Cleft lip and palate are the most common craniofacial anomalies in Indonesia. Recent publications report that there was delayed skeletal and dental age in cleft lip and palate patients. Panoramic and lateral cephalometric radiograph to evaluate growth and development through skeletal and dental age is still rarely used. The research aimed to determine the correlation between cervical vertebral maturation and teeth calcification stages in children aged 7 to 16 years old with cleft lip and palate in Unpad Dental Hospital. The research design was analytic correlation and the sample was selected using purposive sampling cross-sectional using secondary data panoramic and lateral cephalometric radiograph. The scores of cervical maturation and teeth calcification stages were then analyzed statistically using SPSS version 16. Spearman coefficient of rank correlation test showed strong correlation between cervical vertebral maturation and teeth calcification stages on all teeth, with the highest rs score was secondary molar (0.734) and p value 0.000 The conclusion of this research is that there is a strong correlation between cervical vertebral maturation and teeth calcification stages in children aged 7 to 16 years old with cleft lip and palate.

The increasing population of the elderly has an impact on health problems, including an increase of oral problems. One of the common oral problems is dry mouth that possibly disrupts gustatory function. The aim of this study was to investigate the relationship between salivary secretion and taste sensitivity level in the elderly. This study was a cross sectional study for the elderly population of Daerah Istimewa Yogyakarta/The Special Region of Yogyakarta (DIY) Province, Indonesia. This study consisted of interview, clinical examination, measurement of salivary secretion (sialometry) and taste sensitivity level using chemical gustometry method. Salivary secretion data were described in ml/ min. The measurement of taste sensitivity level was performed using 4 different substances: sweet (sucrose), salty (NaCl), sour (citric acid) and bitter (quinidine sulphate) with 4 different concentrations for each flavor. Four score was given if the respondent recognized the lowest concentration of the substance and 0 score was provided when all concentrations were failed to be tasted. Total score for test sensitivity level was scaled from 0 to 16. Salivary secretion data and taste sensitivity level data were analyzed by Spearman correlation test to determine the correlation between both variables. There were 103 subjects (70 women and 33 men) with the age mean of 65.61 years old, participating in this study. The mean of the sweet taste level was 2.81, 3.32 for salty taste, 3.69 for sour taste and 2.98 for bitter taste. Total taste sensitivity level mean was 12.80 out of 16. The measurements of unstimulated whole saliva showed a mean value of 0.170 ml/min with the majority of subjects having normal salivary flow. The Spearman correlation test results showed r= -0.078 with p >0.05 that indicated no correlation. We concluded that there was no relationship between salivary secretion and taste sensitivity level in the elderly.

Calcium is one of the most important minerals needed during hard tissue development. The preparation of this material into nano-sized particle is carried out to enhance the bioavailability and distribution of calcium in the body. Lack of calcium during odontogenesis causes defect in enamel such as hypoplasia and hypomineralization. During amelogenesis, after secretion of organic matrices, enamel mineralization will start in the presence of calcium. The objective of this study was to determine the effect of nano calcium supplementation during pregnancy on enamel development. In this study, 3-month-old female Sprague Dawley were mated and divided into three groups: nano calcium group (A), micro calcium group (B), and negative control group (C). The treatment was started on day 1 of pregnancy to day 1 after birth by intragastric administration method. The mandibles of 6 pups from each group were collected and stained with hematoxylin and eosin. Examination was conducted using microscope. Enamel deposition was measured using Optilab Image Raster® and the data collected was analyzed using t-test. Histological section of mandibular right first molar on Sprague Dawley newborn pups showed that enamel was observed on day 1 after birth but only on the group treated with nano calcium and micro calcium. Statistical analysis performed showed that the difference between the two groups was significant (p<0.05). From this study it can be concluded that the administration of nano calcium during pregnancy leads to rapid enamel deposition on Sprague Dawley pups.

One of the regenerative periodontal treatments for infrabony pocket is open flap debridement (OFD) with the addition of growth factor derived from platelet concentrate. Advanced platelet-rich fibrin (A-PRF) is a further development of plateletrich fibrin (PRF) with a lower centrifugation speed (1,500 rpm, 14 minutes). The purpose of this study was to examine the differences in periodontal tissue regeneration after the application of A-PRF and PRF in the treatment of infrabony pockets evaluated from probing depth (PD), relative attachment loss (RAL), and alveolar bone height. The samples were taken from 20 infrabony pockets divided into 2 groups: 10 subjects were treated with OFD+A-PRF and OFD+PRF on the remaining subjects. Probing depth (PD) and relative attachment loss (RAL) measurement were performed on days 0, 30, and 90. Bone height measurements were performed using CBCT X-rays on days 0 and 90. The results showed that PD and RAL reduction in the group of OFD+A-PRF was significantly greater than that in the OFD+PRF group. Bone height reduction in both groups showed no difference. The conclusion obtained from this study is A-PRF application enhances periodontal tissue regeneration by generating greater probing depth and relative attachment loss reduction compared toPRF, as well as an increase in bone height similar to in the treatment of infrabony pockets.

