Prevalence and Distribution of Nonsyndromic Dental Anomalies in Children in Eastern Saudi Arabia: A Radiographic Study

Prevalence of Dental Anomalies in Pediatric Patients at King Saud University Dental Hospital, Riyadh, Saudi Arabia-A Radiographic Analysis

OBJECTIVES

To record the prevalence of dental anomalies in children visiting King Saud Dental Hospital, Riyadh, Saudi Arabia.

MATERIALS AND METHODS

This cross-sectional study involved radiographic examination of children aged 6 to 14 years who visited King Saud Dental Hospital, Riyadh, Saudi Arabia, in the past five years. Four dental interns were trained in three consecutive sessions by a pediatric dentist and evaluated the orthopantomograms of the children. The recorded anomalies were divided into four categories: tooth number, size, position, and general. Descriptive statistics were derived and chi-square tests performed to report prevalence and significance among genders, medical histories, and dental anomalies. The significance level was set at p < 0.05.

RESULTS

Of the 1987 radiographs studied, 268 (13.48%) children had dental anomalies. The sample consisted of 51.1% female and 48.5% male children, with a mean age of 11.87 ± 2.1 years. Most study participants had mixed dentition and were healthy. The prevalence of dental anomalies reported in this study was as follows: 4.6% hypodontia, 2.7% ectopic eruption, 1.63% taurodontism, 1.2% infra-occluded molars, 1.1% impacted teeth, 0.75% root dilaceration, and 0.65% supernumerary teeth. Significant correlations were found between gender and ectopic eruption (p = 0.02) and between medical history and hypodontia (p = 0.00), ectopic eruption (p = 0.048), and root dilaceration (p = 0.03).

CONCLUSIONS

This study showed that hypodontia was the most common dental anomaly, followed by ectopic eruption and taurodontism. The findings of this study may guide dentists in better understanding, diagnosing, and treating dental anomalies in children in Riyadh, Saudi Arabia.

The prevalence of dental anomalies among Saudi Population in Makkah, Saudi Arabia

BACKGROUND

Morphological and structural abnormalities are common dental anomalies. Identifying DA and determining their prevalence can play an important role in reducing the risk of surgical intervention and improving occlusion, leading to successful dental treatments. Thus, this study aimed to determine the prevalence of DA using panoramic radiographs (OPG) in Makkah, Saudi Arabia according to gender.

MATERIALS AND METHODS

A retrospective radiographic investigation was performed, and the digital OPG of 923 patients (age range, 8-27 years) were collected. Records were collected from patients admitted at a government hospital in Makkah between January 2020 and DA in terms of tooth shape (microdontia, macrodontia, gemination, and fusion), number (supernumerary and congenitally missing teeth), and position (impaction and ectopic eruption). Several other abnormalities, such as ankyloses, dens in dents, dilacerations, and taurodontism, have also been reported. Digital radiographs from patients were systematically evaluated to diagnose each radiograph with consistent screen brightness and resolution.

RESULTS

The most prevalent DA were impaction (53.8%), hypodontia (13.6%), microdontia (8.2%), and ectopic eruption (6.7%). Taurodontism was observed more frequently in male compared to female (7.5% and 2.2%, respectively). However, there was no significant difference between gender in the distribution of other DA.

CONCLUSION

This study found that 27.8% of the Saudi population of Makkah city have DA. Clinical examination and radiographic evaluation are crucial for providing the proper treatment for patients seeking dental treatment.

Dental Anomalies in Saudi Arabia: A Systematic Review

BACKGROUND

Epidemiological studies have shown varying prevalence rates of dental anomalies worldwide, ranging from 5.2% to 56.9%, with a higher rate of 90.4% in patients with cleft lip and palate. In Saudi Arabia, studies have also reported varied prevalence rates, likely due to genetic differences or sampling variations. However, no research has yet evaluated the quality of these studies or provided an overall prevalence estimate, which is the aim of the present study. This systematic review aims to assess the prevalence and types of dental anomalies across various regions of the Kingdom of Saudi Arabia (KSA).

