Abstract

Tooth extraction can lead to alveolar bone resorption, requiring regenerative approaches using biomaterial scaffolds combined with stem cells. Chitosan–hydroxyapatite (CS–HA), a well-established scaffold that mimics the composition of human bone, combined with stem cells represents a promising strategy to promote bone formation. This study aimed to evaluate the effect of chitosan–hydroxyapatite (CS-HA) scaffolds seeded with cryopreserved human adipose-derived mesenchymal stem cells (hADMSCs) on bone sialoprotein (BSP) secretion. The hADMSCs used in this study were commercially obtained cryopreserved cells (ATCC® PCS-500-011™) and were characterized by flow cytometry. Scaffolds were fabricated using a freeze-drying method by combining chitosan and hydroxyapatite in a 1 : 1 ratio, followed by freezing at −80 °C. A post-test-only control group design was employed, consisting of 36 samples divided into three groups: positive control (CS-HA + hADMSCs + a-MEM), negative control (hADMSCs + osteogenic medium), and treatment (CS-HA + hADMSCs + osteogenic medium), and BSP levels were subsequently quantified on days 7, 14, 21, and 28 using ELISA. One-way ANOVA demonstrated a significant difference among groups (p = 0.000), with the highest BSP secretion observed in treatment group on day 14 (BSP levels 44.29 ± 2.58), followed by treatment group on day 28 (BSP levels 46.19 ± 7.64).  The significantly elevated BSP secretion in the treatment group on day 14 demonstrates osteoinductive characteristics of the CS-HA scaffold, supporting its potential application in bone tissue engineering and regeneration.

Abstract

Oil 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.

Abstract

This study aims to evaluate various flap incision techniques utilized in the mandibular third molar removal surgery. A systematic review with a qualitative approach was conducted. Data were obtained from published journals through manual database searches via Scopus, ScienceDirect, and PubMed covering the period from 2000 to 2024, using predetermined keywords related to the topic. The PRISMA statement guidelines were followed, including the use of the official flow chart. Twenty-one journals were identified and analyzed to compare different flap designs in mandibular third molar extraction procedures, focusing on their relationship with wound healing processes and complication rates. Comparative analysis of flap incision techniques was performed through systematic evaluation of multiple journal data. Both envelope and triangular flaps demonstrated comparable healing times in third molar extraction procedures. The envelope flap, while minimally invasive, showed association with dry socket occurrence. The triangular flap provided superior surgical access and demonstrated pain reduction following mandibular third molar surgery. The pedicle flap showed effectiveness in preventing dry socket and alveolar osteitis. In addition, the Lingual-based triangular flap proved superior to buccal-based triangular flap in controlling postoperative pain, swelling, and trismus while reducing overall complications. This analysis demonstrates that flap design selection significantly influences postoperative outcomes in mandibular third molar surgical procedures. Both triangular and envelope flap can be considered for the procedure of mandibular wisdom teeth removal.

Abstract

Artificial teeth elements are essential components of removable dentures. Inadequate cleaning can lead to the accumulation of microorganisms, which may cause denture stomatitis. Alkaline peroxide effervescent tablets are commonly used denture cleansers. However, prolonged use may increase the surface roughness of artificial teeth. To address this, an alternative natural-based cleanser has been formulated using red watermelon (Citrullus lanatus) rind extract in effervescent granule form. Effervescent granules of watermelon rind extract have potential as an alternative denture cleanser due to their antibacterial properties. The effervescent reaction helps mechanically remove plaque and debris while inhibiting the growth of microorganisms that cause odor and infection. This formulation is practical, natural, and economical. The study aims to evaluate the effect of immersion in effervescent granules containing watermelon rind extract on the surface roughness of artificial teeth. This was a laboratory experimental study using acrylic resin-based artificial teeth. Samples were divided into three treatment groups: aquadest, alkaline peroxide effervescent solution, and watermelon rind effervescent granule solution (n = 5). Surface roughness was measured using a Surface Roughness Tester, and data were analyzed with the Kruskal–Wallis test (p < 0.05). The mean surface roughness values after immersion in aquadest, alkaline peroxide solution, and watermelon rind effervescent granules were 0.140 ± 0.026 µm, 0.616 ± 0.213 µm, and 0.670 ± 0.041 µm, respectively. The findings demonstrate that immersion in effervescent granules containing watermelon rind extract significantly increases the surface roughness of artificial teeth. Further formulation development is recommended to optimize its potential as a natural denture cleanser.

Abstract

Stunting refers to a condition of short stature in toddlers due to delayed growth from the prenatal period until the age of 24 months. Chronic malnutrition in stunted toddlers leads to protein deficiency; therefore, active substances are needed for maximum protein absorption. Pineapple core (Ananas comosus) contains bromelainenzymes and citric acid, whichcan enhance protein absorption in conditions of chronic malnutrition and increase saliva flow rate.This study aims to investigate the effect of pineapple core extract on growth parameters and saliva flow rate in stunted Wistar rats. This study involved 16 male Wistar rats, which were divided into four groups: a negative control group (no treatment), a treatment group (75% pineapple core extract), a positive control group 1 (FeSo4 supplements), and positive control group 2 (pilocarpine hydrochloride). Growth parameters and saliva flow rate were measured before and after pineapple core extract treatment. The research results were analyzed using one-way ANOVA followed by Tukeys test, which showed a significant difference between the treatment group and the other groups in body weight (p = 0.037), body length (p = 0.028), tail length (p = 0.003), and saliva flow rate (p = 0.000). Administration of 75% pineapple core extract resulted in increased growth parameters (body weight, body length, and tail length) and saliva flow rate in stunted rats.

