Dental Simulation Exam 3

In the case of a completely avulsed tooth, the dental assistant should instruct the patient to do the following: place the tooth in the patient's buccal vestibule or under the tongue to keep it moist, keep the tooth moist in milk or saline, and see the dentist immediately. However, scrubbing the tooth to remove any bacteria is not recommended as it can damage the delicate periodontal ligament cells on the tooth root surface and decrease the chances of successful re-implantation.

Crepitus is the correct answer because it refers to the grating sound heard within the temporomandibular joint in a patient with temporomandibular joint disorder. It is a common symptom of this disorder and is caused by the rubbing of the joint's surfaces against each other due to abnormalities in the joint structure or function. Hypomobility refers to reduced movement of the joint, myofacial dysfunction refers to muscle pain and dysfunction, and trismus refers to limited mouth opening, none of which specifically describe the grating sound.

When placing sealants, if areas of enamel are inadvertently etched, the enamel will undergo a process called remineralization. This means that minerals such as calcium and phosphate will be deposited back into the etched areas, helping to repair and strengthen the enamel. As a result, the enamel will not remain permanently etched, be sensitive, or be more subject to decay.

Attrition refers to the natural wearing down of teeth due to tooth-tooth contact during activities such as chewing, grinding, and clenching. On the other hand, abrasion refers to the wearing away of tooth structure caused by external forces such as improper toothbrushing technique, using abrasive toothpaste, or biting on hard objects. Therefore, the statement is true as it correctly differentiates between attrition and abrasion based on the causes of tooth wear.

Both antibacterials and xylitol provide protection from dental disease. Antibacterials help to kill or inhibit the growth of bacteria in the mouth, reducing the risk of dental infections and diseases. Xylitol, on the other hand, is a natural sweetener that has been shown to reduce the growth of harmful bacteria in the mouth and prevent tooth decay. Therefore, choosing both options A (antibacterials) and C (xylitol) would provide the best protection against dental disease.

The correct answer is "behind the tuberosity." When selecting an impression tray for a preliminary maxillary impression, it is important for the tray to extend posteriorly behind the tuberosity. The tuberosity is the bony prominence at the posterior end of the upper jaw, and extending the tray behind it ensures that the impression captures the entire maxillary arch accurately. This allows for a more precise fit of any prosthesis or restoration that may be required.

Before a periodontal dressing is placed, all sutures should be removed. This is because the periodontal dressing is applied to protect the surgical site and promote healing. If sutures are still present, they may interfere with the proper placement and adherence of the dressing. Therefore, all other conditions mentioned in the options, such as bleeding under control, thorough irrigation of the surgical site, and teeth and tissue free of excessive oral fluids, should exist before placing the periodontal dressing.

CAMBRA stands for Caries Management By Risk Assessment. This acronym refers to a methodology used to assess the risk of dental caries (tooth decay) in patients. It involves evaluating various risk factors, such as oral hygiene, diet, and previous dental history, to determine the likelihood of developing caries. This information is then used to develop personalized prevention and treatment plans for patients, with the goal of minimizing the risk of caries and promoting oral health.

The more common term for odontalgia is toothache. Odontalgia refers to the pain or discomfort in the tooth or teeth, which is commonly known as toothache. Dentures are artificial teeth, plaque is a sticky film that forms on teeth, and gingivitis is the inflammation of the gums. However, none of these terms specifically refer to the pain associated with tooth problems, making toothache the correct answer.

Nitrous oxide analgesia is not usually recommended for patients who have nasal congestion because nitrous oxide is administered through a mask that covers the nose. If a patient has nasal congestion, the mask may not fit properly, leading to inadequate administration of the analgesia. Additionally, nasal congestion can make it difficult for the patient to breathe properly, which can be exacerbated by the use of nitrous oxide. Therefore, it is advisable to avoid using nitrous oxide analgesia in patients with nasal congestion.