METHODS

A comprehensive literature search identified 10 relevant studies on different dental anomalies in Saudi Arabia. The quality of the enrolled studies was assessed using the Newcastle-Ottawa Scale (NOS), showing variability in the methodological quality of the included cohort studies, with several studies demonstrating a moderate to high risk of bias.

RESULTS

Common anomalies included hypodontia, hyperdontia, microdontia, and impacted teeth. This study highlights the varying prevalence of dental anomalies in different regions of Saudi Arabia, ranging from 2.6% to 45.1%.

CONCLUSIONS

This review highlights the need for early diagnosis and tailored treatment approaches to mitigate the clinical challenges posed by these anomalies, underscoring the importance of standardized diagnostic criteria and further research to understand regional and demographic differences in the prevalence of dental anomalies in Saudi Arabia.

Prevalence, Occurrence, and Characteristics of Supernumerary Teeth Among the Saudi Arabian Population Using Panoramic Radiographs

BACKGROUND

Supernumerary teeth numerical anomalies and the early diagnosis of supernumerary teeth is very important to avoid potential complications. The study aim was to determine the prevalence, occurrence, and characteristics of supernumerary teeth among the Arabian population.

METHODS

A retrospective radiographic study was performed using panoramic radiographs of patients attending a teaching hospital from January 2018 to December 2020. Only healthy patients with clear radiographs were included in the study, and patients with syndromes, cleft lip, and palate, and unclear radiographs were excluded from the study. The details include the patient's age and gender, supernumerary tooth number, location, orientation, and position. Only a single examiner was involved in the data collection and analysis.

RESULTS

Overall, 38 (2%) patients were observed with 47 supernumerary teeth. Among them, 76% were males and 24% were females, with a mean age of 16.1 ± 9.7 years. Mesiodens (87%) are the common type of supernumerary tooth, and the majority of the supernumerary teeth were impacted (66%). The majority of the patients presented with a single supernumerary tooth, while 24% of the patients presented with two supernumerary teeth. Sixty percent of the supernumerary teeth were conical in morphology, followed by a tuberculate morphology. In the study population, most of the supernumerary teeth were normal in orientation.

CONCLUSIONS

The prevalence of supernumerary teeth was 2%. Among them, the majority were observed at the anterior region of the maxillary arch with a conical shape of normal orientation. The gender-based comparison of location, orientation, morphology, eruption, and number of supernumerary teeth showed male predilection.

Assessment of prevalence and distribution of congenital missing teeth among patients visiting tertiary care hospital: A radiographic study

Introduction

Dental Agenesis is the usual developmental dental anomaly involving both primary and permanent dentition but most commonly it affects the permanent teeth. Genetic mutations in genes like MSX, PAX9,TGFA and AXIN2 are the likely primary contributors to tooth agenesis. Identifying the prevalence and distribution of congenital missing teeth allows for early detection and intervention which is crucial for preventing or mitigating potential dental issues that may arise due to missing teeth.

Aim & objectives

To assess the prevalence and distribution of congenitally missing teeth across different quadrants of the jaw among patients visiting to the Dental out patient department at Tertiary Care Centre of Lucknow city.

Material & method

A Questionnaire and orthopantomogram based cross-sectional study was conducted on both male and female patients aged between 15 and 30 years, coming for evaluation of their dental health problems to the hospital. Written informed consent was obtained.

Results

The overall prevalence of CMT was found to be 33.3 %. The significant difference was observed in proportion of CMT between Maxilla and Mandible sites (p = 0.008). Higher prevalence was in females compared to males for both maxillary and mandibular congenital missing teeth. (p = 0.020).

Conclusion

The most common CMT were third molars followed by lateral incisors. The insights derived from the study would aid dental professional in gaining a deeper comprehension of tooth agenesis.

