1/138. Treatment of an impacted dilacerated maxillary central incisor.Impacted incisor With Dilaceration refers to a dental deformity characterized by an angulation between crown and root causing noneruption of the incisor. Surgical extraction used to be the first choice in treating the severely dilacerated incisor. In this article, a horizontally impacted and dilacerated maxillary central incisor was diagnosed radiographically. By combining two stages of the crown exposure surgery with light force orthodontic traction, the impacted dilacerated incisor was successfully moved into proper position. However, long-term monitoring of the stability and periodontal health is critical after orthodontic traction.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |

3/138. Radiographic localization of unerupted maxillary anterior teeth using the vertical tube shift technique: the history and application of the method with some case reports.The preferred means of radiographic localization is the parallax method introduced by Clark in 1910. He used 2 periapical radiographs and shifted the tube in the horizontal plane. In 1952, Richards appreciated that a vertical tube shift could also be carried out. No major changes then occurred in the technique until Keur, in australia, in 1986 replaced the periapical radiographs with occlusal radiographs. This modification enables a greater tube movement and therefore a greater shift of the image of the impacted tooth; it also ensures that the whole of the tooth is captured on the radiograph. For the vertical tube shift, Keur introduced the use of a rotational panoramic radiograph with an occlusal radiograph. In 1987, Southall and Gravely discussed this vertical tube shift combination in the English dental literature, and it is now the preferred combination of radiographs for localizing impacted maxillary anterior teeth. Jacobs introduced this method to the American literature in 1999, but it has yet to gain acceptance in the continental European literature. Jacobs recommended, when using this combination, to routinely increase the vertical angulation for the occlusal radiograph by 10 degrees to achieve a greater image shift. Four case reports are presented in this article. Three have photographs taken at surgical exposure to illustrate how the position of the impacted tooth can be accurately predicted by appropriate interpretation of the radiographs.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
4/138. 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 = 2keywords = dental (Clic here for more details about this article) |
5/138. Immediate placement of implants in extraction sites of maxillary impacted canines.BACKGROUND: Treatment of asymptomatic impacted maxillary canines in adults is inevitable when primary canine becomes lost through extraction or exfoliation or when the impacted tooth becomes symptomatic. Treatment alternatives include an orthodontic procedure to bring the unerupted tooth to the dental arch or prosthetic replacement of the missing tooth. The authors describe an alternative treatment that involves immediate placement of implants into extraction sockets of the teeth. CASE DESCRIPTION: A patient with bilateral palatally impacted upper canines chose to have the unerupted teeth removed and replaced with implants and crowns. Two hydroxyapatite cylindrical implants were inserted through the alveolar ridge into the extraction sites. The unfilled areas in the extraction sites, around the dental implants, were packed and covered with demineralized freeze-dried bone allograft in conjunction with a collagen membrane barrier. Six months after implantation, computed tomography revealed complete osseous fill of the extraction defects and no bone loss around the implants. The implants were uncovered, and porcelain-fused-to-metal restorations were fabricated and placed. CLINICAL IMPLICATIONS: This treatment modality avoids the need for conventional preparation of teeth as part of prosthetic reconstruction or prolonged orthodontic treatment aimed at bringing the impacted canine to the dental arch. Combining the implantation with bone augmentation preserved the alveolar bone and shortened the treatment period.- - - - - - - - - - ranking = 3keywords = dental (Clic here for more details about this article) |
6/138. Second premolar serial extraction.serial extraction of mandibular second premolars should be considered if they are impacted or in cases with moderate arch length deficiency combined with an absence of dentofacial protrusion.

7/138. Compound composite odontoma in primary dentition--a case report.Compound composite odontoma, is a tumor formed by the overgrowth of transitory or complete dental tissue, made up of one or more rudimentary teeth. Although odontomes are considered to be quite common of odontogenic tumors, these rarely occur solely in primary dentition. This paper is a report of case of a compound composite odontoma, five year old child who presented to the Department of Pedodontics and preventive dentistry, College of Dental Surgery, Manipal.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
8/138. 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 = 4keywords = dental (Clic here for more details about this article) |
