Effect of two different materials in sealing vertical root fractures of intentional replantation on epithelial thickness of periradicular tissue
No full textVertical root fractures of intentional replantation need a material capable of binding the fragments of the fracture line tightly and encouraging the regeneration of periradicular tissue. One of the indicators that regeneration of periradicular tissue takes place is epithelial thickness. This study aimed to investigate the effect of mineral trioxide aggregate (MTA) and self-adhesive resin cement as the adhesive materials in sealing vertical root fractures of intentional replantation on the epithelial thickness of periradicular tissue. This study used 27 male New Zealand rabbits with the age range of 8-12 weeks. The mandibular incisor was extracted, and the tooth was cut from the cervical border to the 2/3 apical third. The samples were assigned randomly into three groups of 9 each, namely Group 1 with no application of any material in the fracture line (control group), Group 2 with MTA, and Group 3 with self-adhesive resin cement. All the teeth in all the groups were then inserted back into the socket. Each group was further divided into three subgroups based on the observation time, namely days 7, 14, and 21. Histological observations of the epithelial thickness were carried out under the light microscope (400x magnification). Data were analyzed using a two-way ANOVA and LSD post hoc test with a confidence level of 95%. The two-way ANOVA analysis showed that the materials used for sealing the fracture lines had a significant effect on the epithelial thickness (p0.05). No interaction occurred between the material used and observation times (p>0.05). It can be concluded that MTA generated a greater epithelial thickness of periradicular tissue compared than self-adhesive resin cement in sealing vertical root fractures of intentional replantation

No full textBacterial adhesion of Streptococcus mutans to cobalt chromium recast alloys
No full textCobalt chromium (CoCr) alloys are utilized to make dental prosthesis. Casting CoCr alloys is a common operation in dentistry laboratories due to its low cost. Casting surplus (metal remaining in the sprue and crucible former) is frequently reused by dental laboratories to reduce and recycle metal waste. However, the quality and safety of these recast alloys require further information. Microbial attachment to the surface of metal prostheses may affect its quality and safety. Biofilm formation on metal surface can cause biocorrosion and secondary infection. The effects of different proportions of recast Cobalt Chromium alloy on the bacterial adhesion are not clear. The purpose of this study was to investigate how recasting affects the Streptococcus mutans (S. mutans) adhesion. Twenty disk-shaped specimens (n= 20, allocated for 5 groups) were prepared from CoCr alloys (Remanium GM; Dentaurum) with different proportions (100% new alloy, 25% recast alloy, 50% recast alloy, 75% recast alloy, and 100% recast alloy). After the immersion of the specimens in bacterial suspension for 24 hours, the number of bacteria that adhere to the specimen’s surface was counted using Colony Forming Units. Data were analyzed with one-way ANOVA (α = 0.05). The bacterial adhesion was significantly affected by the recast alloys (p < 0.05). An increased proportion of CoCr recast alloys showed an increase in S. mutans adhesion to the specimen surface
The effect of adding zirconium dioxide nanoparticle to acrylic denture base on porosity and candida albicans adhesion
No full textAcrylic resin is the most common fabricated material for denture bases. ZrO2 nanoparticles can be used as filler to strengthen the physical properties and inhibit the adhesion of acrylic resins. This study aimed to examine the growth of Candida albicans and porosity in reinforced acrylic resin with Zirconium Dioxide (ZrO2) nanoparticles at 2.5% and 5% a concentration targeted for denture bases application. A laboratory experiment study included twenty-seven disc-shaped samples which were divided into three groups: group I acrylic resin without ZrO2 nanoparticles (control), group II acrylic resin with 2.5% ZrO2 nanoparticles, and group III with 5% ZrO2 nanoparticle acrylic resin. Samples were collected by heat polymerization while porosity observations were done using primo zeizs starr (Nikon YS100) microscope at 100x magnification. Dilution test was implemented to assess Candida albican growth. One-way ANOVA and Post Hoc LSD test