Necessary in all cases of all treatments intended to be performed. Considered as standard operating procedure.

Explanation
Essential Diagnostic Records are necessary in all cases of all treatments intended to be performed. They are considered as standard operating procedure because they provide crucial information about a patient's condition, including medical history, test results, and any other relevant diagnostic information. These records help healthcare professionals make informed decisions about the appropriate treatment plan for the patient. Without these essential diagnostic records, it would be difficult to ensure the safety and effectiveness of the treatment being performed.

A.

Radiograph
B.

Study cast
C.

Medical and dental history
D.

Intraoral photographs

Correct Answer
B. Study cast

Explanation
Study casts, also known as dental models, are three-dimensional replicas of a patient's teeth and oral structures. They are created by taking impressions of the patient's teeth and pouring a dental stone or plaster into the mold. Study casts are commonly used in dentistry for diagnosis, treatment planning, and evaluation of treatment outcomes. They provide a detailed and accurate representation of the patient's dentition, allowing dentists to examine the teeth from different angles and identify any abnormalities or issues that may not be easily visible during a clinical examination. Therefore, study casts can reveal aspects of the dentition that may be overlooked during a clinical exam.

Lips are able to close over dentition in a relaxed position.

A.

Incompetent lips
B.

Relaxed lips
C.

Protruded lips
D.

Competent lips

Correct Answer
D. Competent lips

Explanation
Competent lips refer to the ability of the lips to close over the teeth properly and maintain a relaxed position. This means that the lips are able to effectively seal the oral cavity, allowing for proper speech, swallowing, and preventing air leakage during breathing. In contrast, incompetent lips would not be able to close over the teeth properly, leading to difficulties in speech articulation and increased risk of air escape. Therefore, the given correct answer suggests that lips that can close over dentition in a relaxed position are considered competent.
