ABSTRACT Objectives: The aim of this study was to investigate the prevalence and distribution of hypodontia in the permanent teeth among a group of the Qatari sample and to compare the present results with findings from other populations. Materials and Methods: Records of 1269 Qatari patients (674 females; mean age 11.8 ± 2.3 and 595 males; mean age 11.4 ± 2.2) which included panoramic radiographs were examined to identify hypodontia. All permanent teeth were investigated except third molars. Results: The prevalence of hypodontia was 6.2% (females 8% and males 4.2%; P < 0.05). The majority of patients had one or two missing teeth. There were no significant differences between right and left sides for any particular tooth. The most frequently missing teeth were maxillary lateral incisors (36.2%), followed by mandibular second premolar (32.6%) and maxillary second premolar (20.2%). Hypodontia was more commonly found unilaterally than bilaterally (63.2% and 44.3%; respectively). Conclusions: The prevalence of hypodontia in a group of the Qatari population was within the average value of the majority of published studies in the literature. Hypodontia was significantly more prevalent in females. Although less prevalent, considerable cases of bilateral missing were found in the present study, which necessitates the urgent need for intervention and multi-disciplinary team approach for management.

ABSTRACT Objective: The aim of this retrospective study was to assess the prevalence and distribution of hypodontia in the permanent dentition in a sample of Turkish patients who referred to the Ankara Dental Hospital for orthodontic treatment. Materials and Methods: The pre-treatment orthodontic records of 2530 patients, 1382 girls (54.62%) and 1148 boys (45.38%) between the chronological ages of 7 and 16 years, were examined for evidence of hypodontia. The third molars were excluded in this study. Results: The prevalence of hypodontia in the inspected population was 5% (3.05% for girls, 1.95% for boys). The average number of the congenitally missing teeth per patient was 2.03 (1.08 for girls, 0.95 for boys). The prevalence of the congenitally missing permanent teeth was 34% for the upper laterals, 30% for the lower second premolars, 12.5% for the upper second premolars and 23.5% for the other teeth. Most patients with hypodontia (84.9%) (57.13% for girls, 27.77% for boys) had got missing either one tooth (45.23%) or two teeth (39.67%). Conclusions: The prevalence of hypodontia in girls was higher than in boys in this sample of the Turkish patients. The upper laterals and lower second premolars were consecutively the most symmetrically absent teeth. The prevalence of advanced hypodontia was lower than single and symmetrical hypodontia.

ABSTRACT Hypodontia is the term used to describe the developmental absence of one or more primary or permanent teeth, excluding the third molars. It is the most commonly occurring developmental dental anomaly and can be a challenge to manage clinically. Hypodontia can occur in association with syndrome or it may occur in nonsyndromic patient. Bilateral occurrence is common but it is very rare to see two bilateral congenital missing teeth in a nonsyndromic patient. This case report presents a rare occurrence of congenital bilateral missing mandibular second premolars and mandibular lateral incisors in a nonsyndromic patient.

ABSTRACT Objective: The aim was to evaluate the prevalence and distribution of tooth number anomalies in a Turkish subpopulation. Materials and Methods: A population of 2722 patients (1532 females and 1190 males; mean age, 12.33 ± 2.5 years) was retrospectively examined to determine the prevalence and distribution of the hypodontia, oligodontia, and hyperdontia using panoramic radiographs. All permanent teeth were investigated except thirds molars and the data obtained were recorded as unilateral (left or right) or bilateral according to gender. Pearson's Chi-squared and Fisher exact tests were used for difference comparisons (P < 0.05). Results: Permanent tooth anomalies were found in at least 132 (4.84%) of 2722 patients with no statistically difference between the genders, consists of 4.63% females and 5.12% males. Distribution of hyperdontia was statistically significant difference between genders, whereas distribution of hypodontia and oligodontia was no significant difference between genders. Hypodontia was the most frequently observed anomaly (3.67%), followed by hyperdontia (0.96%), and oligodontia (0.21%). Oligodontia and hypodontia were more frequent in females (3.98% and 0.26%, respectively), whereas hyperdontia was more frequently observed in males (1.68%). Maxillary lateral incisors were most common missing teeth (2.27%), while the frequency of hyperdontia was most common in premolars. Conclusion: The prevalence of teeth number anomalies was 4.84% of dental patients. Maxillary lateral incisors were most common missing teeth, while the frequency of hyperdontia was most common in premolars.

Missing Tooth

Purpose: The aim of this study was to summarize the literature on the most frequently missing permanent teeth excluding the third molars. Study design: A search was conducted to find all the available literature (in various scientific and general databases) regarding the most commonly missing teeth with respect to ethnicity and time, as well as factors biasing this outcome. Quality assessment was done to exclude studies with inconsistent information, poor designs, or data pertaining to syndromic cases or the third molars. The role of biasing factors was as well quantitatively assessed using statistical analyses [Q-test, Egger regression, Spearman correlation coefficient, multiple linear regression, Welch t-test] (α=0.05). Results: A total of 81 reports was included. The meta-sample was heterogeneous (P=0.000, Q-test). No significant publication bias was detected (P&gt;0.1, Egger regression). The mandibular second premolar was reported as the most commonly missing tooth in most studies, followed by the maxillary lateral (the most commonly missing in the rest). In terms of the missing share of each tooth percent of all missing teeth, the mandibular second premolar and incisors are more likely to be absent, followed by the maxillary second premolar and lateral. The absence of different teeth can be affected by the ethnicity, sample types (epidemiological or dental patients), sample sizes (only in the case of bimaxillary second premolars), and the minimum ages of pooled subjects (only in the case of the maxillary lateral and the mandibular second premolar). Conclusions: Since enrolling younger patients can bias the results, older patients should be sampled.

