Introduction: Fractographic analysis is performed by observing, measuring, and interpreting the fracture surface topography that can determine many features of the microstructure of materials and the mechanics of the fracture. This study was planned to put through investigation, marginal fit and ceramo-metal shear bond strength with fractographic analysis of the debonded surfaces. The aim of this study was to assess the marginal fit, ceramo-metal shear bond strength of sinter cast gold and to analyze the debonded sample by fractography. Materials and Methods: A total of 5 sinter cast gold copings were prepared on a stainless master die resembling a maxillary 1st pre-molar to receive a ceramo-metal restoration. Each of the copings were, then, assessed for marginal fit before and after ceramic firing. Also, a total of 5 ceramo-metal discs were fabricated for testing shear bond strength at the metal-ceramic interface. The samples were subjected to increasing shear load on a Universal Testing Machine with crosshead speed of 0.002mm/sec. The load at which, the samples debonded completely, was noted and the samples put-to fractographic analysis. Results: The mean marginal fit found in this study for sinter cast gold before ceramic firing was measured to be 11.5 μm with a standard deviation of ±4.64 μm and after ceramic firing was found to be 9.38 μm with a standard deviation of ±3.57 μm. The average shear bond strength at the sinter cast gold ceramic interface was 18.216 MPa. The fractographic analysis showed the globular microstructure of sinter cast gold on sintering, adhesive, and mix-mode type of fracture with the presence of both gold and ceramic. Conclusion: The marginal fit observed before and after ceramic firing was within clinically acceptable range while the ceramo-metal shear bond strength between sinter cast gold and ceramic was found to be inadequate.

Background: Endodontic-periodontal lesions are described as the lesions due to inflammatory products found in varying degrees in both pulp and periodontal tissues. In all cases of concurrent periodontal and pulpal disorders, the clinician must determine whether the existing tissue change originated from one or both processes so that appropriate treatment could be initiated. Aims: The aim of the present randomized controlled clinical trial was to evaluate and compare the two treatment approaches for the treatment of primary endodontic lesions with secondary periodontal involvement, i.e., root canal treatment (RCT) with RCT and periodontal flap surgery. Subjects and Methods: In this study, twenty cases aged between 18 and 55 years with good systemic health diagnosed as cases of primary endodontic lesion with secondary periodontal involvement were selected for the study. In ten cases, only RCT was performed (control group), and in another ten, after 1 month of completion of RCT, periodontal flap surgery was performed (test group). The patients were evaluated for changes in the gingival index, plaque index, gingival bleeding index, probing depth (PD), and relative attachment level (RAL) at baseline, 1 month, and at 4 months postoperatively. Results and Conclusion: Results showed statistically significant (P < 0.05) reduction from baseline to 1 and 4 months in the PD and gain in RAL both on intergroup and intragroup comparison. Thus, from the results of the study, it could be concluded that both treatment approaches revealed a significant improvement in the PD reduction and attachment level gain 4 months postoperatively. However, test group showed a significant difference in the reduction of PD and gain in attachment level.

Background: Periodontitis is an inflammatory disease of multifactorial origin affecting the supporting tissues of the periodontium. Photodynamic therapy (PDT) involves the photosensitizer dye and a light source to induce reactive oxygen species (singlet oxygen) and causes destruction of microorganisms. Aim: The aim of this study was to compare the efficacy of PDT with scaling and root planing (SRP) and also to compare the efficacy of two different concentrations of photosensitizer (methylene blue 0.005% and 0.01%) in the treatment of chronic periodontitis. Materials and Methodology: Forty-five patients affected by moderate-to-severe chronic periodontitis were included in the study and were divided into three groups. The clinical parameters, plaque index (PI), gingival index (GI), and probing pocket depth were recorded at baseline, 1 month, and 3 months of time interval. After SRP, PDT was performed using methylene blue dye (0.005% and 0.01%) and diode laser with 665 nm wavelength for 60 s. Results: At 1 and 3 months after treatment, there were no statistically significant differences between the groups with regard to reduction in PI, GI, and probing pocket depth in all the three groups (P > 0.05). Conclusion: The additional application of a single episode of PDT to SRP failed to result in an additional improvement in terms of reduction in plaque score, GI score, and pocket probing depth.

