Capillary Haemangioma of Gingiva - A Rare Lesion.

Capillary Haemangioma is a benign vascular tumour characterized by proliferation of blood vessels with a very striking similarity to pyogenic granuloma with a predilection to occur on the gingiva. Though the head and neck are the most common region of occurrence, but is considered to be rare occurring on the gingiva, intra-orally. The lesion clinically mimicked pyogenic granuloma but was histopathologically diagnosed as capillary haemangioma.

Orthokeratinised odontogenic cyst: A case series.

Orthokeratinised odontogenic cyst (OOC) is a distinct and an uncommon odontogenic cyst of jaw. It was previously considered as orthokeratinized variant of Odontogenic Keratocyst, owing to its same site, age and occurrence and origin. In 2017 WHO classified OOC under odontogenic cysts as a distinct entity, clearly separating it from Odontogenic Keratocyst (OKC).

Oxidative stress marker in oral cancer: A review.

Oxygen derived species such as hydrogen peroxide, superoxide anion radical, hydroxyl radical (OH-), and singlet oxygen are well known to be cytotoxic and have been implicated in the etiology of a wide array of human diseases, including cancer. Various carcinogens may also partly exert their effect by generating reactive oxygen species (ROS) during their metabolism. Oxidative damage to cellular DNA can lead to mutations and may, therefore, play an important role in the initiation and progression of multistage carcinogenesis.

Influence of application of chlorhexidine gel and curcumin gel as an adjunct to scaling and root planing: A interventional study.

Background: Currently, the most common therapy for periodontal diseases consists of professional scaling and root planing (SRP). However, it was found to be of limited efficacy especially in areas which are inaccessible to periodontal instrumentation. Therefore, treatment strategies using antimicrobials in conjunction with conventional therapy have evolved.

Immunohistochemical expression of vascular endothelial growth factor in keratocystic odontogenic tumor, dentigerous cyst, and radicular cyst: A comparative study.

Background: Cyst and tumors arise from tissue remains of odontogenesis, these interactions have been considered to play an important role in the tumorigenesis of odontogenic lesions. The connective tissue stroma has an essential role in the preservation of epithelial tissues and minor alterations in the epithelium are followed by corresponding changes in the stroma, such as angiogenesis. Vascular endothelial growth factor (VEGF) is considered the first factor which maintains its position as the most critical driver of vascular formation and is required to initiate the formation of immature vessels, with this aim, present study was executed to evaluate VEGF expression in kertocystic odontogenic tumor, dentigerous cyst and radicular cyst (RC).

Evaluation of the Secretor Status of ABO Blood Group Antigens in Saliva among Southern Rajasthan Population Using Absorption Inhibition Method.

Introduction: The ABO blood group system was the significant element for forensic serological examination of blood and body fluids in the past before the wide adaptation of DNA typing. A significant proportion of individuals (80%) are secretors, meaning that antigens present in the blood are also found in other body fluids such as saliva. Absorption inhibition is one such method that works by reducing strength of an antiserum based on type and amount of antigen present in the stains.

Evaluation of stromal myofibroblasts in oral leukoplakia, oral submucous fibrosis, and oral squamous cell carcinoma--an immunohistochemical study.

Background: Oral leukoplakia (OL) and oral submucous fibrosis (OSMF) are the main potentially malignant disorders and oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral mucosa. Myofibroblasts (MFs) secrete numerous growth factors and inflammatory mediators that stimulate epithelial cell proliferation and play an important role in tumoral invasion and use a combination of different factors in the course of neoplastic growth and development. Hence the present study was undertaken to evaluate and compare the distribution of MFs using alpha smooth muscle actin (α-SMA) in OL, OSMF, and various histopathological grades OSCC.

A study of C-reactive protein, lipid metabolism and peripheral blood to identify a link between periodontitis and cardiovascular disease.

Periodontitis is characterized by systemic inflammatory host responses that may contribute to a higher risk for cardiovascular disease. We hypothesized that periodontitis may be associated with altered C-reactive protein levels, serum levels of lipids and peripheral blood counts, and that these characteristics may serve as markers for a link between periodontitis and cardiovascular disease. Sixty subjects, 25-60 years old, were divided into three groups of 20 subjects each.

Evaluation of salivary and serum lipid peroxidation, and glutathione in oral leukoplakia and oral squamous cell carcinoma.

Lipid peroxidation induced by reactive oxygen species (ROS) is involved in the pathogenesis of malignancy. Overall, lipid peroxidation levels are indicated by malondialdehyde (MDA), which is the most frequently used biomarker to detect oxidative changes. Antioxidant defense systems such as glutathione (GSH) limit cell injury induced by ROS.
