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

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

Management of the Impacted Tooth with Dilacerated Roots – A Surgical Challenge

Abstract The impacted tooth poses a challenge to dental and oral surgeons due to its unpredictable morphology which leads to increased difficulty during its extraction. A particular type of morphology is the dilacerated root. The root morphology of the third molar, for example, is considered to be the most variable in the human dentition. Careful considerations should be made on impacted teeth with dilacerated roots. In addition to the type of impaction, proximity to the inferior alveolar nerve or the maxillary sinus, number of roots and shape of the roots should be assessed to enable correct decision-making and successful management of these impacted teeth. In this case series, successful surgical management of impacted teeth with dilacerated roots is presented and the definition, prevalence, aetiology, diagnosis, imaging of dilacerations and surgical methods to achieve successful removal of these teeth are described.

A Cone-Beam Computed Tomography-Based Evaluation of Root Dilaceration in Permanent Premolars: A Retrospective Study.

As a developmental disorder characterized by an abnormal bend and angle in the longitudinal axis of the tooth root, dilaceration can cause complications in routine dental procedures such as endodontics, orthodontics, and surgical treatments. The purpose of this study was to investigate the prevalence of dilaceration in maxillary and mandibular premolar teeth in a population of Shiraz city based on cone-beam computed tomography (CBCT). This is a retrospective cross-sectional study on 927 premolar teeth and 132 CBCT radiographs of patients obtained from four private radiology clinics in Shiraz (Iran). In this study, the presence, location, direction, and severity of dilaceration in premolar roots as well as its relationship with gender were investigated. Chi-square and Fisher tests were used to analyze the data. The results showed that 17% of the studied 927 teeth had dilaceration. The prevalence of dilaceration was significantly higher in women than in men (20.3% vs. 13.6%, p= 0.005). The dilaceration rates were significantly higher in the mandibular first and second premolar teeth (31.6% and 26%, p= 0.002) than in the other teeth. In addition, the highest prevalence was in the distal direction with mild severity in the apical third of the root (p< 0.001). According to the results of this study, the prevalence of dilaceration was relatively high in mandibular premolar teeth especially in women.

Prevalence And Distribution Pattern Of Dilacerated Tooth Among Orthodontic Patients Using Cone-Beam Computed Tomography: A Prospective Multicenter Study.

Objectives: The objectives of this study were to ascertain the prevalence, distribution pattern, and root shape of dilaceration for each type of tooth, and to examine the association between dilaceration and gender. Material and Methods: The study was carried out at multiple centers- College of Dentistry at Hawler Medical University, Azadi Dental Center and Khanzad Teaching Center in Erbil City, from 2019-2023. 1420 patients received treatment and were assessed, of which 389 individuals (age range 17-45 years) satisfied the inclusion criteria. Among these, 143 were males (36.8%), 246 were females (63.2%). Three orthodontists conducted clinical examinations using standard diagnostic techniques. Cone beam computed tomography (CBCT) was utilized to determine the location of root deviation, whether it was in the apical, middle, or coronal third of the root. Results: Statistical analyses employed Pearson's chi-square test and Fisher's exact test. The occurrence of root dilacerations in the jaw was highest in the third molars (79.5%), followed by first molars (6.8%), second molars (6.8%), and second premolars (6.8%). Root dilacerations were most prevalent in the lateral incisors (40.2%) within the maxilla, followed by the canine (26.1%) and central incisors (14.1%). Females had a higher prevalence of tooth dilacerations compared to males. The majority of dilacerations occurred at the apical region (66.1%), with the middle region accounting for 30.6% and the coronal region accounting for 3.3%. Conclusion: Based on these findings, it is advised that orthodontists conduct a thorough examination of dilacerated teeth during orthodontic treatments. CBCT can serve as a supplementary technique for identifying the arrangement of root dilaceration. Our findings highlight the significance of doing a diagnostic radiographic evaluation prior to devising a treatment plan for permanent teeth.

