# House Brackman Scale is used for evaluation of which nerve function?

A. Facial

B. Trigeminal

C. Optic

D. Hypoglossal

The correct answer is A. Facial.

House-Brackmann facial paralysis scale

Grade Impairment

I Normal

II Mild dysfunction (slight weakness, normal symmetry at rest)

III Moderate dysfunction (obvious but not disfiguring weakness with synkinesis, normal symmetry at rest) Complete eye closure w/ maximal effort, good forehead movement

IV Moderately severe dysfunction (obvious and disfiguring asymmetry, significant synkinesis) Incomplete eye closure, moderate forehead movement

V Severe dysfunction (barely perceptible motion)

VI Total paralysis (no movement)

*Please note: This scale is used to evaluate facial paralysis at the nerve trunk, and is not a descriptive scale to describe an injury to specific distal facial nerve branches.

Spontaneous nystagmus

First degree: nystagmus on gaze toward the quick component

Second degree: nystagmus on gaze toward the quick component and on straight gaze

Third degree: nystagmus in all directions of gaze

Most Important Operative Dentistry MCQs With Explanations

1. The following chemically bond to the tooth: A. Composite resin. B. Dental sealants. C. Glass ionomer cement. *** D. All of the above. 2. Compomer restorative materials are: A. Glass ionomer with polymer components B. Resin systems with fluoride containing glasses. *** C. Composite resin for cervical restorations only. Explanation: The composition of compomers is similar to that of a dental composite however it has been modified, making it a polyacid-modified composite. This results in compomers still requiring a bonding system to bond to tooth tissue. Although the name compomer implies that the material possesses a combination of characteristics of both composite and glass ionomers, these materials are essentially polymer-based composites that have been slightly modified to take advantages of the potential fluoride-releasing behavior of glass ionomers. 3. Loose enamel rods at the gingival floor of a class II amalgam cavity should be removed using : A. Straight chisel...
