Analysis of the Radiological Changes of the Sinus Membrane Using Cone Beam Computed Tomography and Its Relationship with Dental Treatments. A Retrospective Study. Biology (Basel). 2022 Jan 20;11(2):1652079-773710.3390/biology11020165https://hdl.handle.net/20.500.14352/93819The aim of this study was to identify the most relevant dental factors and iatrogenic causes in the development of pathological changes to the sinus membrane and to analyse their possible influence on the development of odontogenic sinusitis. A descriptive, observational study was designed, with 276 patients who had been evaluated via cone beam computed tomography, analysing possible sinus thickening factors, such as apical infections, endodontic treatments, periodontitis, radicular cysts and impacted teeth, as well as iatrogenic factors caused by implant treatments or the development of oroantral communications produced during tooth extraction manoeuvres. Among the dental factors, periodontitis (47.1%), apical pathology (23.5%) and endodontic treatments (23.1%) were the predominant causes of sinus membrane thickening that most frequently produced an occupancy between 2 and 10 mm. Regarding the implant treatments, the placement of implants through the floor of the maxillary sinus was the main cause (9.8%), followed by sinus elevation techniques (6.2%). Dental extraction was the first cause of oroantral communication (5.0%), being the procedure that caused the greatest thickening of the sinus membrane. This study highlights the importance of dental treatments and iatrogenic factors in sinus pathology, and the need for diagnostic interrelations between the different specialists who address this pathology.engAttribution 4.0 Internationaljournal articlehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC8869354/pdf/biology-11-00165.pdf35205032https://www.mdpi.com/2079-7737/11/2/165open access616.216-002616.314Cone beam computed tomography (CBCT)Dental factorsIatrogenic factorsOdontogenic sinusitisSinus membrane thickeningOdontología (Odontología)Odontología (Medicina)32 Ciencias Médicas3213.13 Ortodoncia-Estomatología
