High Frequency Of Dental Anomalies Research Articles

TO DETERMINE DENTAL DEFECTS & PERIODONTAL STATUS OF PATIENTS WITH CLEFT LIP & CLEFT PALATE – A CROSS-SECTIONAL STUDY

Introduction: The aim of this study will be to assess the prevalence of dental defects and periodontal status in Cleft patients up to 18 years old children in Rajasthan. Materials and methods: The sample consisted of hundred cleft patients in the study group and hundred patients in the control group of under 18 years of age. Clinical examination was performed on all the patients to detect dental defect using m-DDE index. Student's t-test was used to compare the means between cleft group and the control group. The Chi-square test was employed to determine statistical differences in frequencies between the two groups and also, we have evaluated the prevalence rate of dental defects according to their age criteria. Results: Poor oral hygiene and periodontal status was observed in cleft patients, respectively. In all tested dental defects, a higher frequency of dental anomalies was noted in the cleft patients as compared with the controls. There was also some signicant difference in dental anomalies according to their age variations. Conclusion: This study shows that cleft children have higher prevalence of dental anomalies than normal children. It's essential that the patient with a cleft is monitored closely with regular follow up. Education about oral health must be given repeatedly

Association between Dental Anomalies and Orofacial Clefts: A Meta-analysis.

To conduct a systematic review and meta-analysis to assess whether individuals with nonsyndromic orofacial clefts (OCs) display a higher frequency of dental anomalies (DAs) when compared with individuals without OCs. A literature search of indexed databases (PubMed, Cochrane, Web of Science, Embase, Scopus, and LILACS) was conducted without language restriction up to and including February 1, 2020. Cross-referencing was used to further identify articles. Several cleft teams across the United States and Europe were contacted to obtain unpublished data. The eligibility criteria were observational studies with original data that statistically compared individuals with OC without syndromes and those without OC on any type of DA in primary and/or permanent dentition. Random effects meta-analysis through the Mantel-Haenszel estimator was used to evaluate the association between OC and DA based on odds ratios (ORs) with 95% confidence intervals (CIs). The literature search generated 933 records, and 75 full-text articles were reviewed. Twenty-six studies encompassing 15,213 individuals met the inclusion criteria. The meta-analysis revealed statistically significant associations between OC and agenesis (OR, 14.2; 95% CI, 9.4 to 21.3), supernumerary teeth (OR, 5.7; 95% CI, 3.3 to 9.7), developmental enamel defects (OR, 5.6; 95% CI, 3.5 to 9.0), microdontia (OR, 14.8; 95% CI, 4.0 to 54.6), peg-shaped anterior teeth (OR, 12.2; 95% CI, 3.6 to 41.2), taurodontism (OR, 1.7; 95% CI, 1.0 to 2.7), tooth malposition and/or transposition (OR, 5.6; 95% CI, 2.8 to 11.5), tooth rotation (OR, 3.2; 95% CI, 1.3 to 8.2), and tooth impaction (OR, 3.6; 95% CI, 1.1 to 12.2). The OR estimates of the reviewed studies exhibited significant heterogeneity (P < 0.0001). No association was observed between OC and fusion and/or gemination. Within the limitations of this study, the available evidence suggests that individuals with OCs are more likely to present with a range of DAs than their unaffected peers. The findings of the current review suggest that individuals with orofacial clefts (OCs) are more likely to present with a range of dental anomalies than their unaffected peers. Understanding the association between OCs and dental anomalies is essential in guiding clinicians during treatment-planning procedures and is important in raising our awareness of the possible need for future dental treatment for patients with OCs.

Patterns of dental anomalies in patients with nonsyndromic oral cleft

Aim: To characterize the patterns of dental anomalies (DA) in the mixed and permanent dentitions of patients with nonsyndromic oral cleft (NSOC). Methods: This cross-sectional, observational, case-control study included 173 patients, 61 with mixed dentition (NSOC=29 and control=32) and 112 with permanent dentition (NSOC=57 and control=55). All subjected were submitted to clinical and radiographic examination. Dental anomalies of eruption, number, size and shape outside the cleft area were considered. Results: Although there was no statistical significance among patients with mixed dentition, dental agenesis was the anomaly more common in this group. In patients with permanent dentition, a higher prevalence of DA in NSOC group compared to control group was observed (p=0.02). Gyroversion and dental agenesis were the DA more frequently observed in the permanent dentition and the second premolar was the tooth more affected (p=0.003). Mandible and the left side were more involved, and dental agenesis was more frequently found in patients with unilateral cleft lip with or without cleft palate (NSCL±P). Conclusion: Our findings show a higher frequency of DA in NSOCs than in the control group in patients with permanent dentition, mainly due to a higher occurrence of agenesis of second premolars in patients with unilateral NSCL±P.

