CHA-collagen implantation to increase alveolar bone density
No full textTooth extraction is the common procedure in dentistry. This procedure causes a wound in teeth socket. Thus, the socket had to be secured to prevent over resorption of alveolar bone. This study used the third molar as a model to examine the third molar mandibular odontectomy routine procedure in oral and maxillofacial surgery. The new bone formation could be evaluated by radiographic examination. The aim of this study was to evaluate the effect of CHA-collagen implantation on the third molar mandibular bone density using 3D-CBCT to determine bone quality. The research was conducted by comparing extraction socket after the third molar mandible odontectomy, before and after graft material implantation. The subjects were divided into two groups. Group A consisted of six non-implanted subjects and group B consisted of six subjects with CHA-collagen implanted socket. Three dimensional CBCT evaluated alveolar bone density using pixel intensity at the socket area after odontectomy procedure and 10 weeks after. The result of t-test showed that CHAcollagen implanted socket had significantly higher pixel intensity than non-implanted group (p=0,046) until 10 weeks. Spearman test showed that the implanted CHA-collagen had a positive correlation with the increase of alveolar bone density (p=0.028; r=0.860) until 10 weeks. In brief, implantation of CHA-collagen increased bone density until 10 weeks
The retention difference between cobalt chromium and zirconia coping in different angulations on telescopic overdenture
No full textTelescopic overdenture is one type of removable denture that uses dual coping system that consists of primary and secondary coping. Retention of telescopic overdenture is obtained from the friction between primary and secondary coping, which is mainly influenced by the type of material and coping angulation. The purpose of this study is to determine the retention differences between CoCr and zirconia coping with 0°, 1°, and 2° angulations. Twenty four pairs of telescopic overdenture coping samples with 6 mm length were divided into 6 groups (n = 4), CoCr 0°, CoCr 1°, CoCr 2°, zirconia 0°, zirconia 1°, and zirconia 2°. Measurement of retention between coping is done by pull-off test using universal testing machine (UTM) and data were analyzed by two way ANOVA. The results showed that the largest average retention was found in zirconia coping with 0° angulation group (22.48 N), while the smallest average retention was found in CoCr coping with 2° angulation group (10.28 N). Two way ANOVA revealed that there were significant differences among groups (p<0.05). LSD tests showed that there were significant differences among all of groups. This study concludes that zirconia coping has higher retention than CoCr coping and coping with 0° angulation has the highest retention
Effect of collagen-chitosan hydrogel formula combined with platelet-rich plasma (A study of ph, viscocity, and swelling test)
No full textPlatelet-rich plasma (PRP) contains growth factors that speed up a healing process. The liquid form of PRP is difficult to be applied, so it needs material as a carrier of collagen. Collagen can be used as carrier materials and capable to activate growth factors and increase the concentration of the PRP to become a gel. Collagen often losses its shape and size due to degradation when exposed to body fluids. In the selection of materials, collagen can synthesize with chitosan. Collagen-chitosan hydrogel has potential as scaffold. Many formulations for proper hydrogel applied in the oral cavity need to pay more attention to several conditions, such as a neutral pH, high viscosity and ideal swelling. The aims of this study was to examine the influence of various formulations of collagenchitosan hydrogel PRPagainst pH, viscosity, and swelling. The study samples consisted of 25 collagen-chitosanhydrogel formulations. The samples were divided into five groups: 100/0; 75/25; 50/50; 25/75; 0/100. The first stage of the test was pH, viscosity and swelling measurement of the collagen-chitosan hydrogel to determine which ones matched the criteria. Collagen-chitosan hydrogel formulations were added with PRP with a ratio of 1:1. The second stage was to measure the pH, viscosity, and swelling measurement to see the results of the physical parameters of the hydrogel after mixed with PRP. The observation data were analyzed by t-test for pH and viscosity, while twoway ANOVA and post hoc LSD for swelling test. The results showed that collagen-chitosan hydrogel formulations of 25/75 and 0/100 met the criteria of pH, viscosity, and swelling. The pH of both groups showed no significant difference (p>0.05), but the viscosity and swelling variables showed significant difference (p<0.05). To conclude, collagen-chitosan hydrogel formulations mixed with PRP had no effect on pH, but had an effect on viscosity and swelling test. The collagen-chitosan hydrogel formulations mixed with PRP which matched the criteria were 25/75 and 0/100
The effect of fiber type and position on the transverse strength of an fiber reinforced composite (FRC) bridge
No full textFixed bridge made of porcelain fused to metal (PFM) is one of the widely used dentures. However, this type of denture is easily broken and cracked. As an alternative, a fixed bridge made of fiber-reinforced composite (FRC) is produced with more benefits since it is more efficient in terms of time and cost. The purpose of this research is to find out the effect of type and fiber position on the transverse strength of an FRC bridge. The experimentinvolved 35 rod of FRC with the dimensions of 25x2x2 mm3. Subjects were divided into seven groups, each of which containing five subjects. Group I, II, III was reinforced with glass fiber on compression side, neutral side, and tension side. Group IV, V, VI were reinforced with polyethylene (PE) fiber on compression side, neutral side, and tension side. Group VII was not reinforced with any fiber. Rods were tested for transverse strength with universaltesting machine and all data were analyzed with two way ANOVA at 95% confidence level. The results showed that type and position of fiber had a significant effect (p0.05). Least significance different post hoc test showed significant difference (p<0.05) for all groups, except between compression and no fiber. The conclusion of this research was that addition of glass fibers on tension side in bridge FRC increased the transverse strength to be higher than that with PE fibers. Fiber placement on tension side might improve the transverse strength than that of the other side

Two-piece hollow bulb obturator after partial maxillectomy on ameloblastoma case
