Abstract

Background: Color evaluation is crucial to evaluate a material’s quality. One alternative method for evaluating material’s color is using photographs analysed by software. This research evaluates the use of digital imaging and software (ImageJ and Photoshop) to obtain color differences of tooth sample in-vitro. Method: The sample used is bovine teeth that were given tea-staining and brushing treatment using five tested toothpastes. Sample’s photographs for each toothpaste’s group (n=4) were taken before and after experiment. DLSR Nikon D90 was used with digital CCD censor, macro lens 105mm, manual setting (ISO 200, F-Stop 5, Shutter Speed 1/400) with distance to sample of 25cm. Sample was positioned in foldable mini-studio-box (24.5x24.5x22.5cm) with LED-lighting (6500-7000 color temperature). The photographs were taken in close room at 11.00am. Two software were used to obtain the color value from pre- and post-experimental photographs of the sample at the middle-third of the sample using CIE-Lab (Commision Internacional de l’Eclairage L*a*b) color system. The resulted color difference (ΔE) value of sample from the two-software were compared using independent T-test and evaluate the measurement accuracy using Pearson’s correlation (α=0.05). Result: ImageJ and Photoshop analyses of the sample photographs yield comparable ΔE values, as determined by an independent T-test (p=0.893). The Pearson correlation test reveals a positive correlation (R=0.904) between the two software. Conclusion: The use of digital photography and software to obtain ΔE values are accurate, representative, and recommended when taking into account the controlled procedure of photographing the sample and analysing the sample's color value.

Abstract

Gingivitis is the second most common disease that occurs in the oral cavity. The use of chlorhexidine as a gingivitis therapy agent has some side effects such as allergic reactions and bacterial resistance. Jasminum Sambac (L.) Aiton leaf nano-extract contains flavonoids, saponins, and tannins compounds reported to have an influence on wound healing process. The aim of this research was to determine the effect of observation time and concentrations of Jasminum sambac (L.) Aiton leaf nano-extract on the number of neutrophils, macrophages, and angiogenesis in the treatment of gingivitis-induced Sprague Dawley rats. Sixty male Sprague Dawley rats aged 2.5-3 months with body weight of 200-250 g were anesthetized with ketamine HCl (10 mg/kg BW) and xylazine (2 mg/kg BW) then induced using silk ligature 3.0 on the interdental of the mandibular incisor. The rats were divided into five groups and got daily spray using distilled water (negative control), nano-extract at a concentration of 40%, 45%, 50%, and 0.12% chlorhexidine (positive control). The rats were euthanized on the 1st, 3rd, 5th, and 7th days post-treatment. The tissues were processed histologically with HE staining. The number of neutrophils, macrophages, and angiogenesis were counted using a microscope (400x) and OptiLab Viewer® (13x) at five fields of view. The result of the Two Way ANOVA test showed that there were significant effect of concentrations and observation time, and interaction of both observation time and concentrations on the number of neutrophils, macrophages, and angiogenesis (p < 0.05). It can be concluded that observation time and concentrations of Jasminum sambac (L.) Aiton leaf nano-extract affected the number of neutrophils, macrophage, and angiogenesis in the treatment of gingivitis-induced Sprague Dawley rat (p < 0.05).

Abstract

Saat ini, gigi tiruan khususnya gigi tiruan lengkap (GTL) umumnya dibuat dengan cara konvensional, yakni dengan proses polimerisasi berbasis heat curing pada material poly(methyl methacrylate) atau PMMA. Kekurangan dari metode konvensional ini terletak pada rendahnya akurasi produk yang dihasilkan, proses yang relatif lama serta kenyamanan gigi tiruan saat digunakan. Salah satu teknik yang berpeluang digunakan dalam pembuatan gigi tiruan adalah teknologi additive manufacturing (AM). Meski demikian, metode baru ini masih perlu diteliti secara mendalam untuk meyakinkan bahwa teknik ini dapat digunakan untuk membuat gigi palsu. Salah satu hal yang masih perlu dikaji tentang teknik AM untuk gigi palsu ini adalah aspek kekuatan material yang diperoleh dengan teknologi ini. Pada penelitian ini dilakukan pengujian tekan material PMMA yang dicetak dengan metode AM dan heat curing konvensional. Pengujian dilakukan setelah material tersebut direndam dalam larutan air ludah atau saliva buatan. Hasil dari penelitian ini menunjukkan bahwa material yang dibuat dengan menggunakan metode AM memiliki kuat tekan yang lebih tinggi daripada material yang dibuat secara konvensional. Nilai kuat tekan tertinggi diperoleh pada material yang dicetak AM sebesar 130 MPa.

Abstract

Introduction: Tea consumption causes extrinsic stain formation on teeth and denture surfaces, affecting personal appearance. Herbal plants extract such as green tea, bay leaf, and lime peel are potentially active agents for extrinsic stain removal. This study aimed to analyse the effectiveness of green tea, bay leaf, and lime peel extracts as toothpaste active agents for extrinsic stain removal on teeth, artificial teeth, and denture base. Methods: Twenty-five post-extracted human permanent central incisors, 25 artificial teeth, and 25 heat polymerised acrylic resin denture base (20x20x10mm) were divided into three treatment groups and two control groups. Pictures of all specimens were taken before and after stain induction and after brushing. All specimens were immersed in a tea solution made from 2 grams of tea and 100ml of 100°C boiled water to induce extrinsic stain. The immersion process was repeated every 24 hours for seven days. All specimens were then brushed using an automatic toothbrushing machine for 70 seconds on each surface, 200 grams loads, and five speeds/second. Toothpaste used for brushing were three different active agent toothpaste (treatment groups), no active agent toothpaste, and commercial whitening (control groups). Colour index analysis of the specimen pictures computerised by CIELAB method. The data were analysed by one-way ANOVA (α=0.05). Results: Green tea, bay leaf, and lime peel extract toothpaste and positive control had higher L-values of extrinsic stain removal than essential toothpaste on all specimens. There was a significant difference between green tea, bay leaf, and lime peel extract toothpaste and negative control toothpaste (p<0.05), while no significant difference was found when compared to the positive control toothpaste (p>0.05). Conclusion: Green tea, bay leaf, and lime peel extract toothpaste are effective as extrinsic stain removal on teeth and acrylic resin denture base because of abrasive materials that work together with the active agents such as epigallocatechin-3-gallate (EGCG) in green tea, eugenol in bay leaf, and naringin in lime peel.
