Objective: This study was performed to evaluate the ability of four different electric power toothbrushes to remove dental plaque on a three-dimensional (3-D) study model. Methods: A 3-D, 360-degree model of 32 human teeth was made of polyester (ELEGOO Inc.). Then, eight photos were made (four teeth at a time) from each quadrant and used as the negative control group (0% plaque). Then plaque-like color spray chalk were added and cured on the teeth model; photos were made and used as the positive control group (100% plaque). The 3-D model of the teeth was placed on a rotatable axis and immersed in a basin mimicking the composition of artificial saliva and toothpaste. An apparatus with a mechanical arm was made to hold the toothbrushes during the plaque removal process and control the force of brushing. Twenty-four toothbrushes were prepared and divided into four experimental groups of 6 (n=6) including 1) Philips, 2) Oral-B, 3) Quip, and 4) Waterpik. Toothbrushing was performed for 2 minutes. After brushing, photos were taken, and the percentage of plaque removal was measured by using the ImageJ software. Data were analyzed by Kolmogorov–Smirnov, ANOVA, and post hoc Tukey tests. Results: The highest plaque removal values were observed in the Philips group, and the lowest were seen in the Quip group. Significant differences were only recorded between the values of Philips and the other groups (p<0.05). Conclusion: Within 2 minutes of brushing time, none of the power toothbrushes could completely remove artificial dental plaque.

Angiogenesis and the prevention of alveolar osteitis: a review study
Mohammad Ali Saghiri,Armen Asatourian,Nader Sheibani 대한구강악안면외과학회 2018 대한구강악안면외과학회지 Vol.44 No.3
Angiogenesis is one of the essential processes that occur during wound healing. It is responsible for providing immunity as well as the regenerative cells, nutrition, and oxygen needed for the healing of the alveolar socket following tooth extraction. The inappropriate removal of formed blood clots causes the undesirable phenomenon of alveolar osteitis (AO) or dry socket. In this review, we aimed to investigate whether enhanced angiogenesis contributes to a more effective prevention of AO. The potential pro- or anti-angiogenic activity of different materials used for the treatment of AO were evaluated. An electronic search was performed in the PubMed, MEDLINE, and EMBASE databases via OVID from January 2000 to September 2016 using the keywords mentioned in the PubMed and MeSH (Medical Subject Headings) terms regarding the role of angiogenesis in the prevention of AO. Our initial search identified 408 articles using the keywords indicated above, with 38 of them meeting the inclusion criteria set for this review. Due to the undeniable role of angiogenesis in the socket healing process, it is beneficial if strategies for preventing AO are directed toward more proan-giogenic materials and modalities.
