Bilateral Dens Invaginatus Research Articles

Prevalence of dens invaginatus and its association with periapical lesions in a Western Indian population-a study using cone-beam computed tomography.

This study aimed to assess the prevalence of dens invaginatus (DI) and its association with periapical lesions (PLs) in a Western Indian population by means of cone-beam computed tomography (CBCT). CBCT volumes of 5201 subjects were evaluated. Associations among gender, tooth type, DI type (Oehler's classification), and presence of PL were investigated. PL was codified using Estrela's Cone Beam Computed Tomography Periapical Index (CBCTPAI). Chi-square tests and descriptive statistics were used at p = 0.05. Overall, 7048 CBCTs were assessed, containing 19,798 maxillary and mandibular anteriors, of which 77 maxillary teeth demonstrated DI (0.39% of all anteriors). Of all 5201 subjects, 57 had DI (1.1%). Bilateral DI was more common in females than in males (p = 0.046). DI type distribution was as follows: type I (22.1%), type II (61.03%), type IIIa (10.4%), and type IIIb (6.5%), which was significantly different (p < 0.001). Maxillary lateral incisors were the most associated with PL (p < 0.001). Type I was frequently associated with CBCTPAI scores 1 and 2 (absence of PL), whereas types II, IIIa, and IIIb were associated with CBCTPAI scores 3, 4, and 5 (presence of PL). A prevalence of 1.1% identifies DI as a common developmental tooth anomaly in a Western Indian subpopulation. The percentage of maxillary anteriors affected by DI and associated PLs should be considered before diagnosis and treatment planning. Knowledge about the prevalence of DI and its subtypes, and their association with/without periapical pathosis may aid clinicians in treatment planning and execution to improve patient outcomes.

Assessment of dens invaginatus and its characteristics in maxillary anterior teeth using cone-beam computed tomography

This cone-beam computed tomographic (CBCT) study aimed to evaluate the prevalence of dens invaginatus (DI) and its characteristics in maxillary anterior teeth in a Saudi population. A total of 505 CBCT scans were evaluated, including a total of 2790 maxillary anterior teeth. The patients’ demographic data, including age and sex, were recorded. The presence of DI and the related characteristics including bilateral occurrence; DI type according to Oehlers classification; and presence of periapical radiolucency, open apex, and/or nearby impacted teeth were analyzed. The associations between DI and the other factors were analyzed using the chi-square and fisher exact tests. DI was detected in 7.3% of the patients and 1.6% of the teeth examined. Most of the DI-affected teeth were maxillary lateral incisors (76.1%), followed by mesiodens (19.6%) and maxillary central incisors (4.3%), while no DI was observed in the maxillary canines. Bilateral DI was found in 24.3% of the affected patients. Oehlers type I DI was the most frequent (80%). Periapical radiolucencies, open apices, and nearby impacted teeth were observed in 10.9%, 4.3%, and 30% of the invaginated teeth, respectively. DI was significantly associated with tooth type (P < 0.0001) but not with sex (P > 0.05). Although most of the DI cases are limited to the crown, CBCT imaging is essential for DI evaluation and management.

Investigation of dens invaginatus in a Chinese subpopulation using Cone-beam computed tomography.

This study assesses the prevalence and characteristics of dens invaginatus (DI) in a sample of Chinese population by using cone-beam computed tomography (CBCT) images. A retrospective study was conducted by using the CBCT images of 1,004 patients. The whole dentition was evaluated for the presence and characteristics of DI. Periapical pathosis status and bilateral feature of affected teeth were also examined. Dens invaginatus was observed in 85 of 1,004 subjects, with a prevalence of 8.47% and a tooth prevalence of 0.494%. Males presented a higher prevalence of DI than females (p=.011). Type I DI was the most commonly observed type of dens invaginatus, followed by type II and type III. The structure form of different types of DI was various. Overall 2.48% of the patients with type I DI, 5.88% of the patients with type II DI, 100% of the patients with type III DI had apical pathosis. Bilateral DI was found in 63.53% of the affected patients. This study indicates that DI was not rare, and clinicians should be aware of its existence. CBCT examination can provide an accurate representation of dental anatomy and should be incorporated into early diagnosis and treatment planning for teeth with DI.

