Application of Computed Tomography for Supernumerary Teeth Location in Pediatric Dentistry

Conventional radiographs provide bi-dimensional images of three-dimensional structures limiting optimal treatment planning. To overcome this deficiency, Computed Tomography (CT) has been used as a diagnostic method in Medicine and Dentistry. CT allows for supernumerary teeth location, the establishment of positional relations with other teeth, and the assessment of surrounding bone thickness; thus, facilitating surgical access and technique choice while reducing the procedure time, of great importance in pediatric dental care. The aim of this study was to present the possibility of applying CT for supernumerary teeth location, through the case report of a five-year-old female patient presenting two supernumerary teeth in the anterior palatal area. In conclusion, CT appears to be an excellent image diagnostic method for locating unerupted supernumerary teeth, providing precise information for planning and performing the surgical approach, while reducing operatory time and post-operatory complications; factors of extreme importance when treating young children.

Multiple Impacted Teeth: Report of 3 Cases

While impaction of tooth is widespread, multiple impacted teeth by itself is a rare condition and often found in association with syndromes such as cleidocranial dysplasia or Gardner's syndrome. A light of radiographic examination, we describe three Turkish young males with multiple impacted teeth who didn't possess any systemic conditions or syndromes involving both jaws. The first patient, a 21-year-old young male, had 16 unerupted teeth and 5 unerupted supernumerary teeth. The second patient with totally edentulous mandible, a 20-year-old young male, had 31 unerupted teeth. The third patient, a 21-year-old young male, had 22 unerupted teeth and 4 unerupted supernumerary teeth. Based on the clinical presentation, radiographic examination and histopathological studies, this paper discusses the differential diagnosis and management of such cases.

Mesiodens: a radiographic study in children

We analyzed the frequency and radiological features of mesiodens in a group of children in Turkey. The study was based on a radiographic review of 23,000 pediatric patients (male: 12,667 female; 10,333) who visited the Department of Oral Diagnosis and Radiology during the period 2003-2005 (3 years). The presence of an unerupted supernumerary tooth, or tooth bud between the 2 central incisors or as unilateral or bilateral teeth in the midline of the maxilla was noted as mesiodens on radiographs. Eighty-five cases of mesiodens in 69 patients were found. Complete documentation, including radiographs, for these 69 patients were studied and analyzed. In addition to gender and age, the following information about the mesiodens was recorded: 1) number; 2) shape; 3) position; 4) complications caused by the mesiodens; 5) treatment. Of the 69 patients, the ratio of boys (47 cases) to girls (22 cases) was 2.1:1. Fifty-three (76.8%) of the children had 1 mesiodens, and 16 (23.1%) had 2 mesiodentes bilaterally to the midline. Of the 85 mesiodentes, 67 (78.8%) were fully impacted, 6 (7%) were partially erupted, and 12 (14.1%) were fully erupted. Most of the mesiodentes (55.2%) were found in the vertical position, followed by inverted position (37.6%), and horizontal position (7%). The main complications were delayed eruption of the permanent incisors (38.8%), maxillary midline diastema (17.6%), axial rotation or inclination of erupted permanent incisors (16.4%), and resorption of the adjacent teeth (4.7%) The prevelance of mesiodens has been estimated to be 0.15% to 2.2% of the population.

Cleidocranial Dysplasia: Diagnostic Criteria and Combined Treatment

Cleidocranial dysplasia (CCD) is an uncommon, generalized skeletal disorder characterized by delayed ossification of the skull, aplastic or hypoplastic clavicles, and serious, complex dental abnormalities. There are many difficulties in the early diagnosis of CCD because a majority of the craniofacial abnormalities becomes obvious only during adolescence. In the present case, a hypoplastic midface, a relative prognathia of the mandible, and close approximation of the shoulders in the anterior plane were the conspicuous extraoral findings. Prolonged exfoliation of the primary dentition, unerupted supernumerary teeth, and the irregularly and partially erupted secondary dentition produced occlusional anomalies. The presence of the second permanent molars together with the primary dentition and wide spacing in the lower incisor area were typical dental signs. Gradual extraction of the supernumerary teeth and over-retained primary teeth was the first step of oral surgery. This was followed by a surgical exposure of the unerupted teeth by thinning of the cortical bone. Orthodontic treatment was aimed at parallel growth of the jaws. Removable appliances were used to expand the narrow maxillary and mandibular arches, and a Delaire mask compensated for the lack of sagittal growth of the upper jaw. Temporary functional rehabilitation was solved by partial denture. When the jaws have been fully developed, implant insertions and bridges are the therapeutic measures. The reported case and the literature data support the importance of the early diagnosis and interdisciplinary treatment of CCD.

Dientes supernumerarios anteriores no erupcionados: Revisión de 125 casos

Introduction: Supernumerary anterior teeth are a frequent cause of alterations in the erup- tion of permanent teeth. These alterationes can be minimized if the removal of the supernumerary is done at the right moment. The objectives of this study were to evaluate alterations in permanent teeth and the influence of the age of the patient on the evolution. Material and methods: 125 pedia- tric patients who presented unerupted supernumerary anterior teeth were studied during the period 1994 - 2000. The factors analized were the patients age, characteristics of the supernumerary teeth and alterations in the eruption of permanent teeth, as well as post-surgical evolution. Results: The mean age was 9,9 years. 77% of the study population were male. In 69,6% of the cases, eruptive alte- rations in permanent teeth were seen. Of this group, after surgery, 41,4% erupted spontaneously, 11,5% erupted ectopically and 47,1% did not erupt at all. When relating the age of the patient to the failure of eruption, there was a statistically significant relationship. The patients treated before age 9, had favourable results. Conclusions: The presence of unerupted anterior supernumerary teeth is asso- ciated with eruptive alterations on permanent teeth. The age of the patient at the time of treatment influences the evolution of the permanent teeth.

