Objective: This study aims to determine the effect of robusta green coffee gel on the collagen density in Wistar rats. Material and Methods: The subjects were 45 Wistar rats, each wounded with a 3 mm punch biopsy in the mandibular incisor gingiva. The rats were then divided into 5 groups, namely the positive control group (Povidone-iodine 10%), negative control (gel base), and 3 treatment groups (10%, 20%, and 40% concentration of Robusta green coffee gel). The intervention was carried out twice a day. A total of 3 mice in each group were then sacrificed on the 5th and 10th days to see the collagen density using the Mallory Trichrome staining technique. Collagen density was observed using a microscope with 400x magnification in 5 fields of view. Kruskal Wallis test was used for data processing. Results: There was no difference in collagen density regardless of the coffee gel concentration at each observation time, with p&gt;0.05. Conclusion: There was no effect on the times of observation or dose concentration of robusta coffee gel on collagen density on gingival wound healing in Wistar rats.

Objective: C. albicans infection is the most common opportunistic infection in humans, and the prevalence of this infection has been increasing recently. Exploratory research on materials that have antifungal potential is urgently needed. One of the stages in the study is the use of experimental animal models. By various extrapolations, we designed models of oral candidiasis for men and women. This study aims to evaluate the infection after the treatment we provide, both microbiologically and histologically. Material and Methods: Our male and female rats lowered their immune systems with the corticosteroid methylprednisolone. The rats' drinking water was mixed with antibiotics to disrupt the balance of the oral cavity's normal flora. To facilitate C.albicans exposure and avoid loss of C.albicans, rats were previously injected with chlorpromazine HCL. Results: The microbiological evaluation showed that in male and female rat models, the number of fungal colonies on oral mucosal swab cultures was significantly higher at five and eight days after exposure to putrefactive control mice. Histological evaluation showed that in model rats, the number of hyphae that penetrated the dorsum of the tongue was higher than in control rats five days after exposure. Conclusion: In conclusion, the method we used is proven to produce oral candidiasis model rats, both male, and female

Objective: This study aimed to characterize the hydrophobicity of the functionalized scaffolds for bone tissue engineering applications in Dentistry. Materials and Methods: This experimental study was conducted in the Tissue Engineering Laboratory of The University of Sheffield. The scaffolds were polycaprolactone (PCL) and functionalized using heparin, divided into five groups of prepared electrospun scaffolds. i.e., 1) Fully coated heparin, 2) Random drops of heparin, 3) Organized drops of heparin, 4) Stamping-micropockets with heparin, 5) PCL scaffold only (Control). Hydrophobicity was characterized by measuring the contact angle of distilled water drops on the scaffolds. One-way ANOVA was used as a data analysis test, with p&lt;0.05. Result: The mean contact angle of each group was 63.33, 63.83, 63.33, 73.00, and 64.58, respectively. There was no group of scaffolds categorized as hydrophobics and no statistically significant difference among and within groups. Conclusion: The functionalized scaffolds were mostly un-hydrophobic, being a deliberation of their biocompatibility and role in bone tissue engineering application in dentistry.

Objective: To evaluate the knowledge, perceptions, and preferences of Indonesian periodontists and resident students regarding the use of bone transplants in periodontal regeneration treatment. Material and Methods: This is a cross-sectional descriptive study using questionnaires given to members of The Indonesian Society of Periodontology. Results: All respondents had various knowledge and preferences regarding using bone grafts in periodontal regenerative therapy. Oral hygiene and radiographic appearance are parameters that must be evaluated before regenerative procedures. The most widely chosen graft is the xenograft due to better results, biocompatibility, and bioactivity of the material. Cost is the main reason why the respondents do not use bone grafts. Bone grafts are often combined with the GTR and membrane techniques, and the granular form is the most frequently used form of graft. Bone grafts are often used in periodontitis cases with vertical bone loss followed by implant placement. Conclusion: Xenografts are the most widely used bone graft material in Indonesia. There was no statistically significant difference between the two groups' perceptions of using bone grafts in periodontal regenerative therapy. Respondents were more satisfied with using bone grafts than with other materials.

