The bacteria found in gingivitis are located in the
1. alveolar bone
2. periodontal pocket
3. periodontal ligament
4 connective tissue of the marginal gingiva
Periodontics
Answer: 4
In gingivitis, bacteria primarily reside in the connective tissue of the
marginal gingiva and within the plaque biofilm on the tooth surface. This
location contributes to the inflammatory response seen in gingivitis.
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.
Subgingival calculus is highest in
1) Lower anterior region
2) Lower bicuspid region
3) Lower molar region
4) Upper molar region
Periodontics
Answer: 1
Subgingival calculus
is often found in the lower anterior region due to the
anatomy and position of the teeth.
Which of the following procedures is least successful in resolving a periodontally related osseous defect
1. Osseous coagulum graft
2. Resection surgery
3. Reattachment procedure
4. Alloplast graft
The procedure least successful in resolving a periodontally related osseous defect is the reattachment procedure.
Periodontal pack is least effective in
1) Providing splinting action
2) Haemostatic mechanism
3) Pain elimination
4) Antimicrobial action
Periodontics
Answer: 3
Periodontal packs are primarily used for their antimicrobial, haemostatic, and splinting properties. While they provide a good antimicrobial environment and can aid in haemostasis, they are not typically used for pain elimination. The main purpose of a periodontal pack is to deliver medication directly to the periodontal pocket and help stabilize the gum tissue around the teeth. Pain relief is generally managed through other means such as analgesics or local anesthetics.
Which of the following periodontal diseases does not have calculus:
1. ANUG.
2. Chronic adult periodontitis.
3. Juvenile periodontitis.
4. Periodontal abscess.
Periodontics
Answer: 3
Juvenile periodontitis, now referred to as localized aggressive periodontitis, is characterized by the loss of periodontal attachment and bone in adolescents and young adults, often without the presence of significant calculus. This distinguishes it from other forms of periodontitis, where calculus is typically present.
Craters in facial and lingual interdental bone are best eliminated by
1) Gingivectomy
2) Osseous reconturing
3) Osseous regeneration procedure
4) Curettage
Periodontics
Answer: 3
Craters in the facial and lingual interdental bone are typically associated with periodontal disease and result from the loss of bone due to inflammation and infection. Osseous regeneration procedures, such as guided bone regeneration (GBR) or the use of bone grafts, are specifically designed to restore lost bone structure. These procedures promote the growth of new bone in the affected areas, effectively filling in the craters and restoring the contour of the alveolar ridge. Gingivectomy and curettage are more focused on soft tissue management and do not address the underlying bone loss, while osseous recontouring may not be as effective in restoring lost bone volume.
The finger rest established on tooth surfaces on the opposite side of the same arch is known as
1. Conventional finger rest
2. Opposite arch finger rest
3. Cross-arch finger rest
4. Finger-on-finger rest
The finger rest established on tooth surfaces on the opposite side of the same arch is known as cross-arch finger rest.
