Management of the malposition tooth that was caused by dentigerous cyst associated with impacted supernumerary tooth by using an obturator

This report presents a case of eruption guidance for an upper right central incisor with a dentigerous cyst associated with an impacted supernumerary tooth in a 5-year-9-month-old boy. A swelling was seen in the region of an upper right central incisor. Radiographic examinations showed that a well-defined cystic lesion, containing an impacted supernumerary tooth crown in it, was located between the root of the primary upper right central incisor and a permanent upper central incisor germ. Under general anesthesia, the dentigerous cyst was removed at extraction of the upper impacted supernumerary tooth. And then, a socket was kept open wound. A histopathological examination confirmed the diagnosis of a dentigerous cyst associated with a supernumerary tooth. By using an obturator, we guided eruption of an upper right central incisor with malposition that was caused by the dentigerous cyst, and observed the way of the tooth eruption for two years and seven months. The obturator was inserted in the socket directly for three months until it was closed. After that, the obturator was used as only a removable space maintainer. Eight months after the operation, the obturator was removed because the upper left central incisor began to erupt. Two years and seven months after the operation, both upper central and lateral incisors had erupted completely. In this case, the obturator was used for expectation of natural eruption of permanent incisors, space maintenance and aesthetic recovery. The permanent incisors had been able to be guided to almost correct position without traction.     

Dentigerous cyst associated with multiple mesiodens: a case report

Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. When observed with erupted and complete dentition the diagnosis is a surprise; as about 95% of dentigerous cysts involve the permanent dentition and only 5% are associated with supernumerary teeth. The usual age of clinical presentation of dentigerous cyst due to supernumerary tooth is during the first four decades. Mesiodens is a supernumerary tooth situated between the maxillary central incisors. More frequently the mesiodens occurs unilaterally, but it may also be bilateral, while three or more supernumerary teeth in the median region of the palate are more rarely found. We report a rare case of dentigerous cyst in association with multiple mesiodens in a 14-year-old female patient.     

Dentigerous cyst with an impacted canine in an unusual position-a case report

A dentigerous cyst is a type of an odontogenic cyst associated with the crown of an impacted, embedded or unerupted tooth. In this article, we report a case of dentigerous cyst with an impacted canine in an unusual position which was surgically removed.     

Keeping your eye on the ball

Dentigerous cysts develop from unerupted and impacted permanent teeth. Very rarely, supernumerary teeth are associated with dentigerous cysts and constitute about 5-6% of all dentigerous cysts. Although these cysts are not common in the first decade of life, regular thorough inspection of radiographs is of importance, as indicated by this case report. This case shows how an impacted supernumerary canine developed a dentigerous cyst, engulfing the whole of the maxillary antrum.     

Marsupialization of Dentigerous Cyst: Report of a Case

Dentigerous cyst is a common pathologic entity associated with an impacted tooth. The standard treatment for this lesion is enucleation and extraction of the involved tooth. Marsupialization of dentigerous cyst has also been advocated, once in many cases it can maintain the impacted tooth in its cavity and promotes its eruption. This report describes a case of a 13-year-old girl with a large dentigerous cyst associated with mandibular right second molar. The cyst was marsupialized and the patient was checked weekly. Two months after the surgical procedure the impacted tooth was completely erupted without orthodontic traction and therapy.     

Calcifying cystic odontogenic tumor associated with other lesions: case report with cone-beam computed tomography findings

The calcifying cystic odontogenic tumor (CCOT) simultaneously occurring with other lesions at different locations in the same patient is rare. We report a patient with CCOT associated with an odontoma, a supernumerary tooth, and a dentigerous cyst simultaneously occurring in the maxilla. Cone-beam computed tomography (CBCT) images showed a well-defined expansile lesion with internal calcification, high-density masses surrounded by low-density area, and a supernumerary tooth at the anterior maxilla. Posterolaterally to these lesions, an embedded canine with pericoronal radiolucency was detected. Histopathologic examination revealed a CCOT associated with an odontoma, a supernumerary tooth, and a dentigerous cyst of the embedded canine. Enucleation was performed, and a 2-year postoperative follow-up was uneventful. CBCT was useful in giving the differential diagnosis by depicting internal calcification of CCOT, and in revealing the extent and complex relationship of these lesions.     

