Cone beam computed tomography role in diagnosis and treatment of impacted canine patient's: a case report.

Laffranchi L1, Dalessandri D, Fontana P, Visconti L, Sapelli P.Author information 1Doctoral School in Medicine and Experimental Therapy, Specialization in Physiopathology of Mastication and the Stomatognathic Apparatus, Dental Materials, XXIII cycle, Department of Biomedical Sciences and , Human Oncology, University of Turin, Turin, Italy.AbstractA tooth is impacted when its apex is formed but does not erupt as expected during the physiological timeframe of eruption. The frequency with which the upper canine is impacted in the sample examined varies from 1% to 5% of the population in the second decade of life. The most frequent causes of inclusion of the upper canine are: lack of resorption or precocious loss of the root of the deciduous, agenesis of the lateral, an anomaly in its shape, lack of space in the arch, presence of a mechanical obstacle to the eruption, and lastly due to hereditary factors. When dental impaction is suspected, radiographic examination is indicated to evaluate the effect that the impacted element is having in the context of the osseous structure and to evaluate its relationships with adjacent teeth, the presence of mechanical obstacles, the placement of the inclusion and its orientation in space, how well developed the root is, and any anomalies in its shape. In addition to the classic orthopantomography (OPT), endoral radiography, teleradiography, can be used in order to obtain three-dimensional and life-size images, techniques of computed tomography (CT). In particular, cone beam CT, obtains this type of image using a radioactive dose comparable to that obtained summarizing the classic radiographic examinations requested by an orthodontist and moreover less that that administered when using classic multi-layer spiral CT medical equipment. This case report describes the diagnostic iter and orthodontic-surgical treatment of a patient with enclosure of the right upper canine.

Unilateral posterior crossbite with mandibular shift: a review.

Kennedy DB1, Osepchook M.Author information 1drdavidkennedy@yahoo.caAbstractBased on this literature review, early orthodontic treatment of unilateral posterior crossbites with mandibular shifts is recommended. Treatment success is high if it is started early. Evidence that crossbites are not self-correcting, have some association with temporomandibular disorders and cause skeletal, dental and muscle adaptation provides further rationale for early treatment. It can be difficult to treat unilateral crossbites in adults without a combination of orthodontics and surgery. The most appropriate timing of treatment occurs when the patient is in the late deciduous or early mixed dentition stage as expansion modalities are very successful in this age group and permanent incisors are given more space as a result of the expansion. Treatment of unilateral posterior crossbites generally involves symmetric expansion of the maxillary arch, removal of selective occlusal interferences and elimination of the mandibular functional shift. The general practitioner and pediatric dentist must be able to diagnose unilateral posterior crossbites successfully and provide treatment or referral to take advantage of the benefits of early treatment.

Immunocytochemical localization of cathepsins B and G in odontoclasts of human deciduous teeth.

Sasaki T1, Ueno-Matsuda E.Author information 1Second Department of Oral Anatomy, School of Dentistry, Showa University, Tokyo, Japan.AbstractFor clarification of the mechanisms by which odontoclasts resorb deciduous teeth during physiological root resorption, cysteine-proteinases such as cathepsins B and G were immunocytochemically localized in odontoclasts at the ultrastructural level. Extracted human deciduous teeth undergoing root resorption were fixed with a mixture of formaldehyde and glutaraldehyde and processed for immunocytochemical detection of these enzymes. Sheep antisera, raised against either human cathepsin B or G, were used as primary antibodies. In odontoclasts, specific immunogold labeling of both anti-cathepsin B and G was clearly localized in lysosomes and pale vacuoles of various sizes, and in a portion of the extracellular canals of odontoclastic ruffled borders. In the presence of either antibody, the cytoplasmic matrix, mitochondria, and nuclei were minimally labeled by immunogold particles. The presence of these proteolytic enzymes in odontoclasts suggests that, during odontoclastic root resorption, these enzymes are involved in the formation of resorption lacunae by means of intra/extracellular degradation of collagen and other non-collagenous matrix proteins of deciduous teeth.
