Decrease of physical and cognitive conditions in the elderly makes them become risky for periodontal disease. Lack of knowledge and poor behavior of oral health are the main causes of periodontal disease. Gingival health problems can be detected in the elderly by observing the signs and symptoms of gingivitis. This study was aimed to analyze the influence of knowledge and behaviour of oral health on perception of gingival health problems in the elderly living at Unit Rehabilitasi Sosial (nursery home) Pucang Gading Semarang. This was an observational and analytical study with a cross-sectional design. Samples were 74 elderlies at Unit Rehabilitasi Sosial Pucang Gading Semarang, obtained by using the purposive sampling method. Data were collected by using questionnaire and were analyzed by using the Gamma and Somers’d test followed by multinomial logistic regression test. The results showed that most of the elderly at Pucang Gading Social Rehabilitation Unit had poor oral health knowledge and oral health behavior. Most elderlies had moderate perception of gingival problems. Multinomial logistic regression about the influence of knowledge and behaviour of oral health on perception of gingival health resulted in a p-value of 0.000 (p<0.05). In conclusion, there was a significant influence of knowledge and behavior of oral health on the perception of gingival problems in the elderly.Keywords: oral health knowledge; oral health behaviour; perception of gingival problem; elderly  Abstrak: Penurunan kondisi fisik dan kognitif pada lanjut usia (lansia) menyebabkan mereka lebih berisiko terkena penyakit periodontal.

Type 2 diabetes mellitus (T2DM) is associated with many complications, one of them is oral health problem. Its risk increases in individual with poor oral hygiene. Oral health problem can impair daily life functions such as biting or chewing, speaking, and social interaction. However, research evidences investigating oral hygiene and quality of life related to oral health are still contradictory, therefore, further studies are still required. This study was aimed to evaluate the difference in oral hygine index and quality of life (QoL) related to oral health index between T2DM and non DM patients. This was an observational study with a cross sectional design. Samples consisted of 21 T2DM patients and non DM patients at the Internal Medicine Outpatient Clinic of RSND hospital. Oral hygiene examination (OHI-S) was performed on all patients. Moreover, all patients had to fill the questionnaire which evaluated their QoL related to their oral health conditions (OHIP-14). Data were analyzed by using unpaired T-test and Mann-Whitney test. The results showed that the means of OHIS index were 3.17 in T2DM group and 1.43 in non DM group (p<0.001). Meanwhile the means of OHIP-14 index were 7.14 in T2DM group and 2.24 in non DM group (p<0.001). In conclusion, T2DM patients significantly have worse oral hygiene index and QoL related to oral health index than non DM patients.Keywords:  type 2 diabetes mellitus (T2DM), oral hygiene, quality of life related to oral health  Abstrak: Diabetes melitus tipe 2 (DMT2) terkait dengan berbagai komplikasi, salah satunya masalah kesehatan rongga mulut yang risikonya semakin meningkat pada individu dengan kebersihan mulut yang buruk.

Background: Fire disaster is a non-natural disaster that often occurs. The impact is that victims are difficult to identify. One of the identification methods that can be used is dental restorative materials with observing changes in color and weight that occur in dental restorative materials due to exposure to high temperatures. Composite resin is a dental restorative material that is often used because it has good aesthetics, physical and mechanical properties. Purpose: This study to determine the effect of high temperature on weight and color changes in nanohybrid and bulkfill composite resin as a reference for forensic identification. Method: This research is an experimental laboratory with a pre and post-test control group design. A total of 30 nanohybrid composite resin samples and 30 bulkfill composite resin samples were divided into 5 groups consisting of 4 treatment groups and 1 control group. The treatment group was heated at four temperature groups, 30°C-200°C, 30°C- 400°C, 30°C-800°C and 30°C-1100°C using a furnace (Thermo Scientific, USA). Weight changes were measured using a digital scale (Ohaus,China) and color changes were observed using the Shade Guide (Vitapan Classical, Germany). Result: A change in color and weight of the nanohybrid composite resin and bulkfill after being heated at high temperatures. Two-Way ANOVA test and Post Hoc LSD test showed that there was a significant difference in weight between nanohybrid composite resin and bulk fill composite resin at each temperature interval (p<0.001). Conclusions: High temperature heating affects the color and weight changes of nanohybrid and bulkfill composite resin. Keywords: Bulkfill composite resin, High temperature heating, Nanohybrid composite resin

Decrease of stomatognathic organ function could result in decrease of quality of life (QoL) in geriatric patients. Temporomandibular disorder (TMD) creates a limitation in mouth opening, crepitation, and headache. This study was aimed to obtain the signs and symptoms of TMD through Fonseca’s Questionnaire in Semarang nursing home for elderly. This was a descriptive and observational study with a cross sectional design. Fonseca’s questionnaire and other questionnaires about medical history as well as dental and oral treatment history were used in this study. Fonseca anamnestic index was used to classify the TMD severity based on the total score of the answers. The chi-square was used to determine the differences between variables related to the TMD severity. The results obtained 57 respondents who were grouped based on age, sex, medical history, and dental and oral treatment history. There were 17 respondents without TMD, 18 had mild TMD, 12 had moderate TMD, and 10 had severe TMD. Besides age, emotional stress and tooth extraction were the most common causes and had significant effect on TMD severity (p<0.05). In conclusion, TMD severity will increase along with age, meanwhile, optimal dental and medical care can help to reduce the TMD severity in geriatric patients.Keywords: elderly, temporomandibular disorder, Fonseca's questionnaire  Abstrak: Penurunan fungsi stomatognatik dapat menyebabkan penurunan kualitas hidup pada lansia.
