Background: Recently tongue piercing has become increasingly popular in the society. Several case reports have presented various complications of tongue piercing. However, there is no scientific evidence about contact hypersensitivity to tongue piercing. Purpose: The aim of this study was to investigate the contact hypersensitivity after using tongue piercing. Methods: Nineteen male Rattus norvegicus were divided into three groups: group A treated with vaseline on the back and dorsum tongue (control group), group B (I) treated with HgCl2 10% cream on the tongue dorsum, group B (II) treated with tongue piercing for 10 days and group C with HgCl 2 10% cream on the back, ear lobe, and tongue, then re-exposure with same materials on ear, back and tongue for 24 and 48 hours. Before and after 24 and 48 hours applications, ear width was measured with sliding caliper. At the end of treatments, the rats were sacrificed. All tissue specimens were made for Hematoylin Eosine (H&E) staining examination. The number of mononuclear cells was counted under light microscope Data was analyzed with One-Way ANOVA followed by LSD (p<0.05). Results: The result of this study showed that there were a significant difference of the thickness of ear lobe and the number of mononuclear cells (lymphocyte and monocyte) among all groups. Conclusion: It is concluded that tongue piercing induce contact hypersensitivity.Latar belakang: Saat ini pemakaian tongue piercing sangat popular di masyarakat. Beberapa laporan kasus menunjukkan bahwa tongue piercing menimbulkan beberapa komplikasi. Namun, belum ada bukti ilmiah mengenai reaksi hipesensitivitas tongue piercing. Tujuan: Untuk mengetahui reaksi hipersensitivitas setelah menggunakan tongue piercing. Metode: Sembilan belas tikus jantan Rattus novergicus yang dibagi dalam tiga kemlompok yaitu: grup A diberi perlakuan dengan vaselin pada punggung dan dorsum lidah, grup B (I) diberi perlakuan dengan krim HgCl2 10% pada dorsum lidah dan B (II) perlakuan tongue piercing selama 10 hari. Grup C diberi perlakuan dengan HgCl2 pada punggung, daun telinga, dan dorsum lidah, kemudian diberi perlakuan ulang dengan bahan dan tempat yang sama selama 24 dan 48 jam. Sebelum dan setelah perlakuan selama 24 dan 48 jam ketebalan telinga diukur dengan sliding caliper. Setalah perlakuan tikus didekapitasi kemudian dibuat preparat jaringan untuk pemriksaan hematoxilin & eosin (H & E). Perhitungan jumlah sel mononuclear dilakukan menggunakan mikroskop cahaya.

Background: Nowadays, aesthetic rehabilitation becomes a necessity. It is affected by patient’s background, especially career, social and economic status. The aesthetic abnormality of anterior teeth i.e discoloration, malposition and malformation can affect patient’s appearance, especially during smile. These dental abnormalities, as a result, can decrease patient’s performance. Dental malformation, for instance, can be caused by developmental tooth defect, such as enamel hypoplasia. Enamel hypoplasia is a developmental defect caused by the lack of matrix amount which leads to thin and porous enamel. Enamel hypoplasia can also be caused by matrix calcification disturbance starting from the formation and development of enamel matrix causing defect and permanent changes which can occur on one or more tooth. Purpose: The aim of the study is to improve dental discoloration and tooth surface texture on anterior maxillary teeth with enamel hypoplasia by using indirect veneer with porcelain material. Case: A 20 years-old woman with enamel hypoplasia came to the Dental Hospital, Faculty of Dentistry Airlangga University. The patient wanted to improve her anterior maxillary teeth. It is clinically known that there were some opaque white spots (chalky spotted) and porous on anterior teeth’s surface. Case management: Indirect veneer with porcelain material had been chosen as a restoration treatment which has excellent aesthetics and strength, and did not cause gingival irritation. As a result, the treatment could improve the confidence of the patient, and could also make their function normal. Conclusion: Indirect veneer is an effective treatment, which can improve patient’s appearance and self confidence.Latar belakang: Saat ini perbaikan estetik menjadi suatu kebutuhan. Kebutuhan akan estetik dipengaruhi latar belakang penderita, terutama karir, status sosial dan ekonomi. Hal ini disebabkan, kelainan estetik