Published: July 2019

Abstract

Aim
The objective of this report is to describe the implementation and pilot-test of an integrated wireless local area network (WLAN) system that incorporated the Planmeca Promax® CCD based digital panoramic/ cephalometric x-ray system, Dolphin® software, and multiple remote user units to increase the efficiency of data management by the residents in the Department of Orthodontics.

Background
The Department of Orthodontics of the New Jersey Dental School (NJDS) acquired the Dolphin® cephalometric analysis software and the Planmeca Promax® digital panoramic/cephalometric x-ray units on separate occasions. Dolphin has been in use for many years at this institution, the current version being 10, and the Promax was acquired in the Fall of 2002. The digital panoramic and cephalometric radiographs were acquired and stored separately in the Planmeca's Dimaxis database.

Report
During the incorporation of the WLAN, there was an opportunity to research and install the best available security system for the WLAN so it could be a network model for the other departments within the dental school and perhaps other dental schools around the nation.

Summary
Digital radiographs, once obtained, can be stored locally or transmitted securely to remote locations via a local area network. This article describes the selection criteria and methodology that would optimize the transmission and retrieval of such images instantaneously on demand at chair side locations. This will not only save significant clinical time but will enhance the productivity of the clinic in the long run.

Published: July 2019

Abstract

Aim
The aim of this study was to investigate the influence of light curing method, composite shade, and depth of cure on composite microhardness.

Methods and Materials
Forty-eight specimens with 4 mm of depth were prepared with a hybrid composite (Filtek Z-100, 3M ESPE); 24 with shade A1 and the remaining with shade C2. For each shade, two light curing units (LCUs) were used: a quartz-tungsten-halogen (QTH) LCU (Optilight Plus - Gnatus) and a light emitting diode (LED) LCU (LEC 470 II - MM Optics). The LED LCU was tested using two exposure times (LED 40 seconds and LED 60 seconds). After 24-hour storage, three indentations were made at mm depth intervals using a Knoop indenter. Data were submitted to three-way analysis of variance (ANOVA) and Tukey's test (p<0.05).

Results
The three factors tested (light curing method, shade, and depth) had a significant influence on the composite microhardness (p<0.05). All groups presented similar hardness values in the first mm, except for composite shade C2 cured with LED for 40 seconds. The hardness decreased with depth, especially for shade C2 for 40 seconds. Increasing light-curing time with LED produced hardness values similar to the QTH.

Conclusions
The light curing method including variations of time, the depth of cure, and the composite shade influence the composite microhardness.

Clinical Significance
Clinicians should avoid thicker increments when working with composite restorations. Extended light-curing time might be indicated depending on the composite shade and on the light-curing device.

Authors: Gupta Siddharth , Bhowate Rahul , Degwekar Shirish S. 
Published: July 2019

Abstract

Aim
The aim of this report is to present the intraoral and extraoral clinical features of a young female patient with tuberous sclerosis complex (TSC) who exhibited multiple hamartomas of various organ systems including a fibromatous growth on the gingiva.

Background
TSC is a rare neurocutaneous syndrome exhibiting multiple hamartomatous proliferations that may involve multiple organs such as the brain, kidney, heart, eyes, lungs and skin. Oral manifestations such as enamel pitting and fibromatous growth of the gingiva are commonly seen in patients with TSC.

Report
A 16-year-old female patient presented with a painless interdental gingival growth in the maxillary left incisor and canine region that bled occasionally. Associated findings were adenoma sebaceum (angiofibromas) on the face, a Shagreen patch on the lumbosacral region, ash leaf spots on the trunk, and subangual fibromas (Koenen's tumor) on the nails of fingers and toes. The final diagnosis of TSC was made on the basis of the clinical findings of the skin, computerized tomography (CT) findings of the brain and kidney, ultrasonographic findings of kidney, and a histopathologic evaluation of the gingival growth which met the major and minor criteria required for a diagnosis of TSC.

Summary
This case report is a good example of the complex nature of patients with TSC. The diagnosis and management of these patients varies depending on the specific presentation of the disease. Dentists need to be mindful of the systemic issues as well as oral conditions related to this disease. Dental practitioners are advised to work closely with the patient's physician during treatment.

Published: July 2019

Abstract

Aim
The purpose of this in vitro study was to analyze the antimicrobial activity of root canal sealers by using the agar diffusion test (ADT).

Methods and Materials
Three categories of root canal sealers were included in the study: resin-based sealers (4), zinc oxide-based sealers (3), and calcium hydroxide-based sealers (2). The microbial strains used were: S. aureus (2 strains), C. albicans (2 strains), and E. faecalis (1 strain). Statistical analysis was conducted using a one-way analysis of variance (ANOVA). Tests of differences were analyzed using the Tukey's test with a value of p < 0.05 considered statistically significant.

