In this paper, we report on developing a POC technology based on optical fiber sensors as a promising marker, to the best of our knowledge, to detect the role of salivary pH in periodontitis diagnosis and support dentists’ inspection. The optical fiber sensor based on a drop-like structure was fabricated by bending single-mode fiber (SMF) into a section of a thin capillary tube. In this work, firstly, the performance of the proposed sensor towards different pH levels ranging from 1 to 7 was experimentally investigated. Experimentations showed that the pH sensor responded to various pH levels with a calibration curve sensitivity of −2.075 nm/pH and a high linearity of 0.985. Then, 66 patients were enrolled in this study and divided into two groups according to clinical outcomes: Group A with clinically healthy periodontium and Group B with chronic periodontitis. The real saliva from each patient was collected, and the salivary pH was evaluated immediately using the aforementioned proposed sensor. The experimental results show that Group A and Group B salivary pH mapping ranged from 6.5 to 7.3 and 5.5 to 6.4, respectively.
