The numbers 1-2 are part of the standard Gracey series for anterior teeth, but in many clinical contexts focused on posterior teeth, 11-12 (buccal/lingual) and 13-14 or 16-17 (distal) are emphasized. However, strictly speaking, 1-2 is a Gracey. Given the key, the distinction is often made based on standard kits.

Public Health DentistryDental plaque is a bacterial biofilm that forms on the teeth and is a common factor in the development of both dental caries and periodontal disease. While fluoride in drinking water can help prevent dental caries, it is not directly related to periodontal disease. Nutritional disturbances can affect the overall health of the individual but are not the sole cause of either condition. Disturbed occlusion may be a risk factor for certain dental issues but is not universally common to both diseases.

Given the mobile anterior teeth (Grade I) and the difficulty of a Class I RPD against a lower CD (Combination Syndrome risk), extraction and dual complete dentures is often the most stable conventional plan.

NEETMDSFor diagnosing proximal caries in a deciduous molar, especially when the extent of decay needs assessment, a periapical (IOPA) radiograph is the standard and first line of investigation. This imaging technique allows visualization of the interproximal surface and the pulp status, which is crucial for treatment planning. Electric pulp testing, thermal testing, and test cavities are typically used to assess pulp vitality in more complex cases or when the diagnosis is uncertain, not as a primary diagnostic tool for proximal caries.

General Medicine
Adrenaline (epinephrine) is a sympathomimetic agent that causes bronchodilatation. It is used to relieve bronchospasm in anaphylactic shock reactions.
Histamine, kinins and prostaglandins, such as prostaglandin E2, are inflammatory mediators. In response to allergic stimuli, inflammatory mediators may cause bronchoconstrictions.
Guaifenesin is an expectorant preparation that increases bronchial secretions to promote the expulsion of the mucus coughed up.

Physiology
Answer: 2) Decreases peripheral vascular resistance
Explanation: Thyroid hormones cause vasodilatation in several vascular beds, which decreases peripheral vascular resistance. This, along with increased cardiac output, leads to an overall increase in systolic blood pressure despite the diastolic BP possibly decreasing due to reduced resistance.

Adrenaline (Epinephrine) acts on alpha-adrenergic receptors to cause potent vasoconstriction, effectively reducing blood flow to the extraction site to control hemorrhage.

Vitamin K is a crucial cofactor in the carboxylation of glutamate residues in the synthesis of prothrombin (factor II), which is essential for its activity. Vitamin K deficiency can lead to decreased levels of factor II, resulting in a bleeding tendency known as hypoprothrombinemia.

OrthodonticsA high FMA angle indicates a vertical growth pattern, which is associated with a poorer prognosis for Class II correction due to increased difficulty in achieving stable results.
