Dentistry: Dental & Oral Health Quiz

The pulp cavity of a tooth is a direct pathway to the cardiovascular system and the heart. This is because the pulp cavity contains blood vessels and nerves that supply the tooth with nutrients and oxygen. If bacteria or infection enters the pulp cavity, it can spread to the bloodstream and potentially affect the cardiovascular system, including the heart. Therefore, it is important to maintain good oral hygiene and seek dental treatment if any issues arise to prevent complications in the cardiovascular system.

The maximum amount of time the ultrasonic scaler and polisher can stay on a tooth is 10-15 seconds. This time frame allows for effective cleaning and polishing without causing any damage or discomfort to the tooth or surrounding tissues.

Squamous-cell carcinoma is the correct answer because it is a type of oral tumor that is most commonly seen in cats. Melanosarcoma and fibrosarcoma are also types of tumors, but they are not specifically associated with the oral region in cats. Epulis is a benign tumor that can occur in the mouth, but it is not as common as squamous-cell carcinoma. Therefore, squamous-cell carcinoma is the most likely oral tumor to be seen in cats.

Canines are designed for gripping and holding objects. They have long, pointed shape and are positioned in the front of the mouth, which allows them to firmly grasp and hold onto things. This is particularly useful for activities such as tearing apart meat or holding onto prey. Canines are not primarily used for shearing and grinding, as that is the function of molars and premolars. Grooming and gnawing are also not the main purposes of canines.

Mesaticephalic is the most common skull type. Mesaticephalic skulls have a medium width and length, making them balanced and proportional. This type of skull is commonly found in many mammal species, including humans. Brachycephalic skulls are wider than they are long, while dolichocephalic skulls are longer than they are wide. However, neither of these skull types are as common as mesaticephalic skulls.

Enzymes are said to aid in the destruction of bacteria in the mouth. Enzymes are proteins that act as catalysts, speeding up chemical reactions in the body. In toothpaste, enzymes help break down food particles and plaque, which are a breeding ground for bacteria. By breaking down these substances, enzymes help eliminate bacteria and promote oral hygiene.

Canine molars typically erupt between the ages of 3.5 to 7 months in dogs. This is the time period when these teeth start to emerge from the gums and become visible in the mouth. The eruption of canine molars is an important milestone in a dog's dental development, as these teeth play a crucial role in chewing and grinding food. It is important for pet owners to be aware of this timeline to ensure proper dental care and monitor the growth and development of their dog's teeth.

The correct answer is "Calculus" because "C" is commonly used as the abbreviation for the subject of Calculus. Calculus is a branch of mathematics that deals with the study of change and motion, and it is often represented by the letter "C" in mathematical notations and equations.

Feline deciduous premolars erupt at 3-6 weeks, while permanent premolars erupt at 4-6 months. This means that kittens will start to develop their deciduous premolars at around 3-6 weeks of age, and these teeth will be replaced by permanent premolars at around 4-6 months of age. This information is sourced from page 515 of Sirois.

Deciduous teeth, also known as baby teeth or primary teeth, typically start to erupt around 6 months of age and should be completely gone by the age of 6 years. These teeth are gradually replaced by permanent teeth. Therefore, the correct answer is 6 months.

The correct answer is UPM3 LM1, UPM3 and LM1. This answer suggests that feline carnassial teeth are located in both the upper and lower jaw, specifically in the third upper premolar (UPM3) and the first lower molar (LM1). These teeth are important for slicing and shearing meat, which is a characteristic feature of carnivorous animals like felines.

The small bump located just caudal to the upper incisors and aids in detecting pheromones is called the incisive papilla. This structure is found in the roof of the mouth and contains specialized taste buds that help in detecting chemical signals, including pheromones. The incisive papilla plays a role in the sense of taste and is particularly important in animals for detecting social and reproductive cues through pheromones.

In stage 2 of periodontal disease in dogs, pockets can be up to 5 mm in depth. These pockets are spaces that form between the gum tissue and the teeth, and they can harbor bacteria and plaque, leading to further damage to the teeth and gums. Regular dental care and professional cleanings are important to prevent the progression of periodontal disease and maintain oral health in dogs.

Gram negative, anaerobic rods.

The equine dental formula describes the number and types of teeth in a horse's mouth. The correct answer, 2x ( I 3/3, C 1/1, PM 3-4/3, M 3/3 ), indicates that there are two sets of teeth, with three incisors, one canine, three to four premolars, and three molars on each side of the upper and lower jaws. This dental formula is specific to horses and helps to identify and classify their teeth.

The feline dental formula consists of two sets of teeth. The formula indicates the number and types of teeth in each quadrant of the mouth. The correct answer, 2x ( I 3/3, C 1/1, PM 3/2, M 1/1 ), means that in each quadrant, there are 3 incisors, 1 canine, 3 premolars, and 2 molars. This formula represents the dental pattern of a cat, with slight variations in the number of premolars compared to other animals.