seperti diskolorasi, malposisi, malformasi, dapat mempengaruhi penampilan penderita terutama saat tersenyum. Kelainan gigi tersebut pada akhirnya dapat memperburuk penampilan penderita. Malformasi gigi dapat disebabkan oleh kelainan pada masa perkembangan gigi, misalnya hipoplasia enamel. Hipoplasia enamel adalah kelainan perkembangan yang disebabkan sedikitnya matriks enamel sehingga terjadi ketipisan dan porusnya enamel. Hipoplasia enamel dapat disebabkan gangguan kalsifikasi matriks saat pembentukan dan perkembangan matriks enamel, kerusakan dan perubahan permanen ini dapat melibatkan satu atau beberapa gigi. Tujuan: Tujuan perawatan ini memperbaiki diskolorasi dan tekstur permukaan gigi depan rahang atas akibat hipoplasia enamel menggunakan veneer indirek berbahan porselen. Kasus: Seorang penderita wanita 20 tahun dengan hipoplasia enamel datang ke Rumah Sakit Gigi dan Mulut Pendidikan Fakultas Kedokteran Gigi Universitas Airlangga. Penderita ingin memperbaiki gigi depan rahang atas yang secara klinis tampak bercak putih opak seperti kapur dan porus pada permukan labial gigi. Tatalaksana kasus: Veneer indirek dengan bahan porselen dipilih sebagai restorasi oleh karena segi estetik, kekuatan dan tidak mengiritasi ginggiva. Restorasi ini dapat meningkatkan kepercayaan diri penderita dan memperbaiki fungsi gigi. Kesimpulan: Veneer indirek merupakan perawatan yang efektif, dapat meningkatkan penampilan dan kepercayan diri penderita.

Background: Losing posterior teeth for a long time would occasionally lead to the sharpening of alveolar process. The removable partial denture usually have problems when used during mastication, because of the pressure on the mucosa under the alveolar ridge. Purpose: The purpose of this case report was to manage patients with sharp mandibular alveolar process by wearing hybrid prosthesis with extra coronal precision attachment retention and soft liner on the surface base beneath the removable partial denture. Case: A 76 years old woman visited the Prosthodontic Clinic Faculty of Dentistry Airlangga University. The patient had a long span bridge on the upper jaw and a free end acrylic removable partial denture on the lower jaw. She was having problems with mastication. The patient did not wear her lower denture because of the discomfort with it during mastication. Hence, she would like to replace it with a new removable partial denture. Case management: The patient was treated by wearing a hybrid prosthesis with extra coronal precision attachment on the lower jaw. Soft liner was applied on the surface of the removable partial denture. Hybrid prosthesis is a complex denture consisting of removable partial denture and fixed bridge. Conclusion: It concluded that after restoration, the patient had no problems with sharp alveolar process with her new denture, and she was able to masticate well.Latar belakang: Kehilangan geligi posterior dapat menimbulkan processus alveolaris tajam. Gigi tiruan sebagian lepasan mempunyai masalah selama pengunyahan karena adanya tekanan di mukosa di bawah alveolar ridge. Tujuan: Tujuan laporan kasus ini adalah untuk menjelaskan cara menangani pasien yang mempunyai prosesus alveolaris yang tajam di rahang bawah dengan dibuatkan protesis hybrid dengan daya tahan extra coronal precision attachment dan soft liner di permukaan bawah basis gigi tiruan sebagian lepasan. Kasus: Pasien wanita berumur 76 tahun datang di klinik Prostodosia Fakultas Kedokteran Gigi Universitas Airlangga. Pasien memakai gigi tiruan lekat rentang panjang di rahang atas dan gigi tiruan sebagian lepasan akrilik free end di rahang bawah, pasien mengalami masalah waktu mengunyah. Pasien tidak memakai gigitiruan lepasan rahang bawahnya karena tidak nyaman dipakai, dan pasien menginginkan pembuatan gigi tiruan lepasan rahang bawah yang baru. Tatalaksana kasus: Pada pasien ini dilakukan pembuatan Hybrid Prosthesis dengan daya tahan berupa extra coronal attachment di rahang bawah dan penggunaan bahan pelapis lunak yang diaplikasikan pada basis gigi tiruan lepasan nya. Hybrid prosthesis adalah gigi tiruan himpunan yang terdiri dari gigi tiruan lepasan dan gigi tiruan lekat. Kesimpulan: Hasil perawatan menunjukkan setelah mengganti gigi tiruan dengan gigi tiruan sebagian lepasan yang baru, pasien tidak mempunyai masalah dengan gigi tiruan yang baru akibat processus alveolaris yang tajam dan pasien dapat mengunyah dengan baik.

