"ABSTRAKTo investigate the effect of alkaline peroxide type denture cleanser agents on the microbial profle, namely Streptococcus, Staphylococcus, and Candida species, in maxillary complete dentures. Methods: A total of 20 patients with maxillary complete dentures were recruited. Three denture cleanser agents were selected (n = 5): Polident (P); Steradent (S); and Pearlie White (PW), with distilled water (DW) as control. Dentures were brushed before immersion with denture cleansers. Denture bioflm was collected from the palatal impression surface of the denture before and after immersion. The collected microorganisms were cultured and colony forming units (CFU) were counted. Results: Signifcant reduction in the numbers of Streptococcus an Staphylococcus was observed after immersion with all denture cleanser agents (p< 0.05). On the other hand, no denture cleanser was signifcantly effective against Candida species (p>0.05). Furthermore, S was more effective among other cleansers compared to DW (p< 0.05). Conclusion: Immersion of dentures in denture cleansers can reduce the amount of microorganisms on denture surfaces; thus, leading to effective denture hygiene. Steradent denture cleanser showed the highest percentage reduction of polymicrobial organisms."

"Latar Belakang: Kemampuan mastikasi merupakan kemampuan untuk memecah partikel makanan agar mudah dicerna tubuh sehingga berperan dalam pemenuhan nutrisi. Penggunaan gigi tiruan lepasan diperlukan ketika seseorang mengalami kehilangan gigi karena dapat mengurangi kemampuan mastikasi. Berbagai faktor lain juga dapat mempengaruhi kemampuan mastikasi. Tujuan: Menganalisis hubungan berbagai faktor terhadap kemampuan mastikasi pemakai gigi tiruan lepasan. Metode: Tiga puluh empat pemakai gigi tiruan lepasan (GTL, GTLT, dan GTSL) berpartisipasi dalam uji mastikasi dengan permen karet yang dapat berubah warna (Masticatory Performance Evaluating Gum Xylitol®) dengan desain potong lintang. Laju alir saliva dievaluasi dengan gelas ukur, dan ketinggian residual ridge diukur secara klinis menggunakan kaca mulut No.3 yang diberi ukuran mm. Hasil: Ketinggian residual ridge (p=0,003) dan pengalaman memakai gigi tiruan (p=0,051) berperan terhadap kemampuan mastikasi. Faktor usia (p=1,000), jenis kelamin (p=0,711), laju alir saliva (p=0,400), jenis gigi tiruan (p=0,218), dan jumlah serta lokasi kehilangan gigi (p=0,097) tidak memberikan hubungan yang bermakna.

Background: Masticatory performance is the ability to breakdown food to facilitate digestion, and its role in nutrition is important. Removable dentures are used to rehabilitate loss of teeth, which could jeopardize masticatory performance. There are also various factors that affect masticatory performance.

Objective: To analyze the relationship between various factors and masticatory performance.

Method: Thirty four removable denture wearers (full dentures, single complete dentures, or partial dentures) participated in a cross-sectional study of masticatory performance using color-changeable chewing gum (Masticatory Performance Evaluating Gum Xylitol®). The volume of saliva were evaluated using measuring cups, and residual ridge heights were measured using modified mouth mirror no. 3 with metric measurements.

Result: Residual ridge height (p=0,003) and removable denture-wearing experience (p=0,051) had significant relationship with masticatory performance. Age (p=1,000), gender (p=0,711), saliva (p=0,400), denture types (p=0,218), the number and the location of missing teeth (p=0,097) did not have significant association with masticatory performance.