Results
The antimicrobial activity of root canal sealers was ranked in descending order as follows: Sealite Regular, Cortisemol, Dentalis KEZ, AH26, Sealapex, Acroseal/Topseal, and Endorez/AH plus.

Conclusion
Root canal sealers showed different inhibitory effects depending on their types and the bacterial strains tested. Root canal sealers containing formaldehyde and eugenol proved to be effective against the microorganisms studied.

Clinical Significance
The incorporation of antimicrobial components into root canal sealers may become an essential factor in preventing the re-growth of residual bacteria and control of bacteria re-entry into the root canal system.

Authors: Aminabadi Naser Asl , Farahani Rmain Mostofi Zadeh , Gajan Esrafil Balayi 
Published: July 2019

Aim
The aim of this clinical investigation was to determine the efficacy of distraction and counterstimulation in the reduction of pain during the administration of local anesthetics in pediatric dental patients.

Methods and Materials
A total of 78 healthy children (male: 40, female: 38) ages four to five years (mean age: 4.72 years old) without any history of previous intraoral injection were included in the present study. The subjects had at least one carious primary molar. The subjects were randomly allocated into three groups. Group SA received topical anesthesia followed by an inferior alveolar nerve block (simple anesthesia). Group C+SA received counter stimulation using intraoral and extraoral finger vibration in addition to the Group SA protocol. Group CD+SA incorporated verbal distraction in addition to topical and local anesthesia and counterstimulation. A sound, eye, and motor (SEM) scale was used for quantification of pain reaction. Data were analyzed using an analysis of variance (ANOVA).

Results
The SEM values for Groups SA, C+SA, and CD+SA was 8.25, 5.07, and 3.41, respectively. According to the SEM scale a severe pain reaction was observed in Group SA but not in the other groups. The pain reaction for Group SA was significantly higher than the two other groups (P<0.05). Moreover, the subjects in Group CD+SA exhibited significantly less pain compared to those in Group C+SA.

Conclusion
Both distraction and counterstimulation are effective in reducing pain reaction in a clinical setting. However, it may be more plausible to use both techniques simultaneously to achieve more favorable results with reference to a reduced pain reaction in pediatric dental patients.

Authors: Korkmaz Yonca , Attar Nuray , Ozalp Meral 
Published: July 2019

Aim
The aim of this study was to evaluate the antibacterial effects of different one-step and two-step selfetching primer/adhesives on Streptococcus mutans (S. mutans), Lactobacillus casei (L. casei), and Lactobacillus acidophilus (L. acidophilus).

Methods and Materials
The antibacterial effects of Clearfil Protect Bond Primer and Bonding agent; AdheSE Primer and Bonding agent; Adper Prompt L-Pop; Futurabond NR; Clearfil Tri S Bond; and Cervitec (positive control, 1% chlorhexidine varnish) were tested against standard strains of S. mutans, L. Casei, and L. acidophilus using the disk diffusion method. Standard filter paper disks (n=5) impregnated with 20 microL of each material were prepared. After incubation at 37°C for 48 hours in a 5-10% CO2 atmosphere, the diameter of inhibition zones were measured in millimeters. Data were analyzed using one way analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA). Duncan's Multiple Range Test was used for pairwise comparison.

Results
The size of inhibition zones produced by primer/adhesives varied among the brands. AdheSE Primer: S. mutans (20.6±1.51); L. casei (14.8±1.78); L. acidophilus (11.4±0.54). Adper Prompt L-Pop: S. mutans (19.6±1.51); L. casei (13.8±1.64); L. acidophilus (13.8±1.09). Cervitec: S. mutans (23±0.00); L. casei (27±0.70); L. acidophilus (22.4±0.54). Clearfil Protect Bond Primer: S. mutans (17±0.00); L. casei (17.6±0.54); L. acidophilus (22.4±0.54). Futurabond NR was found effective only against S. mutans (14.6±1.67). Of all the materials tested, AdheSE Bonding agent, Clearfil Protect Bond Bonding agent, and Clearfil Tri S Bond exhibited no inhibition zone (-) for all bacteria tested.

Conclusion
Among the adhesives tested Clearafil Protect Bond Primer based upon monomer methacryloyloxydodecylpyridiniium bromide (MDPB) was found to be the most potent material against L. acidophilus and L. casei. AdheSE Primer and Adper Prompt L-Pop are highly effective against S. mutans.

Clinical Significance
Compared with other adhesive systems, Clearfil Protect Bond Primer (containing MDPB) showed a high antibacterial effect against all microorganizms tested. Two-step, self-etching primer/ adhesive system Clearfil Protect Bond might be a suitable choice under minimally invasive restorations. The recently developed one-step, self-etching system Clearfil Tri S Bond showed no antibacterial effect against microorgazims tested.

