Treatment outcome of unilateral condylar fractures surgical versus conservative approach |
p. 8 |
Vijay Ebenezer, Balakrishnan Ramalingam The aim of this study was to compare the outcome of surgical and conservative approaches for the management of displaced unilateral condylar fractures. Twenty-seven patients who reported to our department within a period of two years (2008-2009) were included in our study. All patients selected for the study had unilateral and displaced condylar fractures, with a ramus shortening of more than 3 mm on the fractured side. The 6-month postoperative radiographs were compared and evaluated. Postoperative ascending ramus height was measured on orthopantomograms. The difference obtained between the closed and conservatively treated patient group was evaluated. Occlusion, postoperative mouth opening and lateral excursive movements were included as the other parameters for the comparison. Our small population study concluded that open reduction and fixation of displaced condylar fractures yielded good postoperative results when compared to the conservatively managed patient group. |

Bilateral keratocystic odontogenic tumor of mandible |
p. 12 |
BK Yashoda Devi, N Rakesh, V Aarthi Nisha, Parimala Sagar, Kavitha Prasad Odontogenic keratocyst (OKC) is one of the most common critical cysts of the oral cavity due to its aggressive behavior and high rate of recurrence. Recently studies prove that this lesion behaves like a tumour both in clinical presentation and histopathology, hence the term was recoined as keratocystic odontogenic tumor. The lesion often involves the jaws extensively and when they are present bilaterally, Gorlin-Goltz syndrome is suspected. The diagnosis should be solely based on histopathological confirmation and computed tomography (CT) can be used as an adjunct to estimate the size, extent and effects on its adjacent structures. Herein, we report a case of bilateral keratocystic odontogenic tumor in a 32-year-old male, which was diagnosed by a series of investigations and treated appropriately. |

EGFR and MEK pathway independent constitutive activation of ERK-1/2 in a serum starved oral squamous cell carcinoma cell line |
p. 15 |
Arvind Ramanathan The EGFR/Ras/RAF/MEK/ERK pathway is a major pathway involved in the control of growth signals, cell survival and differentiation. Constitutive activation of ERK-1/2 has been reported in cancers and has often been associated with constitutively active upstream activating signals. To understand the mechanism of activation of ERK-1/2 in oral squamous cell carcinoma (OSCC) we analyzed two cell lines, OSCC-1 and OSCC-2. OSCC-1 expressed physiological level of EGFR, while OSCC-2 had amplified copies of EGFR in the genome and hence overexpressed EGFR protein. Western blot analysis of the cell lysates showed constitutive activation of ERK-1/2 in both cell lines. In OSCC-2 cells, this activation of ERK-1/2 was associated with constitutive activation of upstream molecules - MEK-1/2 and EGFR, whilst in OSCC-1 this was independent of the activation status of MEK or EGFR. Thus, in this study we showed for the first time that the constitutive activation of ERK-1/2 in OSCC may occur independent of upstream activators. |

Comparative evaluation of resin tag formation on dentin substrate using one-step and two-step self etching system |
p. 21 |
Sushil Kumar, VG Sukumaran, A Subbiya, P Vivekanandhan, V Prakash An evaluation of length and depth of resin tag infiltration was done using four different bonding agents grouped as follows: Group I: 'One-bottle one-step' self-etch adhesive (i-bond, kulzer), Group II: 'Two-bottle one-step' self-etch adhesive (Adper prompt, 3M), Group III: 'Two-bottle two-step' self-etch adhesive (AdheSE, Vivadent) and Group IV: 'Etch and rinse' adhesive (Prime and bond NT, Dentsply). The study was conducted using 60 noncarious freshly extracted premolars solely extracted for orthodontic purpose. A standard smear layer was produced by using a wet 600-grit silicon carbide paper to simulate clinical conditions and later the bonding agents applied as per the recommended protocol. Each bonded sample was vertically sectioned to expose the resin-dentin interface to be observed under confocal laser scanning microscope and later images were analyzed using the Ultima Master Program version 4.15. The results were tabulated and statistically analyzed using one-way ANOVA and multiple range tests by Tukey-HSD procedure. |

Recurrent chronic suppurative osteomyelitis: Review of literature and report of a case |
p. 29 |
Ramakrishna Shenoi, Vrinda Kolte, Samprati Badjate, Vishakha Devrukhkar Chronic suppurative osteomyelitis (CSO) of the mandible is often considered difficult to treat and may lead to refractory osteomyelitis. This case report describes the successful surgical treatment of CSO of the mandible in a 65-year-old man. Combined surgical and antimicrobial therapy was used to cure CSO of the mandible. |

Gingival abscess revisited |
p. 33 |
SC Chandrasekaran, V Bagavad Gita, P Preethi Aim: The aim of the present article was to critically evaluate the available literature regarding gingival abscess and highlight a case report. Background: Abscesses are one of the main causes for patients to seek emergency care in the dental clinic. This condition has clinical implications, not only diagnostic, but also, prognostic and therapeutic, in everyday periodontal practice. Case description: This case report especially highlights the prevalence of the use of inappropriate aids to remove impacted food. Conclusion and clinical significance: It becomes necessary that we bear this basic fact in mind when we come across such periodontal emergencies before we arrive at a conclusive diagnosis. |

p. 37 |
Venugopal Naveenkumar, Saravanan Poorni, Dasarathan Duraivel, Rajamani Indira Molars demonstrate considerable anatomic complexities and abnormalities with respect to number of roots and root canals. This report presents, relatively uncommon clinical cases of maxillary and mandibular second molars with single root and single canal along with substantial data on the incidence of single canal in this tooth. |

Finite element method in orthodontics |
p. 40 |
N Raj Vikram, Y Mohamed Hashir, MK Karthikeyan Finite element analysis (FEA) is a commonly applied experimental research technique which enables us to study the effects of geometrical and material variations under load and internal mechanical process. In the last decade the application of a well-proven predictive technique, the finite element method (FEM), originally used in structural analysis has revolutionized dental biomedical research. |

Mineral loss before and after bleaching and mineral uptake on application of remineralizing agent |
p. 47 |
Poornima Jose, Malathi Suresh, S Kavitha, S Mahalaxmi The use of tooth bleaching agents has increased recently, with carbamide peroxide being most commonly used. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is a nanocomplex of calcium, phosphate and hydroxyl ions stabilized by phosphopeptides. This agent is commonly used for the remineralization of enamel lesions. The basis of this in vitro study was to analyze remineralization potential of two remineralizing agents like casein phosphopeptide stabilized amorphous calcium phosphate (CPP-ACP) and amorphous calcium fluoride phosphate (CPP-ACFP) on enamel after bleaching with 10% carbamide peroxide along with the mineral loss and uptake with the help of a X-ray diffractometer (XRD). |

Dental implants in children and adolescents |
p. 50 |
Santhosh Kumari, Mamta Harilal Nichani, C Vishnu Rekha, K Vijaya Prabha, VS Hariharan Children and adolescents often require prosthodontic rehabilitation for the restoration of edentulous areas which could be due to congenitally missing teeth and teeth lost due to trauma. These children are usually treated with removable prosthesis considering the fact that skeletal and dental growth and development is not completed and this treatment modality can lead to residual alveolar resorption, periodontal problems and increased risk of dental caries. The concern of placing implants in growing children is jaw growth. An osseointegrated implant behaves like ankylosed teeth and fails to move with surrounding structure leading to infraocclusion. When a choice is made to place the implant in growing children it should be closely monitored and implant prosthesis should be designed to accommodate the growth and development. This article is a review on placement of implants in children and effect of growth and development on implants. |
