Fluoride has a high tendency to react with the calcium hydroxyapatite Ca10(PO4)6(OH)2 in tooth enamel due to its high affinity to metals. [8] [10] It subsequently replaces the hydroxide group in hydroxyapatite to precipitate calcium fluorapatite Ca5(PO4)3)F. [8] These fluorapatite precipitations scavenge excess phosphate and calcium in the saliva to form a supersaturated solution for ...
Dental fluorosis appears as a range of visual changes in enamel [4] causing degrees of intrinsic tooth discoloration, and, in some cases, physical damage to the teeth. The severity of the condition is dependent on the dose, duration, and age of the individual during the exposure. [ 1 ]
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Under the proposal, the ICD-9-CM code sets would be replaced with the ICD-10-CM code sets, effective October 1, 2013. On April 17, 2012, the Department of Health and Human Services (HHS) published a proposed rule that would delay the compliance date for the ICD-10-CM and PCS by 12 months-from October 1, 2013, to October 1, 2014.

According to this theory, when the exposed dentine surface is subjected to thermal, chemical, tactile or evaporative stimuli, the flow of the fluid within the tubules will be increased. [10] Fluid movement inside the dentinal tubules may be away from or towards the pulp. Dentine contains many thousands of microscopic tubular structures that ...
One drop (32.5 μL) is ample material to treat 5 teeth, and contains 12.35 mg silver diamine fluoride. Assuming the smallest child with caries would be in the range of 10 kg, the dose would be 1.235 mg / kg child. Based on this, UCSF recommended 1 drop per 10 kg of body weight per visit. [16]

About 85% of stones occur in the submandibular gland, [3] and 5–10% occur in the parotid gland. [2] In about 0–5% of cases, the sublingual gland or a minor salivary gland is affected. [ 2 ] When minor glands are rarely involved, caliculi are more likely in the minor glands of the buccal mucosa and the maxillary labial mucosa. [ 4 ]
