Methods: A total of 22 adult patients (mean age, 19.78 + 1.24 years) with Class II division 1 malocclusion were randomly assigned to 2 groups; group I (11 patients treated with miniscrew anchored en-masse retraction) and group II (11 patients treated with two-step retraction using conventional anchorage). Skeletal, dentoalveolar and smile changes were analyzed in both groups using standardized photographs, study casts, and lateral cephalograms before and after space closure. Results: Miniscrew anchored en-masse retraction showed a statistically significant decrease in upper incisor display (U1UL) (-2.22±1.33; P<0.05). There was a significant increase in nasolabial angle (-13.6±8.09, P≤0.001; 6.6±5.93, P=0.007) for group I and II, respectively. Non-significant difference was found in buccal corridor and smile arc measurements in both groups (P>0.05). Group II demonstrated a statistically significant decrease in IMW (-1.63 ± 1.19, P<0.05) and significant mesialization of maxillary first molars (U6-MR, U6-LR) (-2.46 +1.64, -1.03 + 1.13, P˂0.05). Conclusion: The use of miniscrews as a means of anchorage during retraction of maxillary anterior teeth provides an absolute anchorage for maxillary first molars with in either anteroposterior or vertical direction. Therefore, it could effectively reduce upper incisors display without altering buccal corridor dimensions or affecting the smile arc.}, keywords = {Dental arch,SMILE,buccal corridor,miniscrew,en-masse retraction}, url = {https://edj.journals.ekb.eg/article_197161.html}, eprint = {https://edj.journals.ekb.eg/article_197161_191cc5151e1f01aff0bde6ddb2ffb0d6.pdf} } @article { author = {Awad, Mohammad and Attia, Nasr and Salem, Nanees}, title = {Oral Health Assessment in Children and Adolescents with Type 1 Diabetes}, journal = {Egyptian Dental Journal}, volume = {67}, number = {4}, pages = {2853-2864}, year = {2021}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2021.77985.1650}, abstract = {Abstract: Objective: To assess oral health status in relation to diabetes-related variables in a cohort of children and adolescents with type 1 diabetes mellitus (T1DM).

Results: Significantly higher frequency of patients had fair oral hygiene and moderate gingivitis (P<0.001). Significantly lower stimulated salivary flow rate was detected in patients within late childhood group (P=0.038). Increased prevalence of permanent dental caries was observed in late adolescent period (P=0.001). There was significant increase in primary dental caries in children diagnosed with diabetes before six years (P=0.004). Patient´s age was positively correlated with SSFR, gingival-index and DMFT-index. DMFT-index was positively correlated with T1DM duration and HbA1c level. There was significant positive correlation between OHI-S and GI. Conclusion: Children and adolescents with T1DM displayed unfavorable oral health profiles that have been strongly linked to patient´s age, age at onset and duration of T1DM and level of metabolic control.

Subjects and methods: This cross-sectional study was conducted on a sample of 512 dental students; undergraduates (level 10, 11, and 12) and dental interns. Representative samples were collected from different governmental and private dental colleges in KSA. A questionnaire of 10 items was created on Google forms and distributed to the dental students. Results: from the 10 knowledge questions only two questions were correctly recorded by more than 50% of the participants, there were no significant differences between private and governmental, male and female as well as among different academic levels for all questions regarding Knowledge about TMDs. Also, there were no association between knowledge level and gender or academic levels of the participants, but college type was positively associated with knowledge level of the students. Conclusion: Knowledge level about TMDs was insufficient among undergraduates and dental intern students, and the mean knowledge score was roughly increased by increasing students' academic years.

A comparable proportion preferred a treatment duration of 5-7 days. Although, 96% of the responses came in favor of antibiotic prescription in serious clinical conditions as facial cellulitis, still variable proportions of the sample chose to prescribe antibiotics for conditions that do not necessitate their usage as “localized intra-oral abscesses”, “sinus tracts and fistulas”, “luxation injuries” and “managing viral infections”.  Conclusions: Although the participants showed considerably adequate knowledge of the bacterial resistance problem, their practices showed varying degrees of deviation from the guidelines of antibiotic prescriptions set by the AAPD.}, keywords = {Antimicrobial resistance,Antibiotic prescription,prescription,Mis-use}, url = {https://edj.journals.ekb.eg/article_197173.html}, eprint = {https://edj.journals.ekb.eg/article_197173_2b121f853ebae58c8cb9d465ef27ecf7.pdf} } @article { author = {Hamed, Mohammed and Elsherbini, Mohamed and Elborolsy, Samir}, title = {Investigation of The Effectiveness of Using Virtual Reality as A Distraction Technique in Children During Local Anesthesia Injection For Extraction of Primary Mandibular Molars}, journal = {Egyptian Dental Journal}, volume = {67}, number = {4}, pages = {2905-2913}, year = {2021}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2021.85045.1709}, abstract = {ABSTRACT Background: Local anesthesia injection for tooth extraction of primary molars is one among the causes of avoiding dental visits in children. Voice control and hand over mouth exercise are invasive and considered the least accepted techniques, a more accepted technique for children and their parents was needed.

Material and Methods: A prospective, parallel two arms randomized; clinical trial was performed on seventy-two children. Patients were (7-11) years old with unilateral carious non-restorable mandibular primary first molars required local anesthesia (LA) for extraction. Group (A) received treatment wearing virtual reality (VR) device and Group (B) received treatment using tell, show and do behavior management technique. Anxiety levels were measured using heart rate (HR) measuring before and after the injection while pain perception was assessed immediately after the injection using the Face, Legs, Activity, Crying and CONSOL ability scale (FLACC)and Facial Image Scale (FIS).

This introduces canine distal tipping and mesiobuccal rotation. The correction of these unwanted movements will prolong treatment time. Applying the force closer to the center of resistance should decrease this unwanted tooth movement. Objective: Compare the canine angulation and rotation during canine retraction with and without the use of power arm. Materials and Methods: Twenty-four female orthodontic patients (age 19.32± 4.17 years) with dental Class II indicated for bilateral maxillary first premolar extraction and maximum anchorage were included in this study. The canines were retracted with elastomeric chains over 0.016” X 0.022” statinless steel arch wires to reduce friction. The retraction force was 150g. In twelve patients, the canines were retracted using a power arm fixed to the vertical slots of the canine brackets. For the other twelve patients, the elastic chains were attached to the bracket hooks. Results: Before treatment, the canine angulation and rotation was similar for the two groups. The canine angulation was 12.38± 8.27 and 14.5º± 9.41 for the group with the power arm and without, respectively. while canine rotation was 64.74º± 11.65 and 63.12º± 14.88, respectively. Post-retraction, there was no significant difference in the canine angulation or rotation between the groups. Conclusion: Compared to canine retraction with a power arm, conventional canine retraction with elastomeric chains attached to the bracket hook may provide similar control over distal tipping, provided a stiff 0.017” X 0.025” stainless steel arch wire is used.}, keywords = {canine retraction,power arm,canine angulation,canine rotation}, url = {https://edj.journals.ekb.eg/article_197178.html}, eprint = {https://edj.journals.ekb.eg/article_197178_ebe1dd7fd5a42856d1764ad2833c3049.pdf} }
