Mesiodens in the primary dentition--a case report

Supernumerary teeth are among the most significant dental anomalies affecting the primary and the permanent dentitions. Mesiodens is a supernumerary tooth with a cone shaped crown and a short root. Though it occurs frequently in the permanent dentition, it is extremely rare in the primary dentition. The exact etiology is still obscure and not well understood. Supernumerary teeth occur as isolated dental findings or as part of a syndrome. The frequency with which supernumerary teeth occur and the effects they have on development of normal occlusion justify the radiographic examination of preschool children. Early removal of such teeth is recommended if they impede the eruption of adjacent permanent teeth, appear inverted or rudimentary, associated with certain pathologic conditions or are symptomatic.     

Non-syndromic multiple supernumerary teeth transmitted as an autosomal dominant trait

Supernumerary teeth are common in the general population and occur more frequently in-patients with family history of such teeth. Multiple supernumerary teeth are associated with cleidocranial dyplasia and Gardner syndrome. However it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. We describe the occurrence of multiple supernumerary teeth in a family occurring as a non-syndromal trait. The autosomal dominant transmission of non-syndromal multiple supernumerary teeth is new.     

Radiographic diagnosis of supernumerary teeth: report of six unusual cases

The purpose of this report was to describe the radiographic findings of 6 uncommon situations of supernumerary teeth in a Brazilian pediatric dentistry and orthodontic clinic. Six cases of supernumerary teeth were diagnosed in association with other dental anomalies such as number, position, and form. The supernumeraries were asymptomatic and were detected through routine radiographic examination. The importance of routine radiographic examination is emphasized for the correct diagnosis of supernumerary teeth, and avoidance of associated complications.     

Supernumerary teeth: a case report

Supernumerary teeth are the teeth present in addition to the normal set of teeth. They may be single, multiple, unilateral or bilateral erupted or unerupted and in one or both jaws. Multiple supernumerary teeth are rare in individuals with no other associated diseases or syndromes. Our case presents with 12 supernumerary teeth in permanent dentition, of which six were erupted and six unerupted and a history of extraction of three teeth with no associated syndrome.     

A rare case of hereditary multiple impacted normal and supernumerary teeth

An eight-year-old girl residing in Bangalore presented with a complaint of retained primary maxillary and mandibular incisors. Radiographic examination of the case revealed multiple impacted permanent succedaneous teeth with deficient resorption of primary teeth and multiple impacted supernumerary teeth. Family history revealed that the mother also exhibited multiple impacted supernumerary teeth. Based on the clinical presentation, radiographic examination and histopathological studies, this paper discusses the differential diagnosis and management of such a case.     

Nonsyndromic multiple hyperdontia in a series of 13 patients: epidemiologic and clinical considerations

BackgroundThe authors conducted a retrospective-casuistic study to determine the prevalence of nonsyndromic multiple hyperdontia in a sample of the population of Madrid, as well as possible complications associated with the presence of such supernumerary teeth.MethodsThe study included a data assessment of all patients seeking dental care at a hospital's department of oral surgery across four years. The authors studied data from patients who had nonsyndromic multiple hyperdontia. We used univariate and bivariate analysis to make comparisions between variables.ResultsThe authors identified nonsyndromic multiple hyperdontia in the records of 13 patients (0.1 percent) of the total population studied. These patients had 55 supernumerary teeth. Premolars were the most frequently seen type of supernumerary tooth and constituted 45.5 percent of the sample.ConclusionsNonsyndromic multiple hyperdontia usually is diagnosed as a coincidental radiographic finding in the course of routine examination rather than as the result of an associated disease. However, the authors found a higher percentage of comorbidity than they initially expected; mechanical or obstructive pathology was associated with 20.0 percent of the supernumerary teeth and enlargement of the follicular sac of more than 3 millimeters was present in 23.6 percent of the sample.Clinical ImplicationsThe early diagnosis and follow-up of patients with multiple supernumerary teeth should help clinicians prevent the diseases associated with this kind of hyperodontia.     

Radiographic diagnosis of supernumerary premolars: case reviews

The literature reported prevalence of supernumerary teeth within the mandible and maxilla varies from 0.2-0.9%. This study reviews the formation and diverse clinical appearances of supernumerary premolars. We present case reports where supernumerary teeth were recognized as incidental findings during routine radiographic examination in patients with an age range of five to thirty-nine years. Cases are presented to illustrate that the initiation and development of supernumerary premolars are often delayed by a magnitude of years. Periodic examination is recommended for occurrence and clinical behavior. In the presented cases, displacement and resorption of the adjacent teeth was not evidenced. None of the supernumerary teeth demonstrated cystic transformation. The importance of differential radiographic diagnosis is discussed.     