The thermoplastic nylon denture base material is prone to discoloration because its amide bonds absorb water easily. Titanium dioxide (TiO2) nanoparticle have long been used as a denture base coating. Meanwhile, coffee contains chlorogenic and tanic acid, which can change the color of denture bases. The purpose of this study was to examine the effect TiO2 coating and duration of coffee immersion on discoloration of thermoplastic nylon denture base. Samples consisted of 24 thermoplastic nylon in square-shaped (30 x 30 x 2 mm), divided into 4 groups (n = 6). They were control (without TiO2 coating) and treatment (with TiO2 coating) groups, which then were immersed in coffee solution for 15 and 30 days. Discoloration test was conducted using spectrophotometer by measuring the delta absorbance of light before and after coffee immersion. The result showed that the lowest delta absorbance was in the 15-day treatment group (0.011 ± 0.005) and the highest was in the 30-day control group (0.077 ± 0.027). Two-way ANOVA test showed that TiO2 coating and coffee immersion had an effect on discoloration of thermoplastic nylon (p <0.05). Post hoc LSD test showed that there were significant differences between the control and treatment group at 15 and 30 days of coffee immersion (p <0.05). In conclusion, TiO2 as a thermoplastic nylon denture base coating can reduce discoloration by coffee immersion for 15 and 30 days. There were no differences between 15 and 30 days of coffee immersion on thermoplastic nylon’s discoloration in the control and treatment groups.

Free radicals generated during ionization process of X-rays can damage biological tissues. Radiation exposure to gingival sulcus area will damage endothelial cells and increase permeability of blood vessels under sulcular and junctional epithelium. That inflammation will increase gingival crevicular fluid (GCF) volume. Repeated periapical radiographs often occurs due to the unfulfillment of quality assurance and leads to an increase amount of radiation dose received by the patient. Previous studies have shown that β-carotene mucoadhesive gingival patch can penetrate mucous membrane and provide protection against radiation by reducing the number of gingival epithelial cells micronuclei. The aims of this study was to observe β-carotene mucoadhesive gingival patch effect in GCF volume from patient exposed to repeated periapical radiographs. We recruited 10 participants from patients who receive repeated periapical radiographs in instalation of dentomaxillofacial radiology, Prof Soedomo dental and oral hospital Faculty of Dentistry UGM. The teeth of the subjects are divided into control and treatment group. β-carotene mucoadhesive gingival patch was applied to treatment group. GCF was collected using an absorbing paper strip before and after exposure, then measured bysliding caliper. Paired T-test showed significant differences (p<0.05) between GCF volume before and after radiographic exposure in each group. Independent T-test showed significant differences (p<0.05) of GCF volume between control and treatment group. Conclusion of this study is β-carotene mucoadhesive gingival patch significantly reduce GCF volume after repeated periapical radiographic exposure.

