The use of a reservoir on the sprue of a wax pattern decreases:
A. volumetric changes in the casting
B. casting porosity from inclusion of gases
C. casting porosity from inclusion of foreign bodies
D. casting porosity during solidification.
in contemporary fixed prosthodontics, page 682 one of the requirements is the metal within the sprue must remail molten longer than the alloy that has filled the mold. this provides a reservoir to compensate for shrinkage during solidification...
thus, i think the naswer is A

When a removable partial denture is
fabricated to occlude with natural teeth, the

influenced by the
A. endodontic condition of the abutment
teeth.
B. occlusal form of the remaining teeth.
C. need to produce a fully balanced
occlusion.
D. None of the above. .
What do you think. Could you recommend any reference?

i think it should be occlusal form of the opposing teeth.
so i pick D

I know it is difficult to imagine but casting porosity can be due 3 factors, entrapment of gases,inclusion of metal particles and solidification shrinkage, it is written in Mccrckn.
i think like Dr cc said this question has a very strong distractor so hopefully it won't be in the exam.

i mean since the answer should be "the occlusal form of the opposing tooth ",and there is not such an option, the D, "none of the above" is the right pick.
You are well prepared Leda. I looked it up - in erythematous candidiasis there may be lesions resembling median rhomboid glossitis, however it is confusing whether you can call them a smooth red tongue in general, because it is a patch. But I guess you are right, all of the above.

Reviewing :
Prophylaxis for endocarditis recommended in patients receiving dental care
High-risk category
Prosthetic cardiac valves, including both bioprosthetic and homograft
valves
Previous bacterial endocarditis
Complex cyanotic congenital heart disease (e.g., single ventricle states,
transposition of the great arteries, tetralogy of Fallot)
Surgically constructed systemic pulmonary shunts or conduits
Moderate-risk category
Most congenital cardiac malformations other than above and below (see
next question)
Acquired valvular dysfunction (e.g., rheumatic heart disease) Hypertrophic cardiomyopathy
Mitral valve prolapse with valvular regurgitation and/or thickened leaflets
Dajani AS, et al: Prevention of bacterial endocarditis: Recommendations by the American Heart Association. JAMA 277:17941801, 1997.
Neither is correct in my oppinion...Actually you are treating four surfaces of the teeth,mes, dis. incisal and lingual and you should bill only for those.However there is no such alternative so I think the right answer for this question would be A.
Hi Drpuri18
Remember why we use antibiotic prophylaxis for Dental Patients
"Prophylactic administration of antibiotics
is thus recommended for patients who run the
risk of endocarditis and on whom dental procedures
or oral manipulations likely to cause bacteremia are
performed" Oral Surgery
look at http://en.wikipedia.org/wiki/Endocarditis
what are the causes of myocardial infartion
http://en.wikipedia.org/wiki/Myocardial_infarction
From that we conclude that it is not necessary antibiotic prophylaxis for patients with myocardial infarction
cardiac conditions do not require endocarditis prophylaxis:
Negligible-risk category (no higher than the general population)
Isolated secundum atrial septal defect
Surgical repair of atrial septal defect, ventricular septal defect, or patent
ductus arteriosus (without residua beyond 6 months)
Previous coronary artery bypass graft surgery
Mitral valve prolapse without valvular regurgitation
Physiologic, functional, or innocent heart murmurs
Previous Kawasaki disease without valvular regurgitation
Previous rheumatic fever without valvular regurgitation
Cardiac pacemakers (intravascular and epicardial) and implanted
defibrillators
Dajani AS, et a!: Prevention of bacterial endocarditis: Recommendations by the American Heart
Association. JAMA 277:17941801, 1990.
