Thermocycling As A Means Of Inducing Mechanical Fatigue In Dental Composites, Noor Hayaty Abu Kasim Abu Kasim N.H. May 1998

Thermocycling As A Means Of Inducing Mechanical Fatigue In Dental Composites, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

The effect of thermocycling on the fatigue behaviour of 5 commercially available dental composites; P50(P)1, Silux Plus(S)2, Heliomolar(H)3, Clearfil Photo Posterior-light activated(CLA)4 and Clearfil Posterior-chemically activated(CC)5 was investigated. One hundred and ten rectangular bar specimens were prepared for each materil and divided into 11 groups of 10 each. Test groups 1-6 were subjected to 0, 250, 500, 750, 1000 and 1000 thermal cycles respectively. Each thermal cycle consisted of 1 minute immersion time of 50 seconds per change. The control groups 7-11 were stored in distilled water at 370c for the equivalent time to complete 250, 500, 750, 1000 and …


Aging And Diabetes Mellitus: A Dental Public Health Problem Along The Us-Mexico Border, Frank Cortez Flores Jan 1998

Aging And Diabetes Mellitus: A Dental Public Health Problem Along The Us-Mexico Border, Frank Cortez Flores

Frank Cortez Flores

My primary dental public health interest is highlighting the importance of oral infections in patients with diabetes mellitus. The goal of the diabetes lecture (Oral Health Lectures Series) is to promote the early recognition of Type 2 Diabetes Mellitus (Type 2 DM) and improve the understanding of diabetic risk factors involved in the prevention, surveillance and control of oral infections. Type 2 diabetes, a non-communicable disease, is a major public health problem affecting certain ethnic groups. The theme of the lecture/presentations is awareness and learning. Although space constraints does not allow addressing every infection that is seen in patients with …


The Radiopacity Of Dental Prostheses (Fixed And Removable) On Plain Radiographs-An Experimental Study, Noor Hayaty Abu Kasim Abu Kasim N.H. Jan 1998

The Radiopacity Of Dental Prostheses (Fixed And Removable) On Plain Radiographs-An Experimental Study, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

The impaction of dental prostheses in either the airway or esophagus is an under-recognized problem which may result in severe morbidity or even mortality. The radio-opacity and the size of fixed and removable dental prostheses in an animal carcass was investigated. Prostheses were placed one at a time in the oro-laryngopharynx or in tho trachea and the esophagus. Lateral radiographs were taken for each prosthesis in site. The radio-opacity and size of the prostheses on the radiograph was graded. Most of the prostheses investigated were radio-opaque though the removable prostheses were more likely to be radiolucent and differ in size. …
