Enhancing Aesthetics and Functionality of the Teeth Using Injectable Composite Resin Technique.

In order to prepare composite restorations without the requirement for tooth preparation, the injectable composite resin technique uses a clear silicone index in a minimally invasive direct approach to imitate a diagnostic wax-up. This case report features a 34-year-old female patient having aesthetic and functional concerns, notably spacing between the teeth, insufficient tooth visibility, and diastema in the upper anterior region. Upon clinical examination, spacing and midline diastema were observed. The maxillary incisors and canines were to have composite veneers made as part of the treatment plan. A wax-up and transparent silicone index was prepared following the assessment of a try-in of the prepared mock-up. Subsequenty, for restoring the teeth, a clear silicone index was used to inject and polymerize the flowable composite. The desired outcomes included elongated teeth to enhance visibility, closure of diastemas, and reshaping of the canines. Over a 12-month follow-up period, the patient exhibited no signs of soft tissue inflammation or significant wear. The described technique is characterized by its minimal invasiveness, cost-effectiveness, and suitability for definitive and provisional restorations. Desirable results can be achieved by appropriate planning and adhering to a meticulous planning while minimizing tooth structure loss.

Comparative Evaluation of the Efficacy of TheraCal LC, Mineral Trioxide Aggregate, and Biodentine As Direct Pulp Capping Materials in Patients With Pulpal Exposure in Posterior Teeth: A Triple-Blinded Randomized Parallel Group Clinical Trial.

Background The aim was to evaluate and compare the efficacy of TheraCal LC, mineral trioxide aggregate (MTA), and Biodentine as direct pulp capping (DPC) materials in patients with pulpal exposure in the posterior teeth. Methodology A total of 54 samples were assessed for eligibility. Out of this, 12 teeth samples failed to meet the inclusion criteria. Finally, 42 teeth samples were selected which were randomly distributed into three groups (n = 14). Groups A, B, and C received the intervention of MTA, Biodentine, and TheraCal LC, respectively. The assessment was performed clinically to check for postoperative pain, tenderness, and neural sensibility, and the radiographs were used to check the presence of periodontal ligament (PDL) space widening, calcified barrier, and periapical radiolucency at the follow-up of 21 days, three months, and 12 months. The outcomes depended on the clinical and radiographic success rates recorded at 12 months of recall. Results Overall successful outcome of DPC clinically at different periods was 97.61% at three months and 88.09% at 12 months. A Chi-square test was used which showed that the difference was statistically nonsignificant. For groups A, B, and C, the success rate at follow-up came out to be 85.71%, 100%, and 78.57% at 12 months, respectively. The overall radiographic success rate of DPC at different time periods was 83.33% at three months and 88.09% at 12 months. A Chi-square test was used which showed that the difference was statistically nonsignificant. For groups A, B, and C, the success rate at follow-up came out to be 85.71%, 100%, and 78.57% at 12 months, respectively. Conclusion Resin-based calcium-silicate agent (TheraCal LC) showed good efficacy and can be used in practice with the predictability of a good success rate both clinically and radiographically. Thus, TheraCal LC can be utilized as an alternative to MTA or Biodentine in clinical practice, with the predictability of similar successful outcomes in patients with pulpal exposure in the posterior teeth.

Anterior Matrix Systems for Composite Restorations: A Review.

In the field of restorative dentistry, composite resins have emerged as the most utilized materials. They revolutionized the cosmetic approach to anterior tooth treatment since their introduction to dental practice. In cases where one or more of the tooth's walls are absent, matrices are employed to assist in the creation of the proper anatomic contour and proximal contacts without the occurrence of gingival overhangs. Matrices come in a variety of designs suitable for various therapeutic conditions. Depending on the level of tooth destruction, they might range from a simple metal or plastic strip to a circumferential ring of metal surrounding the entire crown. Although the handling characteristics of modern composites have significantly improved, dentists still encounter challenges with the development of good interproximal contact and proper anatomical contour. The utilization of an anterior matrix system can be paramount in achieving these objectives.

