Comparative efficacy of three deproteinizing agents on the shear bond strength of pit and fissure sealant: An in vitro study
Saranya P Thankachan, Tharian B Emmatty, Bijimol Jose, Kumar Kavita Krishna, Joby Peter, John Joseph Methippara, Ronin Sebastian

Objective: The objective of this study was to evaluate and compare the shear bond strength (SBS) of pit and fissure sealant with and without deproteinization with agents such as 5% NaOCl, papain gel, and bromelain gel. Materials and Methods: In this in vitro study, 60 premolar teeth were divided into four groups of 15 teeth each. In control Group 1, enamel was etched for 60 s with 37% phosphoric acid and rinsed with water. In Group 2, deproteinizing agent 5% sodium hypochlorite was applied for 60 s before acid etching. In Group 3, deproteinizing agent papain gel was applied for 60 s before acid etching. In Group 4, deproteinizing agent bromelain gel was applied for 60 s before acid etching. Following this, Clinpro 3M ESPE pit and fissure sealant disc was built on the enamel buccal surface of each tooth. Samples were then tested for SBS using Universal Testing Machine after storage in distilled water for 24 h. Results: The mean SBS was highest for Group 4 and lowest for Group 1. SBS was significantly higher in the bromelain gel group, followed by the papain gel group (P < 0.001), 5% NaOCl group (P < 0.001), and control group (P < 0.001). Conclusion: Among deproteinizing agents, deproteinization when carried out with bromelain gel showed effective bond strength and lowest for the control group.

Evaluation of antimicrobial action, pulp tissue dissolution, and smear layer removal of an experimental irrigant combining Salvadora persica and sodium hypochlorite with and without ultrasonic activation: An in vitro study

Aim: To evaluate the pulp tissue dissolution, antimicrobial action, and smear layer removal using an experimental irrigant combining Salvadora persica and sodium hypochlorite (NaOCl) with and without ultrasonic activation in comparison to standard irrigation protocol of NaOCl and ethylenediamine tetraacetic acid (EDTA) with and without ultrasonic activation. Materials and Methods: Pulp tissue dissolution - Pulp tissue weighing 0.9 g was dissolved in each experimental Group G1: 5 ml of 5% NaOCl, G2: G1 + ultrasonic activation, G3: 5 ml 5% NaOCl + 40% S. persica, G4: G3 + ultrasonic activation and weighed after 1, 5, and 10 min. The difference in weight of the tissue sample was assessed. Smear layer removal and calcium/phosphate (Ca/PO4) ratio - G1: 5 ml of 5% NaOCl, saline, 1 ml of 17% EDTA, G2: G1 + ultrasonic activation, saline, 17% EDTA, G3: 5 ml 5% NaOCl + 40% S. persica G4: G3 + ultrasonic activation. Each tooth was then split longitudinally and subjected to scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM-EDX) analysis. Antibacterial Activity- assessed against Enterococcus Faecalis. Statistical Analysis: SEM, pulp tissue dissolution and antimicrobial efficacy – Kruskal–Wallis and post hoc Mann–Whitney EDX – ANOVA and Tukey's honestly significant difference post hoc analysis. Results: Pulp dissolution by G3 and G4 was better. However, there was no statistically significant difference between the groups (P > 0.05). Experimental combination performed better in terms of smear layer removal, showed higher amount Ca/PO4 in EDX analysis, but the difference was not statistically significant between the groups (P > 0.05). G2 showed maximum antimicrobial efficacy compared to all groups but not statistically significant (P > 0.05). Conclusions: The combined formulation of 5% NaOCl + 40% S. Persica was as effective as conventional protocol and ultrasonic activation improved its efficacy.

Autotransplantation for the correction of unfavorably impacted canines
T Lishna Karalikkattil, Muhammed Shaloob, Asni Shebad, PG Francis
July-September 2022, 9(3):78-81
The canine is diagnosed as impacted when its normal eruption time is significantly exceeded compared to the contralateral canine or the premolars. This case report presents, a female patient 14 years old with bilaterally impacted maxillary canines, retained maxillary deciduous canines, and proclination and spacing of the upper and lower anteriors and peg laterals. The treatment objective was to create a more ideal overjet and overbite relationship, place the impacted canines into position, and improve facial profile. Fixed orthodontic treatment was done with PEA “0.022 × 0.028” ORMCO, MBT prescription. After leveling, aligning, and space closure, extraction of bilaterally retained deciduous canines and autotransplantation of the unfavorably impacted canines were done. To enhance esthetics, composite restoration was done on the peg laterals. The total treatment time was 2 ½ years and the treatment objectives were achieved due to excellent patient cooperation. Facial harmony was good, and proclination and spacing were corrected.

Endo–perio lesions: A dilemma
Shirish Kujur, Vineeta Gupta, VS Sreeraj, Shweta Ratre, Varsha Soni
July-September 2022, 9(3):86-89
Endo–perio lesions are a common finding in dental practice. Progression of an endodontic lesion, if allowed leads to periodontal involvement or vice versa. This is a case series of two cases of the endodontic lesion with periodontal involvement that has been treated by performing root canal treatment followed by flap surgery. The tooth was first endodontically treated that was followed by periodontal treatment. Six months postoperatively, there was a significant gain in clinical attachment level. Radiographically, there was a significant amount of bone fill observed.

Diode laser excision of pyogenic granuloma
Shirish Kujur, Vineeta Gupta, VS Sreeraj, Rashmi Christin Kerketta, Bhumika Jhawar
July-September 2022, 9(3):82-85
Pyogenic granuloma is a commonly occurring inflammatory hyperplasia of the skin and oral mucosa in females. It is a misnomer that is characterized histologically by angiomatous proliferation rather than a granulomatous lesion. This tumor-like growth is considered to be nonneoplastic in nature and has a varied clinical presentation. We present one such case of pyogenic granuloma, which was excised with a diode laser along with a relevant review of the literature.