Age is a risk factor for long-term effects of chemotherapy on dental development in childhood cancer survivors

AimsTo evaluate dental anomalies in survivors of childhood cancer after chemotherapeutic and irradiation therapy at 0–6 years of age and compare it with healthy controls. Material and methodsRetrospective analysis was performed for 47 childhood cancer survivors aged below six years at time of diagnosis and minimum 14 years old at time of analysis. Cancertherapy-related information and dental case history, including x-rays and photographs, were evaluated. All teeth were dichotomously assessed for malformations like agenesis, microdontia, hypoplasia, and root dilacerations. ResultsWe identified six main malformations that were overpresented in childhood cancer survivors in comparison to control group. Of all evaluated teeth we detected 2.5% agenesis, 4% microdontia, 3.8% circular hypoplasia and 6.8% or 6.1% slender or shortened root, respectively. Findings were correlated to the age at start of therapy, showing a strong correlation between a young age under 36 months and the development of malformations. Furthermore, we can see a gap of root malformations for boys older than three years. ConclusionChildren who received cancer therapy are at high risk for diverse dental damages. The main risk factor for malformations is an age below 36 months. Sex has an influence on the occurrence of root malformation in older children.

Impacted third molar root abnormality with mandibular canal close position as a presupposing factor to inferior alveolar nerve trauma

The aim of the study is reducing the risks of surgical injury to the inferior alveolar nerve, by taking into account individual topographic and anatomical features, improving diagnostic methods, and techniques for removing retinated teeth with a close fit to the mandibular canal. An examination was conducted in the Department of Surgical Dentistry (CBCT/OPG) and surgical treatment of 223 patients, with a close fit of the roots of the retinated lower third molar to the mandibular canal. Microslips of teeth with roots intact during removal (n=96) of the main group and the control group (n=52) were prepared with a Micromet Remet manual petrographic machine. The sections were carried out along the longitudinal axis of the tooth with the capture of the area of close fitting of the nerve, the teeth from the control group were sawed longitudinally along the axis of the root. The measurement of the macroanatomic features of the roots was carried out with a micrometer (MCC-MP-100 0.001 electronic «CHEESE», manufactured in the Russian Federation), measurements of the thickness of dentine and cement tissues on macroglyphs were carried out using a microscope calibration ruler with an accuracy of 0.01 mm. In the main group, three types of attachment of the mandibular canal to the root of the third molars were distinguished: 20 (96) cases of inter-root attachment of the mandibular canal, 42 (96) apical, 34 (96) lateral (buccal and lingual). A number of anomalies in the structure of the roots of the third molars have been revealed, which are a factor in injury to the neurovascular bundle of the mandibular canal during tooth extraction. The surface of the roots, as well as the microscopes of the tooth sections adjacent to the mandibular canal, were studied under a microscope. A number of specific anomalies of the roots of retinated third molars formed by root dilaceration, thinning of cement tissues, hypercementosis, which are formed at the site of the mandibular canal.In the presence of a deep indentation on the root of the tooth, as well as in the presence of areas of apical hypercementosis in the form of a «spike», the probability of nerve injury during tooth extraction increases many times, which must be taken into account when removing retinated third molars.

Mandibular First Premolar with Unusual Root and Canal Variation Associated With Condensing Osteitis or Sclerosing Osteitis–A Rarest Case Report

The present article reports existence of severe root dilaceration (80-degree bend) and Vertucci’s type V root canal configuration in the mandibular first premolar which is rarely reported in the dental endodontic literature. In addition to this, development of a localized condensing osteitis involving the same tooth which is rarely reported till date is also presented. Condensing osteitis was accidentally detected following radiographic examination of the first premolar and this clinical condition usually involves the tooth with a long-standing pulpal infection and occurs as a result of body’s defence mechanism against the infection. This radiopaque jaw pathology represents a bone deposition phenomenon rather than a bone destruction, a reactionary process seen following an inflammatory process in the tooth.

