The mode ofbond failure was evaluated by the adhesive remnant index (ARI). The data was analysed with T-testwhile ARI scores were evaluated by Wilcoxon test.Results: There was a significant difference between the two tested groups (P< 0.05).

There was nostatistically significant difference between the two preparation modes. There was no statisticallysignificant difference between Bond prep and cutting modes whether using GI (P-value = 0.433,Effect size = 0.014) or with RMGI (P-value = 0.051, Effect size = 0.085). Comparison between thetwo restorative materials revealed that GI showed statistically significantly lower mean shear bondstrength than RMGI whether using Bond prep mode (P-value <0.001, Effect size = 0.345) or cuttingmode (P-value = 0.001, Effect size = 0.226).Conclusion: Er,Cr:YSGG laser have adverse effect on the adhesion of RMGI and GI, bondprep mode is better than cutting mode and RMGI is preferred than GI clinically.  }, keywords = {Shear bond strength,Er,Cr:YSGG Laser,bond prep mode,resin modified glass}, url = {https://edj.journals.ekb.eg/article_78278.html}, eprint = {https://edj.journals.ekb.eg/article_78278_88b292051e1b16e0e748b03eefd53802.pdf} } @article { author = {Farag, Mohammed and El-Shakhawy, Medhat and El-Shennawy, Mahmoud and El-Mehy, Ghada}, title = {Comparison Between Bone Supported -Pendulum Appliance and Lever-arm Mini-implant System in Maxillary Molar Distali zation in Class II Malocclusion}, journal = {Egyptian Dental Journal}, volume = {64}, number = {Issue 4 - October (Orthodontics, Pediatric & Preventive Dentistry)}, pages = {3047-3056}, year = {2018}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2018.78280}, abstract = {Upper molar distalization with noncompliance therapies has become more popular in treatmentof Class II malocclusions.Purpose: This study was conducted to evaluate and compare the dentofacial changes afterdistalization of maxillary first molars using bone anchorage pendulum and Lever-arm mini-implantsystem in the treatment of dental Class II cases non-extraction cases.Subjects and Methods: The sample of this study was consisted of 30 patients of both sexes(16- 22 years old) divided into two groups. The first group consisted of 15 patients, their molar weredistalized with BAPA. The second group consisted of 15 patients, their molar were distalized withLAMS. The evaluation of the study was performed by detecting the changes on dental casts andlateral cephalograms.Results: All maxillary molars were distally moved into a super class I relationship successfullyin both groups (7.2 months in BAPA group and 10.5 months in LAMS group) and there was ahighly significant changes in the distal tipping of the maxillary first molar between the two groups,BAPA (22.8°) while the amount of distal tipping of the maxillary first molar in LAMS group was(10.29°).Conclusion: Both LAMS and BAPA appliances were effective, less invasive and compliancefree alternative for intraoral upper molar distalization without anchorage loss. Lever-arm and miniimplantsystem was effective for achieving absolute anchorage during the distal movement of uppermolars.  }, keywords = {Molar distalization,bodily distalization,classII malocclusion,bone anchorage pendulum appliances,lever-arm mini-implant system}, url = {https://edj.journals.ekb.eg/article_78280.html}, eprint = {https://edj.journals.ekb.eg/article_78280_8e898f048b73831b0fff94fcc60e3d0a.pdf} } @article { author = {Elbardissy, Adel and Mahmoud, Sara and Hamid, Asmaa}, title = {The Influence of Anterior Esthetic Fixed Appliance of Prematurel y Lost Primary Incisors on Sound Production In a Group of Egyptian Children.

The need for replacement of prematurely lost primary incisors with esthetic and functionalfixed or removable appliances were a subject for investigation in many literatures. The aim of suchappliances is to restore esthetics, preserve arch integrity and to prevent speech impairment.Aim of the study: to evaluate the Influence of anterior esthetic fixed appliance of prematurelylost primary incisors on sound production and speech intelligibility.Methodology: A case control study was conducted on 15 children (3-5 years old) with prematureloos of primary incisors (experimental group) and 15 children of similar age completely dentulous.Speech evaluation was examined in four stages: Before extraction of the decayed primary incisors.Before the modified fixed partial denture fitting. Immediately after denture fitting. One month afterdenture fitting.Results: sound production and speech intelligibility were not affected by premature loss ofprimary teeth. Minor affection after immediate placement of the fixed prosthetic appliance wasrestored in a period of one month as a result of adaptation.Conclusions: 1- Early loss of primary incisors due to caries would have minor effect on speechproduction 2- Replacement of prematurely lost primary incisors with fixed prosthetic appliancesdid not affect speech production 3- Replacement of prematurely lost primary incisors with fixedprosthetic appliances for the purpose of restoring appearance if required by the parents should beencouraged however, assuring that speech development will not be affected by early loss of theseteeth should also be explained to them if they are concerned.  }, keywords = {premature loss of primary incisors,speech intelligibility,speech production}, url = {https://edj.journals.ekb.eg/article_78281.html}, eprint = {https://edj.journals.ekb.eg/article_78281_5c2bf64615dc8d88d23367befb100fa3.pdf} } @article { author = {Rashid, Adel and Hamdy, Ahmed}, title = {The effect of resin infiltration on the color of white spot lesions after ort hodontic treatment over one year period (in vivo study)}, journal = {Egyptian Dental Journal}, volume = {64}, number = {Issue 4 - October (Orthodontics, Pediatric & Preventive Dentistry)}, pages = {3069-3073}, year = {2018}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2018.78282}, abstract = {Objectives: This study was carried out to evaluate the effect of a resin infiltrant in changingthe color of white spot lesion clinically, in addition to the color stability of the treated lesion overone year period.Methods: Fifteen post-orthodontic treated patients.

Crowns were examined for retention, gingival health,color match, contour and opposing tooth wear. Parental satisfaction with either type of crowns wasevaluated by questionnaire.Results: Seventy-seven crowns were evaluated in 32 children with 3 teeth lost to exfoliation.Crowns were examined 4-12 months after placement. Zirconia crowns showed a 100% retentiveness,color match, absence of gingival irritation, 94.7% cosmetic appearance with 100% overall parentalsatisfaction rated as very satisfied.