A pre-prepared tray setup is beneficial because it allows for the assembly of specific procedures. This means that all the necessary instruments and tools needed for a particular procedure can be organized and easily accessible in one tray. This saves time and effort as healthcare professionals do not have to search for individual instruments or sterilize them separately. Additionally, having a pre-prepared tray setup reduces the chances of instrument breakage as the instruments are stored and transported in a secure and organized manner.

The statement is true because questionnaires, interviews, and a combination of questionnaires and interviews are indeed three ways to obtain a medical or dental history. Questionnaires involve written forms that patients fill out with their medical information. Interviews involve direct conversations between healthcare providers and patients to gather their medical history. Combining questionnaires and interviews allows for a more comprehensive approach to gather accurate medical or dental history. Therefore, the given answer is true.

Pit and fissure sealants should be placed after the eruption of the entire occlusal surface in order to be most effective. This is because the sealants are used to protect the deep grooves and fissures on the chewing surfaces of the teeth, which are more susceptible to decay. By placing the sealants after the eruption of the entire occlusal surface, it ensures that all the grooves and fissures are sealed, providing maximum protection against decay. Placing sealants prior to eruption or permanent dentition, after proximal surfaces are carious, after placement of restorations, or after all permanent teeth are erupted would not be as effective in preventing decay in the deep grooves and fissures.

The correct answer is "absence of breathing and pulse." This is because when a person experiences cardiac arrest, their heart stops beating and they stop breathing. Therefore, the absence of breathing and pulse are key signs indicating that cardiac arrest has occurred. The other symptoms mentioned, such as coughing and seizures, may also occur during cardiac arrest but are not as specific or definitive as the absence of breathing and pulse.

The first thing to do when a patient has collapsed is to establish their level of responsiveness. This is important to determine if the patient is conscious or unconscious, and it helps guide further actions and interventions. By assessing their responsiveness, healthcare providers can quickly identify the severity of the situation and decide on the appropriate course of action, such as calling for emergency assistance, establishing an airway, or administering oxygen.

Obtaining a dental history is important to assess the overall dental or periodontal conditions of a client. It helps in understanding the past and present oral health issues, such as cavities, gum disease, or previous dental treatments. By gathering information about the client's dental history, a dentist can identify any potential risks or problems and provide appropriate treatment or preventive measures. This includes evaluating the condition of teeth, gums, and supporting structures, as well as identifying any underlying issues that may affect dental health.

Zinc oxide-eugenol is most often used for temporary restorations. It is a material that has a sedative effect on the pulp, making it suitable for temporary use. It provides a good seal and has antimicrobial properties, which help in preventing further decay or infection. Additionally, zinc oxide-eugenol has a relatively low cost and is easy to manipulate, making it a popular choice for temporary restorations in dental procedures.

Die stone requires the smallest water/powder ratio compared to dental stone and dental plaster. Die stone is a type of gypsum product that is specifically designed for creating highly accurate and detailed dental models or dies. It has a higher density and strength compared to dental plaster and dental stone, which allows for precise reproduction of dental impressions. Due to its unique composition, die stone requires less water to form a workable mixture, resulting in a smaller water/powder ratio. This ensures that the die stone mixture has the ideal consistency for creating intricate dental models.

Plaque is most likely to accumulate in the proximal spaces of the dentition. Proximal spaces are the areas between adjacent teeth where they come into contact. These areas are difficult to clean with regular brushing and flossing, allowing plaque, which is a sticky film of bacteria, to accumulate. Plaque buildup in the proximal spaces can lead to tooth decay and gum disease if not properly removed through regular oral hygiene practices.

The assistant uses the air/water syringe primarily to keep the mirror clean. During tooth preparation, the mirror can become fogged or covered in debris, making it difficult for the dentist to see the operating area clearly. By using the air/water syringe, the assistant can spray a combination of air and water onto the mirror, effectively clearing away any fog or debris and ensuring that the mirror remains clean and provides a clear view for the dentist.

The primary caries refers to the initial stage of tooth decay that occurs on a surface that has not been previously affected. It is the first sign of decay and can be detected by the appearance of a white spot on the tooth surface. This stage of caries can be reversed through proper oral hygiene and fluoride treatments.

