Clinical and radiological course in apicoectomies with the Erbium : YAG LASER
A study is made of the efficacy of the Erbium: YAG laser in granulomatous periapical lesions, based on clinical and radiographic controls. The study comprised a series of 45 patients amenable to periapical surgical treatment of incisors, canines and premolars. A conventional surgical technique was used, with silver amalgam retrograde filling and irradiation of the bone defect and remnant root cement with the Erbium: YAG laser. Clinical and radiographic controls were made during 24 months, assessing the absence of symptoms and the presence of pain, swelling or fistula and ossification of the lesions, respectively. The clinical course proved asymptomatic in 95.5% of the cases. As regards remo…
An observational study of the frequency of supernumerary teeth in a population of 2000 patients
An evaluation is made of the epidemiological characteristics of supernumerary teeth, with an analysis of the associated clinical-eruptive complications. A longitudinal observational study was made of 2000 patients, with the documentation of demographic data, the presence of supernumerary teeth, their location, mechanical accidents and the presence of associated pathology. The presence of supernumerary teeth was recorded in 1.05% of the study subjects (mean age 20.2 years), with a greater frequency in males. The most frequent location was in the upper maxilla (79.2%), fundamentally in the retromolar zone and at premaxillary level. The presence of mechanical accidents was the most frequent co…
Metaanalysis of the epidemiology and clinical manifestations of odontomas
Our objective was to evaluate the epidemiological and clinical aspects of the different types of odontomas. A metaanalysis was made of 3065 odontomas obtained from a literature review of 30 articles published in recent years. Odontomas show no gender predilection, and are most often diagnosed in the second decade of life. They are preferentially located in the upper maxilla, particularly in the anterior sector. Compound odontomas are more prevalent than complex odontoma, and show no predilection in terms of patient gender, age or location. Most such lesions are asymptomatic and constitute casual findings in X-ray studies indicated for other reasons. The most common clinical manifestations a…
Immediate post-extraction implants subject to immediate
Since Brånemark first started developing its implant system, there has been a continuous and significant evolution in oral implantology through experimental and clinical research, and many of the concepts that were once considered valid have now become the subject of debate. The insertion of the implant immediately after extraction of the tooth to be substituted has now become the implant treatment of choice and is associated with preserving the bone structure and the gingival architecture, as well as with reducing the treatment time, which ultimately benefits the patient. Objective: To evaluate the success rate of the immediate post-extraction implants (IPI) subject to immediate loading. S…
Metaanalysis of filler materials in periapical surgery
Our purpose was to evaluate the success and failure, apical sealing and biocompatibility of silver amalgam, IRM®, SuperEBA® and MTA as retrograde filler materials. A metaanalysis was made of filler materials in periapical surgery, evaluating a total of 30 articles published in recent years. Percentage success with silver amalgam was 76.5% and slightly inferior to that afforded by IRM®. Performance in turn increased considerably when the materials used were SuperEBA® or MTA. As regards marginal leakage, MTA with a mean leakage time of 65.5 days afforded the best results, followed by SuperEBA®, IRM® and silver amalgam. MTA was the most biocompatible of the materials studied, with practically …
Transmigrated canines: review and update
Transmigrated canines are impacted canines that have crossed the midline. Our objective was to evaluate the epidemiological and clinical aspects that have to do with transmigrated canines. We did a bibliographic review of 209 transmigrated canines obtained from a review of articles from 1971 to the present. The results of the study were that transmigrated canines are most frequent among females and are usually diagnosed within the first two decades of life. They are usually located in the mandible, with transmigration being most frequent in the left mandibular canine. In a large number of cases, the deciduous canine remains in the arcade. Transmigrated canines are most often found impacted,…
Social demand in ambulatory oral surgery. Experience in the Master of Oral Surgery of Madrid Complutense University (Spain)
Objectives. An evaluation is made of the surgical activity in the context of the Master of Oral Surgery (Madrid Complutense University, Madrid, Spain), together with an analysis of social demand in ambulatory oral surgery. Study design. A descriptive statistical analysis (frequency and contingency tables) is made of the different parameters relating to the activity carried out in this postgraduate master during two academic years. Results. A total of 6750 interventions were carried out in 5877 patients. Females predominated over males (62% versus 38%), and 59.2% of the subjects were in the 21-40 years age range. The most common procedure was tooth extraction (91%); of these, 83.5% correspon…
Efectos esterilizantes del láser Erbium:Yag sobre las estructuras dentarias: estudio in vitro
Objetivo: Comprobar el efecto esterilizante del láser de Erbium:YAG, a diferentes potencias, en dientes in vitro Diseño del estudio: Estudio in vitro sobre 47 dientes unirradiculares extraídos por motivos periodontales en la Unidad Docente de Cirugía Bucal y Maxilofacial (Departamento de Medicina y Cirugía Bucofacial) de la Facultad de Odontología de la Universidad Complutense de Madrid. Las muestras fueron divididas en tres grupos de irradiación con láser (250mJ, 350mJ y 450mJ) y un grupo control -no irradiados-. A continuación se introdujeron en un medio de enriquecimiento durante 72 horas en anaerobiosis, realizando controles visuales a las 24, 48 y 72 horas. Y posteriormente se realizar…
Sterilizing effects of the Erbium : Yag laser upon dental structures: An in vitro study
An evaluation was made of the sterilizing effects of the Erbium: YAG laser at different power ratings upon dental structures in vitro. An in vitro study was made of 47 single-root teeth removed for periodontal reasons in the Oral and Maxillofacial Surgery Teaching Unit (Department of Medicine and Orofacial Surgery, Madrid Complutense University Dental School, Spain). The teeth were divided into three laser irradiation groups (250, 350 and 450 mJ) and a non-irradiated control group. The teeth were then immersed in an enrichment medium for 72 hours under conditions of anaerobiosis, with visual controls after 24, 48 and 72 hours. Posteriorly, microbiological cultures were made in blood agar to…