Background: People usually used non steroid anti-inflammation drugs (NSAID) such as aspirin in chronic inflammation treatment. However, using NSAID at long term therapy will cause many effects such as nausea and vomiting. Sardinella longiceps oil, on the other side, is reported as an alternative treatment for anti-inflammation since it is natural and also contained eicosapentaenoid acid (EPA) and decohexaenoic acid (DHA). Thus, it may reduce paw oedema. Purpose: The aim of this study was to know anti-inflammation effects of Sardinella longiceps oil against paw oedema of Wistar rats induced by 1% carrageenan. Methods: The samples of this research were 32 Wistar rats which were divided into four groups, in group 1, the rats were given aquadest; in group 2, the rats were given aspirin; in group 3, the rats were given 1 ml Sardinella longiceps oil; in group 4, the rats were given 1.5 ml Sardinella longiceps oil. All of the rats, nevertheless, were given intraplantar induction of 1% carrageenan into the paw of rats to induce the inflammation condition. Results: All data were tested with normality test. The normal data were then analyzed with Homogenity of Variances and also ANOVA test which result showed significant differences. The data which showed significant differences were tested again with LSD test. result then showed that group given 1 ml Sardinella longiceps oil and group given 1.5 ml Sardinella longiceps oil had no significant differences from group given aspirin, but there were significant differences between group given 1 ml Sardinella longiceps oil and group given 1.5 ml Sardinella longiceps oil, and also between group given 1.5 ml Sardinella longiceps oil and group given aquadest. Conclusion: Sardinella longiceps oil could reduce paw oedema in Wistar rats induced with 1% carrageenan.Latar belakang: Penggunaan obat anti-inflamasi non steroid (OAINS) seperti aspirin sering digunakan dalam pengobatan inflamasi kronis. Namun penggunaan OAINS dalam jangka waktu panjang akan menyebabkan efek samping seperti mual dan muntah. Di sisi lain, minyak Sardinella longiceps, dilaporkan dapat digunakan sebagai alternatif anti-inflamasi karena selain alami, juga terdapat kandungan eicosapentaenoid acid (EPA) and decohexaenoic acid (DHA) yang dapat mengurangi edema pada telapak kaki. Tujuan: Tujuan dari penelitian ini adalah mengetahui efek anti-inflamasi minyak Sardinella longiceps pada edema telapak kaki tikus Wistar yang diinduksi karagenan 1%. Metode: Sampel penelitian ini adalah 32 tikus yang dibagi ke dalam empat kelompok. Kelompok 1, tikus diberi akuades; kelompok 2, tikus diberi aspirin; kelompok 3, tikus diberi minyak Sardinella longiceps 1 ml; kelompok 4, tikus diberi minyak Sardinella longiceps 1,5 ml. Semua tikus tidak terkecuali, diinduksi intraplantar karagenan 1% secara intraplantar pada telapak kaki untuk membuat kondisi inflamasi. Hasil: Semua data dilakukan uji normalitas. Selanjutnya data yang berdistribusi normal dilakukan uji homogenitas dan juga uji ANOVA yanng hasilnya menunjukkan adanya perbedaan bermakna. Data yang menunjukkan perbedaan bermakna diuji lagi dengan LSD. Pada uji LSD menunjukkan bahwa tidak ada perbedaan bermakna antara kelompok minyak Sardinella longiceps 1 ml dengan kelompok aspirin dan kelompok minyak Sardinella longiceps 1,5 ml dengan kelompok aspirin, tetapi ada perbedaan bermakna antara kelompok minyak Sardinella longiceps 1 ml dan kelompok akuades dengan kelompok minyak Sardinella longiceps 1.5 ml group given aquadest. Kesimpulan: Sardinella longiceps dapat mengurangi edema pada telapak kaki tikus Wistar yang diinduksi karagenan 1%.