The correct answer is Ten years after the last dental appointment, or two years past the client's age of majority in the case of children. This means that dental records must be kept for a minimum of ten years after the last appointment for adult clients. For children, the records must be kept until two years after they reach the age of majority, which is the legal age when a person is considered an adult. This ensures that dental records are available for reference and potential future treatments.

During a maxillary anterior facial preparation, the evacuator tip is placed to the lingual of the tooth being prepared. This positioning allows for effective removal of saliva, water, and debris from the oral cavity during the procedure. Placing the evacuator tip to the lingual side ensures that it does not interfere with the dentist's access to the facial surface of the tooth being prepared, allowing for better visibility and control during the procedure.

Hypocalcification refers to a condition characterized by a deficiency in the mineral content of a calcified tissue, such as enamel. This means that there is a lower than normal amount of calcium present in the tissue, leading to a weakened or less dense structure. This can result in various problems, such as weakened enamel in teeth, making them more susceptible to decay and damage.

Establishing rapport in an interview involves being friendly and understanding towards the client. This means creating a comfortable and welcoming environment for the client, showing empathy and respect, and actively listening to their concerns. Building rapport helps to establish trust and openness, which can lead to better communication and cooperation between the interviewer and the client.

Hypoplasia refers to the incomplete or deficient development of an organ or tissue. It is characterized by the underdevelopment or reduced size of the affected structure. This condition can occur due to various factors such as genetic abnormalities, environmental factors, or disruptions in the normal growth and development process. Hypoplasia can affect different organs or tissues in the body, leading to functional impairments or abnormalities.

Cold sores caused by herpes virus type 1 are very contagious. The initial infection (primary herpes), which often occurs before adulthood, may be confused with a cold or flu and can cause painful lesions to erupt throughout the mouth. Cold sore blisters usually heal in a week by themselves. Over-the-counter topical anesthetics can provide some relief. Prescription antiviral drugs may reduce these kinds of viral infections.

Feeling nauseous is an example of a symptom. Symptoms are subjective experiences reported by the patient, such as pain, discomfort, or a change in bodily functions. They are often used to help diagnose a medical condition or disease. In this case, nausea is a symptom that can indicate various underlying causes, and further evaluation is needed to determine the specific diagnosis.

Wax is placed along the facial periphery of the max impression tray to obtain registration of the mucobuccal attachments. The mucobuccal attachments are the areas where the oral mucosa attaches to the underlying structures, such as the underlying bone or muscle. By placing wax along the facial periphery, it helps capture the accurate shape and position of these attachments, ensuring a more precise fit of the denture or restoration. This is important for achieving optimal function and aesthetics for the patient.

The #4 bur in a lowspeed handpiece is the most suitable combination for removing carious dentin from a cavity preparation. A lowspeed handpiece provides better control and precision, which is important when removing carious dentin. The #4 bur is designed specifically for caries removal, with its small size and rounded shape allowing for efficient removal without damaging healthy tooth structure. Using a highspeed handpiece or larger bur (such as the #56 or #330) may result in unnecessary removal of healthy dentin and potentially weaken the tooth structure. The #702 bur is typically used for finishing and polishing, not for caries removal.

Following a meal or snack, the bacteria in plaque release acids that attack tooth enamel. Repeated attacks can cause the enamel to weaken, eventually causing tooth decay. FYI - Microgenia is small or underdeveloped chin.

Tertiary caries is not a type of caries. The correct term is "secondary caries," which refers to the development of new cavities adjacent to existing dental restorations. Tertiary caries is not a recognized term in dentistry. Incipient caries refers to the earliest stage of tooth decay, while rampant caries refers to the rapid and widespread progression of tooth decay.

A dentist making a forecast of a probable course refers to predicting the outcome or future development of a dental condition. This is known as a prognosis. A prognosis helps the dentist to estimate the likely progression of the condition and guide the patient in making informed decisions about their dental health. It is different from a symptom, which is a sign or indication of a condition, and diagnosis, which is the identification of a specific condition based on symptoms and examination.

