ABSTRACT

Cracks and fractures in teeth are difficult to diagnose and treat, especially in the initial stages. The etiology of cracks is still obscure. With an increase in both geriatric population and tooth retention, the incidence of cracked teeth can also increase. There are many types of cracks from simple craze lines to vertical root fracture. An astute clinician should make crack detection a part of diagnostic screening. Proper diagnosis and treatment of cracked teeth is not possible without knowledge of the types of cracks along with associated signs and symptoms. This review presents a brief introduction to the various types of cracks and will aid the clinician in crack identification and management.

Keywords: Cracked tooth, Fractured cusp, Vertical root fracture.

ABSTRACT

Aim: To evaluate the maximum depth of sealer penetration into dentinal tubules at the coronal, middle, and apical third of root canals, following the use of different final irrigation solutions.

Materials and methods: Eighty freshly extracted mandibular premolars were selected for the study. After decoronation, instrumentation of samples was done using Protaper universal rotary file system till F4. During shaping and cleaning of root canal, 5.25% concentration of sodium hypochlorite (NaOCl) was used for irrigation. The samples were then randomly divided into four groups (n = 20) depending on the final irrigating solution used. Group I: 17% aqueous ethylenediaminetetraacetic acid (MA) (aq. EDTA); group II: 10% citric acid (CA); group III: 5% maleic acid; group IV: 5.25% conc. NaOCl. Passive ultrasonic irrigation (PUI) was used to activate each final irrigating solution. The samples were obturated using warm lateral condensation technique with guttapercha coated with AH plus sealer mixed with rhodamine B dye. Confocal laser scanning microscopy (CLSM) examined the sealer penetration depth.

Results: The Kruskal-Wallis analysis results showed that there was a significant difference in the maximum depth of sealer penetration among all groups in all sections (p < 0.05). The coronal sections of the root canals in each group showed a significantly higher depth of sealer penetration than did the apical and middle sections (p < 0.05).

Conclusion: A combination of 17% aq. EDTA and PUI used for final irrigation proved to be more effective for sealer penetration into the dentinal tubules.

Clinical significance: Final irrigation protocol followed is of paramount importance in achieving complete disinfection within the root canal, and also the penetration of sealer serves as an indicator of the extent to which the smear layer was removed.

Keywords: Citric acid, Dentinal tubules, Ethylenediaminetetraacetic acid, Final irrigation, Sealer penetration.

ABSTRACT

Endocrowns are a viable option for the restoration of extensively damaged endodontically treated posterior teeth. The main objective is to achieve a bonded biomimetic reconstruction, i.e., minimally invasive of root canals. The clinical procedure that involves the endocrown fabrication may be considered less complex, more practical, and easier to perform when compared with that of conventional crowns with post and core. This article highlights two different case reports of badly mutilated endodontically treated teeth, effectively managed by means of endocrown-type restorations fabricated with both metal-free and metal ceramicbased prostheses with a 6-month follow-up period.

Keywords: Badly mutilated teeth, Biomimetic reconstruction, Endocrown, Esthetics, Pulpless teeth.

ABSTRACT

Aim: This study is aimed to evaluate the effect of staining solutions on the color stability of bulk fill and conventional nanohybrid resin composites (RCs) when subjected to various immersion periods.

Materials and methods: A total of 120 cylindrical Teflon molds (4 × 4 mm) were obtained and divided into four groups of 30 each. Molds of groups I and II were filled with Tetric N Ceram Bulk Fill (Ivoclar Vivadent, Schaan, Liechtenstein) and Filtek Bulk Fill (3M ESPE, St. Paul, MN, USA). Molds of groups III and IV were filled with Tetric N Ceram (Ivoclar Vivadent) and Filtek Z250 XTE (3M ESPE) incremental fill RC. Photo-activation was performed and specimens were incubated. Spectrophotometer analysis was done according to Commission Internationale d’Eclairage Lab color scale. After taking the baseline measurements, 10 samples from each group were immersed in distilled water (control, subgroup a), tea (subgroup b), and coffee (subgroup c) respectively, for 1, 7, and 30 days. The color values of each specimen were remeasured and color change value (E*ab) was calculated after 1, 7, and 30 days. Data were analyzed by Friedman’s test and Mann–Whitney U-test; p < 0.05 is considered to be statistically significant.

Results: Group III specimens showed perceptible color changes at 30-day immersion period in coffee and tea. In group I specimens, color changes were perceptible at 7- and 30-day immersion periods in coffee and only 30-day immersion period in tea. Groups II and IV specimens showed perceptible color changes after all immersion periods in coffee and after 30 days in tea.

Conclusion: It can be concluded that Tetric N Ceram has less color change than the other nanohybrid RCs investigated when immersed in coffee and tea after various immersion periods.

Keywords: Bulk fill composite, Coffee, Color stability, Incremental fill composite, Tea.

