Fibrous Lesions Of The Gingiva: A Histopathologic Analysis Of 204 Cases, Rosnah Binti Zain, Fei Y. J. Oct 1990

Fibrous Lesions Of The Gingiva: A Histopathologic Analysis Of 204 Cases, Rosnah Binti Zain, Fei Y. J.

Prof. Dr. Rosnah Binti Zain

Two hundred four cases of fibrous lesions of the gingiva were studied histologically for the presence of calcified tissue, the nature of the connective tissue, the type of keratinization, and the degree of epithelial thickness. Initially these lesions were subcategorized into four specific entities, namely fibrous epulis, fibroepithelial polyp, calcifying fibroblastic granuloma, and ossifying fibrous epulis. It was found that 46.5% of the lesions contained calcifications. The connective tissue was represented predominantly by either the collagenous type (50.5%) or the mixed (cellular and collagenous) type (44.6%). It was also found that 36% of the lesions were ulcerated, and, of these, …

Radiographic Features Of Periapical Cysts And Granulomas, Rosnah Binti Zain, Roswati N., Ismail K. Jan 1989

Radiographic Features Of Periapical Cysts And Granulomas, Rosnah Binti Zain, Roswati N., Ismail K.

Prof. Dr. Rosnah Binti Zain

Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts and granulomas in the hope to identify features that maybe suggestive of either diagnosis. The results showed that a regular (circular or semi-circular) radiographic outline is likely to be a periapical cyst while an irregular radiographic outline is not indicative of either a …

Radiographic Evaluation Of Lesion Sizes Of Histologically Diagnosed Periapical Cysts And Granulomas, Rosnah Binti Zain, Roswati N., Ismail K.

Prof. Dr. Rosnah Binti Zain

A total of 149 periapical lesions were classified histologically into cysts, granulomas and other lesions. It was found that 53% were cysts, 39% were granulomas and 8% were other lesions. Of the 149 periapical lesions classified, 69 selected cases of cysts and granulomas were obtained and radiographic measurements of area (mm2), largest diameter (mm) and largest root-to-border distance (mm) were recorded. It was found that there is an apparent increase in cystic prevalence with an increase in the area, largest diameter or largest length of the periapical lesions radiographically. A cystic prevalence of 92-100% is observed with a radiographic area …

Prof. Dr. Rosnah Binti Zain

The prevalence of clinically observed oral lichenoid reaction in 186 Malay army personnel using Fansidar for 9 weeks was found to be 4.8%. The prevalence was found to be 0.5% in 186 army personnel who had stopped using Fansidar for 2 months and 0% in 143 army personnel (control group) who had not used Fansidar for at least 4 months. The lesion showed a higher prevalence for the gingiva. There was no correlation between cigarette smoking and the occurrence of these lesions in each group

Morphological Changes In Taste Buds Of The Fungiform Papillae After A Single Dose Of X-Ray Irradiation In Rats, Rosnah Binti Zain, Hanks C. T.

Prof. Dr. Rosnah Binti Zain

The qualitative and quantitative changes occurring in the taste buds of the fungiform papillae of male Sprague-Dawley rats (aged 51-125 days old) after x-ray irradiation were studied. A single dose of 2000 Roentgen (R) was delivered and observations were made at 0, 3, 7, 14, 21 and 30 days after x-ray irradiation. The changes in taste bud morphology were interpreted first as degenerative and then as regenerative at various stages of the study. The degenerative process appeared at about the third day and reached a peak at 7 days. Regeneration then began after a further week and the taste buds …

The Cracked Tooth Syndrome--Crown Root Vertical Fracture, Rosnah Binti Zain, Majid Z. A.

Prof. Dr. Rosnah Binti Zain

A case of an incomplete tooth fracture followed by a complete fracture was presented. The difficulty of diagnosing this condition was discussed as well as the possible histological explanation of the symptoms experienced by the patient. It once again points out to practising dentists, that whilst deep pockets can give rise to severe periodontal pain, intense and excruciating pain should be investigated with the cracked tooth in mind.

Peripheral Ossifying Fibroma/Ossifying Fibrous Epulis, Rosnah Binti Zain, Janakarajah N. Jan 1988

Peripheral Ossifying Fibroma/Ossifying Fibrous Epulis, Rosnah Binti Zain, Janakarajah N.

Prof. Dr. Rosnah Binti Zain

This is a case report of a reactive lesion which occurs only in the gingiva. This lesion is of a long duration causing erosion of the superficial bone. Histologically it is similar to other epulides of the gingiva but in addition contains ossified tissue. The lesion's confusing terminology is being discussed in view of its understanding to an American-trained or a British-trained surgeon. A review of literature showed a recurrence rate of 7-20% thus making it mandatory for a close follow-up of the patient.

Traumatic Granuloma/Eosinophilic Ulcer, Rosnah Zain, Abdul Hamid J., Awang M. N. Jul 1986

Traumatic Granuloma/Eosinophilic Ulcer, Rosnah Zain, Abdul Hamid J., Awang M. N.

Prof. Dr. Rosnah Binti Zain

Two case reports of an uncommon type of oral ulcerative lesion are presented. These lesions are of long duration, benign and reactive, and may clinically mimic a malignant ulcer. Histologically, these are deep lesions which exhibit 'pseudoinvasion' into skeletal muscle. There is a predominance of eosinophils while other chronic inflammatory cells such as plasma cells and histiocytes are in abundance. A brief review of the literature showed past treatment being surgical excision, incisional biopsy, radiation, cryosurgery with liquid nitrogen and no treatment. All modalities used result in resolution of the lesion.

Clinical Presentation Of Buccal Carcinoma. A Review Of Twenty Nine Patients, Janakarajah N., Rosnah Binti Zain

Prof. Dr. Rosnah Binti Zain

29 patients with buccal carcinoma were reviewed for the clinical signs and symptoms. The TNM classification following the UICC categories were used for the clinical staging of the lesion. The patient’s race, age, sex and habits were also noted. Most of these patients presented with advanced lesions. The most common signs and symptoms were pain and ulcerations (62%). The histopathology of a well-differentiated squamous cell carcinoma forms a great majority of these lesions (62%). Each of the sign and symptom is discussed in relation to other findings that had been reported.
