Adenoid Cystic Carcinoma of Nasal Septum: Report of Two Cases
Authors: Priya SR , Chaukar Devendra A , Cruz Anil KD' 
Published: January 2012

ABSTRACTWe present two cases of adenoid cystic carcinoma arising from the nasal septum. The first patient was previously untreated. The second patient had been operated outside with a presumed diagnosis of a benign lesion. We excised both the lesions with wide margins as is advisable for this histology. The histopathology examination in the first case showed adenoid cystic carcinoma with no high-risk features. In the second case, the histopathology revealed no residual malignancy. Adjuvant treatment was, therefore, not given to either patient. The postoperative appearance in both cases was good. They have been disease free on follow-up.

Published: January 2012

ABSTRACT

Background
The aim of this study was to evaluate the efficacy of intensive application of sodium fluoride varnish in prevention of caries in molars in children between 6 and 7 years and to evaluate the caries status in molars before and after application of fluoride varnish (Cavity Shield).

Materials and methods
Two hundred fifty children (6-7 years) randomized into varnish and control groups. Children in varnish group received fluoride varnish (Cavity Shield) three times during one week (once every 2 days). Clinical and radiographical examinations of all children were performed prior to the first application of varnish and 1 year later. For evaluation and comparison, all the collected data were subjected to statistical analysis.

Results
At the end of 1 year period, varnish group had 27.7% caries reversal in deciduous dentition which was statistically significant. Though there was a decrease in the caries increment in the permanent dentition, it was not statistically significant.

Conclusion
Application of fluoride varnish Cavity Shield three times once a week, once a year either in permanent or in deciduous dentition, is associated with substantial reduction in caries increment.

Clinical significance
Fluoride varnish can prove to be an effective tool in prevention of dental caries in both primary and permanent dentitions.

ABSTRACT

Objective
To determine the resistance failure value of nonprecious metal-ceramic restorations at the incisal edge with varying thickness under different application of load.

Materials and methods
An Ivorian central incisor was prepared to receive metal-ceramic crown, which was further duplicated, invested, casted and 72 metal dies were fabricated in Co-Cr alloy. Metal dies were relieved with die spacer, lubricated and wax patterns were prepared for metal copings, which were further invested and casted and 72 metal copings were fabricated. The ceramic materials were used for the study viz. Vita/VMK, IPSd SIGN, and superporcelain. Ceramic built-up was carried out according to manufacturer instructions. Incisal ceramic built-up was carried out with increasing thickness from 2.00 to 2.5 and 3.00 mm.

Results
A total of 72 samples, prepared for the study, were divided into two groups, i.e. group I (36 samples) and group II (36 samples), as per the direction of application of load. The samples were mounted on acrylic block (6 samples/block). A total 12 acrylic blocks were prepared. All the samples were tested using universal testing machine (MTS/USA). The load was applied with crosshead speed of 5 mm/min.

Conclusion
Fracture resistance was found to be highest for the 2.00 mm and lowest for 3.00 mm incisal ceramic thickness samples regardless of the ceramic material in both groups. There was a gradual decrease in fracture resistance as the incisal ceramic thickness increased from 2.00 to 3.00 mm in all samples. Fracture resistance was marginally higher for incisal ceramic build-up of 3 mm thickness on group II metal copings than on group I copings. Fracture resistance was highest for IPSd SIGN followed by that of Vita/VMK-95 and superporcelain.

Clinical significance
A 3.00 mm incisal ceramic thickness offered greater fracture resistance in comparison to lower values of incisal thickness; IPSd SIGN offered greatest fracture resistance followed by that of Vita/VMK-95 and superporcelain.

Authors: Shabzendedar Mahbobeh , Moosavi Horieh , Talbi Maryam , Sharifi Marjan 
Published: January 2012

ABSTRACT

Aim
The goal of the study was to evaluate the effect of caries removal by three various methods on the permeability of class II composite resin restorations in primary molar teeth.

