Abstract

Introduction: Shade selection in aesthetic dental procedures remains a challenge in dentistry. This challenge arises due to the high complexity of natural tooth color. The use of a shade guide as a form of communication between dentists and dental technicians is highly subjective, leading to the emergence of digital methods that offer a higher level of accuracy and consistency. The purpose of this research is to assess the type, brand, and price as preference of shade matching tools for dentists in Jakarta’s dental sector. Methods: The survey was conducted as a descriptive observational study using cluster sampling through questionnaires and a review of shade matching product catalogs from 30 dental suppliers, 4 dental clinics, and 7 dental laboratories in Jakarta. Results: There is a variety in the price and availability of shade matching products sold by dental suppliers in Jakarta, with VITA branded products dominating the market, including VITAPAN Classical (25%), VITA Classical (15%), VITA 3D Master (12%), and Ivoclar Vivadent (12%). In both clinics and dental laboratories, all respondents reported using visual methods, with VITA Classical and VITA 3D Master being the most commonly used products. Conclusion: Shade matching products available from dental suppliers, as well as their use in clinics and laboratories in Jakarta, are predominantly based on visual methods, with VITA Classical and VITA 3D Master being the most preferred shade guides. Digital shade matching methods are rarely encountered, mainly due to product complexity, cost, distribution limitations, and lack of training.Ketersediaan, tipe, merk, dan harga sebagai preferensi alat pencocokan warna oleh dokter gigi di sektor kedokteran gigi jakarta: survei potong lintangPendahuluan: Pemilihan warna dalam prosedur estetika menjadi tantangan dalam kedokteran gigi. Tantangan ini muncul karena warna alami gigi memiliki kompleksitas yang tinggi. Penggunaan shade guide sebagai bentuk komunikasi antara dokter gigi maupun teknisi laboratorium bersifat sangat subjektif sehingga muncul metode digital yang menawarkan tingkat akurasi dan konsistensi yang lebih tinggi. Tujuan penelitian ini adalah untuk mengevaluasi jenis, merek, dan harga sebagai preferensi alat pemilihan warna bagi dokter gigi di Jakarta. Metode: Survei dilakukan sebagai penelitian observasional deskriptif menggunakan sampling klaster dengan mengajukan pertanyaan serta penelahaan katalog produk shade matching pada 30 dental supplier, 4 klinik gigi, dan 7 laboratorium gigi yang ada di Jakarta. Hasil: Terdapat berbagai variasi dalam harga dan ketersediaan produk shade matching yang di jual dental supplier di Jakarta, dengan dominasi produk bermerek VITA, yaitu VITAPAN Classic (25%), VITA classical (15%), VITA 3D Master (12%) dan Ivoclar Vivadent (12%). Pada klinik dan laboratorium gigi didapatkan hasil bahwa seluruhnya menggunakan metode visual dengan produk yang paling banyak digunakan yaitu VITA Classical (27%) dan 3D Master (36%). Simpulan: Produk shade matching yang tersedia di dental supplier serta penggunaannya di klinik dan laboratorium Jakarta didominasi metode visual dengan VITA Classical dan 3D Master menjadi shade guide yang paling digemari. Metode pencocokan warna dengan metode digital jarang ditemui disebabkan kompleksitas produk, kendala harga, distribusi, dan kurangnya pelatihan.

Abstract

Bone cement is a filling material for bone defects consisting of a mixture of powdered biomaterials and a liquid so that it will harden in the body. The bone cement must be biocompatible, osteoconductive, osteoinductive, having good mechanical properties, and filling bone defects. Several studies have stated that good bone cement is bone cement with an optimal setting time. The setting time of bone cement is related to minimally invasive treatment. This article reviews the optimal setting time of several biomaterials that are often used in both medicine and dentistry.

