Sino-orbital Aspergillosis: A Case Report and Brief Review of Literature
Authors: Kotrashetti SM , Neeli Arati S , Vallavan Ponni 
Published: January 2013

ABSTRACT
Aspergillosis of head and neck region primarily affects the nose and paranasal sinuses. Any type of paranasal aspergillosis may progress to more aggressive disease illustrating the importance of early recognition of this increasingly encountered disease. The invasive and in particular, the fulminant forms are associated with high mortality. We report a case of invasive aspergillosis of right maxillary sinus and orbit in an immunocompetent individual, along with a critical review and update of the literature. The patient underwent surgery for the debridement of right maxillary sinus through a Caldwell-Luc approach and drainage of orbital abscess as well followed by intravenous therapy of amphotericin B. Recovery with reduction of all the signs and symptoms was seen after 38 days from the appearance of first symptoms. Successful treatment of aspergillosis requires prompt diagnosis and rapid institution of therapy, because delay or nonaggressive therapy can result in the spread of infection with lethal consequences.

Authors: Patil Ravi B , Nagaraj Tejavathi , Patel Vinit B 
Published: January 2013

ABSTRACT

Aim
To evaluate the in vitro antimicrobial activity of three commercially available intense sweeteners against two common periodontal pathogens Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans.

Materials and methods
Three commercially available intense sweeteners namely saccharin, aspartame and sucralose were obtained and powdered. Necessary concentrations of the sweeteners were prepared by mixing them with an inert solvent. The antimicrobial efficacy was assessed using agar well diffusion technique. Statistical analysis was done using one-way ANOVA followed by Tukey's post hoc test. p-value < 0.05 was considered statistically significant.

Results
All the three sweeteners showed significant antimicrobial activity against the periodontal pathogens tested. Sucralose containing sucralose showed maximum zone of inhibition, against Aggregatibacter actinomycetemcomitans. Saccharin and aspartame containing saccharin and aspartame respectively, showed maximum zone of inhibition, against Porphyromonas gingivalis.

Conclusion
All the sweeteners used in this study have demonstrated significant antimicrobial activity. Therefore, these sweeteners could be recommended as an ideal alternative to sucrose.

Clinical significance
Dental caries and periodontal diseases are ubiquitous diseases of mankind caused by microorganisms. Dental caries is caused by sucrose. By altering the source like intense sweetener we can combat caries as well as with its antimicrobial properties against periodontopathic bacteria, we can reduce prevalence of periodontal diseases.

A Comparative Study of Different Bleaching Agents on the Morphology of Human Enamel: An in vitro SEM Study
Authors: Uthappa Roshan , Suprith ML , Bhandary Shreetha , Dash Sumit 
Published: January 2013

ABSTRACT
The purpose of the study was to compare two different commercial bleaching agents, Opalescence with Colgate Platinum, and 30% phosphoric acid used as aggressive agent on the morphology of human enamel.

Materials and methods
Ten freshly extracted, noncarious, human maxillary central incisors extracted for periodontal reasons were used in this study. The labial surface of the disinfected teeth were polished using a polishing paste with the help of rubber cup and a slow speed handpiece. Each tooth was sectioned at cement-enamel junction and the crown was separated into four specimens, all taken from labial surface. Group 1 was treated with Colgate Platinum for 7 hours, group 2 with Opalescence for 7 hours, group 3 was treated with 30% phosphoric acid for 30 seconds and group 4 was untreated and used as control. After the treatment period, the specimens were washed with normal saline and stored in sterile bottle and sealed. Photomicrographs obtained from the scanning electron microscopy (SEM) after surface treatments were examined for no alteration, slight alteration, moderate alteration and severe alterations.

Results
The specimens treated with commercial bleaching agents revealed no enamel surface morphologic alterations compared to control group. The specimen treated with phosphoric acid showed severe alterations.

Conclusion
Ten percent carbamide peroxide evaluated in this study does not etch tooth enamel or alter enamel surface morphology as do conventional etching techniques.

Clinical relevance
Carbamine peroxide is a safe and effective tooth whitening agent even when used for extended period of time. The enamel surface remains smooth which reduces caries due to plaque collection.

Authors: Prakash Sandeep , Nayak Rashmita , Choudhury Gopal Krishna , Deshpande Sumit , Ashok KP , Spoorthi BR 
Published: January 2013

ABSTRACT

Objectives
To correlate the changes in the level of female sex hormones (progesterone, estrogen) in plasma with the changes in severity of gingivitis in various trimesters of pregnancy till the postparturition.

