Objective. The aim of this cross-sectional study was to investigate the prevalence of dental anomalies that could be a cause of malocclusion in the western region of Saudi Arabia. Materials and Methods. A retrospective study of 878 digital orthopantomograms (OPGs) taken of patients, age ranging between 12 and 30 years, who presented to treatment at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia between 2002 and 2011. The OPGs and dental records were reviewed for congenitally missing teeth, supernumerary teeth, impactions, ectopic eruption, transposition, germination, fusion, dilacerations, taurodontism, dens in dent, and any other unusual conditions that can be assessed with OPG. Results. The prevalence of patient that exhibited at least one dental anomaly was 396 (45.1%) patients. The prevalence of congenitally missing teeth was 226 (25.7%), impacted teeth 186 (21.1%), dilacerated teeth 10 (1.1%), supernumerary teeth 3 (0.3%), odontoma 1 (0.1%), and taurodontism was also 1 case (0.1%) of the total radiographs reviewed. Conclusions. Congenitally missing teeth were found to be the most prevalent anomaly (25.7%), and the second frequent anomaly was impacted teeth (21.1%), whereas root dilacerations, supernumerary teeth, and taurodontism were the least frequent anomalies (1.1%, 0.3% and 0.1%, resp.).

ABSTRACT Congenitally missing teeth are one of the most common dental anomalies which may be termed as dental agenesis. Polygenesis, the formation of one or more supernumerary teeth, occurs much less frequently than agenesis. Hypodontia and hyperdontia are regarded as the opposite dental developmental anomalies. However, their simultaneous presence in the same individual is a rare condition. A case of concomitant hypo-hyperdontia (CHH) is presented here, wherein a 20-year-old female has missing mandibular central incisors, maxillary second molars, and all the third molars. In addition, she has a malformed supernumerary tooth in the mandibular left anterior region. Documentation of such rare case reports is necessary as it helps in minimizing the clinicians' challenge in diagnosing such cases and thus helpful in providing a multidisciplinary approach in treating such 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.

The incidence of dental abnormalities in the cleft lip and palate population has been reported to be much higher than in the normal population. The role of genes in the production of a cleft lip and palate, and dental anomalies is thought to be complex, with autosomal dominant, recessive, and x-linked genes all playing a role. Noncleft parents can carry some of the cleft lip and palate genes, which produce clinically subtle manifestations in their facial skeleton. The purpose of this study was to look for evidence of increased dental anomalies in the non-cleft parents of cleft lip and palate children. The dentitions of the parents of 60 children with different types of cleft lip and palate were examined prospectively to see whether or not they exhibited features found more readily in the cleft lip and palate rather than did the normal population. Their dentitions were studied to record the following dental features: congenitally missing teeth, supernumerary teeth, or morphologic changes of the crowns of the permanent teeth. The number and position of any frenal attachments were also recorded. The results of this study did not show any differences in incidence of dental anomalies from the noncleft population. There was no evidence to support the hypothesis that congenital absence of lateral incisors is a microform of cleft lip and palate. Further, these results also failed to reveal any consistent pattern in the number and position of frenal attachments.

Background: Dental agenesis is a term that refers to the absence of one or more teeth, and hypodontia refers to a severe type of tooth agenesis involving less than six or more than one congenitally missing teeth, excluding the third molars. Purpose: This aimed to report the correction of overbite by using intrusion archwires. Case: A 20-year-old female patient had class I malocclusion and deep overbite, incisor retroclination, mild mandibular crowding and agenesis of 12, 13, 14, 15, and 24. Case management: The case was treated with non-extraction using 0.022 pre-adjusted technique to level and unravel using intrusion archwires to correct the deep overbite. Conclusion: The 17-month treatment resulted in a corrected overbite, good occlusion, and good facial aesthetics.
