It is a retrospective study of peripheral cemento-ossifying fibroma for patients of the faculty of dentistry – Damascus university, and a histological comparative study of the collageneous and mineralized constituents between the lesions of the maxilla and mandible.

the fibroma's correlation with age, gender and the location of lesion, and then to conduct an analytical study of the collagenous and mineralized constituents between the lesions of the maxilla and mandible for the patients of the faculty of dentistr
y, Damascus university.
Methods & Materials: Our study covered 36 patients aged 9 – 40 years, (average 24.5 years old), 12 males and 24 females. Central cemento-ossifying fibroma was diagnosed and treated at maxillofacial surgery department, the oral histology and oral pathology department, faculty of dentistry, Damascus university,
between 2004 and 2008. Biopsies were studied after they had been stained with hematoxylin and eosin.
The analytical tables were made using SPSS program, issue 13.0 and Chi square test for Sig<0.05.
Results: The clinical examination of the tumor showed hard swelling covered by normal mucosa. The
proportion of tumors in females was 2:1 for males in the third decade of life. 58.3 of lesion were in the
mandible mainly in premolars and molars. The histological study showed fibrous connective stroma of bundles of collagenous fibers including fibroblasts and mineralized materials either osseous, osteoid or cementoid. Bundles of collagenous fibers formed 55.6% of fibrous connective. The ratio of laminar bone
trabeculae was varied between 40% for the maxilla and 67% for the mandible. Osteoid material existed by 60% in the maxilla and 33% in the mandible. 90.5% of mandibular tumor compared with 73% of that of the maxilla were surrounded by a true complete connective capsule. The statistics study showed a
correlation between the mineralized materials and the location of lesion Sig<0.05.
Conclusion: central cemento-ossifying Fibroma appeared much greatly in females of thirties and it trended to defeat the mandible more than the maxilla. There was an important correlation between the mineralized materials and the location of lesion.
This retrospective study is to correlate oral squamous cell carcinoma with age,
gender and location of lesion, and to investigate the correlation between the grade of the malignancy and
lymph nodes in patients of the faculty of dentistry, Damascus university.
To evaluate the technical quality of root canal treatment performed by
undergraduate students and to detect iatrogenic errors.
Objective: to assess the clinicopathologic features of tumors of the hair
follicles.
This study included 35 patients with tumors of the
hair follicles seen at dermatology and venereology hospital at Damascus
university during 2 years (2007-2008). A retrospective study of patient's files
and re-examination of their histological slides were done.
This study aims to assess the feelings of children toward dental treatment in the
department of pediatric dentistry in order to point the reason of dental fear. The sample
includes 385 children (191 males, 194 females, aged 4-12 years) come to facu
lty of
dentistry between 1/10/2015 – 1/6/2016. The questionnaire form was adapted. Data were
analyzed using statistical program SPSS.
SMA was: fear = 2.96 , anxiety = 2.82 , trouble = 2.74 , like (desire, preference) =
3.56 , feelingsafter treatment = 3.37 , discomfort of the transaction = 1.82 , desire to repeat
the visit = 3.97. The result showed most of the children were not afraid, not worried, not
upset, and they like to repeat. While 9.9% trouble and 6.5% don't like to repeat it. We
concluded that the dental services in p.d department are effective and acceptable.
