 # All are true about dental anomalies in cleft patients EXCEPT:

A. Hypodontia is the most commonly observed dental anomaly

B. Incidence of dental anomalies is strongly correlated with cleft severity

C. Maxillary lateral incisor is the most frequently affected tooth in the cleft area

D. Dental anomaly occurs more frequently on the non cleft side

The correct answer is D. Dental anomaly occurs more frequently on the non cleft side.

Explanation:

A. Hypodontia is the most commonly observed dental anomaly: True. Hypodontia, particularly in the maxillary lateral incisors, is frequently observed in cleft patients.

B. Incidence of dental anomalies is strongly correlated with cleft severity: True. More severe clefts are often associated with a higher prevalence of dental anomalies.

C. Maxillary lateral incisor is the most frequently affected tooth in the cleft area: True. This tooth is commonly missing, malformed, or displaced in cleft patients.

D. Dental anomaly occurs more frequently on the non-cleft side: False. Dental anomalies occur more frequently on the cleft side due to the disruption of normal development in the region of the cleft.

If retromolar pad and tuberosity contact, what should be done?

 # If retromolar pad and tuberosity contact, what should be done?

A. Surgical reduction of tuberosity

B. Do not extend dentures to retromolar area

C. Denture fabrication not possible

D. Has no effect on denture

The correct answer is A. Surgical reduction of tuberosity.

A. Surgical reduction of tuberosity

If the retromolar pad and tuberosity contact, it can hinder proper denture seating and stability. Surgical reduction of the tuberosity creates space for the denture to fit properly and function effectively.
