Abstract

Free radical residue due to intracoronal bleaching using 35% hydrogen peroxide (HP) can be removed with 35% sodium ascorbate (SA) combined with surfactants. This study aimed to determine the effect of surfactant concentration in SA 35% on the contact angle and tensile bond strength of composite resin after intracoronal bleaching with 35% HP. The contact angle was observed in 3 groups of 35% SA: group 1 (without surfactant); group 2 (with 0.2% surfactant); group 3 (with 0.4% surfactant). Each sample was dropped on a glass slide perpendicularly, then the image was taken at the fifth minute and contact angle value was obtained using ImageJ software. Tensile bond strength in this study used 21 premolars, which were cut and fixed with acrylic resin. 35% HP (0.01 ml) was applied to tooth surface for 5 days, then washed and dried. Specimens were divided into 3 groups, each of which was applied with 0.01 ml 35% SA without surfactant (group 1), 35% SA with 0.2% surfactant (group 2), and 35% SA with 0.4% surfactant (group 3) for 5 minutes, before they were washed and dried. All specimens were filled with composite resin, and incubated in artificial saliva for 7 days inside an incubator (37oC) before the specimens were tested with Universal Testing Machine (speed 0.5 mm/minute). ANOVA analysis showed the effect of surfactant concentration in 35% SA on the contact angle and tensile bond strength after intracoronal bleaching with 35% HP. In conclusion, 35% SA with 0.4% surfactant had a smaller contact angle and application of 35% SA with 0.4% surfactant after intracoronal bleaching with 35% HP had a greater tensile bond strength.

Abstract

Speech quality is an essential output in assessing the success of a palatoplasty. The goal of a palatoplasty is not merely to create a simple anatomical closure of the palate, but also to create an adequate velopharyngeal mechanism for a normal speech outcome and to prevent abnormal maxillofacial development after surgery. The aim of this study is to find out the difference in speech outcome between post-cleft palate closure patients and patients without cleft palate. An analytical retrospective study was conducted on 22 children (n = 22) with complete unilateral cleft palate, who had been treated using two flap push back technic of palatoplasty during 2014-2017 by purposive sampling method, and 22 children without cleft palate as the control group. The evaluation of speech outcome was done using an assessment of perception by doing a speech pathologist and instrumental examination by taking a lateral cephalometry radiograph. The perception was assessed by the articulation pattern, hypernasality, and speech intelligibility. The lateral cephalometry radiograph was taken at /i/ phonation to measure the distance velum to the posterior pharynx wall. Data were analyzed using Mann Whitney test. The velopharyngeal competence in post-palatoplasty group consisted of 22.8% adequate result, 0.1% marginal result, and 68.1% inadequate result. Meanwhile, in the control group, there were 72.7% adequate and 27.3% inadequate competence. According to the result of the statistical test, this study concluded that there was a significant difference in speech outcome based on articulation pattern, hypernasality, speech intelligibility, and velopharyngeal distance between post-cleft palate closure patients and patients without cleft palate (p < 0.05). Majority of patients after cleft palate closure with two flaps pushback technique had inadequate velopharyngeal competence with moderate-severe hypernasality, severe nasal emission, abnormal speech intelligibility, and velopharyngeal distance ≥ 5.0 mm, whereas the majority of control group had an adequate velopharyngeal competence.

Abstract

The minimally invasive surgical technique (MIST) is a method for periodontal regenerative treatment by minimizing trauma so it can preserve vascular supply of the interdental papillae. This study aims to determine the effectiveness of the MIST method with the addition of a combination of hydroxyapatite and β-tricalcium phosphate (HA + β-TCP) in treatment of infrabony pockets in terms of alveolar bone density and osteocalcin levels of gingival crevicular fluid. The study sample was taken from 20 teeth with infrabony pockets (n = 20), which were divided into two groups: 10 teeth treated with MIST and the other group with open flap debridement (OFD). Both groups received combination of HA + β-TCP. The osteocalcin levels of gingival crevicular fluid were checked on day-0 prior to the flap surgery, day-7 and day-14 after flap surgery using the Human Osteocalcin Elisa Kit. Radiological evaluation of alveolar bone density at day-0 and day-90 was done using cone beam computed tomography. Data of osteocalcin levels were analyzed using two-way ANOVA and continued with LSD Post Hoc test, while data of alveolar bone density reduction were analyzed using the Independent t-test parametric test. The results showed that there was no significant difference (p > 0.05) in the values of alveolar bone density between the MIST and OFD groups on day-0 and day-90, while the osteocalcin levels in both groups showed an increase from day-0 to day-7 and a decrease from day-7 to day-14. There was a significant difference (p < 0.05) on day-0 and 7 and day-7 and 14 between MIST and OFD groups. The MIST method with HA + β-TCP was effective and further increases alveolar bone density and osteocalcin levels of gingival crevicular fluid.

