Authors: Bala Oya , Üçtaşli Mina Betül , Ünlü Liknur 
Published: July 2019

AbstractRecently, new resin-based composites, called “packable” or “condensable” resin composites, are being promoted as amalgam alternatives. The purpose of this study was to evaluate leakage in Class II cavities restored with the five packable resin-based composites. On 45 freshly extracted human molars, cavities were prepared following a standardized pattern in which the Class II cavity had a length of 3.0 mm, width of 2.0 mm, and depth of 1.5 mm occlusally. The proximal box had an axial depth of 1.5 mm and a buccolingual width of 4.0 mm. The cervical margin was located 1.0 mm below the cement enamel junction (CEJ). The teeth were randomly divided into five groups of 8 each. The cavity surface was conditioned with 36% phosphoric acid, rinsed, excess water removed, and a dental bonding adhesive (Prime&Bond NT) was used for all the cavities. The teeth were then restored according to the manufacturer's instructions: Group 1, Surefil; Group 2, Solitaire; Group 3, Alert; Group 4, Filtek P60; and Group 5, Prodigy Condensable. After the restorations were completed, the specimens were finished and polished with an aluminum-oxide-coated disc, thermocycled, stained, sectioned, and viewed under a stereomicroscope for leakage at occlusal/enamel and gingival/dentin margins.All test groups showed that leakage of gingival/dentin margins were greater when compared with leakage of occlusal/enamel margins. At the occlusal/enamel margins, there were no significant differences between the materials; however, at gingival/dentin margins, Filtek P60 and Prodigy Condensable demonstrated less leakage, while Solitaire demonstrated greater leakage.CitationBala O, Üçtasli MB, Ünlü I.

The Effect of Fiber Position and Polymerization Condition on the Flexural Properties of Fiber-Reinforced Composite
Authors: Lassila Lippo V.J. , Vallittu Pekka K. 
Published: July 2019

Abstract
The aim of this study was to investigate the influence of the position of the fiber rich layer on the flexural properties of fiber-reinforced composite (FRC) construction. In addition, the total residual monomer content of FRC was quantitatively determined to find out the difference of the effectiveness of two types of light-curing units using liquid chromatography (HPLC). Unidirectional continuous E-glass FRC and hybrid particulate filler composite resins were used in the fabrication of test specimens. Four different positions of the FRC layer were used: compression, neutral, tension, and vertical side position. A three-point bending test (ISO 10477) was performed to measure the flexural properties of the specimens. Position of the FRC layer had a significant effect on the flexural strength (p<0.001, ANOVA). Also, the type of light-curing device had an effect on flexural strength (p<0.001). Specimens with FRC positioned on the compression side showed flexural strength of approximately 250 MPa, whereas FRC positioned on the tension side showed strength ranging from 500 to 600 MPa. Mean flexural modulus with FRC placed horizontally ranged between 9-12 GPa; no significant difference was found between these groups. However when fiber reinforcement was positioned vertically, the flexural modulus raised up to 16 GPa. Specimens with 24 vol% glass fibers contained 52% less residual monomer than specimens without glass fibers. The monomer content was lower in specimens polymerized with the curing device with higher polymerization temperature. In order to optimize flexural strength of low fiber volume fraction, the fibers should be placed at the tension side of the specimen.

Authors: Chung Evelyn M. , Sung Eric C. , Sakurai Kari L. 
Published: July 2019

Abstract
About 40% to 50% of Down syndrome (DS) patients can have significant congenital heart defects such as patent ductus arteriosus, Tetralogy of Fallot, and septal defects. Patients with large septal defects may develop Eisenmenger syndrome (ES), which is defined by the cardiac septal defect and pulmonary hypertension coupled with a reverse right to left shunting of blood flow. DS patients that suffer from this condition require special considerations in the delivery of their dental care to prevent further medical complications or emergencies such as infection, cyanotic episodes, and thromboemboli. Collaboration with the cardiologist is also essential to ensure a complete and comprehensive pre-operative work up. The purpose of this article is to describe the dental management of DS patients with ES under general anesthesia.