Dental anomalies in orthodontic patients with and without skeletal discrepancies

Objective:To determine whether individuals withskeletal discrepancies of Class II or IIIdisplay a higher frequency of dental anomalies in comparison with individuals with Class I malocclusion. Design:A systematic search of the main electronic medical scientific literaturedatabases was conducted. Observational studies were selected if mentioning dental anomalies in the different skeletal malocclusion patterns.Results:A total of 4,768 studies were found and the duplicated studies (1,279) were removed, resulting in 3,489 papers to be analyzed. After screening by title, 138 were fit for screening by abstract. After that, a total of 13 papers were carefully read in full. Five studies included dental anomaly frequencies in orthodontic patients and included 7,679 participants. The frequency of dental anomalies ranged from 11.2% to 40.3%.It was observed that individuals with skeletal discrepancies of Class II and III had more dental anomalies when compared to individuals with Class I.Conclusion:Individuals with skeletal malocclusion patternshave more dental anomalies and there is an association between dental anomalies and skeletal Class II or Class III malocclusion patterns.

Dental anomalies in the deciduous dentition of non-syndromic oral clefts patients

Abstract Objectives: to investigate the prevalence of dental anomalies in complete deciduous dentition of children with NSCL/P. Methods: this study included 75 children with NSCL/P and 286 healthy control. In both groups the children had deciduous dentition with ages varying from 4 to 6 years. Clinical examination, panoramic and periapical radiographies were performed and dental anomalies of number and shape were considered. Results: there was a higher prevalence of dental anomalies in the case group, compared to the control group. In all, 42 dental anomalies were identified, 25.33% in the case group and 8.04% in control group (p&lt;0.001). Therewas a higher frequency of dental anomalies in NSCL/P (47.36%), followed by non-syndromic cleft lip (31.57%) and non-syndromic cleft palate (21.05%). The occurrence of agenesis (p= 0.005) and twinning (p = 0.029) were higher in the case group. Conclusions: the occurrence of agenesis and dental twinning was more frequent in the case group and may contribute to the definition of oral cleft subphenotype.

Prevalence and distribution of dental anomalies among a sample of orthodontic and non-orthodontic patients: A retrospective study

Aims and Objectives: Dental anomalies are clinically evident abnormalities, which can lead to functional, aesthetic, and occlusal problems, which may complicate orthodontic treatment planning. The purpose of the study was to address the prevalence and distribution of dental anomalies in a group of Yemeni dental patients and to compare the presence of dental anomalies in patients seeking dental and orthodontic treatment. Materials and Methods: This retrospective study was conducted on 1675 digital panoramic radiographs for dental patients aged between 9 and 52 years, who visited orthodontic specialty centers in Sana’a, Yemen, from January 2018 to February 2019. The digital panoramic radiographs were evaluated for the prevalence and distribution of dental anomalies, such as supernumerary, hypodontia, microdontia, macrodontia, taurodontism, dens evaginatus, dens invaginatus, impaction, and dilacerations. Results: The distribution of anomalies was 30.61% among the orthodontic patients and 22.96% through non-orthodontic patients. The most frequent anomaly among the subjects was impaction (14%–47%), macrodontia (11.8%), microdontia (9.23%), hypodontia (7.48%), dilaceration (5.07%), dens evaginatus (1.91%), dens invaginatus (1.58%), hyperdontia (0.99%), and taurodontism (0.91%). Among the individuals who had dental anomalies, 57.9% of subjects showed one type of anomaly, 30.5% had two types of anomalies, whereas 11,49% had more than two types of anomalies. The selected dental anomalies in this study showed high prevalence rate among the orthodontic patients. Conclusion: Variations in data and results among different studies suggest the impact of racial, genetic, and environmental factors. The high frequency of dental anomalies emphasizes the need of early detection and diagnosis, which can be achieved through radiographic imaging, this would avoid potential orthodontic, functional, and aesthetic problems, and further emphasizes awareness to minimize any means of complexity of orthodontic and other dental problems.

Prevalence of Dental Developmental Anomalies in Patients Attending a Faculty of Dentistry in Ajman, United Arab Emirates

