Periodontal considerations determining the design and location of margins in restorative dentistry
Arvind Shenoy, Nina Shenoy, Roopa Babannavar
January-April 2012, 2(1):3-10
The first and most basic objective of restorative dentistry is preservation of the tooth structure. However, for the long-term survival of restoration the periodontium must also remain healthy or vice versa. The connective tissue of the attachment apparatus consists of three-dimensionally oriented fibers connecting firmly the tooth structures to the surrounding gingiva. Both the epithelial as well as connective tissue attachment contribute to a 'protection mechanism' in a most challenging area where the natural tooth penetrates the ectodermal integrity of the body. The attainment of this objective would be far less complex if it could be considered independent of restoration of function, comfort and esthetics, but such is not the case. The latter objectives usually require sophisticated restorative dentistry as often such esthetic restorations require placement of intra-crevicular margins without compromising on the periodontal health.

Acetal resin as an esthetic clasp material
K Lekha, NP Savitha, Meshramkar Roseline, Ramesh K Nadiger
January-April 2012, 2(1):11-14
Removable partial dentures (RPDs) are an effective and affordable treatment option for partial edentulism. Restoration of esthetics is an important function of RPD and it determines the success of the treatment. The goal of achieving optimal esthetics - while maintaining retentive integrity, stability, and protecting the health of the tooth - is the most difficult task. The traditional use of the metal clasp like cobalt chromium (Co-Cr), gold, stainless steel, and titanium hampers esthetics, since its obvious display conflicts with patient's prosthetic confidentiality. Acetal resin (polyoxymethylene or POM), a thermoplastic resin, may be used as an alternative denture clasp material. This material was promoted primarily on the basis of superior esthetics, which allowed the clasps to better match the color of abutment tooth. PubMed and Google Scholar were used to search original research articles, case reports, and other reviews about acetal resin. The keywords used were acetal resin, esthetic, clasp, removable partial denture, thermoplastic, metal free framework. This article is the result of a literature study on acetal resin clasp material for conventional RPD.

Continuing antiplatelet therapy throughout dental procedures: A clinical dilemma
Sheeraz Badal, Syed Ahmed, Rohit Shrikanthan, Afreen Badal
January-April 2012, 2(1):15-19
Antiplatelet therapy is commonly recommended for the prevention of the thromboembolic events, including the myocardial infarction and stroke. It has reduced the mortality and morbidity of cardiovascular diseases remarkably. A considerable number of patients presenting before a dentist give a history of antiplatelet therapy. A clinical dilemma exists whether to discontinue the antiplatelet therapy or to continue during the routine and invasive dental procedures. Continuing antiplatelet therapy during surgery minimizes the risk of thromboembolic complications but theoretically increases the risk of hemorrhage. Discontinuing antiplatelet therapy may expose patients to life-threatening thromboembolic events, while presumably reducing the risk of hemorrhagic complications. Diverse opinions exist regarding the management of such patients. Some advice continuation of the antiplatelet therapy rather than inviting possible thromboembolic event, while others encourages its discontinuation.

Perio-gnathic correction of traumatic anterior deep bite with skeletal class II and retrogenia
KV Arun Kumar, D Deepa
January-April 2012, 2(1):47-50
Correction of class II deep bite can be achieved by orthodontic treatment alone or by combination of orthodontics and orthognathic surgery. Orthognathic surgery is indicated when dental discrepancy cannot be corrected by the use of orthodontic mechanotherapy alone or when facial aesthetics are compromised. The purpose of this paper is to describe a technique of subapical osteotomy performed along with periodontal therapy, to correct the anterior traumatic deep bite, thus salvaging the mutilated teeth and achieving facial aesthetics.

Comparative evaluation of fluid absorbancy of retraction cords of different thickness after various medicament immersions
Shushant K Garg, Sandeep Garg, Sanjeev Mittal, Sangeeta Goyal
January-April 2012, 2(1):30-34
Purpose: To evaluate fluid absorbancy of retraction cords of different thickness after various medicament immersions. Materials and Methods: Ultrapak retraction cords of three different thicknesses (No. 000, 00, 0) with identical lengths (25 mm) were used. They were immersed in two different medicaments (25% aluminum chloride and saturated alum) for 20 min. Two different immersion fluids (artificial saliva and human plasma) were compared for fluid absorbancy. The capability of the cords to absorb fluids was measured by a gravimetric method. The data were analyzed by F test analysis and P<.05 was regarded as significant. Results: Regardless of the medicament used and immersion fluid, a relationship existed between cord thickness and the amount of fluid absorbed. There was a significant difference in the fluid absorbancy of all the three groups (P<0.01). A significant difference was also observed in the fluid absorbancy of saliva and plasma (P<0.05). Conclusion: The results of this study indicated that fluid absorbancy increased in linear proportion to the increase in thickness of the retraction cord. Ultrapak (#0) when treated with alum showed most favorable results. All the cords absorbed artificial saliva more than plasma irrespective of cord thickness and medicament used.

