Retrospective study of 145 supernumerary teeth.

OBJECTIVE: The goal of the present retrospective study is to describe the distribution of the supernumerary teeth in a population of patients that have been attended at the Public Clinic of the Department of Oral Surgery. BACKGROUND: Supernumerary teeth and multiple hyperdontia are usually associated with different syndromes, such as Gardner syndrome, or with facial fissures; however, they can appear in patients without any pathology. Their prevalence oscillates to 0.5-3.8% in patients with permanent teeth and to 0.35-0.6% in patients with primary teeth. PATIENTS AND METHODS: A total of 36,057 clinical histories of patients that were admitted at the clinic between September of 1991 and March of 2003 were revised. The following data were extrapolated: age, sex, number of extracted supernumerary teeth, localization, morphology and type of supernumerary teeth. Consequently, 102 patients were included into the present study. RESULTS: Of the 147 supernumerary teeth identified in the oral cavities of patients 145 were extracted. The most frequent supernumerary teeth identified were mesiodens (46.9%), followed by premolars (24.1%) and fourth molars or distal molars (18%). As for location, 74.5% of the supernumerary teeth were found in the superior maxillary bone and 46.9% of the supernumerary teeth were present in the palatine/lingual area. Heteromorphology was found in two thirds of the supernumerary teeth, with conical shape being the most frequent. Finally, 29.7% of the supernumerary teeth had occlusion with permanent teeth, and mesiodens were the predominating type of supernumerary teeth that showed this feature. CONCLUSIONS: Mesiodens very frequently cause retention of permanent incisors, which erupt spontaneously after the extraction of supernumerary teeth, if there is sufficient space in the dental arch and if they conserve the eruptive force. Generally, supernumerary premolars are eumorphic and are casually discovered during radiological exam, if not producing any symptomology.

Fusion of mandibular third and supernumerary fourth molars.

Fusion of the permanent molars is a relatively uncommon dental anomaly. In this article, a case of fusion of a symptomatic mandibular third molar with a supernumerary fourth molar is reported. The differentiation with other forms of 'double teeth' is explained and the possibility of the initial panoramic radiograph view being misinterpreted as an artefact is discussed.

Supernumerary premolars: a literature review.

Supernumerary premolars appear to be more common than previously estimated. The purpose of this report was to review most of the cases published in the dental literature since 1932. The authors found that supernumerary premolars occur 3 times more in males than in females, indicating a possible sex-linked inheritance, with the highest frequency of occurrence in the mandibular premolar region (74%). They are also the most common supernumerary teeth in the mandibular arch (7%), and their incidence is 1% (1 in 157)-much higher than previously reported. Maxillary supernumerary premolars were found to occur at a lower rate (26%). The possible mechanisms of development are described, with a localized hyperactivity of the dental lamina being the most widely accepted theory. Recurrence of supernumerary premolars after being surgically removed has been reported in 8% of the cases reviewed. Patients with a previous history of anterior conical or tuberculated supernumerary teeth at an early age have a 24% possibility of developing single or multiple supernumerary premolars at a later age. Early diagnosis and appropriate follow-up with panoramic radiographs is extremely important. Various treatment recommendations are also discussed.

Non-syndrome multiple supernumerary teeth: literature review.

Multiple supernumerary teeth without any associated systemic conditions or syndromes are not common. The author reviewed most of the cases reported in the English-language literature from 1969 to the present. It was found that there was a predilection of non-syndrome multiple supernumerary teeth to occur in the mandible. When analyzed according to specific sites for both jaws, there was a predominance of the multiple supernumerary teeth to occur in the premolar area, followed by the molar and the anterior regions respectively. The mandibular premolar region had the highest frequency of occurrence for both jaws combined.

Completely impacted teeth in dentate and edentulous jaws.

