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)
There are 3 types of dental abscess: 1  Gingival abscess-the abscess is only in the gum tissue and does not affect the tooth or the periodontal ligament. 2  Periodontal abscess-this abscess starts in the supporting bone tissue structures of the teeth.
