Evaluation of pain, disruptive behaviour and anxiety in children aging 5-8 years old undergoing different modalities of local anaesthetic injection for dental treatment: a randomised clinical trial.

To evaluate the influence of different local anaesthetic techniques in pain, disruptive behaviour and anxiety in children´s dental treatment. This was a randomised and parallel clinical trial. The sample consisted of 105 children (5-8 years old) that were divided into three groups ( = 35) according to the anaesthetic technique: conventional anaesthesia (CA); vibrational anaesthesia (VBA); computer-controlled local anaesthesia delivery (CCLAD).

Does computerized anaesthesia reduce pain during local anaesthesia in paediatric patients for dental treatment? A systematic review and meta-analysis.

This systematic review and meta-analysis analysed whether pain and disruptive behaviour can be decreased by the use of computerized local dental anaesthesia (CDLA) in children. The literature was screened to select randomized clinical trials that compared computerized and conventional anaesthesia. The primary outcome was pain perception during anaesthesia; the secondary, disruptive behaviour.

In vitro antimicrobial evaluation of toothpastes with natural compounds.

Objectives: This in vitro study evaluated the antimicrobial effects of commercial toothpastes containing natural compounds.

Materials And Methods: The study groups were divided based on the natural compound present in the toothpaste composition: Sorbitol (I), tocopherol (II), mint (III), cinnamon/mint (IV), propolis/melaleuca (V), mint/açai (VI), mint/guarana (VII), propolis (VIII), negative control (IX), and the positive control (X). The antimicrobial properties of the toothpastes were tested using the disk diffusion method against oral pathogens: Streptococcus mutans, Pseudomonas aeruginosa, and Enterococcus faecalis.
