ABSTRACT Background: Oral submucous fibrosis (OSMF) is graded according to various histological factors which include the epithelial changes and the connective tissue changes. These features could be identified in routine Hematoxylin and Eosin (H and E) staining in shades of pink. However, the use of special stains provides a contrast to various connective tissue components thereby aiding in better visualization of these connective tissue changes in advanced OSMF cases. Objective: To compare and evaluate muscle involvement and degeneration in advanced oral submucous fibrosis using three different stains namely, H&E, Van Gieson, and Masson’s Trichrome. Material and Methods: 10 Formalin-fixed paraffin-embedded tissue sections of advanced OSMFwere stained using 3 different stains namely Hematoxylin and Eosin (H&E), Van-Gieson, and Masson trichrome. The results obtained were tabulated and statistically analyzed using Kruskal Wallis ANOVA. Results: The hyalinization and fibrosis involving the skeletal muscle were better visualized in Masson’s Trichrome but were not statistically significant. The muscle degeneration in deeper areas was better visualized in Masson’s trichrome when compared to the H&E and Van Gieson. Conclusion: Hematoxylin and eosin stains all the connective tissue components in various shades of pink, use of special stains bestows contrast between different components of connective tissue, thus improvising grading of OSMF. Masson’s trichrome stain can be used as a single adjunct to hematoxylin and eosin stain as changes in the superficial and deeper connective tissue could be ascertained.

Kebiasaan menyirih telah dilakukan sejak dahulu kala di Indonesia, khususnya pada suku Papua. Banyak anggapan masyarakat bahwa menyirih dapat menguatkan gigi geligi dan menghambat terjadinya karies, namun dibalik dampak positif dari menyirih ini, ada juga dampak negatifnya berupa timbulnya lesi pada mukosa yang melapisi rongga mulut.Tujuan penelitian ini yaitu untuk memperoleh gambaran kebiasaan menyirih pada mahasiswa Papua di Kota Manado, mencakup: tujuan menyirih, bahan campuran menyirih, lamanya kebiasaan menyirih, frekuensi menyirih, dan faktor pendorong kebiasaan menyirih serta untuk mengetahui gambaran lesi mukosa mulut pada mahasiswa Papua di Kota Manado.Jenis penelitian ini yaitu penelitian desktiptif dengan pendekatan cross-sectional study. Teknik pengambilan sampel yang digunakan ialah total sampling dengan jumlah sampel 30 orang. Dari 30 subjek yang diperiksa, sebagian besar merupakan wanita, usia 17-27 tahun. Lamanya menyirih terbanyak 6-10 tahun, dengan frekuensi terbanyak 1-3 kali sehari, bahan campuran menyirih yang paling banyak digunakan ialah campuran sirih, pinang dan kapur. Faktor pendorong utama menyirih yakni karena keinginan sendiri, dimana tujuan menyirih terbanyak yakni agar gigi menjadi kuat dan sehat. Dari 30 subjek ada 29 orang (96,66%) memiliki lesi dalam rongga mulutnya. Lesi yang diduga sebagai Oral Submucous Fibrosis yakni sebanyak 90% dan lesi yang diduga sebagai Betel Chewers Mucosa sebanyak 6,66%.Kata kunci: Kebiasaan menyirih, lesi mukosa mulut, Oral Submucous Fibrosis, Betel Chewer’s MucosaABSTRACTBetel chewing as a habit has been done since a long time ago in Indonesia, especially in Papua. There are some public perceptions that betel chewing can strengthen teeth and prevent caries. But, behind the positive effect of betel chewing, there are negative effects too, such as the onset of lesions in the oral mucosa.The purpose of this research is to get an overview of betel chewing habit on Papuan students in Manado, including the purpose of betel chewing, the complete material of betel chewing, duration of betel chewing, frequency of betel chewing, the driving factor of betel chewing, and to get an overview on oral mucosal lesions on Papuan students in Manado.The type of this research is descriptive research with a cross - sectional study. The sampling technique is total sampling with a sample size of 30 people. The 30 examined subjects, mostly women with age ranging from 17-27 years. The most length of chewing from 6-10 years, with the highest frequency of chewing 1-3 times a day, the average mixture of betel commonly used is betel, areca nut and slaked lime. The major driving factor in betel chewing is their own desire and the most common purpose is to get a strong and healthy teeth. 29 of 30 subjects (96,66%) have lesions in the oral cavity. In 90% of the sample, expected as Oral Submucous Fibrosis and in 6,66% expected as Betel Chewer’s Mucosa.Keyword: Betel chewing habit, oral mucosal lesions, Oral Submucous Fibrosis, Betel Chewer’s Mucosa

<p><strong>Background:</strong> Oral submucous fibrosis (OSMF), a potentially malignant oral disorder has the highest rate of malignant transformation of about 7-13%. The connective tissue changes that occur in this disease are characteristic and are stained with special stains.</p><p><strong>Objective:</strong> The study was done to compare common and special stains under light microscopy and polarizing microscopy to evaluate the levels of fibrosis in oral submucous fibrosis and assess the type of collagen present in the stromal area.</p><p><strong>Materials and Methods:</strong> Fifty tissue blocks were selected from the archives and were prepared and stained with H&amp;E, Masson's trichrome, Van Gieson and Picrosirius red and studied under light microscope and polarizing microscope respectively.</p><p><strong>Results:</strong> H and E stained slides were useful in diagnosing the lesion but was not able to highlight the level of fibrosis. Masson's trichrome and Van Gieson stained slides showed the depth of the lesion which extended even to the deeper muscle layer. The type of collagen present was definitively seen by the birefringence in polarizing microscopic study. Interobserver variation was less and all the values regarding the effectiveness of the special stains in detecting the level of fibrosis were statistically significant.</p><p><strong>Conclusion:</strong> Special stains can be used routinely in laboratories to demonstrate connective tissue lesions especially in cases of OSMF. Depth of the lesion and the area of involvement help in treatment planning to be delivered. Large scale studies with more categories and inclusion criteria are required along with the special stains to assess the other alterations in OSMF.</p>

Aim and Objectives. Oral submucous fibrosis (OSF) is a potentially malignant disorder associated with the usage of areca nut. Usage of processed forms of areca nut is popular among the youth and its carcinogenic effects are not well known. Due to large immigrant population, various patterns of areca nut usage are seen. The aim of this study is to assess the various quid chewing patterns and their association with severity of OSF.Materials and Methods. A cross-sectional study was carried out with 250 cases clinically and histologically diagnosed as having OSF lesion that were selected and subjected to a detailed habit history which was recorded through preformed questionnaire. The data obtained was statistically analyzed.Results. Among the 250 subjects, males were seen to be affected more than females within the age group of 26–35 years and were having clinical stage I OSF. A combination of processed areca nut and processed tobacco was used by the majority of the subjects with duration of 1 to 5 years, at a frequency of 3 to 5 quids per day.Conclusion. The present study confirms the association between oral submucous fibrosis and the quid containing processed areca nut and processed tobacco and also highlights the increasing youth population using the processed forms of areca nut.
