For this essential step of root canal therapy, a number of devices and procedures have been developed and described. Nickel-titanium (NiTi) rotary devices have been a standard in clinical endodontics since their debut in 1988 because of their excellent ability to form root canals with possibly fewer procedural problems. Basic metallurgy of the alloy, including fracture processes and their relevance to canal anatomy, is required for safe clinical use of NiTi devices. This study examines the biological principles of root canal preparation, with a focus on the proper use of contemporary rotary NiTi instrumentation techniques and systems. The role and properties of contemporary root canal irrigants is also discussed.

Follow-up was done at 1, 3, 6, and 12 months and every 6 months thereafter. Clinical and radiographic examinations were performed at each recall. Results: Teeth involved was maxillary incisor in 12, maxillary cuspids in 20, mandibular incisors in 10 and mandibular cuspids in 14 cases. Prostheses were present in 25 and absent in 31 cases. Bony destruction pattern was apical in 45 and apico-marginal in 13 cases. Post was present in 14 and absent in 42 cases. The maximum healing was seen in maxillary incisor in 67% followed by maxillary cuspids in 52%, mandibular incisors in 65% and mandibular cuspids in 54%, 56% in teeth with prostheses, 82% in apical bone destruction and 76% in teeth with post. The difference was significant (P< 0.05). Conclusion: There was better healing in maxillary incisors, teeth with prostheses present, teeth with apical bone destruction and teeth with post.

It poses esthetic problem which could be a prime concern for many patients, especially in anterior region of teeth that may be compromised due to previous trauma, caries, or failed restorations. Bleaching is a more conservative approach which is noninvasive as compared with other prosthodontic options like crowns or veneers. Among various bleaching techniques, “Walking bleach technique” is preferred, as it provides better cosmetic outcome with limited side effects. This article aims at presenting a case on walking bleach method performed on endodontically treated teeth, after which a satisfactory aesthetic result was achieved.

Dental fluorosis, tetracycline staining, localised and chronological hypoplasia, and both amelogenesis and dentinogenesis imperfecta can all produce a cosmetically unsatisfactory dentition. The aetiology of intrinsic discolouration of enamel may sometimes be deduced from the patient's history, and one factor long associated with the problem has been a high level of fluoride intake. Optimal use of topical fluorides leads to a decrease in the caries prevalence but may show an increase in the prevalence of fluorosis staining because of metabolic alterations in the ameloblasts, causing a defective matrix formation and improper calcification. A 28 yr female patient was screened at the Department of Conservative Dentistry and Endodontics at desh bhagat dental college, mandi gobindgarh, Punjab....

Tooth wear is the result of four processes: abrasion (wear produced by interaction between teeth ... more Tooth wear is the result of four processes: abrasion (wear produced by interaction between teeth and other materials), attrition (wear through tooth-tooth contact), abfraction and erosion (dissolution of hard tissue by acidic substances). A further process (abfraction) might potentiate wear by abrasion and/or erosion. Knowledge of these tooth wear processes, and their interactions is reviewed. Both clinical and experimental observations show that individual wear mechanisms rarely act alone but interact with each other. The most important interaction is the potentiation of abrasion by erosive damage to the dental hard tissues. Saliva can modulate erosive/abrasive tooth wear, especially through formation of pellicle, but cannot prevent it.

It is not a disease and no individual is ever at zero risk of sustaining these potentially life-changing injuries. The aim of this article was to review the literature on the prevalence, incidence, a etiology, prognosis and outcomes of dental trauma. The importance of standardized reporting, oral health policy, adjunctive research methods, prevention and education will also be discussed. Approximately one-third of children and toddlers (primary teeth) and one-fifth of adolescents and adults (permanent teeth) sustained a traumatic dental injury. The majority involved the maxillary central incisors, mainly from falls in toddlers at home and contact sport in adolescents.

Differentiating between periodontal and endodontic problems can be difficult. A symptomatic tooth may have pain of periodontal and/or pulpal origin. The nature of that pain is often the first clue in determining the etiology of such a problem. Radiographic and clinical evaluation can help clarify the nature of the problem. In some cases, the influence of pulpal pathology may create periodontal involvement. In others, periodontal pathology may create pulpal pathology. This review article discusses the various clinical aspects to be considered for accurately diagnosing and treating endo-perio lesions.

Materials and Methods: Sixty extracted, human, single-rooted mandibular premolars were selected. Endodontic treatment was performed using ProTaper Universal NiTi rotary instruments. Half of the samples were obturated with Tubliseal and remaining half were obtutared with AH Plus sealer with cold lateral compaction method. Subsequently, twenty teeth were retreated with manual retreatment system, and each twenty teeth was retreated with two different rotary retreatment systems. The roots were then grooved longitudinally, and both root halves were subjected to assessment under stereomicroscope, and images were taken with a digital camera. These images were evaluated for residual obturating material using AutoCAD software. Analysis of variance test and Bonferroni multiple comparison test were used for statistical analysis. Results and Conclusion: Results of the present study showed that no system was able to completely remove all debris from the root canals. The minimum amount of debris was seen in the group obturated using Tubliseal sealer and retreated with Hyflex NT retreatment system followed by Mtwo retreatment system and finally the manual retreatment protocol. Regarding the time taken, Mtwo retreatment files took least time to remove the obturating material in all sealer groups.

The root-end filling material used should not allow the contamination of the periapical tissue. The aim of the present study was to compare the ability of white mineral trioxide aggregate (MTA), white Portland cement (PC) and intermediate restorative material (IRM) for sealing root-end by dye leakage test. Materials and Methods 120 teeth with single root were prepared through instruments. Following obturation, the apex was cut, and a cavity was made. Then, the teeth were divided into four groups (Group I: MTA, Group II: white PC, Group III: IRM, Group IV: control). Cavities made at apex in the first three groups were then filled with the respective materials. Exposure to the dye, India Ink, was then done for a time period of 72 hours. The depth of penetration of dye inside the whole root was then evaluated with a magnification of 16X under stereomicroscope in vit...
