RESUMEN

El diente invaginado (DI) es una alteración en el desarrollo del órgano dentario, el cual se produce a consecuencia de una invaginación del epitelio interno del órgano del esmalte, también conocido con otros nombres, entre ellos dens in dent. Tiene una serie de características clínicas, histológicas e imagenológicas debidamente descritas a través de la literatura. Su variante más extrema presenta una configuración muy compleja y, debido a la magnitud de la invaginación que presenta, se le denomina también odontoma dilatado, término que para algunos profesionales genera confusión.Este término ha sido mencionado como sinónimo tanto de DI como, en algún momento, de una nueva variante de odontomas, si bien existe una diferencia entre ambos tipos: uno es una anomalía del desarrollo y el otro, un crecimiento de aspecto hamartomatoso. Sin embargo, la literatura sigue utilizando ambos términos para definir al DI, por lo que es importante conocer el origen y tener claro que la controversia está basada en referencias históricas y de costumbre. (AU)


The invaginate tooth (IT) is an alteration in the development of the dental organ, which occurs as a consequence of invagination of the internal epithelium of the enamel organ. IT is also known as "dens in dente", among other denominations, and presents a series of clinical, histological and imaging characteristics. The most extreme variant of IT has a very complex configuration, and the magnitude of the intussusception has led to it also being called dilated odontoma, being a term that generates confusion in some professionals.While the term odontoma has been reported as a synonym for both IT as well as a new variant of odontomas, there is a difference betweene the two types: one is a developmental anomaly and the other is a growth with a hamartomatous appearance. However, the literature continues to use both terms to define IT, and thus, it is important to know the origin and be aware that the controversy is based on historical and customary references.

RESUMEN

Dens invaginatus (DI), which often occurs in the maxillary lateral incisor, is an important issue in endodontics because the treatment complexity increases depending on the degree of invagination and the vitality or nonvitality of the pulp. An 11-year-old female patient with a sinus tract in the gingiva of the maxillary lateral incisors showed peri-invagination periodontitis and double DI on radiography. Cone-beam computed tomographic imaging was used to examine the structure in the root canal in detail, and Oehlers type IIIA and IIIB DI was found. It was also shown that the patient's bone defect was caused by type IIIA. Because a healthy reaction was observed in the pulp test, the final diagnosis was peri-invagination periodontitis associated with type IIIA of the double DI with vital pulp. We expected the lesion to heal by treating only the type IIIA invaginated pseudo-root canal while preserving the healthy pulp. The invaginated root canal was cleaned under a microscope using ultrasonic instruments and nickel-titanium files to minimize irritation to the pulp. Because the lesion shrinkage was confirmed by cone-beam computed tomographic imaging taken 3 months after the start of treatment, vertical compaction of the warm gutta-percha technique was performed. At the 6-month postoperative recall, the pulp was normal, and the lesions were further improved. Treatment of the main root canal of double DI is complicated. However, proper diagnosis and careful cleaning of the invaginated root canal are essential for healing while preserving the pulp.

RESUMEN

Los dientes supernumerarios y la fusión dental son anomalías del desarrollo dental cuyas causas aún no se han dilucidado con certeza. El cuarto molar inferior, también denominado distomolar, es uno de los dientes supernumerarios con menor frecuencia de aparición clínica y su fusión con el tercer molar es una condición todavía menos común. A continuación, se reportan los casos clínicos de tres pacientes masculinos que presentaron fusión del tercer molar inferior derecho con un distomolar tratados mediante odontectomía (AU)


Supernumerary teeth and dental fusion are abnormalities of dental development whose causes have not yet been elucidated with certainty. The lower fourth molar, also called distomolar, is one of the supernumerary teeth with the least frequency of clinical appearance and its fusion with the third molar is an even less common condition. Next, the clinical cases of three male patients who presented fusion of the right lower third molar with a distomolar treated by odontectomy are reported (AU)

RESUMEN

Dens invaginatus (DI) is a developmental anomaly resulting in a deepening or invagination of the enamel organ into the dental papilla prior to calcification of the dental tissues. Presence of DI is considered to increase the risk of caries and pulpal pathology, but they are often missed in the initial orthodontic assessment as they present with no clinical signs of an anomaly. In absence of adequate oral hygiene and maintenance, bacterial contamination of these malformations can lead to the development of early caries and consequent pulpal death. Early diagnosis of these lesions is critical as they can negatively impact any planned orthodontic treatment and assessment of the prognosis of these lesions is therefore necessary prior to the commencement of orthodontic treatment. In this article, we aim to illustrate the need for appropriate diagnosis and multidisciplinary approach in the management of DI in patients undergoing orthodontic treatment.

