إن استعمال مواد مبطنة أكريلية قاسية ذاتية التماثر خالية من الميثيل ميثاكريلات يقدم ميزات إيجابية كثيرة، لكن تأثير هذه المواد في المخاطية الداعمة للجهاز غير مدروس. الهدف من البحث: هدف بحثنا إلى دراسة التغيرات السريرية و النسيجية التي تطرأ على المخاطية الداعمة للجهاز عند تطبيق إحدى مواد التبطين القاسي المباشر.
The use of acrylic chairside hard denture lining materials introduces a lot of benefits; but the effect of these materials on the oral mucosa was not studied. The purpose of the research: This investigation was undertaken to determine the clinical and histological changes in the residual alveolar ridge mucosa when an acrylic chairside hard denture lining material was used.

Khat chewing is a deep-rooted habit in Yemen. It has many
negative impacts on different body systems. The spread of khat chewing
among adult males in Yemeni society needs special attention. Cathinone
and cathine are the most stimulants of khat ing
redients. Other ingredients
could have other implication such as gastrointestinal carcinogenic tannins.
the aim of this study is to Investigate chronic khatchewing
effects on oral mucosa and the role of concurrent smoking.
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.
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 objective of this study was to know the influence of soft
denture liners on raising the masticatory
efficiency when it is added to base of complete dentures
This study included ٢٥ patients ٣ groups .
When patients used complete dentures with
soft denture liner,
masticatory efficiency increased by ١١,٢٥٪ , there was gradual
healing (recovery ) of mucous membrane, and the patients
needed shorter time (٦-١٠ days) to accept their complete
dentures .