Background: Tooth extraction can cause alveolar resorption, and will reduce the denture retention. The process of bone resorption looks like the process of osteoporosis. Calcium and vitamin D supplementation is the rational therapy for minimizing bone loss. Miacalcic is the drug of choice for osteporotic patient. Purpose: This study is aimed to know whether the combination of miacalcic, calcium lactate, and vitamin C are effective in inhibiting post extracted alveolar resorption. Methods: Thirty three healthy postmenopausal women were chosen as samples and they were classified randomly into control group (without treatment), 1st experiment group (treatment was started 3 months post extraction), and 2nd experiment group (treatment was started at the 2nd day post extraction). The treatment was done by giving miacalcic nasal spray, calcium lactate 500 mg and vitamin C 100 mg tablets every morning in 10 days every month for 3 months. X-ray photo of the post extracted area were taken an hour, 3 months, and 6 months post-extraction. Results: After 6 month, there was significant difference in buccolingual thickness decreasing among three groups (p<0.05). The maximum mean difference of buccolingual thickness decreasing was 0.72 mm, between control and 2nd experiment groups. There was no significant difference about decreasing bone density among them (p>0.10). The maximum difference of the mean of density decreasing was 1,906 g/cm2/mm between control and 2nd experiment groups. The increasing density mostly occurred in the 2nd experiment group. Conclusion: The combination of miacalcic, calcium lactate, and vitamin C are effective for inhibiting alveolar resorption, although statistically there was no significant difference about bone density decreasing. The sooner this treatment is given the better result will be achieved.Latar belakang: Pencabutan gigi menyebabkan resorpsi tulang alveolaris, dan akan mengurangi retensi geligi tiruan. Proses resorpsi tulang alveol pada osteoporosis mirip dengan proses resorpsi tulang pada penyembuhan luka bekas pencabutan. Miacalcic adalah obat utama untuk penderita osteoporosis. Kalsium dan vitamin D merupakan terapi yang rasional untuk meminimalkan resorpsi tulang. tujuan: Membuktikan apakah kombinasi miacalcic, kalsium laktat, and vitamin C juga efektif menghambat resorpsi tulang alveol pasca pencabutan. Metode: Sampel 33 wanita postmenopause yang sehat, terbagi secara acak ke dalam kelompok kontrol (tanpa perlakuan), kelompok eksperimen 1 (perlakuan mulai 3 bulan pasca pencabutan) dan kelompok eksperimen 2 (perlakuan mulai hari kedua pasca pencabutan). Perlakuannya yaitu: pemberian miacalcic semprot hidung, tablet kalsium laktat 500 mg dan vitamin C 100 mg setiap pagi, 10 hari dalam sebulan, selama tiga bulan. Foto sinar-X dari regio pasca pencabutan dibuat satu jam, 3 bulan, dan 6 bulan pasca pencabutan. Hasil: 6 bulan pasca-cabut, ada beda bermakna perihal selisih tebal bukolingual tulang alveol antar ketiga kelompok (p<0,05). Rerata penurunan ketebalan ini maksimal sebanyak 0.72 mm, antara kelompok kontrol dan kelompok eksperimen 2. Penurunan kepadatan tulang antar ketiga kelompok tidak bermakna (p>0,10). Beda maksimum rerata kepadatan tulang antara kelompok kontrol dan kelompok eksperimen 2 sebesar 1,906 g/cm2/mm. Peningkatan kepadatan terbanyak dialami anggota kelompok eksperimen 2. Kesimpulan: Kombinasi miacalcic, kalsium laktat, vitamin C efektif menghambat resorpsi tulang alveolaris, walaupun secara statistik beda penurunan kepadatan tidak bermakna. Makin awal pemberian perlakuan, hasilnya akan lebih baik.

