“…Previously, we attempted to develop a tooth surface adulterant that reduces the SFEs of tooth and dental material surfaces, while offering acid resistance and prevention of adhesion, plaque generation, and deliming of the dentin. The adulterant was intended to prevent caries and gum disease (38). In the present study, however, viable bacterial counts changed when the SFE was less than 50 mN/m, regardless of the material used.…”

We used a polymicrobial (PM) biofilm model to examine associations of bacterial adhesiveness with surface characteristics of various dental materials. Four types of dental materials (apatite pellet, zirconia, ceramic, and composite resin) with rough and mirror surfaces were used. Surface roughness, surface free energy, zeta potential, and colony-forming units (CFUs) of the biofilm formations were measured. Biofilms were cultured for 24 h under anaerobic conditions, plated onto blood agar medium, and anaerobically cultured for 4 days. After culturing, CFU per mm 2 was calculated, and samples were observed under a scanning electron microscope. Means and standard deviations of the experimental data were estimated, and one-way ANOVA and Tukey multiple comparison assays were performed. Pearson correlation coefficients were obtained for the CFU and surface characteristics. Surface roughness and surface free energy appeared to affect generation of PM biofilms on oral materials, and zeta potential was involved in generation of PM biofilms on mirrorground oral materials.

Secara alamiah, bakteri rongga mulut mempunyai kecenderungan untuk melekat pada permukaan jaringan keras danlunak rongga mulut karena ketersediaan makanan untuk bakteri terakumulasi di permukaan. Kondisi patologis yangditimbulkan oleh perlekatan bakteri pada permukaan menjadi perhatian khusus dan menjadi objektif penelitian ini, yaituuntuk mencari metode yang efektif dalam menghambat perlekatan bakteri. Metode yang diteliti adalah metode pelapisanpermukaan/coating pada permukaan material restorasi RK yang bertujuan untuk memodifikasi sifat permukaan (surfacetreatment) material restorasi RK yang cenderung bersifat hidrofobik. Sifat hidrofobik ini ditengarai menjadi salah satufaktor penting yang berkontribusi terhadap perlekatan bakteri. Dengan melakukan modifikasi permukaan diharapkandapat mengurangi kemampuan perlekatan bakteri pada permukaan restorasi RK. Indikator yang digunakan untukmengamati perubahan sifat hidrofobisitas permukaan adalah perubahan sudut kontak (contact angle) cairan yangditeteskan pada permukaan. Sudut kontak permukaan yang lebih kecil mengindikasikan permukaan yang bersifat lebihhidrofilik. Untuk mengevaluasi efektivitas metode pelapisan pada permukaan yang bertujuan untuk memodifikasi sifatpermukaan, digunakan senyawa berbentuk cairan yang diekstrak dari buah mahkota dewa (phaleria macrocarpa (scheff.)boerl). Pengaruh permukaan yang dilapisi dengan cairan ekstraksi terhadap perlekatan bakteri diuji dengan menggunakanalat Scanning Electron Microscopy (SEM). Hasil penelitian menunjukkan metode pelapisan dengan cairan ekstrak buah mahkota dewa mampu menurunkan sifat hidrofobisitas permukaan RK, dan hasil gambaran SEM secara kualitatifmenunjukkan adanya penghambatan pembentukan koloni bakteri S.mutans. pada permukaan yang dilapisi dengan cairanekstrak buah mahkota dewa.

“…We have also studied their application for caries prevention and periodontal disease through the suppression of adhesion and plaque formation and decalcification of dentine. [10][11][12][13] Because the Japanese population is aging, development of an advanced surface modifier that not only prevents the adhesion and accumulation of plaque but also has antimicrobial activity is of urgent importance to actively kill the adhered microorganisms for the prevention of systemic complications. Quaternary ammonium salts, a class of commercially available antimicrobial agents sometimes referred to as invert soaps, display potent bactericidal and disinfecting effects with minimal irritation and low toxicity, and they are promising antimicrobial compounds because of their improved safety.…”

The purpose of this investigation was to evaluate the antimicrobial activity of a novel quaternary ammonium silane coupling agent, N-allyl-N-decyl-N-methyl-Ntrimethoxysilylpropylammonium iodide (10-I), against early stage biofilms using a polymicrobial biofilm model that simulates oral plaque-like biofilm formation on a solid phase. Cover glasses were immersed in a sufficient volume of the 800-ppm solution of 10-I for 1 h to modify the surface. Aliquots of a mixture of stimulated saliva from a single subject and McBain medium were dispensed into polystyrene 24-well cell culture plates and then cultured at 37.0°C under anaerobic condition. After culturing, we calculated colony forming unit (CFU). CFU of the 10-I group was approximately 80% lower than that of the control group, demonstrating strong antimicrobial activity. Therefore, surface modification with 10-I is effective for treating oral indigenous bacteria-related dental diseases found in the elderly and immunocompromised individuals and possible systemic complications, such as aspiration pneumonia.
