DESIGN: After random allocation of thirty healthy male Wistar albino rats into three groups (10 per group), in group 1 {control group} animals received saline, whereas those in group 2 {the tacrolimus (TAC) group} received daily subcutaneous injections of the immunosuppressant for 3 weeks. In the third cohort group 3{tacrolimus and activated charcoal; TAC+AC}, rats received activated charcoal orally administrated beside the TAC for 3 weeks. After three weeks of treatment, the evaluation of dissected tongues exempted histological, immunohistochemical, and morphometrical analyses. RESULTS: Histological findings revealed mucosal and connective tissue degenerative changes induced by TAC. However, the AC group showed the preserved structure of the lingual mucosa and associated minor salivary glands. The immunohistochemical detection of Melan-A revealed the profound drop in the mean area percent and optical density of melanophages to 0.82 ± 0.2% and 0.12 ± 0.01, respectively, upon AC counteraction of TAC melanosis. CONCLUSIONS: AC exerted protective action against the degenerative effect of TAC on the lingual mucosa, encouraging its adjuvant uptake throughout the immunosuppressants course.","PeriodicalId":7723,"journal":{"name":"Alexandria Dental Journal","volume":"57 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139536083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, mechanical debridement results in smear layer formation containing infected debris requiring its removal before obturation. AIM OF THE STUDY: To assess the efficacy of Morinda Citrifolia juice (MCJ) as final irrigation protocol associated with manual dynamic agitation on smear layer removal by using scanning electron microscope. MATERIALS AND METHODS: Forty-five human mandibular permanent premolar teeth with single canals were decoronated to a standard length of 15mm and instrumented using ProTaper Next rotary files (X3). Roots were divided into 3 equal groups (n=15) according to the final irrigant used: Group I: 6% MCJ, Group II: 6% MCJ + 17% EDTA, Group III (control group): 2.5% NaOCl + 17% EDTA. Manual dynamic agitation (MDA) was used to activate the irrigants in all groups. Teeth were then prepared for scanning electron microscopy evaluation, and smear layer removal was assessed.. Comparisons between the study groups were done using Kruskal Wallis test, while comparisons of different regions within each group were done using Friedman test. RESULTS: Along complete canal length, no significant difference was found between 6%MCJ+17% EDTA and 2.5% NaOCl + 17% EDTA (p=0.29). However, a significant difference was noted between 6%MCJ and 2.5% NaOCl + 17% EDTA (p=0.001). In all groups, the coronal third showed the best results (P = 0.02) and the apical third showed the worst (P = 0.007).

AIM OF THIS STUDY: Radiographic evaluation of a combined technique using autogenous dentin graft with socket shield for pre-implant socket preservation Patient and method: Eight patients received socket preservation using alloplast with socket shield on one side and received socket preservation using Autogenous dentin graft with socket shield on the contralateral side (split-mouth Design).

Since antioxidant integration is considered as the most effective therapy sesame oil has been recommended for preventing lead-induced poisoning. The purpose of this research is to examine the ultrastructural changes that may develop in the acini and duct system of the parotid salivary glands of adult albino rats after exposure to lead acetate, and to identify the possible protective effect of sesame oil. MATERIALS AND METHODS: This research included 24 adult male albino rats weighing between 180-200g. Randomly, the rats were separated into three equal groups: Group I (Control), Group II (Lead acetate), and Group III (Lead acetate + Sesame oil). After five weeks of experimentation, blood was drawn and tested using atomic absorption spectroscopy (AAS) to determine the blood lead level. After euthanization, glands were dissected for transmission electron microscopy analysis. RESULTS: Group (II) blood results demonstrated a rise in blood lead levels, but group (III) blood lead levels were midway between groups (I) and (II), demonstrating the therapeutic impact of sesame oil. Group (II) revealed acinar cells with evidence of cytotoxicity, including degenerated mitochondria, apoptotic nuclei, whereas the ducts had lumens with stagnant secretion. The ultrastructure of their acinar cells and duct system improved significantly in group III.

Therefore, the introduction of additives such as Botulinum Toxin (BoNTA) to promote fat graft survival was taken into consideration and initially assessed in a rabbit model. Aim of the study: Is to evaluate histologically and histomorphometrically the effect of BoNTA on the survival rate of fat graft. MATERIALS AND METHODS: We used 15 rabbits in each group. Each rabbit had two incision lines made in its lips as recipient sites, and fat tissue was extracted from the donor site—the scapular adipose sacs—by cutting those incision lines. There were two sets of lips on each of the rabbits: one set was for the control group, and the other study group. The control group merely received a fat transplant with 0.5ml of saline, while the experimental group received a fat graft with 5 units of BoNTA. Five rabbits were scarified at the 3, 6, and 9-week postoperative testing intervals. The upper lip was dissected for a light microscopic analysis and histomorphometrical investigation. RESULTS: Histological evaluation showed that injection with BoNTA improved survival rate and vascularization of fat graft. In comparison to the control group, the study group's percentage of the surface area of the fat graft rose statistically significantly at 3, 6 and 9 weeks (P <0.001), according to histomorphometrical analysis.

OBJECTIVES: Assessment of CBCT referral reasons to private radiology centers, and its impact on modifying treatment plan in endodontic and endo-periodontal related cases. MATERIALS AND METHODS: This cross-sectional study comprised a total of 131 patients, who visited private radiology centers in Alexandria, seeking CBCT scans, from July 2021to June 2022: All scans were inspected for assessing referral reasons; referring dentists were asked about their reason for CBCT acquisition, and its effect on their diagnosis and treatment plan.