"Latar Belakang: Mastikasi terdiri dari proses penghancuran dan pencampuran makanan menjadi bolus yang siap ditelan. Kemampuan mastikasi dapat dievaluasi secara subjetif dan objektif. Evaluasi kemampuan mastikasi secara objektif dapat dilakukan dengan banyak metode, antara lain dengan color-changeable chewing gum dan gummy jelly. Color-changeable chewing gum dapat mengukur kemampuan mastikasi dalam pencampuran makanan. Gummy jelly dapat mengukur kemampuan mastikasi dalam penghancuran makanan. Color-changeable chewing gum dikatakan cocok mengukur kemampuan mastikasi pada semua golongan pasien, sedangkan gummy jelly dikatakan kurang cocok digunakan pada kelompok pasien dengan kemampuan mastikasi yang terkompromis. Penelitian lain mengatakan terdapat korelasi antara pengukuran kemampuan mastikasi dengan kedua bahan tersebut. Kemampuan mastikasi dapat dipengaruhi oleh faktor usia, jenis kelamin, indeks, massa tubuh, laju alir saliva, pH saliva, waktu pengunyahan , dan ambang batas penelanan. Tujuan: Menganalisis perbandingan kemampuan mastikasi pada pemakai gigi tiruan lengkap dan pasien bergigi lengkap dengan menggunakan color-changeable chewing gum dan gummy jelly serta faktor yang mempengaruhinya. Metode: Subjek penelitian 40 pasien pemakai gigi tiruan lengkap dan 40 pasien bergigi lengkap, dilakukan pengukuran kemampuan mastikasi dengan color-changeable chewing gum sebanyak 30,45, dan 60 stroke pengunyahan, pengukuran menggunakan gummy jelly sebanyak 10,20, 30 stroke, dan ambang batas penelanan, dan pemeriksaan faktor-faktor yang mempengaruhinya. Hasil: Kemampuan mastikasi pasien bergigi lengkap lebih tinggi dari pasien pemakai gigi tiruan lengkap (p<0,05) pada pengukuran menggunakan color-changeable chewing gum dan gummy jelly. Terdapat korelasi antara pengukuran kemampuan mastikasi menggunakan kedua bahan tersebut. Tidak terdapat hubungan yang signifikan antara kemampuan mastikasi dengan faktor usia, jenis kelamin, indeks massa tubuh, laju alir saliva, pH saliva, waktu pengunyahan, dan ambang batas penelanan. Kesimpulan: Kemampuan mastikasi pasien pemakai gigi tiruan lengkap lebih rendah dari pasien bergigi lengkap. Terdapat korelasi pengukuran kemampuan mastikasi menggunakan color changeable chewing gum dan gummy jelly.

Background: Mastication consists of comminuting and mixing food into a bolus and finally swallowed. Masticatory performance can be measures either subjectively or objectively.Various objective methods for evaluating masticatory function were introduced. Among them are using gummy jelly and color-changeable chewing gum. Color-changeable chewing gum can measure mastication ability in mixing food, while gummy jelly can measure ability in comminuting food. Mixing ability test using color changeable chewing gum was said to be suitable in all variations of dental status, while comminuting ability test was less suitable in group with compromised masticatory performance. In other research, the result showing correlation between both tests. Masticatory performance can be affected by factors such as age, gender, body mass index, salivary flow rate, saliva pH, chewing time, and swallowing threshold.

Objective: The aim of our study was to analyze masticatory performance as measured with gummy jelly and color-changeable chewing gum between complete denture wearers and dentate patients, and to analyze the correlation between masticatory performance with other factors such as age, gender, bodymass index, salivary flow rate, saliva pH, chewing time,and swallowing threshold.

Methods: 40 complete denture wearers and 40 fully dentate subject participated in this study. Two test food were used to evaluate masticatory performance: gummy jelly and color-changeable chewing gum. Subject was instructed to chew on the color-changeable chewing gum in 30, 45, and 60 strokes, and to chew gummy jelly in 10, 20, and 30 strokes. We also measure subjects swallowing threshold with gummy jelly.

Results: There was significant differences (p<0,05) between masticatory performance as measured with gummy jelly and color-changeable chewing gum in dentate subjects and complete denture wearers, which the first group had a better result. There was correlation between the measurement using both test foods. There was no correlation between masticatory performance with other factors such as age, gender, body mass index, salivary flow rate, saliva pH, chewing time, and swallowing threshold.

Conclusion: Masticatory performance in complete denture wearers is inferior compared to natural dentition subjects. There is correlation between masticatory performance measurement using gummy jelly and color-changeable chewing gum."

ABSTRACT

Phonetic disturbances or unclear pronounciation were often found in patients after insertion of maxillary complete denture. These disturbances could be assessed using palatogram of Indonesian linguo palatal consonant. One of the methods to improve phonetic adaptation was creation of palatine rugae on maxillary complete denture base. Palatine rugae functioned as tongue placement guidance on anterior palate to produce correct articulation of linguo palatal consonant sound, especially the letter lsquo t rsquo and lsquo d rsquo . The purpose of this study was to evaluate palatine rugae creation on maxillary complete denture bases that could affect phonetic adaptation. Respondents were 20 maxillary complete denture wearers, composed of 10 maxillary complete dentures with palatine rugae and 10 maxillary complete dentures without palatine rugae. Assessment was done using palatogram lsquo t rsquo and lsquo d rsquo pronounciation, and the similarity with Indonesian palatogram gold standard were evaluated. This study used cross over method and the factors considered in the relation with rugae were duration of usage, age, and sex. The result of this study was that it took 1 week to achieve phonetic adaptation of maxillary complete denture with palatine rugae. Mean scores in good lsquo t rsquo and lsquo d rsquo pronounciation were 60.15 and 69.65 with standard deviation 3.31 and 3.79. Conclusion of this study is maxillary complete denture with rugae palatine shortens phonetic adaptation. "
