"Latar Belakang: Kista dan tumor odontogenik merupakan aspek yang sering dibahas dan cukup penting dalam bidang bedah maupun patologi oral dan maksilofasial. Secara radiografi gambaran kista dentigerous, odontogenic keratocyst (OKC), dan ameloblastoma unikistik memiliki kemiripan berupa lesi radiolusen unilocular. Pada hasil pemeriksaan histopatologi dengan pewarnaaan hematoksilin eosin ketiga lesi ini dapat dibedakan, namun banyak ahli patologi yang mengalami misdiagnosa dikarenakan kemiripannya. Calretinin merupakan protein pengikat kalsium yang sudah banyak digunakan untuk penanda keganasan pada jaringan tubuh manusia, dikarenakan perannya dalam apoptosis sel yang menyebabkan terjadinya proliferasi sel. Tujuan: untuk melihat dan membandingkan ekspresi Calretinin pada kista dentigerous, OKC, dan ameloblastoma unikistik. Metode: 34 blok parafin kista dentigerous, OKC dan ameloblastoma unikistik didapatkan secara consecutive sampling dari data rekam medik di Divisi Bedah Mulut RSCM yang telah dilakukan konfirmasi hasil histopatologinya di Departemen Patologi Anatomi RSCM selama periode 2015- 2019. Seluruh sampel dilakukan pemeriksaan imunohistokimia menggunakan antibodi Calretinin. Hasil: didapatkan 13 sampel kista dentigerous (38,2%), 6 sampel OKC(17,6%), dan 15 sampel ameloblastoma unikistik(44,2%). Yang terintepretasi positif Calretinin sebanyak 1 sampel kista dentigerous (2,9%) dan 11 sampel ameloblastoma unikistik(32,3%), namun tidak ada sampel OKC (0) yang terintepreatsi positif. Secara statistik dengan uji chi-square didapati hasil berbeda bermakna(p=0,001) dengan odd ratio (OR) sebesar 49,5 antara kelompok ameloblastoma unikistik dan kelompok bukan amleoblastoma unikistik. Kesimpulan: Calretinin terekspresi pada kista dentigerous dan ameloblastoma unikistik dengan persentase yang berbeda, namun tidak pada OKC. Calretinin dapat dijadikan penanda spesifik untuk ameloblastoma unikistik.

Background: Odontogenic cysts and tumors are aspects that often discussed and quite important in the field of either oromaxillofacial surgery or pathology. Radiographically, the dentigerous cyst, odontogenic keratocyst (OKC), and unicystic ameloblastoma have a similar appearance in the form of unilocular radiolucent lesions. As a results of histopathological examination with hematoxylin eosin staining, these three lesions can be distinguished, however, many pathologists are misdiagnosed because of their similarity. Calretinin is a calcium binding protein that has been widely used for markers of malignancy in human tissues, due to its role in cell apoptosis which causes cell proliferation. Objective: This study aims to observe and compare Calretinin expression in dentigerous cysts, OKC, and unicystic ameloblastoma. Methods: 34 paraffin blocks of dentigerous cysts, OKC and unicystic ameloblastoma were obtained by consecutive sampling from medical record data in RSCM, Oral Surgery Division which had confirmed histopathological results at the Department of Anatomical Pathology RSCM during the period 2015-2019. All samples were subjected to immunohistochemical staning using Calretinin antibodies. Results: 13 samples of dentigerous cysts, 6 samples of OKC, and 15 samples of unicystic ameloblastoma were obtained. The positive interpretation of Calretinin was 1 sample of dentigerous cyst and 11 samples of unicystic ameloblastoma. Conclusion: Calretinin was expressed in dentigerous cysts and unicystic ameloblastoma with different percentages, but not in OKC. Calretinin can be used as a marker for unicystic ameloblastoma"