Dentigerous cyst associated with multiple complex composite odontomas

Odontomas are considered to be hamartomatous malformations rather than true neoplasms. This most common odontogenic lesion results from the growth of completely differentiated epithelial and mesenchymal cells that give rise to ameloblasts and odontoblasts. Dentigerous cyst is an epithelium-lined sac enclosing the crown of an unerupted tooth. Apparently, the dentigerous cyst arises by the accumulation of fluid between reduced enamel epithelium and the tooth crown. Occasionally it is associated with supernumerary tooth or odontoma. We report a case of dentigerous cyst associated with complex composite odontoma and an impacted lateral incisor in a 30-year-old male patient.     

Inferior alveolar nerve paresthesia caused by a dentigerous cyst associated with three teeth

The dentigerous cyst is a common pathologic entity associated with an impacted tooth, usually third molars. They generally are asymptomatic, being found on routine dental radiographic examination. This report describes the case of a 43 year old male with a large dentigerous cyst associated with mandibular canine, first and second premolar teeth that caused paresthesia of the inferior alveolar nerve.     

A well-defined coronal radiolucent area involving an impacted third molar

The dentigerous cyst is the most common developmental odontogenic cyst and appears as an asymptomatic, well-defined radiolucent area surrounding the crown of an impacted tooth. Because of potential serious complications, lesions that are consistent radiographically with a dentigerous cyst should be totally removed and examined microscopically to establish a definitive diagnosis.     

Dentigerous cyst containing multiple impacted teeth: a rare case report

The dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. It is one of the most prevalent types of odontogenic cysts associated with erupted, developing, or impacted tooth, particularly the mandibular third molars, the other teeth that are commonly affected are maxillary canines. The present case report is unique as it enclosed three permanent maxillary teeth: the central incisor, lateral incisor, and canine that had to be extracted during surgical enucleation of the cyst.     

Odontogenic carcinoma occurring in a dentigerous cyst: case report and clinical management

This case report describes an unusual odontogenic carcinoma, which was detected during routine periodontal examination. The lesion occurred in a dentigerous cyst associated with an impacted third molar in an otherwise asymptomatic 66-year-old male patient. The impacted tooth and lesion were excised based on evidence of radiographic change and clinical findings. An unusual histopathologic presentation is reported. The treatment provided for this tumor and the management of impacted teeth is reviewed.     

Fusion of a third molar to a supernumerary tooth with an associated dentigerous cyst

During a routine oral examination of a 19 year-old Black male, a bony impaction of his mandibular left third molar fused to an inverted supernumerary tooth with a cystic cavity was found. Histologic examination confirmed the presence of a dentigerous cyst.     

Trauma‐induced dentigerous cyst involving an inverted impacted mesiodens: case report

Abstract – There have been only a small number of studies on the association of dentigerous cysts with supernumerary teeth. The purpose of this article was to report the case of a dentigerous cyst associated with an impacted inverted mesiodens that developed secondary to trauma to its predecessor, a non‐vital permanent maxillary central incisor. As a consequence of trauma, the central incisor’s root development was prematurely arrested and the open apex lay close to the follicle of the underlying inverted mesiodens. The negligent attitude of both the child and parent in seeking dental treatment was a contributing factor. The case was further complicated by impaction of the adjacent permanent central incisor due to the presence of another unerupted but normally oriented mesiodens. Occlusal and Intraoral periapical radiographs revealed a well‐defined radiolucent area surrounding the inverted mesiodens. Microscopic examination revealed a cystic cavity that was lined by 2–3 cell thick non‐keratinized stratified squamous epithelium resembling reduced enamel epithelium. Dentigerous cysts associated with impacted permanent teeth are not uncommon but the cysts which are induced by trauma are uncommon. Development of trauma‐induced dentigerous cyst around an inverted impacted mesiodens associated with the periapical area of a traumatized, non‐vital, immature permanent central incisor is a rare occurrence.     

