Abstract

Background: Forensic dentistry identification commonly involves using dental cast models as ante-mortem data. Here, dentists generally send the pictures as well as the dental records. However, in recent times, dentists – especially orthodontists and prosthodontists – are using 3D scanners in view of reducing the space for cast model storage as well as sending the 3D imaging for fabricating clear aligners and other items such as crowns and bridges. This new trend means data transmission and viewing has become more complicated since sophisticated laptops or personal computers are generally required. For more practical use, smartphones would be a better option, meaning various simple ideas for viewing 3D data must be explored. Furthermore, the conclusions must be evaluated in terms of the validity for forensic dentistry use. Purpose: To evaluate a number of smartphone applications that are simple, user friendly, scalable and capable of the measurement and superimposition of 3D imaging data. Review: Standard tessellation language (STL) is one of the 3D scan file formats that is also useful for 3D printing. Recently, several applications for 3D viewing have been made available for iPhones (iOS) and Android-based devices, which are able to view STL files. However, they have all received both positive and negative reviews in terms of various applications, including forensic dentistry, and they thus require further evaluation by forensic odontologists. Conclusion: Each application has advantages and disadvantages; however, in our experience as forensic odontologists, the CAD Assistant, exocad and Adobe Photoshop Mix, which are available for iOS and Android devices, are preferable for forensic dentistry needs

Abstract

Background: Maintaining a good ridge is required during prosthodontic treatment. Hence, adequate alveolar bone support is considered an important factor in pursuing successful dentures. Propolis extract combined with bovine bone graft is a recent and innovative material in the process of socket preservation, as the caffeic acid phenethyl ester (CAPE) it contains can suppress the inflammatory process. Purpose: This study aims to determine the effective dose of propolis extract combined with bovine bone graft on the number of osteoblasts and osteoclasts in socket preservation. Methods: Twenty-eight Cavia cobaya animals were divided into four groups of seven. Group I was given 25 grams of PEG, while Group II were given a propolis extract at a dose of 0.5% combined with bovine bone graft. Group III were given a propolis extract at a dose of 1% combined with bovine bone graft and Group IV were given a propolis extract at a dose of 2% combined with bovine bone graft. On day 30, the lower incisor of each subject was extracted and induced with PEG and propolis (dose 0.5%, 1%, 2%). Histopathological examinations of osteoblasts and osteoclasts were measured with a 400x magnification light microscope. One-way ANOVA and Tukey HSD tests were performed to analyse data statistically. Results: The propolis extract combined with bovine bone graft not only increased the number of osteoblasts but also reduced the number of osteoclasts. The most effective dose for the propolis extract combined with bovine bone graft was 2%. Conclusion: The propolis extract combined with bovine bone graft could be effective in tooth extraction socket preservation at a dose of 2%.

Abstract

Background: Propolis is a natural biocompatible material that has been widely studied in dentistry because of its inflammatory, anti-microbial and immunomodulatory properties. One of the active components is caffeic acid phenethyl ester (CAPE). CAPE is effective in stimulating collagen as well as inhibiting the inflammation and degeneration of dental pulp. Purpose: To investigate the post-administration of propolis extract as pulp capping material enhances odontoblast-like cell thickness and type 1 collagen expression in Wistar rats (Rattus Norvegicus) Methods: This research was a true experimental design with a posttest-only control group design. Sixty-three Wistar rats were randomly divided into three groups, with each group consisting of 21 rats: Group I: Positive control; no capping material was administered; Group II: CAPE was administered; Group III: 11% of the propolis extract was administered. All samples were filled with glass ionomer cement. Seven rats from each group were sacrificed after days 7, 14 and 28 of post-pulp capping administration, and their afflicted teeth were subsequently extracted for histologic analysis. Results: No significant difference was seen in odontoblast-like cell thickness after the application of CAPE and propolis on days 7 and 14 (p > 0.05). However, a significant difference was noticed on day 28 (p < 0.05), with the thickness of odontoblast-like cell in CAPE being thinner than that in propolis. A significant difference in the expression of type 1 collagen was observed on days 7, 14 and 28 after the application of the propolis extract compared with CAPE (p < 0.05). Conclusion: The post-administration of propolis extract as a pulp capping material could enhance odontoblast-like cell thickness and type 1 collagen expression in Wistar rats.