Materials and methods
Forty-five recently extracted primary molars were randomly assigned to three groups for three different methods of caries removal; group 1-mechanical, group 2-caries detector dye, and group 3-Carisolv (n = 15). After that, class II cavities in all groups were restored with the adhesive (Opti Bond Solo Plus) that was applied according to the manufacturer's instruction and a posterior composite (Herculite XRV), which was used incrementally. After 24 hours the samples were thermocycled in water for 500 cycles between 5 and 55°C with a dwell time of 30 sec. Permeability was assessed by the fluid filtration method. The data were analyzed using the ANOVA test while study groups were compared with Tukey test for statistically significant differences at a 5% significance level.

Results
The evaluation of tested groups indicated that the highest (0.80) and least (0.37) mean of permeability was observed in group 2 and 3 respectively. Significant difference was revealed among the tested groups (p = 0.045). The comparison of Carisolv and caries detector dye groups indicated a statistically significant difference (p = 0.037). There was not any significant difference between Carisolv or caries dye in the conventional group.

Conclusion
Using the chemomechanical and staining methods for caries removal had no more detrimental effect on permeability than the conventional technique. However, caries detection dye for caries removal could be more harmful than chemomechanical method.

Clinical significance
None of the current caries-excavation techniques could eliminate permeability in class II composite resin restorations. Furthermore, staining methods do not have an adverse effect on sealing ability in comparison to the conventional technique.

Authors: Ghosh Gaurav , Jayaram Krithika M , Patil Rekha V , Malik Sangeeta 
Published: January 2012

ABSTRACTAimAltered lipid profile patterns have been associated with malignancies because lipids play a pivotal role in the maintenance of cell integrity. The present study evaluated alterations in serum lipid profile in oral squamous cell carcinoma patients as well as its association with the habit of tobacco consumption.Materials and methodsThe study included 30 oral squamous cell carcinoma patients, 20 patients with the habit of tobacco consumption and 20 controls. Serum lipids, including (i) total cholesterol, (ii) LDL cholesterol (LDLC), (iii) HDL cholesterol (HDLC), (iv) VLDL cholesterol (VLDLC) and (v) triglycerides, were analyzed by spectrophotometric kits.ResultsA significant decrease in serum total cholesterol (TC) levels, triglyceride levels (p = 0.007, p = 0.029 respectively) were observed in oral squamous cell carcinoma patients as compared to the healthy control group. The mean serum HDLC levels (p = 0.003) were significantly lowered in the tobacco habituates when compared to the healthy controls. The mean serum total cholesterol levels were significantly lower in subjects with oral squamous cell carcinoma (p = 0.000) as compared to the tobacco habituates. Likewise, LDLC levels and TC:HDLC ratios (p = 0.000 and p = 0.000 respectively) were significantly decreased in oral squamous cell carcinoma patients as compared to the tobacco habituates. Our data strengthens the evidence of an inverse relationship between serum lipid levels and oral squamous cell carcinoma.ConclusionThe lower level of serum cholesterol and other lipid constituents in the patients is thought to be due to their increased usage by tumor cells for new membrane biogenesis.Clinical significanceThe lower serum lipid profile status serves as a useful indicator for gauging initial changes occurring in tumor cells. A detailed study of the cholesterol carrying lipoprotein transport mechanisms helps in better understanding of the underlying mechanisms of the regulation of serum cholesterol concentrations in cancer.How to cite this articleGhosh G, Jayaram KM, Patil RV, Malik S.

Nonfluoride Caries-preventive Agents: New Guidelines
Authors: Pickett Frieda Atherton 
Published: January 2012

ABSTRACT
Nonfluoride caries-prevention agents have been developed and promoted to the dental profession in the recent past. The oral healthcare professional is encouraged to use evidence-based information when making clinical decisions. Recently, a systematic review was completed by a panel of experts convened by the American Dental Association Council on Scientific Affairs and recommendations were developed to address efficacy of nonfluoride agents in reducing the incidence of caries and arresting or reversing the progression of caries. The panel found that all nonfluoride agents should be used as adjuncts, following initial use of primary caries prevention strategies (fluoride, sealants, anticaries diet). This paper discusses the levels of certainty for evidence statements and clinical applications of these recommendations.