Associations across 22 dental and craniovertebral anomalies or variations, sagittal skeletal relationships, and vertical growth patterns: a comprehensive epidemiological study of 43 dentoskeletal traits

IntroductionDespite researchers' recent interest in identifying links between some dental and craniovertebral abnormalities, there are many important, unassessed gaps in our knowledge of this matter. In addition, previous samples were small. This large study aimed to examine, for the first time, the occurrence/severity of numerous dental and skeletal anomalies or variations and their correlations with each other and with growth patterns.MethodsThis epidemiological study was conducted on pretreatment radiographs of 1194 patients from 3 cities (815 females). Skeletal sagittal skeletal relationships and vertical growth patterns were determined. The occurrence/severity were assessed for: cervical vertebral fusion (CVF), atlas posterior arch deficiency (APAD), ponticulus posticus (PP), sella turcica bridging (STB), hypodontia, oligodontia, hyperdontia, missing of maxillary laterals, microdontia, macrodontia, root dilaceration, odontoma, taurodontism, dental fusion, dental gemination, enamel pearl, permanent molar ankylosis, primary molar ankylosis, dens in dente, dens invaginatus, dental impaction, ectopic eruption, and dental transposition. Incidental findings were recorded as well. Concurrent anomalies, sex dimorphism, and correlations across variables were examined statistically, adjusting for the false discovery rate (α = 0.05).ResultsPrevalence was calculated for 43 dentoskeletal traits/anomalies (22 abnormalities/variations [plus their severities/types] as well as 21 incidentally found traits/anomalies). Dental impaction may be more common in hyperdivergent and severer cases of sella bridging; also, primary molar ankylosis was associated with missing teeth. Dental impaction was associated only with STB and not with PP, APAD, or vertebral fusion. The only association observed among the four skeletal anomalies was seen between APAD and CVF. Merely the variables ‘sagittal skeletal relationships, vertical growth patterns, PP, and APAD’ showed sexual dimorphism; of these, only vertical growth pattern and APAD remained sexually dimorphic after adjusting for the FDR; still, the other two remained marginally significant and worth further evaluations. Sex dimorphism did not exist in concurrent abnormalities. The skeletal Class III was associated with the concurrent occurrence of craniovertebral, dental, and dentoskeletal abnormalities. Skeletal Class I was associated with fewer occurrences of concurrent dental anomalies. Vertical growth patterns were not associated with concurrent dental or dentoskeletal anomalies. However, the hyperdivergent pattern was associated with fewer cases of concurrent craniovertebral abnormalities.ConclusionsSTB and hyperdivergent pattern were associated with dental impaction. However, APAD, CVF, or PP were not associated with dental impaction. APAD was associated with CVF. Sexual dimorphism existed conclusively in the case of vertical growth patterns and APAD. Concurrent abnormalities (dental, skeletal, and dentoskeletal) were associated with skeletal Class III.

Characteristics of Unilaterally Impacted Maxillary Canines and Effect on Environmental Tissues: A CBCT Study.

The prognosis of orthodontic treatment for a patient with impacted canine teeth can be affected by many factors and understanding some of the characteristics of impacted teeth can increase the effectiveness and reduce the duration of treatment. This study aims to explore the effects of positions and dentoalveolar morphological characteristics of impacted maxillary canines on the prognosis of orthodontic treatment. In this study, forty-six adolescent individuals who applied for treatment of impacted teeth were divided into three groups: CC (no impacted maxillary canine group), BC (unilateral buccally positioned impacted maxillary canine group), and PC (unilateral palatally positioned impacted maxillary canine group). The impacted canine and adjacent teeth were evaluated in terms of position, angulation, inclination, mesiodistal and buccolingual widths, root length, dilaceration angle, and root resorption. The mean values of U3 Ang (angulation of the maxillary impacted canine) and U3/U2 angles (maxillary impacted canine and lateral incisor angle) were statistically significantly higher in the BC and PC groups (p < 0.001). The mean values of U2 RL (lateral incisor root length) and U3 RD (canine root dilaceration angle) were statistically significantly lower in the BC and PC groups. The results of this study suggest that shorter root lengths and increased angulation values may lead to the ectopic eruption of canines. The higher canine angulations in the PC group increase the degree of root resorption.

