Definition and Core Components

Oral health assessment is a multi-faceted process that encompasses several key elements:

Visual Examination: Dentists or dental hygienists use specialized tools to inspect the teeth, gums, tongue, lips, and oral mucosa for any signs of disease, injury, or abnormality. This visual assessment includes checking for tooth decay, gum inflammation, oral ulcers, and any structural anomalies.
Palpation: This involves gently touching or pressing specific areas of the mouth to assess pain, tenderness, or swelling. Dentists may use their fingers or specialized instruments to palpate the gums, teeth, and temporomandibular joints.
X-ray Imaging: Radiographic examinations provide detailed images of the oral cavity, enabling dentists to identify caries not visible during a visual exam, evaluate tooth and root positions, and detect bone loss or cysts. Common X-ray types include periapical (focusing on individual teeth) and bitewing (showing multiple teeth).
Oral Cancer Screening: OHA includes a thorough examination for any signs of oral cancer, such as abnormal growths, ulcers, or lesions in the mouth, throat, or lips. This crucial step involves visual inspection, palpation, and sometimes specialized tests like oral brush biopsies.
Assessment of Oral Function: Evaluating an individual’s ability to chew, speak, and swallow is integral to OHA. Dentists may inquire about chewing efficiency, speech clarity, and any difficulties in swallowing.
