Panoramic radiography (OPG) evaluates mandibular third molar impaction (MTMI). This systematic review aimed to investigate the diagnostic accuracy of OPG in detecting bone loss distal to the lower second molars. The associated bone loss with different impaction positions and the most prevalent positions of MTMI were investigated as secondary outcomes.

Several nerves, muscles, and ligaments are related closely to the (SP). It is considered elongated when the measurement exceeds 30 mm.

Materials And Methods: A literature search in MEDLINE with the keywords "dental implant connections, external internal implant connection, bone loss implant designs, internal and external connection implant studies in humans" was conducted. Clinical trials on human beings, comparing both connections and published in English, from 2010 to 2016 were selected.
The aim of this study was to compare the immediate postoperative period of participants rehabilitated with dental implants placed with a conventional technique or with a minimally invasive technique, without a mucoperiosteal flap elevation (flapless). Participants who needed implant placement were divided into two groups: one group was operated using a mucoperiosteal flap elevation (G_A), and the other with a flapless surgical technique (G_B). Objective clinical parameters including oral hygiene, mouth opening, inflammation (facial perimeter), surgical time and analgesic consumption, as well as subjective parameters of pain and degree of satisfaction with the procedure, were evaluated.

However, the number of studies that would allow a better understanding of etiological factors and clinical features, particularly in the Portuguese population, is very limited. This study was based on patients with squamous cell carcinoma of the anterior two thirds of the tongue that were treated at the Department of Head and Neck Surgery of the "Instituto Portugues de Oncologia de Lisboa - Francisco Gentil" (IPOLFG) in Lisbon, Portugal, between January 1, 2001 and December 31, 2009.

Chronic inflammation is a risk factor for developing oral squamous cell carcinoma (OSCC).
Objectives: To review the literature of cases that associate implant placement with the development of oral cancer.
Bifid mandibular condyle is a rare anomaly; there are several theories about its etiology, and it has been studied in both prehistoric and historic skulls, as well as in living human beings. It is a frequent, although unexpected, finding in asymptomatic individuals during radiological treatment. Presented here is a review of the literature over the past 10 years and two new cases of unilateral bifid condyle.

It has various forms of clinical expression. It is classified as one of what are known as Phacomatoses (phakos stain and oma tumour), which are development anomalies that can originate tumours and/or hamartomas in the nervous system.

Unfortunately, due to delays in diagnosis the 5-year survival rate is only 25%. For this reason, any measures to restrict the consumption of tobacco and alcohol and that will help preserve oral health and maintain a balanced diet will lead to benefits in terms of a reduction in the occurrence of this pathology.
View Article and Find Full Text PDFHumans are characterized by a compulsive tendency to distinguish themselves from the rest: differences in clothes, hairstyle or "decorative" details are used to this effect, based on highly diverse criteria. Such differentiating practices may be aimed at identification with a certain ideological group, for example, or with a concrete "fashion", and involve the use of jewelry, clothes, unusual attire, hairstyles, mutilations, etc. In this context, the present review addresses certain aspects of mutilation practices from both the general and specifically dental perspectives.
