c. Mixed dtumor
d. Ranula
ANS: d B
A dtorus dpalatinus dis ddevelopmental dand dbony dhard dand dis dfound don dthe dmidline dof dthe
dpalate. dDiagnosis dis dmade don dthe dbasis dof dclinical dappearance. dA dpalatal dcyst dappears
dradiolucent don da dradiographic dexamination dand dis dnot ddiagnosed dthrough dclinical
dappearance. dA dmixed dtumor dordpleomorphic dadenoma dis da dbenign dtumor dof dsalivary
dgland dorigin, dfound dunilaterally doff dthe dmidline dof dthe dhard dpalate. dIt dis dcomposed dof
dtumor dtissue dthat dis dnot dbony dhard dto dpalpation.

dcause dof dwhich dis dunknown. dWhitedsponge dnevus dis da dgenetic d(autosomal ddominant)
dtrait. dClinically, dit dis dcharacterized dby da dsoft dwhite, dfolded d(or dcorrugated) doral

Angular dcheilitis dmost dcommonly dresponds dto dantifungal dtherapy donce dnutritional
ddeficiencies dhave dbeen druled dout. dAmelogenesis dimperfecta dis da dgenetic dcondition
dassociated dwith dabnormalddevelopment dof dthe denamel. dPaget ddisease dis da dchronic
dmetabolic dbone ddisease. dA dhighly delevated dserum dalkaline dphosphatase dlevel
dcontributes dsignificantly dto dthe ddiagnosis. dA dStafne dbone dcyst dis ddetermined dthrough

Nifedipine dis da dcalcium dchannel dblocker. dDilantin dis dan danticonvulsant dused dto dprevent
dordcontrol dseizures. dQuinidine dis dan dantiarrhythmic dagent dused dto dtreat dcardiac
darrhythmias. dClozapine dis dan dantipsychotic dused din dthe dmanagement dof dpsychotic
