In a restaurant, a menu is a list of food and beverage offered to the customer. A menu may be Ã  la carte â which guests use to choose from a list of options â or table d'hÃ´te, in which case a pre-established sequence of courses is served.
A dental sinus is an abnormal channel that drains from a longstanding dental abscess associated with a necrotic or dead tooth. A dental sinus may drain to: 1  the inside of the mouth (an intraoral sinus), or,  the skin surface of the face or neck (an extraoral, orofacial sinus)
Presently, root canal cavities as well as other dental cavities are obturated by filling them with heated gutta-percha. Gutta-percha is a purified, coagulated, milkly exudate obtained from certain species of trees, and is defined as a trans isomer of rubber.
