{"doi":"10.1016/j.pacs.2022.100408","title":"Posterior photoacoustic/ultrasound imaging of the periodontal pocket with a compact intraoral transducer","abstract":"Periodontitis is a public issue and imaging periodontal pocket is important to evaluate periodontitis. Regular linear transducers have limitations in imaging the posterior teeth due to their geometry restrictions. Here we characterized a transducer that can image the posterior teeth including assessment of periodontal pockets via a combination of photoacoustic and ultrasound imaging. Unlike conventional transducer design, this device has a toothbrush-shaped form factor with a side-view transducer to image molars (total size: 1 ×1.9 cm). A laser diode was integrated as the light source to reduce the cost and size and facilitates clinical transition. The in vivo imaging of a molar of a periodontal patient demonstrated that the transducer could image in the posterior area of gum in vivo; the value determined by imaging was within 7 % of the value measured clinically.","journal":"Photoacoustics","year":2022,"id":266740,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":9,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9571,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":774399,"name":"Reza Khazaeinezhad","orcid":null,"position":1,"is_corresponding":false},{"id":314939,"name":"Ali Hariri","orcid":"0000-0003-0306-5013","position":2,"is_corresponding":false},{"id":808125,"name":"Baiyan Qi","orcid":"0000-0002-3386-9541","position":3,"is_corresponding":false},{"id":515252,"name":"Casey Chen","orcid":"0000-0002-0331-0181","position":4,"is_corresponding":false},{"id":238364,"name":"Jesse V.