Drinking bottled water exclusively can be a problem. Check to see if it's fluoridated. If it doesn't say, call the company.

Clean between teeth daily with floss or an interdental cleaner. Decay–causing bacteria still linger between teeth where toothbrush bristles can’t reach. This helps remove plaque and food particles from between the teeth and under the gum line.

Primary teeth eruption typically follows a specific pattern. The maxillary first molars usually erupt before the maxillary canines. This is a normal sequence of eruption in primary teeth development.

Other signs include pain, tenderness, or numbness anywhere in the mouth or on the lips and difficulty chewing, swallowing, speaking or moving the jaw or tongue.

In four-handed dentistry, the concept involves the dentist and dental assistant working together as a team. During instrument transfer, the fingers that usually retrieve the instrument from the operator are the ring finger and pinky finger. These fingers provide stability and control while grasping the instrument, allowing for a smooth and efficient transfer between the dentist and dental assistant.

A complex caries affects 3 or more surfaces because it involves the destruction of tooth structure in multiple areas. This type of caries can extend into the dentin and affect the enamel, as well as spread across different surfaces of the tooth. On the other hand, a compound caries affects 2 surfaces. This means that it involves the destruction of tooth structure in two adjacent surfaces, such as the mesial and occlusal surfaces or the buccal and lingual surfaces.

The best way to prevent oral cancer is to avoid tobacco and alcohol use. Regular dental check-ups, including an examination of the entire mouth, are essential in the early detection of cancerous and pre-cancerous conditions.

Be careful when using water picks. They can drive bacteria back up into the gums, which can lead to it lodging in other parts of the body, such as the heart.

Brushing and water irrigation are both effective techniques for removing plaque. Brushing helps to physically remove plaque from the teeth and gums, while water irrigation uses a stream of water to flush away plaque and food particles from hard-to-reach areas. By combining these two techniques, plaque can be more effectively removed from the mouth. Flossing is also a recommended technique for plaque removal, but it is not mentioned in the correct answer. Mouthwash can be used as an additional step for oral hygiene, but it is not as effective at removing plaque as brushing and water irrigation.

Placing a cotton roll in the vestibule, opposite of the max second molar can help in controlling saliva from the parotid duct. The vestibule is the space between the cheeks or lips and the teeth or gums, and in this case, it refers to the area opposite the maxillary (upper) second molar. By placing the cotton roll in this specific location, it can absorb saliva and prevent it from interfering with dental procedures or causing discomfort to the patient.

Giving the client privacy and sitting at eye level is important during the interview process as it helps create a comfortable and respectful environment. By giving the client privacy, it ensures that they feel safe and are more likely to open up and share information. Sitting at eye level also demonstrates equality and shows that the interviewer values the client's perspective. This approach can lead to more honest and meaningful communication, allowing the interviewer to obtain specific and accurate information from the client.

The correct answer is "Commencing the interview, Establish rapport, Use questionnaire, Completing the interview". This sequence of techniques makes logical sense in the context of client interviews. First, the interview needs to be started or commenced. Then, it is important to establish rapport with the client to create a comfortable and open environment for communication. Next, a questionnaire can be used to gather specific information from the client. Finally, the interview is completed, indicating the end of the interview process.

There are three types of dentin. Dentin is a hard, calcified tissue that makes up the majority of a tooth. The three types of dentin are primary dentin, secondary dentin, and tertiary dentin. Primary dentin forms during tooth development, secondary dentin forms after the tooth has erupted, and tertiary dentin forms in response to injury or decay. Each type of dentin serves a different function in protecting and supporting the tooth structure.

This statement is incorrect. Hypertrophy refers to the increase in size of cells, while hyperplasia refers to the increase in the number of cells.

Incipient caries refers to the beginning stage of tooth decay that only affects the enamel. At this stage, the decay has not yet progressed to the dentin or deeper layers of the tooth. It is important to detect and treat incipient caries early to prevent further damage to the tooth structure.
