Radiotherapy
Radiotherapy is one of 3 treatment options that can be used to treat tumours, the other 2 being surgical removal and chemotherapy. Sometimes these therapies are used in combination with each other. There are many structures in the head and neck, therefore radiation to the head and neck area (could be due to oral, nose, skin etc cancers) can cause a multitude of complications as listed below: Continue reading
It is thought that as a result of inflammation of the facial nerve, pressure is produced on the nerve where it exits the skull within its bony canal, blocking the transmission of neural signals or damaging the nerve. Patients with facial palsy for which an underlying cause can be found are not considered to have Bell’s palsy per se. Possible causes include tumor, meningitis, stroke, diabetes mellitus, head trauma and inflammatory diseases of the cranial nerves (sarcoidosis, brucellosis, etc.). In these conditions, the neurologic findings are rarely restricted to the facial nerve. Babies can be born with facial palsy. In a few cases, bilateral facial palsy has been associated with acute HIV infection. Continue reading

A tooth is made up of enamel, dentine, and the pulp. Enamel is the hardest part of the body, even harder than any bone in your body. This is because enamel is made up of 90% inorganic matter, consisting mainly of hydroxyapatite crystals, which are essentially made up of calcium and phosphate.
After meals, the bacteria in the mouth will break down sugar or carbohydrate left on teeth surface, producing acids which will then cause demineralization of the teeth surface, depleting it of calcium and phosphate. This process starts in enamel, and can progress to the dentine and eventually pulp, causing pulpitis. Continue reading
Bell’s palsy is a form of facial paralysis resulting from a dysfunction of the cranial nerve VII (the facial nerve) that results in the inability to control facial muscles on the affected side. Several conditions can cause facial paralysis, e.g., brain tumor, stroke, and Lyme disease. However, if no specific cause can be identified, the condition is known as Bell’s palsy. Named after Scottish anatomist Charles Bell, who first described it, Bell’s palsy is the most common acute mononeuropathy (disease involving only one nerve) and is the most common cause of acute facial nerve paralysis.

The base of the flap should be wider than incisal margins for adequate blood flow to the reflected flap.
The flap should be designed with continuous curvatures between horizontal and vertical incision to avoid sharp angles

Fluoride rinsesare one of the many ways fluoride can be delivered to our teeth to prevent cavities. Studies on fluoride rinses have been made and in general, fluoride rinses resulted in significant cavities reduction of about 30 to 35%. On the basis of these findings, the simplicity of administration, and the lack of need for professional dental supervision, weekly fluoride-rinse programs in schools are becoming increasingly popular and are being aggressively promoted by dental public-health agencies. Fluoride rinses were approved as safe and effective by the FDA in 1974 and by the Council of Dental Therapeutics of the ADA in 1975. Continue reading
INTRODUCTION
Preservation of the dentition and maintenance of function are dental professions ultimate goal.
The advances in non surgical endodontic therapy has been explosive, but it has also been a mixed blessing.
It has led to procedural errors such as, broken instrument ,ledges etc
It is indicated in fewer than 5% of endodontically treated teeth. The success rate of endodontic surgery is high, ranging from 73-99%.
The neck dissection is a surgical procedure for control of neck lymph node metastasis from Squamous cell carcinoma (SCC) and Merkel cell carcinoma (MCC) of the head and neck. The aim of the procedure is to remove lymph nodes from one side of the neck into which cancer cells may have migrated. Metastasis of squamous cell carcinoma into the lymph nodes of the neck reduce survival and is the most important factor in the spread of the disease. The metastases may originate from SCC of the upper aerodigestive tract, including the oral cavity, tongue, nasopharynx, oropharynx, hypopharynx, and larynx, as well as the thyroid, parotid and posterior scalp.

Composite – in material science, a solid formed from two or more distinct phases (e.g. particles in a metal phase) that have been combined to produce properties superior to or intermediate to those of the individual constituents
Dental composite is defined as a highly cross-linked polymeric material reinforced by a dispersion of amorphous silica, glass, crystalline, or organic resin filler particles and/or short fibers bonded to the matrix by a coupling agent