"The purpose of the study to seek the differences of cell proliferation index among dentigerous cyst. dentigerous with ameloblastoma and ameloblastoma plexiform. This study utilized retrospective methode,which was achieved by collecting data from medical record in oral surgery clinic. Cipto Mangunkusumo Hospital and Pathology Anatomy Laboratory at Faculty of Medicine University of Indonesia from January 1998 to April 2002. Histological examination were prepared from 34 samples; consist of 15 dentigerous cysts, 11 ameloblastoma and 8 dentigerous cyst which arise with ameloblasroma. ln each case, intra-nuclear AgNOR dots were counted in 100 consecutive basal nuclei. Statistic analysis using ANOVA show the difference among study objects (p<0.05). AgNOR an ameloblastoma is significantly higer than in dentigerous cyst. The differences may indicate the variation of metabolic, proliferation of transcriptional activities of the cell. The study found the difference of AgNOR count in cell proliferation index among dentigerous cyst, dentigerous cyst which arise with ameloblastoma and ameloblastoma. The finding can be used to determine the diagnoses in doubtfull cases where dentigerous and ameloblastoma cannot be distinguished clinically and pathologically."

ABSTRACTBackground Apical constriction is the smallest diameter of root canal system and also the most commonly used reference point by clinicians as the apical termination for cleaning, shaping, and obturation for root canal treatment. Objective This study aim to know the variation of size, location, and shape of apical constriction in mandibular first premolar and maxillary second premolar. Methods Total 66 samples of extracted premolar teeth with perfectly formed root and without sign of external resorption were collected. Each tooth was scanned using a Bruker Skyscan 1173 micro CT at a resolution of 50 m. The teeth were made transparent in order to reveal the root canal system morphology in three dimensions. The size, location, and shape of apical constriction was analyzed using Fiji ImageJ, CT Vox, CT An, and CT Vol software. Data were analyzed statistically by One sample T test. Result The average distance between apical constriction and apical foramen in mandibular first premolar is 0,619 mm and in maxillary second premolar is 0,647 mm with the most location of apical constriction inclining to apically. Most of apical constrictions shape in mandibular first premolar and maxillary second premolar is convergent apical constriction and branched apical constriction. Conclusion The variation of size, location, and shape of apical constriction should be considered by dentist in performing endodontic treatment."

"ABSTRAKLatar belakang: Endometriosis merupakan kelainan ginekologik yang paling sering ditemukan. Seperti halnya endometrium di uterus juga dapat terjadi berbagai perubahan pada epitel yang melapisi kista endometriosis di ovarium, antara lain metaplasia, hiperplasia, atipia bahkan perubahan ke arah keganasan. Saat ini banyak penelitian yang menghubungkan antara endometriosis dan kanker ovarium terutama jenis clear cell dan dikenal dengan istilah endometriosis-associated ovarian carcinoma (EAOC) dan dilaporkan adanya mutasi yang menginaktifkan gen supresor tumor (ARID1A), sehingga protein BAF250a tidak diekpresikan pada Clear cell carcinoma (CCC) ovarii.Bahan dan cara: Dilakukan pulasan imunohistokimia ARID1A pada sampel 20 kasus endometriosis non atipik, 20 kasus atipik dan 20 kasus CCC ovarii tahun 2012 hingga Maret 2015. Dari kelompok kasus CCC didapatkan 9 kasus EAOC. Selanjutnya dilihat adakah perbedaan persentase ekspresi ARID1A pada endometriosis non atipik, atipik, CCC ovarii serta endometriosis disertai CCC (EAOC).Hasil: Pada kelompok kasus endometriosis non atipik, atipik dan CCC ada perbedaan bermakna persentase ekspresi ARID1A (uji Kruskal-Wallis p=0,0035). Selanjutnya dilakukan analisis Post Hoc uji Mann-Whitney dan didapatkan perbedaan bermakna persentase ekspresi ARID1A antara endometriosis non atipik dan atipik dengan CCC ovarii (p=0,001 dan p=0,0015). Pada kelompok kasus endometriosis non atipik, atipik dan endometriosis pada EAOC, didapatkan ada perbedaan bermakna persentase ekspresi ARID1A (Uji Kruskal-Walis p=0,011). Selanjutnya dilakukan analisis Post Hoc uji Mann-Whitney dan ada perbedaan bermakna persentase ekspresi ARID1A antara endometriosis non atipik dan atipik dengan EAOC (p=0,005 dan p=0,008).Kesimpulan: Ekspresi ARID1A pada endometriosis non atipik dan atipik lebih tinggi bermakna dibanding CCC ovarii dan EAOC. Sehingga ekspresi ARID1A kemungkinan dapat digunakan sebagai petanda adanya transformasi ganas pada endometriosis.