Abstract

Various biomaterials have been utilized as additional material to help tissue regeneration in the open flap debridement (OFD) procedure. Platelet-rich fibrin (PRF) is an autologous platelet concentrate that contains many growth factors (GFs) and generally used as an additional biomaterial in OFD. However, PRF has several weaknesses, such as its consistency, which is hard to mix with another biomaterial, and its abundant sediment of regenerative cells resulted from high-speed centrifugation. Injectable Platelet Rich Fibrin (I-PRF) is one of the PRF derivatives that contain more regenerative cells. Due to the low-speed centrifugation, I-PRF has a liquid form. Certain GFs were also found in I-PRF, such as PDGF, TGF-β1, VEGF, IGF, EGF dan COL-Ia. In this study, we measured probing depth (PD), relative attachment level (RAL), and bone height as the healing parameter, to see the effectiveness of I-PRF addition and bone graft in the OFD for infrabony pocket as the aim of this study. Twenty (20) periodontal pockets were chosen (PD= 5-7 mm) and divided into OFD+I-PRF+bone graft (bg) group (group I) and OFD+PRF+bg group (group II) equally. The clinical evaluation was measured at the baseline, day-30, and day-90. Results showed that PD (p= 0.022) and RAL (p= 0.008) significantly increased in group I (PD 2.80 ± 0.42; RAL 2.50 ± 0.52) compared to group II (PD 2.10 ± 0.73; RAL 2.00 ± 0.67); however, there was no significant difference in the bone height (p= 0.194). Taken together, our data revealed that I-PRF+bg induces soft tissue regeneration in infrabony pocket treatment.

Abstract

Temanggung Regency in Central Java is an area with an extensive tobacco farming, allowing its residents to have ease of access to cigarettes. In addition, it has become a tradition for locals in this area to serve any visiting guest with cigarettes. Adolescents start smoking to cope with the psychosocial crisis during their development, particularly when they try to find their identity. Smoking is, in fact, a risk factor for dental caries, so the adolescents in Temanggung have a quite high prevalence of caries. Thus, this study aimed to determine the sequence of the risk factors affecting the caries risk based on cariogram among male smokers aged 15-24 years (adolescents). This was a quantitative observational study with a cross sectional design. There were 152 subjects (n= 152) selected using a proportionate clustered random sampling out of the total population (316 adolescents). The research was carried out with a clinical examination of the oral cavity, measuring salivary secretions, examining the amount of plaque, and examining DMF-T. Scoring was done using a caliogram application. The results of this study showed that 81.3% of the adolescents had a moderate caries risk, while 18.1% of them had a high caries risk. The sequence of the risk factors affecting the caries risk based on cariogram was bacteria (22.90%), susceptibility (19.39%), dietary habits (12.09%), and other influencing conditions (7.55%).

Abstract

Epidemiological studies have shown that several factors, such as age, gender, tooth loss, socioeconomic status, cultural background, psychological stress of dental visit, and smoking can influence OHRQoL. Oral health is strongly age dependent, therefore OHRQoL differences are predicted to exist in the elderly group according to WHO. This condition is especially true for Rembang Regency due to the high population of the elderly and the shared ignorance on oral health given an overemphasis on other priorities, which will have an impact on their quality of life. The objective of this study is to know the OHRQOL difference in the elderly group in Rembang Regency with cross-sectional design. The research subjects were selected by inclusion and exclusion criteria with online informed consent. The questionnaire related to age and GOHAI was distributed and filled out online. Data were processed and analyzed using the Kruskall Wallis followed by Mann-Whitney post-hoc analysis and multiple linear regression test. A total of 222 respondents were involved (n= 222) consisting of 102 male and 120 female. The majority level of their OHRQoL were moderate (65.3%). The most affected dimension was physical function since it limits the type or amount of food intake (30.4%). The Kruskall-Wallis test showed significant OHRQoL differences in middle-age, elderly, old, and very old groups (p<0.05). The OHRQoL difference between middle-age and old and middle-age and very old obtained a significant result in the Mann-Whitney post hoc test with p value <0.05. Multiplelinear regression test showed a significant effect of age on OHRQoL with tooth loss as a confounding variable. Thus, Oral Health Related Quality of Life (OHRQoL) of the elderly group is significantly different.

Abstract

Improper placement of the reconstruction plate can lead to postoperative complications. Placing reconstruction plates that have arch for operation is made easier with the plate positioning guide (PPG) as a transfer method of reconstruction plate. This study aimed to assess the impact of PPG on the placement accuracy of reconstruction plate as determined by the symmetrical breadth of the mandibular arch and the consistent placement of reconstruction plate following hemimandibulectomy. According to the inclusion criteria, this was a retrospective cross-sectional study with 12 participants (n = 12) after hemimandibulectomy. Subjects were divided into PPG (n = 6) and Non-PPG (n = 6) groups. Measurement of the difference in the width of the mandibular arch and the height of the placement of the reconstruction plate between the reconstructed and non-resected sides in three positions (anterior, posterior, and angulus) was conducted using submentovertex radiographs and orthopantomogram (OPG) through the RadiAnt DICOM Viewer software. The placement accuracy of the reconstruction plates was analyzed using a one-sample t-test with p-value 0.05. The results showed that the placement accuracy of the reconstruction plate in the PPG group were accurate (p = 0.590), and the Non-PPG group was inaccurate (p = 0.000); with the independent sample test. There was a significant difference between the two groups (p = 0.000). Plate positioning guide provides better symmetry of the mandibular arch width post-hemimandibulectomy.