Glass fiber reinforced composite fixed partial denture as provisional tooth replacement in pre-adolescent age: A clinical report
Kaushal Kishor Agrawal, Pooran Chand, Neeraj Mishra, Kamleshwar Singh
January-April 2012, 2(1):51-53
The loss of anterior teeth is often a serious esthetic concern. Conventional fixed partial denture and implant-supported restorations may be the treatment of choice although non-impregnated fibers and fiber reinforced composite resins offer a conservative alternative for improved esthetics. This article describes a clinical situation in which non-impregnated fiber glass ribbon and fiber reinforced composite are successfully used to provisionally restore anterior edentulous area in an esthetic, functional and timely manner.

Daniely A Meireles, André A. F. Marques, Lucas F. R. Garcia, Angela D. B. Garrido, Emilio C Sponchiado
January-April 2012, 2(1):20-24
Aim: To assess the occurrence of apical transportation of mesio-vestibular canals of mandibular molars using two rotary techniques and one hybrid technique during shaping and cleaning. Materials and Methods: Forty-five human mandibular molars with a degree of mesial canal/root curvature of 20° to 55° were selected, which were included in acrylic resin blocks and randomly separated into three groups. Group 1-Fifteen teeth were debrided using the ProTaper rotary technique; Group 2-Fifteen teeth were debrided using the Manual Hybrid and ProTaper rotary technique; Group 3-Fifteen teeth were debrided using the PathFile-ProTaper technique. Apical deviation was assessed by the radiographic platform method that enables obtaining superimposed images of the first and last instrument used in root canal preparation in the same radiograph. Apical transportation was measured in millimeters with the aid of the Adobe Photoshop CS4 software. Results: The mean deviation for Group 1 was 0.03 mm, for Group 2, 0.1 mm and for Group 3, 0.08 mm. Statistical analysis (Kruskal-Wallis test) of the results demonstrated that there was no statistically significant difference among the samples (P>0.05) with regard to the apical deviation. Conclusion: The techniques provided minimum apical deviation.

Immunolocalization of c-Fos, c-Jun and Fra-2 in healthy human marginal gingival tissues
Nurullah Keklikoglu, Sevtap Akinci
January-April 2012, 2(1):25-29
Background and Objective: Keeping marginal gingiva healthy is possible with some cellular processes. Activator Protein-1 (AP-1) members Fos and Jun proteins regulate cellular processes including growth, proliferation, differentiation and apoptosis. The aim of this study was to compare of immunoreactivity (IR) of some same or different family member AP-1 proteins in cells forming marginal gingival mucosa. Materials and Methods: IR of Fos family members c-Fos (c-Fos-IR) and Fra-2 (Fra-2-IR) and Jun family member c-Jun (c-Jun-IR) were analysed in epithelial cells (ECs) and lamina propria cells (LPCs) of healthy human marginal gingiva by immunohistochemical method. Results: Both in ECs and LPCs, c-Fos-IR positivity was found higher than the others and Fra-2-IR positivity was found lower. The most postivity was observed in c-Fos-IR in ECs and the least IR was observed in Fra-2-IR in LPCs. Furthermore, the IR positivity percentage of all proteins was found higher in ECs than in LPCs. In the comparision of each of c-Fos-IR, c-Jun-IR and Fra-2-IR in ECs and LPCs, no statistically significant difference in c-Jun-IR was observed; however, there were statistically significant differences in c-Fos-IR and Fra-2-IR. Conclusions: According to these findings, it can be proposed that c-Fos protein in healthy gingiva is more related with physiological processes than other proteins. In this study, establishing a statistically significant difference between c-Fos-IR and Fra-2-IR in both ECs and LPCs has shown that as well as these proteins are within the same family, each one may be related with different cellular processes.
