2/16. The surgical uncovering and orthodontic positioning of unerupted maxillary canines.1. The presence of the maxillary canine is vital to the function and esthetics of the dental complex. The availability of this tooth must be carefully considered during an orthodontic diagnosis. Lack of space is the most common cause of canine impaction. Other contributing factors are that this tooth has the longest period of developmenent and that it is bigger longer, and travels farther while erupting than any other tooth. 2. Proper management of unerupted canines is a challenge to the dental practitioner. Maxillary canines are found impacted to both the buccal and the lingual. Palatal impactions are much more common than labial impactions, but, of the two, labial impactions are more difficult to manage. 3. An appropriate surgical procedure which opens to the crowns of unerupted teeth is a key to uneventful orthodontic positioning of these teeth. Packing the follicular space with baseplate gutta-percha and keeping the crown open to the oral cavity with surgical WondrPak is an effective method of making the tooth erupt into the oral cavity. 4. Modern preformed bands and improved cements make the placement of attachment on malposed teeth relatively easy. Direct bonding techniques are also of value in the management of unerupted teeth. 5. It is practical to move teeth orthodontically from seemingly impossible positions into ideal alignment. Such teeth will function normally, and no evidence will be left of their original position or of their having been moved over long distances.- - - - - - - - - - ranking = 29.054597070994keywords = oral cavity, cavity (Clic here for more details about this article) |
3/16. Hereditary sensory and autonomic neuropathy: review and a case report with dental implications.Hereditary sensory and autonomic neuropathy (HSAN) is a rare syndrome which is seen in early childhood. Five different types are described. Absence of pain and self-mutilation are characteristic findings of this syndrome. Teeth in the oral cavity can cause damage to the oral tissues and tongue. When it is diagnosed, there should be co-operation between dentist and neurologist. Using an oral shield prevents the biting and, thus, traumatization of the tissues can be prevented. A case report which is diagnosed as HSAN type 4 is presented and information submitted about its treatment.- - - - - - - - - - ranking = 14.527298535497keywords = oral cavity, cavity (Clic here for more details about this article) |
4/16. Complete intrusion of a maxillary right primary central incisor.This clinical article presents a rare presentation of complete intrusion of a maxillary right primary central incisor. Routine examination of a 29-month old female patient revealed an intrusion injury where the primary central incisor was displaced through the floor of the nasal cavity. The traumatic impaction was erroneously diagnosed as an avulsion injury by the attending emergency room physician and later discovered by the dental team during routine care. The injury was documented with radiographs. The intruded incisor was removed through the right naris utilizing general anesthesia to manage behavior and surgical access. This article emphasizes the importance of radiographs and demonstrates the need to involve the dental professional in initial assessment of dental trauma.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
5/16. Multidisciplinary evaluation and clinical management of mesiodens.Supernumerary teeth are a disorder of odontogenesis relatively common in the oral cavity and characterized by an excess number of teeth. The term mesiodens is used to refer to an unerupted supernumerary tooth in the central region of the premaxilla between the two central incisors. The complications associated with mesiodens include: lack of eruption of permanent teeth, the deviation of the eruption path, rotations, retention, root re-absorption and pulp necrosis with loss of vitality, and diastema. Early detection of mesiodens is most important if such complications are to be avoided. This report describes the treatment of a maxillary central incisor impacted by a mesiodens. The case initially required only surgical treatment, to remove the supernumerary tooth. Successively, orthodontic therapy was done to bring into position the left permanent central incisor, which erupted physiologically, but rotated 90 degrees around along its long axis.- - - - - - - - - - ranking = 14.527298535497keywords = oral cavity, cavity (Clic here for more details about this article) |
