Management of a fused central incisor in association with a macrodont lateral incisor: a case report.
Fusion is developmental anomaly of the dental hard tissue and is defined as the joining of 2 developing tooth germs resulting in a single large tooth structure. Different treatment methods can be used according to the requirements of the situation. The purpose of this case report was to present the multidisciplinary treatment of a patient who had a permanent maxillary left central tooth fused with a supernumerary incisor and a macrodont permanent maxillary right lateral incisor. In the radiographic evaluation, it was determined that the fused tooth had 2 separate roots. The supernumerary tooth was extracted after hemisection, and endodontic treatment was performed on the remaining portion. The distal side of the macrodont lateral incisor was recontoured, and the right central incisor was reshaped with a strip crown to provide aesthetic appearance and to gain space for the alignment of teeth. Following the restoration of the incisors, orthodontic treatment was provided.

Bilateral maxillary and mandibular fourth molars. Report of a case.
Fourth molar do not occur very frequently. They tend to be unerupted or if they erupt may cause malalignment of the dentition or aesthetic problems. The preferred location is in the maxilla, and they may be normal or rudimentary and located either directly distal or distolingually to the maxillary third molar. Supernumerary molars should probably be extracted only when their presence is responsible for the failure of eruption or malalignment of permanent teeth.

Supernumerary teeth and mental retardation: the importance of early surgical intervention.
AIM: This paper reported a rare case of hyperdontia in a child of 10 years who revealed a mixed dentition and a light mental retardation. MATERIALS AND METHODS: The therapeutic approach has been based on interdisciplinary cooperation between the pediatric dentist, orthodontist and oral surgeon. TC-Dentascan, with a panoramic and occlusal radiographs revealed the presence of two supernumerary teeth in the premaxillary region and clinical examination showed an abnormality of dentoalveolar complex. Both impacted supernumerary teeth were extracted under general anesthesia. Clinical examination revealed that they appeared two premolars in shape with fully formed crowns and partly formed roots. RESULTS: Three months after the extraction of supernumerary teeth there was a spontaneous eruption of permanent central incisors and left lateral incisor. CONCLUSION: The authors emphasized the importance of removal of supernumerary teeth to eliminate the cause of a delayed eruption of permanent teeth.

Unerupted maxillary anterior supernumerary teeth: report of 204 cases.
Two hundred and four cases of unerupted maxillary anterior supernumerary teeth were found among Hong Kong school children between the ages of six to 9.5 years. The anomaly was prominent in the male with a sex ratio of 5.4:1. There was no significant difference in the distribution of unilateral and bilateral supernumerary teeth, between the two sexes. Most of the supernumeraries were located within the central incisor region. The inverted type was found to be associated with bodily displacement, median diastema and torsiversion, while the normally oriented ones were related to delayed eruption. The association of maxillary anterior supernumeraries with clinical symptoms was compared with studies on Caucasian populations, and guidelines were described for their early diagnosis.

Radiographic examination of mesiodens and their associated complications.
OBJECTIVES: To examine mesiodens with regard to their status, their influence on adjacent teeth and their alteration during the follow-up period. METHODS: From retrospective reviews of all patients who visited our institution from 1990-2001, we identified 200 patients (256 mesiodentes) who were shown to have mesiodentes on the basis of a periapical radiograph, a panoramic radiograph or an axial radiograph. RESULTS: The number of supernumerary teeth was one in 146 cases (73%), two in 52 cases (26%) and three in 2 cases (1%). Of 256 mesiodentes, the direction of the crown of the mesiodens was inverted in 172 (67%), in a normal direction in 69 (27%) and in a horizontal direction with regard to the tooth axis in 15 (6%). Of the 147 mesiodentes for which axial radiography was performed, 131 (89%) were located at a palatal site against the dental arch, 16 (11%) overlapped the dental arch and none were at a labial site. Of our 200 cases, a delay of eruption of the permanent central incisor was seen in 12 (6%), malposition or rotation of the central incisor in 5 (2.5%) and dentigerous cyst formation arising from mesiodens in 22 (11%). Marked movement of the mesiodens was seen in 10 cases during the follow-up period of 5-7 years. Some complication arising from mesiodens was seen in 19.5% of all cases in our research. CONCLUSION: Although mesiodentes are not caused by malocclusion, they may cause it. A long period of impaction of mesiodentes may bring about dentigerous cyst formation or movement of the mesiodentes.

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.

Multiple supernumerary premolars: their occurrence in three patients.
The occurrence of supernumerary teeth in the premolar regions of three patients is reported. Of the 20 supernumerary teeth identified, 16 had crowns which resembled premolars and may thus be considered to be supplemental premolars, while the remainder were conical in shape. The delayed development of the supernumerary teeth in the premolar region supports the hypothesis that these teeth were part of a post-permanent dentition. The eruption of six of the eight supernumerary teeth in the 30-year-old patient demonstrated that given time some of these teeth can erupt into the dental arch.

Case report: twin supernumerary maxillary central incisors, unerupted maxillary central incisors. Early orthodontic treatment in ten-year-old child.
This is the case report of a 10 year-old female Caucasian with a mixed dentition Class I right and Class II left side malocclusion and unerupted maxillary central incisors. It was necessary for the oral surgeon to remove twin supernumerary mesiodens prior to the placement of orthodontic appliances. Space was created to accommodate the customary, also unerupted central incisors, which were rotated 90 degrees to the midline.

Study of the frequency and the features of supranumerary teeth found in one Portuguese population.
The present study was performed on a population of subjects assisted at the dental clinic of Instituto Superior de Ciências da Saúde-Norte. The aims of the study were: (1) to analyse the prevalence of supernumerary teeth, (2) to characterise its gender distribution, and (3) to investigate the repercussions of supernumerary teeth over neighbouring teeth and tissues. From the records of all the patients received from 1993 to 2000, 16771 clinical files contained panoramic X-ray plates (8712 females and 8059 males) and were selected. A total of 151 supernumerary teeth were found in 127 patients (72 males and 55 females, aged from 5 to 63 years), corresponding to a prevalence of 0.76%. Other designed important issues were one supernumerary teeth for individual; the mesiodens type (followed by the 4th molar); conical morphology; the maxilla (namely on the maxillary medial line): location as predominant findings. Evolutionary state, 47 (31.1%) were erupted and 104 (68.9%) unerupted. In most cases 108 (71.5%), the radiological images didn't suggest alterations on adjacent teeth and/or tissues. The repercussions found, potentially associated to supernumerary teeth were: 12 (7.9%) displacement of adjacent teeth, nine (6%) delayed eruption of permanent teeth, and eight cases (5.3%) diastema formation.
