Permanent molar pulpotomy with a new endodontic cement: A case series
Saeed Asgary, Sara Ehsani
January-March 2009, 12(1):31-36
DOI:10.4103/0972-0707.53340  PMID:20379438
The aim of this case series was to determine the clinical and radiographic success rate of pulpotomy, with new endodontic cement (NEC), in human mature permanent molar teeth. Twelve molars with established irreversible pulpitis were selected from patients 14 - 62 years old. The selection criteria included carious pulp exposure with a positive history of lingering pain. After isolation, caries removal, and pulp exposure, pulpotomy with NEC was performed and a permanent restoration was immediately placed. At the first recall (+1 day) no patients reported postoperative pain. One wisdom tooth had been extracted after two months because of failure in coronal restoration. Eleven patients were available for the second recall, with a mean time of 15.8 months. Clinical and radiographic examination revealed that all teeth were functional and free of signs and symptoms. Histological examination of the extracted teeth revealed complete dentin bridge formation and a normal pulp. Although the results favored the use of NEC, more studies with larger samples and a longer recall period were suggested, to justify the use of this novel material for treatment of irreversible pulpitis in human permanent molar teeth.

International Caries Detection and Assessment System: A new paradigm in detection of dental caries
KM Shivakumar, Sumanth Prasad, GN Chandu

A new emphasis on caries measurement and management is required for the dental community. The dental professionals need new approaches in caries detection, its assessment, and management. The future of research, practice, and education in Cariology requires the development of an integrated definition of dental caries, and uniform systems for measuring the caries process. Keeping this in view, the International Caries Detection and Assessment System (ICDAS) has presented a new paradigm for the measurement of dental caries, which was developed from the systematic reviews of literature on the clinical caries detection system and other sources. The ICDAS can serve as a basis and benchmark for clinical and epidemiological research and inform dental undergraduate and postgraduate teaching in Cariology. The ICDAS system was developed to bring forward the current understanding of the process of initiation and progression of dental caries to the fields of epidemiological and clinical research.

Canal-centering ability: An endodontic challenge
Deivanayagam Kandaswamy, Nagendrababu Venkateshbabu, Ilango Porkodi, Gali Pradeep
January-March 2009, 12(1):3-9
DOI:10.4103/0972-0707.53334  PMID:20379433
During instrumentation of the root canal, it is important to develop a continuously tapered form and to maintain the original shape and position of the apical foramen. However, the presence of curvatures may cause difficulty in root canal instrumentation. The ability to keep the instruments centered is essential to provide a correct enlargement, without excessive weakening of the root structure. Several studies have shown that Ni-Ti instruments remain significantly more centered and demonstrated less canal transportation than stainless steel files. Considerable research has been undertaken to understand the several factors related to an instrument's canal-centering ability. In this article, we have discussed the influence of various parameters such as alloys used in the manufacture of instruments, instrument cross-section, taper, and have given tips on canal-centering ability.

Can coffee prevent caries?
PC Anila Namboodiripad, Sumathi Kori
January-March 2009, 12(1):17-21
DOI:10.4103/0972-0707.53336  PMID:20379435
Aim: To determine the anti-carious effect of coffee in humans. Coffee represents one of the most consumed products by the population. Materials and Methods: A random sample of 1000 individuals, of both sexes, who consumed only coffee as a beverage and who visited the Out-Patient Department of KLE Society's Institute of Dental Sci­ences, with a dental complaint and no history of any major illness, were considered as subjects. The patients' histories with regard to the coffee intake, such as, period of consumption, frequency of consumption, whether taken with milk or wihout milk, with sugar or without sugar, and the brand make, was noted. History of the type of diet, consumption of sweets, periodic­ity of brushing, and whether they had undergone fluoride applications were also noted. A thousand patients who consumed beverages other than coffee were taken as the control. Results: The results showed that coffee most consumed was roasted coffee, and the frequency on an average was about three cups per day, for an average period of 35 years. The Decayed/Missing/Filled Surface (DMFS) scores varied from 2.9, in subjects who drank black coffee, to 5.5 in subjects who consumed coffee together with sweeteners and creaming agents. The DMFS score was 3.4 in subjects who consumed coffee together with milk but no sugar. The DMFS score of the control subjects was 4, indicating that coffee if consumed alone had anticaries action, but in the presence of additives the antibacterial and anticaries action was totally minimized. Conclusion: Thus coffee can help in prevention of dental caries if consumed without additives.