RESUMEN

BACKGROUND: Dens invaginatus is a developmental anomaly that can affect both deciduous and permanent dentition. The anomaly is caused by the invagination of the enamel organ into the dental papilla prior to the calcification of the dental tissues. The treatment option changes according to the classification, from the simple filling of the invaginated enamel area to root canal treatment with or without retrograde surgery, intentional re-implantation, or the extraction of the affected tooth. CASE REPORT: In this study we report a case of a maxillary lateral incisor invaginatus in a young adult patient. The periapical endoral X-ray showed the presence of a periapical radiolucency in tooth 22, that had a structure similar to a tooth inside it and an immature apex. Cold thermal testing showed that it was not a vital tooth. CBCT confirmed the diagnosis of Oehler Class II dens invaginatus. The treatment plan involved root canal treatment of both the "true" and the "invaginated" canal using calcium hydroxide-based intermediate medication. Then, after removing the hard internal structure with the aid of an operative microscope, MTA was used to close the immature apex. Finally, the large endodontic space was filled with self-etching, self-adhesive, dual curing resin cement. The patient was included in a follow-up programme to monitor and verify the complete healing of the periapical bone of the affected tooth. CONCLUSION: The use of technology and of special materials allowed an adequate management and resolution of the case reported.

RESUMEN

A rare case of radicular dens invaginatus (dens in dente) was found during dental cleaning of a 5-year-old male Rottweiler dog. Radiographic examination revealed intense radiopacity, which extended from the crown to the apical root region of the affected tooth. Macroscopically, the crown of the left maxillary first molar tooth (209) had irregular and deformed buccal and lingual surfaces. Microscopic examination revealed dentine invagination in the pulp cavity in of the crown and root and pulp necrosis. Based on the gross, radiographic and histological findings, a diagnosis of radicular dens invaginatus was made.

RESUMEN

This article reports on an unusual case of dens invaginatus in a maxillary third molar that was causing severe symptoms of irreversible pulpitis. This malformation was not clinically or radiographically identified, and the occurrence of referred pain made the early identification of the responsible tooth difficult. Determination of the tooth that was the source of symptoms was only possible after an observation period and fast aggravation of the pathologic process to cause pulp necrosis and extreme tenderness to percussion. The diagnosis of dens invaginatus was made only after extraction and sectioning. Histopathologic and histobacteriologic features of this case are illustrated.

RESUMEN

Dens invaginatus (DI) is a developmental dental anomaly with complicated anatomical features and a broad spectrum of morphologic variations posing challenges of diagnosis and treatment to dental clinicians. Cone-beam CT (CBCT) can provide a more detailed 3D view of the complex anatomical variations in DI and help dental clinicians to verify the classification of DI and to improve the accuracy of diagnosis. A number of treatment planning options may need to be considered based on DI types, peri-radicular pathology involved and apical orifice closure status. Applications of modern endodontic techniques and novel materials may induce successful treatments and favorable outcomes. The aim of the present article is to review the etiology, classification and treatment outcome of DI and to provide guidelines of diagnosis and management of DI cases for dental clinicians.

RESUMEN

BACKGROUND: To report a case of type III dens invaginatus associated with peri-invagination periodontitis in an immature permanent mandibular central incisor with open apex, in which only the invagination area was treated and vitality was preserved. CASE PRESENTATION: A 9-year-old boy was referred complaining of pain in the mandibular left central incisor. After radiographic examination, an invagination into the pulp chamber of the tooth associated with periapical radiolucency was detected. Endodontic access was performed and the orifice was identified under a dental operating microscope. The invagination area was chemo-mechanically cleaned. After 1 week, the invagination was obturated with mineral trioxide aggregate. During the 2-year follow up period, the tooth was asymptomatic. Radiographic examination revealed significant progression of periapical healing and root development in the main root canal of the tooth. CONCLUSION: Non-surgical root canal treatment of the invagination may preserve pulp vitality, and continuous root development of the tooth.

