In addition, the heredity role in hypodontia was investigated. Materials and Methods: About 3415 subjects, 1750 females and 1665 males aging between 18–30 years were examined clinically in addition periapical radiographs were taken for each patient to exclude a possibility of impaction. A family history of hypodontia for each patient was taken (for father, mother, brothers and sisters). Then the sample was divided into 3 groups depending on Angle’s classification of malocclusion. Results: No clear association was found between Angle's classes and hypodontia, females showed higher prevalence of hypodontia than males. Family history was obvious in patients with hypodontia. The upper lateral incisor was the most frequent absent tooth. Conclusions: No association was found between Angle’s classification and hypodontia. The upper lateral incisor was the most frequent missing tooth. Maxilla was affected by hypodontia more than mandible.

Materials and Methods: In general, the number of acrylic resin samples that had been used in this study was 20 samples. Curcumine solution had been dissolved in three different solvents, those were ethanol, viscous (glycerine), and sterile distilled water, while cholrhexidine (CHX) alone used as a control negative and distilled water used as a control positive. The diameter of inhibition zone for the different curcumine solution had been measured and compared with control (–ve, and +ve); the biofilm activity of Candida albicans on A.R.D.B.M. was measured by a new method using pH change of stomastat. Results: Demonstrated that the ability of curcumine solution to decrease fungal biofilm activity on A.R.D.B.M varied depending upon the type of solvent in which the solution had been dissolved, and ethanolic solution (50%) was the most effective in reducing biofilm activity of C. albicans on A.R.D.B.M. when compared with CHX solution which is the most commercially used solution as denture cleanser.

Results: The results of this study revealed that the chemotherapeutic agents modify oral health and there was significant increase of plaque and gingival indices in children receiving chemotherapeutic agents (at p≤0.05), also results showed that there was a significant reduction after rinsing with chlor-hexidine digluconate for plaque and gingival indices (at p≤0.05), while non significant change for salty water mouth wash. Conclusion: In view of the possible factors that causes increase of the plaque and gingival indices, suggested myelosuppresion that is associated with chemotherapy which has effects on rate and pattern of hard and soft tissues resulting in reduced the ability to repair and maintain the oral health status.}, keywords = {Chemotherapy,Oral Health,chlorhexidine mouth wash}, title_ar = {الحالة الصحیة عن طریق الفم بین الأطفال الذین یتلقون العلاج الکیمیائی}, abstract_ar = {}, keywords_ar = {}, url = {https://rden.mosuljournals.com/article_40056.html}, eprint = {https://rden.mosuljournals.com/article_40056_ed5289d3d2c206781399e37db5fc2958.pdf} } @article { author = {Ahmad, Zeina and Jawad, Inas and Al–Ali, Ahmed}, title = {Clinical determination of the occlusal plane and its relation with orofacial measurements}, journal = {Al-Rafidain Dental Journal}, volume = {7}, number = {1}, pages = {101-110}, year = {2007}, publisher = {University of Mosul}, issn = {1812-1217}, eissn = {1998-0345}, doi = {10.33899/rden.2007.40057}, abstract = {Aims: To determine the level and angulation of the occlusal plane of the artificial dental arch by measuring the level and angulation of the occlusal plane of completely dentulous subjects and to find the relation of these measurements to some of the vertical facial and intra oral dimensions. Materials and Methods: The sample of the study consisted from 54 completely dentulous adult subjects (24 female and 30 male) with class 1 normal occlusion aged 19–24 years. Dental casts were taken for each subject, the level and angulation of the occlusal plane, vertical facial, and intra oral dimensions were measured using digital vernier caliper and protractor. The data were analyzed with statistical package for social science program. Results: Sexual differences were found in the intra and extraoral measurements. Most of the measurements dealing with the occlusal plane level and angulation were correlated with each other and with facial measurements. Conclusions: The level and angulation of the occlusal plane of the maxillary and mandibular dental arches as measured on the dental casts are higher in maxilla than in mandible and the intra and extraoral vertical facial measurements are greater in male than female.}, keywords = {Occlusal plane,facial measurements,Vestibular distance}, title_ar = {التحدید السریری لمستوى الاطباق وعلاقته لقیاسات الوجه والفم}, abstract_ar = {}, keywords_ar = {}, url = {https://rden.mosuljournals.com/article_40057.html}, eprint = {https://rden.mosuljournals.com/article_40057_984cb6156d8d6e6571a3f9e3502f07ba.pdf} } @article { author = {Al–Ali, Ahmed}, title = {Evaluation of macrohardness of recasted Cobalt–chromium alloy}, journal = {Al-Rafidain Dental Journal}, volume = {7}, number = {1}, pages = {111-117}, year = {2006}, publisher = {University of Mosul}, issn = {1812-1217}, eissn = {1998-0345}, doi = {10.33899/rden.2006.40062}, abstract = {Aims: To study the effect of recasting on the macrohardness of cobalt chromium (Co–Cr)alloy, and to evaluate the effect of finishing and polishing on it. Materials and methods: Two brand of Co–Cr alloys were used, divided into three groups, the specimens of the first group were casted from new materials, the second were casted from previously casted material without the addition of any new material (100% recast), the third were casted by combination 50% new material and 50% used material. Half of the specimens just finished and the other half were finished and polished , hardness for all of them were measured. Results: Showed that recasting, both 100% and 50%, significantly increase the macrohardness of Co–Cr alloys and no significant effect of finishing and polishing on it. Conclusion: Recasting may affect properties of Co–Cr alloy and new material should be used rather than recasted material.}, keywords = {Recasting,Macrohardness,cobalt,Polishing}, title_ar = {تقییم الصلابة الکلیة لسبائک الکوبالت والکروم المعاد صیاغته}, abstract_ar = {}, keywords_ar = {}, url = {https://rden.mosuljournals.com/article_40062.html}, eprint = {https://rden.mosuljournals.com/article_40062_c52a7580ba48758b7f1b7827b389980d.pdf} }