Abstract

Abstract: Cassava peel and leaves (Manihot esculenta Crantz) are agro-waste materials rich in secondary metabolites with potential antimicrobial properties. Research exploring their effects against oral pathogens remains limited. This study aimed to evaluate the antibacterial and antifungal activity of cassava peel and leaf extracts against Staphylococcus aureus, Streptococcus mutans, and Candida albicans. This was a laboratory and experimental study. Samples of cassava leaves, outer and inner young peel (six months), outer and inner mature peel (10 months) were dried, powdered, and subjected to ethanol maceration. Phytochemical screening assessed flavonoids, alkaloids, saponins, tannins, quinones, steroids, and triterpenoids. Antimicrobial activity was tested using the microdiffusion well method, and inhibition zones were measured in millimeters. Positive controls were chloramphenicol (for bacteria) and nystatin (for fungi). Negative control was sterile aquadest. The results showed that leaf extract produced inhibition zones of 8.90 mm (S. aureus), 6.00 mm (S. mutans and C. albicans). Peel extracts showed varying activity, with outer young peel (6 months) yielding 7.25 mm (S. aureus), 6 mm (S. mutans and C. albicans)  and inner young peel (6 months) yielding 8.74 mm (S. aureus), 35.27 mm (S. mutans), 6 mm (C. albicans)  while outer mature peel (10 months) yielding 6.13 mm (S. aureus), 6.00 mm (S. mutans and C. albicans) and inner mature peel (10 months) yielding 10.44 mm (S. aureus), 55.36 mm (S. mutans), 6 mm (C. albicans). Phytochemical screening confirmed the presence of flavonoids, tannins, and saponins in most of cassava peel and leave samples. In conclusion, cassava peel and leaf extracts exhibit antimicrobial activity against major oral pathogens, with inner mature peels (10 months) showing the strongest effect against Streptococcus mutans. These results support their potential use as natural antimicrobial agents in herbal oral care formulations. Keywords: antibacterial; cassava peel; cassava leaves; oral pathogens; phytochemicals

Abstract

Introduction: Polymethylmethacrylate (PMMA) and thermoplastic nylon are materials used for making denture bases. Denture users use various methods in order to keep clean their denture. Mouthwash can be an option for cleaning dentures because it is easier to find. Objective: The objective of this research was to investigate the effect of mouthwash containing alcohol as a denture cleanser on flexural strength of polymethylmethacrylate and thermoplastic nylon. Methods: Eighteen samples of polymethylmethacrylate and eighteen samples of thermoplastic nylon with a bar shape (65x10x3 mm) are being used in this research. Each materials are randomly divided into 3 groups (n=6) so there will be six research groups incuded : (A1) PMMA immersed aquades, (A2) PMMA immersed in mouthwash containing alcohol 21.6%, (A3) PMMA immersed in mouthwash containing alcohol 9%, (B1) thermoplastic nylon immersed in aquades, (B2) thermoplastic nylon immersed in mouthwash containing alcohol 21.6%, (B3) thermoplastic nylon immersed in mouthwash containing alcohol 9%. Flexural strength of two materials was tested using universal testing machine (Shimadzu AGS - 5KNX, Japan). All of the data obtained were analyzed using two way Anova test. Result: The mean of flexural strength for group A1 (104.275 ± 15.469 MPa), A2 (103.298 ± 10.387 MPa), A3 (111.626 ± 14.957 MPa), B1 (42.707 ± 4.857 MPa), B2 (38.258 ± 3.246 MPa), and B3 (40.218 ± 1.542 MPa). Result of analysis showed that there was a significant differences between flexural strength of polymethylmethacrylate and thermoplastic nylon (p<0,05), but immersion in mouthwash containing alcohol showed no significant difference (p>0,05). Conclusion: This research found that flexural strength of polymethylmethacrylate higher than flexural strength of thermoplastic nylon and mouthwash containing alcohol can be an alternative for cleaning a denture because it does not affect the flexural strength of both material significantly.

Abstract

Introduction: Dental caries is a prevalent oral disease resulting from enamel demineralization caused by acidogenic bacterial activity. Toothpaste plays an important role in caries prevention through a combination of ingredients such as calcium carbonate, sorbitol, glycerin, gum arabic, sodium carboxymethyl cellulose, sodium fluoride, citric acid, and peppermint oil. This study aimed to evaluate the physicochemical properties of an experimental toothpaste base formulation. Material and Methods: This study employed a laboratory-based experimental design with a descriptive observational approach. The physicochemical properties, including pH, viscosity, and homogeneity, were evaluated on a toothpaste base formulation and compared with a commercially available toothpaste. Results and Discussion: Both the toothpaste base formulation and the commercial toothpaste exhibited pH values within the range of 7.80–7.85, meeting the requirements of the Indonesian National Standard (SNI). The toothpaste base formulation demonstrated a substantially lower viscosity (56.232 cP)  compared to the commercial toothpaste (182.872 cP). Differences in viscosity may be attributed to variations in formulation composition and thickening agents. Homogeneity testing confirmed that both formulations were physically homogeneous, indicating uniform distribution of ingredients and acceptable physical stability. Conclusion: The toothpaste base formulation met the evaluated physical parameters and exhibited characteristics comparable to those of a commercial toothpaste. Although its viscosity was lower than that of the commercial product, it remained within the range commonly reported for toothpaste formulations. Further optimization of the formulation, particularly its rheological properties, is warranted to improve product performance and consumer acceptability.

