Cleft lip and palate is one of the most common congenital anomalies. Cleft lip and palate patients encounter growth problems in lip and palate area, although their overall growth and development remains unknown. Cervical vertebral maturation are indicators of physiological maturation used in interceptive treatment and orthognathic surgery. The present study aims to determine physiological maturation stage of cervical vertebrae maturation index in cleft andnon-cleft patients. Lateral cephalogram of 26 cleft patients and 27 non-cleft patients with a range of chronological age from 8-16 years old were involved. The cervical vertebrae maturation were analyzed in six stages of cervical vertebrae maturation method of Hassel and Farman. Data were analyzed using t-test (p≤ 0.05). The result shows that physiologicalmaturation stage of cervical vertebrae maturation index in cleft and non-cleft patients has no significant difference in stage acceleration (p= 0.38), stage transition (p= 0.41) and deceleration (p= 0.39). Likewise, there is no significant difference in physiological maturation stage of cervical vertebrae maturation index between cleft and non-cleft patients.

The development of technology in orthodontic field produces some orthodontic wires that have different deflection abilities. Loading force is the force needed to place an orthodontic wire in bracket slot (activation). Unloading force is the force produced by an orthodontic wire to move tooth (deactivation). Deflection test with three-point bending technique is a technique that is often used to determine the magnitude of the activation and deactivation force of orthodontic wire. Stainless steel (SS), nickel titanium (NiTi), copper nickel titanium (CuNiTi), and beta titanium (TMA), are the types of frequently used wires. This study aimed to compare loading and unloading force on the deflection test of SS, NiTi, CuNiTi, and TMA orthodontic wires sized 0.016 x 0.022 inch on the load-deflection graph. This is a laboratoryexperimental research on a total of 16 pieces of SS, NiTi, CuNiTi, and TMA orthodontic wires sized 0.016 x 0.022 inches. The group was divided based on the type of material. The deflection test was performed using a universal testing machine with a press speed of 5 mm/minute. Loading and unloading forces were recorded on deflections of 0.5; 1; and1.5 mm. Statistical tests of differences among groups were carried out by ANOVA analysis (p-value ≤ 0.05) and post-hoc analysis with T-test. There were significant differences in the loading and unloading forces recorded on deflections of 0.5; 1; and 1.5 mm; except for deflections of 0.5 mm of the SS and nickel-titanium wires. The wire deflection force fromthe lowest to the highest was CuNiTi wire, nickel-titanium wire, TMA wire, and stainless-steel wire.

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.
