A class ___ malocclusion is when the mandible is shorter than the maxilla.
Explanation
Class II malocclusion refers to a dental condition where the mandible (lower jaw) is shorter than the maxilla (upper jaw). In this condition, the upper teeth are positioned further forward than the lower teeth, leading to an overbite. This can cause various dental and facial problems, including difficulty in chewing, speech issues, and aesthetic concerns. Treatment for Class II malocclusion may involve orthodontic appliances, such as braces or headgear, to correct the alignment of the teeth and jaws.Rate this question:

A class ___ malocclusion is when the maxilla is shorter than the mandible.
Explanation
Class III malocclusion, also known as prognathism or underbite, is a dental condition where the lower jaw (mandible) protrudes forward, causing the lower teeth to overlap the upper teeth. This is in contrast to a normal bite where the upper jaw (maxilla) is slightly longer than the lower jaw. Therefore, in a Class III malocclusion, the maxilla is shorter than the mandible.Rate this question:

Premolars and molars are for
-
Shearing and grinding
-
Gripping and holding
-
Grooming and gnawing
Correct Answer
A. Shearing and grindingExplanation
Premolars and molars are types of teeth found in mammals, including humans. They are located towards the back of the mouth and have a flat surface with multiple cusps. These teeth are specifically designed for shearing and grinding food. The flat surface and cusps help in breaking down food into smaller pieces, making it easier to swallow and digest. This is why premolars and molars are responsible for the chewing process, playing a crucial role in the overall digestion of food.Rate this question:

What is the hardest substance of the body?
Correct Answer
EnamelExplanation
Enamel is the hardest substance of the body. It is the outermost layer of the teeth and provides protection against wear and tear. Enamel is composed of minerals, mainly hydroxyapatite, which makes it highly resistant to acid and bacteria. Its hardness allows it to withstand the forces of chewing and biting. Enamel is even harder than bone and dentin, making it the strongest substance in the body.Rate this question:

What cells from the pulp cavity continue to manufacture dentin throughout the life of a tooth?
Correct Answer
OdontoblastsExplanation
Odontoblasts are cells found in the pulp cavity of a tooth that continue to manufacture dentin throughout the life of the tooth. Dentin is a hard, mineralized tissue that makes up the majority of the tooth structure. Odontoblasts are responsible for the production of dentin, which helps to protect the underlying pulp and maintain the structural integrity of the tooth. As the tooth ages and undergoes wear and tear, odontoblasts continuously produce dentin to repair and strengthen the tooth. This ongoing dentin production by odontoblasts ensures the longevity and functionality of the tooth throughout a person's life.Rate this question:
