吃對食物對口腔健康也有幫助。對此，牙醫師蔡雅藍分享4款有益牙齒的秋季當季食材，包括蘋果、胡蘿蔔、南瓜，以及堅果。其中她提到，蘋果的纖維質地就像天然牙刷，除了能促進唾液分泌，還有助於保持牙齒潔白；另外，南瓜也含有大量纖維，具清潔牙齒和促進消化的作用。

醫師蔡雅藍在個人粉專發文，盤點以下4款有益牙齒的天然食材，值得納入日常食物清單：

1、蘋果：咀嚼蘋果能促進唾液分泌，幫助沖刷口腔中的食物殘渣與細菌，從而減少牙菌斑形成。此外，蘋果的纖維質地就好比天然牙刷，可輕輕擦拭牙齒表面，有助於保持牙齒潔白。

The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.
