As we know a successful endodontic treatment requires a thorough knowledge of internal and external tooth morphology, correct interpretation of radiographs, and adequate access to and exploration of the tooth’s interior. This case report presents the endodontic therapy of rare case of Radix Entomolaris in mandibular first molar with three roots( mesial, distal and distolingual) and five canals namely mesiobuccal, mesiolingual, distobuccal, first and second distolingual.
Maxillary anterior teeth are the most affected teeth from dental trauma. The immediate reattachment of natural tooth fragment is a good alternative option as an emergency treatment for remaining aesthetical and functional problem. This treatment offers a conservative, aesthetic, and cost effective restorative option that has been shown to be an acceptable alternative to the restoration of the fractured area with composite resin or crown. In this case report we presents a clinical technique of reattachment of coronal fragment of maxillary central & lateral incisor after trauma using glass fibre – reinforced composite post systems.
ANTICANDIDA ACTIVITY OF ETHANOL EXTRACT JERINGAU (Acorus calamus L) RHIZOME AGAINST Candida albicans ISOLATE REMOVABLE FULL DENTURE ACRYLIC
Background: Maintaining denture hygiene by brushing and soaking it in disinfectant can prevent Candida infections. Jeringau (Acorus calamus L) is an herbal plant that its rhizome extract has antifungal activity against Candida albicans. Aim of study: This study aimed to measure whether the value of minimum inhibitory concentration (MIC50) of ethanol extract rhizome of Jeringau against C.albicans isolates the maxillary removable full denture acrylic. Materials and methods: Rhizome of jeringau was prepared. In vitro, study was conducted laboratory experimentally with ten samples tested by serial dilution ethanol extract rhizome of jeringau method with eight different concentrations. They were dropped to 0,1 ml C. albicans and incubated at 37 oC for 24 hours and repeated twice. They were grown on Sabouraud Dextro Agar medium that were incubated and seen its growth. Results: Inhibition zone extract of rhizome jeringau concentration 100% on plate I (9,4 mm) and plate II (8,85 mm). MIC50 of ethanol extract rhizome of jeringau is 2,5 mg/ml. Conclusion: Rhizome of jeringau containing β-asarone which is the major active component of antifungal against C. albicans. It was terpenoid group. Terpenoid caused porin damage. When porin was broken it would reduce the permeability of fungal cell wall resulting in fungal cells would lack of nutrients, thus the growth of fungi was inhibited
The term talon cusp defines a wide variety of accessory cusp-like structures, ranging from an enlarged cingulum to a well-delineated anomalous cusp, reported mainly on the permanent dentition, and very rare in the primary dentition. In primary dentition, maxillary central incisors are most commonly affected by this anomaly. This is a rare case report of a 4-year-old female patient with a talon cusp affecting the mandibular primary lateral incisor.
Unilateral cleft lips are considered to be one of the most common genetic and environmental birth defects globally and regionally, this review shines the light on the different approaches in treating and managing unilateral cleft lips. The different approaches are Millards Technique, Mohlar and finally True Triangle By Dr Abdullah Al Atel. The management of such deformity requires full understanding of all measures to achieve ultimate result of treatment. The Aim of this study is to come up with the most suitable as well as the least failure percentage approach among the three techniques.
Aim: To evaluate the color stability of dual cure and light cure resin cements immersed in coffee solution at different time periods (baseline, 3 days and 1 week). Materials and methods: The color stability of three light curing (Variolink Esthetic (VLC); Rely X Veneer (RLC) and Mojo Veneer (MLC)) and three dual curing (Variolink Esthetic (VDC); Rely X Ultimate (RDC) and Breeze (MDC)) resin cements were tested. A total of sixty disks (10 mm diameter and 0.5 mm thickness) were prepared using a silicone mold (n=10). The specimens were subjected to baseline color measurement using Commission Internationale de l’Eclairege L*a*b* (CIELAB) color space system with the help of a spectrophotometer (LabScan XE, HunterLab, VA, USA). Following baseline color measurements, the specimens were immersed in a staining coffee solution. The color measurement was repeated after 3 days and 1 week of immersion in coffee solution. All the data collected were statistically analyzed using repeated measures of Analysis of variance (ANOVA, P
Gender discrimination is the important aspect of the human identification procedures that help in the establishment of biological profile from the skeletal and dental remains and also help in the facial reconstruction of unidentified bodies. Age, race, sex and stature determination along with dental evidence collection and facial reconstruction over the skeletal remnants are the important specialties of the forensic dentistry. The present study evaluates and compare the impact of mandibular canines in gender identification and also to determine any discrimination in the canine index among the different races (Malay, Chinese and Indian) of the Malaysian population.
