To overcome stigmatization; different surgical techniques and modifications have been developed.<br />Objectives: comparing the effectiveness of rotation-advancement versus straight-line approaches in repairing unilateral cleft lip. <br />Methodology: Twelve patients with unilateral cleft lip were participated. These patients were equally divided into two groups; each group was operated on with Millard or Fisher incisions. Caliper measurements of the lip and nose were recorded preoperatively. The analysis was based on a quantitative and qualitative comparison of the cleft side versus the non-cleft side for 3 outcomes were used to assess the aesthetic difference between the two incisions; These outcomes were measured postoperatively at 6 months. Chi-square; Mann Whitney test was used for statistical comparison of outcomes.<br />The results: the nasal asymmetry improved in both groups with a better result in cases operated on with Fisher; which was statistically significant at (2.201* (0.028*). The medial lip height is increased in both groups, but was not statistically significant; the difference was statistically significant for the increase of lateral lip height of both groups at a P-value ofhttps://adjalexu.journals.ekb.eg/article_222340_c35656b8a2ac73bd2fa6e0a26529004b.pdfAlexandria University; Faculty of DentistryAlexandria Dental Journal1110-015X47220220801THE EFFECT OF ENAMEL PRETREATMENT WITH NANOSILVER FLUORIDE ON PIT AND FISSURE SEALANT IN PERMANENT TEETH (IN-VITRO STUDY)18919525068710.21608/adjalexu.2021.69685.1171ENRadwa MoatazOwnPediatric dentistry department,Faculty of Dentistry,Alexandria university,Alexandria,EgyptNadia A.WahbaProfessor, Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University, EgyptSally M.AbdelkaderProfessor of Dental Biomaterials Department, Faculty of Dentistry, Alexandria University, Alexandria, Egypt.Laila M.El HabashyAssociate Professor of Pediatric Dentistry, Faculty of Dentistry, Alexandria University, Alexandria, Egypt.Lubna M.EldesoukyAssistant lecturer of Department of Pharmaceutics, Faculty of Pharmacy, Alexandria University, Alexandria, Egypt.Journal Article20210329Introduction: Recently, Nanosilver fluoride (NSF) has raised in the field of caries prevention. Pit-and-fissure sealants could have an additional antibacterial and remineralizing benefit through enamel pretreatment by NSF.<br /> Objectives: to evaluate in-vitro the effect of NSF pretreatment on shear bond strength, marginal seal, and quantity of color change of pit and fissure sealant in comparison to sealant only in permanent teeth. <br /> Materials and Methods: Fifty-four freshly extracted permanent teeth were collected and randomly allocated into two groups: Group I: (n=27) NSF was applied to the enamel prior to sealant application. Group II: (n= 27) enamel was etched and sealed. Each group was divided into three subgroups according to the test applied. (n= 9 teeth each). Subgroup A: Shear bond strength was measured using a Universal Test Machine. The deboned area was examined under stereomicroscope to assess the mode of failure. Subgroup B: Microleakage samples were examined under a stereomicroscope to assess the degree of microleakage. Subgroup C: Color Assessment: After a sealant application, any change in sealant color was evaluated using a spectrophotometer.<br /> Results: no statistically significant difference between both subgroups neither in shear bond strength nor microleakage. The comparison of the final color of sealants in both subgroups showed a higher color change in subgroup Ic with a significant difference (P-value =0.001).<br /> Conclusion: Pretreatment with nanosilver fluoride prior to pit-and-fissure sealant application did not affect neither its shear bond strength nor its sealing ability. However, it altered the sealant color to an extent that exceeded the clinical acceptance levels.https://adjalexu.journals.ekb.eg/article_250687_f4eaae146ea50957de8a0a64f06de2ed.pdfAlexandria University; Faculty of DentistryAlexandria Dental Journal1110-015X47220220801EFFECTIVENESS OF SMART PHONE APPLICATION IN REDUCING ANXIETY DURING PEDIATRIC DENTAL PROCEDURES: A RANDOMIZED CONTROLLED TRIAL19620425068910.21608/adjalexu.2021.73371.1190ENGehad DerbalaPediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, EgyptAmani MohamedKhalilPediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, EgyptReham SobhiSolimanLecturer of Pediatric Dentistry, Faculty of Dentistry, Alexandria University, Alexandria, EgyptJournal Article20210427Introduction: Numerous dental health programs are directed at reducing the anxiety of children. Smartphone applications may be beneficial in behavior management problems when undergoing dental procedure.