Purpose: This study aimed to evaluate the effect of using full thickness mucoperiosteal flap (FTMPF) elevation only versus low level laser therapy (LLLT) on acceleration of orthodontic tooth movement. Material and Methods: This study was a split mouth design study included 32 side according to sample size calculation. Those sides were divided into 2 groups. Group 1divided into (group 1a: 8 sides with FTMPF, group 1b:8 sides control). Group 2 (group 2 a: 8 sides with LLLT, group 2b: 8 sides control). Extraction of the first maxillary premolars followed by canine retraction in the extraction space with maximum anchorage were indicated. FTMPF was elevated from the mesial interdental papilla of maxillary canine to the mesial interdental papilla of second maxillary premolar. LLLT was applied at the 3,7,14,28.56 days of retraction. During retraction study model for all patients were taken at 2nd, 6th, 14th,16th weeks and at the end of retraction (I1,I2,I3,I4,I5 or overall interval). 3D laser scanning and digital superimposition was done to measure the rate of canine retraction and anchorage loss. Results: Statistical analysis showed a significant difference in the distance moved by maxillary canine and weekly rate of retraction between the FTMPF and its control in I1, I2 and I5 and in I2, I3 and I5 LLLT and its control. The total retraction time was significantly decreased in both FTMPF and LLLT in comparison to control. Conclusions: FTMPF could accelerate orthodontic tooth movement with 25%, while LLLT could achieve 20% decrease with no significant difference between both techniques.

Purpose: To assess the electromyographic activity of oral muscles concomitant to Class II malocclusion correction using Carrier Distalizer appliance. Materials and Methods: 10 female patients with age ranged between (18-21) years old were selected for this study. All patients were examined to fulfill the inclusion criteria. All patients in this study underwent radiographic evaluation (panoramic and lateral cephalometric) and electromyographic evaluation before and after Class II correction using Carrier Distalizer appliance. Study duration for patients was six months. Results: The result of this study showed that no significant changes occurred in skeletal measurements except increase angle of convexity. Regarding electromyographic measurements there is statistically significant increase in masseter muscle activity at rest and at occlusion after treatment. And about the dentoalveolar changes including slight maxillary molar distalization, in addition to mesialization of the lower molars and proclination of the lower incisors. Conclusion: It was concluded that Carrière Distalizer appliance was able to correct Class II molar relation into Class I relation in adult patients with masseter and temporalis muscles activity were improved after treatment.

Purpose: to evaluate the effect of low level laser on leveling and alignment by using two types of orthodontic archwires. Materials and methods: A consecutive sample of 32 patients requiring fixed orthodontic appliances were grouped into four groups: laser group with 0.014 inch copper NiTi wire, laser group with 0.014 inch superelastic NiTi wire, 0.014 inch copper NiTi wire group without laser, 0.014 inch superelastic NiTi wire group without laser. Directly after the first arch wire insertion the investment group received a LLLT dose (laser application group of patients). The LLLT device was adjusted to 635 nm wavelength and with 2.2 J/point (energy dosage). There were four points of application regarding each mandibular incisor’s root, two of them are buccal and the other two points are palatal. This laser dosage was applied repeatedly on 7, 14 and 28 days for each patient in the laser group. The evaluation of alignment by studying four casts taken along the initial stage of treatment (before treatment T0, Two weeks T1, four weeks T2 and six weeks T3 of treatment). Results: Statistical analysis between the groups revealed that there was no statistically significant difference between the four groups at four different intervals (T0-T1), (T1-T1), (T2-T3) and (T0-T3) (P-value = 0.813, 0.601, 0.646, 0.340) respectively. Conclusion: The two forms of NiTi wires (superelastic NiTi wire and Cu NiTi wire) during the alignment process in the initial stage of the treatment were the same regarding the efficiency of alignment, either with or without laser application, and for the acceleration of the tooth movement in orthodontics the application of LLLT wasn’t effective during the initial aligning stage of orthodontic treatment either with superelasti NiTi wire or Cu NiTi wire.

Purpose: This study was conducted to evaluate the effect of Thyme extract mouth rinse against Chlorhexidine mouthwash on salivary Streptococcus mutans count in a group of Egyptian children. Materials and Methods: A total of 70 Egyptian children were included in this study. Children ages ranged from 5 to 10 years old in a good physical condition. Children were randomly distributed into two groups A & B each of 35 children. In children of group A (using Thyme extract) each participant was instructed to rinse with 10ml of thyme extract for one minute. In group B (control group using Chlorhexidine mouthwash 0.2%) each participant was instructed to rinse with 10ml of CHX for one minute. Results: There was a significant reduction in Streptococcus mutans count in both groups. Conclusion: Thyme extract mouthwash was successful as an antimicrobial agent. It significantly reduced the total bacterial count in the saliva of children when compared to a potent antiseptic like Chlorhexidine.

Purpose: compare the chemo-mechanical method of caries removal (CMCR) using Carie-Care™ and conventional technique (Drilling) in normal and disabled Egyptian children. Materials and Method: A total of 40 children were divided into two equal groups .Group A: 20 healthy and normal children. Group B: 20 children with different types of disabilities, either intellectual disability, hearing impairment or visual impairment. Their age ranged from 5-8 years .Two primary carious teeth were chosen in each child according to inclusion criteria (total 80 teeth). The eighty primary teeth from forty children were further subdivided equally into two subgroups (40 teeth in each subgroup) according to caries removal technique. Subgroup Ӏ: caries was removed with CMCR using the Carie-Care system. Subgroup ӀӀ: caries was removed with the conventional drilling technique. Then all teeth were restored with Activa kids bioactive restorative material and followed up at baseline, one month, three months and six months intervals. Results: Results of this study showed that there was no significant difference between patients’ groups regarding complete caries removal, total time taken for complete caries removal, pain and patient comfort, but there was a statistically significant difference between both techniques regarding complete caries removal in disabled children group (Group B), and a significant difference was also found in the time taken for complete caries removal , pain and patient comfort in both patients’ groups. Also, there was no statistically significant difference between patients’ groups regarding the longevity of Activa kids bio-active restorative material at base line, one month, three months and six months follow up periods. Conclusion: Carie‑Care™ gel was an efficacious alternative method to treat carious lesions in both normal and children with different disabilities since it allies atraumatic characteristics. Activa kids bioactive restorative material had an excellent performance as a permanent restorative material in vital primary teeth in both normal and disabled children in a period of 6 months.