The abbreviation MGL stands for Mucogingival line. The mucogingival line refers to the line of demarcation between the attached gingiva and the alveolar mucosa in the oral cavity. It is an important anatomical landmark used in dentistry to assess the health and stability of the gingival tissues.

Anodontia is a condition where a person is missing all of their teeth. This can be caused by genetic factors or certain medical conditions. People with anodontia may require dental prosthetics or implants to restore their ability to eat and speak properly.

Grade 4 dentals should be pre-treated with antibiotics 24-48 hours before their procedure. This time frame allows the antibiotics to start working and reach their peak effectiveness before the dental procedure takes place. Administering the antibiotics within this window helps to prevent infection and reduce the risk of complications during and after the procedure.

Feline molars typically start to erupt at around 4-6 months of age. This is the period when the molars begin to emerge from the gums and become visible in the mouth. The eruption of molars is an important milestone in a cat's dental development, as these teeth are crucial for chewing and grinding food. It is essential for cat owners to be aware of this timeline to ensure proper dental care and monitor the growth and development of their cat's teeth.

The Triadan system is used for dental records in veterinary medicine. It assigns a unique number to each tooth in the mouth, making it easier to identify and track dental issues in animals. This system is widely used by veterinarians to maintain accurate dental records and provide effective dental care for animals.

Proper oral care for pets can significantly increase their lifespan by an average of 2 years. This includes regular brushing, dental check-ups, and professional cleanings. Neglecting oral hygiene can lead to various dental diseases and infections, which can have a detrimental effect on the overall health of pets. Therefore, it is crucial to prioritize oral care to ensure a longer and healthier life for our furry companions.

Melanosarcoma is the correct answer because it is a type of tumor that affects the melanocytes, which are the cells responsible for producing pigment in the skin and other tissues. This tumor is known to grow rapidly and commonly affects older dogs, particularly those over 10 years of age. Melanosarcoma is a malignant tumor that can occur in various locations, including the oral cavity.

Horses have a variable number of permanent teeth, with the average range being between 40 and 42. This means that some horses may have 40 permanent teeth, while others may have 42. The exact number can vary depending on factors such as age, breed, and individual variation.

Tooth B is classified as hypsodont.

Rodents have hypsodont teeth. Carnivores, pigs, and humans have brachydont teeth.

The correct answer is "Mobility" because "M" is commonly used as an abbreviation for this term. Mobility refers to the ability to move or be moved freely and easily, and it can be applied in various contexts such as transportation, technology, and physical movement.

85% of animals have some form of dental disease. This high percentage suggests that dental disease is a common issue among animals. It highlights the importance of dental care for pets and the need for regular check-ups and maintenance to prevent or treat dental problems. Dental disease can cause pain, discomfort, and other health issues in animals, so it is crucial to prioritize their dental health to ensure their overall well-being.

Hypodontia refers to the condition where some teeth are missing. It is a developmental anomaly that can affect both primary and permanent teeth. The missing teeth can be a result of genetic factors or environmental factors during tooth development. Hypodontia can range from a single missing tooth to multiple missing teeth. It can have functional and aesthetic implications, and treatment options may include orthodontics, dental implants, or prosthetic replacements.

The correct answer is 0-1 mm because a healthy sulus depth in a cat is typically very shallow, ranging from 0 to 1 mm. This measurement refers to the depth of the furrow or groove on the surface of the cat's tongue. A shallow sulus depth indicates good oral health and proper functioning of the tongue for grooming and eating.

Animals with two sets of teeth are referred to as diphydont. This term is used to describe the process of tooth replacement in animals, where they have two separate sets of teeth during their lifetime. The first set, known as deciduous or milk teeth, is replaced by a second set of permanent teeth as the animal grows and develops. This process is commonly observed in mammals, including humans, as well as some reptiles.

Fibrosarcoma is the correct answer because it is a type of tumor that is firm, flat, and ulcerated. It is also known to occur in the oral cavity of larger dogs and is generally slow to metastasize, meaning it does not spread quickly to other parts of the body. Melanosarcoma is a type of tumor that involves melanin-producing cells, Squamous-cell carcinoma is a type of cancer that affects the squamous cells, and Epulis refers to a benign tumor of the gum tissue. Therefore, Fibrosarcoma is the most fitting explanation for the given characteristics.

When performing a dental procedure, it is important to wear the appropriate personal protective equipment (PPE) to ensure safety and prevent the spread of infection. Safety glasses protect the eyes from any potential splashes or debris. Gloves are essential to protect both the dental professional and the patient from cross-contamination. A mask is necessary to prevent the inhalation of airborne particles or droplets. Therefore, safety glasses, gloves, and a mask should be worn while performing a dental procedure.

