What are the surfaces of an anterior tooth?
Incisal – The biting edge of an anterior tooth. Lingual – The surface that faces the tongue. Mesial – The surface that is closest to the midline of the face. Occlusal – The chewing surface of posterior teeth.
What are the surfaces of anterior and posterior teeth?
As shown in Figure 5, the surfaces of anterior teeth facing the lips are referred to as labial surfaces, while the surfaces of posterior teeth facing the buccal mucosa are called buccal surfaces. Surfaces of posterior teeth which occlude opposing posterior surfaces are called occlusal surfaces.
What are the different surfaces of a tooth?
These surfaces are:Occlusal – The chewing surface of the tooth.Mesial – The forward side of the tooth. ... Distal – The back side of the tooth.Buccal – The cheek-side of the tooth. ... Lingual – The part of the tooth that is closest to the tongue.May 12, 2018
What is the surface of top of the tooth?
Palatal – Just like Lingual, this is the surface of a tooth that is closest or next to your tongue., but on your upper teeth this is called the palatal surface. Mesial and distal — These are the sides that come into contact with adjacent teeth.Mar 1, 2016
What is the interproximal surface of a tooth?
Description. The interproximal surface concerns the surfaces between each teeth. For example, interproximal teeth refers to the space between adjacent teeth. is the direction towards the last tooth in each quadrant of a dental arch, as opposed to mesial, which refers to the direction towards the anterior midline.
Which tooth surface of the anterior teeth is nearest the lips?
Labial: The tooth surface that lies towards the lips. Buccal: The tooth surfaces that lie towards the cheeks.
What is the proximal surface?
Proximal. The surfaces of teeth that normally lie adjacent to another tooth. Proximal includes both mesial and distal, such as when referring to the proximal surfaces of teeth.
What is the front of the tooth called?
Incisors. The incisors are the eight teeth that are most visible in the front of the mouth. There are eight incisors in total, four on the top and four on the bottom. These are often called your front teeth.
How many surfaces are there in a tooth?
To begin with, there are five surfaces in each tooth. The surfaces depend on whether the tooth is positioned in the front or in the back. These surfaces include: A tooth has 2 proximal surfaces. One is oriented towards the middle of the dental arch and the other is oriented facing away from the middle of the dental arch.
What is the lingual surface of teeth?
The lingual surface refers to the tongue-side of your teeth and is also generally smooth. The exception to this is the upper molars that may also have lingual grooves that end in a pit. Some of your upper front teeth may also have some lingual pits. Advertisement.
What is the number of wisdom teeth?
The wisdom tooth is usually counted as tooth number 1. The mouth is divided into four quadrants, known as upper left, upper right, lower left and lower right. The teeth in our mouth are also separated into the back and the front. At the back area, known as posterior, the teeth consist of molars and pre=molars or bicuspids.
How many groups of teeth are there?
In order to understand more about tooth surfaces, it is first and foremost necessary to understand that teeth are broadly divided into three groups in order to identify the tooth as per its location in the mouth. These three broad groups include: Advertisement. Mandibular or maxillary: Each individual has two jaws.
What are the grooves on the occlusal surface?
All the molars and premolars have grooves and pits on the occlusal surfaces. Occlusal means biting. These biting surfaces also contain raised areas, known as tooth cusps. Canines are also referred to as cuspids because they are having one cusp each.
What is the difference between a mandibular and a maxillary?
Mandibular or maxillary: Each individual has two jaws. The maxillary refers to the upper jaw and the mandibular is the lower jaw. The teeth which are present in these jaws are referred to as being either mandibular teeth or maxillary teeth.
How many cusps are in a molar?
Molars are known to have 4 to 5 cusps each. Cusps of your molars and premolars surround the grooves and pits present on these teeth. Coming to the incisal surfaces, these are the biting surfaces of your front teeth and may also have a hint of cusp development.
Which teeth share the mesial surface?
The only teeth that share their mesial surfaces are the maxillary and the mandibular central incisors.
What is the term for the surface of the tooth that is towards or adjacent to the lips?
The surface of the tooth that is towards or adjacent to the lips. The term labial surface is usually used for surfaces of incisors and canines that are present just adjacent to the lips.
What is the lingual surface of a tooth?
Lingual Surface. The surface of the tooth that is towards or adjacent to the tongue. The term lingual surface is used for the surface of a mandibular tooth (anterior or posterior) that is present immediately adjacent to the tongue.
What is buccal surface?
The term buccal surface is designated for the surfaces of premolars and molars that are immediately adjacent to the cheek.
What is the universal system of dentition?
There are several types of designation/identification systems, but the most common is the Universal System where the permanent dentition is numbered from 1-32 beginning with the maxillary right third molar. Distal – The surface that is away from the midline of the face.
What is the mesial surface?
Mesial – The surface that is closest to the midline of the face. Occlusal – The chewing surface of posterior teeth. Proximal – Tooth surfaces that are next to each other (i.e., distal of lateral incisor and mesial of canine). Figure 6. Surfaces of the Teeth.
Which surface of the tooth faces away from the midline?
The distal surface (away from the midline) contacts the tooth immediately posterior to it (distal to it) in the arch. Following the curvature of the dental arch , it is the tooth surface that faces away from the midline (median line). With deciduous second molars and permanent third molars, it is that surface which faces posteriorly in the arch.
What is the axial surface of a tooth?
The axial surface is any surface of a tooth that is parallel to the long axis of the tooth. The long axis is an imaginary straight line passing through the crown and root of the tooth. The facial, lingual, mesial, and distal are all axial surfaces.
What is the occlusal surface?
Occlusal. The occlusal surface is the broad chewing surface found on posterior teeth (bicuspids and molars). The occlusal surface faces toward and contacts the teeth of the opposite jaw.
