Professional burnout is a long-term consequence of occupational stress. It is composed of emotional exhaustion, depersonalization, and reduced personal accomplishment. The aim of this study is to assess and measure burnout level among dentists and to investigate factors affecting it. A total of 370 questionnaires were distributed among practicing dentists in Riyadh and eastern area. The questionnaire consisted of demographic information and the Arabic version of the Maslach Burnout Inventory (MBI).

A total of 191questionnaire was returned with a response rate of 57.3%. Females constituted 57.1%, while males were 42.9%. The overall scores of the aspects of burnout were 42.4% high emotional exhaustion, 8.4% high depersonalization and 14.7% high lack of personal accomplishment. Younger dentists group, females, and general practitioners reported higher emotional exhaustion 43.2%, 71.6% and 43%, respectively. It is concluded that burnout is highly likely to occur in general dental practitioners, females, young dentists, increasing number of patients and increasing working hours and decreases with increasing years of experience.

Barodontalgia is defined as tooth pain occurring with changes in pressure environment. It affects mainly pilots and divers.

Aim: To measure the incidence of barodontalgia within pilots flying non-commercial war planes and divers practicing in air bases, naval base, and diving schools in Saudi Arabia & Kuwait.

Material and Methods: Questionnaires were distributed among pilots & divers that consisted of demographic data and questions about the occurrence of tooth pain during flight or diving.

Results: There was a response rate of 72.8% in Saudi Arabia and 80% in Kuwait. 33.6% of the sample had incidence of barodontalgia at one point in time during their practice. More pilots had an occurrence of pain while flying (49.6%) than did divers while diving (17.3%). Pilots had higher incidence of pain while ascending (30.4%) than descending (19.3%), while divers had higher incidence of pain while diving (13.9%) than resurfacing to sea level (3.6%). The highest percentage of tooth pain with pilots while flying with an altitude that ranged from 11,000-20,000 ft (3300-6000m) and with divers while diving with a depth that ranged from 60-80 ft (18-24m). Recurrence of tooth pain after treatment occurred in 16.4% of pilots and 25.0% of divers during their practice.

Conclusion: Barodontalgia is common in our society, the incidence is high (33.6%) overall. Pilots reported high incidence than divers. It is common on ascent while flying and descend while diving. Recurrence of pain after treatment was not frequent.

The purpose of the present study is to assess patients' satisfaction with their dental implants and the treatment outcome in Riyadh area, Saudi Arabia. The information regarding patients' opinion was collected through a self administered questionnaire distributed during recall appointments or filled through phone contact. Total of (111) subjects of different demographic variables who were treated in either governmental or private clinics and have the implant(s) for more than one year completed the questionnaire. Fifty-nine percent (59%) of the subjects were highly satisfied with the overall treatment. Seventy-one percent (71%) were highly satisfied with the esthetic and 78% were highly satisfied with function. About 77% were willing to undergo same procedure again and would recommend it to the others. Eighty-seven percent (87%) reported comfort with the treating dentist and 67% were satisfied with the preoperative information. On the other hand, fifth of the subjects found to be non-satisfied neither with the treatment period nor with its cost. It can be concluded that most of the patients were generally satisfied with the implant treatment and some variables like esthetic and time required for completion of treatment are critical for the overall satisfaction.

The aim of this study was to determine the effect of three different finishing and polishing systems on water sorption and weight changes (solubility and dislodgement) of micro-filled and hybrid composite after water immersion. A total of forty specimen discs measuring (15 mm x 2 mm) were prepared, 20 from each composite material; micro-hybrid composite (Herculite: HER) and micro-filled composite (Renamel: REN). Three polishing systems were used: the Enhance (ENH), Sof-Lex (SOF) and Astropol (AST) systems. Myler strip was used as the control group. The experimental methods for water sorption and solubility were based closely on the procedure recommended in the ISO specification (4049: 2000) and dislodgement was measured by weight changes. The results showed that HER material exhibited higher mean values in water sorption and solubility while REN showed higher mean values in the dissolution. ENH and AST systems had superior results with water sorption for both materials. SOF (3.79 ng/mm³) and AST (4.10 (xg/mm³) showed the lowest evidence of dislodgement in the micro-hybrid composite while SOF (4.85 ng/mm³) and ENH (5.31 |xg/mm³) had the lowest values with the micro-filled composite. According to the ISO Standard method of evaluating water solubility (4049: 2000), no water solubility was evident with neither (REN) nor (HER) resin materials. No statistical correlation was significant between the values for solubility and dislodgement. It was concluded from the study that the finishing and polishing treatments were important to maintain the weight of the composite resin restorative material in an aqueous environment.

070.An in-vitro investigation of the cytoxicity of recent gingival retraction materials

Several materials and techniques have been tried to achieve exposure of the tooth preparation finish lines and create an acceptable environment for the impression materials. Mechanical and/or chemical techniques are the most commonly used for gingival retraction. Gingival retraction materials should be biocompatible and well tolerated by the surrounding tissues. The objective of this study was to compare three recently introduced tissue retraction materials with regard to their cytotoxic effect on human gingjval tissue. The cytotoxic effect of those materials was judged using the cell viability test along with direct contact test and growth inhibition in an especially prepared culture at different time periods. The obtained results showed qualitatively that one of the investigated materials did inhibit the cell growth of the used culture media while the other two produced very slight growth inhibition of the cultured cells. Further, it was demonstrated that the conventional gingival retraction cord impregnated with adrenaline; Gingi-pak was the most toxic material among the tested materials at all time periods.