Clinical significance
The panel concluded that certain nonfluoride agents may provide some benefits as adjunctive therapies in children and adults at higher risk of developing caries.

Authors: Arslan Ahmet , Gursoy Hare , Cologlu Sedat 
Published: January 2012

ABSTRACTObjectiveIn this case report, treatment of lymphangioma (a red-purple vesicular apperance, nonulcerated lesion, located on the gingiva of the mandibular alveolar bone) with CO2 laser on a 63-year-old female patient and 2 years clinical outcome is presented.BackgroundLymphangiomas are hemorrhagic, rare, benign hamartomatous tumors of lymphatic system have a marked predilection for the head, neck and oral cavity. Lymphangiomas are congenital lesions and an often present at or around the time of birth (60%). Among the dental laser systems, CO2 laser is the most suitable instrument for the treatment of soft tissue pathologies because of its affinity for water-based tissues. The absorbed energy causes vaporization of the intra- and extracellular fluid and destruction of the cell membranes. A major advantage of the 10.600 nm wavelength CO2 laser is its ability to seal blood vessels during surgery and to make the excision of vascular lesions with its hemostatic effect.MethodsCO2 laser application (focused CO2 laser beam, 10.600 nm) was performed in a separate operation room at 3 watt (W), continous wave (CW) with 90 degree angle tip under local anesthesia. The mouth was protected from reflection of the laser by wet gauzes. The wound formed by laser was left open to secondary epithelization. Excessive bleeding was not observed during the procedure. The wound formed by laser was left open to secondary epithelization. Neither sutures nor dressings were used after surgery. Only paracetamol and chlorhexidine digluconate mouthwash were prescribed during the postoperative period. There was no postsurgical complaints from the patient.ResultsCO2 laser worked well while making the excision with its hemostatic effect. No recurrence was seen in the two years follow-up period.ConclusionCO2 laser therapy can be used as a primary alternative method in the treatment of lymphangiomas. It can be safely used and recurrence may be less than conventional excision with scalpel. However, long-term clinical follow-up is neccessary for the recurrence of the lesion.Clinical significanceCO2 laser treatment can be used safely in the treatment of lymphangiomas.How to cite this articleArslan A, Gursoy H, Cologlu S.

Authors: Singh Santosh K , Gupta Indra , Agarwal Rakesh K , Sharma Pranjal , Patil Raju U 
Published: January 2012

ABSTRACT
The traumatized primary teeth have a great clinical significance because it not only have consequences on itself but also on its succedaneous developing permanent teeth due to its close anatomical relationship. The extent of severity is adjudged by the type of trauma and the age of the child at the time of trauma. For instance, avulsion and intrusive injuries present with high percentage of developmental disturbances in permanent teeth than subluxation and extrusive injuries. When considering the age of the child at the time of trauma, consequences are less severe in children over 4 years of age than in the younger age group.

Clinical significance
It highlights the sequelae of trauma to primary teeth with the aim of aiding in detection of probable alterations in the traumatized primary teeth and its succedaneous permanent teeth.