Objective: To determine the prevalence of dental developmental anomalies among patients visiting the dental clinics at Ajman University, United Arab Emirates. Material and Methods: This retrospective study consisted of 425 digital panoramic radiographs. The study sample included people in the United Arab Emirates who have visited the outpatient dental clinics at the Faculty of Dentistry, at Ajman University. These OPGs have been evaluated for the presence of dental anomalies such as: Macrodontia, Microdontia, Talon cusp, Taurodontism, Dilaceration, Ectopic Eruption, Supernumerary teeth or roots, Fusion, Gemination, and Concrescense. Results: 80.7% had at least 1 anomaly, with the maximum of 5 anomalies presented in 1.2% of the sample. Dilacerations were the most commonly identified anomaly (61.4%), followed by missing third molars (22.8%), and Ectopic Eruption (15.5%) where (12.9%) of this anomaly has affected the maxillary canines. Hypercementosis (10.2%) followed by Microdontia (4.6%), which was mostly seen in the Upper laterals. Taurodontism accounted for (4.1%), Macrodontia (2.3%) and Talon cusp (2.3%). Gemination, Dens Invaginatus, and Concrescence were separately present in 1.1%, each one, of the cases observed. Conclusion: Variations in data and results among different studies suggest the impact of racial, genetic and environmental factors. The high frequency of dental anomalies emphasize the need of early detection and diagnosis which can be achieved through radiographic imaging, this would aid in further awareness to minimize any means of complexity in dental problems.

Tooth Abnormalities In Individuals With Unilateral Alveolar Clefts: A Comparison Between Sides Using Cone-Beam Computed Tomography.

BackgroundTooth abnormalities are most often present in individuals with oral clefts than general population, and lead to a long-term impact on facial anatomy and self-esteem. The purpose of this study was to compare the proportion of dental anomalies between the cleft side and non-cleft side in individuals with non-syndromic unilateral alveolar clefts (AC).Material and MethodsTwenty cone beam computed tomography (CBCT) scans were converted into three-dimensional (3D) virtual models. The dental anomalies considered were: tooth agenesis; supernumerary teeth; giroversion; and microdontia. Statistical analysis was performed using the McNemar’s test and Fisher’s exact test (p<0.05).ResultsStatistically significant differences were not found either between the prevalence of individuals with dental abnormalities on the non-cleft side and the sides of the AC (p = 1.00), or sex (p = 0.36). Tooth agenesis was the most prevalent dental anomaly (55.6%). On the cleft side the lateral incisor was tooth most involved by dental anomalies; and the second premolar was the most affected on the non-cleft side.ConclusionsThis study showed a high frequency of dental anomalies in the cleft individuals and indicated that the side of AC and sex do not interfere in the proportion of dental anomalies on non-cleft side. Key words:Cone beam computed tomography, Hypodontia, Tooth abnormalities.

Dental anomalies inside the cleft region in individuals with nonsyndromic cleft lip with or without cleft palate.

BackgroundIndividuals with non syndromic cleft lip with or without cleft palate (NSCL±P) present high frequency of dental anomalies, which may represent complicating factors for dental treatment. The aim of this study was to investigate the prevalence of dental anomalies inside cleft area in a group of Brazilians with NSCL±P.Material and MethodsRetrospective analysis of 178 panoramic radiographs of patients aged from 12 to 45 years old and without history of tooth extraction or orthodontic treatment was performed. Association between cleft type and the prevalence of dental anomalies was assessed by chi-square test with a significance level set at p≤ 0.05. ResultsDental anomalies were found in 88.2% (n=157) of the patients. Tooth agenesis (47.1%), giroversion (20%) and microdontia (15.5%) were the most common anomalies. Individuals with unilateral complete cleft lip and palate (CLP, p<0.0001), bilateral complete CLP (p=0.0002) and bilateral incomplete CLP (p< 0.0001) were more affected by tooth agenesis than individuals with other cleft types. The maxillary lateral incisors were the most affected teeth (p<0.0001). Conclusions The present study revealed a high frequency of dental anomalies inside cleft region in NSCL±P patients, and further demonstrated that patients with unilateral complete CLP and bilateral incomplete CLP were frequently more affected by dental anomalies. Moreover, our results demonstrate that dental anomalies should be considered during dental treatment planning of individuals affected by NSCL±P. Key words:Nonsyndromic cleft lip with or without palate, dental anomaly, tooth agenesis, microdontia.

Prevalence of Dental Anomalies in Patients with Nonsyndromic Cleft Lip and/or Palate in a Brazilian Population

Objective : Many studies have demonstrated a high frequency of dental anomalies in patients with cleft lip and/or palate. Because dental anomalies may complicate dental treatment, we investigated the prevalence of dental anomalies in a group of Brazilian patients with nonsyndromic cleft lip and/or palate. Design, Participants, Setting : Retrospective analysis was performed using clinical records of 296 patients aged between 12 and 30years with repaired nonsyndromic cleft lip and/or palate without history of tooth extraction and orthodontic treatment. Associations between oral clefts and presence of dental anomalies outside the cleft area were investigated. Results : Dental anomalies were identified in 39.9% of the nonsyndromic cleft lip and/or palate patients, and tooth agenesis (47.5%), impacted tooth (13.1%), and microdontia (12.7%) were the most common anomalies. Cleft lip patients were less affected by dental anomalies compared with cleft palate or cleft lip and palate patients (p = .057). Specifically, patients with unilateral cleft lip and palate were significantly more affected by dental anomalies than those with bilateral cleft lip and palate (p = .00002), and individuals with unilateral complete cleft lip and palate (p = .002) and complete cleft palate (p = .01) were significantly more affected by tooth agenesis than other cleft types. Agenesis of the premolars (p = .043) and maxillary lateral incisors (p = .03) were significantly more frequent in patients with unilateral complete cleft lip and palate. Conclusions : The present study revealed a high frequency of dental anomalies in nonsyndromic cleft lip and/or palate patients and further demonstrated that patients with unilateral cleft lip and palate were frequently more affected by dental anomalies than those with bilateral cleft lip and palate. Moreover, our results demonstrate that dental anomalies should be considered during dental treatment planning for individuals affected by nonsyndromic cleft lip and/or palate.