Evaluation of Root Dilaceration in Permanent Anterior and Canine Teeth in the Southern Subpopulation of Iran Using Cone-Beam Computed Tomography.

Developmental anomalies such as dilacerations can affect the eruption pattern of permanent anterior teeth. They are characterized by a curvature in the crown and roots of the teeth relative to their normal axis. This anomaly can cause some complexities in routine dental treatments such as root canal treatment, orthodontics, and surgery. The purpose of this study was to assess the prevalence of dilaceration in maxillary and mandibular anterior and canine teeth in Shiraz, Iran using cone-beam computed tomography (CBCT). In this retrospective study, a total of 1537 encompassed 400 CBCT images collected from 4 private radiology clinics in Shiraz were assessed. Each tooth was radiographically examined in order to diagnose root dilacerations considering their location (apical, middle, coronal), position in the jaw (maxillary or mandibular), direction (mesial, distal buccal and palatal/lingual), and severity of dilaceration (mild, moderate, and severe). The obtained data were analyzed by Chi-square statistical test and Fisher's exact test. In this study, out of 1537 studied teeth, 5.98% had dilaceration. The maxillary and mandibular canine teeth (9.8% and 9.7%, respectively) were significantly the most common teeth involved in this anomaly (p< 0.001). The distal direction with mild severity in the apical third of the root was also the most common result obtained from this study (p<0.001). In addition, there was no statistically significant relationship between gender and type of jaw regarding the prevalence of dilaceration in the studied dental groups (p=0.670 and p=0.231, respectively). In the current research, it was demonstrated through CBCT records that the prevalence of dilaceration in maxillary and mandibular anterior and canine teeth is relatively uncommon. The most prevalent dilaceration was found to be distal direction with mild severity in the apical third of the root.

Appropriate timing of treatment contributes to better root development of impacted anterior teeth in children

This study investigated the effects of different timings of orthodontic treatment on the root development of impacted anterior teeth in children. The cone-beam computed tomography (CBCT) data of 45 children with impacted anterior teeth were divided into unformed root (UR) group or basically formed root (BFR) group to evaluate root length (RL) and root growth length (RGL) of impacted teeth and contralateral nonimpacted teeth pretreatment and posttreatment. In addition, 22 patients with impacted dilaceration were selected to assess the effects of the crown-root angle and root development stage on RL and RGL. The Student t test, Wilcoxon test, analysis of variance, and multiple linear regression analysis were used for statistical evaluations. The RL of treated impacted teeth pretreatment and posttreatment was significantly shorter than contralateral nonimpacted teeth values (P<0.05). Posttreatment, the RL and RGL of impacted teeth of the UR group were significantly greater than those of the BFR group (P<0.05). The RGL of the dilacerated root in the UR group was considerably higher than in the BFR group (P<0.05). The larger crown-root angle group had a longer posttreatment RL (P<0.05). Multiple linear regression analysis revealed that the Nolla stage of impacted teeth and RL of contralateral teeth pretreatment significantly influenced the RL of impacted teeth posttreatment. Prompt orthodontic treatment is necessary for children with impacted anterior teeth to release the impacted state and achieve better root development. The root length of a dilacerated tooth continued to develop under treatment, but the crown-root angle partly constrained it.