Authors: Ozel Emre , Korkmaz Yonca , Attar Nuray 
Published: July 2019

Abstract

Aim
The aim of this in vitro study was to investigate the cervical microleakage and internal voids of nanocomposites comparing them with a hybrid composite in Class II restorations with the margins located coronal and apical to the cementoenamel junction (CEJ).

Methods and Materials
Standardized MOD cavities (one cervical margin located in dentin, one in enamel) were prepared in 40 extracted human molars and divided into four groups according to the composite used to restore them (n=10/group). Group 1: Adper Single Bond2/Filtek Supreme XT; Group 2: Excite/Tetric EvoCeram; Group 3: Prime & BondNT/Ceram X; and Group 4 (control) Adper Single Bond2/Filtek Z250. Groups were further divided into subgroups A and B. The “A” subgroups represent the level of the location of the cervial margin at 1 mm coronal to the CEJ, and the “B” subgroups represent the level of the cervical margin located 1 mm apical to the CEJ. After restoration of the cavities with nanocomposites, thermocycling, and immersion in 0.5% basic fuchsin, the dye penetration and internal voids were evaluated under a stereomicroscope. Data were analyzed with the Mann-Whitney U and Kruskal-Wallis tests with the Bonferroni correction for microleakage and with the Chi-square test for internal voids (p<0.05).

Results
The microleakage in the A subgroups was statistically significantly lower then B subgroups (p<0.05). No statistically significant difference was observed in terms of interface, cervical, and occlusal voids for all groups (p>0.05). No significant difference was observed between each group for three voids in all groups (p>0.05).

Conclusion
The location of the gingival margin affects the microleakage of nanocomposites but has no significant affect on the internal voids.

Clinical Significance
Gingival margin located 1 mm coronal to the CEJ provided a reduction in cervical microleakage in nanocomposite restorations.

ABSTRACT
Terror is a Latin word which means to frighten. Terrorism usually refers to killing of innocent people by antisocial groups with the vested interest of their own. Terrorism is practiced by collecting people from different regions, religions, of different age groups, by keeping objectives like social, economic or political. Sometimes terrorists stop or discriminate their activities once they achieve their goal. Bioterrorism is the intentional use of biological agents or their products to cause harm. Sometimes such attacks might be done to create a publicity or media spectacle. It is the unlawful use of force and violence against people. Biological weapon can strike suddenly without any warning and cause hazardous effects for longer duration. The effectiveness of the attack not lies in the act itself but also in the reaction of public and Government. Delivery of the biological agents can be through letters, parcels, toys, food items, books or anything. It is easy for bioterrorist to transfer the agents through these media or environment.

Authors: Juneja R , Kumar V , Bansal S 
Published: July 2019

ABSTRACT
Tooth loss, especially in anterior region, precipitates psychological distress to the affected individual. Providing an immediate definitive restoration is sometimes not possible and, in some specific clinical situations, a delay of few months may even be desirable before providing a final restoration. Natural tooth pontic is a simple and time-saving alternative for interim rehabilitation in anterior tooth region which restores the esthetics to near normal in a single appointment. This article discusses two cases where it was not possible to place an implant or any other definitive prosthetic restoration in immediate future. Excellent esthetic results were obtained with natural tooth pontic used as an interim restoration in these cases.

A Comparative Evaluation of Tensile Bond Strength and Hybrid Layer of Three Generation Bonding Agents by Scanning Electron Microscope (An In-vitro Study)
Authors: Dhawan Rajan , Indira R , Dhawan Shivani 
Published: July 2019

ABSTRACT
This study was done to compare the tensile bond strength of three different generation bonding agents to dentin using one composite resin and scanning electron microscopic study (SEM) of hybrid layer.
In this study 36 non carious human molar teeth were selected. 30 teeth were used for evaluating tensile bond strength and were divided in to three groups. Six teeth were used for hybrid layer evaluation also divided into three groups. Group 1 specimens 10 teeth were etched with 37% phosphoric acid and Scotch bond multipurpose adhesive was applied. Group 2 specimens 10 teeth were etched with 37% phosphoric acid and 3M Single bond was applied. Group 3 specimens 10 teeth were treated with Prompt-L-Pop. Composite material (3M- Hybrid-Z100) was applied incrementally and cured for 40 seconds each. Specimens were then stored in distilled water before testing. Two teeth from each group were cross-sectioned to obtain 1mm thick dentin disks for SEM evaluation. Adhesives were applied as mentioned above. Composite was applied over these discs and light cured for 40 seconds. Samples were stored in distilled water at 37°c for two weeks; these disks were fractured with chisel for cross-sectional viewing
Dentin conditioning with single bond (5th Generation) revealed better bond strengths as compared to scotch bond multipurpose (4th generation) and Prompt-L-Pop (6th generation). SEM evaluation of hybrid layer reveals that Single bond has shown a thicker hybrid layer comparing to other adhesives.
