Oral manifestations of HIV/AIDS in Asia: Systematic review and future research guidelines
2015
Objectives: The authors have conducted a systematic review of oral manifestations of HIV from studies conducted in Asia to establish the characteristics and prevalence of individual oral manifestations in Asia, and to assess the direction of future research studies on oral manifestations of HIV in Asia. Material and Methods: The electronic retrieval systems and databases searched for relevant articles were PubMed [MEDLINE], EBSCO, and EMBASE. The search was for limited articles published in English or with an English abstract and articles published during the period January 1995 to August 2014. The authors reached a final overall sample of 39 studies that were conducted in Asia. Results: Th…
Alendronate-associated osteonecrosis of the jaws: a review of the main topics
2013
Bisphosphonates is a group of inorganic pyrophosphates analogues that suppress bone resorption by inducing osteoclast inactivation, being frequently used for management of diseases affecting bone metabolism, bone metastases and bone tumors. However, since 2003 many cases describing the presence of necrotic bone exposures in the jaws have been described in patients receiving these drugs, what represent a significant complication of bisphosphonates treatment. The overall incidence of bisphosphonate-related osteonecrosis of the jaws is low, ranging from 0.7% to 12%, mainly observed in those patients receiving intravenously treatment. Osteonecrosis of the jaws associated to oral bisphosphonate,…
A critical assessment of oral care protocols for patients under radiation therapy in the regional University Hospital Network of Madrid (Spain)
2015
Background: This research was aimed to critically evaluate, under the light of the available scientific evidence, the oral care protocols recommended by different hospitals in head and neck cancer (HNC) patients under radiation therapy. Material and Methods: A questionnaire requesting all the relevant information for the oral care of these patients was sent to the 9 University Hospitals in Madrid. The answers were categorized and analyzed. In addition, an electronic search was conducted to identify the most relevant papers (systematic reviews [SR] and randomized clinical trials [RCTs]) assessing oral care protocols for patients treated for HNC with radiation therapy. Results: Eight out of n…
Traumatic neuroma of the mandible: a case report with spontaneous remission
2014
Traumatic neuroma is a well-known disorder involving peripheral nerves, which occurs following trauma or surgery. The lesion develops most commonly in the soft tissues of the mental foramen area, lower lip and tongue. Intra-osseous lesions arising in jawbones are very uncommon. In this paper, we report a new case of an intra-osseous traumatic neuroma, discovered incidentally on a panoramic radiograph obtained for orthodontic documentation. In addition, the case herein described developed spontaneous remission, a situation not previously reported in the literature. Finally, we discuss relevant demographic, clinical, microscopic, immunohistochemical and treatment aspects of traumatic neuromas…
Gossypiboma in the oral region: case report and literature review
2014
Gossypiboma is an inflammatory reaction to a foreign body, specifically composed of a cotton matrix left behind after surgery. The present study aims to present a case report of gossypiboma 23 years after a dental surgery and to make a literature review of the English language cases published on the issue. A 42-year-old woman was attended to evaluate complaints of pain on the right side of the maxilla. The patient reported that dental extractions in this region had been performed over a period of nearly 23 years. The panoramic radiograph demonstrated an opacity in the right maxillary sinus, which presented a spongiform aspect, irregularly shaped radiopaque image, as well as a rupture of the…
Cavernous hemangioma of the parotid gland in adults
2014
Hemangiomas account for 0.4-0.6% of all tumors of the parotid gland and most of them occur in children, nevertheless in adults hemangiomas are very rare. We report the case of a 62 year old woman with a mass in the parotid right tail associated with fluctuating swelling episodes unrelated to meals and with a slowly progressive growth. The provisional diagnosis was a pleomorphic adenoma, so a right superficial parotidectomy was performed. During surgery, the macroscopic appearance makes suspect a vascular lesion. The histopathological result was a cavernous hemangioma. The classic clinical presentation of a parotid hemangioma is an intraglandular mass associated or not with skin lesions char…
Orthopantomography contribution to prevent isquemic stroke.
2014
Objectives: The ortopantomography (OPG) can be a valuable way for an early detection of calcified atheroma plaques, thus contributing for a preliminary stroke risk evaluation. The study looks for the existence of calcified atheroma plates through the use of OPG, comparing the results with the stenosis percentage found through eco-doppler. It has been analyzed the correlation of the number of years as a smoker, arterial hypertension and body mass index, against the risk of having calcified atheroma plaques. Study Design: Observational, transversal and prospective study with 84 patients from the Dental Center of Hospital Particular de Lisboa. First the patients answered to an inquiry and them…
Dental management in transplant patients
2011
Introduction: Transplant is the replacement with therapeutic purposes, of organs, tissues or cellular material for others, from a donor who is usually a human, alive or dead. In recent years, transplant organs have been developed by the advances that have occurred with immunosuppressive drugs and medical-surgical technology. Due to the frequency of transplants that are performed today, it is common to find these patients in dental clinics. Objectives: To review the literature on oral manifestations in transplant patients and general dental management and according to transplant organs (heart, lung, liver, kidney, pancreas and bone marrow). Material and Methods: For the literature review, we…
Oral pigmented lesions: clinicopathologic features and review of the literature
2012
Diagnosis of pigmented lesions of the oral cavity and perioral tissues is challenging. Even though epidemiology may be of some help in orientating the clinician and even though some lesions may confidently be diagnosed on clinical grounds alone, the definitive diagnosis usually requires histopathologic evaluation. Oral pigmentation can be physiological or pathological, and exogenous or endogenous. Color, location, distribution, and duration as well as drugs use, family history, and change in pattern are important for the differential diagnosis. Dark or black pigmented lesions can be focal, multifocal or diffuse macules, including entities such as racial pigmentation, melanotic macule, melan…
Reactive hyperplastic lesions of the oral cavity: A ten year observational study on North Indian Population.
2011
Back ground: The aim of this study was to determine the frequency of focal reactive hyperplastic lesions of the oral cavity as reported in the Department of Oral Pathology and Microbiology, Subharti Dental College, Meerut and to compare these data with those of previously reported studies from other regions and countries. Material and Method: Patient records of the Department of Oral Pathology were retrieved during a 10 year period from 2001 to 2010. Data of all reactive hyperplasias namely focal fibrous hyperplasia (FFH), pyogenic granuloma (PG), peripheral ossifying fibroma (POF) and peripheral giant cell granuloma (PGCG) were reviewed and analyzed for age, gender, and site of location.
