Which assessment method can be used to indicate the presence of a periodontal pocket?

The use of a Basic Periodontal Examination (BPE) probe is specifically designed to assess the health of periodontal tissues and to identify the presence of periodontal pockets. This assessment method involves measuring the depth of the gingival sulcus around each tooth, providing critical information regarding the condition of the periodontium. A periodontal pocket is indicated when these measurements exceed normal values, suggesting inflammation and possible periodontal disease.

In contrast, bitewing radiographs are useful for visualizing interproximal caries and assessing bone levels but do not provide direct information about soft tissue health or pocket depth. Disclosing tablets are primarily used to identify plaque accumulation on the teeth, which is beneficial for educational purposes and improving oral hygiene but do not assess pocket depth. Transillumination is a technique used to detect dental caries or cracks in teeth by shining light through the tooth structure, but it does not provide information regarding periodontal pocketing. Thus, the BPE probe is the most relevant and effective method for assessing periodontal pocket presence.