Materials and methods
This study comprised of 20 pregnant women with good oral hygiene who were followed up in each trimester till 3rd month of postpartum by screening their oral hygiene status following OHI-S index by Greene and Vermillion. Clinically to correlate gingivitis, gingival index by Loe and Sillness was carried out in each trimester till postpartum. For hormonal assay, blood sampling by venipuncture was done and quantative analysis of the hormones was done by ELISA test.

Results and conclusion
The severity of gingivitis gradually increased and reached its peak in 3rd trimester followed by sudden decline in the severity in postpartum which correlated with gradual increase in the plasma level of progesterone and estrogen levels to reach their peak in the 3rd trimester and sudden fall after the postpartum. This study shows the role of female sex hormones in aggravating gingivitis to its peak in the 3rd trimester, even though the oral hygiene remains fairly good constantly.

Clinical significance
This study signifies the gingivitis status during different trimesters of pregnancy and postpartum indicating the general practitioner to take appropriate oral hygiene measures.

A Comparative Evaluation of Curing Depth and Compressive Strength of Dental Composite Cured with Halogen Light Curing Unit and Blue Light Emitting Diode: An in vitro Study
Authors: Divyashree R , Gururaj M , Kumar CN Vijaya , Paul Joseph , Krishnaprasada L 
Published: January 2013

ABSTRACT

Purpose
To evaluate the curing depth and compressive strength of dental composite using halogen light curing unit and light emitting diode light curing unit.

Materials and methods
Eighty cylindrical composite specimens were prepared using posterior composite P60(3M). Forty specimens, out of which 20 samples (group A) cured with halogen light and 20 samples (group B) cured using light emitting diode (LED) light were checked for curing depth according to ISO 4049. Remaining 40 samples out of which 20 samples (group I) cured using halogen light and 20 samples (group II) cured using LED light were checked for compressive strength using Instron universal testing machine.

Results
Twenty samples (group A) cured with halogen light showed better curing depth than 20 samples (group B) cured with LED light. Twenty samples (group I) cured with halogen light showed almost similar results as 20 samples (group II) cured with LED light for compressive strength.

Conclusion
Halogen light commonly used to cure composite resin have greater depth of cure, when compared to LED light, while both the lights produced compressive strength which is almost similar.

Clinical significance
Lower depth of cure with the LED unit, compared to the QTH unit, is associated with different light scattering due to differences in spectral emission. LED technology differs from QTH by the spectral emission that favorably matches the absorption spectrum of camphorquinone.

Authors: Rao N Venugopal , Naidu D Lakshmayya , Bharat JSV , Reddy M Venugopal , Naveen P 
Published: January 2013

ABSTRACT

Aim
This study is to evaluate the role of 1:1 v/v 30% trichloromethane and monomer solvent in enhancing the durability of bonding between cross-linked acrylic teeth and different heatcured denture bases with or without mechanical preparations made on ridge lap portion of the artificial teeth.

Materials and methods
Two high impact denture base resin materials (Trevalon HI, DeTrey, UK, and DPI Tuff, Mumbai) and one nonhigh impact denture base resin material (DPI Quick Set, Mumbai) were selected to form three groups. Each group contains 30 specimens prepared by five different methods. A mixture of 30% trichloromethane and monomer, mixed in the ratio of 1:1 and applied for 1 minute on the ridge lap area of experimental specimens of methods—B, C, D and E (Specimens of method—A being control group, where no alterations were made at the ridge lap portion of acrylic teeth) before curing. Hounsfield universal testing machine is employed to evaluate the comparative bond strengths.

Results
No significant difference was seen in bond strengths between specimens of experimental methods in all groups. When each group was assessed separately method B specimens in group 1 (739.2 N), group 2 (758 N) and method D specimens in group 3 (729 N) showed highest mean bond strengths. Control group specimens showed the least bond strength (400-460 N) in all groups with more adhesive failures.

Conclusion
Ridge lap portion of the specimens treated with chemical solvent as in method B showed increased bond strength in groups 1 and 2. Hence, this is a preferred method.

Clinical significance
Evaluation of effect of different chemical and mechanical preparations at the ridge lap areas of acrylic teeth before acrylization helps the clinician and technician to overcome the problem of debonding of teeth from denture bases and in turn provides better quality prosthesis to the patient.

Published: January 2013

ABSTRACT

Objective
This study was undertaken to assess the level knowledge and experience about CPR among oral and maxillofacial surgeons.

Materials and methods
In a cross-sectional study, a total of 96 professionals (31-PGs, 65-MDS staff) were surveyed using a self-administered structured questionnaire pretested through a pilot survey. The data was analyzed using the SPSS version 15.0. The Student's t-test and ANOVA test were used as test of significance. The level of significance was set at p ≤ 0.05.