Hidrogen peroksida pada perawatan in-office bleaching meninggalkan residu yang dapat menghambat polimerisasi pada sistem resin bonding. Asam askorbat 10% sebagai antioksidan dapat mengeliminasi residu peroksida sebelum proses penumpatan. Kulit buah manggis (Garcinia mangostana) memiliki aktivitas antioksidan yang berpotensi untukmenggantikan peran asam askorbat. Penelitian ini bertujuan untuk membuktikan efek gel ekstrak kulit buah manggis dalam memperbaiki perlekatan komposit pada gigi pasca in-office bleaching. Penelitian ini merupakan penelitian eksperimental laboratorium. Sebanyak 25 gigi premolar pertama rahang atas dilakukan in-office bleaching danselanjutnya dibagi menjadi 5 kelompok terdiri dari kontrol negatif (tanpa agen antioksidan), kontrol positif (asam askorbat 10%), dan kelompok perlakuan gel ekstrak kulit buah manggis 10%, 20%, dan 40%. Perlekatan komposit ditentukan dengan uji geser, dilanjutkan pengamatan mikrostruktur permukaan email. Hasil penelitian menunjukkan nilai perlekatan komposit pada kelompok kontrol negatif dan kontrol positif berturut-turut sebesar 25,82±2,88 Mpa dan 37,68±1,06 Mpa. Pada kelompok perlakuan gel ekstrak kulit manggis 10%, 20%, dan 40% diperoleh nilai perlekatan berturut-turut sebesar26,54±2,68; 32,64±2,33; dan 57,34±1,51 Mpa. Nilai perlekatan komposit pada pemberian gel ekstrak kulit manggis 20% dan 40% berbeda signifikan dibandingkan dengan kontrol negatif maupun kontrol positif (p<0,05). Kenaikan konsentrasi gel ekstrak kulit manggis memberikan peningkatan jumlah fraktur email. Gel ekstrak kulit manggis 20% dan 40% dapat memperbaiki perlekatan komposit sehingga berpotensi sebagai agen antioksidan pada gigi pasca in-office bleaching. Effect of Mangosteen Gel on Shear Bond Strength Of Composite Post In-Office Bleaching. The residual peroxide after in-office bleaching inhibits the polymerization of the resin bonding systems. Ascorbic acid (10%) as anti-oxidant agent has a potential to remove the residual peroxide before restoration procedure. Mangosteen extracthas an anti-oxidant potential that can be used to remove the residual peroxide. The aim of the study is to prove the effect of mangosteen extract gel to improve shear bond strength of composite post in-office bleaching. The experimental laboratory design was implemented to this research. The study was carried out on 25 maxillary first premolars thathad been applied in-office bleaching procedure. The teeth were divided into five groups as follow: negative-control group (without anti-oxidant agent), positive-control group (10% ascorbic acid), and the treatment groups (10%, 20%, and 40% mangosteen extract gel). Shear bond strength of the specimens was tested and followed by microstructuretesting on email. The results show that negative-control and positive-control group scores were 25,82±2,88 Mpa and 37,68±1,06 Mpa, followed by the scores of 10%, 20%, and 40% mangosteen extract gel groups which were 26,54±2,68; 32,64±2,33; and 57,34±1,51 Mpa respectively. Significant higher shear bond strength values were observed in 20% and 40% mangosteen extract gel groups compared to the negative-control and positive-control group (p<0,05). The increasing concentration of mangosteen extract gel provided increasing number of email fractures. Mangosteen extract gel 20% and 40% improve the shear bond strength of composite, confirming its potential as an antioxidant agent for the teeth post in-office bleaching.

Acrylic resin is the most commonly used denture base material. However, it has a shortage of being easily broken. One way to resolve this problem is by adding polyethylene (PE) or glass fibers. The purpose of this research is to compare the transversal strength of PE and glass fibers from denture plate acrylic resin repair material. The experiment involved 32 plates of heat cure acrylic with the dimensions of 65 mm x 10 mm x 2.5 mm. The speciments were prepared to create a 3 mm gap and 45° bevel. Subjects were divided into 2 groups, each group containing 16 plates. Group I was reinforced with PE fiber and Group II was reinforced with glass fiber. All plates were soaked in distillation water for one day at 37 °C. Plates were tested for transverse strength with universal testing machine and all data were analyzed with independent t-tes at 95% confidence level. Macro photo analysis was used to observed the bond failure on fiber and resin. The mean of transverse strength (MPa) denture plate acrylic resin repair material reinforced with PE fiber was (67.38 ± 4.31) MPa, while glass fiber was (93.61 ± 6.14) MPa. Independent t-tes showed that type of fiber had a significant effect (p<0.05). Thus, it is possible to conclude that addition of glass fibers in denture plate acrylic resin repair material increased the transverse strength and made it stronger than those added with PE fibers.

Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic bacterium, which could aggressively infect immunocompromised patients and thus, cause high mortality rate. In addition, P. aeruginosa in oropharynx could be aspirated and cause ventilator associated pneumonia. Royal jelly is one of bee’s products that has been used for therapeutic needs including antibacteria. Adherence factor of P. aeruginosa were flagelum, pili and lectin. The aim of the study was to determine the effect of royal jelly to P. aeruginosa adhesion. Suspension of P. aeruginosa (ATCC® 27853) was incubated at 37 °C for 18 h. Treatment groups were exposed to royal jelly with several concentrations, 2%, 4%, 6%; while distilled water was being used as negative control. Bacterial adhesion test was determined using spectrophotometer λ = 600 nm to measure optical density values of adhered bacterial suspension in tubes. The result of one-way ANOVA showed significant differences (p<0.05) of optical density values among groups indicating that royal jelly affected the bacterial adhesion. LSD results showed significant difference of optical density values between 2%, 4%, and 6% royal jelly compared to distilled water. Six percent of royal jelly had the least optical density value compared to the other groups. In conclusion, royal jelly has the ability to decrease adhesion of P. aeruginosa. Six percent of royal jelly has better ability to decrease adhesion of P. aeruginosa than other concentrations.
