Cannabis can be related to respiratory diseases, but the relationship between smoking marijuana and development of a pneumothorax has scarcely been investigated. We aimed analyze, in patients with history cannabis abuse submitted lung apicectomy for primary spontaneous (PSP), correlation presence cannabinoids resected detection bullous emphysema within same tissue. Patients undergoing PSP were ...
Abstract Background A radicular cyst is an inflammatory of odontogenic nature, formed by cells Malassez in the periodontal ligament, which are stimulated and proliferate, following insults such as dental trauma. First stage treatment commonly orthograde root canal (RCT), followed apicectomy or extraction enucleation lesion +/- bone grafting replacement tooth. Presenting problem This case illust...
OBJECTIVES To investigate apicectomies performed using burs, a CO2 laser or an Er:YAG laser and to evaluate the following aspects: morphology of apicectomized surfaces, presence of failures at the dentin/obturation material interface (marginal fit) of the apical portions of the root canals, and the proportions of chemical elements in the apicectomized surfaces. STUDY DESIGN Twenty-four teeth ...
With our study we wanted to compare the diagnostic accuracy of conventional radiography (orthopanoramic and intraoral radiography) and Cone Beam CT (CBCT) for the diagnosis of periapical lesions on the posterior elements of the upper maxilla endodontically treated.The images were analyzed by a radiologist and an endodontist whose interpretation of radiological examinations is unique. Were exami...
OBJECTIVES Recent studies have investigated the occurrence of human cytomegalovirus and Epstein-Barr Virus in samples from apical periodontitis lesions and a role in the pathogenesis of this disease has been suggested. Because genotype distribution and seroprevalence of EBV and HCMV differ among populations, it is important to determine the presence of these viruses in endodontic periapical les...
Biomaterials such as membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. A combination of apical surgery and these biomaterials is one of the latest treatment options for avoiding tooth extraction. In case of periapical lesions, guided tissue regeneration (GTR) is attempted to improve the self-regenerative healing process by excluding undesired prolifer...
Background and Objectives: The most recent technological breakthroughs incorporated in the latest generation of Variable Square Pulse (VSP) Er:YAG dental lasers involve two additional features: SSP (Super Short Pulse) mode for extremely fine and minimally invasive laser ablation; and MAX mode for maximum optical drilling speeds. The objective of this study was to make a comparison between the t...
