Noninvasive Ventilation in the Management of Respiratory Failure Due to COVID-19 Infection: Experience From a Resource-Limited Setting.

Objective: To study the role of noninvasive ventilation (NIV) in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV2) related acute respiratory failure (C-ARF).

Patients And Methods: Patients with C-ARF managed on NIV were categorized as NIV success or failure (death or intubation). Factors associated with failure were explored using regression analysis and expressed as odds ratio (OR) with 95% CI.

Comparing the Efficacy of Twin Mix and Lidocaine for Inferior Alveolar Nerve Blocks in Patients With Symptomatic Irreversible Pulpitis.

This randomized, active-controlled, double-blind, prospective clinical trial evaluated the anesthetic efficacy of 2% lidocaine with 1:200,000 epinephrine versus an admixture of 2% lidocaine with 1:200,000 epinephrine and 1 mL of 4 mg dexamethasone (Twin mix) for inferior alveolar nerve blocks (IANBs) in patients with symptomatic irreversible pulpitis (SIP) of the mandibular molars. Seventy-eight patients with SIP of mandibular molars were randomly allocated to the 2 groups of 39 subjects. All patients were required to have profound lip numbness within 10 minutes of local anesthetic deposition.

Evaluation of alpha-adrenomimetic agents for gingival retraction: A randomized crossover clinical trial.

Context: The displacement of the gingiva around the tooth allows proper access during preparation, precise impression taking, and cementation procedures that has a direct bearing on the health of the periodontium. Several methods and agents are used for this purpose.

Aims: The primary aim of the study was to clinically evaluate the efficacy of naphazoline as a gingival retraction agent.

Comparative evaluation of effects of natural antioxidants on the shear bond strength of composite resin to bleached enamel.

Context: The use of antioxidants immediately after bleaching showed increased bond strength.

Aims: This study aimed to compare the effects of natural antioxidants on the shear bond strength of composite resin to bleached enamel.

Materials And Methods: Fifty extracted single-rooted upper incisors were decoronated by sectioning the roots 2 mm below the cementoenamel junction, and then, crowns were embedded in autopolymerizing acrylic resin block (3.

Stress distribution in endodontically treated abfracted mandibular premolar restored with different cements and crowns: A three-dimensional finite element analysis.

Context: Noncarious cervical lesions may penetrate the pulp and require root canal treatment followed by crown placement. Such teeth may be susceptible to fracture, especially at the cervical area.

Aims: To estimate which combination of restorative material and crown resulted in homogenous stress-strain distribution of endodontically treated abfracted mandibular premolar using three-dimensional finite element model (FEM).

The Effect of Coconut Oil pulling on Streptococcus mutans Count in Saliva in Comparison with Chlorhexidine Mouthwash.

Objectives: Oil pulling is an age-old practice that has gained modern popularity in promoting oral and systemic health. The scientific verification for this practice is insufficient. Thus, this study evaluated the effect of coconut oil pulling on the count of Streptococcus mutans in saliva and to compare its efficacy with that of Chlorhexidine mouthwash: in vivo.

Regenerative endodontics--Creating new horizons.

Trauma to the dental pulp, physical or microbiologic, can lead to inflammation of the pulp followed by necrosis. The current treatment modality for such cases is non-surgical root canal treatment. The damaged tissue is extirpated and the root canal system prepared.

Comparative evaluation of voids present in conventional and capsulated glass ionomer cements using two different conditioners: an in vitro study.

This in vitro study evaluated the presence of voids in powder-liquid and capsulated glass ionomer cement. 40 cavities were prepared on root surfaces of maxillary incisors and divided into four groups. Cavities were conditioned with glass ionomer cement liquid (GC Corporation, Tokyo, Japan) in Groups 1 and 3 and with dentin conditioner (GC Corporation, Tokyo, Japan) in Groups 2 and 4.

The comparison of the effects of different whitening toothpastes on the micro hardness of a nano hybrid composite resin.

Aim: The aim of this study was to compare the micro hardness of a nanohybrid composite resin after brushing with two herbal and one non-herbal whitening toothpastes.

Materials And Methods: We divided Eighty disk-shaped specimens of a nanohybrid composite (Tetric N Ceram, Ivoclar Vivadent, Asia) into 4 groups of 20 specimens each: Groups A, B, C, and D. Group A was control, Group B was brushed with Colgate total advanced whitening (Colgate-Palmolive (India) Limited), Group C with Salt and Lemon, Dabur (Dabur International Limited, Dubai, UAE), and Group D with HiOra Shine, Himalaya (The Himalaya Drug Company, India).

In Vitro Evaluation of the Antimicrobial Efficacy of Four Endodontic Biomaterials against Enterococcus faecalis, Candida albicans, and Staphylococcus aureus.

Root canal sealers that possess good antimicrobial property can prevent residual and recurrent infection and contribute to successful endodontic therapy. This study evaluated the antimicrobial activity of four endodontic sealers, AH Plus, Tubliseal EWT, EndoRez, and iRoot SP, against three different microorganisms, E. faecalis, C.

Restoration of endodontically treated molars using all ceramic endocrowns.

Clinical success of endodontically treated posterior teeth is determined by the postendodontic restoration. Several options have been proposed to restore endodontically treated teeth. Endocrowns represent a conservative and esthetic restorative alternative to full coverage crowns.

Grape seed extract as a potential remineralizing agent: a comparative in vitro study.

Objective: Remineralization is an effective treatment that may stop or reverse early tooth decay. Grape seed extract (GSE) is the potential remineralizing agent under investigation.

Materials And Methods: Sound human tooth sections were obtained from the cervical portion of the root and stored in demineralizing solution at 37°C for 96 hours to induce artificial root caries lesions.