Root Dilaceration Using Deep Learning: A Diagnostic Approach

Understanding usual anatomical structures and unusual root formations is crucial for root canal treatment and surgical treatments. Root dilaceration is a tooth formation with sharp bends or curves, which causes dental treatments to fail, especially root canal treatments. The aim of the study was to apply recent deep learning models to develop an artificial intelligence-based computer-aided detection system for root dilaceration in panoramic radiographs. A total of 983 objects in 636 anonymized panoramic radiographs were initially labelled by an oral and maxillofacial radiologist and were then used to detect root dilacerations. A total of 19 state-of-the-art deep learning models with distinct backbones or feature extractors were used with the integration of alternative frameworks. Evaluation was carried out using Common Objects in Context (COCO) detection evaluation metrics, mean average precision (mAP), accuracy, precision, recall, F1 score and area under precision-recall curve (AUC). The duration of training was also noted for each model. Considering the detection performance of all models, mAP, accuracy, precision, recall, and F1 scores of up to 0.92, 0.72, 0.91, 0.87 and 0.83, respectively, were obtained. AUC were also analyzed to better understand where errors originated. It was seen that background confusion limited performance. The proposed system can facilitate root dilaceration assessment and alleviate the burden of clinicians, especially for endodontists and surgeons.

Morfologjia e rrënjëve dhe kanaleve të molarëve të tretë të poshtëm në popullatën e Mitrovicës – studim in vitro

For successful endodontic therapy, full knowledge of the morphology of the root canal is required, especially for complex cases such as lower third molars. The aim of this study was to investigate the root and canal morphology of mandibular third molars in Mitrovica. From our dental office in Mitrovica, 175 extracted mandibular third mo- lars were randomly selected. Each tooth was meticulously cleaned before the root canal anatomy and morphology were carefully examined. Under dental loupe at a 2.5x magnification, mandibular third molars were examined for root number and morphology, number of canals per root, root canal configuration according to the Vertucci classification, incidence of dilacerated roots, and C-shaped canals. 16.43% of the 175 mandibular third molars exam- ined had a root. Sixty-eight percent of the teeth had two roots. Three roots were present in 11% of the teeth. In this study, 4% of the teeth had four roots, while in 4% of cases the C-shaped canals were reported. Also, 6.5% of cases had a dilacerated root. Despite the fact that the anatomy and morphology of the root canal of the mandibular third mo- lar is quite different, these teeth generally have two roots in most cases.

Prevalence, distribution, and clinical relevance of nonsyndromic dental anomalies in the general population of Uttar Pradesh, India: A radiographic study

Objectives: The objective of the study was to learn about the incidence of dental defects in our area and to assist dental surgeons and patients in achieving a better treatment outcome. Materials and Methods: Between March 2021 and March 2022, panoramic radiographs of 5140 patients attending the Department of Oral Medicine and Radiology, Subharti Dental College, Meerut, Uttar Pradesh, were examined, and this number of patients was included in the study based on the existence of dental anomalies. The participants in this study ranged in age from 8 to 60 years old. The study eliminated patients with syndromes linked to dental anomalies, and no clinically investigated dental malformations were included in the study. In patients visiting the hospital’s dental outpatient department, assessment of the prevalence and distribution of dental anomalies (i.e., tooth-by-tooth distribution) was performed. Results: Patients with dental malformations were discovered with the greatest proclivity for dilaceration (53.07%). Impacted mandibular teeth were the second most common anomaly found. Hypercementosis, dwarf roots, macrodontia, and microdontia were also found to be more prevalent. Conclusion: In a non-syndromic adult Indian population of Uttar Pradesh, the prevalence and distribution of several developmental dental abnormalities were discovered. Impaction, hypercementosis, dwarf roots, hyperdontia, root dilaceration, peg-shaped laterals (microdontia), and hypodontia were more common than other size and shape anomalies. These anomalies have a considerable impact on tooth occlusion and alignment, which has an impact on orthodontic treatment planning. They aid in the diagnosis of various systemic disorders and syndromes, as well as surgical planning. If not addressed effectively, they may bring treatment challenges.