<br /> Objectives: The aim of this research was to determine the effectiveness of smartphone applications (Tell-Play-Do) (TPD) in reduction of preoperative anxiety in children who are undergoing restorative treatment in comparison with the Tell-Show-Do (TSD) technique.<br /> Materials and Methods: This research was a randomized controlled clinical trial. A sample of 38 healthy children patients per group (number of groups=2) with age ranging from 6-8 years were assigned from the outpatient clinic of the Department of Pediatric Dentistry and Dental Public Health. All participants were randomly distributed to one of two groups: TPD or TSD. They All required restorative treatment with carious maxillary primary molars (class I only) without-pulpal involvement and infiltration of local anesthesia (LA). Dental anxiety was assessed by using Venham's picture test (VPT) and heart rate (HR) in three steps (baseline, after intervention TPD/TSD and after treatment). <br /> Results: The reduction in dental anxiety scores(VPT) after applying the TPD in comparison with the base line scores for the test group exhibited statistical significance (P1<0.0001), while it was statistically non-significant in the control group (TSD technique). Both groups showed reduction in HR pre-operative and post-operative, however, the reduction was almost doubled in TPD group using dental application.<br /> Conclusions: In pediatric patients, the Tell-Play-Do technique by using smartphone application is an effective instrument for reducing dental anxiety.https://adjalexu.journals.ekb.eg/article_250689_082bd87eb4d7be1ad69bb916160d5d95.pdfAlexandria University; Faculty of DentistryAlexandria Dental Journal1110-015X47220220801EVALUATION OF BOND STRENGTH OF HYDROPHILIC PIT AND FISSURE SEALANTS (IN VITRO STUDY).20521125069010.21608/adjalexu.2021.73642.1191ENHagar ZaghloulDepartment of pediatric dentistry and dental public health, Faculty of dentistry, Alexandria university, Egypt0000-0003-3349-1339Amina MAbdelrahmanProfessor, Department of pediatric dentistry and dental public health, Faculty of dentistry, Alexandria university, EgyptNiveen S.

Numerous methods are used to control dental anxiety in children. Audiovisual distraction using virtual reality (VR) glasses is a non-pharmacological intervention that can be used to manage child’s anxiety during dental treatment.<br /> <br /> Objectives: To evaluate and compare the effect of VR glasses to conventional behavior management techniques on child’s anxiety during pulpotomy.<br /> <br /> Methodology: The study was a randomized controlled clinical trial. The sample consisted of twenty preschool children of age ranging from 4 to 5 years old presented to the Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University. The selected children had at least one mandibular primary molar indicated for pulpotomy. The eligible participants were randomly and equally divided into an experimental group, where VR glasses distraction was used for child behavior management and a control group, where conventional behavior management techniques were used. Pre and post-operative assessment of child’s dental anxiety was done using (a) Venham clinical anxiety rating scale (b) Changes in salivary cortisol level. <br /> <br /> Statistical Method: Mann-Whitney test, Friedman test, and Wilcoxon signed rank test were used. Significance level was set at P value < 0.05.<br /> <br /> Results: The VR group showed significantly lower scores for Venham clinical anxiety rating scale than the control group during intraoral examination (P=0.02). However, there were no significant changes in salivary cortisol level in any of the groups.<br /> <br /> Conclusion: VR glasses were useful in managing dental anxiety in preschool children especially during intraoral examination.https://adjalexu.journals.ekb.eg/article_250691_1363ae1926b15a65fb9b43c501f5aa4b.pdf