Aim: This in vitro study was conducted with an aim to compare apical leakage between root canals filled with Gutta-percha/AH Plus and Resilon/Epiphany SE Sealer using cold lateral condensation technique. Materials and Methods: Eighty recently extracted human mandibular permanent premolars with straight roots with single canals were used in this study. Out of eighty samples, 40 were randomly divided into 2 experimental groups of 20 teeth each (n = 20). Samples in Group I were obturated with cold lateral condensation technique using Gutta-percha/AH Plus, in Group II were obturated by cold lateral condensation using Resilon/Epiphany SE Sealer. Forty teeth saved as controls positive (n = 20) and 20 negative (n = 20). Results: When comparison of leakage was done between Group I (Gutta-percha/AH Plus-cold lateral condensation) and Group II (Resilon/Epiphany SE Sealer-cold lateral condensation) by Mann–Whitney U-test, P = 0.001, which is statistically significant (P < 0.05). Conclusion: Gutta-percha exhibited an overall significantly lower percentage of apical dye penetration.

Background: Plants have been the major source of medicine since time immemorial. Turmeric, a rhizome of Curcuma longa, is a herb known for its medicinal properties and is more acceptable and viable option for a common man. Objective: To evaluate the efficacy of golden paste, a combination of turmeric, virgin coconut oil, and black pepper as a monotherapy in treating gingivitis. Methodology: 30 patients within the age group of 25-45 years diagnosed with chronic gingivitis and were administered with golden paste as monotherapy in comparison to scaling and golden paste by using a split mouth study design. Bleeding index and gingival index were evaluated at baseline, 14 days and 21 days. Results: A significant reduction in GI and BI is seen in scaling and golden paste group in comparison to golden paste used as monotherapy.

Background: This study is an effort to find the appropriate edge profile and surface treatment during repair of the fractured dentures, which can provide long-lasting results and can prevent the recurrence of the fracture. Objectives: The objective of this study was to evaluate the transverse strength of butt versus bevel edge profile with surface treatment and reinforced with glass fibers using autopolymerizing acrylic resin and to compare the samples surface treated with ethyl acetate and reinforced with glass fibers on butt and bevel edge profile. Materials and Methods: This study consisted of a sample size of 105, wherein 15 unfractured heat polymerizing acrylic resin samples were used as a control, 45 repaired samples of bevel edge profile, and 45 repaired samples of butt edge profile. These samples were further subdivided into groups and repaired using autopolymerizing acrylic resin, glass fiber-reinforced autopolymerizing acrylic resin, and with glass fiber-reinforced autopolymerizing resin surface treated with ethyl acetate, respectively. The repaired samples were tested for transverse strength on an Instron testing apparatus. The P value set at 0.05. Analysis was done using analysis of variance and Tukey's honest significant difference test. Transverse strength of samples, repaired after ethyl acetate surface treatment, was higher when compared to untreated samples (P = 0.001). Transverse strength of samples, repaired with ethyl acetate surface treatment and glass fiber reinforcement material, was the highest (P = 0.001). Conclusion: Ethyl acetate surface-treated bevel edge profile acrylic strips repaired using glass fiber-reinforced autopolymerizing acrylic resin showed greater transverse strength.

Fracture of anterior teeth poses functional as well as esthetic implications. Subgingival fractures are often treated by extraction of tooth followed by implant placement or a conventional fixed partial denture due to absence of adequate ferrule at the fracture site. Orthodontic extrusion/forced eruption can aid in the traction of fractured plane coronal to the gingival level, providing enough tooth structure for prosthetic rehabilitation. Since the surrounding periodontium also remodel during tooth extrusion, periodontal intervention may be required for their recontouring leading to a more esthetic final result. Endodontics need to be carried out when the pulp is involved due to traumatic injury. This kind of multidisciplinary approach can save many teeth with subgingival fracture from extraction. It can save the patient from the stress of extraction, especially at young age.

In modern clinical practice, successful treatment of a compromised situation demands multidisciplinary approach. Increasing esthetic demand in adult patients may require a close interaction of orthodontist and periodontist and to work together to provide the best treatment possible to the patient. The present case report highlights the team approach for successful management of malocclusion in an adult patient with compromised periodontal condition.
