Here, we evaluated the utility of an additional CPR sequence in detecting dental pathologies in patients with chronic rhinosinusitis (CRS). (2) Methods: CRS patients who underwent paranasal sinus CT were enrolled retrospectively. The CT images featured three orthogonal sequences and a reconstructed CPR sequence. Additional dental CBCT was performed in patients with pathologies with a strongly suspected odontogenic origin. Dental pathologies detected by CT, CPR, and CBCT were analyzed. (3) Results: A total of 82 CRS patients (37 females and 45 males; mean age 47.3 \u00b1 13.7 years) were included, of whom 23 underwent dental CBCT. In total, 1058 maxillary teeth were evaluated. Compared with paranasal sinus CT, CPR identified greater frequencies of dental pathologies, particularly caries (p &lt; 0.001), periapical lesions (p &lt; 0.001), and fistulae (p = 0.014). CBCT identified greater frequencies of periodontal dental pathologies (p = 0.046) and premolar caries (p = 0.002) compared with CPR. CBCT and CPR detected molar dental pathologies at similar frequencies. (4) Conclusions: CPR could increase the diagnostic rate of odontogenic pathologies compared with standard CT orthogonal views, especially when the sinusitis is caused by caries, periapical lesions, or fistulae. The addition of a CPR sequence allows for simple screening of dental pathologies in CRS patients without a need for additional radiation.<\/jats:p>","DOI":"10.3390\/tomography8050194","type":"journal-article","created":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T04:28:55Z","timestamp":1663648135000},"page":"2330-2338","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Curved Planar Reformation: A Useful Method for Screening Dental Pathologies in Chronic Rhinosinusitis via Paranasal Sinus Computed Tomography"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4124-0222","authenticated-orcid":false,"given":"Wei-Chih","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, College of Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 833, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa Alice","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, College of Medicine, Chiayi Chang Gung Memorial Hospital and Chang Gung University, Chiayi 613, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-Che","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, College of Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 833, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9397-0986","authenticated-orcid":false,"given":"Ching-Nung","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, College of Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 833, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-Chia","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, College of Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 833, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuan-Chung","family":"Fang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, College of Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 833, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4095-5541","authenticated-orcid":false,"given":"Sheng-Dean","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, College of Medicine, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University, Kaohsiung 833, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1216","DOI":"10.1111\/j.1398-9995.2011.02646.x","article-title":"Chronic rhinosinusitis in Europe: An underestimated disease.