Dental Anomalies in Primary Dentition among Arabian Children: A Hospital-Based Study

An observational study was carried out in a teaching hospital in Saudi Arabia to determine the occurrence of dental anomalies among Arabian children. The study included children of Saudi nationality with primary teeth. The study assessed the prevalence of dental anomalies in their primary dentition. The assessment and data collection were conducted by a single examiner, utilizing clinical examination and intra-oral radiographs. A comparative analysis was conducted to examine dental anomalies in relation to gender (boys and girls) and arch type (maxillary and mandibular). In addition, the study explored the occurrence of gender-specific dental anomalies depending on arch type. The data analysis was conducted using IBM Statistics (version 21.0) with a significance level of p < 0.05. In total, there were 245 children included in the final analysis. The study population consisted of boys (66%) and girls (34%), with an average age of 4.87 ± 0.9 years. Taurodontism was the most prevalent dental abnormality, occurring in 2.8% of the individuals in the study sample. The study sample exhibited hypodontia in 2%, supernumerary teeth in 2.4%, double teeth in 2%, and microdontia in 1.2%. Talon cusp and macrodontia have a relatively low incidence of 0.4%. Boys exhibit supernumerary teeth, microdontia, macrodontia, talon cusp, and taurodontism, whereas hypodontia and double teeth were more frequent in girls.

Assessment of the condylar response of two differently anchored fixed functional appliances in class II malocclusion in young adult orthodontic patients: A randomized clinical trial

OBJECTIVE

Measuring the condylar volume changes after treatment with skeletally anchored type IV Herbst appliance vs. Twin Force Bite Corrector (TFBC) in class II malocclusion in young adult patients.

MATERIALS AND METHODS

Twenty class II malocclusion participants were randomly involved in our randomized clinical study. They are divided equally into two groups: group I (10 patients with an age range of 16 to 18 years and a mean age of (17.15 ± 0.62) (five males and five females) with a mean Angle formed between (A) point and (Nasion) point and (B) point, to determine anteroposterior relation between maxilla and mandible (ANB) of 6.20 (1.03) and a mean mandibular length of 106.1 (1.7), who were treated by a skeletally anchored type IV Herbst appliance, supported at the mandible by two mini-plates fixed bilaterally at the mandibular symphysis; group II (10 patients with an age range of 15 to 18 years and a mean age of (16.85 ± 0.33) (six males and four females) with a mean ANB of 6.80 (0.89) and a mean mandibular length of 107.3 (2.36), who were treated by a TFBC that was installed just mesial to the tube of the maxillary first permanent molar and distal to the bracket of the lower canine for 4 months. According to the Index of Orthognathic Functional Treatment Need (IOFTN) index, the participants in both groups have grade 4 (great need for treatment) as they have excessive overjet (6-9 mm). Cone-beam computed tomography (CBCT) was taken just before installing fixed functional appliances and after the removal. The condylar volume was measured using Dolphin software. Parametric measurements were performed by the independent t-test, while non-parametric variables (percent change) were compared by the Mann-Whitney U-test.

RESULTS

On the right side, the Herbst group recorded a percent increase (median = 1.23%), while TFBC recorded a median percent decrease (-7.85%). This change is statistically significant (P = 0.008).

CONCLUSIONS

The difference in the condylar volume was significantly higher with the mini-plate anchored Herbst appliance than with the dentally anchored TFBC group.

Odontoma and other congenital dental anomalies: Implications for forensic identification

Forensic odontology plays a crucial role in establishing the identity in mass disasters and criminal cases with high accuracy. Dental anomalies and features help in such situations. Congenital and developmental dental anomalies can be easily documented to establish distinctive and individualistic characteristics of an individual. The location, number of teeth involved, and the type of anomaly vary between individuals. Similarly, dental malformations also assist greatly in the identification process. Many types of dental anomalies have been studied in the past for their individualistic characteristics in forensic examinations. One such dental anomaly is odontoma, which is a benign odontogenic malformation. This malformation may also help in the identification of the deceased, when recorded and examined accurately. An odontome is a malformed teeth-like structures consisting of enamel, dentin, and pulpal tissue, formed due to the growth of completely differentiated epithelial and mesenchymal cells. If antemortem (AM) dental records incorporate information regarding odontomes and other dental anomalies, including in radiographs, orthopantomograms or microradiographs, positive identification may be established by comparison of these records with postmortem (PM) records. In the present communication, a rare case of compound composite odontoma in the anterior mandible with multiple denticles has been discussed with a brief overview of congenital and developmental dental anomalies. The authors emphasize the importance of such rare dental anomalies and malformations which may be used for identifying the deceased in mass disasters and forensic identification.
