Pediatrics MCQ Answers

1. True

2. Disorders of tooth eruption and positioning (premature, delayed, or failure of eruption, malocclusion or abnormal alignment), abnormalities of tooth number (supernumerary tooth), size and shape (macrodontia, microdontia, or twinning), structure (AI or DI), and color (intrinsic or extrinsic staining).

3. False. Dentinogenesis imperfecta is the condition that may occur with osteogenesis imperfecta.

4. Streptococcus mutans

5. Fluoride supplementation, good oral hygiene that includes brushing and flossing, limiting the amount but more importantly the frequency of intake of sweets (especially the habit of bedtime bottle feeding, eating in between meals and at bedtime), regular dental visits.

6. It is very likely that this history is not correct. These appear to be baby bottle caries, which is the most likely cause. It may be that mother feels guilty that she is not following your advice so she is denying that the child continues to go to bed with a bottle. Another possibility is that she is giving the child juice in a bottle at night and does not consider this to be “bottle feeding”. Grandparents living in the same household will often interfere with childhood rearing practices, since they may insist on letting the child have a bottle to prevent the child from crying.

7. The best thing to do with the tooth is to push it back into its original location after a gentle rinse, if the child is cooperative. Otherwise, the tooth can be placed in saline gauze or milk. The tooth should not be scrubbed.
