The authors describe a patient, aged 10 years 9 months, in whom a mandibular supernumerary premolar developed late and was not diagnosed properly because of the lack of a thorough radiographic examination.
Supernumerary molars are a rather uncommon anomaly. It is more frequent in the upper than in the lower maxillary. Its pathology is often subdued and as a general rule it is detected by X-Ray. In our opinion, its setting shows two processes: --either an extra growth; it is then a normal tooth similar in shape to the wisdom tooth; --or an evagination of the external epithelial sheath giving way to a cone-shaped laterally set tooth.
This paper describes a rare case of bilateral completely erupted supernumerary teeth found in the incisor region of the mandible of a 19-year-old Japanese female.
The endodontic treatment and aesthetic restoration of a case of Oehlers Type I dens invaginatus in supernumerary teeth is presented.
The dental, radiological, genetic and dermatoglyphic findings of an additional patient with taurodontism in association with supernumerary teeth were presented and the findings of the patient were compared with those in the literature.
Supernumerary teeth is a well-recognized clinical phenomenon. Multiple supernumerary teeth are commonly associated with variable syndromes. However the multiple supernumerary teeth reported in mandibular and maxilla premolar region of an 14-year-old female patient without any associated systemic condition/syndrome is a rare case. A review of the literature relating to supernumerary teeth is presented including possible presentations, diagnostic features and treatment options.
Two unusual cases of maleruption of mandibular third molars associated with the retention of adjacent teeth and the presence of supernumerary teeth, respectively, are described. Due to the position of the crowns to each other, this phenomenon is termed "kissing teeth" in our clinic.
To evaluate possible change of position of unerupted supernumerary teeth in the premaxilla, thirty-one patients were followed clinically and radiographically. Alteration in position could be observed in fourteen cases. Occasionally, migration of supernumerary teeth may occur if surgical intervention is postponed, resulting in a more accessible position.
The aim of the present study was to investigate putative relationships between different malocclusions such as Class III and Class II division 1, and congenital tooth anomalies. Two-hundred Class III and 215 Class II division 1 patients were examined for the presence of any of the following congenital tooth anomalies: maxillary incisor hypodontia, maxillary canine impaction, transpositions, supernumerary teeth, and tooth agenesis. Their occurrence rates were then calculated as a percentage of the total sample and were compared for statistical differences. The results revealed no statistical difference (P > 0.05) in the occurrence rates of upper lateral incisor agenesis, peg-shaped laterals, impacted canines, or supernumerary teeth between the Class III and the Class II division 1 malocclusions. When the occurrence rate of all congenital tooth anomalies was compared between the two malocclusions, Class III subjects showed significantly higher rates (P < 0.05). Comparison with published surveys on general populations showed similar occurrence rates. It can be concluded that subjects with Class III and Class II division 1 malocclusions show patterns of congenital tooth anomalies similar to those observed in the general population. Congenital tooth anomalies may represent another criterion for the study of malocclusion, with respect to their origin and development.
AIM: To determine the prevalence of concomitant developmental dental anomalies in a group of Chinese children with dens evaginatus. METHODS: The dental records and orthopantomograms of 10-15 year old children and adolescents who had been diagnosed with dens evaginatus in a school dental clinic were reviewed retrospectively. RESULTS: Four hundred and forty-eight of 7102 (6.3%) children were found to have dens evaginatus. Concomitant developmental dental anomalies were found in 77 children (17.2%). The most commonly seen dental anomalies in the study population were hypodontia, hyperdontia, microdontic maxillary lateral incisor, and dental impaction. The prevalence of these anomalies did not differ significantly to that found in the general Chinese population. When analysed separately, however, the prevalence of supernumerary premolars was found to be higher in children with dens evaginatus than in the general population, and the difference was statistically significant (P < 0.01). CONCLUSION: Supernumerary premolars appeared to be more prevalent in Chinese children with dens evaginatus than in the general population. There may be an association of supernumerary premolars with dens evaginatus in this study population.
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.
This study aims at elucidating a little known pathology. In the first instance, distinction is made between extra teeth, supernumerary teeth and mesiodens teeth. The report also covers treatment of this affliction, often imposed on the practitioner by orthodontic complications or infections caused by lesions.
A case of oblique facial cleft with supernumerary deciduous molars, probably caused by amniotic bands is reported. Besides facial cleft, and cleft palate and lip, there are sulci on the left side of the face and on the left posterior alveolar ridge. The sulci may be impressions of amniotic bands at a late gestational age and supernumerary teeth may also be related to these amniotic bands.
Dysostosis cleido-cranialis is mainly characterized by a pathognomonic deformity of the skull, a hypoplastic midface, lack of eruption of permanent teeth, supernumerary teeth, defects in the clavicles, short stature and multiple other skeletal deformities. The inheritance is autosomal dominant, but there is a considerable number of new mutations.
Two cases of bilateral double dens invaginatus in the maxillary incisor region have been reported. One of the patients (Case 1), a 12-year-old boy, had double invaginations in both of the erupted teeth in the maxillary lateral incisor region. The other patient (Case 2), a boy 8 years of age, had double invaginations in each of the two partially developed supernumerary teeth that were impacted in the palate in the maxillary central incisor region. Double bilateral dens invaginatus would appear to be a most unusual occurrence.
Thorough X-ray examination is a valuable adjunct in the clinical assessment of supernumerary teeth. Three cases of supernumerary teeth comprising paramolars and molars are presented with radiographic documentation. All the patients received surgical treatment after full clinical and radiographic evaluation.
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.
A review of the literature on supernumerary teeth in general and supernumerary molars in particular was carried out on prevalence, aetiology, complications and the treatment of supernumerary teeth. Additional teeth are relatively common and are usually of simple conical shape (supernumerary teeth) but may resemble teeth of the normal size and shape. The aim of this review is to provide reference material for dental practitioners in Zimbabwe.
