Abstract

Background: Prominent residual ridge is necessary to gain retention and stabilility for succesful prosthodontic treatment such as removable, fixed or implant. Spirulina is a natural substance that can help tissue healing and chitosan also a natural substance that reported to have the ability to help bone remodelling. The combination gel of spirulina and chitosan could be considered as an alternative material to maintain residual ridge height after tooth extraction. Purpose: The aim of study was to examine the effect of combination gel of Spirulina and chitosan on healing process of Cavia cobaya post tooth extraction socket by counting the amount of osteoclast, osteoblast and colagen as an indicator. Methods: Twenty eight cavia cobaya were divided into 4 groups. Insisive mandible extraction was done and the sockets were filled with 3% CMCNa for control groups, 3% spirulina chitosan 200 mg for group 1, 6% spirulina chitosan 200 mg for group 2, 12% spirulina chitosan 200 mg for group 3. After 30 days, histopathology examination was done by using microscope to count the amount of osteoclast, osteoblast and collagen. Results: Data was analyzed by using Anova and Tukey HSD. For osteoclast, there was no significant different between every groups, while for osteoblast and collagen there was significant different between groups. The results showed that induction of combination gel spirulina chitosan was able to accumulate collagen fiber and resulting faster wound healing. Conclusion: Combination 12% gel spirulina chitosan 200 mg could be used as an alternative material for better bone remodeling after tooth extraction.Latar belakang: Residual ridge yang prominen sangat dibutuhkan untuk mendapatkan retensi dan stabilitas untuk menunjang keberhasilan perawatan di bidang prostodonsia seperti pada kasus removable, fixed atau implant. Tindakan pencabutan gigi dapat merusak jaringan periodontal, sementum dan tulang alveolar yang mengakibatkan resorbsi ridge yang besar. Spirulina telah terbukti mempunyai kemampuan untuk membantu penyembuhan tulang sedangkan kitosan mempunyai kemampuan untuk membantu proses pembentukan tulang. Kombinasi kedua bahan ini diharapkan dapat menjadi bahan alternatif untuk mempercepat proses penyembuhan luka dan pembentukan tulang. Tujuan: Penelitian ini bertujuan meneliti efek induksi kombinasi gel dari Spirulina dan kitosan terhadap proses penyembuhan soket pasca ekstraksi gigi Cavia cobaya dengan indikator jumlah osteoklas, osteoblas dan kolagen. Metode: Penelitian ini menggunakan 28 marmot yang dibagi menjadi 4 kelompok penelitian. Pencabutan dilakukan pada incisive rahang bawah kemudian soket pencabutan diisi dengan CMCNa 3% pada kelompok control; spirulina 3% chitosan 200 mg pada kelompok perlakuan 1; spirulina 6 % chitosan 200 mg pada kelompok perlakuan 2, dan spirulina 12% citosan 200 mg pada kelompok perlakuan 3. Pada hari ke 30 dilakukan pemeriksaan histopatologi menggunakan mikroskop untuk menghitung jumlah osteoblas, osteoklas dan kolagen. Hasil: Data dianalisis dengan Anova dan Tukey HSD. Jumlah osteoklas tidak berbeda secara signifikan antara setiap kelompok, sedangkan jumlah osteoblas dan kolagen terdapat perbedaan yang signifikan antara kelompok. Hasil penelitian menunjukkan bahwa induksi kombinasi gel spirulina chitosan mampu mengakumulasi serat kolagen dan menghasilkan penyembuhan luka lebih cepat. Simpulan: Kombinasi gel spirulina 12% chitosan 200 mg dapat digunakan sebagai bahan alternatif untuk remodeling tulang yang lebih baik setelah pencabutan gigi.