The Comparative Evaluation of Postoperative Pain After the Use of WaveOne Gold and TruNatomy Filing Systems in a Tooth With Irreversible Pulpitis: An Observational Study.

Introduction The present study aimed to clinically compare the incidence of postoperative pain after the endodontic treatment of posterior teeth using the WaveOne Gold (WOG) and TruNatomy (Dentsply Maillefer, Ballaigues, Switzerland) filing systems. The study gives a better understanding of the association of postoperative pain and filing systems used. The patients were selected in such a manner that they have a similar diagnosis before the initiation of treatment. It also helps to understand if the postoperative pain is dependent or independent of the filing system used. Methods In the study, 32 vital teeth with irreversible pulpitis with no periapical lesion were selected for the study. The patients were divided into two groups (n=16) according to the instrumentation system used (WaveOne Gold group and TruNatomy group). The treatments were performed in a single session. The participants were asked to rate the intensity of postoperative pain on a visual analog scale (VAS) (no pain, mild pain, moderate pain, and severe pain) after 24 hours, 72 hours, and seven days; the tests of significance used are Friedman test or Mann-Whitney test. Results The incidence of postoperative pain is comparatively less in WaveOne Gold group after 24 and 72 hours compared with those in the TruNatomy group. No postoperative pain is experienced after seven days by the participants of both groups. Conclusions Postoperative pain is expected more after the preparation of the root canal system with the TruNatomy as compared to WaveOne Gold.

A Breakthrough in the Era of Calcium Silicate-Based Cements: A Critical Review.

Calcium silicate-based cements (CSCs) or mineral trioxide aggregate (MTA) lookalike materials are blocks of cement or root canal sealers produced from calcium (Ca) and silicate. They have superior sealing ability, bioactivity, and marginal adaptability, making them appropriate for various dental treatment applications. Mineral trioxide aggregate is widely used in numerous endodontic repair techniques. The capacity of this cement to promote tissue regeneration and stimulate mineralization accounts for its widespread usage in pulp capping, apexification, apical surgeries, and revascularization. Several studies have been conducted to investigate changes in the components of MTA-based types of cement directed to improve their presentation clinically. To improve flowability, new Ca silicate-based formulations have been introduced commercially. In these new formulations, essential features such as adequate radiopacity and setting time, color stability, alkaline pH, and calcium ion release and biocompatibility must be considered. Owing to an increased range of indications of CSCs, including some for restorative dentistry, and with the emergence of novel silicate calcium-based materials with considerable changes in their compositions, it is necessary to examine the available scientific literature that evaluates their usage in these applications. Therefore, this review paper aims to assess the existing knowledge of CSCs, emphasizing their potential uses in restorative and endodontic dentistry. This report strives to update doctors' understanding of CSCs, allowing for a better therapeutic approach.

Bromelain: A Potent Phytomedicine.

The commercially available protein-digesting enzyme bromelain is derived from the pineapple fruit or stem. Bromelain from fruit and stems are produced in different ways and has varied enzyme compositions. "Bromelain" often refers to the "stem bromelain". Bromelain is a combination of several thiol endopeptidases and others including various protease inhibitors, glucosidase, cellulase, phosphatase, peroxidase, and escharase. Studies conducted in both the lab and on animals show that bromelain has a variety of fibrinolytic, anti-edematous, antithrombotic, and anti-inflammatory effects. The body can absorb bromelain to a significant extent without it ceasing its proteolytic activity or having any negative side effects. Numerous therapeutic advantages of bromelain include wound debridement, improved drug absorption, and the management of sinusitis, bronchitis, angina pectoris, surgical trauma, and thrombophlebitis. Additionally, it treats numerous cardiovascular conditions, diarrhoea, and osteoarthritis. Bromelain also encourages apoptotic cell death and exhibits some anti-cancerous properties. This review compiles the crucial traits, medical and dental uses of bromelain as well as its potential mechanism of action.