Results
In the present study, 78% of oral surgeons had received training about CPR but only 52.0% have proper practical knowledge of performing it. As there were some cases due to CPA in dental practice even then half of the participants take history of patients regarding this. A significant difference was found according to designation with PGs having lower mean scores. A positive linear correlation was found between years of experience and knowledge about CPR (Pearson's correlation, r = 0.613, p = 0.00).

Clinical significance
The present findings showed that practical knowledge of performing CPR is still low and half of them still do not take history regarding this. So there is need for more knowledge about CPR through CDE programs.

Published: January 2013

ABSTRACT
Hereditary gingival enlargement also known as gingivitis or familial elephantiasis is a rare type of gingival enlargement. It appears as an isolated autosomal dominant disorder or maybe associated with other conditions. Oral manifestations may vary from minimal involvement of only tuberosity area and the buccal gingiva around the lower molars to a generalized enlargement inhibiting eruption of the teeth. This paper discusses the case of a 13-year-old female patient with distinctive facial characteristics who presented to the department with a chief complaint of swollen gums since 1 year. She had severe diffuse gingival enlargement of the maxilla and mandible. Diagnosis was made based upon clinical examination and family history. Quadrant wise internal bevel gingivectomy procedure was done for the patient to restore her functional and esthetic needs.

Published: January 2013

ABSTRACT
Condylar hyperplasia (CH), as the name suggests, affects mandibular condyle producing overgrowth of condyle, which is characterized by a slowly progressive, usually unilateral enlargement of the mandible, facial asymmetry and deviation of chin to the unaffected side. The condition is known to be selflimiting, usually begins around puberty, but may not be recognized until later in life. This paper reports a case of severe facial asymmetry secondary to CH, which was successfully treated by high condylectomy only.

Published: January 2013

ABSTRACT
Adenoameloblastoma or adenomatoid odontogenic tumor (AOT) is an uncommon, benign, epithelial lesion of odontogenic origin. It is a rare benign odontogenic tumor of the jaw affecting mostly young individuals with predominance in female. It occurs mostly in maxillary anterior region. On the basis of clinical and radiographical picture, it is often misdiagnosed as an odontogenic cyst.
We report on a rare case of a 13-year-old male patient with a follicular variety of AOT in mandibular left anterior region which is unusual for the same. Clinically and radiographically, the lesion was mimicking as a dentigerous cyst. Later surgical enucleation was done and specimen was sent for microscopic examination and was diagnosed as AOT along with a dentinoid-like deposits which is a rare finding.

Published: January 2013

ABSTRACT
Soon after tooth extraction the bone resorption takes place reducing the height and width of alveolar ridge. This produces an altered morphology of the bone unfavorable for implant placement and implant placement becomes impossible without surgical correction. Socket grafting maintains and preserves ridge for implant placement.

Authors: Zhou Jiahua , Yang Yang , Yin Xueyan , Xu Yong , Cao Yang , Xu Qian 
Published: January 2013

Purpose To investigate the production of bile duct endothelial cells via directed differentiation of porcine bone marrow mesenchymal stem cells (BMSCs) down the hepatic lineage in vitro and the biocompatibility of differentiated bile duct endothelial cells with electrospun nanofibers. Methods Porcine BMSCs were differentiated in vitro into bile duct endothelial cells, which were identified by morphology and RT-PCR. PLGA nanofiber membranes were prepared by electrospinning. The morphology was detected by scanning electron microscopy and the short-term (two weeks) in vitro degradation rate was determined. Adhesion and proliferation of the bile duct endothelial cells on the nanofiber surface were analyzed by calculating the cell adhesion rate and MTT assay, respectively. Cell growth, morphology and distribution on the material surface were observed by fluorescence staining and scanning electron microscopy, respectively. Results After four weeks of directed differentiation of BMSCs in vitro, cells showed the typical morphology of dendritic bile duct endothelial cells and had the expression of CK19. Scanning electron micrographs showed that electrospun materials were continuous nanofibers with diameters between 200 and 500 nm. No significant degradation of the PLGA nanofibers was observed within two weeks. Based on the measured cell adhesion rate, MTT assay, fluorescence staining, and scanning electron microscopy, the differentiated cells possess a good proliferative capacity on PLGA nanofibers. Conclusions BMSCs can be differentiated into the bile duct endothelial cells in vitro. Materials prepared by the electrospinning method have a nanofiber structure, which does not significantly degrade within two weeks. Differentiated cells exhibit good biocompatibility with the nanofibers.