Abstract

Background: Atrophic mandibular alveolar ridge generally complicates prostetic restoration expecially full denture. Low residual alveolar ridge and basal seat can cause unstable denture, permanent ulcer, pain, neuralgia, and mastication difficulty. Pre-proshetic surgery is needed to improve denture retention and stability. Augmentation is a major surgery to increase vertical height of the atrophic mandible while vestibuloplasty is aimed to increase the denture bearing area. Purpose: The augmentation and vestibuloplasty was aimed to provide stability and retentive denture atrophic mandibular alveolar ridge. Case: A 65 years old woman patient complained about uncomfortable denture. Clinical evaluate showed flat ridge in the anterior mandible, flabby tissue and candidiasis, while residual ridge height was classified into class IV. Case management: Augmentation using autograph was conducted as the mandible vertical height is less than 15 mm. Autograph was used to achieve better bone quantity and quality. Separated alveolar ridge was conducted from left to right canine region and was elevated 0.5 mm from the previous position to get new ridge in the anterior region. The separated alveolar ridge was fixated by using T-plate and ligature wire. Three months after augmentation fixation appliances was removed vestibuloplasty was performed to increase denture bearing area that can make a stable and retentive denture. Conclusion: Augmentation and vestibuloplasty can improve flat ridge to become prominent.Latar belakang: Ridge mandibula yang atrofi pada umumnya mempersulit pembuatan restorasi prostetik terutama gigi tiruan lengkap (GTL). Residual alveolar ridge dan basal seat yang rendah menyebabkan gigi tiruan menjadi tidak stabil, menimbulkan ulser permanen, nyeri, neuralgia, dan kesulitan mengunyah. Tujuan: Augmentasi dan vestibuloplasti pada ridge mandibula yang atrofi dilakukan untuk menciptakan gigi tiruan yang stabil dan retentive. Kasus: Pasien wanita usia 65 tahun datang dengan keluhan gigi tiruan yang tidak nyaman. Pemeriksaan klinis menunjukkan ridge flat pada anterior mandibula, jaringan flabby dan kandidiasis, sedangkan residual ridge digolongkan menjadi kelas IV. Tatalaksana kasus: Augmentasi dilakukan karena ketinggian vertikal mandibula kurang dari 15 mm. Autograf digunakan untuk mendapatkan kuantitas dan kualitas tulang yang lebih baik. Alveolar ridge diambil dari sisi kiri dan kanan region kaninus dan digunakan 0,5 mm dari posisi awalnya untuk mendapatkan ridge baru pada region anterior. Alveolar ridge telah diseparasi difiksasi menggunakan T-plate dan ligature kawat. Tiga bulan setelah fiksasi dilepas, dilakukan vestibuloplasti untuk meningkatkan denture bearing area sehingga gigi tiruan lebih stabil dan retentive. Kesimpulan: Augmentasi dan vestibuloplasti dapat memperbaiki ridge atrofi sehingga menjadi tinggi kembali.

Abstract

Background: Tooth extraction is the ultimate treatment option for defective teeth followed by the need for dentures. Inflammation is one phase of the healing process that should be minimized in order to preserve alveolar bone for denture support. Macrophage, PMN and lymphocyte cells are indicators of acute inflammation. Spirulina and chitosan are natural compounds with the potential to be anti-inflammatory agents. Purpose: This research aimed to determine macrophage, PMN and lymphocyte cells of animal models treated with a combination of 12% spirulina and 20% chitosan on the 1st, 2nd and 3rd post-extraction day. Methods: Animal models were randomly divided into control (K) and treatment (P) groups. Each group was further divided into three subgroups (KI, KII, KIII and PI, PII, PIII). The post-extraction sockets of the control group animals were then filled with CMC Na 3%. Meanwhile, the post-extraction sockets of the treatment group members were filled with a combination of 12% spirulina and 20% chitosan. Subsequently, the number of PMN, macrophage and lymphocyte cells was analyzed by means of HE analysis on the 1st., 2nd. and 3rd. days. Statistical analysis was then performed using a T-test. Results: There was a decrease in PMN cells and an increase in macrophage and lymphocyte cells on Days 1, 2, and 3. Conclusion: It can be concluded that a combination of 12% spirulina and 20% chitosan can not only decrease PMN cells, but can also increase macrophage and lymphocyte cells on Days 1, 2 and 3 after tooth extraction.

Abstract

Background: Poor bone quality, sometimes caused by osteoporosis, can lead to dental implant failure. Human umbilical cord mesenchymal stem cells (hUCMSCs) can differentiate into osteoblasts and offer an alternative therapy for poor bone conditions. Purpose: This study aims to evaluate the effect of hUCMSCs induction on the extent of osseointegration by the new bone formation area of dental implants in osteoporotic animal models. Methods: The samples were divided into two groups, i.e., control and induced hUCMSCs groups at different times. An ovariectomy was performed to assess the osteoporosis condition. The control group was injected using gelatin, and the treatment group was administered hUCMSCs. Terminations were conducted at 2 and 4 weeks, respectively. The collected samples were then subjected to histological examination to analyze new bone formation and its proportion. In addition, alkaline phosphatase staining was also performed to evaluate the mineralization area. The data was analyzed using the one-way analysis of variance (ANOVA). Results: Both for new bone formation area as well as the proportion of new bone, it was observed that the best results were in the group with induction of hUCMSCs at 2 weeks. Alkaline phosphatase staining also confirmed that the highest mineralization was observed in the same group. Conclusion: hUCMSCs induced new bone formation in the implant placement in osteoporotic animal models.