The correct answer is 4-10 weeks, 3.5-6 months. Canine deciduous premolars typically erupt between 4-10 weeks of age in puppies, while permanent premolars erupt between 3.5-6 months of age. This information can be found on page 515 of the Sirois textbook.

The correct answer is 306 Fx. In the Triadan system, each tooth is assigned a unique number. The 2nd lower left premolar is numbered 306. The abbreviation "Fx" is commonly used in dental charting to indicate a fracture. Therefore, the correct way to chart that the 2nd lower left premolar is fractured is by using the number 306 followed by the abbreviation Fx.

Tooth A is classified as brachyodont because it has low, rounded cusps and a limited amount of enamel. Brachyodont teeth are typically found in omnivorous and herbivorous mammals, and they are adapted for grinding and crushing plant material. This type of tooth structure is different from hypsodont teeth, which have high, elongated cusps and a large amount of enamel, and are typically found in grazing herbivores.

In order to adequately and safely look at the mouth and surrounding tissues, the patient should be under general anesthesia.

The periodontum refers to the supporting structures of the tooth, including the gingiva (gums), cementum (covering the root of the tooth), periodontal ligament (connects the tooth to the surrounding bone), and alveolar bone (the bone that holds the tooth socket). These structures are essential for maintaining the stability and health of the tooth within the jaw. The other options listed, such as dentin, pulp cavity, crown, enamel, and tongue, are not part of the periodontum.

After applying fluoride, it is important to blow it out. This is because blowing out the fluoride helps to remove any excess or residual fluoride from the mouth. It ensures that the fluoride does not remain in the mouth for an extended period of time, which could potentially lead to negative effects such as tooth discoloration or enamel damage.

Feline deciduous incisors are the first set of teeth that kittens develop. They begin to erupt at around 2-3 weeks of age. These deciduous incisors are eventually replaced by permanent incisors, which start to erupt at around 3-4 months of age. This process of tooth eruption is a normal part of a kitten's development.

Oligodontia refers to a condition where a person is missing most of their teeth. This can be caused by genetic factors or developmental issues. The term "oligo" means few or little, and "dontia" refers to teeth. Therefore, oligodontia accurately describes the condition of missing most teeth.

Wry mouth is a condition where one side of the face appears to be pulled or twisted due to uneven growth of the skull. This uneven growth causes an imbalance in the facial muscles, resulting in the characteristic appearance of wry mouth. The term "wry" refers to the twisted or distorted appearance of the mouth and face. The condition can be congenital or acquired, and it may require medical intervention or corrective surgery to improve the symmetry and function of the affected side of the face.

A sickle scaler is a dental instrument that has a sharp tip with a triangular cross-section. It is specifically designed to remove tartar buildup from the crown of the tooth. The sharp tip allows for precise and effective scaling, while the triangular shape helps to access hard-to-reach areas. This instrument is commonly used by dental professionals during routine dental cleanings to maintain oral hygiene and prevent dental issues.

Incisors are sharp, chisel-like teeth located at the front of the mouth. They are used for grooming and gnawing. Grooming involves cleaning and maintaining the fur or feathers, and incisors help in removing dirt and parasites from the body. Gnawing refers to the act of biting and chewing on hard materials like wood or bones. Incisors are well-suited for this purpose due to their sharp edges, allowing animals to break down and consume tough substances.

The correct answer is 3-5 weeks, 3-5 months. This means that the deciduous incisors in canines typically start to erupt at around 3-5 weeks of age, and the permanent incisors will then begin to erupt at around 3-5 months of age. This information can be found on page 515 of the Sirois textbook.

The statement is true because cleaning the inside surfaces of the teeth (lingual and palatal surfaces) is not necessary. This is because these surfaces are in contact with the tongue and palate, which naturally help to keep them clean. The main focus of oral hygiene should be on cleaning the outer surfaces (buccal surfaces) and the chewing surfaces of the teeth.

Bacteria in the mouth can enter the bloodstream through gum disease or dental procedures, leading to infections in various organs. The heart, liver, and kidneys are particularly vulnerable as they receive a significant blood supply. Bacterial infections in these organs can cause serious complications such as endocarditis, liver abscesses, and kidney infections. Therefore, it is essential to maintain good oral hygiene to prevent the entry of bacteria into the bloodstream and minimize the risk of affecting these vital organs.

The term CEJ stands for Cemento-enamel junction, which refers to the area where the cementum (outer layer of the tooth root) and enamel (outer layer of the tooth crown) meet. This junction plays a crucial role in tooth structure and is important for maintaining the integrity of the tooth.
