BACKGROUND Dentigerous cysts associated with supernumerary teeth are rare with most of them developing around a mesiodens in the anterior maxilla. Dentigerous cysts from multiple supernumerary teeth, especially with inverted tooth, are rare in other regions of the maxilla. CASE REPORT We report a unique case of a dentigerous cyst in a child associated with multiple inverted supernumerary teet...
porary restorative systems has enabled restorative teams to deliver significantly improved aesthetic restorations. These technological advances have enhanced the clinician’s ability to optimize the aesthetic display of discolored, malaligned, or deficient tooth structure in an otherwise harmonious and intact periodontium. In the presence of anterior hard and soft tissue deformities, however, th...
Riga’s papilloma or Cardarelli's apthae describes ulceration on the ventral of the tongue in neonates and infants. It is often associated with natal or neonatal teeth. It may rarely occur in older infants. Failure to diagnose and properly treat this lesion can result in inadequate nutrient intake for the infant. Treatment should begin conservatively and should focus on eliminating the source of...
Occasionally, an orthodontic patient will accidentally traumatize a maxillary anterior tooth before or during orthodontic treatment. In some situations, the trauma will be substantial and avulse the tooth. In other accidents, the tooth may not avulse, but the pulp becomes nonvital. If the pulp is devitalized, and the root has not fully formed, the apex of the root canal may be wide. In this sit...
This paper describes an appliance to replace prematurely lost maxillary anterior teeth. A review of the literature is given. The prosthesis is different from previous appliances in its use of intraorally placed composite-filled celluloid crown forms. This allows for superior control of both esthetics and functional occlusal relationships. A case presentation is given describing laboratory and o...
The purpose of this study was to determine the possible effect of genetic factors on Bolton tooth-size discrepancy. Subjects who applied for orthodontic treatment and their siblings (106 females and 78 males) were included in the study. The ages of the subjects ranged from 13 to 21 years. The siblings were grouped according to gender: male-male (24 pairs), female-female (38 pairs) and male-fema...
Tooth disorders in the anterior region of the maxilla are very common among patients with cleft lip, alveolar bone and palate. The authors concentrate on dental disorders, erupting problems and root development, specifying dental anomalies - especially regarding the lateral incisor, central incisor and canine. Disorders may relate to the shape of the tooth, its location, size, number and they c...
UNLABELLED Coronal fractures of the anterior teeth are a common form of dental trauma that mainly affects children and adolescents. One of the options for managing coronal tooth fractures when the tooth fragment is available and there is no or minimal violation of the biological width is the reattachment of the dental fragment. Reattachment of fractured tooth fragments can provide good and long...
Ellis-van Creveld (EVC) syndrome is an autosomal recessive chondrodysplasia. The affected individuals bear a series of skeleton defects, congenital heart septum anomalies, midfacial and dental defects. Previous studies using Evc or Evc2 mutant mice have characterized the pathological mechanism leading to various types Some patients with EVC supernumerary tooth; however, it not known yet if ther...