RESUMEN

A radicular variant of dens invaginatus (DI) is a rare form of dens invaginatus which develops in the root of the tooth after the crown development is completed. This report involves successful management of a case with guided tissue regeneration and describes the cone beam computed tomography (CBCT) characteristics of true radicular DI. A 20-year-old woman reported with recurrent swelling and pus discharge associated with her maxillary left central incisor (#21). Cone beam computed tomography (CBCT) of the region revealed #21 had an invagination in the mesial aspect of the coronal third of the root with a para radicular low-density region perforating both the cortices. A diagnosis of true radicular variant of DI was made by exclusion. The case was managed with Biodentine® , platelet-rich fibrin and freeze-dried demineralised bone graft. A 2-year review showed that the tooth was functional with normal periodontal parameters and normal response to electric pulp sensibility test.

RESUMEN

This is a case of swelling originating from dens invaginatus associated with lateral incisor, misdiagnosed as a globulomaxillary cyst. The initial diagnosis of globulomaxillary cyst was made solely from radiographs by observing a reverse pear-shaped radiolucency between the lateral incisor and cuspid. The results following pulp testing and Cone Beam Computed Tomography (CBCT) evaluation revealed the endodontic origin of the lesion, which entailed the treatment carried out by surgical enucleation and apicoectomy. This also details the clinical and diagnostic dilemma as well as conflicts associated with the diagnosis and management of the cystic lesion.

RESUMEN

Dens invaginatus is a malformation affecting mainly the superior lateral incisors. It is defined as an infolding of the crown hard tissues, including the enamel and dentin, and can extend up to the root apex. Root canal treatment of this abnormality is considered difficult due to the complex anatomy presented by these teeth. This case series presents nonsurgical endodontic treatment in two cases of dens invaginatus (type II and III) in maxillary lateral incisors. This nonsurgical or conventional endodontic treatment results in healing of the periapical lesions associated with both cases, with no need for extra intervention e.g. surgical or invasive management. The manual instrumentation associated with sodium hypochlorite and calcium hydroxide were able to completely heal the lesions.  Radiographic exams were carried out to control and asses the healing. Nonsurgical treatment was successful in both cases with adequate repair after a 6-year follow-up with radiographic and tomographic assessments.

RESUMEN

We report a clinical case of type Ⅲ dens invaginatus with endodontic-periodontal lesion in a maxillary lateral incisor. The palatal radicular anomaly predisposed the tooth to periodontal lesions. The caries along the palatal groove caused tooth pulp necrosis and periapical lesions. By means of microscopic root canal therapy, apical surgery, and guided periodontal tissue regeneration, the apical and periodontal infection were controlled, and the affected tooth was retained.

RESUMEN

PURPOSE: To explore the diagnosis and clinical treatment of dens in dente. METHODS: Preventive resin restoration, root canal treatment, apical barrier technique and apexification were used to treat three cases of dens in dente, respectively. The curative effects were assessed by general examinations and imageological examinations during postoperative follow-up visits. RESULTS: Three patients with different type and degree of dens in dente achieved good therapeutic effect and favorable prognosis through different treatment methods. CONCLUSIONS: Dens in dente is complex clinically and the treatment is difficult. Clinicians should improve the understanding of dens in dente. The keys to successful treatment are early diagnosis and early treatment. In addition, it is important to take proper measures according to the type and degree of dens in dente, to preserve the diseased tooth as much as possible.

RESUMEN

A 3 year and 8 months old Chinese boy was referred for a consultation regarding his missing maxillary anterior teeth. He had a history of trauma to his primary maxillary anterior teeth due to a fall at the age of 16 months. Clinical examination of the patient indicated multiple carious lesions and inadequate oral hygiene. Radiographic examination revealed intrusion of the primary left lateral incisor, with evidence of damage to the permanent tooth germ. Subsequently, the patient was followed-up for almost six years during which his permanent maxillary left lateral incisor erupted exhibiting an unusual morphology. Clinically enamel hypoplasia and radiographically dens invaginatus were evident in affected tooth.