Retrospective evaluation of traction time for impacted dilacerated maxillary central incisors in mixed dentition

PurposesThis study aimed to contribute to understanding the factors affecting the time of traction treatment of impacted dilacerated maxillary central incisors. MethodsThis retrospective study included children aged 8 – 11 years with a history of trauma, who applied to the pediatric dentistry clinics of Marmara University, School of Dentistry, between December 2013 and December 2019, and were treated for unilateral impacted dilacerated maxillary upper central incisors. Children's age, sex, digital panoramic radiographs, cone-beam computed tomography, and intraoral photographs were retrieved from electronic dental health records. The effects of children's age, sex, the direction of impacted teeth, distance of the teeth to the top of the alveolar crest, and root dilaceration level on traction time were analyzed by Mann-Whitney U test and Spearman's rank correlation coefficient test. ResultsThe inverse position of the incisors significantly increased the traction time (P = 0.012). However, the traction time did not differ according to the sex of the children (P = 0.707) or the level of root dilaceration (P = 0.429). No correlation was observed between the traction time and the age of children (P = 0.644) or the distance of the incisors from the top of the alveolar crest (P = 0.397). ConclusionsIn cases of the forced eruption of for the impacted dilacerated maxillary central incisors, the direction of the teeth should be evaluated when deciding on the treatment plan, as it may affect the treatment time.

Prevalence of Dental Anomalies and Its Role in Sex Estimation among Children of Jazan Region, Saudi Arabia

This study aimed to ascertain the prevalence of dental anomalies and their ability to estimate sex status. This cross-sectional radiographic study was based on the evaluation of dental anomalies of Saudi children aged between 5 and 17 years. A total of 1940 orthopantomograms (OPG) were screened, of which 1442 were included. All the OPGs were digitally evaluated with ImageJ software. The demographic variables and dental anomaly findings were subjected to descriptive and comparative statistical analysis. Discriminant function analysis was conducted for sex estimation. p value < 0.05 was considered as significant. The mean age of the children in this study was 11.35 ± 0.28 years. At least one dental anomaly was detected in 161 children (11.17%), including 71 males and 90 females. Only 13 children (8.07%) presented with more than one anomaly. The most common dental anomaly detected was root dilaceration (47.83%) followed by hypodontia (31.68%). The least common dental anomaly was infraocclusion (1.86%). The sex prediction accuracy using discriminant function analysis was 62.9% (p < 0.01). The prevalence of dental anomalies was 11.17% with root dilaceration and hypodontia being the most common. The role of dental anomalies in sex estimation was found to be ineffective.

MULTIDISCIPLINARY APPROACH OF IMPACTED PERMANENT MAXILLARY LEFT CENTRAL INCISOR AND CANINE

ABSTRACT Background: The permanent maxillary canines have significant incidence of impaction, being the most affected teeth after the third molars, while impacted maxillary insicor is the third most commonly impacted tooth. Objective: This case report is about a multidisclipinary orthodontic treatment of 12 years old female with chief complaint of unerupted anterior upper teeth. Case: A case with unerupted of permanent maxillary left central incisor tooth and permanent maxillary left canine tooth, with Angle Class 1 molar relation and crowded of mandibular teeth. Panoramic and occlusal radiograph showed impacted 21 tooth with severely root dilacerations and impacted 23 tooth in palatal and horizontal position. Case Management: The patient was treated with Edgewise technique. Surgical approach was applied 3 months after levelling and unravelling stage to extract 21 tooth due to its severely root dilaceration and to bond lingual button on palatal side of 23 tooth. Orthodontic traction of impacted 23 tooth was applied a week after being exposed to the position of 21 tooth. Thirteen months after traction, 23 tooth was totally erupted and need 8 additional months to reach its final position. The crown of 23 was reshaped with porcelain fused to metal crown and 63 tooth was left still and got conservative treatment with composite. Conclusion: Orthodontic traction and reshaping of impacted 23 tooth was succeeded to replace the position of 21 tooth with good occlusion and esthetic. Based on OPG after treatment, all teeth were in good root paralleling. The patient was satisfied with good occlusion and esthetic.

