Factors affecting the usage of removable partial dentures (RPDs) are still controversial. Since the RPD usage is partly related to patients’ personality, variations among different population is expected. This study aimed to evaluate the factors that influence the RPDs denture usage in patients of undergraduate students of Damascus University by using telephone call one-year after delivery.

It is necessary when designing removable partial dentures to be fixed, stable and well supported for improving patient comfort, and decreasing damages on soft tissues and dental abutments, the alveolar ridge has a strong influence in planning for treatment and interpretations biomechanical when treated with removable partial dentures, and have four shapes in the sagittal plane which are horizontal shape, concave shape, distal ascending shape and descending shape.
The initial retention of implant-supported removable partial dentures(ISRPD) is unknown. the purpose of this in vitro study was to compare maximum dislodging forces of distal extension mandibular ISRPD with three different clasp design. a stimulat ed class 1 partially edentulous mandible was prepared with two implant in the first molar regions and two metal ceramic on distal abutments. Fifteen bilateral distal extension frameworks was fabricated with three different clasp design (Akers, I bar clasp ,no clasp),each specimen was subjected to three type of retention pulls ( main ,unilateral ,posterior pulls) five time with universal testing machine.
The aim of study: to determine the prevalence and probable predisposing factors of RAS among the dental students (as thought by patients ) . the study was cross- sectional one , carried out on 115 students of dental school of Damascus University , data was collected by filling a questionnaire .
This study was conducted in Neonatal Intensive Care Unite of Children Hospital of Damascus University from 1/6/97 to 31/12/97. The study led to the following results: 1485 admissions over the inducated period resulted in 790 death cases. The mort ality rate was 53.19%. Masculinity, prematurity, low-birth weight and the general bad condition at admittance are the major risk-factors. There was no clear effect of controlled or uncontrolled pregnancy, location of delivery and patient transport on the mortality rate. Infectious diseases are the main cause of mortality, followed by respiratory diseases, congenital malformation, neurologic diseases, surgical conditions and heart diseases respectively.