Partial Spontaneous Bone Regeneration Subsequent to Mandibulectomy
Authors: Martins Wilson Denis , de Castro Ávila Lucia Fátima 
Published: July 2019

Abstract
A case of spontaneus bone regeneration after mandibulectomy is presented. The patient was young and had a mandibular resection performed for a large fibroma. Only one of the condyles was preserved. Partial preservation of the periosteum may play an important role in rapid bone regeneration. In this case bone regeneration occurred only in mandibular regions where the periosteum could be preserved.

Authors: Chasteen Joseph E. , Murphy Gretchen , Forrey Arden , Heid David 
Published: July 2019

Abstract
This article reviews the issues related to the Health Insurance Portability & Accountability Act (HIPAA) security rule that apply to dental practice. The security rule specifically addresses individually identifiable health information that is transmitted or maintained in electronic media. System security must be applied to the entire technical infrastructure for the practice environment as well as to the work culture on a daily basis and must be thought of as an enterprise asset. Security refers to all of the policies, procedures, tools, and techniques used to assure that privacy and confidentiality are adequately addressed in a healthcare system. HIPAA requires all covered entities that transmit or maintain electronic health information perform, and document, a risk assessment for security and develop a security plan to address major areas of concern. A self-assessment tool is provided in this article.

Lateral Perforation in Parallel Post Space Preparations
Authors: Maden Murat , Alaçam Tayfun , Tinaz Ali Cemal , Topuz Özgür , Er Özgür 
Published: July 2019

Abstract
This study evaluates the amount of remaining tooth structure and possibility of producing lateral perforation following the use of different diameters of parallel-sided Parapost drills in groups of different canal curvatures (0〬-15°, 16°- 25°, 26°<) in distal canals of first and second mandibular molar teeth.
After enlargement of root canals using the crown-down pressureless technique, Parapost drills #1, #2, and #3 were used in the different canal groups for the preparation of a post space. Standardized digital radiographs were taken before the post space preparation and after each Parapost drill application. Four horizontal lines (a, b, c, and d) were drawn at equal distances on these images, starting from the pulp chamber floor moving apically at 2 mm increments. There were no significant differences between the different curvature groups at the a, b, c, and d levels for the critical level of the remaining tooth structure (multiple comparison test; p>0.05). However, in considering root perforation, both at the inner and outer side of the roots, there were statistically significant differences at “c” and “d” levels in group 3 (#3 drill) without taking into account the root curvature (ANOVA; p<0.5). None of the specimens showed strip perforation.

Published: July 2019

Abstract
The aim of the current investigation is to evaluate optimal pontic and retainer fiber positions for Polyethylene fiber-reinforced composite (FRC) restorations. In series I notch disc specimens were used to mimic loading cuspal regions of pontics. Four groups (n=15/group; codes A to D) were prepared from Artglass composite. Groups A to C were reinforced with polyethylene fibers, and group D was an unreinforced control. Fibers were positioned either around (A), beneath the notch (B), or at the disc base (C). Specimens were stored in distilled water at 37°C for 24 h before testing to failure (CHS=1mm/min) in a universal testing machine. Mean torque to failure values ranked [P< 0.05; one-way analysis of variance (ANOVA)] as follows A = B > C = D. In series II five groups of three unit bridges (n =5/group; codes A to E) were prepared from Artglass dental composite without (group A) or with (groups B to E) different Connect fiber reinforcement locations/ techniques. Bridges were cemented using 2 bond resin cement to a standardized substructure. After storage, as per series I, bridges were loaded mid-pontic region to failure. One-way ANOVA showed no significant (P=0.08) difference between test groups. The research hypothesis was that notched disc and 3 unit bridge test techniques would discriminate equally between fiber-reinforced specimens and an unreinforced composite control was rejected.