SCIENCE AND SERENDIPITY IN POLYOLEFIN ELASTOMER DEVELOPMENT
Authors: Kresge Edward N. 
Published: January 2012

Abstract
Polyolefin elastomers based on ethylene, propylene, and isobutylene plus other monomers are now widely used in many diverse applications. Major research and development efforts have led to thermoplastic polyolefin soft automobile bumpers, modifiers for lubricating oils, and fast extrusion grades of ethylene–propylene–diene terpolymers. These and other successful commercial innovations depend on the tools of the basic science of structure–property relationships, proper needs assessments, sound engineering, and good management. These tools have been largely provided by my colleagues at ExxonMobil Chemical, customers, and universities and I thank them profoundly. Several historical commercial developments are discussed, including thermoplastic polyolefin elastomers based on ethylene–propylene copolymer–isotactic–polypropylene blends, shear stable viscosity modifiers based on ethylene–propylene copolymers, bimodal molecular weight and compositional distribution EPDM to control rheological characteristics, and diene structure and interchain distribution. In addition, the ongoing research on nanocomposites for tire innerliners based on isobutylene polymers and clay is reviewed. The roles of polymer science, serendipity, and lost opportunity costs on innovation are also discussed.

Published: January 2012

Abstract
Our objective is twofold: (1) to offer a short state of the art on the framework of configurational mechanics to rubber researchers and engineers, and (2) to show that it is well adapted to rubber mechanics. The state of the art presents the general theory but also highlights the physical meaning of the Eshelby stress tensor and of its path integrals; then, we propose a list of recent applications involving configurational mechanics. Attention is then focused on rubber applications: recent work on the simulation of fracture in inelastic materials and on the development of predictors for fatigue crack initiation is presented.
PATENTS OF CHARLES GOODYEAR: HIS INTERNATIONAL CONTRIBUTIONS TO THE RUBBER INDUSTRY
Authors: Calzonetti Jo Ann , Laursen Christopher J. 
Published: January 2012

AbstractCharles Goodyear is best known for a single patent, U.S. patent 3633, “Improvements in India Rubber Fabrics Vulcanization of Rubber” (1849). The story of Goodyear and his 1839 discovery of vulcanization, a method to increase the strength and resiliency of rubber, has been told in several well-researched accounts. What has not been accomplished is a compilation of the complete patents of Goodyear. Although many books and articles discuss the patents of Charles Goodyear, up to this point there was no single comprehensive and accurate list of his patents including all the information needed to retrieve the original documents from the issuing patent organizations. Librarians of the Rubber Division, American Chemical Society and the University of Akron, using both print and online resources, were able to compile a complete list of Goodyear's patents issued in the 19th Century.
Experimental Characterization and Constitutive Modeling of the Mechanical Properties of Uncured Rubber
Authors: Kaliske M. , Zopf C. , Brüggemann C. 
Published: January 2012

Abstract
The properties of uncured rubber are characterized by a viscoelastic material formulation in order to develop a finite element method (FEM) to predict the deformation behavior of this material during processing. As material formulation, a viscoelastic material model is considered, which consists of a nonlinear Hooke spring connected in parallel to a finite number of Maxwell elements. To identify the material parameters, various tests have to be conducted. The chosen test procedure and data analysis strategy are presented. An evolutionary optimization procedure is used to fit the material parameters to the measurements by minimizing the mean square error of the approximation. At the end, the suitability of the chosen material model and the identified material parameters is shown. Finally, the result of a molding test is compared to the corresponding FEM simulation.
Characterization of Polyurethane Formulations by Direct Probe Atmospheric Pressure Chemical Ionization Mass Spectrometry
Authors: Whitson Sara E. , Wesdemiotis Chrys , Lattimer Robert P. 
Published: January 2012

Abstract
Complex, commercially available polyurethane polymers were heated at slowly increasing temperatures on a direct probe (DP) inserted into an atmospheric pressure chemical ionization (APCI) source of a quadrupole ion trap mass spectrometer. Slow heating of the probe allowed for temporal separation of the thermally desorbed components (such as additives) and thermal degradation products, based on their volatilities and bond stabilities. In situ analysis of the released desorption products and pyrolyzates was accomplished by APCI mass spectrometry. DP-APCI enabled the characterization of polyurethanes that cannot be analyzed directly by mass spectrometry. Distinctions could be made between polymer formulations with variable physical properties due to their different blends.
