Answer: 2
Patient records, including dental X-ray films, are typically the property of the dentist who created them. The dentist is responsible for maintaining, storing, and safeguarding these records according to legal and professional standards. However, patients do have the right to access and obtain copies of their records.
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.

used for trace chemotherapy waste.
2) Black: Typically used for non-infectious waste that is not recyclable, such
as general waste from hospital areas not directly involved in patient care.
3) Green: This is commonly used for anatomical waste, which includes human
tissues, organs, body parts, and animal carcasses used in research or treatment.
4) Red: As mentioned, is used for infectious or biohazardous waste that poses a
risk of infection or disease transmission.

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
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.

2) Age of child and fluoride content of water
3) Age of the child only

Community Dentistry
Answer: 2
Recommended Doses of Fluoride Tablets
For Children Aged 6 Months to 4 Years:
Liquid drops are typically prescribed in doses of 0.125, 0.25, and 0.5
mg of fluoride ion.
For Children Aged 4 Years and Older:
Chewable tablets or lozenges are recommended, usually at doses of 0.5 mg
to 1 mg of fluoride ion.
Adjustments Based on Water Fluoride Levels:
Doses may be adjusted based on the fluoride content in the child's
drinking water to ensure adequate protection against dental caries.
Duration of Supplementation:
Fluoride supplementation is generally continued until the child reaches
16 years of age, depending on their fluoride exposure and dental health
status.