Objective: Orthognathic surgery is surgery on abnormalities of dentofacial that occur in the maxilla, mandible, or both. Determine measurement of the type of dentoskeletal abnormality in malocclusion using cephalometric analysis. Steiner analysis is used because it is considered that the Sela tursica-nasion-point A (SNA) angle, Sela tursica-nasion-point B (SNB) used to describe the relationship between the maxilla and the mandible. Material and Methods: The study involved 30 patients who underwent orthognathic surgery between April 2017 and April 2022 at Hasan Sadikin Hospital Bandung. Cephalometric radiography was utilized for assessment, employing the Steiner method to analyze various angles. Patient characteristics, including gender and age, were also observed. Parameters such as the average angle of SNA, SNB, and ANB were examined, alongside diagnoses, the number of corrected jaws, and the type of orthognathic surgery. Results: The findings indicated a predominance of male orthognathic surgery patients (63.3%), with the majority falling within the age range of 19 to 20 years (40%). Grade III malocclusion was the most prevalent diagnosis (96.7%), with double jaw correction being the most common procedure performed (90%). Bilateral sagittal split osteotomy was utilized in 93% of cases, followed by Le Fort I osteotomy in 96.7% of cases and chinplasty in 16.7% of patients. The average SNA, SNB and ANB was 83.8o, 90.6o, and -6.8o, respectively. Conclusion: The findings indicated a higher frequency of orthognathic surgery among patients diagnosed with class III malocclusion. Additionally, a notable proportion of patients underwent simultaneous orthognathic surgery on both the maxilla and mandible.

Objective: This literature review's objective is to identify feasible materials that can be 3D printed and is utilised to create removable dentures. The review includes an overview of the properties, advantages, and limitations of different 3D printing materials, including polymers, metals, resins, ceramics, and composites. Methods: In the era of digital dentistry, additive manufacturing, or 3D printing, is taking the place of subtractive manufacturing, or milling. For example, pre polymerised PMMA (polymethylmethacrylate) used for subtractive manufacturing leads to more wastage of material (block) compared to additive manufacturing. Traditionally 3D printing has its roots in rapid prototyping (RP), which the name is given to the rapid production of models using additive layer manufacturing. Result: The study showed that the addition of CNCs and AgNPs to the PMMA resin resulted in a significant improvement in the mechanical properties of the printed parts. The flexural strength of the composite resin increased by up to 31.6% with the addition of 0.1 wt% AgNPs and 1 wt% CNCs. The impact strength of the composite resin also increased by up to 24.2% with the addition of 0.1 wt% AgNPs and 1 wt% CNCs. The researchers attributed the improvement in mechanical properties to the synergistic effect of CNCs and AgNPs, which enhanced the interfacial adhesion between the polymer matrix and the reinforcement particles. Conclusion: Additive manufacturing describes technologies that can be used anywhere throughout the product life cycle from pre-production (i.e. rapid prototyping) to full scale production (also known as mass production).

Objective: This paper aims to report the outcome of the coronally advanced flap with and without connective tissue graft in the root coverage procedure. We intend to explain the importance of connective tissue graft in coronally advanced flap surgery. Methods: Two patients with gingival recession required surgical intervention to get root coverage and improve aesthetics. Both patients were treated with a coronally advanced flap. We combined the coronally advanced flap with a connective tissue graft for the first patient's maxillary left second incisor and canine; meanwhile, we only did the coronally advanced flap for the second patient's maxillary right canine and first premolar. Results: Surgical intervention was done for both patients with good results. For the first patient with a connective tissue graft, we noticed increased thickness on the keratinized gingiva and gained 1 mm of root coverage. Meanwhile, we got full root coverage for the second patient. In this article, a patient with a connective tissue graft was observed for six months, and a patient without a connective tissue graft was observed for two years. In both cases, we noticed stable and good results. Conclusions: Coronally advanced flap procedure can be a reliable treatent for root coverage in the tooth with gingival recession. An additional connective tissue graft combined with a coronally advanced flap can increase keratinized tissue thickness.