Abstract

Background: The normal vertical dimension of occlusion (VDO) results in orofacial and temporomandibular joint (TMJ) biomechanical balance. If the VDO changes due to attrition, full edentulism, accidents involving the lower third of the face and even improper denture manufacturing will result in the disruption of mastication, speech and aesthetic functions. Therefore, the right technique is needed to predict the correct VDO. Purpose: To identify the correlation values and regression equation of the VDO for five distances between facial landmarks among people of Batak Toba ethnicity. Methods: This research is an analytical study with a cross-sectional design. A purposive-sampling technique obtained 30 Batak Toba subjects, consisting of 15 males and 15 females aged 19–24 years. The data were analysed by an independent t-test, one-way ANOVA, the Pearson correlation, and linear regression (p<0.05). Results: A significant difference distance in the VDO (p=0.0001, p<0.05) was observed between male subjects (72.96±3.75mm) and female subjects (65.24±5.12mm). A positive and significant correlation was observed between the VDO distance and the facial landmark distances, where the criteria for significant correlation were the RO–Pu distance being {r male=0.723(p=0.02) and female=0.650(p=0.09)} and the OC–RO distance being {r male=0.689(p=0.004) and female=0.615(p=0.015)}; the moderate correlation criteria were the OC–IC distance being {r male=0.476(p=0.045) and female=0.428(p=0.043)}, the E–E being {r male=0.435(p=0.043) and female=0.458(p=0.047)}, and the EH being {r male=0.398(p=0.051) and female=0.414(p=0.051)}. The regression equation for the VDO distance in males is {[22.694 + 0.673 (RO–Pu)], [24.371 + 0.642 (OC–RO} and in females is {[23.017 + 0.616 (RO–Pu)], [21.795 + 0.632 (OC–RO)]}. Conclusion: The distances of RO–Pu and OC–RO have the strongest correlation with the VDO in people of Batak Toba ethnicity.

Abstract

Background: Acid etching is a stage in obtaining bonds between composites and enamel. The application of acid to the enamel surface, however, can cause dissolution of hydroxyapatite and demineralisation of the enamel surface. Phosphoric acid, a strong acid, is an etching material that can reduce enamel hardness. Excessively reducing hardness can interfere with attachment to the restorative material. One medicinal plant that can be used as an alternative material in acid etching is tamarind. Purpose: This study aims to determine the effect of 5% tamarind extract gel on the tensile strength of composite resins. Methods: This is an experimental research study with a post-test-only control-group design. The study used 14 mandibular incisors. The labial part of the incisor was prepared using a diamond fissure bur with a diameter of 4 mm and a depth of 2 mm. The control group was then etched with 37% phosphoric acid gel, while the experimental group was etched with 5% tamarind extract gel. Bonding resins and micro-hybrid composite resins were applied, based on the manufacturers’ instructions. Next, a tensile strength test and seeing formation resin tags by scanning electron microscope (SEM) were performed. Data were analysed using an independent t-test (p < 0.05). Results: The average tensile strength of composite resins in the group etched with 5% tamarind extract gel was the same as in the 37% phosphoric acid group (p > 0.05). SEM images also show that enamel etched with 5% tamarind extract gel produced a tag similar to that etched with 37% phosphoric acid gel. Conclusion: 5% tamarind extract as an etching material can generate tensile strength of composite resin and trigger formation of resin tags in the same way as 37% phosphoric acid.

Abstract

Background: Post-extraction alveolar bone height and width never reach the same dimensions as before extraction. A combination of propolis extracts and bovine bone graft (BBG) that are anti-inflammatory, antioxidant, osteoinductive and osteconductive is expected to improve bone regeneration. Purpose: Knowing the effect of the combination of propolis extracts and BBG on the number of osteoclast and osteoblast as an effort to preserve the socket after extraction of Cavia cobaya teeth. Methods: 56 Cavia cobaya was divided into eight groups: the lower left incisor was extracted, and the socket was filled with 2% poly ethylene glycol (PEG), propolis extract+PEG, BBG+PEG, and a combination of propolis extract+BBG+PEG. The incisors socket of animals models were executed on the 14th and 30th days. Using HE for histopathological examination, the number of osteoclasts and osteoblasts were counted with a 400x magnification light microscope with nine visual fields. The data were analysed via one-way ANOVA and Tukey HSD tests. Results: The highest mean number of osteoclasts occurred in the BBG+PEG 14th day group and the lowest occurred in the propolis extract+BBG+PEG 14th day group. The highest mean number of osteoblasts occurred in the propolis + BBG + PEG combination 30th day group, the lowest occurred in the control group (PEG) on the 14th day. Conclusion: The 2% combination of propolis extracts and BBG effectively reduces the osteoclast number and increases the osteoblast number in preserving the socket after extracting Cavia cobaya teeth.

Abstract

Background: Pophyromonas gingivalis (P. gingivalis) bacteria are the main type of bacterium that cause chronic periodontitis. Immunoglobulin Y (IgY) is a type of immunoglobulin found in poultry, such as chickens and birds. IgY can be used as an alternative method of preventing the accumulation of plaque that causes chronic periodontitis. Purpose: To determine the ability of IgY anti P. gingivalis to inhibit adherence of P. gingivalis. Methods: The samples were divided into eight groups, each group containing 10 ml of IgY anti P. gingivalis and 50 ml of enterocyte cells. The control group contained 50 ml of IgY anti P. gingivalis, and 50 ml of enterocyte cells. Serial dilution was carried out to the first seven groups, with the first group containing 90 ml phosphate-buffered saline (PBS) and 10 ml IgY anti P. gingivalis, and the second to seventh groups containing 50 ml PBS before adding 50 ml of enterocyte cells and 50 ml of bacterial suspension per group. The number of bacteria was calculated as an adherence index value using a light microscope. Results: This study shows that IgY anti P. gingivalis significantly reduces the adherence index value of P. gingivalis. Conclusion: IgY anti P. gingivalis has potency to inhibit the adherence of P. gingivalis.