RESUMEN

BACKGROUND: To determine the association between developmental dental anomalies (DDA), early childhood caries (ECC) and oral hygiene status of 3-5-year-old children resident in Ile-Ife, Nigeria. METHODS: This was a cross-sectional study. We analyzed data for 3-5-year-olds extracted from the dataset of a household survey collected to determine the association between ECC and maternal psychosocial wellbeing in children 0-5-year-old. The outcome variables for the study were ECC and poor oral hygiene. The explanatory variable was the presence of developmental dental anomalies (supernumerary, supplemental, mesiodens, hypodontia, macrodontia, microdontia, peg-shaped lateral, dens evaginatus, dens invaginatus, talons cusp, fusion/germination, hypoplasia, hypomineralized second molar, fluorosis, amelogenesis imperfecta). The prevalence of each anomaly was determined. Poisson regression analysis was conducted to determine the association between presence of developmental dental anomalies, ECC and oral hygiene status. The model was adjusted for sex, age and socioeconomic status. RESULTS: Of the 918 children examined, 75 (8.2%) had developmental dental anomalies, 43 (4.7%) had ECC, and 38 (4.1%) had poor oral hygiene. The most prevalent developmental dental anomalies was enamel hypoplasia (3.9%). Of the 43 children with ECC, 6 (14.0%) had enamel hypoplasia and 3 (7.6%) had hypomineralized second primary molar. There was a significant association between ECC and enamel hypoplasia (p < 0.001) and a borderline association between ECC and hypomineralized second primary molars (p = 0.05). The proportion of children with poor oral hygiene (PR: 2.03; 95% CI: 0.91-4.56; p = 0.09) and ECC (PR: 2.02; 95% CI: 0.92-4.46; p = 0.08) who had developmental dental anomalies was twice that of children with good oral hygiene and without ECC respectively, although the differences did not reach statistical significance. CONCLUSIONS: Enamel hypoplasia and hypomineralized second primary molars are developmental dental anomalies associated with ECC. developmental dental anomalies also increases the probability of having poor oral hygiene in the population studied.

RESUMEN

INTRODUCTION: Dens invaginatus is an anomaly of dental development in which calcified tissues, such as enamel and dentin, are invaginated into the pulp cavity. This morphologic alteration is more frequent in maxillary permanent lateral incisors and makes them more susceptible to carious lesions and pulp alterations. METHODS: This case report describes a patient with maxillary lateral incisors affected by dens invaginatus. The maxillary right lateral incisor had already undergone endodontic treatment, and the maxillary left one had a periapical lesion. Additionally, the patient had a Class II Division 1 malocclusion, with anterior open bite, posterior crossbite, and an impacted mandibular left second molar. RESULTS: The orthodontic treatment involved extraction of the maxillary lateral incisors and 2 mandibular premolars, resulting in proper overjet and overbite with good arch coordination and occlusal stability. CONCLUSIONS: Treatment results were stable, as evaluated in a 6-year posttreatment follow-up.

RESUMEN

Los dientes pueden presentar trastornos originados por factores externos o hereditarios que afectan su forma. Dens in dente es una anomalía durante el desarrollo que resulta en la invaginación del esmalte y dentina, en la cara lingual o vestibular, que puede extenderse profundamente dentro de la raíz. El talón cuspídeo es caracterizado por la proyección de una cúspide accesoria en el cíngulo de los órganos dentarios anteriores y la superficie oclusal de los posteriores. Se presenta el caso de una niña de 7 años de edad, con dens in dente y talón cuspídeo en el incisivo central superior derecho que provoca interferencia oclusal prematura, sin sintomatología. Se realizó desgaste gradual del talón cuspídeo, con aplicación de fluoruro de sodio. El diagnóstico temprano de anomalías dentales en pacientes pediátricos es la clave para un tratamiento conservador y preventivo para el adecuado funcionamiento masticatorio y estético del paciente (AU)


Teeth may have disorders caused by external or hereditary factors that affect their shape. Dens invaginatus is an anomaly during development that results in invagination of the enamel and dentin, lingual or vestibular surface, which can extend deeply into the root. Talon cusp is characterized by the projection of an accessory cusp in the cingulate area in anterior and occlusal aspects of the posterior teeth. We present a case of a 7 year old girl with dens invaginatus and talon cusp on the maxillary central incisor that causes premature occlusal interference, without symptomatology. The treatment employed were gradual wear of cuspal talon with several applications of sodium fluoride. Early diagnosis in pediatric patients is the key to a conservative and preventive treatment for a proper masticatory and aesthetic functioning of the patient (AU)
