Which of the following statements is correct regarding the size of the face at birth?
1) The face forms 2/3rd the bulk of head whereas in the adult it forms 1/3rd of the bulk.
2) The face forms the bulk of the head through life
3) The face forms 1/3rd the bulk of the head, whereas in the adult it forms 1/8th of the bulk
4) The face forms only 1/8th of the bulk of head whereas in the adult it forms 1/3rd to of the bulk.
Pedodontics Answer: 4
Due to the advanced state of the growth of brain this size at birth of the head of the infant is relatively large . only 1/8th of the bulk of the head forms the face at this age, whereas in the adult it forms 1/3rd to of the bulk. The face appears to be under the bulge of the forehead because the vault of the cranium is so large
Identify the wrong statement regarding true except
1. Association with gingivitis
2. Associated with periodontitis
3. May not cause bleeding on probing
4. None of the above
Pedodontics
Answer: 1
Gingivitis is typically associated with plaque-induced inflammation of the gingiva, but not all gingival lesions directly correlate with other periodontal conditions like periodontitis or specific non-bleeding phenomena.
Probing depth of a pocket is accessed by
1. Williams probe
2. Naber"s probe
3. DNA probe
4. RNA probe
Probing depth of a pocket is assessed by the Williams probe.
Head shape in Down"s syndrome is typically
1) Mesocephalic
2) Dolicocephalic
3) Brachycephalic
4) Acephalic
Pedodontics
Answer: 3
Head shape in Down's syndrome is typically brachycephalic.
Explanation: Down's syndrome, also known as trisomy 21, is a genetic disorder that can lead to a range of physical and developmental characteristics. One of the common features of individuals with Down's syndrome is a brachycephalic head shape. Brachycephaly is a condition where the head appears relatively broad and short, with the breadth being disproportionately greater than the length. This characteristic is due to the premature fusion of certain skull sutures, which can also result in a flattened facial profile and a shortened neck. While the head shape is not a definitive diagnostic feature, it is often present in those with the condition.

In a 9-year-old which permanent tooth surface will show greatly increased caries incidence
1) Labial surface of central incisor
2) Occlusal surface of central incisor
3) Mesial surface of central incisor
4) Occlusal surface of lateral incisor
Pedodontics
Answer: 1
In children, the labial (facial) surfaces of anterior teeth, particularly the central incisors, are more prone to caries due to factors such as plaque accumulation, dietary habits, and the developmental stage of the teeth. The labial surface is more exposed to the oral environment and is often less effectively cleaned compared to other surfaces, making it susceptible to decay.
Radiograph of a periodontal ligament of a tooth which has lost its antagonist shows
1. Widening of the PDL space
2. Narrowing of PDL space
3. Increased density
4. Sclerotic change
Pedodontics
Answer: 2