statistical analysis were performed to evaluate the data (p<0.05). The results indicated that the mean porosity values in the control group of 2.5% and 5% were 37.4 ± 3.5, 15.8 ± 3.3, 8.0 ± 2.0 respectively while the attachment of C. albicans was 0.832 ± 0.083, 0.536 ± 0.098, 0.218 ± 0.083. One-way ANOVA confirmed a significant effect (p<0.05). Similarly, Post Hoc LSD test reported significant difference (p<0.05). The results showed that acrylic resin reinforced with ZrO2 nanoparticles for heat-polymerized denture base effectively reduced porosity and C. albicans adhesion. Five percent of ZrO2 nanoparticle concentration presented greater porosity reduction compared to 2.5% ZrO2 and non-reinforced acrylic resin. Acrylic resin reinforced with ZrO2 nanoparticles in 2.5% and 5% concentration is fungistatic
The correlation of zinc serum levels and zinc intake with taste disorders in elderly patients at Babatan Public Health Center Bandung
No full textTaste disorders, which can be caused by various factors, including deficiency of zinc levels in the body and lack of zinc, generally occur in the elderly. The aim of the study was to analyze the correlation between zinc serum levels and zinc intake, as well as the correlation between salivary volume, hypertension, and smoking with taste disorders in the elderly. This was analytical observational research with a cross-sectional method, which was conducted on 100 elderly patients, at Babatan Health Community Center, Bandung, Indonesia. The sampling was conducted through the following: interview about systemic disease history, drugs taken, and smoking habits; examination of oral cavity conditions; nutrition intake interviews; taste tests tests; and zinc serum measurement using the atomic absorption spectrometry. The data were obtained statistically. Among these one hundred elderly patients, 79 had low zinc serum levels and 94 had inadequate zinc intake. The average zinc serum in the elderly patients with taste disorders was 40.1 μg/dl, whereas those without taste disorders was 72.4 μg/dl, with a p value of <0.001. The average zinc intake in the elderly patients with taste disorders was 3.4, whereas in those without taste disorders was 6.0, with a p value of <0.027. Smoking correlated with taste disorders, while salivary volume and hypertension had no a correlation with taste disorders. There was correlation between zinc serum levels and zinc intake on taste disorders in the elderly patients. Smoking had a relationship with taste disorders in the elderly patients, whereas salivary volume and hypertension had no correlation with taste disorders in the elderly patients
Relationship between premolar extraction on the dimension of upper airway and tongue posture in skeletal class II malocclusion
No full textCorrection of skeletal Class II malocclusion with camouflage orthodontic treatment generally requires the extraction of the maxillary first premolars to provide space for retraction of the maxillary incisors. Retraction of incisors changes the position of the incisors and the dimensions of the dental arch, which can cause changes in tongue posture and affect the upper airway. The purpose of this study was to determine the relationship between premolar extraction on the dimensions of upper airway and tongue posture in skeletal Class II malocclusion. This study was designed as a retrospective cohort using lateral cephalometric radiographs before and after orthodontic treatment. The samples in this study consisted of 44 samples of adult patients (n = 44) aged 18-40 years, who were divided into 2 groups: 22 subjects treated without premolar extraction and 22 subjects treated with premolar extraction. Lateral cephalometric radiographic analysis were used to measure the dimensions of the upper airway by analyzing superior posterior airway space (SPAS), middle airway space (MAS), inferior airway space (IAS), vertical airway length (VAL), and tongue posture (tongue length and height tongue) using imageJ software. No Statistically significant different changes were observed as seen from the following results: SPAS (p = 0.709), MAS (p = 0.365), IAS (p = 0.562), (p = 0.401), tongue length (p = 0.578), tongue height (p = 0.086) in the sample group without extraction premolar. No significant alterations in the upper airway and tongue posture measurement were observed in the sample group with extraction premolar. Premolar extraction with retraction on upper incisors did not affect upper airway dimensions and toung posture in skeletal Class II malocclusion.