Internal root resorption: case report and literature review

Abstract: Internal inflammatory root resorption (IIRR) is a rare, but significant consequence of dental trauma. Previous cases often focus on two-dimensional imaging. More widespread use of cone beam computed tomography (CBCT) has seen improved diagnostic accuracy of these defects leading to more appropriate management. In this case report, an adolescent male patient complained of a missing front tooth (UR1). Dental history revealed intrusive trauma to the predecessor as a child. The UR1 was impacted with a dilacerated root. CBCT imaging revealed severe internal root resorption, and due to its extensive nature, extraction was advised. CPD/Clinical Relevance: Readers should be aware of the consequences of internal inflammatory root resorption and understand the importance of early detection with appropriate special investigations.

Evaluation of Root Dilaceration and Taurodontism in Children with and without Cleft Lip and Palate

Taurodontism and root dilaceration are developmental anomalies. Both taurodontism and dilaceration might be related with cleft lip and palate (CLP). This study aimed to investigate the prevalence of taurodontism and root dilaceration, in the children with CLP. Cone beam computed tomography images of 200 children (100 cleft 100 healthy) with CLP were evaluated retrospectively. Taurodontism level was divided into three subtypes as hypertaurodont, mesotaurodont and hypotaurodont. Root dilaceration was recorded if the tooth has completed apexification process. The frequency of taurodontism was found to be 30% in children with CLP and 12% in the control group. The frequency of root dilaceration was found to be 31% in children with CLP and 12% in children without CLP. Incidence of both root dilaceration and taurodontism was found higher in children with CLP (P

Prevalence and distribution of diverse dental anomalies in an Egyptian children's population

Aim In normal dental exams, dental anomalies are widespread. It may lead to occlusal, cosmetic, and functional problems. In this study, the prevalence and distribution of developmental dental abnormalities in a community of Egyptian children were studied. Patients and methods The average age of the sample was 7.5 years out of 2583 panoramic radiographs of kids between the ages of 6 and 12 that were analyzed, including 1110 boys and 1473 girls. The digital panoramic radiographs were examined by two experienced researchers in a standard manner and in good lighting for the following developmental anomalies: congenitally missing teeth, extra teeth, impaction, ectopic eruption, transposition, gemination, fusion, submerged, peg-shaped teeth, dilacerations, taurodontism, dens in dente (Dens Evaginatus), retained or early loss of primary teeth considering the chronological age of dental eruption, and any other anomalies. Results Two hundered sixty-six panoramic radiographs, or 10.3% of the study group, had at least one dental abnormality, while 2317, or 89.7%, had none. There was no significant difference between the sexes other than fusion, where the rate was higher in females than in males among the cases with dental anomalies. Of these cases, 57.14% were girls and 42.85% were boys. Supernumerary teeth were more common than congenitally lacking teeth (1.85 vs. 4.41%). Amelogenesis imperfect, transposition peg-shaped and halted teeth, impacted teeth (1.5%), taurodontism (1.16%), root dilacerations (1.04%), amelogenesis imperfect, fusion (0.23%), and no cases of accessory roots and dentinogenesis imperfecta were found in this study. Conclusion Dental anomalies were often found in this Egyptian study population. Various dental abnormalities were found. Congenital missing was the most frequent anomaly, followed by extra teeth, impacted teeth, taurodontism, root dilatation, fusion, amelogenesis imperfecta, transposition peg-shaped teeth, and arrested teeth, in that order. In this investigation, no instances of dentinogenesis imperfecta or accessory roots were found. Because of the high occurrence of developmental dental anomalies, it is imperative that their causes be better understood to provide better treatment, intervene earlier, and prevent future problems.