ABSTRACT

Background: Endometriosis is one of the most common gynecological abnormalities found. Endometriosis cyst in the ovary also exhibited changes in epithelial cyst just like endometrium in the uterus. Changes in the epithelial cells also include metaplasia, hyperplasia, atyphia even changes toward malignan characteristics. Nowadays, there are some research that linked endometriosis and clear cell ovarian cancer which is known with endometriosis-associated ovarian carcinoma (EAOC) it is reported that there?s a mutation that activated tumor suppressor gene (ARID1A), so protein BAF250a is not expressed in Clear Cell Carcinoma (CCC) in the ovarium.

Materials and Methods: Immunohistochemistry staining of ARID1A were done in 20 samples of non-atypical endometriosis, 20 samples of atypical endometriosis, 20 samples of CCC in the ovarium from the year 2012 until march 2015. From the group that experienced CCC we get 9 cases of EAOC. After that, we see if there?s any difference in the percentage of ARID1A expression in non-atypical endometrosis, atypical endometriosis, CCC in the ovarium and endometriosis with CCC( EAOC).

Results: In non-atypical endometriosis, atypical and CCC cases groups there are significant differences on the percentage of ARID1A expression (Kruskal-Walis test p=0,0035). Post Hoc analysis were done using Mann-Whitney test and there are significant differences on ARID1A expression between non-atypical and atypical endometriosis with CCC (p=0,001 and p=0,0015). In non-atypical endometriosis, atypical and EAOC groups there are significant differences on the percentage of ARID1A expression (Kruskal-Walis test p=0,011). Post Hoc analysis were done using Mann-Whitney test and there are significant differences on ARID1A expression between non-atypical and atypical endometriosis with EAOC (p=0,005 and p=0,008).

Conclusion: Expression of ARID1A in non atypical and atypical endometriosis are significantly higher compared to ovarian CCC and EAOC. So, we can say that ARID1A may be used as a marker for malignancy transformation in endometriosis."

"A reimplantation case of maxillary second incisive with periapical (radicular) cyst is reported. A 37 years old female who suffered periapical cyst on her maxillary second incisive requested conventional endodontic treatment in order to avoid to avoid tooth extraction. The tooth was treated with a conventional root canal treatment at the first visit. After the first treatment, the patient suffered a post endodontic treatment pain but was afraid to be operated with apex resection. On the second visit, the maxillary second incisive was extracted. On the third visit the patient requested periapical cyst removal after she received advices from her older sister (who was a medical doctor) about the important of removing cyst capsule in order to avoid cyst recurrency. The patient also requested her tooth reimplantation. Following her request, on her extracted maxillary second incisive, root canal filling and apex resection were done out side her mouth, followed by periapical curettage in the maxillary second incisive region. Then reimplantation was finally performed. Seven months later, the patient told that since her maxillary second incisive apex resection and reimplantation, she never suffered from any pain or swelling. Pain on the tooth percussion and palpation were negative. Tooth mobility was on level 2. There was no sign that periapical radiolucency was growing wider, eventhough it was not getting smaller at that moment. We classified the result of our treatment as "not fail" since we still need a longer time ensure wether or not the result will be able to be classified as "successful". Eventhough radiographic healing was still "uncertain", there was a hope that the patient will gain a "complete healing" after 2 years."
