Ideal thickness of graft should be
1. 1.0 to 1.5 mm
2. 0.25 to 0.5 mm
3. 0.5 to 1 mm
4. 2-3 mm
Periodontics
Answer: 1
The ideal thickness for a graft is typically between 1.0 to 1.5 mm to ensure adequate healing and integration.
In which of the following procedures, periodontal pack is not given
1. Gingivectomy
2. GTR procedures without osseous transplants
3. Osteoimplants with reattachment procedures
4. Osteoplasty procedure
Periodontics
Answer: 2
In periodontal surgery, a periodontal pack is not given in GTR procedures without osseous transplants.
Osseous form is considered to be ideal when
1. Redicular bone is apical to interdental bone
2. Interdental bone is apical to radicular bone
3. Bone is more coronal in interproximal surface than facial and lingual sides
4. None of the above
Periodontics
Answer: 3
Osseous form is considered ideal when the bone is more coronal in the interproximal surface than the facial and lingual sides.
According to Melcher concept, the regeneration of new attachment is from
1. Periodontal ligament
2. Gingival connective tissue
3. Alveolar bone
4. Junctional epithelium
Periodontics
Answer: 1
According to Melcher's concept, the regeneration of new attachment is from the periodontal ligament.
Which of the following roots are most likely to have flutings in their mesial surfaces which will make thorough root planning difficult?
1. Maxillary central incisor
2. Mandibular second premolar
3. Maxillary first premolar
4. Mandibular canine
Periodontics Answer: 3
The maxillary first premolar often has developmental grooves and flutings on the
mesial surface that can complicate thorough root planing and make it more
challenging to fully debride the root surface.
Angulation of a periodontal instrument refers to the
1) Angle between the face of the blade and the shank
2) Angle between the shank and the shaft
3) Angle between the face of the blade and the tooth surface
4) Angle between the shank and the tooth surface
Periodontics
Answer: 3
In periodontal instrumentation, angulation is crucial for effective scaling and root planing. The angulation refers to the relationship between the face of the instrument's blade and the surface of the tooth being treated. Proper angulation allows for optimal removal of calculus and plaque. The other options refer to different relationships that are not specifically defined as "angulation" in the context of periodontal instruments.
Vestibular extension procedure results in
1. Increase in width of keratinised attached gingiva
2. Decrease in width of keratinised attached gingiva
3. Increase in width of non-keratinised attached gingiva
4. Decrease in width of non-keratinised attached gingiva
Periodontics
Answer: 3
Vestibular extension procedure results in an increase in width of non-keratinised
attached gingiva
The vestibular extension procedure is a surgical treatment that involves the
apical movement of the vestibular mucosal tissue to increase the width of
attached gingival tissue around a tooth. This procedure typically does not alter
the width of the keratinized attached gingiva, which is the tissue that is
directly connected to the tooth surface. Instead, it primarily increases the
non-keratinized attached gingival width, which is the part of the gingival
tissue that is not directly attached to the tooth but is still important for
periodontal health and aesthetics.
Cervical abrasion is usually the result of
1. acidic fluids
2. sulcular brushing
3. gingival sulcular fluids
4. horizontal brushing
Periodontics
Answer: 4
Cervical abrasion is often caused by improper brushing techniques, particularly
horizontal brushing, which can wear away the enamel and dentin at the cervical
area of the teeth.
