Systemic review of dry socket: aetiology, treatment, and prevention.

Our systemic review is to make a comprehensive review about the aetiology, treatment and the prevention of dry socket, the inclusion criteria were all the studies that discuss the dry socket and its etiology, treatment and prevention and exclusion criteria were all the studies that discuss the other complications of tooth extraction, the materials and methods used for this systemic review was to search in the Pub Medline database between 2008 to 2013, using specific words "dry socket, aetiology, treatment and prevention" and published in the English language, the articles were screened by abstract for relevance to aetiology, treatment and prevention of dry socket, 82 papers were identified in pub med but a total of 36 out of Publications were included in the final systemic review according to the specific keywords and materials mentioned above. The occurrence of dry socket in an everyday oral surgery or dental practice is unavoidable. The risk factors are smoking, surgical trauma, single extractions, age, sex, medical history, systemic disorder, extraction site, amount of anaesthesia, operator experience, antibiotics use prior to surgery, difficulty of the surgery and the previous surgical site infection in addition to oral Contraceptives, menstrual cycle and immediate postextraction socket irrigation with normal saline.

Oral manifestations of Parry-Romberg syndrome: A review of literature.

Parry-Romberg syndrome (PRS) or progressive facial hemiatrophy is a developmental craniofacial disorder of unknown etiology characterized by a slowly progressive unilateral facial atrophy. It is associated with different systemic manifestations particularly, maxillofacial, neurologic and ophthalmologic abnormalities. Dentists must be aware of PRS to identify this invalidating disorder.

Immunohistochemical comparison of p53, Ki-67, CD68, vimentin, α-smooth muscle actin and alpha-1-antichymotry-psin in oral peripheral and central giant cell granuloma.

Introduction: Giant cell lesions are characterised histologically by multinucleated giant cells in a background of ovoid to spindle-shaped mesenchymal cells. There is a major debate whether these lesions are separate entities or variants of the same disease. Our aim was to study the nature of multinucleated and mononuclear cells from peripheral giant cell granuloma (PGCG), and central giant cell granuloma (CGCG) and giant cell tumor (GCT) of long bones using immunohistochemistry evaluation and to determine whether there is a correlation between recurrence and the markers used.

Maspin as a tumour suppressor in salivary gland tumour.

Maspin is a protein that belongs to serin protease inhibitor (serpin) superfamily. The purpose of this study was to review the literature concerning the expression of maspin in salivary gland tumours. A literature search was done using MEDLINE, accessed via the National Library of Medicine PubMed interface.

An unusual side effect of Ibuprofen post dental therapy: increased erectile and libido activity.

Nonsteroidal anti-inflammatory drugs are the most commonly used medications for pain control in dentistry. The reported adverse effects include gastrointestinal and cardiovascular events, alterations in renal function, and effects on blood pressure, hepatic injury, and platelet inhibition which can lead to increased bleeding. This case report describes an unusual rare adverse event of the use of ibuprofen for pain control post restorative treatment.

Vitamin D and its relationship with breast cancer: an evidence based practice paper.

Background: In oncology research fields, vitamin D has emerged as the most fruitful issue. The previous decade witnessed intensive efforts in connecting vitamin D with risk reduction and progression of various epithelial cancers, especially, breast cancer.

Purpose: To evaluate the relationship between vitamin D levels and breast cancer.

Prevalence and severity of plaque-induced gingivitis in a Saudi adult population.

Objectives: To evaluate the prevalence and severity of plaque-induced gingivitis among a Saudi adult population in Riyadh region.

Methods: Three hundred and eighty-five eligible participants in this cross-sectional study were recruited from routine dental patients attending the oral diagnosis clinic at Al-Farabi College in Riyadh, Saudi Arabia from June 2013 to December 2013. A clinical examination was performed by 2 dentists to measure the gingival and plaque indices of Löe and Silness for each participant.

Using an existing crown to repair a damaged cast post and core restoration.

A fractured coronal tooth structure beneath an intact crown is a common clinical occurrence. If the underlying root is healthy, the tooth is restored with a post and core followed by refabrication of the crown. This paper describes a technique of using the existing intact crown for the above-mentioned situation.

Oral cancer awareness among future dental practitioners may have an impact on the early detection and prevention of oral cancer. A cross-sectional survey was undertaken to assess the current knowledge of future Saudi dentists on oral cancer and their opinions on oral cancer prevention. A pretested questionnaire was sent to 550 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia.

Expression of p21 is dependent on or independent of p53 in carcinoma ex pleomorphic adenoma (undifferentiated and adenocarcinoma types).

Our study is aimed to characterize alteration in the immunohistochemical expression of p21 and p53 in normal tissue of the salivary gland surrounding carcinoma arising in pleomorphic adenoma, and the tumor cells of carcinoma arising in pleomorphic adenoma as well as to identify whether the induction of expression p21 is dependent on or independent of p53 in carcinoma arising in pleomorphic adenoma. A selected series of 27 cases of carcinoma ex pleomorphic adenoma (undifferentiated and adenocarcinoma types) was examined. The results showed that p21 and p53 expression was negative in the most components of normal tissue of the salivary gland surrounding carcinoma arising in pleomorphic adenoma.

Cryosurgery of the oral and peri-oral region: a literature review of the mechanism, tissue response, and clinical applications.

Cryosurgery is a method of achieving lesion destruction by rapid freezing in situ. Application of cryosurgery in medicine widespread and its use within dentistry is also well documented, using both open and closed liquid nitrogen and carbon dioxide. The major advantages of oral cryosurgery include bloodless treatment, very low incidence of secondary infection, and a relative lack of scarring and pain.