Conservative Management of Complicated Crown-Root Fracture: An Immediate Esthetic Rehabilitation.

Among the various types of dental trauma, crown-root fractures are one of the most challenging to treat and require a multidisciplinary approach. This paper reports a case of a complicated crown-root fracture of maxillary left central incisor with esthetic, functional complications. An 18-year-old male patient presented to the department immediately after suffering trauma with a complicated crown-root fracture on tooth 21. As per the treatment, the patient had undergone endodontic therapy followed by flap reflection. Post flap reflection, a glass fiber post was luted, and the fractured fragment was reattached. By this approach, in the same appointment, the cervical margin can be exposed with appropriate isolation followed by a reattachment procedure. Reattaching the fragment is a viable option as it can be done immediately, provides better esthetics, restores function, and is less complicated than the conventional approach. A good prognosis is dependent on patient cooperation with the understanding of the treatment limitations. The article discusses a successful case of complicated crown-root fracture treated with the reattachment of a tooth fragment. Eighteen months of clinical and radiographic evaluation revealed that the clinical protocol was effective, as the tooth was functional, asymptomatic, and esthetic.

Clinical Efficacy of Two Different Desensitizers in Reducing Postoperative Sensitivity Following Composite Restorations.

OBJECTIVE: The objective is to evaluate the efficacy of different desensitizing agents in the reduction of postoperative sensitivity after composite restoration. MATERIALS AND METHODS: Class I cavities were prepared in 39 patients by the same operator. The patients included in the study were between 20 and 45 years with vital pulp and a remaining dentin thickness of 1mm. Previously restored, nonvital and tooth with periodical changes were excluded. Patients were randomly assigned into three groups of 13 each - Group I (Control); Group II (Gluma desensitizer) and Group III (shield active desensitizer [SAD]). After the surface treatment, the teeth were restored with composite. The patients were assessed for postoperative sensitivity at 24 hours and one week with a visual analog scale (VAS). STATISTICAL ANALYSIS: Data were analyzed using SPSS v23 software. Data were analyzed using one-way ANOVA and post-hoc Tukey test. RESULTS:  Gluma and SAD on comparison with control group i.e. composite group showed statistical significance difference at day 1 (P-value 0.003), but on comparing the sensitivity after one week, there is no significant difference in sensitivity score between all three groups (P-value 0.073). There was no statistically significant difference between day 1 and one week when comparing Gluma desensitizer and SAD. CONCLUSION: The application of the desensitizer led to a statistically significant reduction in postoperative sensitivity on day 1 and a clinically significant reduction was observed at one week.

Comparison of the effect of shear bond strength with silane and other three chemical presurface treatments of a glass fiber-reinforced post on adhesion with a resin-based luting agent: An in vitro study.

BACKGROUND: Loss of retention has been cited to be the most common cause of the failure of postretained restoration with irreversible consequences when materials with different compositions are in intimate contact at the post/adhesive interface. With this background, a study was conducted to improve the adhesion at the resin phase of fiber posts using silane and other chemical pretreatments. MATERIALS AND METHODS: Hundred glass fiber-reinforced posts were tested with 4 different protocols (n = 25) using silane as a control (Group A) and other three experimental groups, namely, Group B-20% potassium permanganate, Group C-4% hydrofluoric acid, and Group D-10% hydrogen peroxide were pretreated on the postsurface followed by silanization. These specimens were bonded with dual-polymerizing resin-based luting agent, which were then loaded at the crosshead speed of 1 mm/min to record the shear bond strength at the post/adhesive interface. The data were analyzed using one-way ANOVA test for multiple group comparisons and the post hoc Bonferroni test for pairwise comparisons (P < 0.05). RESULTS: Group B showed more influence on the shear bond strength when compared to other protocols, respectively (P < 0.001). CONCLUSION: Alone silanization as a surface treatment did not improve the bond strength. Combination of chemical presurface treatments followed by silanization significantly enhanced the bond strength at the post/adhesive interface.
