ABSTRACT
Introduction: Due to the increased prevalence of medically compromised patients who require dental treatments, it is a crucial task for dentists and dental specialists to prepare themselves for emergent professional situations. This study was performed to determine the prevalence of different medical problems among a population of patients admitted to a dental educational center. Materials and Methods: In this prospective study, the prevalence of medical problems in patients [n = 968] referred to the Department of Oral and Maxillofacial Surgery of the School of Dentistry of Tehran University of Medical Sciences, Iran, was investigated for 3 consecutive months. Result: Among all patients, 397 were medically compromised patients. The mean age of the patients was 48 +/- 0.15 and 51.4% were men. The results showed that 41% of the patients had at least one medical problem. The two most common diseases were hypertension [13.9%] and diabetes mellitus [6.3%], respectively. The majority of patients with medical problems were referred from private dental offices. The majority of patients [97%] had well-controlled systemic diseases that could be treated in a private office. Conclusion: This investigation showed the necessity of teaching the management of medically compromised patients in dental school curriculum and in continuous dental education programs
ABSTRACT
Implant stability of different designs have shown to be variable. The aim of this study was to evaluate the stability changes as a reflection of early healing around roughened-surface implants in human using resonance frequency analysis [RFA]. 153 Branemark Replace tapered Ti-unite[tm] implants in 68 patients were placed in the maxilla or mandible. Bone type was classified into one of 4 groups according to Lekholm and Zarb index. RFA was used for direct implant stability measurement on the day of implant placement and at 14, 30 and 60 days after placement. No early failure occurred. The lowest primary stability measurement was observed in type 4 bone. Student t-test for comparison of bone groups at each time point revealed no significant difference between implant stability in all bone types [P > 0.05]. In testing the effect of implant length and diameter with time using the mixed model ANOVA according to implant length, there was not any significant difference between groups [P > 0.05]; however, implant diameter showed a significant effect on implant stability. There were no significant differences in implant stability between genders [P > 0.05], According to the results, pattern of stability changes are not different among different bone type