A Retrospective Longitudinal Study Regarding The Dental Anomalies Of Position With Eruptive Etiology

Abstract Objective: Given the high frequency of dental anomalies of position and the lack of preventive measures of surveillance and monitoring of the eruption of permanent teeth, the aim of this study is to evaluate the frequency of dental anomalies of position in children. Material and methods: We conducted a retrospective longitudinal study in the 2006-2012 period. Data were collected from the medical records and orthopantomography x-rays of 408 patients (230 female and 178 male) who presented to the Pedodontics-Orthodontics Clinic in Tîrgu Mureș. After applying the exclusion criteria, 77 patients remained in the study. Results: From the 77 patients, 57 had dental inclusions, 15 presented ectopic teeth, dental rotations have been observed in 2 patients, and midline diastema in 5 patients. Regarding sex distribution, there was a higher frequency of dental inclusions in women (39) than men (38). The frequency of dental inclusions, regarding dental groups, in a descending order was: maxillary canine, mandibular second premolar, mandibular canine, maxillary second premolar, mandibular first premolar, maxillary first premolar, maxillary lateral incisor, maxillary central incisor and maxillary and mandibular first molars. The frequency of dental inclusions in the dental support area had the highest rate in the 12-14 years age group. Conclusions: From all the studied dental anomalies, dental inclusions presented the highest frequency. Regarding the dental support area, most cases of dental inclusion were observed in the 12-14 years age group.

Prevalence of Dental Anomalies in Nonsyndromic Individuals with Cleft Lip and Palate: A Systematic Review and Meta-analysis

To assess whether individuals born with nonsyndromic oral clefts display a higher frequency of dental anomalies. A search of MEDLINE, BIREME, OVID ALL EMB Reviews, and The Cochrane Library was conducted. The methodologic quality of the papers selected was assessed and scored. Papers reporting observational controlled studies of nonsyndromic forms of oral cleft matched for dental anomalies in primary and/or permanent teeth were included without language restrictions. Eligible studies were scored as "A"-low risk of bias, "B"-moderate risk of bias, or "C"-high risk of bias and poor quality. Fixed and random effects models were used to aggregate individual odds ratios (OR) and to derive pooled estimates and 95% confidence intervals. Six studies fulfilled our selection criteria and were included in the meta-analysis. Three distinct subgroup analyses were carried out in terms of dental anomalies. In the tooth agenesis meta-analysis, a random effects model was used because of heterogeneity and showed a significant association between tooth agenesis and oral clefts (OR = 12.31; 95% confidence interval [CI] = 3.75 to 40.36). In the remaining analyses, the fixed effects model revealed a positive association between supernumerary (OR = 4.99; 95% CI, 2.58 to 9.64) and crown morphologic abnormalities (OR = 5.69; 95% CI, 3.96 to 8.19) with oral clefts. Most included studies were of low to moderate quality. Although general limitations in study design were observed, the evidence suggests that a higher number of dental anomalies in the permanent dentition are noted in individuals born with oral clefts.

Dental anomalies in the Japanese mole Mogera wogura from northeast China and the Primorsky region of Russia

Dental anomalies in the Japanese mole, Mogera wogura Temminck, 1842, from northeast China and the Primorsky region of Russia were examined based on 241 specimens. The most frequent dental anomaly was oligodonty, i.e., missing P2 (18 cases) or P3 (one case). Supernumerary teeth were observed in three cases, two of which were characterized by abnormal shapes. Morphological abnormalities in teeth (six cases) and an asymmetrically curved rostrum (one case) were also observed. Dental anomalies were found at higher frequencies in populations near the northern range limit of the species. This was not caused by size effects. We suggest that the high incidence of dental anomalies was the result of genetic drift, which increases in marginal populations. Considering the nature of subterranean mammals, our results suggest that the high frequency of dental anomalies in a marginal population could have initiated the evolution of dental formulae if parapatric or peripatric speciation occurs in such populations.