Marginal fit of fixed dental prostheses is determined by the size of the gap between the margin of the restoration and finish line of the prepared tooth. The most important factors influencing marginal and internal fit of fixed dental prostheses are the material used, the type of finish line as well as peculiarities of various technique of restoration fabrication. The objective of the article is to review the literature about the marginal and internal fit of various fixed prosthetic constructions. A review of literature using Pubmed, Google Scholar, and Research Gate database was carried out and 73 articles mostly in English were selected. The keywords were “Computer-aided design, marginal gap, internal fit, marginal fit, and crown adaptation”. Clinically accepted boundary value of marginal gap is considered to be ≤100 μm. However, a number of factors such as milling machine, parameters of bur (diameter, sharpness), software, design preparation, smooth preparation margins and incorporation of rounded line angles on the tooth preparation, the type of finish line, material and fabrication method of the construction and type of impression method should be taken into consideration in order to achieve these results. The perfect marginal and internal fit are the guarantee of construction success and longevity. As a sizeable marginal opening concedes more plaque accumulation, gingival sulcular fluid flow and bone loss, following in microleakage, recurrent caries, periodontal disease and a decrease in the longevity of the prosthetics restorations. Currently used techniques of restoration manufacturing, including constructions manufactured by computer aided design/computer aided manufacturing system can provide clinically allowable marginal fit.
Background: Recently, the concept of minimally invasive (MI) dentistry has emerged. MI calls for the selective removal of heavily infected and irreversibly denatured dentin caused by carious lesions while preserving dentin that is demineralized but not infected. Aim: To compare the minimal invasive potential (MIP) of conventional caries excavation (CCE), caries detection dye (CDD), and fluorescence aided caries excavation (FACE) methods in children. Subjects and Methods: A total of 105 carious primary molars in 43 children were included in this study. The teeth were randomly divided into three groups according to the caries excavation method. Preoperative evaluation of the carious teeth was performed using digital radiography after sealing the cavities with a radiopaque material. Caries excavation was performed using CCE, CDD, or FACE method. The teeth were restored using self-cured glass ionomer. Post-operative radiographic examination was then performed. Pre-operative and post-operative widths and depths for the cavities were assessed. MIP was determined by comparing the prepared-cavity width and depth relative to the initial width and depth of the caries lesion, respectively. Results: There was no statistically significant difference between the MIP of examined groups neither after comparing cavity widths at p=0.253 nor depths at p=0.06. FACE showed the highest mean values of MIP potential for cavity widths (1.41±0.36) and depths (2.04±0.74). Conclusions: CCE, CDD, and FACE showed comparable MIP in children.
Clinical Evaluation of Self Ligating Versus Conventional Ligating Preadjusted Edgewise Brackets- A Prospective Clinical Study
Objective: The prospective study was taken up with null hypothesis that there is no difference clinically in treatment efficiency and gingival condition before start of treatment & twelve months after bonding in SLB and CLB system. Materials and Methods: This clinical study include 30 patients, divided into two groups of 15 each were included in the present study. Intraoral photos and study models taken at pre-treatment (T0), 5 weeks (T1), 10 weeks (T2) and 15 weeks (T3). Initial alignment was assessed by using the Little irregularity index (LII) in the mandibular anterior teeth. The subjects were also examined for bleeding potential of the tissues by using Gingival Index (GI). Results: The mean initial irregularity (MII) score for SLB T0, T5, T10 and T15 was 5.867, 2.252, 0.516 and 0.039. MII score for CLB T0, T5, T10 and T15 was 6.000, 3.630, 1.589 and 0.327. A two sample t-test revealed gap of 4.02% was statistically significant (T= 2.80, 0.012). This data suggests that total alignment change of mandibular arch from T 0 to T 15 was better in SLB compared to CLB group. The mean increase of GI with SLB system was 0.183 while for CLB were equal to 0.98. This difference of GI between SLB and CLB before and after twelve months of bonding was statistically significant (T= -2.96, P value=0.010). Conclusion: The present study could facilitate the orthodontist to compare the potential benefits of SLB over the CLB system that facilitate less gingival bleeding and increase in alignment efficiency.
