I'm a dental gp .. I have a 21 years old female patient present to my clinic complaining of pain in the posterior upper teeth ( some times she localized them at 15,14,24,26 ) and its less painful in the lower posteriors .. Pain initiated with thermal,sweets and mastication. Duration of pain half a minute to 2 minutes . Patient complaining for more than 5 years .. Diagnosed as hypersensitivity before 4 years and she used sensodyne for 2 years with improvement up to 60% .. Clinical examination shows a skeletal class III , scissor bite , no recession or exposed dentin and a small fissure caries in 47,26,16 .. Now I put the patient on sensodyne todays is the 5th day and she say there is improvement more than 80% at the first 3 hours after brushing ..
I'm asking what could be the cause of the pain ? Is it the hypersensitivity or there is no hypersensitivity its the small fissure caries ..?
And could it be a very small fissure caries for more than 5 years causing the same complain ?