Panoramic radiographs from 1026 patients were examined for the presence of completely impacted teeth. The prevalence of completely impacted teeth in the edentulous jaw was lower than that in the dentate jaw in both the upper and lower jaws. The prevalence of completely impacted third molars in the edentulous jaw was also lower than that in the dentate jaw. However, there was no difference in the prevalence of completely impacted canine teeth and completely impacted anterior maxillary supernumerary teeth (mesiodens) in the edentulous jaw. These findings may indicate that completely impacted canine teeth and impacted anterior maxillary supernumerary teeth (mesiodens) are not influenced by the loss of erupted teeth.

[Ten cases of supernumerary premolars and review of the literature].

In this study, the modern literature concerning the classification and the incidence of supernumerary teeth and specificly premolars, is reviewed. Extensive reference is given to the aetiology and pathogeny of the existence of supernumerary teeth and the main theories that have been stated until now are described. The diagnostic problems that may result from these are discussed, as well as the methods and ways of their early detection. The unfavourable complications, the prognosis and the treatment of supernumeraries and specificly premolars are described. Finally, the radiografic findings of 10 cases of supernumerary premolars of ours are presented. A statistical analysis concerning sex, morphology, localization, impaction and bilateral presence of supernumerary premolars, that was conducted for the set consisting of these 10 cases and 50 others, that where obtained from the literature, is also presented.

Indications of autotransplantation of teeth in orthodontic problem cases.

Autotransplantations of teeth have been widely used in orthodontics, mainly in cases of severe impactions, early loss of permanent teeth, or congenital aplasia. In specific clinical situations, indication of extractions or supernumerary teeth may provide donor teeth for transplantations avoiding prosthetic or implant therapy. Two cases are presented to illustrate the topic, and prognostic factors of autotransplantation are discussed.

Ectopic supernumerary teeth as a predisposing cause in localized periodontitis. Case report.

Supernumerary teeth are relatively common in the maxillary incisor and molar areas. However, bilateral ectopic, fully erupted supernumerary mesiodentes are relatively rare. The present case documents a patient with localized periodontitis of the maxillary first and second molars associated with bilaterally erupted supernumerary teeth located in proximity to the buccal embrasure space between the molars. Combined clinical data suggested that these ectopic mesiodentes predisposed or contributed to the development of localized periodontitis.

[Development of the dentition in cleidocranial dysplasia].

The purpose of the present investigation was to describe the formation, maturation and eruption of the dentition, including supernumerary teeth in a sample of patients with cleidocranial dysplasia. The dentition was evaluated from orthopantomograms, intraoral radiographs, cephalometric films, surgically removed teeth and intraoral photographs in 22 patients (10 men, 12 women), aged 3.5 to 34 years. Formation of primary teeth was normal, whereas all patients but one had supernumerary permanent teeth. Frequency of supernumerary teeth ranged from 22% in the maxillary incisor region to 5% in the molar regions. Anterior to the molar region supernumerary teeth were formed lingually and occlusally to the normal teeth. Maturation of the primary dentition was normal, while permanent teeth were delayed from 1 to 4 years. Supernumerary teeth were delayed about 4 years in relation to normal permanent teeth. Eruption of primary teeth was normal, whereas all patients had severe eruption problems of permanent teeth.(ABSTRACT TRUNCATED AT 250 WORDS)

Hereditary gingival fibromatosis associated with hearing loss and supernumerary teeth--a new syndrome.

Hereditary gingival fibromatosis can occur as an isolated trait or as part of a syndrome. We report on three generations of one family featuring an autosomal dominant syndrome with variable expression of gingival fibromatosis with associated hearing deficiencies, hypertelorism, and supernumerary teeth. We propose that this represents a new syndrome within the spectrum of those including gingival enlargement.

Six mandibular permanent incisors: report of a case.

This article involves dental management of a girl with bilateral supplemental mandibular permanent incisors. If not removed promptly, these supernumerary teeth will lead to crowding and malocclusion; as a result, early diagnosis is important. Dentists who treat children should be aware of this condition when unusual crowding and displacement is seen in the mandibular incisor region.
