Comparative evaluation of bond strength of self-adhering flowable composites to the dentin prepared with different burs: An study.

Aim: The aim of this study was to evaluate the shear bond strength (SBS) of self-adhering flowable composites on the dentinal surface prepared with carbide and diamond burs.

Materials And Methods: A total of 64 extracted mandibular molars were mounted on acrylic resin blocks, and the coronal part of the dentin was exposed and polished. Then, they were divided into Group 1 and Group 2 for carbide and diamond bur preparation, respectively.

Role of mast cells in inflammatory and reactive pathologies of pulp, periapical area and periodontium.

Mast cells (MCs) have been discovered over 130 years ago; their function was almost exclusively linked to allergic affections. At the time being, it is well known that MCs possess a great variety of roles, in both physiologic and pathologic conditions. In the oral tissues, MCs release different pro-inflammatory cytokines and tumor necrosis factor-alpha that promote leukocyte infiltration in various inflammatory states of the oral cavity.

Mucormycosis in immunocompetent patient resulting in extensive maxillary sequestration.

Mucormycosis or zygomycosis, also called phycomycosis, is an uncommon, invasive, potentially lethal and an aggressive fungal infection of the order that usually affects patients with alteration of their immunological system. From its initial description (Paltauf, 1885), this entity still has a high mortality. Imaging techniques are not usually diagnostic, and cultures are not totally reliable.

Prevalence of nasal carriers of methicillin-resistant among dental students: An study.

Aim: The aim of this study is to evaluate the prevalence of nasal carriage of coagulase positive methicillin-resistant (MRSA) among dental students.

Materials And Methods: Four hundred dental students, divided into two groups - undergraduates (200) and postgraduates (200), were screened using sterile cotton swabs for carriage of MRSA in anterior nares. The samples were inoculated on HiCrome MeReSa Agar Base-with cefoxitin supplement.

Perineural Invasion of Oral Squamous Cell Carcinoma: A New Hurdle for Surgeons.

The high rate of mortality associated with cancer is due to its inherent nature to metastasize. Perineural invasion (PNI) is a relatively rare mode of metastasis, and a distinct pathologic entity that can be observed in the absence of lymphatic or vascular invasion which is still shrouded by mystery. PNI is a marker of poor prognosis.

Epidermal growth factor receptor: Role in human cancer.

Cells are constantly exposed to various external stimuli which regulate the growth and survival of the cells. The signal transduction from the external environment to the interior of the cell is carried out by cell surface or transmembrane receptors. Epidermal growth factor receptor (EGFR) is a type I receptor tyrosine kinase and along with its ligands, EGFR is involved in the regulation of multiple cellular pathways.

Management of squamous cell carcinoma of the maxillary sinus.

Surgical management of malignant tumors disfigures and demoralizes individuals. Management of such patients requires concern humane approach, meticulous planning and judicious management of a case. It is the responsibility of a dentist to restore the lost function, speech and esthetics.

Epigenetics in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is the most common type of oral neoplasm, accounting for over 90% of all oral malignancies and 38% of head and neck tumors. Worldwide, OSCC is the eighth most common human cancer, with more than 500,000 new cases being diagnosed every year with a fairly onerous prognosis, encouraging further research on factors that might modify disease outcome. Genetic and/or environmental risk factors associated with the development of oral cancer have been sufficiently understood (smoking, alcohol, betel, diet, living habits, etc.

Mast cells and angiogenesis in malignant and premalignant oral lesions: An immunohistochemical study.

Introduction And Objectives: Angiogenesis is a complex event facilitated by angiogenic factors released from neoplastic and host immune cells. Among host immune cells, mast cells (MCs) may have greater significance in tumor progression through angiogenesis. The objectives of the study were to evaluate and correlate mast cell density (MCD) and microvessel density (MVD) in normal gingival tissue, leukoplakia with and without dysplasia and oral squamous cell carcinoma (OSCC) cases.

Juxtaoral organ of Chievitz: An innocuous organ to be known.

The Juxtaoral Organ of Chievitz is a normal anatomical structure located within the soft tissue in the buccotemporal fascia on the medial surface of the ascending ramus. This enigmatic vestigial structure is considered to be of neuroepithelial origin with no known function. As a matter of fact, JOOC is one of the most treacherous pitfalls in surgical pathology with respect to lesions in the head and neck area.

A Randomized Controlled Study Comparing Efficacy of Classical and Gow-Gates Technique for Providing Anesthesia During Surgical Removal of Impacted Mandibular Third Molar: A Split Mouth Design.

Introduction: Reliable profound mandibular block anesthesia is questionable when depositing the anesthetic solution at the lingula. The Gow-Gates technique is an useful alternative to the classical inferior alveolar nerve block and the incidence of unsuccessful anesthesia may be as high as classical technique. The aim of this study is to compare the clinical efficacy, degree of patient acceptability, advantages, disadvantages and limitations of the classical and Gow-Gates techniques for providing anesthesia in patients undergoing bilateral symmetrical surgical removal of impacted mandibular third molar under local anesthesia.

Efficacy of triphala extract and chlorhexidine mouth rinse against plaque accumulation and gingival inflammation among female undergraduates: A randomized controlled trial.

Aim: To know the efficacy of Triphala extract and Chlorhexidine mouth rinse against plaque and gingival inflammation.

Materials And Methods: A double blinded parallel arm randomised control trial was done among 60 participants aged 18-24 years. Participants were randomly allotted to three groups with 20 participants in each group of 0.

Single Miniplate Fixation for Mandibular Symphysis and Parasymphysis Fracture as a Viable Alternative to Conventional Plating Based on Champy's Principles: A Prospective Comparative Clinical Study.

Unlabelled: To compare long term and short term outcomes of fixing mandibular symphysis and parasymphysis fractures with single mini plate and conventional fixation using two mini plates.

Study Design: in this prospective clinical comparative study, 30 patients with fracture in study region were randomly divided into two groups. Group A patients received single 2.

Comparison of 'sutureless' Transconjunctival and Subciliary Approach for Treatment of Infraorbital Rim Fractures: a Clinical Study.

Purpose: The aim of the study is to compare subciliary incision and 'sutureless' transconjunctival incision in the treatment of infraorbital rim fractures.

Materials And Method: In this prospective study, 40 patients with fractures of the infraorbital rim were selected and divided into 2 groups using random sampling technique. Group A patients were treated using 'sutureless' transconjunctival technique and group B patients were treated using subciliary approach.

Comparative efficacy of aloe vera mouthwash and chlorhexidine on periodontal health: A randomized controlled trial.

Background: With introduction of many herbal medicines, dentistry has recently evidenced shift of approach for treating many inflammatory oral diseases by using such modalities. Aloe vera is one such product exhibiting multiple benefits and has gained considerable importance in clinical research recently.

Aim: To compare the efficacy of Aloevera and Chlorhexidine mouthwash on Periodontal Health.
