[Guest guest]

please need help in these questions1.The obturation technique which

gives the best hermetic seal for gutta-percha in endodontics

a. warm

lateral compaction

b. warm

vertical compaction

c. thermoplasticised

gutta-percha techniques

d. cold

lateral compaction

e. chlorpercha

2.Which antibiotic interferes in

the action of warfarin resulting in an increased prothrombine time?

a. Erythromycin

b. Metronidazole

c. Penicillin

d. tetracycline

3,Which is the most suitable

examination for the diagnosis of caries in a stained fissure

a. transillumination

b. bitewing

c. probing

d. DPT

4.According to the Electricity at

Work Regulations 1989 electrical equipment must be tested every?

a. three years

b. one year

c. two years

d. 6 months

5.Fire certificates are only

required for buildings with 20 people working in them or if more than ten

people work on floors other than ground floors (same applies to dental

practices). Fire risk assessment should be carried every

a. 3 months

b. 6 months

c. 9 months

d. one year

6. false, true

a. calcium hydroxide is the material most commonly used for induction of

an apical barrier formation in non-vital immature permanent teeth

b. full working length for filling the root canal should be within 1mm of

the radiographic apex

c. it does not matter if the calcium hydroxide paste does not fill the

root canal completely to the apex

d. calcium hydroxide may act as an irritant and hence stimulate the body’s

repair mechanism to produce the hard tissue barrier

7. false, true

a. tooth is tender to pressure and slightly mobile. This could

indicate apical periodontits and the need to commence endo treatment

b. tooth does not respond to thermal and electrical vitality testing while

positive responses are obtained from adjacent non-traumatised teeth. Pulpal

necrosis has therefore occurred

c. on transillumination the tooth has a slight pink colour. Endodontic

treatment is therefore indicated

d. a radiograph indicates that a periapical radiolucency has developed

since the initial examination and that external root resorption has begun.

Endodontic treatment should therefore be undertaken.

skeletal class I, posterior cross bite, anterior open bite, reduced length of

body of mandible, dentoskeletal compensation

a. commonly seen in class III malocclusion

b. reduced transverse dimensions of maxilla

c. reduced mandibular body length

d. bird facies technology

2.calcium hydroxide, formocresol,

beechwood creosote, EDTA, pulpotomy, pulpectomy, MTA, ledermix

a. removal of entire coronal and radicular pulp,

b. used for devitalising pulpotomies in primary teeth

c. used for vital pulpotomies in primary teeth

d. used for apexification in permanent teeth