Abstract

Radicular 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.

Abstract

he bond strength between lithium disilicate veneers and tooth structure depends on factors such as curing technique and luting agent. Preheated composite resins have been proposed as alternative luting agents due to their favorable mechanical and polymerization properties. This study aimed to evaluate the effects of conventional, ramp, and pulse light-curing techniques on the shear bond strength of lithium disilicate when preheated microhybrid and nanohybrid composite resins were used as luting agents.  Forty-two maxillary premolars were prepared and randomly assigned to six groups (n = 7) based on the combination of luting agent and light-curing technique: IA (microhybrid–conventional), IB (microhybrid–ramp), IC (microhybrid–pulse), IIA (nanohybrid–conventional), IIB (nanohybrid–ramp), and IIC (nanohybrid–pulse). Lithium disilicate veneers were cemented accordingly, and shear bond strength was evaluated. Results from a two-way ANOVA indicated a significant effect of the type of preheated composite resin on the shear bond strength of lithium disilicate (p < 0.05), while no significant effect of light-curing technique was observed (p > 0.05). This study confirmed that preheated microhybrid composite resin produces greater shear bond strength compared to preheated nanohybrid composite resin. Light-curing technique does not significantly affect the shearbond strength of lithium disilicate.

Abstract

Alveolar socket preservation (ASP) requires an ideal barrier membrane that provides anti-bacterial activity, water contact angle (WCA) and swelling behavior to support bone regeneration. This study evaluated these characteristics in a Polyvinyl Alcohol-Collagen-Hydroxyapatite composite membranes derived from the scales of Lates calcarifer.L. The PVA-Col-HA CM was produced from the scales of Lates calcarifer through mixing, homogenization, casting, and drying and then divided into three groups: non-irradiated, 15 kGy irradiation, and 25 kGy irradiation. Antibacterial activity was assessed by disk-diffusion test and inhibition zone diameters were measured. Water contact angle was determined using a contact angle goniometer on both membrane surfaces. Swelling behavior was evaluated by immersing samples in phosphate-buffered saline for 60 minutes, followed by periodic weighing and calculation using a swelling formula. The anti-bacterial activity test showed a larger zone of inhibition in the 25 kGy group by 2mm on Escherichia coli and Staphylococcus aureus. One-way ANOVA test of WCA values showed significant differences (p < 0.05) among groups, with the 25 kGy group exhibiting the highest hydrophilicity. Analysis of swelling behavior using ANOVA and Kruskal-wallis test showed no significant differences (p > 0.05) among groups, but the linear graph shows that the 25kGy group displayed the lowest and most stable swelling profile. These findings suggest that the PVA-Col-HA CM exhibited favorable anti-bacterial activity, WCA, and swelling behavior, with optimal performance observed in the 25 kGy irradiation group.

Abstract

Sinonasal carcinoma (SNC) is a rare but aggressive malignancy often diagnosed at an advanced stage. Total rhinectomy, though potentially life-saving, results in significant functional and psychosocial impairments. This case highlights the use of a custom-made room temperature vulcanizing (RTV) silicone nasal prosthesis as a non-invasive rehabilitation option post-rhinectomy. A 50-year-old male presented with persistent nasal discharge and epistaxis. Imaging and biopsy confirmed high-grade non-intestinal type sinonasal adenocarcinoma, staged as T4aN0M0 (Stage IVA). The patient underwent total rhinectomy followed by radiotherapy. After sufficient healing, maxillofacial prosthetic rehabilitation was initiated. The nasal prosthesis was fabricated using RTV silicone and retained with eyeglasses. At one-month follow-up, the patient reported excellent prosthetic function, aesthetic satisfaction, and improved self-esteem, with no complications. This case demonstrates that custom-made nasal prostheses using RTV silicone can effectively restore aesthetics and function following total rhinectomy. It further underscores the importance of a multidisciplinary approach and individualized treatment planning in optimizing patient outcomes.

Abstract

An increase in the frequency of 35% hydrogen peroxide (HP) application during intracoronal bleaching leads to a higher accumulation of free radical residues, which can negatively affect the bonding of composite resin. The removal of these free radicals can be facilitated by the application of 35% sodium ascorbate (SA) combined with 0.4% surfactant. An additional frequency of SA application is required to counteract the increased free radical residues. This study aimed to evaluate the effect of the frequency of 35% SA combined with 0.4% surfactant and different intracoronal bleaching frequencies on the shear bond strength of composite resin. Forty-eight premolar teeth were divided into two main groups of 24 specimens each. Group I received two applications of 0.01 mL HP 35%, while Group II received three applications. After each bleaching session, the specimens were stored in a closed tube for five days per session, then washed and dried. Each group was further divided into three subgroups. Subgroup A was left untreated for seven days; Subgroup B received two applications of 35% sodium ascorbate combined with 0.4% surfactant; and Subgroup C received three applications. All specimens were restored with composite resin and immersed in pH 7 artificial saliva in an incubator for seven days. Shear bond strength was tested using a Universal Testing Machine at a crosshead speed of 0.5 mm/min. Two-way ANOVA revealed a significant effect of sodium ascorbate application frequency and different intracoronal bleaching frequencies on composite resin shear bond strength (p < 0.01). The results indicate that the shear bond strength of composite resin subjected to three applications of 35% sodium ascorbate combined with 0.4% surfactant is statistically comparable to those obtained with two applications of the same formulation.