ABSTRACT

Dentistry is an extremely important and foremost healing profession. In today’s world, with the increasing ecological disasters, it is highly obligatory to understand the paramount importance of being eco-friendly in every facet of our lives, including in dental practice, which has a huge impact on the environment. Eco-friendly dentistry is a term legally accepted by the Eco Dentistry Association, which is an emerging concept in dentistry. It is an approach to minimize the environmental hazards of dental practice and provide dental care in an environmentally friendly way. With the widespread introduction of beryllium into the dental industry, a large number of these workers are at risk for the development of chronic beryllium disease. Proper handling of biomedical and dental waste is indispensable for the dental profession. People have become much more cognizant of potentially harmful chemicals contained in plastic products, especially, bisphenol-A. This can be achieved by reducing waste and lowering pollution. Dental offices can use reusable towels, high-efficiency machines, and paperless records. A small change can make the overall impact of the dental office less damaging to the environment.
The purpose of this review is to discuss various ways that a dentist can choose to make the dental office “Green” and conserve precious resources with all the options available today. Eco-friendly dentistry is soon becoming the standard.

Keywords: Biomedical, Ecodentistry, Green.

ABSTRACT

In the recent years, there is a paradigm shift in the management of necrotic immature permanent teeth, with most of these teeth being treated by revascularization rather than conventional apexification procedure. Current regenerative endodontic protocols (REP) emphasizes the need to have a disinfection protocols that will enable good disinfection without causing damage to stem cells. The current available evidence suggest that true pulp-dentin complex is not being formed after REP, nevertheless it can result in continued root development that will enable such tooth to survive for a long time. This article highlights the recent trends in revascularization procedures.

ABSTRACT

Management of dental pain during and after endodontic treatment remains a big challenge. Dental anxiety can also influence the patient’s perception of pain and is known to directly lower the pain threshold. Psychological intervention in acute dental pain may be a very effective noninvasive measure to reduce pain. However, the pulp that has been diagnosed with irreversible pulpitis, with spontaneous, moderate-to-severe pain may not respond to the local anesthetic (LA) enough for the operator to pursue a painless treatment. In this review, pain predisposing factors and pain prevention techniques are evaluated, and various strategies to overcome anesthetic failures are reviewed which will help the practitioner achieve effective pain management.

Keywords: Anesthesia, Irreversible pulpits, Pain, Root canal, Success.

ABSTRACT

The Father of Modern Dentistry, Greene Vardiman Black, had played a vital role in elevating the dental profession to an autonomous status. Modern dentistry has continuously evolved from the time of GV Black. Now, there has been a paradigm shift in concept from ‘Extension for prevention’ to ‘Restriction with conviction’. ‘Medical model’ of caries management has been recognized as the most logical approach for success. The prediction of GV Black that ‘The professional person has no right to be other than a continuous student’ has become a reality. It is the duty of every conservative dentist to appreciate and adopt the changes and this will be the real tribute paid to the pioneers of the profession.

Keywords: Evolving principles, GV black, Modern dentistry.

ABSTRACT

The success of endodontic treatment has been of great interest to practitioners for many years now. Endodontic failures, which are of particular interest to us, are due to either microbial or nonmicrobial reasons. It is often thought that procedural errors like ledging, perforation, overfilling, underfilling or instrument separation invariably result in failure. In reality, the fact is that such mishaps only impede the accomplishment of an ideal root canal treatment. It is often the concomitant presence of infection that ultimately results in failure.
Numerous studies have evaluated the success or failure of endodontic therapy and reported a wide range of success rates from 40 to 93%.This wide range may be due to differences in clinical procedure, experimental design, criteria for evaluation and the length of the observation period. However, most authors conclude that the crucial factor influencing success is the preoperative status of the tooth. Teeth with an apical radiolucency show a 20% lower success rate than teeth without lesion.
Till date, the main method of evaluating success is radiographic, using recall radiographs. This method, however, is not without its own limitations due to examiner bias and inconsistencies.
The factors affecting treatment outcome include those related to diagnosis, preoperative condition of the patient and tooth, standard of care during treatment, postoperative factors and ongoing maintenance. This paper reviews the various factors influencing the outcome of endodontic treatment in light of modern thought.

Keywords: Failure, Postoperative factors, Preoperative factors, Standard of care, Success, Treatment outcome.

ABSTRACT

External root resorption of teeth takes its origin from periodontal tissues but is often an endodontic enigma. A combined endoperio management is required if the external resorption involves both entities. This article describes the management of an external resorption in mandibular first molar by intentional reimplantation using cone-beam computed tomography (CBCT) as an adjunctive diagnostic aid. Following atraumatic extraction of 36, endodontic treatment was performed extraorally, followed by sealing of the resorptive site using Biodentine. The periodontal procedures included guided tissue regeneration using a bioresorbable membrane and placement of osseograft for bone regeneration. After a follow-up period of 10 months, the patient was totally asymptomatic. Intentional reimplantation is a viable treatment option for external root resorption of inaccessible sites.

Keywords: Biodentine, External cervical root resorption, Guided tissue regeneration, Intentional reimplantation.
