Efficacy of methylene blue and curcumin mediated antimicrobial photodynamic therapy in the treatment of indirect pulp capping in permanent molar teeth.

Purpose: This study aimed to evaluate the adhesive bond strength and antibacterial efficacy of methylene blue (MB)-mediated antimicrobial photodynamic therapy (aPDT) and curcumin (CUR)-mediated aPDT versus the conventional disinfectants, such as chlorhexidine gluconate (CHX) gel and sodium hypochlorite (NaOCl), for indirect pulp capping (IPC) treatment of permanent molars.

Methods: One Hundred grossly carious human permanent molars were collected through non-traumatic extraction. All specimens were embedded in polyvinyl cross-sections to the cemento-enamel junction.

Delphi consensus on research priorities in tobacco use and substance abuse in Saudi Arabia.

This is the first study to develop research priorities in tobacco use and substance abuse in Saudi Arabia. Health personnel and community volunteers participated in a national internet survey using the Delphi method. In Round 1, 75 experts identified 33 research priorities.

Implementation of Cigarette Plain Packaging: Triadic Reactions of Consumers, State Officials, and Tobacco Companies-The Case of Saudi Arabia.

Objectives: In August 2019, Saudi Arabia started implementing plain packaging for cigarettes. Three months later, an opposing campaign on twitter using an Arabic hashtag "the new smoke" gained momentum amongst smokers. The purpose of this study is to document this opposing campaign's timeline and describe consumers, government, and tobacco industry rhetoric.

Influence of platelet rich fibrin on post-extraction socket healing: A clinical and radiographic study.

Aim: The aim of this study was to evaluate clinically and radiographically, extraction socket healing using autologous platelet rich fibrin (PRF).

Materials And Methods: Twenty-four subjects needing single tooth simple extractions were selected. Twenty-four extraction sockets were divided into test group (PRF, n = 12) and control group (blood clot, n = 12).

Three-dimensional printing of bone repair and replacement materials: impact on craniofacial surgery.

Solid freeform fabrication techniques such as direct write technology can be used to fabricate tissue-engineering scaffolds in 3 dimensions with high levels of reproducibility and precision. These can comprise complex structures made of osteoconductive, remodelable lattices to conduct bone ingrowth and solid barriers to prevent soft tissue invasion. As such, they act as a combination of bone graft and barrier membrane.