Pathologic change in soft tissues associated with radiographically 'normal' third molar impactions.

Our aim was to evaluate the incidence of histological abnormalities in soft tissues surrounding impacted third molar teeth when there were no pathological conditions apparent on the corresponding radiographs. Ninety-six dental follicles were collected from third molar teeth of 63 patients. No tooth had a follicular space greater than 2.4 mm as measured on the panoramic radiograph. Specimens were examined by each of three oral pathologists, and only those independently diagnosed as cystic by all three pathologists were considered diseased. A diagnosis of dentigerous cyst was made in 31 cases; 22 of 60 mandibular specimens (37%) and nine of 36 maxillary specimens (25%) were affected. No disease other than dentigerous cyst was seen. We conclude that the incidence of dentigerous cyst associated with impacted third molar teeth is higher than reported in radiographic studies alone. The importance of histological diagnosis of dentigerous cyst should be evaluated further in the light of this unexpectedly high incidence of microscopic disease.     

Multidisciplinary management of impacted central incisors due to supernumerary teeth and an associated dentigerous cyst

Supernumerary teeth are the most common developmental dental anomaly resulting from hyperactivity of dental lamina, dichotomy, environmental factor, or polygenetic process of atavism. Supernumerary teeth present classical oral complication such as impaction of adjacent teeth, crowding, diastema formation, rotation, displacement of teeth, and occlusal interference. A dentigerous cyst associated with anterior supernumerary teeth (mesiodens) is rare and accounts for 5% of all dentigerous cysts. The present case reports describe the successful management of the impacted permanent maxillary central incisor positioned high in the vestibule. A combination of surgical and orthodontic techniques was employed to improve treatment outcome with greater hard and soft tissue preservation and to prevent psychological problems. In the surgical phase, supernumerary teeth and dentigerous cyst were removed. Subsequently traction was employed by bonding bracket on the labial surface using closed and open eruption techniques. Successively, fixed orthodontic treatment was started to align permanent maxillary central incisors in an occlusal plane. Thus, combination of surgical and orthodontic method can be the treatment of choice over surgical extraction, implant placement, and surgical repositioning.     

Small Central Odontogenic Fibroma Mimicking Hyperplastic Dental Follicle and Dentigerous Cyst

Central odontogenic fibroma has been defined as a benign odontogenic tumor, representing the intraosseous counterpart of a peripheral odontogenic fibroma. The odontogenic fibroma is a rare tumor. Differential diagnosis of radiolucent lesions in the molar-premolar region of mandible which involve impacted tooth may include central odontogenic fibroma, hyperplastic dental follicle, dentigerous cyst, unicystic ameloblastoma, and keratocystic odontogenic tumor. We describe an example of a small central odontogenic fibroma mimicking hyperplastic dental follicle and dentigerous cyst, resulting in uneruption of a primary tooth.     

A conservative approach in the management of inflammatory dentigerous cyst in transitional dentition: a case report

Dentigerous cysts are benign odontogenic cysts that develop from the reduced enamel epithelium related to the crown of an unerupted and/or impacted tooth. Inflammatory dentigerous cyst is a variety of dentigerous cyst that is mostly found in the mixed dentition, and the treatment modalities range from enucleation to marsupialization. By extracting the infected primary teeth, opening the cyst, and ensuring continuous drainage, spontaneous eruption of the involved permanent teeth occurs into the dental arch even if they are severely dislocated. The purpose of this report is to describe the successful treatment of a large dentigerous cyst by conservative surgical management.     

Orthodontic assisted tooth eruption in a dentigerous cyst: a case report

In an orthodontic practice, it is common to deal with impacted teeth, which are one of the most difficult situations dealt with by dentists. This case report describes the surgical and orthodontic management of the impacted teeth in a large dentigerous cyst. In the initial stage of treatment, the cyst was marsupialized over 7 months. After decompression of the cyst, spontaneous eruptions of the impacted tooth were noticed. Then, they were orthodontically brought into the proper occlusion.
