Iranian Dentists’ Knowledge of Post-exposure Prophylaxis Against HBV, HCV, and HIV

Avicenna Journal of Dental Research (2020)

Maryam Amirchaghmaghi Hooman Keshavarz Farid Haghdadi

Background: Dentists are at higher risk of exposure to blood-borne pathogens including HBV (hepatitis B virus), HCV (hepatitis C virus), and HIV (human immunodeficiency virus). The aim of this study was to evaluate the knowledge about post-exposure prophylaxis (PEP) against HBV/HCV/HIV among the general dentists working in Mashhad in 2016. Methods: This cross-sectional study was conducted on a random sample (141 persons) of the general dentists working in Mashhad. The data gathering tool in this study was a self-administered questionnaire. The validity of the questionnaire was assessed by a group of relevant specialists. The reliability of the questionnaire was also tested by a test-retest method with a two-week interval. The agreement between the two steps (test and retest) was at least 70%, and Cronbach’s alpha was 0.74. The total score of each person’s knowledge ranged from -20 to +20. One-way analysis of variance (ANOVA) and t test were used for statistical analyses. Results: Out of 141 dentists selected randomly, 101 subjects (69.3% male) participated in the study. The mean age of the participants was 42.3 years, And the mean duration of dental practice experience was 16.3 years. Regarding the mean age (P = 0.11), and the mean duration of dental practice experience (P = 0.12), there was no statistically significant difference between the two genders. The mean score of knowledge among the participants was -2.8, and there was no statistically significant difference between the two genders in this regard (P = 0.72). Conclusions: This study indicated that the level of knowledge about PEP against HBV/HCV/HIV was very low among the general dentists working in Mashhad. Therefore, improving knowledge of general dentists working in Mashhad through appropriate educational interventions seems necessary.

Conservative Management of Horizontal Root Fracture: A Case Report

Clinical Case Reports (2024)

Farid Haghdadi Amirreza Mokabberi Seyed Ahmad Banihashem Rad

In cases where permanent teeth have closed apices and completely erupted roots, the probability of root fractures is increased due to the stable support given by the adjacent bone and periodontal tissues. Fractures have the potential to affect several dental structures, including the pulp, dentin, cementum, bone, and periodontal tissues. In cases of horizontal root fractures (HRF), the apical section typically maintains vitality; however, the present case presented an unusual apex necrosis. Given the patient's age and tooth stability, traditional apical surgery was deemed inappropriate. Instead, a conservative treatment approach was chosen to preserve the tooth. This case report details the management and a 2-year follow-up of a maxillary central incisor exhibiting a HRF and apical necrosis, successfully addressed through the application of Mineral Trioxide Aggregate (MTA) in the both apical and coronal segments. Using MTA prevented apical surgery in cases of apex necrosis accompanied by HRF.

Evaluation of Stability in Short Implants Compared to Standard Implants using Periotest ®: A Pilot Study

DOAJ (DOAJ: Directory of Open Access Journals) (2020)

Introduction: Among different non-invasive approaches for determining the stability of the implant within the bone is to use a dynamic device called Periotest®.It is designed to provide objective measurement of tooth mobility. The aim of the present study is to evaluate the stress transfer and stability in short and standard dental implants using Periotest® device. Methods: This study evaluated 15 short and 15 standard implants for non-systemically compromised patients who were candidates for dental implant. After the implant insertion, the Periotest Value (PTV) index was measured by the Periotest® device in two periods, three month after implant installation when the healing abutment was placed and six months after permanent restoration. The stability was measured by Periotest®, and the obtained numbers were analyzed by the Wilcoxon test. Results: The mean values of PTVs in the group of short implants were as much as -1.13±0.91 and -1.46±0.91 before and after loading, respectively. Moreover, the mean values of PTVs in the standard implant group were as much as -1.6±1.12 and -1.8±0.67 before and after loading, respectively. The difference between short implants before and after loading was not significant. Furthermore, the PTVs in standard implants showed no significant difference before and after loading. Also there was no significant difference between short and standard implants at both times before and after loading. Conclusion: There is no significant difference between short and standard implants in terms of stability; therefore, they can be a good alternative to standard implants in atrophic jaws.
