Background: Approximately 2,56,000 children and young adults around the world developed acute lymphoblastic leukemia (ALL) which is the most common subtype of Leukemia. The aim of our study was to investigate the effect of acute lymphoblastic leukemia on salivary alterations in children before and after chemotherapy induction. Materials and methods: This study included 45 children aged from 5 to 9 years. The sample was divided into 3 groups: Group A (control group); clinically healthy un-medicated children, Group B: children with a previous diagnosis of ALL and did not initiate the chemotherapy treatment and Group C: hospitalized children with a previous diagnosis of ALL and who were on chemotherapy (6 months-1.5 years of treatment). From the selected children, stimulated whole saliva samples were collected in graduated tubes with funnels over a 5 minute period in the morning. Saliva samples were used to determine the stimulated salivary flow rate, salivary pH, salivary total proteins and salivary alpha amylase. Results: The results showed a significant reduction in the mean of salivary flow rate values between (group A) and (group C), also the difference was significant between (group B) and (group C). Regarding mean pH value, there was a significant difference between the 3 groups with an obvious reduction in pH values of groups B & C. Moreover, the findings showed that the means of salivary total proteins and salivary alpha amylase were significantly higher in group B than in group A and group C. Conclusion: According to ROC curve analysis salivary total proteins reflect an excellent predictor test where the value of total salivary proteins above 8.381 g/dl indicated ALL leukemia with 100% accuracy in children.

Objective: To establish McNamara Cephalometric Analysis normative data for Egyptian children. Materials and Methods: Twenty boys and forty girls (mean age 9.37, SD 1.60) of Egyptian ethnicity were selected based on the following criteria: Class I molar relationship, lack of crossbite or scissor-bite, adequate amount of space in dental arches, no visible asymmetry, and good facial proportions. Eleven selected variables from McNamara’s cephalometric method were digitally traced and analyzed on the lateral cephalograms of each subject. Results: McNamara’s skeletal and dental variables were assessed and statistically significant inter-gender differences were noted in both effective midface length (condylion to point A) and effective mandibular length (condylion to gnathion). Conclusions: Young Egyptian boys had a lengthier midface and mandible than girls. The Upper incisors to point A vertical and lower incisor to A-PO line were slightly more pronounced in girls.

Purpose: To estimate the effect of prolonged continuous force on the shear bond strength (SBS) of orthodontic brackets bonded with different adhesive systems. Materials and Methods: Eighty premolars were randomly divided into four groups (I, II, III and IV) according to the bonding adhesive used. Orthodontic metal brackets were bonded with one of the succeeding adhesives; Rely-a-bond, Transbond XT primer and adhesive, Transbond Plus self-etch primer (SEP) and Transbond XT adhesive and Smart Bond. Half of the brackets were subjected to 150 g of force for 12 months. All the specimens were thermocycled 1000 times between 5° C and 55° C. A Universal Testing Machine was used to measure SBS. Results: Transbond XT primer and adhesive exhibited the highest significant SBS value (12.8Mpa). Smart bond showed the lowest value (7.7Mpa). Rely-a-bond and Transbond Plus SEP adhesive systems had middle values (8.8 and 7.8Mpa). There was a significant decrease in the SBS of all studied adhesives (P<0.05) accompanied force application (P <0.05). Smart Bond showed the higher reduction in SBS while Transbond XT primer + Transbond XT adhesive revealed the lesser reduction. Conclusion: Application of 150 gram of force for 12 months produced a pronounced negative effect on SBS especially with either SEP or Smart Bond.

DENTOSKELETAL PARAMETERS IN INDIVIDUALS WITH MAXILLARY CANINE DISPLACEMENT (A RETROSPECTIVE STUDY)
Waleed
Refaat
No studies have been done to measure the skeletal, dentoalveolar and soft tissue parameters in subjects with palatally and buccally displaced canines. The hypothesis of this study is that there is difference in the skeletal and dentoalveolar measurements between subjects with palatally, buccally and normally erupting canines. A total of 200 subjects with maxillary canine displacement (90 palatally displaced, 110 buccally displaced) were recruited for this study. The age of the subjects ranged between 13-15 years old. Subjects were divided into 2 groups (maxillary palatal canine displacement and maxillary buccal canine displacement). These subjects were compared with 100 subjects asa control group. In conclusion,There in is no significant difference in maxillary length between subjects with buccally and palatally displaced canine and control group. However palatal canine displacement group had reduced vertical dimensions, increased overbite, small dentoalveolar heights and retruded upper and lower lips.

Purpose: To evaluate the effect of anodization surface treatment on the stability of minimplants ( MIs ) during en-masse retraction. Materials and Methods: The sample of this split mouth; clinical trial, consisted of 27 patients with an allocation ratio of 1:1. Forty five MIs (1.8 mm diameter and 8 mm length) were divided into: 27 MIs with surface treatment by anodization technique while the other 27 were with smooth surface (group B). Finishing, leveling and alignment, the surface treated MIs and the smooth ones were randomly inserted between the roots of maxillary 2nd bicuspid and 1st molar at the mucogingival junction on both sides of each patient. After two weeks healing period, bilateral extraction of maxillary 1st bicuspids were done. Closed coil spring was extended from the MI head to along hock secured onto the main arch wire between the maxillary lateral incisor and canine on both sides, delivering 200 g force per side to en-masse retract the upper anterior teeth. The average observation period lasted 9–12 months. Results: In total, 40 of 54 minimplants were able to achieve the treatment goals. In group A, 22 (81.5%) mini-screw implants presented long-term stability, while in group B, only 18 (66%) minimplants were stable throughout the treatment. This difference was statistically significant (P =.0311). The total success rate for all inserted miniscrew implants was 74%. Conclusion: Anodized surface treated orthodontic mini-screw implants are more stable than smooth surface one during en-mass retraction.

