristics of supernumerary teeth among nonsyndromic dental patients

Background/purposeA literature review reveals limited data for supernumerary teeth in Taiwan. Therefore, this study aimed to analyze the characteristics of nonsyndrome associated supernumerary teeth in a Taiwan population. Materials and methodsA retrospective study analyzed 6423 nonsyndromic patients (3300 males and 3123 females; age range: from 4 years, 7 months to 76 years, mean age: 25.03 ± 16.32 years). Diagnosis of supernumerary teeth was based on panoramic radiographic examination. Chi-square test, Chi-square test for trend, and multiple logistic regression analysis were used for statistical analysis. ResultsThe prevalence rate was 2.6% (248 supernumerary teeth in 167 patients), with a male predominance (1.69:1; P < 0.001). Most supernumerary teeth were single (67.66%), conical (47.98%), and unerupted (79.84%). Supernumerary teeth also tended to be located in the premaxilla (52.82%), fully developed (54.44%), normally oriented (59.27%), sagittally placed in a palatal/lingual position (76.96%), and adjacent to the root and root apex of permanent teeth (63.71%). ConclusionThe prevalence of supernumerary teeth in this study was 2.6%, the most frequent location being at the anterior maxilla. Numerous factors should be considered when evaluating supernumerary teeth. Specifically, the demographic profiles of patients with supernumerary teeth provide useful epidemiological information.

Majority of patients had a single erupted supernumerary oriented straight in the arch. Patients in mixed dentition stage reported with maximum number of supernumerary teeth. The prevalence of supernumerary teeth in non syndromic South Indian paediatric population is 1.24% with slight male predilection and conical mesiodens being the commonest.

Supernumerary teeth in Nepalese children.

Objective. The objectives of the present study were to investigate the prevalence and characteristics of supernumerary teeth in a patient sample of Nepalese children. Study Design. A survey was performed on 2684 patients (1829 females and 1035 males) ranging in age from 6 to 14 for the presence of supernumerary teeth. For each patient with supernumerary teeth the demographic variables (age and sex), number, location, eruption status, and morphology were recorded. Descriptive statistics were performed. Results. Supernumerary teeth were detected in 46 subjects (1.6%), of which 26 were males and 20 were females with a male : female ratio of 1.3 : 1. The most commonly found supernumerary tooth was mesiodens followed by maxillary premolars, maxillary lateral incisor, and mandibular lateral incisor. Of the 55 supernumerary teeth examined, 58.18% (n = 32) had conical morphology, followed by tuberculate (30.90%, n = 17) and supplemental (10.90%, n = 6) forms. The majority of the supernumerary teeth were erupted (56.36%, n = 31). Conclusion. The prevalence of supernumerary teeth in Nepalese children was found to be 1.6%, the most frequent type being mesiodens. Conical morphology was found to be the most common form of supernumerary tooth.

Lateral incisor agenesis, canine impaction and characteristics of supernumerary teeth in a South European male population.

Objective:To assess the prevalence of lateral incisor agenesis impacted canines and supernumerary teeth in a young adult male population.Materials and Methods:The panoramic radiographs of 1745 military students (mean age: 18.6 ± 0.52 years) who attended the Center of Aviation Medicine of the Armed Forces of Greece during the period 1997-2011 were initially analyzed for lateral incisor agenesis by two observers. After exclusion of the known orthodontic cases, a subgroup of 1636 examinees (mean age: 18.6 ± 0.44 years) was evaluated for canine impaction and supernumerary teeth.Results:Twenty-eight missing lateral incisors were observed in 22 military students, indicating an incidence of 1.3% in the investigated population. No lateral incisor agenesis was detected in the mandibular arch. A prevalence rate of 0.8% was determined for canine impaction in the sample of young adults. The majority of impacted teeth (86.7%) were diagnosed in the maxillary arch. Thirty-five supernumerary teeth were observed in 24 examinees (prevalence rate: 1.5%). The ratio of supernumerary teeth located in the maxilla versus the mandible was 2.2:1. The most common type of supernumerary tooth was the upper distomolar.Conclusion:The prevalence of lateral incisor agenesis, canine impaction, and supernumerary teeth ranged from 0.8 to 1.5% in the sample of male Greek military students.

