"Titanium mesh is used in orthopedic surgery as a barrier membrane, as it offers suitable characteristics, which allow mechanical support during the formation of new bone. An ideal membrane would facilitate cell attachment onto its surface, thereby helping to stabilize the blood clot and integrate the membrane into the tissue. However, currently available titanium mesh has millimeter-level pore sizes, which lead to soft tissue ingrowth through the pores. Therefore, the aim of this study was to investigate the fibroblast attachment and migration on different designs of novel titanium mesh with micrometer pore size for guided bone regeneration treatment. Six types of novel titanium mesh membrane and three groups of commercially available membranes were used in this study. Fibroblasts were isolated from 4-day-old green fluorescence protein rats and seeded onto membrane surfaces. At 24 h, the cells attached to the membrane surfaces were fixed and stained with DAPI. The blue-stained nuclei on membrane surfaces, and both upper and lower sides were counted. It was shown that different membrane materials, structure and design differ considerably in their capacity for cell attachment to the membrane surface. The novel membranes, especially mesh with 12 pores compared with mesh with multi-pores, allowed the fibroblast attachment on the membrane surface, but hindered the fibroblast migration through the pores into the lower side of the membrane, which is associated with the defect area in the clinical condition.

"Latar Belakang: Periodontitis merupakan salah satu kondisi periodontal yang dapat menyebabkan poket periodontal. Terdapat berbagai metode perawatan poket periodontal, salah satunya adalah Guided Tissue Regeneration. Penelitian mengenai persepsi dan preferensi Dokter Gigi Spesialis Periodonsia di Indonesia mengenai penggunaan membran GTRpada terapi regeneratif jaringan periodontal belum pernah dilakukan di Indonesia.
Tujuan: Mendapatkan persepsi dan preferensi dokter gigi spesialis periodonsia di Indonesia mengenai penggunaan membran GTR.
Metode: Penelitian deskriptif dengan pendekatan potong lintang menggunakan kuesioner kepada dokter gigi spesialis periodonsia di Indonesia.
Hasil: 93 responden melakukan bedah regeneratif GTR dengan mayoritas 1-3 bedah setiap bulan dengan indikasi 2-3 wall defect. GTR dilakukan menggunakan membran resorbable collagen karena memberikan hasil perawatan yang lebih baik dengan parameter keberhasilan pertumbuhan tulang secara radiografi dan persentase kesuksesan sebesar 75%. Alasan responden tidak melakukan GTR karena biaya cukup tinggi. Responden puas dan percaya diri dengan teknik GTR dan setuju penggunaan material dari hewan, manusia dan sintetis. Jumlah bedah regeneratif periodontal GTR oleh dokter gigi spesialis periodonsia di Indonesia dipengaruhi oleh lama praktik dan tidak dipengaruhi oleh domisili daerah praktik.
Kesimpulan: Terdapat perbedaan persepsi dan preferensi dokter gigi spesialis periodonsia di Indonesia dalam penggunaan teknik GTR pada terapi jaringan periodontal regeneratif dan terdapat perbedaan signifikan antara jumlah bedah regeneratif periodontal GTR oleh dokter gigi spesialis periodonsia dan lama praktik.

Background: Periodontitis is one of the periodontal conditions that can cause periodontal pockets. There are various methods of treating periodontal pockets, one of which is Guided Tissue Regeneration. Research on the perceptions and preferences of Periodontists in Indonesia regarding the use of GTR membranes in periodontal tissue regenerative therapy has never been conducted in Indonesia.
Objective: Obtain the perceptions and preferences of periodontists in Indonesia regarding the use of GTR membranes.
Methods: Descriptive study with a cross-sectional approach using a questionnaire to periodontists in Indonesia.
Results: 93 periodontists in Indonesia performed GTR with the majority of surgeries performed 1-3 times a month and indications of 2-3 wall defects. GTR is performed using a resorbable collagen membrane because it provides better treatment results with radiographic parameters of bone growth success and a treatment success rate of 75%. The reason respondents did not do the GTR was because the cost was quite high. Respondents were satisfied and confident with the GTR technique and agreed to use animal, human and synthetic materials. The number of GTR periodontal regenerative surgeries by periodontists in Indonesia is influenced by length of practice and not by domicile in the practice area.
Conclusion: There are differences in the perceptions and preferences of periodontists in Indonesia regarding the use of the GTR technique in regenerative periodontal tissue therapy and there are significant differences between the number of GTR regenerative periodontal surgeries by periodontists and the length of practice.

