Acute Necrotizing Ulcerative Gingivitis

 # Which of the following is not found in acute necrotizing ulcerative gingivitis?

A. Pocket formation

B. Tooth loss

C. Bone loss

D. Gingival recession

The correct answer is A. Pocket formation.

NUG or NUP does not usually lead to periodontal pocket formation, because the necrotic changes involve the junctional epithelium, a viable junctional epithelium is needed for pocket deepening.

Cone Cut in Radiograph

 # Which of the following describes the etiology of cone-cutting?

A. Inadequate exposure time

B. Excessive mA

C. Excessive kVp

D. Incorrect source-object distance

E. Incorrect placement of X-ray machine

The correct answer is E. Incorrect placement of X Ray machine.

Cone-cutting occurs when the X-ray machine is not lined up properly with the X-ray sensor or film.

The film or sensor should be placed perpendicular to the X-ray

collimator to ensure that all of the necessary information is picked

up.

External devices are often used to ensure that the film/sensor are

perpendicular to the X-ray collimator.

SLOB technique

  # A periapical radiograph suggests an opaque mass Over the apex of the maxillary right 2nd molar. A second periapical radiograph is made with the X-ray head adjusted in a more mesial direction. The second periapical suggests that the object in question has moved distally compared to the 1st radiograph. Which of the following directions describes the location of the object?

A.In-between the roots

B. Buccal to the tooth

C. Lingual to the tooth

D. Not enough information is provided

The correct answer is B. Buccal to the tooth.

The SLOB (Same Lingual, Opposite Buccal) rule suggests that the

object is buccal to the tooth.

Because the object moved opposite to the positioning of the X-ray

device for the 2nd radiograph it demonstrates buccal positioning

If the object moved mesially with the head of the X-ray head being

moved mesially, it would have demonstrated lingual/palatal

positioning.

Difficulty in pronouncing T

 # A person wearing complete denture has difficulty in pronouncing T. The reason may be:

A. Too thick palatal area

B. Incorrect position of upper incisor teeth

C. Too thick mandibular bone

D. Reduced salivary flow

The correct answer is B. Incorrect position of upper incisor teeth. 

- Sounds like t, d, n, etc. are alveolar sounds. These sounds are produced with tip of tongue touching anterior palate.

- If maxillary anterior teeth are placed too far anteriorly, 'd' will sound like 't'.

- If they are placed too palatally, 't' will sound like 'd'. 

Lentulo spiral uses

 # Lentulo spirals are used for:

A. Locating canal orifice

B. Pulp extirpation

C. Enlarging coronal third of the root canal

D. Application of root canal sealer

The correct answer is D. Application of root canal sealer. 

- Finger pluggers are used for vertical compaction of gutta percha. 

- Finger spreaders are used for  lateral compaction of gutta percha.

- Lentulo spiral is used to deliver sealer or triple antibiotic paste to the root canal.

BPKIHS Online OPD Registration

 

B.P. Koirala Institute of Health Sciences (BPKIHS) has initiated an innovative service of Online registration and ticketing for providing OPD services from 2077-06-26. For this, the patients have to get themselves registered from the Android App BPKIHS  

Patients have to:

- register their personal details

- select the desired department and register the ticket / pay the stipulated amount via Khalti or eSewa or IMEPay

- If registered before 8:00 AM, the patients will be registered for the same day, and those registering after 8:00 AM will be registered for the next day. Patients have to collect their OPD cards from the counter in the respective departments and enter the doctor's chamber. 

At present, this service is available only for routine OPD (daily regular OPD). In the upcoming days, Institutional based private practice (Private OPD) registration will also be incorporated in the app.

Staffs from respective departments working in the OPD should collect the OPD cards of the patients registered through online within 9:00 AM on the same day.

Age related gingival recession

# Age-related gingival recession can be best treated by:

A. Gingivoplasty

B. Pedicle graft

C. Free gingival graft

D. No treatment

The correct answer is D. No treatment.

Gingival recession increases with age, the incidence varies from 8% in children to 100% after the age of 50 years. This has led to some investigators to assume that recession may be a physiologic process related to ageing.