Background: The decreased level of estrogen during menopause may be one of the risk factors of periodontal disease. The influence of estrogen to periodontal tissue disturbance is mediated by the presence of estrogen receptor on tissue. The precise mechanism how the estrogens mediate this effect is still unclear. Purpose: The aim of this study was to determine the correlation between estrogen receptor α and ß on the periodontal pocket of women who had severe chronic periodontitis measured based on the periodontal pocket depth. Methods: Twenty four periodontitis patients from menopausal and productive women according to the criteria were examined upon her periodontal status and immunoexpression of estrogen receptor α and ß on their periodontal pocket wall. Results: The result showed that in the menopausal and productive women, immunoexpression of estrogen receptor α and ß was not correlated with the periodontal pocket depth (p>0.05). However, the pocket depth seemed to show higher correlation with immunoexpression of estrogen receptor α than that with estrogen receptor ß, r=0.37 vs. r=0.12 for menopausal women, and r=41 vs. r=0.11 for productive women. Conclusion: It was concluded that no significant correlation was found between the estrogen receptor and periodontal pocket depth both on menopausal and productive women, presumed that estrogen has little role in the severity of periodontitis based on periodontal pocket depth. However, the estrogen receptor α has valuable effect on the severity of periodontal disease more than the estrogen receptor ß.Latar belakang: Berkurangnya kadar estrogen pada masa menopause merupakan salah satu faktor resiko penyakit periodontal. Peran estrogen dalam kerusakan jaringan periodontal dimediatori oleh reseptor estrogen α dan ß yang terdapat dalam jaringan. Akan tetapi, mekanisme estrogen mempengaruhi efek ini sampai saat ini masih belum jelas. Tujuan: Penelitian ini bertujuan untuk menentukan korelasi antara reseptor estrogen pada poket periodontal wanita menopause penderita periodontitis kronis dengan keparahan periodontitis yang ditentukan berdasarkan kedalaman poket. Metode: Dilakukan pemeriksaan status periodontal dan immunoekspresi reseptor estrogen α dan ß pada dinding poket periodontal dari 24 wanita menopause dan belum menopause penderita periodontitis yang sesuai dengan kriteria yang telah ditetapkan. Hasil: Hasil mendapatkan bahwa immunoekspresi reseptor estrogen α dan ß tidak berkorelasi dengan kedalaman poket periodontal wanita menopause dan belum menopause (p>0,05). Meskipun demikian, kedalaman poket periodontal tampak lebih berkorelasi dengan reseptor estrogen α daripada dengan reseptor estrogen ß, dengan nilai r=0,37 vs r=0,12 pada wanita menopause, dan r=0,41 vs r=0,11 pada wanita belum menopause. Kesimpulan: Dapat disimpulkan bahwa tidak terdapat korelasi yang signifikan antara reseptor estrogen dan kedalaman poket periodontal wanita menopause dan belum menopause sehingga diduga bahwa estrogen mempunyai sedikit pengaruh pada keparahan periodontitis. Meskipun demikian, reseptor estrogen α tampak lebih berperan terhadap keparahan penyakit periodontal dibandingkan reseptor estrogen ß.

