Q & A
What is the primary focus of the video?
-The video primarily focuses on introducing basic dental terminology, which is essential for individuals entering the dental workforce or those interested in the field of dentistry.
How does the orientation of the dental diagram provided in the video differ from our normal perspective?
-The dental diagram in the video is oriented such that the patient's right side is on the left side of the image and their left side is on the right side, which can be confusing at first but is a standard way to view dental anatomy.
What are the two main arches of the human dentition?
-The two main arches of the human dentition are the maxillary arch, which refers to the upper teeth connected to the maxilla or upper jaw bone, and the mandibular arch, which refers to the lower teeth connected to the mandible or lower jaw bone.
What are the functions of incisors and canines?
-Incisors are used for incising or slicing food and are important for aesthetics and phonetics. Canines are used for tearing and holding food and are also significant for aesthetics.
What is the term used for the teeth located at the back of the mouth?
-The teeth located at the back of the mouth are called molars, with the third molars commonly referred to as wisdom teeth. Together with the premolars, they are known as the posterior teeth.
How does the universal notation system for numbering teeth work?
-The universal notation system for numbering teeth starts at the upper left corner of the mouth (which is the third molar when viewed from the dental perspective) and proceeds in a clockwise manner, numbering each tooth until it forms a complete circle, covering all 32 teeth in the adult dentition.
What is the term used to describe the process of baby teeth coming into the mouth?
-The process of baby teeth coming into the mouth is called eruption.
What is the difference between primary and permanent dentition?
-Primary dentition refers to the baby teeth or the first set of teeth that typically start erupting around six months of age. Permanent dentition refers to the adult teeth that begin to erupt around six years of age and continue to develop until around 12 years of age, replacing the primary teeth.
What are the five surfaces of a tooth?
-The five surfaces of a tooth are the facial (or labial for anterior teeth), lingual, mesial, distal, and occlusal (or incisal for anterior teeth) surfaces.
What is the term for the outermost layer of a tooth?
-The outermost layer of a tooth is called the enamel.
What is the difference between gingivitis and periodontitis?
-Gingivitis is the inflammation of the gums that does not involve bone loss, whereas periodontitis is a more severe gum disease that does involve bone loss and is irreversible without surgical intervention.
What is the term used to describe the hard deposit of minerals coated with bacterial plaque that builds up on teeth?
-The hard deposit of minerals coated with bacterial plaque that builds up on teeth is called calculus or tartar.
