Asymptomatic irritational fibroma should be treated by:

 # Asymptomatic irritational fibroma should be treated by:

A. Simple excision

B. Block resection

C. Radiation therapy

D. No treatment indicated

The correct answer is A. Simple excision.

The treatment for the fibroma, or focal inflammatory hyperplasia as the case may be, is conservative surgical excision. Seldom does the lesion recurs.

Surface of an oral squamous cell carcinoma

 # The surface of an oral squamous cell carcinoma will usually feel to the touch:

A. Smooth

B. Fluctuant

C. Slimy

D. Rough

The correct answer is D. Rough.

Clinically, almost all oral cancers, except those in the earliest stages have two very characteristic features in the form of ulceration and an indurated margin. In different sites; however, there are certain variations.

A smooth red tongue may be seen in all of the following except:

 # A smooth red tongue may be seen in all of the following except:

A. Vitamin K deficiency

B. Folic acid deficiency

C. Iron deficiency anemia

D. Vitamin  B12 deficiency

The correct answer is A. Vitamin K deficiency.

While an iron-deficiency anemia may occur at any age, the Plummer-Vinson syndrome occurs chiefly in women in the fourth and fifth decades of life. Presenting symptoms of the anemia and the syndrome are cracks or fissures at the corners of the mouth (angular cheilitis), a lemon-tinted pallor of the skin, a smooth, red, painful tongue (glossitis) with atrophy of the filiform and later the fungiform papillae, and dysphagia limited to solid food resulting from an esophageal stricture or web. These oral findings are reminiscent of those seen in pernicious anemia.

The word dilaceration means:

 # We understand one of the following by the word dilaceration?

Calcified root canals

Curvature of the root tip

Dysplasia of dentin

Cemental union of root

The correct answer is B. Curvature of the root tip.

The term ‘dilaceration’ refers to an angulation, or a sharp bend or curve, in the root or crown of a formed tooth. The condition is thought to be due to trauma during the period in which the tooth is forming, with the result that the position of the calcified portion of the tooth is changed and the remainder of the tooth is formed at an angle. The curve or bend may occur anywhere along the length of the tooth, sometimes at the cervical portion, at other times midway along the root or even just at the apex of the root, depending upon the amount of root formed when the injury occurred.

Macroglossia may be seen in:

 # Macroglossia may be seen in:

A. Prader willi syndrome

B. Down syndrome

C. Beckwith Weidemann syndrome

D. Grebe syndrome

The correct answer is C. Beckwith Weidemann syndrome.

Although the exact incidence of macroglossia is unknown (because the etiologies are too numerous to quantify), some congenital syndromes often express macroglossia in their phenotypes, most commonly Down syndrome (1 per 700 live births) and Beckwith-Wiedemann syndrome (0.07 per 1,000 live births). In Beckwith-Wiedemann syndrome, 97.5% of patients have macroglossia.

 # Cytologic smears and the findings of characteristic multinucleated giant cells (Tzanck test) are helpful in the diagnosis of:

A. Chicken pox

B. Mumps

C. Psoriasis

D. Herpes Zoster

The correct answer is D. Herpes Zoster.

Herpes zoster can frequently be recognized by the characteristic distribution of the lesions, although there may be a similarity to the lesions of herpes simplex infection. Skin lesions and oral lesions in particular may be easily identified as viral diseases by cytologic smears and the finding of characteristic multinucleated giant cells (Tzanck test) and intranuclear inclusions. However, this does not differentiate between herpes zoster and herpes simplex. This can only be done by fluorescent antibody staining techniques, viral culture or serologic diagnosis.

Which of the following compulsorily involves two teeth?

 # Which of the following compulsorily involves two teeth?

A. Dilaceration

B. Gemination

C. Taurodontism

D. Concrescence

The correct answer is D. Concrescence.

Concrescence of teeth is actually a form of fusion which occurs after root formation has been completed. In this condition, teeth are united by cementum only. It is thought to arise as a result of traumatic injury or crowding of teeth with resorption of the interdental bone so that the two roots are in approximate contact and become fused by the deposition of cementum between them. Concrescence may occur before or after the teeth have erupted, and although it usually involves only two teeth, there is at least one case on record of union of three teeth by cementum.
