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.

"Periodontitis is a multifactorial disease associated with genetic and environmental factors. Single-nucleotide polymorphisms (SNPs) are associated with susceptibility to common diseases such as diabetes and periodontitis. Although the oral cavity is exposed to various organisms, the conditions are well controlled by innate and acquired immune systems. Antimicrobial peptides (AMPs) play an important role in the innate immune system; however, the association of AMP-SNPs with periodontitis has not been fully elucidated. This study investigated the relationship between AMP-SNPs and periodontitis in Japanese. One hundred and five Japanese subjects were recruited, which included patients with aggressive, severe, moderate and mild periodontitis, and age-matched healthy controls. Genomic DNA was isolated from peripheral blood and genotypes of SNPs of β-defensin-1 and lactoferrin genes (DEFB1: rs1799946, rs1800972 and rs11362; and LTF: rs1126478) were investigated using the PCR-Invader assay. Protein level of AMPs in gingival crevicular fluid (GCF) was quantified by ELISA. Case–control studies revealed that the −44 CC genotype of DEFB1 (rs1800972) was associated with periodontitis (OR 2.51), particularly with severe chronic periodontitis (OR 4.15) and with combined severe and moderate chronic periodontitis (OR 4.04). No statistical differences were found in other genotypes. The β-defensin-1 concentrations in GCF were significantly lower in subjects with the −44 CC genotype of DEFB1 than in those without this genotype. No significant differences between GCF concentrations of AMPs and other genotypes were detected. The −44 CC genotype of the β-defensin-1 gene (DEFB1 rs1800972) may be associated with susceptibility to chronic periodontitis in Japanese."

"Periodontitis adalah penyakit inflamasi kronis yang mempengaruhi jaringan pendukung gigi dan memerlukan penanganan yang efektif untuk mencegah kerusakan lebih lanjut. Salah satu metode yang potensial adalah penggunaan local drug delivery film kitosan dengan penambahan glutaraldehid sebagai agen crosslinking untuk meningkatkan sifat mekaniknya. Penelitian ini bertujuan untuk mengevaluasi pengaruh durasi perlakuan uap glutaraldehid terhadap sifat mekanik dan perilaku swelling film kitosan. Film kitosan diproduksi menggunakan metode solvent casting dengan komposisi 1% propolis dan gliserin sebagai plasticizer, kemudian dilakukan crosslinking dengan larutan glutaraldehid 0,5% pada suhu 37°C dengan variasi waktu perlakuan 12 jam, 24 jam, dan 48 jam. Karakterisasi film dilakukan menggunakan Fourier Transform InfraRed (FTIR), Scanning Electron Microscope (SEM), analisis swelling, dan uji tarik. Interaksi kimia antara kitosan dan glutaraldehid ditunjukkan dengan puncak dan shoulder peak pada 1651 cm-1 dalam FTIR, mengindikasikan pembentukan ikatan imina (Schiff base) yang mempengaruhi sifat mekanik dan stabilitas film serta menandakan proses crosslinking berhasil dilakukan. Hasil penelitian swelling menunjukkan peningkatan waktu crosslinking mengurangi derajat swelling film hingga 80,27%, dengan film yang diberi perlakuan glutaraldehid menunjukkan derajat swelling lebih rendah (17,50-12,12%) dibandingkan film tanpa perlakuan. Waktu crosslinking juga meningkatkan sifat mekanik film, dengan kekuatan dan kekakuan meningkat hingga 662,3% (566,7 MPa) pada 12 jam, 725,1% (620,3 MPa) pada 24 jam, dan 1061,2% (907,9 MPa) pada 48 jam, dibandingkan film tanpa glutaraldehid (85,6 MPa). Dengan demikian, durasi perlakuan glutaraldehid optimal untuk film kitosan dalam aplikasi penyembuhan periodontitis adalah 12 jam. Durasi ini menghasilkan film kitosan dengan derajat crosslinking yang optimal, derajat swelling terkontrol, dan peningkatan sifat mekanik yang signifikan, memungkinkan film mudah disisipkan ke dalam kantong periodontal dan memberikan penghantaran obat yang efektif tanpa menyebabkan ketidaknyamanan yang signifikan akibat pembengkakan.

Periodontitis is a chronic inflammatory disease affecting the supporting tissues of teeth, requiring effective intervention to prevent further damage. One potential method is the use of local drug delivery chitosan films with the addition of glutaraldehyde as a crosslinking agent to enhance their mechanical properties. This study aims to evaluate the influence of glutaraldehyde vapor treatment duration on the mechanical properties and swelling behaviour of chitosan films. Chitosan films were produced using the solvent casting method with a composition of 1% propolis and glycerine as a plasticizer, followed by crosslinking with 0.5% glutaraldehyde solution at 37°C with treatment durations of 12 hours, 24 hours, and 48 hours. The characterization of the films was conducted using Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscope (SEM), swelling analysis, and tensile testing. Chemical interactions between chitosan and glutaraldehyde were indicated by peaks and shoulder peaks at 1651 cm-1 in the FTIR analysis, suggesting the formation of imine bonds (Schiff base), which affect the mechanical properties and stability of the film, indicating successful crosslinking. The swelling results showed that increasing the crosslinking duration reduced the swelling degree of the film by up to 80.27%, with glutaraldehyde-treated films showing a lower swelling degree (17.50-12.12%) compared to untreated films. Crosslinking time also enhanced the mechanical properties of the film, with strength and stiffness increasing up to 662.3% (566.7 MPa) at 12 hours, 725.1% (620.3 MPa) at 24 hours, and 1061.2% (907.9 MPa) at 48 hours, compared to untreated chitosan films (85.6 MPa). Thus, the optimal glutaraldehyde treatment duration for chitosan films in periodontitis treatment applications is 12 hours. This duration produces chitosan films with optimal crosslinking, controlled swelling, and significant improvements in mechanical properties, allowing the film to be easily inserted into periodontal pockets and provid."
