It was a randomized, double-blind, and controlled study. Twenty-six (stage III) periodontitis patients, with (three-wall) intrabony defects, were randomly divided (Thirteen in each group) into test (EPO gel + xenograft) and control (xenograft alone) groups. The primary outcome was evaluating the changes in the periodontal parameters; the plaque index (PI), sulcular bleeding index (SBI), probing depth (PD), and clinical attachment level (CAL) and wound healing by the Early Healing Index (EHI). The secondary outcome was evaluating the changes in the radiographic parameters including the defect fill (DF) and alveolar crest changes. Results: After the first and second weeks, the test group demonstrated a significant EHI reduction than the control group. At six months, there was a significant gain in CAL and DF in both groups with a significantly lower CAL gain and DF in the test group compared to the control group. There was a significant PD reduction with no significant difference between both groups. Conclusion: EPO gel as an adjunct to xenograft may accelerate soft tissue healing after surgical management of intrabony defects. However, it does not enhance the xenograft regenerative outcomes.","PeriodicalId":505319,"journal":{"name":"Ain Shams Dental Journal","volume":"68 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141276800","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}

Each patient received a dental implant with 10.5 mm length and 3.8 mm diameter at the canine region of the contralateral side of the mandible. The patients were divided into two groups according to the type of attachment used (n=7); BC group included patients who received mandibular over-dentures retained by bar clip attachment supported by an implant on one side and a natural tooth on the other side. BS group involved patients who received a mandibular implant splinted to the natural canine by bar joint attachment utilizing soft liner material. The patients of both groups were rehabilitated with conventional maxillary complete dentures. Clinical and radiographic assessment were performed immediately after over-denture delivery, six and twelve months from denture insertion. Clinical evaluation involved gingival index. Radiographic evaluation included measuring mesial, distal, buccal and lingual bone height differences. Results: BC group recorded significantly higher bone loss compared to BS group around both dental implants and natural teeth.

It also evaluated the influence of parental general anxiety on children's anxiety during this visit. Materials and methods: Eighty-eight children, aged 6–12 years, who had never visited a dentist before were conveniently recruited. Recruited children were subjected to the Wechsler Intelligence Scale for Children III (WISC III) and the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) to examine their IQ and dental fear and anxiety, respectively. Concerning parental general anxiety, General Anxiety Disorder-7 (GAD-7) was utilized. Children’s behavior at their first dental visit was assessed utilizing Frankl's behavior rating scale. The Arabic-validated versions of WISC III, CFSS-DS, and GAD-7 were used. The correlations were examined using Spearman's rank-order correlation coefficient (P<0.05). Results: There was a negative correlation between children’s IQ score and their DFA levels. There was a positive association between children’s DFA and their parent’s general anxiety levels. There was a favorable positive correlation between the degree of cooperation and the children’s IQ scores during their first dental visit. Conclusion: This study reveals the common occurrence of fear and anxiety in children during dental visits between the ages of 6 and 12. The findings highlight the complex interplay between cognitive abilities, parental influence, and dental experiences in children. It emphasizes the importance of addressing both child and parental anxiety to promote positive dental visits.","PeriodicalId":505319,"journal":{"name":"Ain Shams Dental Journal","volume":"57 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141275817","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}

Materials and methods: The study included three main groups: unmodified Biodentine, 5% wt CaF 2 -modified Biodentine , and 10% wt CaF 2 -modified Biodentine . The antibacterial activity of the tested cement was evaluated against the three bacterial strains through direct contact and agar diffusion tests. Fluoride release in deionized water at different intervals (1 day, one week, and one month) was assessed using ICP-MS. Results: The direct contact test revealed that the different experimental biodentine groups had lower optical density than the bacteria groups after one day, which was confirmed at seven days. The 10% group showed a significantly higher antibacterial effect against S. mutans and L. acidophilus than the other biodentine groups. The agar diffusion test showed significant differences between groups regarding Streptococcus mutans and Lactobacillus acidophilus . The positive control group had significantly higher inhibition zone values than the 5% CaF 2 -modified and unmodified Biodentine groups. The 10% CaF 2 -modified group showed no statistically significant difference compared to the positive control. For Enterococcus faecalis , the positive control exhibited a significantly higher value than other groups. None of the experimental groups showed inhibition zones against Enterococcus faecalis . Conclusions: Adding 10% CaF 2 to Biodentine could improve its antibacterial effect against S. mutans and L. acidophilus. However, its effectiveness against Enterococcus faecalis is questionable. The addition of 10% CaF2 also offers fluoride-releasing qualities to Biodentine.","PeriodicalId":505319,"journal":{"name":"Ain Shams Dental Journal","volume":"60 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141281009","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}

Materials and methods : Forty extracted primary incisors were collected, prepared, and then obturated using Metapex. Teeth were allocated into four groups. Group (A): teeth restored with human dentin posts; Group (B): bovine dentin posts; Group (C): glass fiber posts; and Group (D): orthodontic stainless-steel wire in omega-form posts. Dentin blocks were obtained from the roots of extracted human maxillary premolars and bovine permanent incisors to fabricate the dentin posts. These blocks were formed into post shapes using a Computer Numerical Control (CNC) machine. The posts underwent cementation using glass ionomer cement, followed by coronal buildup with composite. After thermocycling, the FR and mode of failure were examined. The FR was analyzed using the Kruskal-Wallis test, while the mode of failure was analyzed using the Monte Carlo test. P-values ≤ 0.05 were used to determine statistical significance. Results : The median maximum compressive load in group (A) was 386.87 N, in group (B) it was 379.27 N, in group (C) it was 522.16 N, and in group (D) it was 469.14 N.

Materials and Methods: Calcium Hydroxide (CH) and nano calcium hydroxide (NCH) powders were initially characterized using transmission electron microscope (TEM), X-ray Diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and a zeta sizer instrument. Standard dentin discs were prepared, irrigated according to the Regenerative Endodontic Procedures (REP) protocol, then treated with 1 mg/ml of CH or NCH pastes, and incubated for 1 week. Untreated discs served as control. Then, they were washed off, and all discs were treated with 17% EDTA before seeding of human periodontal ligament stem cells (hPDLSCs) . Cell viability was assessed using MTT assay. Mineralized nodules and alkaline phosphatase (ALP) activity were determined to assess cell differentiation. Cell dentino/cementogenic and osteogenic potential were assessed through monitoring gene expression levels Dentin sialophosphoprotein (DSSP), Cementum protein 1 (CEMP1), Runt-related transcription factor 2 (RUNX2), Osteoprotegrin (OG), and Osteocalcin (OC) using RT-qPCR. Results: TEM examination of NCH powder particles revealed a regular pattern and hexagonal shape with side dimension up to 60 ±10 nm. XRD analysis of NCH powder demonstrated its highly crystalline nature. FTIR spectroscopy confirmed that CH and NCH consisted mainly of pure calcium hydroxide. The zeta sizer instrument showed that NCH is positively charged with an average zeta potential of +27.8 mV. hPDLSCs seeded on NCH-treated discs showed significantly higher cell survival , more mineralization, higher alkaline phosphatase activity and increased expression of DSPP, CEMP1, RUNX2, OPG and OC markers.