Abstract

Background: The prevalence of dental caries is high worldwide and specifically in Indonesia, especially in children. Cariogenic bacteria are the major cause of dental caries. Streptococcus mutans (S. mutans) is one of the bacteria often associated with caries, due to its ability in producing acid and forming the biofilm for bacterial colonisation on the surface of oral cavities. In addition to S. mutans, Streptococcus sobrinus (S. sobrinus) bacteria are also thought to play an important role in the process of caries. Purpose: This study aims to analyse the distribution of S. mutans and S. sobrinus in children with seriously high dental caries levels. Methods: This study was an observational analytical study. Bacterial isolation was conducted in carious lesions of 50 paediatric patients 6-12 years old with superficial dental caries. Samples of caries lesions were put directly into a tube containing the Brain Heart Infusion Broth (BHI-B) and incubated at 37o C for 24 hours. The samples were sub-cultured on selective tryptone yeast cystine sucrose bacitracin (TYCSBHimedia) agar, and then incubated for two days. Bacterial identification was then performed using the polymerase chain reaction (PCR) Multiplex method. Statistical analysis with Chi-square. Results: The total number of children with dental caries included in this study was 50. Among these, 94% showed positive for S. mutans and 30% positive for S. sobrinus. The analysis of the prevalence of bacterial colonisation (S. mutans and S. sobrinus) based on caries severity and the Simplified Oral Hygiene Index (OHI-S), showed there was no significant difference (p> 0.05). Conclusion: This study showed that among 50 caries noted in the children, 94% were colonised S. mutans and 30% S. sobrinus. There was no significant difference between the colonisation of S. mutans and S. sobrinus among children from the severe to mild decayed exfoliated filling teeth (DEFT) category, and between bad and good OHI-S.

Abstract

Background: Periodontal surgery forms a part of periodontal treatment that can sometimes cause open wounds, such as gingivectomy and depigmentation. Unfortunately, the healing process of open wounds can be inhibited due to bacterial infections and systemic factors. Thus, after surgery, the open wounds need to be closed with periodontal dressing. Purpose: This study aims to reveal the differences between using zinc oxide non-eugenol and cellulose periodontal dressings on open wounds after periodontal surgery. Methods: Thirty-two samples were divided into two groups. Group I consisted of 16 samples where zinc oxide non-eugenol was applied as a periodontal dressing. Similarly, Group II consisted of 16 samples where cellulose was applied as a periodontal dressing. The dressings were applied to open wounds after periodontal surgery using the split-mouth technique. Hence, zinc oxide non-eugenol was applied on the right side and cellulose was applied on the left side of the mouth. The patients’ healing index (HI) score was measured on day seven and their wound healing index (WHI) score was measured on days seven and twenty-one. Results: The day-seven HI score of the wounds applied with cellulose was higher than those applied with zinc oxide non-eugenol. Meanwhile, the WHI of the cellulose group was lower than that of the zinc oxide non-eugenol group, except on day twenty-one. Both the HI and WHI scores then were analysed using Mann Whitney. Conclusion: The application of cellulose is better than zinc oxide non-eugenol on the healing of open wounds after periodontal surgery.

Abstract

Background: A composite resin is used as restorative material in dentistry because it has the same colour as dental enamel, is easy to use in an oral cavity and offers good biocompatibility. Based on the size of filler, composite resin is divided into types, one of which is a composite resin nanohybrid. An important mechanical property of restorative material is microhardness. The mechanical properties of restorative material is highly affected by both polymerisation and heating process. There are many methods to improve composite resin’s microhardness, including preheating and heat treatment. Purpose: The purpose of this study was to evaluate different effects of preheating and heat treatment on the microhardness of nanohybrid composite resin. Methods: This study is an experimental laboratory research with post-test-only group design. Samples were divided into six groups: preheating groups at temperatures of 37oC and 60oC, heat treatment groups at temperatures of 120oC and 170oC, a negative control group and a positive control group. Afterwards, the resulting data were analysed using one-way ANOVA. Results: The result based on the one-way ANOVA test indicated that there was a difference in microhardness in each group with a significance of 0.000 (p<0.005) between preheating and heat treatment. Conclusion: The conclusion of this study was the best microhardness of composite resin nanohybrid is the heat treatment group at temperature 170oC.
