Enucleation of radicular cyst in the maxillary area
No full textRadicular cyst is a true cyst that develops in association with a root of non-vital teeth. Radicular cyst is the most common cyst in the oral cavity with a percentage of 50% of all cysts in the oral cavity. Radicular cysts are usually asymptomatic and may cause swelling, tenderness, or tooth mobility. Another problem is due to the neoplastic transformation of the epithelial lining; however, this case is very uncommon. Management of radicular cysts consists of endodontic treatment, apicectomy on the root of non-vital teeth or decompression by enucleation, and extraction of the related teeth.A 63-year-old female patient came to RSGM Prof. Soedomo with a complaint of swollen gums in the area of upper front teeth that had been present for approximately a year with no associated pain. The patient previously had a panoramic X-ray examination, and the result revealed a radicular cyst. Biopsy aspiration results showed that there were cholesterol crystal-filled cysts. There was no history of systemic disease. The patient was treated by enucleation of the radicular cyst followed by extraction of the related teeth using general anesthesia. The patient was periodically evaluated postoperatively. The wound healing process was evaluated as expected, and the patient's complaints reduced. Clinical examination accompanied by radiographic examination and biopsy aspiration showed the presence of a radicular cyst. Treatment options, including cyst enucleation, depended on several factors, such as an expansion of the lesion, size and association of the cyst with surrounding tissue, as well as the patient’s systemic condition. Irrigation and drainage of the bone cavity and curettage of the remaining tissue should be done to ensure the lesion has been removed completely. The remaining bone spicules were shaped and smoothed, and primary wound closure was performed in order to minimize recurrency and complication
The effect of oil palm empty fruit bunch (Elaeis guineensis Jacq.) fiber addition at various volume fractions on the compressive strength of flowable composite resin
No full textOil palm empty fruit bunch (OPEFB) fibers have emerged as a promising natural alternative to synthetic fibers due to their mechanical strength and biocompatibility, although research on their use as a reinforcing in composite resin remains limited. This study aimed to evaluate the effect of OPEFB fiber incorporation on the compressive strength of flowable composite resin. A true experimental design with a post-test-only control group was employed. The OPEFB fibers underwent chemical and double silane treatments and were randomly oriented prior to incorporation. Fifteen cylindrical specimens (6 mm × 12 mm) were allocated into three groups based on fiber volume fraction (0%, 1%, and 1.5%). Compressive strength was tested using a universal testing machine following ASTM D-695 standards. Data were analyzed using one-way ANOVA (p < 0.05) followed by a post-hoc Least Significant Difference (LSD) test. The mean compressive strength of flowable composite resins at 0%, 1%, and 1.5% OPEFB fiber volume fractions were 261.99 ± 17.64, 301.20 ± 19.26, 368.52 ± 14.90 MPa. One-way ANOVA test showed that the mean compressive strength in the three groups was significantly different (p < 0.05). The post-hoc LSD test showed significant differences (p < 0.05) among all groups. This study concluded that the incorporation of OPEFB fiber can enhance the compressive strength of flowable composite resin, with the highest reinforcement observed at the 1.5% OPEFB fiber volume fraction
Silkworm cocoon (Bombyx mori) accelerates wound healing in skin excision: a study on macrophage and VEGF
No full textSilkworm cocoon (Bombyx mori) is a natural polymer composite and largely used as bio-functional material for wound healing. It consists of fibroin and sericin protein that has antibacterial effect. This study aimed to investigate the effect of silkworm cocoons (Bombyx mori) wound dressing on the number of macrophages and VEGF expression in skin excision. The subject of this study was 12 Wistar rats, which were grouped based on the duration of wound dressing application (3rd day and 6th day) and the use of dressing materials (n = 6). The rats were anesthetized with ketamin and xylazine prior to wound excision. A punch biopsy wound excision with 4 mm diameter of subcutaneous depth was made on both sides of the rat’s back, with the right side dressed with silkworm cocoon as the treatment group and the left side dressed with moist gauze application as the control group. Hematoxylin-eosin (HE) staining was performed to observe the number of macrophage cells. Immunohistochemical staining using an anti-VEGF antibody was performed to observe the expression of VEGF. Data were analyzed using a two-way ANOVA and an Independent t-test with confidence interval of 95%. Statistical analysis demonstrated a significantly higher number of macrophages in the silkworm cocoon wound dressing group on 6 days post-application (p = 0.026) and significantly higher VEGF expression in the silkworm cocoon wound dressing group on 3 days post-application (p = 0.002) and on 6 days post-application (p = 0.044). Silkworm cocoon (Bombyx mori) wound dressing can increase the number of macrophages and VEGF expression in wound excision model in Wistar rat
Development of a surgical guide using open-source software for a dental implant placement
