Coronectomy of lower third molars in intimate relation to the inferior alveolar nerve: A report of two cases.

Damage to the inferior alveolar nerve (IAN) secondary to the extraction of the lower third molar (LTM) is a relatively frequent complication (0.35-8.40%) that can cause temporary or permanent nerve damage. Coronectomy has been proposed as an alternative, which consists of sectioning the coronary portion of the LTM, and deliberately leaving the radicular portion with the pulp intact. Two clinical cases are presented in this article, in which root migration (0-0.3 mm) and a change of angulation (+2º to +9°) occurred. None of the cases developed complications during the follow-up period (12 months). Therefore, coronectomy is a procedure to be considered in selected cases as an alternative to conventional exodontia of the LTM to avoid possible damage to the IAN. Key words:Case report, third molar, mandibular third molar, coronectomy, mandibular nerve, mandibular nerve injuries, root migration.

Enfermedad ampollosa autoimnume de cavidad oral: pénfigo vulgar. A propósito de un caso clínico / Blistering autoimmune disease of the oral cavity: pemphigus vulgaris. Case report

Las enfermedades ampollosas de cavidad oral son un grupo de enfermedades poco frecuente y de carácter autoinmune. Se conocen seis formas de pénfigo: vulgar, vegetante, inmunoglobulina A, foliáceo, eritematoso y paraneoplásico. Este tipo de lesiones pueden presentarse de los 50 a los 65 años de edad, existiendo una predilección por el sexo femenino. La manifestación inicial se produce en la cavidad oral como ulceraciones múltiples precedidas por ampollas que se rompen y luego se extienden a otras membranas mucosas y la piel, y en ciertas ocasiones a nivel esofágico, cursando este con odinofagia y disfagia. Es fundamental el diagnóstico, así como un tratamiento precoz de estos pacientes. Actualmente se obtiene un mejor pronóstico y evolución en aquellos pacientes que presentan una respuesta rápida al tratamiento con corticoides

Blistering diseases of the oral cavity are rare and autoimmune disease. Six types of penis are characterized: vulgar, vegetative, immunoglobulin A, foliaceous, erythematous and paraneoplastic. This type of injury can occur at 50 years of age, with a predilection for females. The initial manifestation occurs in the oral cavity as multiple ulcerations preceded by blisters that rupture and then spread to other mucous membranes and skin, and sometimes at the esophageal level, with odynophagia and dysphagia. It is fundamental the diagnosis as well as an early treatment of these patients, currently there is a better prognosis and a better evolution in those patients who present a rapid response to treatment with corticosteroids
