MDS PREP
A teenaged patient reported complaining of sudden drifting of teeth. Bone loss and pockets were found to be more severe on some teeth when compared to neighboring teeth. The most likely diagnosis is
1. simple periodontitis
2. chronic nonspecific periodontitisv
3. juvenile periodontitis
4. gingivosis
Periodontics
Answer: 3
Juvenile periodontitis (now referred to as localized aggressive periodontitis)
is characterized by localized bone loss and periodontal pockets, often affecting
adolescents and young adults. The sudden drifting of teeth and the severity of
bone loss in specific areas align with this diagnosis.
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.
Secondary occlusal traumatism is least likely to be associated with
1. inflamed gingiva
2. bruxism
3. tooth mobility
4. migration of teeth
Periodontics
Answer: 1
Secondary occlusal trauma primarily relates to occlusal discrepancies or effects
on tooth mobility due to periodontal attachment loss rather than localized
gingival inflammation alone.
Ostectomy procedure is indicated in
1. Physiological architecture of alveolar bone
2. Correction of tori
3. Reverse architecture bone defects
4. Correction of bone ledges
Periodontics
Answer: 3
Ostectomy procedures are indicated for reverse architecture bone defects.
Efficient way of calculus removal is
1) A relaxed instrument grasp and light lateral working strokes
2) A tight instrument grasp and light lateral working strokes
3) A tight instrument grasp and firm lateral working strokes
4) None of the above
Periodontics
Answer: 3
Explanation:
For effective calculus removal, a tight instrument grasp combined with firm lateral working strokes is essential. This technique allows for better control and application of force, which is necessary to effectively dislodge calculus from the tooth surface.
The best way to prevent exposure of dehiscene during surgical procedure is to
1. Elevate a double flap
2. Elevate full thickness flap
3. Elevate partial thickness flap
4. Elevate coronally repositioned flap
Periodontics
Answer: 3
The best way to prevent exposure of dehiscence during a surgical procedure is to elevate a partial thickness flap.
Which of the following drug regimens is not likely to influence periodontal therapy?
1. Propranolol
2. Antihistamine
3. Sodium warfarin
4. Corticosterone
Periodontics
Answer: 2
Antihistamines are not typically associated with significant effects on
periodontal therapy. In contrast, propranolol (a beta-blocker), sodium warfarin
(an anticoagulant), and corticosteroids can all influence periodontal health and
treatment outcomes.