No full textDental technology has advanced significantly in recent years, particularly with regard to the placement of dental implants to replace lost teeth. One such technology is the use of a dental implant guide as a tool to assist with implant installation. The primary purpose of a dental implant guide is to assist the dentist in placing implants with accuracy and precision to maximize operation success and minimize risk of problems. Dental implant guides customized to each patient’s unique tooth and jaw architecture are made possible in large part by digital dentistry. To ensure that the implant is positioned optimally in relation to the patient’s teeth and jaw anatomy, customization is important. Using the AutoDesk meshmixer for modeling and manufacturing, a 3D slicer to segment the mandible using a 3D segmentation approach and 3D printing using resin and filament are all part of the dental implant guide design process. To improve precision and customization in the placement of dental implants, this comprehensive strategy makes use of digital dentistry
Effect of 10% lemongrass (Cymbopogon citratus) and 3% hydrogen peroxide solution immersion on the dimensional stability of alginate impression
No full textPathogenic bacteria can easily spread through impression materials, especially alginate. One of the chemicals disinfection agents used is hydrogen peroxide and natural disinfection alternatives, such as the decoction of lemongrass leaves. The aim of this study is to determine the effect of immersing Alginate impression in a disinfection solution of lemongrass (Cymbopogon citratus) and 3% hydrogen peroxide on the dimensional stability. The samples of this research consisted of 27 alginate impression samples of the upper jaw teeth prepared by manipulating alginate powder with water according to the manufacturer’s ratio and a lemongrass solution prepared by boiling 300 grams of lemongrass leaves 3000 ml of distilled water to obtain 300ml of lemongrass leaf decoction. The 27 samples were divided into three groups: the control group soaked in aquadest, one group soaked in 3% hydrogen peroxide, and one group soaked in 10% lemongrass decoction. The dimensional stability was measured by using a caliper for the horizontal dimension and then analyzed by using the Kruskal-Wallis test. This statistical analysis found a p-value of <0.05 in the horizontal dimension, indicating a difference in the horizontal dimensional stability of the alginate impression after immersion among the hydrogen peroxide, lemongrass leaves (C. citratus), and control groups. Further comparisons among the groups by using the Mann-Whitney Test resulted in a p-value of <0.05 for all the comparisons among the horizontal dimension of the groups. The dimensional changes of the alginate impression were slightly larger in the immersion of 10% lemongrass solution compared to the 3% hydrogen peroxide solution
The impact of varying concentrations of hyaluronic acid gel on the enhancement of VEGF and angiogenesis expression
No full textPeriodontal dressings can contribute to plaque accumulation, which in turn may cause inflammation, irritation of healing tissues, bacteremia, and difficulties in eating. Advances in knowledge and technology have improved the materials used in these dressings, aiming to enhance effectiveness and minimize complications. High-molecular-weight hyaluronic acid (HMW-HA) is a promising dressing material because of its anti-inflammatory properties and its ability to promote epithelial regeneration. This study aimed to determine whether different concentrations of HMW-HA gel influence vascular endothelial growth factor (VEGF) expression and angiogenesis during gingival wound healing in white rats (Rattus norvegicus) of the Wistar strain. A total of 42 rats were divided into seven groups: a negative control group (K1), a positive control group (K2) treated with 0.2% Gengigel®, and five treatment groups (P1–P5) receiving HMW-HA gel at concentrations of 0.2%, 0.4%, 0.6%, 0.8%, and 1%, respectively. Standardized 2 mm wounds were created with a punch biopsy on the lower anterior jaw of each rat. Treatments were administered twice daily for seven days. VEGF expression and angiogenesis were evaluated using immunohistochemical and hematoxylin–eosin staining. The group treated with 1% HA gel (P5) showed the highest average VEGF expression and angiogenesis compared with the negative control and lower-concentration treatment groups. These findings suggest that topical application of HMW-HA gel may enhance gingival wound healing in periodontal surgery by promoting angiogenesis and increasing VEGF expression
Orthodontic management of angle Class III malocclusion with severe anterior crowding
No full textDental malocclusion Class III is a challenging condition characterized by a Class III molar relationship, and it has a specific anterior condition according to Dewey classification. In some cases, Class III dental malocclusion with skeletal Class I may present with a convex rather than a concave profile. Several methods are available to correct a convex profile, including extraction, full arch distalization using TADs, intermaxillary elastic Class II, anterior segment retraction, and others. Combining more than one of these methods can be effective in correcting a convex profile. An 18 year-old woman presented to RSGM Universitas Padjadjaran with a diagnosis of Angle Class III dental malocclusion, skeletal Class I with a convex profile, normal maxillary incisor inclination, asymmetric profile, severe anterior crowding in both arches, minimal overjet, anterior crossbite, upper midline shift, clockwise rotation and high-angle mandible, and lingual inclination of the mandibular incisors. The patient was treated with a Roth prescription fixed orthodontic appliance. Maxillary and mandibular first premolars were extracted to create space, and lacebacks were applied to the canines to correct severe anterior crowding]. Bilateral intermaxillary Class III elastics were used to maintain the facial profile and prevent it from becoming concave. Treatment was completed in 18 months, achieving a Class I molar relationship, midline correction, optimal overbite and overjet, and preservation of the facial profile. This case report presents the orthodontic management of Angle Class III malocclusion with skeletal Class I and severe anterior crowding, successfully treated with first premolar extractions while maintaining a convex profile