Prevalence and characteristics of supernumerary teeth in east-northern Turkish population

Objectives: The aim of the present study was to determine the frequency and the distribution of supernumerary teeth (ST) in patients from east-northern Turkey. Materials and Methods: A retrospective study was performed using panoramic radiographs of 1876 patients [673 females (mean age: 13.05±2.79 years) and 1203 males (mean age: 13.63±3.18 years)] ranging in age from 7 to 34 years (mean age: 13.39±3.05 years). Demographic variables including age and sex, the type, number, eruption status of the ST were recorded. In addition, associated pathologies or complications (displacement, eruption failure, resorption of adjacent tooth, and cyst formation) caused by ST were also recorded. The Pearson chi-squared test was used to determine potential differences between genders. Results: ST were detected in 15 patients (0.75 %). The frequency of males and females with ST was 1.16 % and 0.49 %, respectively (P= 0.944). The most commonly observed ST was premolar (33.33%) followed by mesiodens (26.67%), distomolar (20.0%), lateral (13.33%), paramolar (6.67%), respectively. Most of the ST were found to be unilateral, impacted, and in the maxilla. Complications associated with ST were observed in 20.0% of the patients with ST. Conclusions: The frequency of ST in east-northern Turkish general population was found to be 0.75% with no gender difference (p>0.05). The most commonly observed ST was premolar followed by mesiodens.

Prevalence and characteristics of supernumerary teeth in a non-syndrome Turkish population: Associated pathologies and proposed treatment

The objectives of the present study were to investigate the prevalence and characteristics of supernumerary teeth and evaluate the associated pathologies and treatment protocol in a Turkish patient population. A retrospective study was performed using full-mouth periapical and panoramic radiographs of 3491 patients (2146 females and 1345 males) ranging in age from 12 to 25. For each patient with supernumerary teeth we recorded the demographic variables (including age, sex), number, location, position, type, and morphology of supernumerary teeth, associated pathologies or complications, and whether any treatment has been carried out. The Pearson chi-squared test was used to determine potential differences in the distribution of supernumerary teeth when stratified by gender. Supernumerary teeth were detected in 42 subjects (1.2%), of which 27 were males and 15 were females with a 1.8:1 male female ratio (p<0.001). The most commonly found supernumerary teeth were mesiodens (31.3%) followed by premolar (25.0%), lateral (22.9%), distomolar (14.5%), paramolar (4.2%), and canine (2.1%). Of the 48 supernumerary teeth examined, 50.0% (n=24) were conical, 81.3% (n=39) were in a vertical position, and 20.8% (n=10) were erupted. Supernumerary teeth caused rotation or displacement of the adjacent teeth in 14 cases, and the impaction of the permanent teeth in 8 cases. The prevalence of supernumerary teeth in our series was found to be 1.2%, the most frequent type being mesiodens. Rotation or displacement of permanent teeth was the most frequent complication caused by supernumerary teeth.

Supernumerary teeth in a Turkish population

Our aim in this study was to investigate the frequency, distribution, sex differences, and characteristics of supernumerary teeth in a referred Turkish population. A total of 2599 patients' panoramic radiographs (1360 girls, 1239 boys) were evaluated, including children in both the mixed and the permanent dentitions. Their mean age was 8.6 +/- 0.23 years. Number, location, classification, side, and impaction of supernumerary teeth were evaluated. Furthermore, the development of these teeth was evaluated. Eighty-four supernumerary teeth were found on 69 radiographs; 9 were deciduous and 75 were permanent teeth. Most supernumerary teeth were in the premaxillary region (67%). Mesiodens (n = 43) was the most frequent supernumerary tooth (51.2%). This was followed by the maxillary lateral incisor (15.5%), the mandibular premolar (14.3%), the maxillary canine (9.5%), the maxillary premolar (6%), the mandibular lateral incisor (2.4%), and the mandibular canine (1.2%). Sixty-two (73.8%) supernumerary teeth were impacted. The male-female ratio was 1.13:1, which was not statistically significant. The prevalence of supernumerary teeth in Turkish children was 2.7% in this study.
