The Effect of Thermocycling and Mechanical Loading on the Fracture Resistance of Graphene and All-Ceramic Anterior Crowns.

Introduction Fixed prosthodontic treatment involves the replacement of missing tooth structures with a variety of materials. Several newer metal-free ceramics have been developed in recent years to meet patients' aesthetic needs. The long-term performance of all ceramics, however, is unknown, necessitating a continuous evaluation of the materials' strength.

A Clinical Study on Comparative Evaluation of the Effectiveness of Carbamazepine and Combination of Carbamazepine with Baclofen or Capsaicin in the Management of Trigeminal Neuralgia.

Background: Trigeminal neuralgia (TN) is characterized by recurrent attacks of lancinating pain in the trigeminal nerve distribution. Various medicinal and surgical procedures have been utilized for the treatment of TN. Over the time, several drugs other than carbamazepine have been used but none of them have shown satisfying results.

Tumor Infiltration Depth as a Prognostic Parameter for Nodal Metastasis in Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma (OSCC) has locoregional evolution, with frequent neck involvement. Significant number of studies have been undertaken to assess the parameters for treatment of N0 neck patients with a high likelihood of harboring occult node metastases. Many studies have indicated tumor infiltration depth (or tumor thickness) as one of the most important criteria in determining the further management.

Serum levels of antioxidants and superoxide dismutase in periodontitis patients with diabetes type 2.

Aims And Objectives: The present study was designed to estimate and compare the superoxide dismutase and total antioxidant capacity levels in the serum of diabetes mellitus - Type 2 patients and healthy individuals with and without periodontal disease.

Materials And Methods: The study was designed as a case-control study comprising of 150 subjects, inclusive of both genders in the age group of 35-65 years. They were divided into three groups of 50 patients each.

Comparative evaluation of serum antioxidant levels in periodontally diseased patients: An interventional study.

Background: Periodontal disease is an immune-inflammatory disease characterized by connective tissue breakdown, loss of attachment and alveolar bone resorption. In normal physiology, there is a dynamic equilibrium between reactive oxygen species activity and antioxidant defense capacity and when that equilibrium shifts in favor of reactive oxygen species, oxidative stress results. Oxidative stress is thought to play a causative role in the pathogenesis of periodontal diseases.

New mathematical derivations for calculation of ATP yield due to the complete oxidation of different types of fatty acids.

During the complete oxidation of fatty acids, the electrons removed from fatty acids in different forms (FADH2 and NADH2) pass through the respiratory chain, driving the ATP synthesis. Generally, the ATP yield due to the complete oxidation of fatty acids is calculated by sum total the ATPs obtained due to the oxidation of FADH2 and NADH2 due to lack of any particular method. This calculation is simple for saturated even numbered fatty acids, but in the case of saturated and unsaturated odd numbered fatty acids the calculation of ATP yield is difficult and needs mathematical calculations due to some changes in their beta-oxidation pathway when compared to the pathway of saturated even numbered fatty acids.

Remote endarterectomy: an alternative to surgical bypass.

We present our preliminary results of remote endarterectomy performed during June 2003 to June 2010. 8 cases of unilateral ileofemoral disease, 3 cases of bilateral ileofemoral disease and 4 cases of femoro-popliteal disease constituting 18 limbs were successfully operated. All patients had comorbid conditions like Diabetes mellitus, hypertension, cardiac disease and smoking.

Evaluation of micronutrient (zinc, copper and iron) levels in periodontitis patients with and without diabetes mellitus type 2: a biochemical study.

Context: Periodontal tissue destruction is caused by an inappropriate host response to microorganisms. Diabetes is a metabolic disease and most of its complications are due to hyperglycemia. Periodontitis is considered as its sixth complication.

A comparative evaluation of antioxidant enzymes and selenium in the serum of periodontitis patients with diabetes mellitus type 2.

Context: Chronic periodontitis is an inflammatory disease with an aberrant response characterized by exaggerated inflammation, involving the release of excess proteolytic enzymes and reactive oxygen species (ROS). Diabetes mellitus is a group of complex multisystem metabolic disorders characterized by a relative or absolute insufficiency of insulin secretion and or concomitant resistance to the metabolic action of insulin on target tissues. Increased production of ROS necessitates elevated requirements for the nutrients involved in antioxidant defenses: Selenium, zinc, and copper.

Characteristics of associated craniofacial trauma in patients with head injuries: An experience with 100 cases.

Background: Facial fractures and concomitant cranial injuries carry the significant potential for mortality and neurological morbidity mainly in young adults.

Aims And Objectives: To analyze the characteristics of head injuries and associated facial injuries, the management options and outcome following cranio-facial trauma.

Methods: This retrospective review was performed at Justice K.