ABSTRACT Objective: There is no data specific to the Qatari population on the prevalence and distribution of hyperdontia. The aim of this study was to investigate the prevalence and distribution of hyperdontia in the permanent teeth among a group of Qatari sample and to compare the present results with findings from other populations. Materials and Methods: Records of 1269 Qatari patients (674 females; mean age 11.8 ± 2.3 and 595 males; mean age 11.4 ± 2.2 years) which included panoramic radiographs were examined to identify hyperdontia in the permanent dentition. Supernumerary teeth were assessed for their location, morphology, number, and whether impacted or not. Results: The prevalence of hyperdontia was 1.6% (females 0.7% and males 0.9%; P < 0169). The most common type of supernumerary teeth was the supplemental (45.5%), followed by the conical (40%). Of the supplemental teeth, the mandibular incisor was the most prevalent (60%), followed by the premolar (20%). No significant difference in the prevalence was found between the maxilla and mandible. More than half of supernumerary teeth identified were impacted (54.5%). Conclusions: The prevalence of hyperdontia in a group of Qatari population was within the normal range of the majority of published studies in the literature. Although not significant, hyperdontia cases were more prevalent in male patients.

Objective: The purpose of this study was to investigate the prevalence of peg-shaped maxillary lateral incisors and the incidence of associated dental anomalies in children. Study design: We investigated the prevalence of peg-laterals and incidence of associated dental anomalies in 3,834 children aged 7–15 who visited the Department of Pediatric Dentistry from January 2010 to December 2015 and underwent panoramic radiographs. Results: The prevalence of peg-laterals was 1.69% in boys, 1.75% in girls, and 1.72% overall. Among children with peg-laterals, the frequencies of associated dental anomalies were as follows: congenitally missing teeth, 31.8%; dens invaginatus, 19.7%; palatally displaced canines, 12.1%; supernumerary teeth, 7.6%; and transposition, 7.6%. Conclusion: As children with peg-laterals have a higher incidence of other dental anomalies, careful consideration is needed when planning diagnosis and treatment.

Objective. To quantify the severity of malocclusion and dental esthetic problems in untreated Down syndrome (DS) and untreated non-Down syndrome children age 8–14 years old using the PAR and ICON Indices.Materials and Methods. This retrospective study evaluated pretreatment study models, intraoral photographs, and panoramic radiographs of 30 Down syndrome and two groups of 30 non-Down syndrome patients (private practice and university clinic) age 8–14 years. The models were scored via PAR and ICON Indices, and descriptive characteristics such as Angle classification, missing or impacted teeth, crossbites, open bites, and other dental anomalies were recorded.Results. The DS group had significantly greater PAR and ICON scores, as well as 10 times more missing teeth than the non-DS group. The DS group possessed predominantly Class III malocclusions, with the presence of both anterior and posterior crossbites in a majority of the patients. The non-DS group had mostly Class I or II malocclusion with markedly fewer missing teeth and crossbites. The DS group also had more severe malocclusions based upon occlusal traits such as open bite and type of malocclusion.Conclusion. The DS group had very severe malocclusions, while the control group from the university clinic had more severe malocclusions than a control group from a private practice.

Abstract Background: Third molars are the last to erupt in the permanent teeth series. These teeth are the most likely to be impacted this research aims to evaluate whether the distance between mandibular retromolar foramen and mandibular angle renders different results in case of absence or presence of lower third molar in both genders.Methods: A respective study conducted on 186 the distance between mandibular retromolar foramen and mandibular angle were examined on Digital panoramic radiograph (DPR). The radiographs were grouped according to Absence or presence of left lower third molar and subject gender. A logistic regression model was created using the statistically significant data.Results: The lower third molar impaction on the distance between mandibular retromolar foramen and mandibular angle was not significantly different between mean groups (absence and presence) when gender is disregard. The distance between the two was significantly increased in the male subgroup.Conclusion: The relation between the distance between mandibular retromolar foramen and mandibular angle and third molar using panoramic radiographs showed no fundamental difference in the distance between mandibular retromolar foramen and mandibular angle in case of absence or presence of lower third molar when gender is disregard.

ABSTRACT Objective: This study aims to investigate the demographics, patient health status, position of the teeth, pericoronitis incidence, surgical complications, use of antibiotics to third molar removal and correlate those findings. Methods: Based on panoramic radiographs, the teeth were classified as proposed by Pell and Gregory and Winter. The binomial test for proportions with a significance level of 5% was applied. Results: Records of 337 patients submitted 1178 third molar extractions in the period from 1993 to 2011 were reviewed. Most upper teeth were vertically positioned, (84.2%) (p<0.0001), class I (49.55%) (p<0.0001), position C (58.88%) (p<0.0001) and most inferiors were mesioangulated (42.03%) (p<0.0122), class II (60.22%) (p<0.0001), position A (48.15%) (p<0.0001). Complications occurred in 2.88% of the procedures (p<0.0006), mainly in women (69.7%) (p<0.0014) and more frequently in patients who did not receive antibiotics (71.43%) (p<0.0027). Complications were more frequent after extraction of inferior third molars (75.75%) (p<0.0001). The most common complication was alveolitis (52.51%) (p<0.0006). Conclusion: In this study, the complication rates were low. They were more frequent in women who did not receive antibiotics. The most common complication was alveolitis.