Non-syndrome multiple supplemental supernumerary teeth

Multiple supernumerary teeth without any associated systemic conditions or syndromes are not common. We document a case of non-syndrome multiple supplemental supernumerary teeth in mandibular premolar region of an adolescent male patient, an incidental findings during routine radiographic examination. Periodic examination is recommended to monitor the clinical behavior.     

Non-syndrome multiple supernumerary teeth: A case report

AIM: The purpose of this case report is to present a case of a non-syndrome male patient with multiple supplemental supernumerary teeth in three quadrants of his mouth. BACKGROUND: Supernumerary teeth are described as the teeth formed in excess of the number found in a normal dentition. Prevalence of supernumerary teeth varies between 0.1% and 3.8% in the general Caucasian population. Multiple supernumerary teeth are not a common occurrence, although a single or a few supernumerary tooth/teeth in each case have been widely reported in the literature. REPORT: An 11-year-old male presented for a routine preventive dental visit. A routine panoramic radiograph showed the presence of multiple supernumerary teeth which were located in the maxillary right canine incisor region, the maxillary left premolar region, and the mandibular right premolar region. The family's medical history was non-contributory, and an extraoral examination did not reveal any abnormality. SUMMARY: It is rare to find multiple supernumerary teeth in individuals with no other associated diseases or syndromes. This case report presents a case of a non-syndrome male patient with multiple supplemental supernumerary teeth in three quadrants of his mouth.     

Multiple supernumerary teeth without any associated systemic condition or syndrome: a case report

A 49-year-old Black African male, originally of Nigerian origin, was referred by his dentist regarding a bad taste in the mouth. He was seen in a general restorative clinic at Barts and the London NHS Trust. Clinical examination did not reveal any relevant abnormalities. A panoramic tomography, however, showed the presence of multiple supernumerary teeth, which were located in the maxillary right and left premolar and molar regions, and the mandibular left premolar region. The family's history was non-contributory. The patient was unaware of the supernumerary teeth and, as far as he knew, there were no other members of his family with a similar problem. Clinical Relevance: A decision regarding the appropriate management of supernumerary teeth should be considered carefully since surgical removal of the teeth may cause damage to adjacent structures, including bone. In this respect, it is interesting and rare to find multiple supernumerary teeth in individuals with no other associated diseases or syndromes elucidated by clinical and historical enquiry.     

Familial occurrence of nonsyndromal multiple supernumerary teeth. A rare condition

The occurrence of multiple supernumerary teeth is a rare phenomenon and is often found in association with syndromes such as cleidocranial dysplasia, Gardners syndrome, or cleft lip and palate. Only a few examples of nonsyndromal multiple supernumerary teeth have been reported in the literature. There is a predilection for the mandible and in the premolar area followed by the molar and anterior regions. This article reports the presence of nonsyndromal multiple supernumerary teeth involving both jaws in children and in their mothers. The clinical and radiographic appearance of the anomalies and treatment modalities are discussed.     

Indications for surgical removal of supernumerary teeth in the premaxilla

Usually supernumerary teeth in the maxilla are removed surgically, often due to retention of the permanent teeth in the region, but in certain cases the supernumerary teeth do not cause alterations in the eruption, position or integrity of the permanent dentition. This study was performed in order to review the indications for such surgical removal. The patient records of 208 patients with supernumerary teeth during the period of 1970-81 were reviewed retrospectively. Of these patients, 52 non-operated were furthermore examined clinically and radiographically in 1982; mean observation time 7.3 years (1-22 years). Results showed that none of the 52 non-operated patients had any symptoms or pathologic conditions related to the supernumerary teeth. In 37%, progressive resorption of the supernumerary teeth was seen, and in 24% the pericoronary space was markedly reduced compared to the first examination. The position and morphology was found to have influence on the prevalence of retention of the permanent incisors (p less than 0.0001). Widening of the pericoronary space during the observation period of the non-operated patients was not seen in any of the cases. Of the total of 262 teeth, 2 well-defined pericoronary cyst (pericoronary space greater than or equal to 5 mm) were found. From the present study, it is concluded that supernumerary teeth in the premaxilla may cause pathological conditions. However, each case must be considered individually concerning surgical treatment, and if no retention of permanent teeth or pathological conditions are present, observation with regularly radiographic controls is advisable. Enlarged pericoronary space (1-3 mm) does not alone seem to indicate surgical treatment.     

Multiple supernumerary teeth and odontoma in the maxilla: A case report

Most supernumerary impacted teeth are located in the anterior maxillary region. They are classified according to their form and location. Their presence may give rise to a variety of clinical problems. The detection of supernumerary teeth is best achieved by thorough clinical and radiographic examination. Their management should form part of a comprehensive treatment plan. This article presents an overview of the diagnostic problems associated with multiple supernumerary impacted teeth and includes a discussion of the classification, diagnosis, and management of this difficult clinical entity.

