Final answer:
It is best to start with anterior images when taking periapical images because they are easier to capture, more comfortable for the patient, and allow for a systematic approach to radiography. Anterior teeth are generally more accessible and less sensitive, making it easier to place the film or sensor. Proper shielding and fast films are used to minimize radiation exposure to the patient.
Step-by-step explanation:
When taking periapical images, it is best to start with anterior images because anterior images are easier to capture than posterior images. This is because the anterior teeth, which include the eight incisors and four cuspids, are more accessible, have simpler anatomy, and require less intraoral placement intrusion for the patient. Therefore, capturing these images first is often more comfortable for the patient, which could help reduce movement and result in clearer images. Additionally, it allows for a more systematic approach to capturing full mouth radiographs, starting from the front and moving towards the back of the mouth.
Another consideration is patient comfort; the anterior teeth are generally less sensitive to pressure and can accommodate the film or digital sensor more easily compared to the posterior areas where the mouth is narrower. Starting with anterior images also allows the clinician to build confidence and cooperation with the patient before proceeding to the areas that may potentially cause more discomfort. Moreover, during the process of dental radiography, it's crucial to minimize unnecessary radiation exposure.
