RESUMEN

Empathy is the fundamental substructure of moral behavior. Skillful clinicians may not necessarily be successful dentists if they do not have sufficient empathy. The aim of this study was to assess the level of empathy among dental students at King Abdulaziz University with an emphasis on the effect of gender and study level. A cross-sectional study was carried out among third- to sixth-year dental students of King Abdulaziz University in Jeddah, Saudi Arabia. A validated, self-administered Jefferson Scale of Empathy-Health Care Provider Student Version was distributed in academic year 2016-17 to all 380 students in the third to sixth years. A total of 300 students responded, for a response rate of 78.9%. The results showed that the students' mean empathy score was 84.84±11.28 on a range from 20 to 140. The fifth- and sixth-year students had higher scores than the third- and fourth-year students although the differences were not statistically significant. The mean empathy score of women students was significantly higher (p<0.001) than that of men students, and the women demonstrated significantly better perspective-taking (p<0.001) than the men. This study found that the students were empathetic and had a sense of moral obligation although their mean empathy score was not as high as expected. Integrating empathic, ethical, and professional elements into the dental curriculum is needed.

RESUMEN

Miconazole nitrate (MZ) is a BCS class II antifungal poorly water-soluble drug with limited dissolution properties and gastrointestinal side effects. Self-nanoemulsifying delivery system-based gel of MZ can improve both solubility and oral mucosal absorption with enhanced antifungal activity. The study aims to formulate MZ self-nanoemulsion (MZ-NE) and combine it within hyaluronic acid-based gel. MZ solubility in various oils, surfactants, and cosurfactant used in NE formulations were evaluated. Mixture design was implemented to optimize the levels of NE components as a formulation variable to study their effects on the mean globule size and antifungal inhibition zones. Further, the optimized MZ-NE was loaded into a hyaluronic acid gel base. Rheological behavior of the prepared gel was assessed. Ex vivo permeability of optimized formulation across buccal mucous of sheep and inhibition against Candida albicans were examined. Mixture design was used to optimize the composition of MZ-NE formulation as 22, 67, and 10% for clove oil, Labrasol, and propylene glycol, respectively. The optimized formulation indicated globule size of 113 nm with 29 mm inhibition zone. Pseudoplastic flow with thixotropic behavior was observed, which is desirable for oral gels. The optimized formulation exhibited higher ex vivo skin permeability and enhanced antifungal activity by 1.85 and 2.179, respectively, compared to MZ-SNEDDS, and by 1.52 and 1.72 folds, respectively, compared to marketed gel. Optimized MZ-NE hyaluronic acid-based oral gel demonstrated better antifungal activity, indicating its potential in oral thrush pharmacotherapy.

RESUMEN

BACKGROUND Dentigerous cysts are slow-growing odontogenic cysts that usually develop unilaterally as part of a pre-existing syndrome. Non-syndromic bilateral dentigerous cysts are extremely rare, but clinicians should be aware of this condition to ensure prompt diagnosis and management and to prevent complications. CASE REPORT A case is presented of bilateral mandibular dentigerous cysts that were discovered incidentally in a 44-year-old man who presented for extraction of a retained maxillary deciduous tooth. Histological examination of the tissue specimens following bilateral enucleation confirmed the diagnosis of bilateral dentigerous cysts. CONCLUSIONS In this case, incidental bilateral dentigerous cysts were identified and treated by enucleation. The absence of an associated syndrome should not exclude the possibility of the diagnosis of dentigerous cysts, which should be removed to prevent future complications.

RESUMEN

Background: Oral and maxillofacial lesions (OMFL) comprise a broad spectrum of benign and malignant lesions that affect the oral cavity. However, few epidemiological studies have evaluated oral cavity lesions, and very few have focused on oral soft tissue pathology. The purpose of this study was to identify the prevalence and distribution of OMFL that had been diagnosed histologically at the Oral Pathology Laboratory, Faculty of Dentistry, King Abdulaziz University. Materials and methods: A retrospective study was conducted to assess the distribution of OMFL among the oral cavity biopsies submitted to the Oral Pathology Laboratory during the period from 1996 to 2016. Information on sex, age, location of the lesion, and histopathologic diagnosis was analyzed. Results: A total of 1,218 cases were examined. Among these, reactive/adaptive lesions were the most common type (n=245; 20.1%) and cystic lesions were the second most common (n=214; 17.6%), followed by inflammatory lesions (n=152; 12.5%) and epithelial pathology (n=115; 9.4%). Conclusion: The results of the present study provide valuable information on the prevalence of OMFL in Jeddah, Saudi Arabia. Reactive conditions were the most frequently diagnosed pathologies. Most oral and maxillofacial biopsies were soft tissue lesions, benign in nature, and inflammatory in origin. Further studies are necessary to provide more information on head and neck diseases in the general population to develop better future oral health policies.