No full textAmeloblastoma often occurs in the mandibular area, but 15 - 20% of ameloblastoma originates from the maxilla. Ameloblastoma lesions in the maxilla can be treated with partial maxillectomy, which produces defects that alter speech, swallowing function, and aesthetic. The role of prosthodontics is needed to rehabilitate the patient’s condition by fabricating an obturator that helps reduce the morbidity of patients. The main problem with the rehabilitation of substantial defects in the maxilla is the weight of the prosthesis, resulting in non-retentive prosthesis. The purpose of this case report was to evaluate the post-treatment of the partial maxillectomy in the case of ameloblastoma with the hollow bulb to rehabilitate the functions of mastication, phonetics, swallowing function, and aesthetic functions.This case report discussed the treatment of a 58-year-old female who undergone partial maxillectomy, has experienced tooth loss in 15, 14, 13, 12, 11, 21, 22, and 23, and had an anterior palate defect due to mass retrieval under the Aramany class VI classification. The chosen treatment was the fabrication of an obturator with the twopiece hollow bulbmade of acrylic resin. The results of the obturator insertion are good retention, stabilization,occlusion, aesthetics, clear phonetic, and the increasing patient’s confidence. The follow-up control after one week showed good retention, stabilization, occlusion, aesthetics, even clearer pronunciation and a good adaptation from the patient. This case report concludes that the two-piece hollow bulb acrylic resin obturator in ameloblastoma case can rehabilitate the maxillary defect post partial maxillectomy to restore masticatory, phonetic, swallowing and aesthetic functions
Effectivity of ozone water application on the socket after posterior tteeth extraction to accelerate clotting time phase
No full textAfter tooth extraction, dentists always place sterile tampons on the extracted socket to stop bleeding, to prevent infection and to reduce patients’ discomfort. Ozone is a biocompatible, bactericidal gas that can accelerate the healing of wounded soft tissue. In addition, it comes up with hemostasis effect to stop bleeding and may accelerate the clotting time and wound healing. Another advantage of ozone therapy is that it can be treated without making any trauma. The purpose of this research is to evaluate the effectivity of ozone water application in the socket to accelerate clotting time phase after posterior teeth extraction in 3 minutes, 6 minutes, and 10 minutes. This research was clinical experimental research with post-test only control group design. The research sampling was done through non-probability sampling. Then, sample was divided into two groups, each of which consisted of 15 patients treated with ozone tampons and 15 patients treated with sterile tampons after tooth extraction. Data were analyzed using chi-square test, and results showed a significant difference between the two groups. Ozone tampons show better result in accelerating clotting time after posterior teeth extraction than sterile tampons
Tongue coating index as a risk factor of decline of taste sensitivity in the elderly population
No full textThe elderly had various oral health issues, one of which is taste sensitivity. Taste sensitivity is highly affected by a person’s health, medication, eating habits, nutritional status, and oral hygiene. As an important organ for the sense of taste, the tongue can be covered in a white coating of debris, bacteria, and dead cells. To clean the tongue coating, one can do tongue brushing procedure, but this practice is not common among the elderly, especially in Indonesia. This cross-sectional study involved 114 older adults (n= 114) in the Special Region of Yogyakarta (Daerah Istimewa Yogyakarta- DIY), Indonesia, who were selected using stratified random sampling. The participants first signed the informed consent before undergoing an interview and going through oral clinical examination. This research particularly measured the tongue coating index and taste sensitivity level by way of statistically analyzing both variables to determine the correlation between tongue coating index and taste sensitivity level using three-dropmethod. Data from 114 subjects were presented descriptively using table and graphic. Most of the subjects 90.53% (103 subjects) had a coated tongue with various degree. The correlation statistic between tongue coating index and taste sensitivity level showed the statistically significant correlation (p-value = 0.019) and the coefficient correlation was -0.216, which means that there was a negative and weak correlation between both. Elderly with a higher tongue coating index tended to have less taste sensitivity. This could be due to debris blocking taste buds, thereby reducing taste sensitivity
Local application of biphosphonate as a biochemical barrier against bone graft resorption in mandibular reconstruction
No full textMandibular reconstruction to restore functions and aesthetics after mandibular resection remains a major surgical challenge. This type of reconstruction using non-vascularized autogenous bone graft harvested from iliac bone has been popular given that this bone is numerous and donor site morbidity can be minimized, however, it is highly resorbable. Local application of bisphosphonate by immersing bone graft in biphosphonate manages to inhibit bone graft resorption prior to the formation of new bone to support the osteogenesis and osteointegration of bone grafts. This paper aimed at examining the positive results of iliac bone graft osteogenesis and osteointegration following local application of bisphosphonate in mandibular reconstruction. A 22-year-old female patient came with a complaint of painless right cheek mass that has swollen slowly since 2 years. Radiographic examination showed cloudy radiolucent images in the right mandibular corpus to the right mandibular ramus, while histopathological examination indicated ossifying fibroma. Patient underwent mandibular resection followed by iliac bone graft-based mandibular reconstruction. Bone graft was immersed with bisphosphonate (zoledronate acid 0.005 mg /ml) for 3 minutes, then rinsed with saline for 3 minutes, followed by fixing bone graft on the reconstruction plate. Postoperative follow up in the 36th week showed no signs of infection and dehiscence in the surgery site, and the radiographic examination indicated signs of osteogenesis and osteointegration of mandibular bone graft. Local application of biphosponate on bone graft promotes favorable results of osteogenesis and osteointegration in mandibular reconstruction
