32 SERIES (VIDEO NO 41)

hello everyone this is dr. Amiya from team MDS conquer in this 32 series we are going to discuss about numerical scene oral radiology point number one fill in size for panoramic radiograph is find it well or 6 into 12 inches number to fill him size for little oblique and TMJ uses 5 to 7 inches number three filling size for supplementary is 18 to 12 inches number for swelling size first call radiography 10 to 12 inches number 5 intensifying screen makes image receptor 10 to 60 times more sensitive to x-rays than the door for him alone point number 6 the base material of intensifying screen sees polyester plastic which is about 0.25 mm thick number 7 light emission from lonex trail earth intensifying screens ranges from 375 to 600 nanometers and Peaks sharply 545 nanometers that is a green color number 8 a protective polymer coat less than or equal to 15 micrometers placed over the phosphor layer in intensifying screen for number 9 the pH of activator that is sodium or potassium hydroxide in developing solution is 10 point number 10 developer replenisher consists of 8 ounces of fresh developer per galloon of developing solution it is useful to make 30 periapical or 5 panoramic films per day number 11 the pH of SD fire that is acetic acid in 6 the solution is 4 point 5 point number 12 safe light should have a frosted 15 watt bulb or a clear 7.5 watt bulb number 13 safe light should be at least four feet from work surface area number 14 film handling under a safe flight should be limited to 5 minutes because film emulsion shows some sensitivity when number 15 manual processing time temperature is 60 degree foreign heat and 75 degree foreign heat number 16 master time flies for dental offices of 20 centimeters to 25 centimeters that is of 8 inches to 10 inches number 17 the tank holds 3.8 liters of developer or fixer which is equal to 1 gallon point number 18 here we are going to discuss about crossing temperature and relative development time that is its sixth year degree foreign heat the developing time is of five minutes unless 70 degree foreign heat for and off minutes 72 degree foreign heat 4 minutes 76 degree foreign heat is of three minutes and at 80 degree foreign he the development time is 200 minutes phone number nineteen automatic process requires four to six minutes to develop fix wash and dry a film number twenty a film of great diagnostic value is between point six to three optical density units number twenty one minimal density is called base plus fog and is soft typically point 2 to point 3 number twenty two speed of the film is fourteen to twenty seven point nine reciprocal draw engines point number twenty three speed of a film is twenty eight to fifty five point nine reciprocal draw engines where a speed of F film is 56 to one eleven point land reciprocal dimensions number 25 in ideal radiograph at least two mm of periapical bone must be visibly number 26 when placing a CCD or CMOS sensor remember to account for the two to 4 mm non-imaging area found at the end of sensor point number 27 film not set of film radiographs include 21 radiographs in with 17 or of Perea Pikul and for off bite wings number 28 in parallel onion technique central ray is at 90 degrees to the teeth and receptor whereas in bisecting angle technique central rays 90 degrees to the imaginary bisector for number 30 here we are going to discuss about angulations in the bisecting angle technique for Manx Larry incisors projection is plus 40 degrees and for mandibular incisors the projection is minus 15 degrees for maxillary canine cities of plus 45 degrees and for mandibular canines is minus 20 degrees for mites larry premolars plus 30 degrees and for mandibular premolars minus 10 degrees for maxillary molars the projection is plus 20 degrees and for Magda Blair Mulas the projection is minus 5 degrees for number 31 in between projection beam is angulated plus 7/2 plus 10 degrees vertically to preclude the overlap of the cusps onto the occlusal surface point number 32 the molar piping receptor is placed 1 or 2 mm beyond the most distal erupted molar that's it for today's session guys this is the third video I made on numeric dates in oral radiology go and said the first two videos to note on all these points and keep on revising them all the points discussed here are very important in need and aims point of view all the best thank you