Aim: We aimed to evaluate the attitude of senior dental students towards clinical education in paediatric dentistry. Methods: This was a cross-sectional, descriptive study performed on dental students during their final (senior) year at King Saud University, Saudi Arabia. A structured questionnaire was used to collect data in two parts, i.e., demographic information of the participants (age and gender) and sixteen questions about the students’ educational satisfaction towards the clinical education of pediatric dentistry. Data were analysed using the chi-square test with p-values Results: A total of 109 dental students were enrolled (56% were male and 44% were female). There was a significant difference in the clinical education satisfaction level between male and female. Majority of the student had a sufficient knowledge about clinical procedures. However, only 41% and 45.9% students had a positive attitude towards education on drug prescription and pulp therapy of young permanent teeth, respectively. Conclusion: The results of this study showed that senior dental students were satisfied with most of their clinical education received in paediatric courses, but there was a lack of knowledge on drug prescription and pulp therapy in young permanent teeth.

Despite the fact that 3D volume is versatile, the current 3D analyses are still saturated with a 2D spirit. We aim at presenting a new three-dimensional measurement for skeletal classification. A sample of 30 subjects having normal occlusion and balanced facial proportions and 30 patients with skeletal component of malocclusion were scanned using CBCT. A new measurement was tested to determine the skeletal classification. Results showed that the new measurements proved sensitive in delineating the different skeletal classes

Back to nature is the concept that most of workers in the medical and dental fields are searching for nowadays. Coconut oil and Nigella sativa are used to treat a wide range of health problems. In the dental field they had been documented to possess an inhibitory effect on some oral cariogenic microorganisms. Aim: Thus, the aim of the current study was to evaluate the antibacterial effect of Coconut and Nigella Sativa oils on Streptococcus mutans, Lactobacilli and Candida albicans as a natural mean for prophylaxis against dental caries. Materials and methods: Two herbal oils (Coconut and Nigella sativa) and Chlorhexidine gluconate 0.2% as a positive control were used in this study. Streptococcus mutans, Lactobacilli, and Candida albicans were isolated and incubated. Growth inhibitory effect of the tested materials was evaluated by direct contact method for each microorganism separately by adding 0.5 ml. of the tested material to each organism in a sterile tube and incubated at 37°C aerobically for Streptococcus mutans and Candida albicans and anaerobically for Lactobacilli then the tested microorganisms were spread on specific media. The count of the microorganisms was expressed as CFU/plate and recorded after 2 and 24 hours. Results: Coconut oil showed marked % of reduction on both SM and Candida albiacans (89.3 % and 87.3 %) after 24 hours contact period. Nigella Sativa oil showed marked reduction on SM after 2 hours only (68.33%) with no effect on Candida albicans. Both oils had no effect on LB. The highest % of reduction of all tested microorganisms was recorded with Chlorhexidine. Conclusions: Coconut oil has a great inhibitory effect on both SM and Candida albicans with this effect extending by time, but no effect on LB. Nigella sativa oil has an inhibitory effect on SM over a short contact period, but this effect decreased and even vanished by time, but it has no effect on neither Candida albicans nor LB. Chlorhexidine showed the most superior results on all tested microorganisms.

Aim: to reveal relation between clinical and radiographic evidence of failure following pulp therapy in primary teeth among patients less than six years old. Subjects and Methods: The study was carried out on 100 mandibular primary molars treated by formocresol pulpotomy and 50 maxillary primary anterior teeth treated by pulpectomy in patients showing radiographic evidence of failure, regardless of their clinical conditions. Clinical examination was performed and clinical failures were given scores as follows; score 0: normal, score 1: history of pain, score 2: gingival swelling/sinus tract, score 3: purulent exudate and score 4: excessive mobility. Radiographic examination was accomplished to detect any signs of failure. Radiographic failures were given scores as follows; score 1: internal or external resorption, score 2: periapical radiolucency, score 3: widening of periodontal membrane space and score 4: furcation infection. Results: Significant difference was noted (P=0.001) when type of teeth and radiographic scores were compared. Relation between clinical scores and type of teeth was statistically insignificant (P=0.295). Significant difference was noted (P =0.001) when type of treatment and radiographic scores were compared. No significant difference was revealed comparing type of treatment and clinical scores (P=0.900). Statistical analysis revealed no statistical significant difference relating radiographic and clinical scores (P= 0.410).Conclusion: Evidence of radiographic failure was revealed in clinically successful treated primary teeth. Thereby, radiographic examination is not elective in determining success/failure of treatment.

Amr
Abdel Latif
Aim: to assess the changes taking place in D E space caused by untreated interproximal caries of primary molars during the mixed dentition. Subjects and methods: This study was a cross-sectional one. A sample of 52 children between 7 to 9 years of age with unilateral interproximal caries of first and/or second primary mandibular molars was assessed to detect the change in D E space caused by loss of contacts due to interproximal caries. D E space change was defined as the change in the distance between the midpoint on the mesial surface of the mandibular permanent first molar and the midpoint on the distal surface of the mandibular primary canine (DE Space). The space change between damaged sides and the intact control sides was measured by cast analysis using digital caliper. Interexaminer reliability was high (0.970). Results: The results showed the measured change of D E space on the damaged sides was significantly reduced when compared to the control sides (P< 0.001). Conclusion: The study concluded that the space needed for eruption of permanent teeth decrease significantly after loss of proximal contacts of primary molars due to interproximal caries in mixed dentition stage.
