Title: Effect of Co2 laser (10.6 µm) and Remin Pro on remineralization of enamel white spot lesions
Biography:

Pooya Fadaei has completed his DDS at the age of 25 years from Yazd University of Medical science.Iran. He has published 1 paper in reputed journals and has another paper for submission.

Abstract:

Background and Aims: This study investigated the combined effect of Co2 laser irradiation and Remin Pro paste on treatment of enamel white spot lesions (WSLs).
Materials and Methods: Seventy-eight intact premolars were randomly assigned into six groups and then stored in a demineralizing solution to create WSLs. Afterwards the teeth in group 6 (negative control) remained untreated while groups 1 and 4 were exposed to Co2 laser irradiation (20 Hz, 1W, 30 seconds) and Remin Pro paste, respectively. In groups 2 and 3 teeth were exposed to laser either before (group 2) or after (group 3) Remin Pro application. Teeth in groups 1 to 5 were then immersed in artificial saliva for 90 days while subjected to fluoride mouthwash and weekly brushing. Finally, teeth were sectioned and Vickers microhardness was measured at the enamel surface and at 50,100 and 150μm from the surface. One sample of each group was also examined with scanning electron microscope (SEM). Data were analyzed by two-ways Analysis of variance (ANOVA) and Tukey test. The significance was set at 0.05.
Results: Laser irradiation followed by Remin Pro application (group 2) caused a significant increase in total WSLs’ microhardness compared to laser alone (group 1) and control groups (p<0.05). Microhardness at depths of 100 and 150 μm was also significantly greater in group 2 compared to those of group 3 and control groups (p<0.05).
Conclusion: Combined application of Co2 laser with Remin Pro paste, when laser is irradiated before the paste, is suggested for rehardening of WSLs.

Abstract:

The purpose of this study was to assess the effect of free-flap reconstruction of patients with advanced stage IV oral squamous cell carcinoma following ablative tumor resection. The purpose of this study is to elucidate the reconstructive indications of the use of simultaneous double free flaps in head and neck oncological surgery.
Method
The study was based on a restrospective cohort of 76 patients with pathological stage IV OSCC patients (without distant metastasis) treated by tumor ablation with free flap reconstruction. Of the 76 patients, 49 (Group 1, Test) underwent surgical reconstruction with microvascular tissue transfer and in 27 (Group 2, Control) only local or regional flaps were used. Fibula osteo-cutaneous free flap was used in association with forearm free flap in 18 cases, fibula osseous-forearm in 7 cases, fibula osseous-rectus abdominis in 1 case, iliac crest-forearm in 1 case. Forearm free flap was used for intra-oral reconstruction in all cases. We compared patient survival and cancer recurrence rates between these two groups.
Result
Despite the unfavorably expected prognosis in group 1, both positive margin rate (12.2% in Group 1 versus 21.5% in Group 2, P = 0.112) and cancer recurrence rate (26.6% in Group 1 versus 28.3% in Group 2; P = 0.671) were not significantly different between the two groups. At the end of the follow-up period, 23 (47%) and 33 (67.3%) patients had died of oral squamous cell carcinoma in the microvascular reconstructive and control group, respectively. In the free-flap group, the mean and median survival time was 54 months. In the locoregional flap group, the mean and median survival time was 51 months respectively. No difference was seen in the survival time between the free-flap and local flap groups (P = .2). Univariate Kaplan-Meier analysis revealed that positive surgical margins were significantly associated with shortened survival in the free-flap group and that recurrence was significant in both reconstructive groups. On multivariate Cox regression analysis, the status of the resection margin (P = .05) and tumor recurrence (P < .0004) showed a significant relationship with survival.
Conclusion
Patients with free-flap reconstruction of surgically created defects after oral cancer resection showed a trend toward better 5-year survival. Simultaneous free flap reconstruction, in massive oro-mandibular defects, represents in some selected patients, a good choice to achieve satisfactory aesthetic and functional results.
 

Dina Osman ElAbbasy

Cairo University, Egypt

Title: Palatally erupted maxillary lateral incisors may be a causative factor of mandibular deficiency
Biography:

Dr Dina graduated from Faculty of Dentistry Cairo University in 2002 with high honors and 2nd ranking. She completed her residency and then enrolled in the department of Orthodontics as a resident for 3 years during which she completed her Master Degree. She then registered for her PhD and was awarded the degree in 2013. She has extensively lectured students at the dental school and has attended several local and international conferences/lectures.

Abstract:

The aim of this study was to evaluate the influence of palatally displaced maxillary incisors on mandibular growth in a group of Egyptian patients. 
 
Material and Methods: The sample consisted of the digital lateral cephalograms of  24 patients with age range of 15-30 years during the permanent dentition stage. The radiographs were selected from the patient database of private practice in Cairo. The sample was divided into 2 groups each consisting of 12 patients. Group A had palatally displaced maxillary lateral incisors without crossbite. Group B had palatally displaced maxillary lateral incisors with crossbite. Cephalometric measurements were used to assess the anteroposterior skeletal malocclusion (SNA, SNB, ANB, Witts appraisal). Independent samples t-test was performed between two groups. 
 
Results: Cephalometric measurements revealed statistically significant differences between groups A and B. Group A had skeletal Class II with retrognathic mandible while group B had skeletal Class I pattern with normal mandibular position. The maxilla was well positioned in relation to the cranial base. No statistically significant difference between genders was evident. 
 
 
Conclusion: Palatally displaced maxillary lateral incisors without crossbite cause restraining effect on normal mandibular growth which results in skeletal Class II with mandibular deficiency.

Abstract:

In humans facial assymtery is very common. But when this asymmetry is present in significant amount it causes both functional as well esthetic problems. Among all asymmteries encountered midline discrepancies are commonly seen and most complex problems in clinical practice. If ideal correction is to be achieved, all the three of the patient’s midline  facial , maxillary and mandibular should be co incident. Skeletal , soft tissue , and dentoalveolar assymtery may be present alone or in combination in a ptient presenting with non co incident midlines. Due to multifactorial etiolog of midline discrepancies , a thorough understanding of components that may contribute to the problem is essential for correct diagnosis and treatment planning.
