Abstract

Platelet-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.

Abstract

Fixed 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 (p<0.05), while the interaction between type and position of fiber had no significant effect (p>0.05). 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.

Abstract

Ameloblastoma 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.

Abstract

The most common oral ulceration in the community might be as recurrent as aphthous stomatitis (RAS) or traumatic ulcer. The aim of this study was to report and analyze the characteristics of oral ulceration and risk factors based on an online survey. A questionnaire using Google forms containing a total of 34 questions. Four questions wereabout personal details, whereas 30 questions related to oral ulceration were recorded and presented descriptively. The chi square test was carried out to determine the relationship between several questionnaire variables. A total of 208 respondents were involved, consisting of 162 female and 46 male. Respondents were in the age range of 0–50 year old with >23 year old as the age group with the highest number of respondents (53%). Oral ulceration data showed no recurrence in 157 respondents (75%), rare recurrence/ once in a year (52%), frequent recurrence in the labial mucosa in 121 respondents, single ulcer (86%), round shape (75%), risk factor due to trauma (biting/friction) in 165 respondents, ulcer untreated (64 %), and ulcer recovery of less than 7 days (70%). The respondents had no symptoms of anemia (73%), and were not on a vegan diet (98%). Chi square test indicated that there was a significant correlation between trauma and the poor diet (p= 0.001). The data in this present study indicate that the characteristics of oral ulceration might lead to RAS or traumatic ulcers and this might be attributed to local (trauma) and systemic (diet) factors.

Abstract

Herpes-associated erythema multiforme (HAEM) is an acute inflammatory mucocutaneous disease which is characterized by ulcerative lesion on oral mucous membrane with or without skin involvements. The etiology of erythema multiforme (EM) is probably hypersensitivity reaction to human herpes simplex virus tipe 1 (HSV-1). Lesions on lips with HAEM can be treated by corticosteroid and acyclovir topically and/or orally. The objective of this study wasto report the case of HAEM with painful ulcers accompanying with crust on lips. A 55 years old woman complained painful ulcers with crust on lips since the last five months. She had visited a primary health care service and received several medications such as antibiotic (ciprofloxacin), anti-inflammatory drug (corticosteroid), analgesic (mefenamic acid) but her complaint was never healed completely because it was always recurring. The lesion on her lips got worse when she ate hot and spicy food and after she went out for outdor activities. She had a history of herpes virus infection seven months before but it was completely healed after treated by acyclovir topically and amoxicilin orally. An extra oral examination found black brown crust on her upper lip vermillion, well-demarcated, irregular margin, rough surface, erythematous surrounding area, accompanied with pain. An intra oral examination identified ulcers, yellowish, 4-5 mm in size, well-demarcated, irregular margin, redness in surronding area, accompanied with pain. Acomplete blood count examination, serology test for HSV-1 (IgM and IgG) were taken and the result showed that only IgG was reactive. The therapies given to the patient were topical medications with a combination of corticosteroid, chloramphenicol and moisturizer, followed by methyl prednisolone and acyclovir orally. After 6-week treatment, the lesions were completely healed.Herpes-associated erythema multiforme (HAEM) caused by hypersensitivity reactionto herpes simplex virus type 1 (HSV-1) may have a characteristic of painful ulcers accompanied with crust on the lips. The combination of both anti-inflammatory and antiviral drugs can be a choice for the therapy.

Abstract

Yogyakarta is a province in Indonesia with the highest prevalence (2.4%) of Diabetes Mellitus (DM). Around 90% of diabetic patients suffer from type 2 DM. Oral manifestations of DM may disturb oral functions which in turn influence oral health - related quality of life (OHRQo)L. This study aimed to evaluate the OHRQoL of type 2 DM outpatients in Yogyakarta General Hospital. The study subjects comprised 50 male outpatients and 32 female outpatients with type 2 DM (40-81 years old). Geriatric Oral Health Assessment Index (GOHAI) and Xerostomia Inventory were used to assess OHRQoL and xerostomia status, respectively. Intraoral examinations comprising periodontal tissue, oral hygiene (OH), coated tongue, and present teeth were performed. There were 49 (59.76%) subjects with low and 33 (40.24%) subjects with high score of GOHAI; 78 (95.12%) with and 4 (4.88%) without periodontal tissue defect; 79 (96.34%) with poor and 3 (3.66%) good OH; 17 (20.73%) with coated tongue >50% and 65 (79.27%) with coated tongue ≤50%; 34 (41.46%) with present teeth <20 and 48 (58.54%) with present teeth ≥20; and 39 (47.56%) with xerostomia and 43 (52.44%) with normal status. Only ‘present teeth’ had a significant contribution to the proportion of GOHAI status in type 2 DM patients in this study (p=0.032). Type 2 DM patients with ≥20 teeth had a more significant proportion of high GOHAI status compared to those with <20 teeth. The majority of type 2 DM outpatients of Yogyakarta General Hospital had poor OHRQoL as reflection of their oral condition that is partly contributed by patients with present teeth <20.

