Association Between Cigarette-Smoking And Prevalence Of Oral Mucosal Lesions Among Malaysian Army Personnel, Rosnah Binti Zain, Razak I. A.
Association Between Cigarette-Smoking And Prevalence Of Oral Mucosal Lesions Among Malaysian Army Personnel, Rosnah Binti Zain, Razak I. A.
Prof. Dr. Rosnah Binti Zain
The association between cigarette smoking and the prevalence of oral mucosal lesions was examined in 495 Malaysian army personnel. No associations between cigarette smoking and recurrent aphthous ulcerations, pre-leukoplakia and frictional keratosis could be obtained in this study. Positive associations were found between cigarette smoking and leukoedema as well as denture stomatitis. There was a negative association between cigarette smoking and the presence of coated tongue.
The Social Impact Of Oral And Facial Pain In An Industrial Population, Rosnah Binti Zain
The Social Impact Of Oral And Facial Pain In An Industrial Population, Rosnah Binti Zain
Prof. Dr. Rosnah Binti Zain
The aim of this study is to determine the social impact of oral and facial pain in a sample involving an industrial population. Out of a total of 355 subjects interviewed, nearly one-half claimed to have oral and facial pain in the previous one month prior to the survey. The most common type of pain was that related to hot or cold fluids or sweet things followed by toothache. On the average, the pain lasted for 4.2 days (SD = 4.9) per person in the past one-month. About one in five persons with pain reported that it was severe enough …
Radiographic Features Of Periapical Cysts And Granulomas, Rosnah Binti Zain, Roswati N., Ismail K.
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.
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 …
Oral Lichenoid Reactions During Antimalarial Prophylaxis With Sulphadoxine-Pyrimethamine Combination, Rosnah Binti Zain
Oral Lichenoid Reactions During Antimalarial Prophylaxis With Sulphadoxine-Pyrimethamine Combination, Rosnah Binti Zain
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.
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 Occurrence Of Oral-Mucosal Lesions Among Employees Of A Steelmill--A Preliminary Study, Rosnah Binti Zain, Koh L. S.

Prof. Dr. Rosnah Binti Zain
A study has been conducted on 198 employees of a steel-mill industry. These participants were examined for mucosal lesions in the oral cavity and including the commissures and vermillion borders of the lips. The prevalences of 16 types of lesions are reported.
The Dental Health Of Factory Workers In Pasir Gudang, Johor (Malaysia), Abdul Majid Z., Rosnah Binti Zain
The Dental Health Of Factory Workers In Pasir Gudang, Johor (Malaysia), Abdul Majid Z., Rosnah Binti Zain
Prof. Dr. Rosnah Binti Zain
A study on the oral health status of 198 factory workers (in Antara Steel, Pasir Gudang, Johor) was carried out in November 1986. The subjects were predominantly male (94%) and Malay (91%) with an average age of 27.4 years. The prevalence of caries was 87.4% with a mean DMFT of 7.1 + 5.4. There were 3 subjects with full upper, lower dentures and 16 subjects with partial dentures. Two subjects examined needed dentures but were not wearing them. Thirty five (17.7%) of those examined needed urgent extractions, and 8 needed emergency treatment for fillings. Enamel opacities were found in 141 …
The Cracked Tooth Syndrome--Crown Root Vertical Fracture, Rosnah Binti Zain, Majid Z. A.
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.
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.
Oral Lichenoid Drug Reaction, Rosnah Binti Zain, Nor G. M.
Oral Lichenoid Drug Reaction, Rosnah Binti Zain, Nor G. M.
Prof. Dr. Rosnah Binti Zain
This is a case report of an oral lichenoid drug reaction of the buccal sulci in a female diabetic patient who was on an anti-hypertensive drug, alpha-methyldopa (Aldomet) and an oral hypoglycaemic drug, chlorpropamide (Diabinese). The clinical features, histological findings and management are presented.
Traumatic Granuloma/Eosinophilic Ulcer, Rosnah Zain, Abdul Hamid J., Awang M. N.
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
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.
