Bone graft procedures are most successful in treating
1) Furcation involvements
2) Deep, two-wall craters
3) Narrow three-wall defects
4) None of the above
Periodontics
Answer: 3
Bone graft procedures are most successful in treating narrow three-wall defects. These are defects that extend from the crest of the alveolar bone to the alveolar crest and involve only one surface of the tooth root. The success of a bone graft in such cases is due to the presence of three walls of intact bone that can provide stability and support for the graft material, allowing for predictable and effective regeneration of the missing bone tissue.
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.
A tight grasp by the operator on the explores will
1. Prevent tactile sensitivity
2. Provide greater maneuverability
3. Prevent muscle fatigue of the fingers
4. All the above
Periodontics
Answer: 1
A tight grasp by the operator on the explorer will prevent tactile sensitivity.
ANUG is caused by
1. Borrelia vincenti and Fusobacterium
2. Actinomycetam comitans
3. Actinomyces naeslundii
4. Streptococcus mutans
ANUG is caused by Borrelia vincenti and Fusobacterium.
Most of the microorganisms present a two day old dental plaque will be
1. lactobacilli
2. fusiform bacilli
3. vibrios
4. cocci
Periodontics
Answer: 4
In the early stages of dental plaque formation, particularly within the first
few days, the predominant microorganisms are typically cocci, especially Streptococcus species.
These bacteria are among the first to colonize the tooth surface after a
cleaning, forming a biofilm.
Lactobacilli are more commonly associated with mature
plaque and caries development, as they thrive in acidic environments.
Fusiform bacilli and vibrios are more
commonly found in later stages of plaque development or in specific
conditions, such as periodontal disease.
Thus, in a two-day-old dental plaque, the majority of microorganisms will
indeed be cocci
For interproximal areas of disastemata or for wide interdental spaces to properly adopt the interproximal papilla against the bone, the recommended technique to suturing method is
1. Interdental ligation
2. Horizontal mattress suture
3. Continuous, independent sling suture
4. Closed anchor suture
Periodontics
Answer: 2
The recommended suturing method for interproximal areas of diastemata is horizontal mattress suture.
The first sequential step in osseous resection technique
1. Vertical grooving
2. Radicular blending
3. Flattening interproximal bone
4. Gradualising marginal bone
Periodontics
Answer: 1
The first sequential step in the osseous resection technique is vertical grooving.
