The 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.

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.

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.

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.

The availability of X-rays in dentistry may help visualize the stage of development of dental maturity. The high prevalence of malocclusion in a population and contradictory research results on dental maturation in each skeletal malocclusion encourage the authors to know the maturity pattern of the posterior mandibular teeth in each skeletal relation and the difference in women and men. A cross-sectional study was conducted with a sample size of 214 panoramic and cephalometric radiographs from skeletal malocclusion patients based on ANB angle (class I: 73, class II: 75, class III: 56) with an age ranging from 8 to16 years old. Maturation of the second premolar and second molar was assessed using Demirjian method. Statistical analysis used the non-parametric Kruskal Wallis test to show the difference in maturity patterns in each class of skeletal relations and Mann Whitney test to show the difference in females’ and males’ maturity patterns. There were significant differences in females and males dental maturity patterns in which female dental maturation was advanced than male. Differences in each skeletal relationare not significant.

Telescopic 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.

Nanofilled composite resin is one of restorative materials with some weaknesses, such as changes of colour and surface roughness. These weaknesses are attributed to some factors, including frequent consumption some beverages, including yoghurt drinks. This study aims to determine the effect of long immersion of nanofilled composite resin in guava yogurt drink on discoloration and changes in surface roughness. Subjects of the study were nanofilled composite resin materials (3M Filtek Z350XT shade A3) in cylindrical shape with a diameter of 10 mm and 2 mm thickness. Study was conducted by immersing nanofilled resin composites in 10 mL of guava yogurt drink at 37 °C. Twelve specimens were divided into 3 groups with immersion duration of 12 hours, 24 hours, and 36 hours. Surface roughness measurements were carried out using a profilometer Starrett SR300 surface roughness tester, while the colour measurement parameters according to the system L * a * b * was measured using chromameter Konica Minolta CR-400 before and after treatment. Data of changes in surface roughness and colour changes data (ΔE) were calculated and analysed using one-way ANOVA. The results showed insignificant surface roughness changes but significant colour changes in nanofilled composite resin in the groups of 12 hours, 24 hours, and 36 hours. It is concluded that immersion duration in guava yoghurt drink significantly affects the colour of nanofilled composite resin.

The prevalence of oral diseases in Indonesia is 25,9% in 2018, the highest percentage is recorded being caused to dental caries. Oral condition which may be acidic due to foods is potential to cause dental caries, as oral bacteria activities such as S. mutans may transform foods into becoming acids. In current condition, it is difficult for people to detect their own acid and base oral condition independently. This study aimed to create an innovation of a chewing gum supplemented with red cabbage (Brassica oleracea var. capitata f. rubra) extract which has functions as oral pH detector. The chewing gum was made by mixing the maceration extract of red cabbage and gumbase. This study was performed by using a qualitative test of pH 1-13 buffer solution colour change and pH 5-9 artificial saliva which was added by the extract, and then tested with manufactured chewing gum. Anthocyanin level was tested by using a 520 and 700 nm UV-Vis spectrophotometer. The study resulted in colour change in colour qualitative test. On pH 5-9 artificial saliva, colour change happened in order of orange, orange-brown, brown, brown-green, and green, after it was mixed with chewing gum. Colour compatibility test on chewing gum and artificial saliva showed a compatibility percentage of 80. Chewing gum supplemented with red cabbage can be used as pH detector of pH 5-9 artificial saliva.

In current condition, it is difficult for people to detect their own acid and base oral condition independently. This study aimed to create an innovation of a chewing gum supplemented with red cabbage (Brassica oleracea var. capitata f. rubra) extract which has functions as oral pH detector. The chewing gum was made by mixing the maceration extract of red cabbage and gumbase. This study was performed by using a qualitative test of pH 1-13 buffer solution colour change and pH 5-9 artificial saliva which was added by the extract, and then tested with manufactured chewing gum. Anthocyanin level was tested by using a 520 and 700 nm UV-Vis spectrophotometer. The study resulted in colour change in colour qualitative test. On pH 5-9 artificial saliva, colour change happened in order of orange, orange-brown, brown, brown-green, and green, after it was mixed with chewing gum. Colour compatibility test on chewing gum and artificial saliva showed a compatibility percentage of 80. Chewing gum supplemented with red cabbage can be used as pH detector of pH 5-9 artificial saliva.","PeriodicalId":31262,"journal":{"name":"Majalah Kedokteran Gigi Indonesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78736044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

Nickel-titanium (NiTi) arch wire has properties that favor its use during the leveling and aligning phase of orthodontic treatment. This NiTi orthodontic arch wire has the potential to experience nickel ion release. One factor that can cause the release of nickel ions is toothpaste. Nickel ions released can enter the body and cause carcinogenic, mutagenic, cytotoxic, and allergic effects. The purpose of this study was to see the differences of nickel ions released from NiTi orthodontic arch wire after immersion in detergent and non-detergent toothpaste. This was a laboratory experimental research to draft a comparative design. The sample size was 40 pieces of NiTi orthodontic arch wire which were divided into 2 groups, immersion in detergent toothpaste and immersion in non-detergent toothpaste. The sample used was NiTi arch wire solution immersed in toothpaste and distilled water for 24 hours in an incubator at 37 °C then measured using inductively coupled plasma (ICP) mass spectrometer to determine the released nickel ions. Data were analyzed usingMann-Whitney test. The Mann-Whitney test resulted in a value of 0.872 (p≥0.05) which indicates no significant difference between the two groups. The study concluded that there is no difference in the nickel ions released from NiTi orthodonticarchwire after immersion in detergent and non-detergent toothpaste.
