Dental Assistant Test

Critical instruments have a high risk of disease transmission and should be heat sterilized.

The statement is true because in the Universal Numbering System, the permanent teeth are indeed numbered from 1 to 32. This system is widely used by dentists and dental professionals to identify and refer to specific teeth in a standardized manner. Each tooth is assigned a unique number, starting from the upper right third molar (number 1) and moving clockwise around the mouth to end with the lower right third molar (number 32). This numbering system helps in accurate communication and documentation of dental procedures and treatments.

In a basic setup, all of the mentioned instruments are used. A mouth mirror is used to visualize the oral cavity, explorer is used to detect any dental caries or abnormalities, and cotton pliers are used to handle and place cotton rolls or other materials in the mouth. Therefore, all of the above instruments are essential in a basic setup.

The abbreviation for Buccal-occlusal is BO.

The inter-proximal space refers to the area between adjacent tooth surfaces. This space is commonly known as the space between teeth, where food particles and plaque tend to accumulate if not properly cleaned. It is important to clean this area thoroughly to maintain good oral hygiene and prevent dental issues such as cavities and gum disease. Therefore, the statement that the area between adjacent tooth surfaces is called the inter-proximal space is true.

The lingual surface refers to the surface of the tooth that is closest to the tongue. This surface is found on the inner side of the teeth, facing towards the tongue. It is important to distinguish this surface from the facial surface, which is the surface of the tooth that is closest to the cheeks or lips. The mesial surface refers to the surface of the tooth that is closest to the midline of the mouth, while the distal surface refers to the surface that is farthest from the midline.

The system used in dentistry to remove water and other debris is indeed called the oral evacuation system. This system consists of a suction device that helps to keep the patient's mouth dry and clean during dental procedures. It is an essential tool in maintaining a clear field of vision for the dentist and ensuring the patient's comfort.

According to the Universal Numbering System, tooth #7 and #10 are indeed classified as maxillary lateral incisors. This system is widely used by dentists to identify and label teeth in a consistent manner. In this system, the teeth in the upper jaw are numbered from 1 to 16, starting from the right side of the mouth and moving to the left. Tooth #7 and #10 correspond to the upper right and upper left lateral incisors respectively. Therefore, the statement is true.

The abbreviation for Mesioincisal is MI.

A palm-thumb grasp refers to the way an instrument is held in the palm of the hand, with the thumb being used to stabilize the instrument. This grip is similar to how one would hold a pen, where the instrument is securely held in the palm while the thumb provides stability.

The anterior teeth include the incisors and canines.

An abutment is a dental term that refers to the teeth on either side of a missing tooth. These teeth act as support or anchor for a dental prosthesis, such as a bridge or denture, that replaces the missing tooth. The abutment teeth are prepared to receive the prosthesis and provide stability and retention.

Hepatitis B is the most infectious bloodborne pathogen likely to be encountered in the dental workplace. This is because it is highly contagious and can be transmitted through contact with infected blood or bodily fluids. Dental professionals are at a higher risk of exposure to Hepatitis B due to the nature of their work, which involves handling sharp instruments and coming into contact with patients' blood. It is important for dental healthcare workers to follow strict infection control protocols, including vaccination against Hepatitis B, to prevent transmission of the virus.

The subsupine position refers to a patient position where the patient's head is lower than their heart. In this position, the patient is lying on their back with their head tilted downwards. This position is often used in medical procedures to facilitate blood flow and drainage from the head and neck area. It can also help with reducing swelling and pressure in certain medical conditions.

The excavator is an example of a hand-cutting instrument used in dentistry. It allows the dentist, dental hygienist, or dental assistant to remove decay manually from teeth for final restoration.

The dental degree DDS stands for Doctor of Dental Surgery. This degree is awarded to individuals who have completed a program in dentistry and have acquired the necessary knowledge and skills to practice as a dentist. The term "surgery" in the degree title refers to the fact that dentists are trained in performing various surgical procedures related to oral health.