Wireless Networking for the Dental Office: Current Wireless Standards and Security Protocols
Authors: Mupparapu Muralidhar 
Published: July 2019

Abstract
Digital radiography has gained immense popularity in dentistry today in spite of the early difficulty for the profession to embrace the technology. The transition from film to digital has been happening at a faster pace in the fields of Orthodontics, Oral Surgery, Endodontics, Periodontics, and other specialties where the radiographic images (periapical, bitewing, panoramic, cephalometric, and skull radiographs) are being acquired digitally, stored within a server locally, and eventually accessed for diagnostic purposes, along with the rest of the patient data via the patient management software (PMS).1 A review of the literature shows the diagnostic performance of digital radiography is at least comparable to or even better than that of conventional radiography.2,3 Similarly, other digital diagnostic tools like caries detectors, cephalometric analysis software, and digital scanners were used for many years for the diagnosis and treatment planning purposes. The introduction of wireless charged–coupled device (CCD) sensors in early 2004 (Schick Technologies®, Long Island City, NY) has moved digital radiography a step further into the wireless era. As with any emerging technology, there are concerns that should be looked into before adapting to the wireless environment. Foremost is the network security involved in the installation and usage of these wireless networks. This article deals with the existing standards and choices in wireless technologies that are available for implementation within a contemporary dental office. The network security protocols that protect the patient data and boost the efficiency of modern day dental clinics are enumerated.

Evaluation of the Diagnostic Advantage of Intraoral D and E Film for Detecting Interproximal Caries
Authors: Davari Abdolrahim , Ardakani Fatemeh Ezoddini , Goodarzipour Daryoush , Goodarzipour Koorosh 
Published: July 2019

Abstract
Clinicians strive to reduce the exposure of patients to X-ray radiation in an effort to decrease its harmful effects on the body. A potential strategy for achieving this goal is the use of high-speed films that require less exposure to radiation to generate a diagnostic image. There are two film types commonly used in intraoral radiography: high speed or “Ekta-speed” film (Type E) and normal speed or Ultra-speed film (Type D). Type E film requires nearly half of the exposure time that is required by Type D films to produce an acceptable diagnostic image; however, the diagnosis quality and usability of these film types are under question.
The purpose of this research is to compare the diagnostic quality of Type E with Type D film when used to diagnose proximal caries. In this study 40 pairs of extracted maxillary premolar teeth were chosen and divided into four groups of 10 pairs. Cavities were made on proximal surfaces at different depths (0.5, 1, 1.5, and 2 mm) for each group. Bitewing radiographs were then taken on each pair of teeth using Type E film and then again using Type D film. Radiographs were evaluated by two oral radiologists and two operative dentistry specialists who recorded the perceived diagnostic depth of the prepared cavities.
Our data showed both Type D and E films are suitable for use in diagnosing proximal caries, and despite a minor discrepancy between them no significant difference was found with regard to their value in diagnosing proximal caries.

Authors: Evcil Mehmet Sinan , Çolak Meltem 
Published: July 2019

Abstract
The purpose of this study was to compare the surface pH level of four different type sealers after mixing at various time intervals in vitro. After cleaning and shaping root canals in 50 recently extracted, singlerooted human teeth, they were divided into six groups. Each of four groups was obturated with Apexit, N2, Sealapex, and Grossman sealers. The remaining groups served as controls. In group 1 nothing was added to the vial of saline solution. In group 2 canals had been instrumented but not obturated with sealer. The pH level of saline solutions was determined at intervals of 1 hour, 4 hours, 1 day, 2 days, 3 days, 1 week, and 4 weeks after teeth were placed in them. The pH levels of the five solutions were compared to each other and to that of saline solution only.

Published: July 2019

AbstractPeriodontal mucogingival techniques continually evolve. This provides the patient more treatment alternatives for common problems such as gingival recession. General practitioners should be familiar with these techniques in order to identify patients who might benefit from them. Currently, subepithelial connective tissue grafts (SCTG) remain the most reliable techniques used to cover denuded root surfaces. This paper reviews patient selection and the numerous surgical approaches for subepithelial connective tissue grafting.CitationSedon CL, Breault LG, Covington LL, Bishop BG.