Abstract

Post bleaching procedures often have free radicals trapped in dentin tubule and interprismatic enamel, leading to demineralization and denaturation. Sodium ascorbate is an antioxidant substance known to bind residual free radicals to stop demineralization and denaturation. The purpose of the study was to assess the calcium and phosphorus loss from the dentin surface following bleaching by 35% hydrogen peroxide and reversal by 35% sodium ascorbate andthe surface structure of the dentin. Six sound premolars were divided into their crown and root sections, with the crown subsequently being cut into four equal parts to obtain 24 samples. The calcium and phosphorus contents as well as the surface structure of the dentin were assessed using SEM-EDX. These were then divided into four groups, each containing six samples. Group A (control): the samples were bleached by 35% hydrogen peroxide, immersed in an artificial saliva, stored in an incubator at 37 °C for seven days. Group B: the samples were bleached by 35% hydrogen peroxide followed by the application of 35% sodium ascorbate for 5 minutes (once). Group C: the samples were bleached by 35% hydrogen peroxide followed by the applications of 35% sodium ascorbate (twice). Group D: the samples were bleached by 35% hydrogen peroxide followed by the applications of 35% sodium ascorbate (threetimes). The calcium and phosphorus contents as well as the surface structure of the dentin were re-assessed using SEM-EDX at the same locations. The results of one-way ANOVA indicated a difference in the calcium loss in the four treatment groups (p<0.05), but there was no difference in the phosphorus loss. An LSD test showed that there was a difference in the calcium loss between group A and groups C and D or between group B and groups C and D. The dentin tubules in group A were larger than group B, C and D. The frequency of 35% sodium ascorbate application had an effect on the calcium loss and the surface structure in the dentin bleached by 35% hydrogen peroxide.

Abstract

Hypertension and osteoporosis are believed to be linked to to each other. Previous studies have suggested that the imbalance of calcium metabolism in hypertensive condition and the use of calcium channel blockers such as amlodipine may lower the density and quality of bone. Panoramic radiography has been widely used as a reliable tool in assessing bone quality. One indicator of bone quality in panoramic radiograph is the macrostructure evaluation of mandibular cortical bone by using various indexes such as mandibular cortical index (MCI) and antegonial index (AI). This research aimed to compare the bone quality of hypertensive patients with amlodipine and healthy individuals using MCI and AI. In this study we used sixty panoramic radiographs of hypertensive patients with amlodipine and healthy individuals, thirty for each group, with various aspects of demography. The MCI analysis was done by dividing the mandibular cortical shape into three different qualitative categories and the AI analysis was done quantitatively by measuring the width of mandibular cortical bone in antegonial region using ImageJ software. There were statistically significant differences in the results between the two groups in terms of both AI (p = 0.000) and MCI (p = 0.001) in which hypertensive group had lower score. Based on this research, there were differences of mandibular bone quality of hypertensive patients with amlodipine and healthy individuals, particularly in its macrostructure.

Abstract

Frame denture generally uses Co-Cr alloy. However, alloy is expensive, so dental laboratories use residual sprue casting for recasting. The purpose of this study was to determine the effect of Co-Cr alloy recasting on fracture toughness. This was a laboratory experiment, with five sample groups, namely R0: 100% of new alloys; R1: 50% one-time recasting procedure and 50% new alloys, R2: 50% two-time recasting procedure and 50% new alloys, R3: 50% three-time recasting procedure and 50% new alloys, R4: 50% four-time recasting procedure and 50% new alloys. Fracture toughness was tested using a universal testing machine; the data were analyzed by One-Way Anova test and LSD (p>0.05). The results showed that the fracture toughness was 233.103 MPa-m1/2 in R4, and the highest was 242.435 MPa-m1/2 in R0. The results of the analysis by the LSD test on fracture toughness showed that there were no significant differences in R0 with R1 and R2, but there were significant differences between R0 with R3 and R4. There was a decrease after recasting in each group because of the missing elements of the Co-Cr alloy. The percentage of each element decreased due to oxidation and evaporation during heating. There was a change in the composition of the Co-Cr alloy in R3 and R4. There was a decrease in the fracture toughness. Variation in recasting frequency of Co-Cr alloy affected the fracture toughness. In each sample groups, the fracture toughness of Co-Cr alloy decreased after recasting.

Abstract

The asessment of cranio-facial structures forms a part of orthodontic diagnosis and treatment. One of the most frequently used cephalometric analysis is the Down’s analysis. It consists of 10 parameters of which 5 are skeletal and 5 are dental. Down has based his findings on 20 Caucasians, which have physical characteristic differences with Papuans. Indigenous Papuans are people of Melanesian descent consisting of indigenous tribes in Papua province and/or people who are accepted and recognized as Papuans by indigenous Papuans.The use of cephalometric values in different racial types, may result in the incorrect orthodontic diagnosis and treatment plan. According to those, the objectives of this study are to determine reference values for Down’s cephalometric analysis in papuans, to evaluate the differences exists between Papuan adult male and female, and also to compare the mean difference between persent study and established value of Down’s norms. A study was conducted on 16 lateral cephalograms of Papuans that have been selected based on inclusion criteria. The Down’s method was used for the cephalometric analysis. The data obtained was processed statistically to determine the mean, standart deviation, and minimum-maximum value, and presented in the form of frequency, table, or diagram. The result showed that the normal cephalometric values of papuans different from the normal values used in the Down’s analysis. The values obtained in this research is expected to be a reference in conducting Down’s cepahlometric analysis in Papuans for orthodontic treatment purposes.
