Abstract: The aim of this study was to examine the evidence behind the use of the composite of bone marrow concentrate and Nano-hydroxyapatite as an alternative to autologous bone graft in the repair of bony defects. The study was conducted on 14 residual surgical non-continuity defects resulting from enucleation of benign odontogenic cysts. The defects were randomly allocated into two groups according to defect filling as follows: Group A (n=7), the defects were grafted using a composite of bone marrow concentrate (BMC) and Nano-hydroxyapatite granules; Group B (n=7), the defects were grafted using autologous bone graft. Radiographic evaluation was done using Cone beam C. T. scan, immediate, six and twelve months post-operatively to assess the volumetric changes of the grafts along the follow-up period. The results of this study revealed that there was no statistically significant difference (p>0.05) between the two groups regarding the percentage of reduction of the graft volume along the follow-up period. In the light of the radiographic results of this study it can be concluded that the use of composite of bone marrow concentrate (BMC) and Nano-hydroxyapatite granules to reconstruct surgical defects is a reliable alternative to autogenous bone graft.

Abstract: Medical ethics principles are universally accepted. However, each country can make some modifications and develop specific clarifications reliable with countries’ existing culture. As with any profession, dentists have a responsibility to their patients and communities in which they practice, more over it is essential that dental professionals understand and practice honestly the code of ethics which is approved by the ministry of health in Iraq. Researcher aim is to highlighting the importance of ethics in general and dentistry as specific; understand the different echelons in knowledge between professional's dentists and to identify dental intern level of understanding the ethics responsibilities were given in the questionnaire. A cross-sectional questionnaire study was accomplished among three groups of dentist in Nineveh. The sample size of 240 participants was calculated from the total number of dentists (979) in Nineveh allocated between intern resident, general practitioners and dental specialist. For data collection we use a revised specialized questionnaires published by Satish Deo and his colleagues in 2018. A self-administered, 40 - itemed questioner encompassing four sections: general information, knowledge, attitude, and practice of ethics in dental healthcare were employed. Data are statistically analyzed shows that most dentists' age is ranged between two levels (less than 28 y and from 36 to 43y) with mean age (36.66 years). In spite of that females are forming the high percentage (63.8) in practitioners group but no sex predilection in the total result. Specialist show high significant scores in the statistical analysis when compared with practitioners and interns. The last group shows the least level in knowledge. Concluding from this study that reputation to be part of medical healthcare persons make dentist forced to follow the ethical roles in the country where he live and should be an ideal example for others in the society as we are the mirrors of each other's.

Abstract: Objective: To compare the effects of filling bone gap between implants with bone graft materials of different sizes and forms of primary stability after alveolar split osteotomy process. Materials and Methods: Materials and Methods: Fourty fresh ribs were divided into four main groups. The groups created are based on the xenograft material of different sizes and forms; group Putty (P): Group applied Putty (form) graft (granule size 0.25– 1 mm), group Small (S): Group applied Small particle graft (granule size 0.25– 1 mm) group, group Large (L): Group applied Large particle graft (granule size 1– 2 mm), control group (C): classified as group where no bone graft was applied. Bone expansion was performed using piezosurgery. In all groups, two implants were inserted into the each rib after alveolar crest expansions. The gap between implants (outside the control group) was filled with bone graft materials of different forms and sizes (large, small, putty). The primary stability values of the implants were measured with in the direction of the bucco-lingual (BL) and mesio-distal (MD) by the ISQ (implant stability quotient) and compared between groups. Results: The primary stability values measured in the BL direction are higher than the primary stability values measured in the MD direction and values are statistically significant difference. There is no statistically significant difference between the 1st and 2nd implants in each group (C, P, S, L) for their measured values in both BL direction and MD direction. Conclusion: According to the ISQ values used to evaluate primary stability, it was found that the graft materials of different sizes used in our study did not cause a significant difference for the primary stability of the implants.

Abstract: The central giant cell granuloma (CGCG) of the jaws is a rare benign tumour of the mandible (lower jaw) and the maxilla (upper jaw) characterized by destruction of the bone, loss of symmetry of the face and displacement of teeth and tooth germs, especially in younger patients. It is asymptomatic and present with slow growth often accompanied by dental mobility. The removal of this tumour is mutilating and is followed prosthetic rehabilitation. The aim of this study was to report a case of central giant cell granuloma localizated to the symphyseal region in a young patient. The case reported is that of a 14-year-old girl who received a consultation for a tumor in the symphysical region causing an aesthetic impact. The tumor was firm, painless and had been developing for about a year. The cortical were broken in places, in transverse, sagittal and coronal sections. The treatment consisted of her excision under general anesthesia causing a significant loss of substance. The tumor mass, very hemorrhagic, was extended to the buccal floor. At the end of the intervention, a significant loss of substance was observed. Two months later, a partial adjunct prosthesis was performed. The anatomo-pathological examination showed of several multinucleated giant cells, a few histiocytes, lymphocytes and fibroblasts. The removal of this aggressive tumour remains mutilating, with significant psychological repercussions. More recently, antiangiogenic therapy with interferon alpha has been successfully applied.

Abstract: The purpose of this study was to evaluate the dentin bond strength of restorations made of different polymeric materials with Single Bond Universal Adhensive and etch-and-bond resin cement. Ceromer (ceramage, Shofu), Polymethylmethacrylate (PMMA DISK, Yamahachi), resin nanoceramic (Lava Ultimate, 3M ESPE), and polymer-infiltrated-ceramic-network (Vita Enamic, Vita Zahnfabrik) specimens (n=15/group) were fabricated respectively. Dentin specimens were prepared from extracted third molars stored in distilled water in a refrigerator (4°C). Single Bond Universal Adhensive was applied to the prepared tooth and light cured. Then, specimens were cemented using 3M ESPE RelyXTM Uitimate ClikerTM adhesive resin cement. All cemented specimens were stored in distilled water for 24 h and subjected to shear forces by a universal testing machine. Vita Enamic was found to show the highest shear bond strength values. The shear bond strength of Lava Ultimate was weaker than that of Vita Enamic. But there was no statistical difference between Vita Enamic and Lava Ultimate. Both of them showed significantly higher shear bond strength than the Ceramage and PMMA groups. The lowest values were obtained for PMMA and there was a significant difference between the PMMA and Ceramage groups. The bond strength of the polymeric materials is material dependent. So doctors can use them for patients with different intent.

Abstract: Introduction: A tooth that is unable to erupt completely due to some physiological barrier is called impaction. The extraction of the impacted mandibular 3rd molar is the most frequent procedure in oral surgery. The removal of 3rd molar is associated with complications like damage to the inferior alveolar nerve which causes paresthesia of the lower lip depending upon the severity of the damage. Objectives: This study assesses the diagnostic efficacy of orthopantomograph in predicting the association between mandibular third molar roots and inferior alveolar canal and its juxtaposition with intra-operative surgical findings. Material and methods: This cross-sectional research was conducted in the department of Oral & Maxillofacial Surgery, King Edward Medical University/Mayo Hospital, Lahore, requiring extraction of mandibular third molars surgically. Patients underwent extraction under local anesthesia. The association between M3 and IAC by comparing OPG findings with intra-operative surgical findings was assessed by chi-square analysis. Results: One hundred and twenty patients requiring mandibular third molar extraction were included in the study. The age of the patients involved in the study ranged from 21-70 years. There were 5 cases of nerve injury in the age group of 31-40 and 1 case in each age group of 21-30 and 41-50. Conclusion: The chances of nerve damage also increase significantly when there is more than one radiographic sign present and the tooth is deeply placed in the mandible nearest to the IAN.