Correlation of Different MRI Characteristics of Anterior Disc Displacement With Reduction and Without Reduction
Authors: Şener Sevgi , Akgünlü Faruk 
Published: July 2019

Abstract
The aim of this study was to evaluate the correlations between magnetic resonance imaging (MRI) findings in anterior displacement with reduction (ADDR) and anterior displacement without reduction (ADDWR). Two hundred patients with temporomandibular disorder (TMD) symptoms were examined clinically by a clinician experienced with this disorder. There were 130 joints with ADDR and 45 joints with ADDWR; 88 patients were identified according to the clinical and MRI diagnoses of both observers. The MRI characteristics such as position, signal intensity, morphology of disc, degenerative changes, effusion, scar tissue, avascular necrosis, and condylar hypermobility were evaluated in the individual with ADDR and ADDWR. The Chi-square test was used to determine the correlation between MRI characteristics in the ADDR and the ADDWR. There were significant relationships between degenerative changes and increased signal intensity, degenerative changes and side-way displacement, effusion and the deformation of the disc, effusion and subluxation, increased signal intensity and subluxation, elongation deformation and increased signal intensity, and elongation deformation and side-way displacement in ADDR. There were significant relationships between degenerative changes and effusion, degenerative changes and decreased signal intensity, scar tissue and avascular necrosis, deformation of disc and increased signal intensity, as well as deformation of disc and decreased signal intensity in ADDWR. These MRI findings also correlated with the clinical findings, however, this correlation appears to be a synergistic pattern rather than a set of clear-cut relationships. The correlations between these MRIs and different clinical findings such as pain and dysfunction also must be evaluated. Existing correlations must be considered in the diagnosis and treatment planning of TMD, and signs and symptoms of TMD should be monitored after treatment.

Effect of Direct Relining on Stresses at the Denture Base and the Metal Frame of Removable Partial Dentures
Authors: Al-Ghannam N.A. , Fahmi F.M. 
Published: July 2019

AbstractThe Kennedy Class I removable partial denture (RPD) can cause stress to supporting hard and soft tissues and may lead to harmful effects. The purpose of this study is to investigate the pattern of these stresses in three different positions before and following a relining procedure. Ten patients, five males and five females, with a lower distal extension RPD and an opposing upper class III type RPD were selected for this study. Strain gauges together with a strain gauge indicator were used to study the pattern of stresses in three selected positions. Some changes were significantly different at the site of the denture base and at the metal frame near the direct retainer. After relining, the stresses were shared partially by the abutments and partially by the tissues. Maximum stresses were reported during swallowing. No significant difference was noticed between males and females.CitationAl-Ghannam NA, Fahmi FM.

An Anterior Tooth Size Comparison in Unilateral and Bilateral Congenitally Absent Maxillary Lateral Incisors
Authors: Baidas Laila , Hashim Hayder 
Published: July 2019

Abstract
The purpose of this study is to compare the anterior tooth size width in patients with congenitally missing maxillary lateral incisors using the Bolton Index and divine proportion. The study sample consisted of thirty pairs of orthodontic models with unilateral (twelve patients; 7 females, 5 males) and bilateral (eighteen patients; 13 females, 5 males) absence of maxillary lateral incisors. The mean ages of the selected cases were 17.7 and 17.5 years, respectively. Descriptive statistics were used for the data analysis. The result showed the mean of the Bolton Index in cases with bilateral absence was closer to the Bolton mean than in cases with unilateral absence. In the unilateral absence cases the width of the existing lateral incisor (5.5 mm) was an average of 1.00 mm less compared to the standard mean (6.5 mm). The divine proportion showed the maxillary central incisors were small in width as indicated by the adjusted value or they were slightly larger in width than the mandibular central incisors. In cases with unilateral and bilateral absence the Bolton Index exhibited maxillary insufficiency, which was confirmed by evaluating the divine proportion of the maxillary and mandibular incisors. The result of the present study will be of great help to both the orthodontist, whether to open or close the space, and to the prosthodontist to restore the missing teeth of patients having missing maxillary lateral incisors.

Aneurysmal Bone Cyst of the Coronoid Process of the Mandible: A Case Report
Authors: Martins Wilson Denis , Fávaro Daniela Martins 
Published: July 2019

Abstract
A rare case of aneurysmal bone cyst (ABC) located in the ramus of the mandible with involvement of the coronoid process is presented. The pressure of the slow growing tumor apparently caused severe resorption of the zigomatic arch. Treatment consisted of enucleation of the tumor via a pre-auricular access. A two year follow-up showed restoration of facial symmetry and partial regeneration of the coronoid process. To our knowledge this is the second published case of an ABC of the coronoid process of the mandible.
