Quiz 1 (BASIC) | Periodontics

#1. Which index is commonly used to screen patients’ periodontal status?

Approximal Plaque Index (API)

Sulcus Bleeding Index (SBI)

Periodontal Screening and Recording Index (PSR)

None of above

#2. While screening periodontal status in children, which representative teeth are used for assessment?

All the primary teeth present at the time of recording

All the permanent teeth present at the time of recording

16, 11, 26 in upper and 36, 31, 46 in lower jaw

16, 21, 26 in upper and 36, 41, 46 in lower jaw

#3. If the total number of reading sites in patients’ dentition is 25 and number of positive sites with biofilm is 12. What is the patient’s API (%)?

20%

45%

48%

60%

#4. Name three diagnostic instruments, most used for clinical screening and diagnosis of periodontal diseases?

Periodontal explorer, Naber’s probe and periodontal color-coded probe

WHO probe, pig-tail explorer and colour coded implant probe

Biotype indicator probe, WHO probe and periodontal explorer

Naber’s probe, periodontal color-coded probe and WHO probe

#5. Which 6 parameters are recorded while completing a full mouth point periodontal chart?

Sulcus bleeding, approximal plaque index, probing depth, gingival recession, width of keratinized gingiva and gingival suppuration

Bleeding on probing, probing depth, gingival recession, furcation involvement, tooth mobility and clinical attachment loss

Probing depth, gingival recession, width of keratinized gingiva, gingival suppuration and bleeding, fluctuation of any swelling present

Bleeding on probing, probing depth, gingival recession, gingival biotype, tooth drifting rate and mobility

#6. What is clinical attachment loss (CAL)?

Distance from the cemento-enamel junction (CEJ) to the coronal portion of junctional epithelium (JE)

Distance from the cemento-enamel junction (CEJ) to the gingival margin (GM)

Distance from the gingival margin (GM) to the bottom of the periodontal pocket

None of above

#7. If gingival margin is 5mm coronal to the cemento-enamel junction (CEJ) and probing depth (PD) is 7mm. Where is the junctional epithelium attachment (JE)?

JE attachment is 3mm apical to the cemento-enamel junction (CEJ)

JE attachment is just at the cemento-enamel junction (CEJ)

JE attachment is 2 mm coronal to the cemento-enamel junction (CEJ)

JE attachment is 2 mm apical to the cemento-enamel junction (CEJ)

#8. Bottom of the pocket is 4mm apical to the cemento-enamel junction (CEJ) and gingival margin is 3mm coronal to the cemento-enamel junction (CEJ). What is the depth of the periodontal pocket?

4mm

6mm

7mm

1mm

#9. The gingival margin is at the level of the cemento-enamel junction (CEJ) and clinical attachment loss (CAL) is 4mm. What is the depth of the periodontal pocket (PD)?

1mm

3mm

4mm

5mm

#10. What is the main difference between periodontal pocket and gingival (false or pseudo-) pocket?

Periodontal pocket is always deeper than gingival pocket

Periodontal pocket may be seen in both, patients with gingivitis and periodontitis

Periodontal pocket has its bottom apical to the cemento-enamel junction (CEJ)

Periodontal pocket can be only detected by periapical radiograph