Incidental Finding of Bilateral Dens Invaginatus in the Maxillary Lateral Incisors and Role of Cone Beam Computed Tomography in Diagnose and Treatment

Dens invajinatus (DI), mine organinin dis gelisimi sirasinda bitisigindeki dental papillaya dogru katlanmasi sonucu olustugu dusunulen bir dental malformasyondur. Morfolojik olarak genis bir varyasyon yelpazesi gosterir ve siklikla maksiller lateral disleri etkiler. Bu calismada, rastlantisal radyolojik bulgu olarak tip 1 DI tespit edilen maksiller lateral disler ve periapikal lezyonu olan curuksuz sag maksiller lateral dis ve bu disin cerrahi olmayan endodontik tedavisi anlatilmaktadir

Bilateral dens invaginatus in the mandibular premolars - Diagnosis and treatment

Dens invaginatus (DI) is a developmental anomaly that results from an infolding of the dental papilla during tooth development and simulates the appearance of a tooth within another tooth. It shows a wide spectrum of variations in morphology and usually affects the maxillary lateral incisors. This study presents an unusual case of an Oehlers’ Type I DI involving the bilateral mandibular first and second premolars, which presented as an incidental radiographic finding in the first premolars and was associated with a periapical lesion in the second premolars which was successfully treated using nonsurgical endodontics.

Prevalence of dens invaginatus in Jordanian adults.

To assess the prevalence of dens invaginatus in a sample of Jordanian dental patients. The data were collected from examination of 3024 radiographs from a random sample of 1660 patients showing 9377 teeth. A tooth was considered having dens invaginatus if an infolding of a radiopaque ribbon-like structure equal in density to enamel was seen extending from the cingulum into the root canal. Teeth with dens invaginatus were found in 49 subjects out of 1660 subjects examined; thus, the person prevalence was 2.95%. Bilateral dens invaginatus was seen in 12 patients, whereas unilateral dens invaginatus was demonstrated in 37 patients. Dens invaginatus was detected in 61 teeth out of a total of 9377 for a tooth prevalence of 0.65%. Maxillary lateral incisors were the most common teeth affected with the condition (90% of cases). Dens invaginatus is not common, but it is an important anomaly. The availability of such data may alert the dental practitioner to anticipate the percentage of teeth having difficulties during endodontic treatment.

Multiple dental anomalies in the maxillary incisor region

A patient with multiple anomalies of the maxillary teeth, including shovel-shaped incisors, talon cusp, bilateral dens invaginatus and bilateral peg-shaped supernumerary incisors is reported. The patient also exhibited Carabelli's cusp on both maxillary first molars. No developmental syndrome was identified. This very unusual combination of anomalies has not been reported previously.

Multiple bilateral dens invaginatus and an impacted cuspid in the maxillary incisor region. Case report

A case of multiple bilateral dens invaginatus in the maxillary incisor teeth and an impacted cuspid has been presented. The impacted cuspid was removed surgically.

Bilateral dens invaginatus with associated radicular cysts: A case report

A case report is presented describing bilateral dens invaginatus of the maxillary lateral incisors. Pulpal disease of the lateral incisors resulted in radicular cysts with the right cyst expanding to cause the eventual loss of four teeth. Removal of the cysts was followed by normal healing. Early detection of the bilateral dens invaginatus might well have resulted in successful interceptive care.

Bilateral dens invaginatus in the mandibular incisor region

A case of bilateral dens invaginatus in the mandibular incisor regions has been reported. Radiographs demonstrated invaginations in both of the incisors in the mandibular incisor region and also demonstrated a periapical radiolucency. Clinical examination revealed two anomalous incisors and apparently there was congenital absence of two mandibular incisors. Dens invaginatus in the mandibular incisors would appear to be a most unusual occurrence.

Double bilateral dens invaginatus in the maxillary incisor region

Two cases of bilateral double dens invaginatus in the maxillary incisor region have been reported. One of the patients (Case 1), a 12-year-old boy, had double invaginations in both of the erupted teeth in the maxillary lateral incisor region. The other patient (Case 2), a boy 8 years of age, had double invaginations in each of the two partially developed supernumerary teeth that were impacted in the palate in the maxillary central incisor region. Double bilateral dens invaginatus would appear to be a most unusual occurrence.