6/16. Delayed removal of a fully intruded primary incisor through the nasal cavity: a case report.Complete intrusion of a primary anterior tooth may initially be diagnosed as an avulsion injury. The importance of a correct first clinical and radiological examination of a young patient who has sustained trauma to the anterior primary teeth is stressed in this article. This issue is illustrated by a case presentation where a 3-year-old girl had a delayed treatment of 5 days after a primary incisor was fully impacted by a fall trauma into the nasal cavity. This was due to an incomprehensible clinical and radiological examination by the first examining dentist. The impacted tooth was later removed through the right nostril under general anesthesia. Two-year follow-up showed no adverse clinical or radiological problems even though eruption of the permanent successor had not taken place at that time.- - - - - - - - - - ranking = 5keywords = cavity (Clic here for more details about this article) |
7/16. Maxillary odontogenic keratocyst with respiratory epithelium: a case report.We report a case of odontogenic keratocyst with a respiratory epithelial lining and a malformed impacted tooth in the maxilla of a 39-year-old Japanese female who suffered from swelling symptoms for half a year. CT examinations revealed an air-filled cystic lesion with an impacted tooth crown in the maxillary bone which expanded to the nasal cavity as well as to the maxillary sinus. Histopathologically, the surgically removed cyst wall consisted of fibrous granulation tissue with a lining of parakeratinized squamous epithelium as well as ciliated pseudostratified epithelium and with retention of desquamated keratin materials in the lumen. The impacted tooth was malformed lacking a root portion. We discuss the frequency of respiratory epithelium in odontogenic keratocysts.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/16. Aberrant root formation: review of root genesis and three case reports.The mechanism of root formation and tooth eruption is a complex process which is not fully understood. Prior to a tooth emerging into the oral cavity, root genesis is initiated by derivatives of the enamel organ. The dental follicle mediates an eruption pathway allowing for movement of the developing tooth in a coronal direction. As the tooth moves towards the oral cavity, root formation occurs passively in the resulting space. Failure of the enamel organ and dental follicle to properly coordinate may result in complications in the eruption process. This clinical report presents 3 cases of isolated, unerupted teeth with dysmorphology of the roots. The process of root development and tooth eruption is also briefly reviewed.- - - - - - - - - - ranking = 29.054597070994keywords = oral cavity, cavity (Clic here for more details about this article) |
9/16. Recurrent calcifying odontogenic cyst involving the maxillary sinus.The calcifying odontogenic cyst is an uncommon lesion that occurs in both jaws, however involvement of the maxillary sinus is rare. The accepted mode of treatment is enucleation with curettage since it is generally believed that recurrence following such treatment is extremely rare. Of the reported cases of recurrent calcifying odontogenic cysts, none have involved the maxillary sinus. This report is of a large recurrent calcifying odontogenic cyst involving the maxillary sinus, eroding the orbital floor as well as anterior and medial walls of the maxillary sinus and displacing an impacted upper canine into the nasal cavity, in a 45-year-old male patient, 8 years after the initial enucleation.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/16. Surgical repositioning of a developing maxillary permanent central incisor in a horizontal position: spontaneous eruption and root formation.This report describes the surgical repositioning of a developing maxillary permanent central incisor in a horizontal position, followed by spontaneous eruption and root formation without orthodontic traction. Surgical exposure of the right central incisor was achieved. A 7-year-old boy referred for orthodontic consultation. Radiographic examination showed the crown of a maxillary right central incisor to be positioned horizontally with root formation at the initial stage. The surgically repositioned incisor (by a close-eruption surgical flap technique) spontaneously erupted into correct alignment after 2 years 3 months. The erupted incisor remained vital and responded normally to percussion, mobility and sensitivity testing. The soft tissue, periodontal attachment, gingival contour and probing depths were normal. Follow-up radiographs confirmed the continued development of the root, with revascularization of the pulp and a normal appearance of the periodontal space and lamina dura. There was, however, shorter root formation and a narrower root cavity compared with the contralateral incisor. As a result, no orthodontic traction and alignment were required. This method of surgical repositioning is a viable alternative to the traditional approach of extraction or surgical exposure followed by orthodontic traction for a developing maxillary permanent central incisor in a horizontal position.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