No full textDental radiography services were at high risk of becoming sites for cross-infection during the COVID-19 pandemic. To minimize the spread of COVID-19, infection control adaptations were implemented in dental radiography services across various healthcare facilities, including Type A, B, C, and D hospitals, as well as clinical laboratories. This study aims to determine the differences in infection control practices of dental radiographic examinations during the COVID-19 pandemic at various health facilities. This cross-sectional study involved 42 dental radiographers who worked in Yogyakarta. Control infections were measured using the electronic questionnaire with 27 closed-ended questions. The data were analyzed statistically using the Kruskal-Wallis test, and descriptive analysis was continued by categorizing the control infection into high, medium, and low levels. The validity and reliability test showed that 18 questionnaire items were valid and reliable. The statistical test showed a p-value of 0.672 (p > 0.05) for the staff infection control and 0.147 (p > 0.05) for the room infection control. This study found no significant differences in infection control practices during dental radiographic examinations across various healthcare facilities during the COVID-19 pandemic. All facilities implemented high levels of infection control, with clinical laboratories showing the highest compliance. The study suggests increasing the number of questionnaire items related to room infection control and expanding the study’s scope in future research to improve accuracy and represent a broader population
The effect of activated charcoal and bentonite toothpaste on extrinsic tooth discoloration
No full textTooth discoloration is categorized into intrinsic and extrinsic types, with the latter caused by external staining agents such as pigmented beverages (e.g., black tea). Whitening toothpastes are commonly used to address extrinsic discoloration, though chemical-based formulations may lead to side effects. Consequently, natural alternatives, including activated charcoal and bentonite, are gaining attention as whitening agents. This study aimed to evaluate the effects of activated charcoal and bentonite toothpaste on extrinsic tooth discoloration. A control group pretest-posttest design was employed, involving 48 premolar teeth divided into four groups. Samples were stained by immersion in a black tea solution (400 mL water, 4 tea bags) for 4 hours daily over 13 days, simulating 7 months of tea consumption. Color measurements were conducted using a spectrophotometer before and after brushing. Brushing was carried out using an electric toothbrush with 0.5 g of toothpaste and 1 mL of distilled water for 2 minutes, twice daily, over 10 days. Repeated ANOVA analysis revealed significant differences in ΔE, ΔL, and ΔC values (p < 0.05). Activated charcoal toothpaste produced a marked lightening effect and increased color intensity, although no change was observed at the cervical region of the teeth. These findings suggest that activated charcoal may serve as an effective natural agent for managing extrinsic discoloration while further research is needed to clarify its long-term effects and clinical applications
Effectiveness of Catharanthus roseus L. extract gel on TNF-α and IL-1β in the healing process of oral lesions
No full textThe global incidence of oral lesions ranges from 5% to 66%, with an average of 20%. To date, no scientific research has investigated the effects of Catharanthus roseus L. (tapak dara) leaf extract on the expression of proinflammatory cytokines in oral lesion healing. This study aimed to evaluate the effectiveness of tapak dara leaf extract gel in reducing the expression of the proinflammatory cytokines TNF-α and IL-1β during oral lesion healing. A total of 30 mice (Mus musculus) were divided into five groups: four treatment groups and one control group, each housed separately. The gel formulation was prepared by mixing diluted extract solutions (5%, 10%, and 20%) into a 2% CMC-Na solution, heated and stirred for 10 minutes, and then cooled to achieve a gel consistency. Phytochemical screening was performed to qualitatively identify flavonoids, tannins, saponins, phenolics, alkaloids, steroids, and terpenoids. Expression levels of TNF-α and IL-1β were measured using an ELISA kit. ANOVA results showed that tapak dara leaf extract gel at 5%, 10%, and 20% significantly reduced TNF-α and IL-1β expression (p = 0.001). Tukey’s post hoc test indicated that the positive control (K+) group had the lowest expression of both TNF-α and IL-1β compared to other groups (p = 0.001). In conclusion, tapak dara leaf extract gel effectively reduces TNF-α and IL-1β expression, supporting its potential role in the healing process of oral lesions
