Pressure and temperature responses are elicited by all of the following EXCEPT one. Which one is the EXCEPTION?

Blood vessels traveling through the apical foramen support nerves and odontoblasts because the blood supply enables delivery of essential nutrients as well as removal of harmful products.

Each of the following teeth frequently has two roots EXCEPT one. Which one is the EXCEPTION?

Maxillary molar root trifurcations are located on each of the following surfaces EXCEPT one. Which one is the EXCEPTION?

Orthodontics requires a sustained pressure to move teeth to a new location. Osteoblasts respond to the new location by forming new bone.

Teeth with curved roots afford resistance to apical and distal forces but are vulnerable to occlusal forces. Roots with triangular cross section are particularly vulnerable to lateral displacement.

Root canal therapy in third molars is considered very unpredictable because the tooth is located so far distally in the mouth.

Mandibular premolars typically have two pulp canals. Maxillary first premolars are more likely than maxillary second premolars to have two pulp canals.

During hypercementosis, excess cementum is deposited

Cementum formed during hypercementosis is different from the cementum lining the root because this newly formed product can continue to grow and add on to itself.

Each of the following root characteristics provides significant resistance to displacement from traumatic forces EXCEPT one. Which one is the EXCEPTION?

A slight amount of mobility is not considered normal. Orthodontics can help with bone remodeling that can prevent even slight tooth mobility.

Each of the following is a characteristic of the periodontal ligament EXCEPT one. Which one is the EXCEPTION?

A patient who has sensitivity in the mandibular anterior area due to abrasion is interested in having her teeth bleached. Which factor could contribute to her sensitivity?

The figure below shows a mesial view (A) and a distal view (B) of a linguobuccal section. Identify the tooth.

Which of the following best describes the root canal opening(s) in the figure below?

An 11-year-old boy, Ronald, has an overjet and is being treated by an orthodontist. At a routine appointment, Ronald mentions that he feels some pressure in the area of his maxillary anterior incisors and asks if this is unusual. The orthodontist examines Ronald, makes some adjustments to his appliance, and reviews his radiographs. He informs Ronald that he is pleased with the movement of his teeth and that he may feel occasional pressure throughout treatment. In Ronald's case, each of the following radiographic findings is considered normal during orthodontic treatment EXCEPT one. Which one is the EXCEPTION?

Which factors contribute to forming new bone (select all that apply)?

Pain within the root (root pain) can be elicited by which of the following (select all that apply)?

Which of the following travel through the apical foramen (select all that apply)?

Dentin tubules can carry a stimulus from the root surface to the nerves in the pulp canal.

The cementum covering the root is thick and smooth when first formed.

Root pain always means that dental caries is present.

If there are two pulp canals in a root, there could be one or two openings in the root.

Mandibular second molars often have two canals in each root.
