Prevalence and patterns of tooth agenesis among Malay children

Mani SA, Mohsin WS, John J

Southeast Asian J. Trop. Med. Public Health, 2014 Mar;45(2):490-8.

PMID: 24968691

Tooth agenesis in Malay children, hitherto unreported, was assessed retrospectively from orthopantomograms of 834 healthy children aged 12-16 years who attended the Dental Clinic of Universiti Sains Malaysia. All teeth, including third molars, were assessed for agenesis. On an average, 2.3 teeth were missing per child. Missing third molars were found in 25.7% of children with one or two third molars found to be missing in 18.3% of children. Three point two percent of children had missing teeth other than third molars. After third molars, the upper lateral incisors were found to be the most common missing tooth (1.7%), followed by upper and lower second premolars (1.5%). Eight missing upper canines were also seen (1%). Bilateral agenesis was more common than unilateral agenesis. There were no significant differences between males and females. There was a significant difference between missing teeth between the maxilla and the mandible and right and left side, with more missing teeth in the maxilla and on the right side. The odds of any 3rd molar missing were increased 3.3 times when there was any other missing tooth. In conclusion, the prevalence of tooth agenesis among the studied population was within the normal range, but less than some Asian countries. Unlike other Asian countries, the upper lateral incisor was the most common missing tooth. The prevalence of maxillary canine agenesis was higher than most previous reports. Missing teeth were associated with missing third molars, which is likely due to a genetic abnormality.

BMJ Case Rep, 2017 Aug 10;2017.

PMID: 28798243 DOI: 10.1136/bcr-2017-220683

Numerical anomalies, either addition or deletion, are quite a common findings in human dentition. However, it is extremely rare to find both hypodontia and hyperdontia simultaneously in the same individual. This condition is referred as concomitant hypohyperdontia (CHH). Aetiology of this condition is still obscure. The prevalence of CHH has been reported to be between 0.002% and 3.1%. This case report highlights a rare occurrence of bimaxillary CHH represented by the absence of both mandibular central incisors and presence of two supernumerary teeth in the maxillary anterior segment. The rarity of such condition of mixed hypodontia as well as hyperdontia in single human dentition prompted the author to report the case.

Introduction: The objective of this study was to determine the prevalence and the pattern of hypodontia among orthodontic patients in Klinik Pergigian Jalan Sultan Mahmud, Kuala Terengganu.
Materials and Methods: A retrospective of 351 orthodontic patients record review study was conducted; comprised of 104 males and 247 females. The records were reviewed by trained dental officer between October 2016 and June 2017. The Chi-square and Fisher's Exact Tests were carried out for statistical analysis.
Results: The prevalence of hypodontia was 10.8%. Thirty-eight patients were found to have at least single missing tooth. A significant difference was found between males and females of having hypodontia (p = 0.048). No significant difference was found for hypodontia patients by races (p = 0.829). The maxillary lateral incisor was the most frequently missing tooth followed by mandibular second premolars and mandibular lateral incisors. Hypodontia cases observed tended to be more likely occurred in the upper left arch compared to the lower arch. The majority of hypodontia patients had single missing tooth, but rarely more than 3 missing teeth. Hypodontia patients had mainly Class III malocclusion, however no statistically significant was found (p= 0.081).
Conclusion(s): The prevalence of hypodontia of this study was within the range of what is being reported in the literature and showed gender significant. Hypodontia was mainly involved maxillary lateral incisors; more prevalent in the upper arch; and mostly observed in patients with Class III malocclusion in the study sample. Early detection and accurate diagnosis are essential. Therefore, alternative treatment modalities can be well planned under multidisciplinary team approach in restoring the aesthetic and function.

Hypodontia in the permanent dentition: a study of its prevalence in Malaysian children

Nik-Hussein NN

Aust Orthod J, 1989 Oct;11(2):93-5.

PMID: 2639661

An investigation of the prevalence and distribution of hypodontia was carried out in Malaysian children between the ages of five to fifteen years. Hypodontia occurred in 2.8 per cent of these children. A greater number of females were found to have hypodontia, the ratio of affected females to males is 1.6:1. The teeth most frequently missing were the maxillary lateral incisors followed by the mandibular lateral incisors, then the mandibular second premolars. The aetiology of the condition is discussed. It is noteworthy that studies showing the lower second premolars to be most commonly missing have younger subjects. This suggests delayed development of these teeth in some individuals.

PMID: 36554823 DOI: 10.3390/ijerph192416944

Oral Impacts on Daily Performances (OIDP) can be used as a generic or condition-specific oral health-related quality of life (OHRQoL) instrument. It offers different contexts on how dental conditions affect OHRQoL. This cross-sectional study aimed to validate a newly translated Malay OIDP (OIDP-M), compare OHRQoL, decayed, missing, or filled teeth (DMFT) in Malaysians, and investigate factors associated with OHRQoL. A total of 368 Malaysians were surveyed and examined for DMFT. Short-form oral health impact profile-Malaysia [S-OHIP(M)] and OIDP-M were used to measure OHRQoL. The OIDP-M was tested for reliability and validity. DMFT, S-OHIP(M), and OIDP-M between ethnicities were compared. Associations between ethnicity, DMFT, S-OHIP(M), and OIDP-M of Malays and Chinese were evaluated through partial correlation. Malays and Chinese had more filled teeth and DMFT compared with Indians. Malays reported worse OHRQoL through S-OHIP(M). Decayed teeth were positively associated with S-OHIP(M), physical, psychological, social disabilities, and handicap. For OIDP-M, decayed teeth were positively associated with OIDP-M, working, and sleeping. Missing teeth and ethnicity were positively associated with eating and speaking. Filled teeth were negatively associated with cleaning teeth. The OIDP-M was reliable and valid for evaluating OHRQoL. There were differences in DMFT and OHRQoL between ethnicities. Ethnicity affects OHRQoL, where Malays experienced worse OHRQoL due to dental problems.

Fulltext Missing Tooth: A New Technique to Maintain the Space for Prosthetic Replacement During Orthodontic Treatment - A Report of Two Cases

Radzi, Z., Yahya, N.A., Zamzam, N., Spencer, R.J.

Ann Dent, 2004;11(1):-.

MyJurnal

Missing teeth can be due to hypodontia, trauma or extraction. In general, the options for treatment depend on the severity of the hypodontia and the severity of the malocclusion. Occasionally, the space from missing teeth has to be maintained for prosthetic replacement and require an orthodontic/restorative approach. It is very important to ensure the space maintained is adequate for aesthetic reason so that it can be replaced with a prosthesis after the orthodontic treatment is completed. This article discusses a new innovation and clinical technique for maintaining this space during orthodontic treatment by using an acrylic tooth with several modifications. This innovation will be illustrated using two cases.

Oligodontia, although rare, may have significant impact on the quality of life of those affected with it. Provision of restorative treatment for these patients can be very challenging and demanding for clinicians, especially during the active growth phase. Nevertheless, the dental needs of these patients are real and should be addressed appropriately. The present case report described a restorative rehabilitative plan and execution of different restorative treatment modalities in a 14-year-old patient with oligodontia. The challenges faced in the provision of dental care were highlighted. The treatment outcome showed a positive psychological impact on the well-being of the patient based on parental observations.

MyJurnal

Since the establishment of implant in dentistry, the use of removable partial denture in replacing missing teeth apparently becomes less popular. The situation is made worse by the renowned limitations of removable partial denture. One of the obvious limitations of removable partial denture, especially in replacing missing anterior teeth is the unsightly view of metal used for retentive clasp. This case report describes the use of spring loaded plunger attachments as an alternative way to achieve retention and at the same time improving the aesthetic of the prosthesis.

PAX9 (Paired box 9) gene is one of the genes which play significant role during
craniofacial development. Single nucleotide polymorphism (SNP) in PAX9 has been associated with
Class II/Division 2 malocclusion (with or without hypodontia). However, the relationship between
PAX9 SNP marker (rs8004560) with mandibular prognathism (MP) has not been analysed, at least in
our local population. This study aimed to detect the presence of PAX9 (rs8004560) SNP in Class III
malocclusion patients (with MP) in the local population. (Copied from article).

PMID: 9161200

The study consisted of analysis of all cases of anomalies in the primary dentition that were seen or treated by the authors in the Department of Children's Dentistry and Orthodontics. A total of 79 occurrences of anomalies was seen in 65 children. The anomalies detected were double teeth, hypodontia and supernumerary teeth. Radiographic examinations of the affected children showed that over 60% of the cases with anomalies in the primary dentition are associated with anomalies of the succadeneous permanent dentition. All subjects with hypodontia of the primary dentition presented with hypodontia of the permanent dentition. However, anomalies of the permanent dentition were seen in 59% of subjects with primary double tooth and 50% of subjects with primary supernumerary tooth.

The aim of this study was to investigate the prevalence of third molar agenesis and other associated dental anomalies in Bangladeshi population and to investigate the relationship of other dental anomalies with the third molar presence/agenesis. A retrospective study was performed using panoramic radiographs of 5923 patients, who ranged in age from 10 to 50 years. All radiographs were analyzed by Planmeca Romexis® 3.0 software (Planmeca Oy, Helsinki, Finland). Pearson chi-square and one way ANOVA (Post Hoc) test were conducted. The prevalence of third molar agenesis was 38.4%. The frequency of third molar agenesis was significantly higher in females than males (p <0.025). Third molar agenesis was significantly more prevalent in maxilla as compared to mandible (p <0.007). The prevalence of other dental anomalies was 6.5%, among them hypodontia was 3.1%. Prevalence of third molar agenesis varies in different geographic region. Among the other dental anomalies hypodontia was more prevalent.