A case of eruption guidance for eruption disturbances of the bilateral second molars caused by supernumerary teeth

We report a rare case of eruption disturbance of the bilateral second molars caused by supernumerary teeth in a 7-year-old Japanese boy. The supernumerary teeth were detected by radiographic examination. Computed tomography (CT) was used to examine the positional relationship of the supernumerary teeth and neighboring second molars. CT images showed conical-shaped supernumerary teeth on the upper buccal side of the unerupted mandibular second molars. The cusps of the supernumerary teeth pointed toward the lingual side. Because the two supernumerary teeth threatened to disturb the eruption of the second molars, they were surgically removed at 2 years and 4 months after diagnosis. After removal of the supernumerary teeth, the mandibular second molars erupted at a normal age and aligned normally within the dentition. To the best of our knowledge, this is only one case report of eruption guidance for eruption disturbances of the bilateral second molars caused by supernumerary teeth.     

Supernumerary teeth in the primary dentition: a report of two cases

Supernumerary teeth occur frequently in the permanent dentition, but they are rare in the primary dentition. Mesiodens is a supernumerary tooth with a cone shaped crown and a short root. The supernumerary tooth which bears resemblance to the tooth with which it is associated is called a supplemental tooth. The etiology of supernumerary teeth is still unknown and not well understood. Radiographic examination of pre-school children is essential for their diagnosis. Early removal of these teeth is required so that complications such as delay in eruption of permanent teeth, crowding, diastema, rotations and certain pathologic conditions can be averted.     

Suspected Endodontic Failure in a Patient with Cleidocranial Dysplasia: A Case Report

A patient’s medical history and related dental manifestations can significantly contribute to confounding signs and symptoms leading to a diagnostic challenge. An 18-year-old female patient presented with persistent radiographic radiolucency associated with the apex of a previously treated tooth (tooth 9); asymptomatic apical periodontitis and endodontic failure were suspected. This report presents how a patient’s condition of cleidocranial dysplasia had a profound effect on her dental history, which included the presence of multiple supernumerary teeth. Extensive surgical intervention during the patient’s childhood was required to remove the supernumerary teeth, which resulted in an endodontic misdiagnosis in her adult life. After clinical and radiographic examination, the patient was diagnosed with a periapical scar. Periapical fibrous scars have a prevalence of between 2.5% and 12% and are a rare healing process with fibrous tissue after surgical and nonsurgical interventions. This report describes the diagnosis and pathophysiology of fibrous scars, including their risk factors and long-term monitoring approaches.     

Anterior maxillary supernumerary teeth: A clinical and radiographic study

Clinical records and radiographs of 90 patients with 113 anterior maxillary supernumerary teeth (mesiodens) have been evaluated. Although uncommon, mesiodentes are the most frequent supernumerary teeth and may disturb the eruption and/or position of the adjacent permanent incisors. Clinical and radiographic examination may disclose the number, direction and location of mesiodentes and their effects on neighbouring teeth. In the present study the majority of the supernumerary teeth lay palatal to the central incisors. Complete or partial eruption of a mesiodens was rare, hence the importance of radiographs to locate supernumerary teeth in the premaxilla. Pathological findings included the formation of dentigerous cysts in three patients and complete ossification of the pericoronal space with resorption of the crown of the mesiodentes in eight cases. Retention and malposition of the adjacent permanent incisors occurred in 39 and 24 cases, respectively.     

Multiple and relapsing supernumerary teeth associated to dens invaginatus. Review of the literature and case report

The aim of this paper is to show problems related to supernumerary teeth therapy according to their formation and mineralization. The clinical case of an 11-year old boy suffering from alteration of the eruptive sequence of the upper incisor teeth caused by 2 supernumerary teeth in the premaxilla, is reported. What is interesting about this case is that after the surgical removal of the supernumerary teeth, with a radiographic examination taken 6 months later, 2 other supernumerary teeth were observed. The authors point out that while the clinical approach can be the same for different situations it is not possible to have the same approach for the surgical therapy which may be different from case to case.     

Non-syndromic multiple impacted supernumerary teeth with peripheral giant cell granuloma

Peripheral giant cell granuloma (PGCG) is a relatively frequent benign reactive lesion of the gingiva, originating from the periosteum or periodontal membrane following local irritation or chronic trauma. PGCG manifests as a red-purple nodule located in the region of the gingiva or edentulous alveolar margins. The lesion can develop at any age, although it is more common between the second and third decades of life, and shows a slight female predilection. PGCG is a soft tissue lesion that very rarely affects the underlying bone, although the latter may suffer superficial erosion. A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. These teeth may be single, multiple, erupted or unerupted and may or may not be associated with syndrome. Usually, they cause one or the other problem in eruption or alignment of teeth, but may also present without disturbing the normal occlusion or eruption pattern. Management of these teeth depends on the symptoms. Presented here is a case of PGCG in relation to the lower left permanent first molar with three supernumerary teeth in the mandibular arch but no associated syndrome.
