Both implant and pre-implant surgery have increased their incidence. It is necessary, therefore, to address sinonasal pathology (SN) related to dental pathology (DP) or dental treatments (DT) from an interdisciplinary point of view by establishing collaborative working groups between Dentistry (DEN) and Otolaryngology (ENT), as well as by developing registries and establishing coordinated diagnosis and treatment protocols of sinonasal pathology. The aim of this study is to design a useful classification of SN pathology associated with DP or DT to record information of DEN and ENT. Material and methods: Bibliographic review and design of a classification system of SN, DP and DT pathology. Results: Six categories are described in our system: 0- absence of SN pathology and DP; 1 and 4- patients with DP associated or associated with SN pathology, respectively; 2 and 5- patients with DT not associated or associated with SN pathology, respectively and 3- patients with SN pathology without DP. The classification has applications in diagnosis (association and possible causal relationship between the SN pathology and DP) and in the treatment of NS and DP simultaneously or sequentially. Conclusions: The classification proposed integrates the presence or absence of DP or DT, and its causal association or the lack of it with SN pathology. Moreover, it facilitates the communication between DEN and ENT and eases the registration of information and the planning of dental, implant and pre-implant treatments.","PeriodicalId":18742,"journal":{"name":"Minerva stomatologica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44710310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The temperature changes recorded were also correlated with the residual dentin thickness.\u0000\u0000\u0000METHODS\u0000A sample of 32 human extracted molars was selected. The teeth were endodontically treated and prepared with prosthetic round chamfer preparation. Then, they were inserted in plaster cubes up to the cement-enamel junction, leaving the apical portion pervious for inserting the thermocouple probe. The conventional technique, which involves the use of a high-speed contra-angle handpiece, was compared with an ultrasonic method (Crown Prep, Mectron, Carasco, Italy). For margin repositioning and finishing, two walls were randomly selected for each tooth: one was included in the test group and cut with the piezoelectric instrument (Multipiezo Touch TipHolder DB2, Mectron, Carasco, Italy), the other one was inserted in the control group and cut with the high speed contra-angle handpiece (Kavo, Biberach, Germany). To standardize the operator-dependent parameters, it was used a mechanical arm controlled by a computer.These parameters were the pressure exerted on the dental wall, the cutting length and the time required for margin repositioning and finishing. For both test and control group, test phase consisted in a first stage of margin repositioning using an ultrasound tip or a diamond bur with a greater granulometry (120 μm for the ultrasound tip and 125 μm for the diamond bur), followed by a second finishing step conducted by an ultrasound tip or a diamond bur with smaller granulometry (60 μm for the ultrasound tip and 30 μm for the diamond bur). During these stages the intrapulpal temperature was recorded thanks to a thermocouple. Before and after these steps, the thickness of the remaining dental walls was measured with a caliber.\u0000\u0000\u0000RESULTS\u0000The average pulpal temperature increase was 5,03°C with a standard deviation of 0,98 for the ultrasonic preparation (test group) and 3,55°C with a standard deviation of 0,95 for the conventional technique (control group). The difference was statistically significant (p value < 0,001). However, neither of the instruments reached the critical level of 5.5°C reported in the literature. The mean initial dentin thicknesses was 1,82 mm (S.D. 0,47) for the control group and 1,59 mm (S.D. 0,54) for the test group but the analysis of the residual dentin thicknesses revealed a greater reduction of the walls worked up with high speed contra-angle handpiece (mean 0,9 mm, S.D. 0,5), which was therefore more aggressive than the ultrasonic instrument (mean 1,1 mm, S.D 0,5). A very weak negative correlation was present between the thickness of the wall at baseline and the increment of temperature.\u0000\u0000\u0000CONCLUSIONS\u0000Within limitations of this study, temperature increasing of ultrasonic instruments shows a statistical difference related to rotary ones.