Background: Nowadays, infectious disease still an important problem. One of the bacteria causing infectious diseases is Staphylococcus aureus (S. aureus). In the effort to deal with infections caused by S. aureus, beta-lactam antibiotics, such as ampicillin, are used. In fact, it is unfortunately known that many of S. aureus bacteria are resistant to this group of antibiotics. Because of nucleotide base changes in the structure of the genes blaZ which encode beta-lactamase enzymes in S. aureus. Purpose: The objective of this study was to analyze the nucleotide base changes in the structure of the genes blaZ forming beta-lactamase enzymes in S. aureus resistant to ampicillin based on molecular point of view. Methods: Molecular examinations was conducted by isolating the genes, forming beta-lactamase enzyme, which length was 845bp, from 7 isolates of S. aureus resistant to ampicillin by using PCR technique. The results of blaZ amplification were then subjected to homology by using Tn 552 of S. aureus obtained from bank of genes. Results: Based on the result of the homology, it was found that there was a change in purine base TG, which was a pyrimidine base at the -37 position of the initial codon of blaZ. This change, however, did not affect the strength of the promoter since the number of A and T is still more than the number of G and C. In the structure of the blaZ gene there was even no mutation or deletion or nucleotide base substitution found, so it would not affect the effectiveness of beta-lactamase enzyme. Conclusion: It can be concluded that the resistance of S. aureus towards ampicillin was not caused by nucleotide base deletion/substation. It is suspected that there were other causes leading to the resistance, including the overproduction of beta-lactamase enzyme of the blaZ gene, causing the degradation of beta-lactam antibiotics.Latar belakang: Penyakit infeksi sampai saat ini masih merupakan masalah. Salah satu bakteri penyebab infeksi yaitu Staphylococcus aureus (S. aureus). Upaya menangani infeksi yang disebabkan S. aureus dapat menggunakan antibiotik golongan betalaktam, salah satunya ampisilin. Pada kenyataannya banyak S. aureus resisten terhadap antibiotik ini. Salah satu penyebab timbulnya resistensi ampisilin terhadap S. aureus yaitu adanya dugaan perubahan basa nukleotida dari gen struktur (blaZ) yang mengkode enzim betalaktamase. Tujuan: Untuk menganalisis perubahan basa nukleotida gen struktur pembentuk enzim betalaktamase pada S. aureus yang resisten ampisilin ditinjau secara molekuler. Metode: Pemeriksaan enzim betalaktamase secara molekuler dilakukan dengan mengisolasi gen pembentuk ensim betalaktamase (blaZ) yang memiliki panjang 845 pb terhadap 7 isolat S. aureus hasil isolasi yang berasal dari abses yang resisten terhadap ampisilin dengan mengunakan PCR . Hasil amplifikasi blaZ kemudian dilakukan homologi dengan Tn 552 S. aureus yang diperoleh dari bank gen. Hasil: Hasil homologi ditemukan adanya perubahan basa purin T  G yang merupakan basa pirimidin pada posisi –37 dari kodon awal blaZ. Perubahan ini tidak mempengaruhi kekuatan promoter karena jumlah A dan T masih lebih banyak dari G dan C. Pada gen struktur blaZ ini tidak terdapat adanya mutasi ataupun delesi maupun subsitusi basa nukleotida hingga tidak akan mempengaruhi efektifitas kerja enzim betalaktamase. Kesimpulan: Terjadinya resisten S. aureus terhadap ampisilin bukan disebabkan adanya mutasi maupun delesi/ subsitusi basa nukleotida dari blaZ namun diduga adanya sebab lain yaitu produksi berlebih enzim betalaktamase hingga semua antibiotik betalaktam akan didegradasi oleh enzim betalaktamase.
