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

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.
Absorbed fluoride is eliminated by
1) Kidneys