Abstract

There are only few studies on the antibacterial activity of red fruit extract (Pandanus conoideus Lam) against oral pathogenic bacteria. Thus, this study aims to determine the effectiveness of red fruit extracts by looking at the Minimum inhibitory Concentrations (MIC) and Minimal Bactericidal Concentrations (MBC) against periodontal pathogenic bacteria. The subjects of this study were Streptococcus mutans (ATCC 25175), Fusobacterium nucleatum (ATCC 25586), and Porphyromonas gingivalis (ATCC 33277). The antibacterial effectiveness of red fruit extract was tested by the liquid dilution method (microdilution). The data were analyzed using the one-way ANOVA test followed by a double comparison test with the Post Hoc Least Significance Different (LSD) test method. The red fruit extract effectively inhibited and eliminated test bacteria (p <0.05). Our study showed that the red fruit extracts at a concentration of 20% could inhibit the growth of Streptococcus mutans and Porphyromonas gingivalis, which was determined as the MIC strength of 80% as MBC of both bacteria tested. Furthermore, red fruit extract at the concentration of 10% showed an inhibitory effect on the growth of Fusobacterium nucleatum, which was determined as MIC of Fusobacterium nucleatum and the strength of 40% as MBC of Fusobacterium nucleatum. The red fruit extracts were significantly effective against the growth of Streptococcus mutans, Fusobacterium nucleatum, and Porphyromonas gingivalis provide essential information for further in vivo clinical studies to determine the exact dosage and clinical effectiveness of periodontal disease.

Abstract

Nickel-titanium archwires in orthodontic wires have nickel ion releases. The use toothpaste and saliva immersion time may cause its releases. This study aims to prove the difference and interaction between immersion time and toothpaste variations towards the amount of nickel ion releases at nickel-titanium archwires. The study was an experimental research with a post-test only control group design. Twenty seven nickel-titanium archwires were divided into three groups, i.e., K group, which were immersed in artificial saliva. P1 was immersed in artificial saliva and 1.5 gram of toothpaste A, and P2 was immersed in artificial saliva, and 1.5 gram of toothpaste B. The samples were incubated (37 °C) for 1 and 1.5 months. Nickel ion released was analyzed using SSA. Two Way ANOVA and Post Hoc LSD test were the statistic test used. The results of this study were the K group which released 0.112 mg/l and 0.685 mg/l, P1 which released 0.093 mg/l and 0.670 mg/l, and P2 which released 0.099 mg/l and 0.657 mg/l. There were differences in toothpaste variations (p = 0.029), differences in immersion time (p = 0.000) and there was no interaction between immersion time and toothpaste variations (p = 0.505) on the amount of nickel ion release. There was a significant difference in K-P1 (p = 0.038), K-P2 (p = 0.013), P1-P2 (p = 0.049). There was a difference in immersion time and toothpaste variation, but there was no interaction between immersion time and toothpaste variation towards the amount of nickel ion releases.

Abstract

Periodontitis is typically associated with disorders characterized by compromised tooth-supporting tissue. Damage to periodontal tissue is caused by an imbalance between matrix metalloproteinases and their inhibitors. Decreased tissue inhibitor and elevated matrix metalloproteinase levels result in collagen connective tissue and bone degradation. Several studies have shown that high levels of matrix metalloproteinase-13 (MMP-13) and low levels of tissue inhibitor of metalloproteinase-1 (TIMP-1) are also found in gingival crevicular fluid and saliva of patients with periodontitis. The purpose of this study was to determine the comparison of MMP-13 levels, TIMP-1 levels of saliva and bone density in patients with chronic periodontitis before and after scaling and root planning (SRP). The study samples were selected from patients who came for treatment at the Periodontics Installation of Universitas Sumatera Utara. A total of 16 patients were selected (n = 16) with a diagnosis of chronic periodontitis. The result showed that salivary MMP-13 levels in chronic periodontitis patients before SRP were higher than salivary MMP-13 levels after SRP and the difference was statistically significant (p < 0.05). It was also revealed that salivary TIMP-1 levels and alveolar bone density in chronic periodontitis patients before SRP were lower than that after SRP and the difference was statisticallysignificant (p < 0.05). There was a positive correlation between clinical parameters and salivary MMP-13 levels in patients with chronic periodontitis before and after SRP, but it was not statistically significant (p > 0.05). There was a negative correlation between clinical parameters and salivary TIMP-1 levels in patients with chronic periodontitis before and after SRP, but it was not statistically significant (p > 0.05).