Abstract

Background: The dimensional stability of alginate impression material is very important for obtaining an accurate cast. Seal bag storage is one way to maintain dimensional stability of the impression material. Objectives: This research aims to compare the dimensional stability of alginate impressions between imprESSIX Color Change (Alginate A), Algeniux Normal Set Major (Alginate B), and Aroma Fine Plus Normal Set (Alginate C). The alginate impressions were stored in seal bags for 0 min, 10 min, 3h, 24h, 72h, 120h, and 168h. Method: Sixty-three gypsum cast samples were obtained from a master die using 3 different alginate impression materials.  The alginate impressions were stored in separate seal bags for each of the seven different time intervals, then the samples were poured with gypsum type III.  The buccal cusp length from right first molar to left first molar was measured for each gypsum cast sample using calipers and compared with the master die. The data were analyzed with two-way ANOVA followed by post hoc LSD test. Results: The distance between the mesial buccal cusps of the right and left first molar was 52.280 mm for the master die.  Gypsum cast samples of alginate A and B showed shorter lengths compared to master die, but the difference was not significant (p>0.05). A significant difference in dimensional stability was observed for alginate C (p<0.05) after 120h (52.080 mm) and 168h (52.057 mm). Conclusion: Dimensional stability of alginate impression was influenced by alginate composition and seal bag storage time. Seal bag storage could hold the dimensional stability of alginate A and B up to 168h, but for alginate C, the stability only lasted for 72h.

Abstract

Background: Addition silicone is an elastomeric impression material used to obtain an accurate impression. Compatibility between impression material and gypsum will affect the surface quality of the resulting models. Types III and IV gypsum are very commonly used in dentistry to pour impressions and produce working models; despite this, there has been no further research regarding the differences between the two types in terms of compatibility with addition silicone impression materials. Objectives: To compare the compatibility of types III and IV gypsum with addition silicone impression materials.  Methods: Gypsum compatibility was assessed on the basis of its ability to reproduce lines of certain widths. Thirty samples were produced by impressing a stainless steel ruled block (in accordance with ANSI/ADA Specification No. 19) with addition silicone (independent variable) and then pouring in type III or IV gypsum (dependent variable). The samples were divided into two groups: in Group A, addition silicone was poured with type III gypsum; in Group B, addition silicone was poured with type IV gypsum. The lines from the stainless steel ruled block that formed in the gypsum samples were observed with a microscope at 10x magnification. Each line was then assessed with a score from 1 to 4, according to Morrow’s standardization, where a score of 1 indicates that the line was reproduced clearly and sharply over its entire 25 mm length, and a score of 4 indicates that the line is reproduced incompletely with roughness and/or blemishes. The data were analyzed using the Mann–Whitney U test. Results: Group B (addition silicone poured with type IV gypsum) produced more results rated as 1 (60% of the group’s samples) than Group A (only 46.67% of the group’s samples). Conclusion: On the basis of the number of scores rated as 1, type IV gypsum was more compatible than type III gypsum with addition silicone.

Abstract

Introduction: Hydroxyapatite is widely used in toothpaste formulations because of its biocompatibility and its role in supporting enamel remineralization; however, its direct antimicrobial activity against oral microorganisms remains unclear. This study aimed to    analyze the antimicrobial activity of hydroxyapatite toothpaste against Staphylococcus aureus and Candida albicans. Methods: An in vitro experimental study was conducted using the well diffusion method. The tested materials included hydroxyapatite toothpaste at concentrations of 1%, 3%, and 5%, sterile distilled water as a negative control, commercial toothpaste as a positive control, and chloramphenicol 100 ppm and nystatin 5,000 mg/L as comparator controls for S. aureus and C. albicans, respectively. Inhibition zones were measured after incubation for 24 hours at 37 °C. Results: Hydroxyapatite toothpaste at all tested concentrations did not produce inhibition zones against either Staphylococcus aureus or Candida albicans, whereas the comparator controls demonstrated clear inhibitory effects. Statistical analysis using the Kruskal-Wallis test revealed significant differences among treatment groups for Staphylocossus aureus (p = 0.0005) and Candida albicans (p = 0.028). Conclusion: Hydroxyapatite toothpaste did not demonstrate direct antimicrobial activity against Staphylococcus aureus and Candida albicans when assessed using the well diffusion method. These findings indicate that hydroxyapatite is not optimal as a sole antimicrobial agent and should be combined with other active ingredients to enhance antimicrobial effectiveness
