Public Health DentistryThe mode is the value that appears most frequently in a data set. In the given set of DMFS index values (2, 3, 5, 5, 6, 7, 7, 7, 12, and 13), the number 7 appears three times, which is more frequent than any other number.

Resin teeth are capable of forming chemical bonds with commonly used denture base resins, which allows for a stronger and more durable bond compared to porcelain teeth.

Oral SurgeryThe middle superior alveolar nerve (MSA) is one of the branches of the maxillary nerve that innervates the buccal gingival of the maxillary teeth, including the second premolar. The anterior palatine nerve innervates the palatal aspect, while the buccal nerve innervates the buccal mucosa and the anterior part of the palate.

Pulsus paradoxus is an exaggerated decrease in systolic blood pressure during inspiration, which can occur in patients with airflow obstruction conditions such as emphysema and asthma. These conditions can lead to increased intrathoracic pressure swings during respiration, which affects the cardiac output and arterial pulse amplitude.

SOLUTION Light and continuous
Use of continuous light force is recommended to be applied for adult group of patient rather than intermittent force as applied by removable appliance. This is because continuous forces are expected to bring about direct resorption of the root socket. They should hence not occlude more than a small percentage of blood vessels with in the periodontal ligament, not substantially interfere with their nutritional supply and little interference
with normal biologic functioning. In adult due to heavy force teeth may devitalize because the opening into the tooth (apical foramen) is smaller and blood vessels can be easily disrupted.

The retrodiscal tissue, located behind the articular disc of the temporomandibular joint (TMJ), is highly vascularized and innervated. In contrast, the articular disc itself is largely avascular and aneural in its central portion.

Oral PathologyRadiographic resolution of a periapical lesion (an area of bone loss around the tooth root caused by infection) after proper root canal treatment typically takes time because it involves the biological process of new bone formation to replace the damaged area. This healing process is a gradual one, and while clinical symptoms resolve quickly, visible changes on an X-ray (radiographic resolution) can take several months to become apparent. The 6-12 month timeframe is the established period for significant or complete radiographic evidence of healing in most cases. A longer follow-up period may be needed in some instances.

General MedicineThe pacemaker of the heart is the SA (sinoatrial) node. Located in the right atrium, it generates spontaneous electrical impulses at 60-100 beats per minute, initiating each heartbeat. It has the highest intrinsic firing rate, making it the natural pacemaker.
