1. Dental caries investigation: This investigation involves examining the teeth for signs of dental decay or cavities. It may include visual inspection, probing with dental instruments, and the use of dental X-rays to identify the extent and location of any decay.
2. Periodontal examination: This investigation focuses on assessing the health of the gums and supporting structures of the teeth. It includes measuring the depth of gum pockets, assessing gum bleeding, and evaluating the level of attachment between the gums and teeth. It helps in diagnosing and monitoring conditions like gingivitis and periodontitis.
3. Oral cancer screening: This investigation involves a thorough examination of the oral cavity, including the lips, tongue, cheeks, and throat, to detect any signs of oral cancer. It may include visual inspection, palpation of the oral tissues, and the use of special screening devices or tests.
4. Bite analysis: This investigation evaluates the alignment and function of the teeth and jaws. It includes assessing the occlusion (bite) to identify any malocclusions, such as overbite, underbite, or crossbite. It may involve taking dental impressions, X-rays, and using diagnostic tools like articulators to analyze the bite.
5. Temporomandibular joint (TMJ) examination: This investigation focuses on evaluating the health and function of the TMJ, which connects the jawbone to the skull. It includes assessing jaw movement, checking for joint sounds or clicking, and evaluating any signs of TMJ disorders, such as pain, limited jaw movement, or muscle tenderness. It may involve palpation, X-rays, and specialized imaging techniques like MRI or CT scans.
