The usual metabolic pathway of ingested fluoride involves urinary excretion primarily with the remaining portion found largely in
1) Teeth
2) Muscle
3) Skeletal tissues
4) Liver
Community Dentistry
Answer: 3
Fluoride is absorbed in the gastrointestinal tract and is distributed throughout the body. A significant portion of ingested fluoride is excreted through urine. However, fluoride also accumulates in skeletal tissues, including bones and teeth, where it can contribute to the mineralization process and enhance resistance to dental caries. The skeletal system retains fluoride, which can be beneficial in small amounts but may lead to toxicity if excessive.

Which of the following teeth are application for simplified oral hygiene index
1) Lingual surface of 36, 46 and facial surface of 11, 16, 26, 31
2) Lingual surface of 31, 36, 46 and facial surface of 11, 16, 26, 31
3) Lingual surface of 11, 31 and facial surface of 16, 26, 36,46
4) None of the above
Community Dentistry
Answer: 1
The Simplified Oral Hygiene Index (OHI-S) is a tool used to assess oral hygiene status by evaluating specific tooth surfaces. The teeth mentioned in option 1 include the lingual surfaces of the lower first molars (36, 46) and the facial surfaces of the upper incisors and canines (11, 16, 26, 31). These surfaces are typically assessed because they are representative of overall oral hygiene and are commonly affected by plaque accumulation.
The dental records should be preserved for a minimum period of
1) 7 years from the data of last entry
2) 7 years from the data of first entry
3) 7 months from the data of last entry
4) 7 years from the data of first entry
Community Dentistry
Answer: 1
7 years from the date of last entry: Dental records are crucial for patient care, legal documentation, and professional accountability. The Dental Council of India (DCI) mandates the preservation of dental records for at least 7 years from the date of the last entry. This ensures that in case of any future reference or legal disputes, the records are readily available. It is essential for continuity of care and patient follow-up.
The main site of absorption of ingested fluorides is
1) Esophagus
2) Stomach and small intestine
3) Small and large intestine
4) Large intestine
Community Dentistry
Answer: 2
Fluoride is absorbed primarily in the gastrointestinal tract, with the stomach and small intestine being the main sites of absorption. The acidic environment of the stomach facilitates the dissolution of fluoride, allowing it to be absorbed effectively. While some absorption occurs in the large intestine, the majority takes place in the stomach and small intestine

variation or dispersion in a set of values. It indicates how much individual
data points differ from the mean.