Lichenoid Lesion And Oral Squamous Cell Carcinoma Of The Tongue

Supernumerary teeth have a genetic predisposition with a predilection for males. This article reports an uncommon radiological finding in a non-syndromic sibling pair who presented with supernumerary teeth of different morphologies on opposite and different regions of the dental arches. A 14-year-old Chinesemale presented with a conical supernumerary palatally placed between the upper right central and lateral incisors. His older brother had unerupted bilateralsupplemental supernumerary teeth between the roots of the lower second premolars and first permanent molars. Trends of the phenotypic presentation of familial non-syndromic supernumerary cases are discussed. Familial supernumerary teeth have been suggested to be due to autosomal dominance or recessive traits. Variation in the numeral, spatial and morphological phenotypic expressions suggests a multifactorial model of multiple genetic, epigenetic and environmental influences. Clinicians need to be mindful of the possible phenotypic variations that may present when treating cases with family history of dental anomalies.

Mandibulofacial dysostosis. Case report

A case of mandibulofacial dysostosis (Treacher Collins syndrome) is presented. Clinical features and skull radiographs revealed typical anomalies associated with the syndrome. Cleft of the soft palate and unerupted multiple supernumerary teeth were present in this case. No haematological, biochemical or immunological abnormalities could be detected in the patient. Pedigree analysis showed an autosomal dominant mode of transmission of the disease. Chromosomal studies did not reveal any structural or numerical discrepancies.

Supernumerary teeth in the premaxillary region: its effects on the eruption and occlusion of the permanent incisors

Abstract The presence of supernumerary teeth in the premaxillary region may cause a variety of pathological effects. This study was carried out to determine the various aspects of supernumerary teeth in the premaxillary region, particularly the effects of the supernumerary teeth on the permanent incisors and surrounding tissues. Approximately 20 percent of the patients (n=49) with supernumerary teeth did not present with any abnormality. A high proportion of patients (37.9 percent) had delayed or failure of eruption of permanent teeth and 24.1 percent had rotation or displacement of permanent teeth. Other effects observed were median diastema and cystic changes around the unerupted supernumerary tooth. The high proportion of pathological effects seen showed that early diagnosis of the anomaly is important to intercept damage to the adjacent normal teeth and surrounding tissues. However, no cases of root resorption of the permanent teeth due to the presence of supernumeraries were observed.

上顎正中部に生じた嚢胞の臨床病理組織学的検討

Clinical and histological characteristics of 19 cysts that occurred symmetrically in the anterior portion of the midline maxilla were studied. Radicular cysts in the incisal region were excluded because they did not fit to the above category.Twelve were non-dentigerous developmental cysts and palatal swelling was found more often than in the other group of cysts with an unerupted supernumerary tooth, and the bony defect of the palate was noted in 11 cases.Radiographically, nasopalatine duct cyst was suspected in 8 cases, but the other 4 cysts presented the features consistent with those of median palatine cyst and in one the normal structure of the incisal canal was clearly recognized in the cystic radiolucency, although the relationship was confirmed at operation. Pseudostratified ciliated columnar epithelium was the main lining element in 8 cases.Mucous cells and Goblet cells were frequently seen. Neurovascular bundles were found in 8 cases and the subepithelial blood vessels were arranged parallel to the epithelial layer.Diagnosis of nasopalatine duct cyst was suspected in all cases.The other 7 cysts were dentigerous cysts with a swelling on the labial aspect of the anterior maxilla.The lining epithelium was stratified squamous epithelium and mucous cells and neurovascular bundles were noted in 2 cases, but differential diagnosis was easy because of the presence of the crown of an unerupted tooth in the cystic cavity.The results indicate that the cyst occurring symmetrically in the anterior portion of the midline maxilla is either nasopalatine duct cyst or dentigerous cyst and the possibility of median palatine cyst or radicular cyst is comparatively low.

Interdisciplinary treatment of multiple unerupted supernumerary teeth: Report of a case

A case of multiple supernumerary teeth is presented. The dentition exhibited retained deciduous teeth, unerupted permanent teeth, and a palatally displaced maxillary canine. Cooperation of the individual practitioners of three branches of the profession is considered mandatory in all aspects of the treatment, and emphasis is placed on correct timing of treatment. Patient motivation in relation to the specific problem is also discussed.

An unusual calcification of the pulp: a case report

A case is reported in which the pulp of a traumatized central incisor was completely calcified after the surgical removal of an unerupted supernumerary tooth that was lying proximal to the apex of the central incisor.

Surgical and orthodontic management of an unerupted maxillary permanent incisor: report of case

The permanent maxillary left central incisor in a 10-year-old boy did not erupt because of the presence of an unerupted supernumerary tooth. A supernumerary tooth prevented the eruption of the permanent maxillary left central incisor. Periodic routine radiographic examinations had not been made, and diagnostic problems were complicated by the progressive calcification within the pulp chamber of the supernumerary tooth. Positioning of the permanent incisor required a year of treatment.

Cleidocranial dysostosis: Report of a case

Cleidocranial dysostosis is a rare congenital condition, characterized chiefly by skeletal structure defects. The most striking features are the large brachycephalic head with prominent frontal bosses, the presence of many unerupted supernumerary teeth, and the partial or complete absence of clavicles. The condition is familial; it can be transmitted by either parent to sons or daughters. It is congenital and is frequently but not always hereditary. The cause is unknown.