"ABSTRACT
To evaluate the degree of periodontal tissue destruction, aspartate aminotransferase (AST) levels in the gingival crevicular fluid (GCF) are utilized as a predictor of periodontal therapy. We have previously shown that the usefulness of AST activities [periodontal tissue monitor (PTM) values] using a PTM-kit to evaluate the effects of initial periodontal therapy and periodontal regeneration therapy by enamel matrix derivative (EMD). This prospective, longitudinal study was conducted using 38 healthy and 80 periodontitis sites with probing depth (PD) of 5 - 10 mm for guided tissue regeneration (GTR) and EMD from 36 patients. GCF samples were used to evaluate PTM values at base line (BL) and after 6 months of surgeries (re-evaluation: RE), and periodontal examinations were performed concurrently. PTM values at BL were statistically improved at RE, accompanied by the improvement of periodontal parameters in both groups. PTM values and PD, and the clinical attachment level (CAL) showed high correlations. PD, CAL and bleeding on probing (BOP) were highly correlated with PTM values in both groups, whereas only PD showed a significant correlation with PTM values at RE in the GTR group. Change in the amounts of PD, CAL and BOP between BL and RE in both groups showed no correlation with PTM values. In the negative PTM value sites at BL in EMD group, the mean PD was significantly reduced at RE compared with positive PTM sites at BL. PTM values are able to be utilized as the biochemical predictor of prognosis after periodontal regeneration therapy."

Terdapat perbedaan bermakna (p<0,01) antara jumlah sel osteoblas, jumlah sel radang dan angiogenesis terhadap interval waktu (3 hari, 7 hari, 10 hari, 14 hari dan 21 hari). Kesimpulan: Penggunaan komposit membran (PVA-Kolagen-Hidroksiapatit) mempercepat regenerasi tulang mandibular pada hewan coba tikus Sprague?Dawley.

ABSTRACT
Background: The need of alternative bone substance in oral and maxillofacial surgery has increased. Guided bone regeneration method (GBR) is one of bone adding volume method by making the bone tissue regeneration to occur selectively in a room where the growth of bone cells are protected by a particular substance (membrane). It has been known that the developing biocomposite substance is cannot be achieved from only a single substance to recover all the requirements needed in the use of biomedic implant. In this study, a composite membrane consist of combination of polivinilalcohol material (PVA) + collagen + hydroxyapatite was made. Composite membrane applied on the mandibular defect of Sprague-Dawley rats.
Objective: To evaluate the use of compocite membrane (PVA-Collagen-Hydroxyapatite) for regeneration of mandibular defect in animal testing (rats) comparing with group control of animal testing by observing the osteoblas, membrane (PVA-Collagen-HA) applied only in rats of testing group. The appearance of osteoblasts, inflammation cells, and angiogenesis were evaluated histopathologically on interval of 3rd, 7th, 10th, 14th and 21st day after application of composite membrane. Result: There are significant differences (p<0,01) in the number of osteoblast cells, inflammation cells and angiogenesis between the control group and the group applied with composite membrane (PVA-Collagen-Hydroxyapatite) on interval of determined days (day 3, day 7, day 10, day 14 and day 21st). Conclusion: Use of composite membrane (PVA-Collagen-Hydroxy) accelerates the mandibular bone regeneration of animal testing Sprague-Dawley rats.;Background: The need of alternative bone substance in oral and maxillofacial surgery has increased. There are many ways can be done to add bone volume.
