ARTICLES
Retention of endodontic post - A review
A Fernandes, S Rodrigues, G SarDessai, A Mehta
January-March 2001, 13(1):11-18
DOI:10.4103/0970-7212.351795  
The restoration of endodontically treated teeth with post and core is a challenge. Success will depend on proper diagnosis, selection of teeth to be restored, the type of post and the knowledge and skill of the dentist. Adequate retention of the post is a pre requisite for the clinical success of the post retained crown. The retention of post depends on the length, diameter, design adaptation, method of cementation, lubrication of canal, post material, and position in the arch. While considering any post, the dentist must weigh retention against stress distribution, so as to attain optimum balance between retention and resistance to root fracture.

C-shaped mandibular molar - Obturation by chemoplasticized gutta-percha technique
K Kumar, KS Bhat
January-March 2001, 13(1):27-30
DOI:10.4103/0970-7212.351799  
Variations in the root canals configuration is not uncommon. One of the common variation frequently encountered in mandibular molar is the C- shaped canal. The c-shaped canal configuration is difficult to identify radiographically and exhibit considerable difficulty in cleaning, shaping and obturation of the root canal system. Hence plasticized gutta-percha obturation methods have been recommended to obturate such canals, with most of them orienting towards the expensive thermoplasticized gutta-percha obturation technique.This case report shows that chemoplasticizing gutta- percha using rectified white turpentine as a solvent can be a suitable alternative to other methods of obturation of such complex root canals.

Anti-microbial effect of various calcium hydroxide preparations - An in-vitro study
J George, K Kartik, L Lakshminarayanan
January-March 2001, 13(1):2-7
DOI:10.4103/0970-7212.351797  
A study was conducted to evaluate the antibacterial activity of various calcium hydroxide Ca(OH)2 preparations Their activity was tested against 4 facultative anaerobes. Four types of preparations were used (1) Ca(OH)2 in glycerine (2) Ca(OH)2 with equal amounts of base and catalyst mixture (3) Ca(OH)2 with more catalyst and less base and (4) Ca(OH)2 powder mixed with saline.The anti-bacterial activity was checked at 60 min, 24 hrs, 4 days and 5 days. The viability of the bacterial cells were checked by subculture into a fresh media at durations fixed as above. The anti-bacterial effect of Ca(OH)2 with saline ranged from 50% to 100% against the organisms tested. The second preparation had no effect on Staphylococcus-aureus and Micrococcus till the end of 5 days, Streptococcus faecalis was destroyed in 24 hrs and its effect against Streptococcus viridans was 50% at the end of 5 days. The third preparation had no effect on any microorganism in 60 min but 90% of the bacteria were destroyed in 24 hrs and at the end of the 5th day it had destroyed all the organisms. Ca(OH)2 with glycerine did not show any anti-bacterial effect on any organism even at the end of the 5th day.

Emergence of a new threat: Latex allergy - A case report
AP Tikku, J Soma
January-March 2001, 13(1):24-26
DOI:10.4103/0970-7212.351798  
Allergy is by far one of the most common diseases affecting about 10% of the population. Allergy to latex appears to be a relatively new and increasingly frequent problem. The reason for this is not clear, but includes increased use of latex gloves over the past decade and changes in the manufacture of latex products. In this particular case an eighteen year old lady who was given restorative treatment for multiple carious teeth, reported with complication of contact dermatitis- days after the treatment. On through investigations for all the allergens the allergy was found to be from latex gloves.

Endodontic miscellany: Endo-ortho management of subgingival transversely fractured tooth
S Kathuria, P Kathuria, RK Sharma, S Goyal
January-March 2001, 13(1):31-34
DOI:10.4103/0970-7212.351800  
Endodontic-orthodontic treatment may become necessary to save teeth with advanced caries, traumatic destruction of clinical crown, lateral root perforation, external or internal rsorption near the alveolar crest or overzealous tooth preparation. With such treatment these teeth may not offer sound tooth structure on which to place a restoration. Lengthening the clinical crown by removing supporting bone to expose sound tooth structure or eliminate the existing periodontal defect is the solution usually recommended. Forced orthodontic eruption in conjunction with endodontic, periodontal & restorative therapy is an alternative.

Taurodontism - Review and an endodontic case report
R Sathyanarayanan, U Carounanidy
January-March 2001, 13(1):8-10
DOI:10.4103/0970-7212.351802  
A case report of taurodontism in teeth # 36 and 37 is reported in this article. A conventional root canal treatment was carried out for these pulpally9 involved teeth. A six month recall showed a favourable prognosis both clinically and radiographically.

The endodontic dilemma - Rationale behind antibiotic usage
G Krishnan, A Parameswaran
January-March 2001, 13(1):19-23
DOI:10.4103/0970-7212.351796  
Antibiotics are life saving therapeutic agents of inestimable value. Many dental surgeons prescribe antibiotics to prevent the possible development of pain and swelling during endodontic therapy. This is being done more out of tradition rather than with any sound scientific knowledge. This sorry state of affairs has contributed to an alarming increase in the rate of microbial resistance to antibiotics. The objective of this paper is to enlighten the dental fraternity about the true rationale behind advocating antibiotics during endodontic therapy. It is imperative that dental surgeons appreciate the fact that antibiotics are useful adjuncts during endodontic therapy, and are not indispensable. In this article, we have delineated the true indications for antibiotic prophylaxis in Endodontics as well as given an overview of the conditions, which warrant such coverage.