Canal complexity of a mandibular first molar
S Poorni, R Anil Kumar, R Indira
January-March 2009, 12(1):37-40
DOI:10.4103/0972-0707.53341  PMID:20379439
The endodontic treatment of a mandibular molar with aberrant canal configuration can be diagnostically and technically challenging. This case report presents the treatment of a mandibular first molar with five root canals, of which three were located in the mesial root. A third canal was found between the mesiobuccal and mesiolingual root canals. The morphological pattern of separate apical terminations of three mesial root canals with separate orifices, as manifested in this case, is a rare one.

A comparison of surface roughness after micro abrasion of enamel with and without using CPP-ACP: An in vitro study
Jones Mathias, S Kavitha, S Mahalaxmi
January-March 2009, 12(1):22-25
DOI:10.4103/0972-0707.53337  PMID:20379436
Aim: The aim of this study was to evaluate the surface roughness of enamel after micro abrasion with and without using remineralization agent, CPP-ACP (Casein Phosphopeptide-Amorphous Calcium Phosphate). Materials and Methods: Thirty freshly extracted anterior teeth were collected. The samples were randomly assigned to two study and one control group. Group A (n = 10) containing teeth in which only micro abrasion was done, Group B (n = 10) containing teeth in which CPP-ACP (G C Tooth Mousse) was applied after micro abrasion for a period of 30 days, once daily for three minutes and Group C (n = 10) in which no preparation was done and which acted as the control group. The samples were stored in artificial saliva and evaluated after 30 days, using surface profilometer. The results were tabulated and statistically analyzed. Results: According to the results of this study, a combination of the micro abrasion procedure and CPP-ACP application reduced the enamel surface roughness significantly, when compared to micro abrasion done alone. Conclusion: Application of CPP-ACP after micro abrasion procedure significantly reduces the enamel surface roughness thereby decreasing the risk of caries.

Kanika Attam, Sangeeta Talwar, Seema Yadav, Sanjay Miglani
January-March 2009, 12(1):26-30
DOI:10.4103/0972-0707.53338  PMID:20379437
Aim: This study compares the effect of formalin and autoclaving the tooth samples by evaluating microleakage in-vitro . Materials and Methods: Forty-five extracted human permanent incisor teeth were taken and randomly divided into three groups (with different methods of storage and disinfection) with 15 teeth each: Group 1: Control-extracted teeth in this group were stored in normal saline, Group 2: the extracted teeth in this group were stored in 10 % formalin for two weeks and Group 3: the extracted teeth were Autoclaved at 121°C, at 15 psi pressure for 40 minutes. In all the groups after the specified storage period, class V cavities were prepared on the labial surface and restoration was performed with Z100 restorative. Finished and polished samples were subjected to 500 cycles of thermocycling. All specimens were immersed in methylene blue for 24 hours. After sectioning, the margins of restora­tion were evaluated for dye leakage at 10 X magnification, using an optical microscope. Data were subjected to nonparametric Kruskal Wallis one way analysis of variance. Inter-group comparisons were performed using the Mann Whitney test ( P < 0.05). Results: The authors found that the microleakage in the formalin group was considerably lower than that in the control group. The autoclave group showed slightly higher mean microleakage, but the difference was not statistically significant. Conclusion: Both autoclaving and formalin storage affect, to a varying degree, the microleakage values in vitro . The results in the autoclaving group matched those of the control group more closely, with only a slight difference.
