Plot of sen­si­tiv­ity to pain of a front tooth de­ter­mined by cold stimu­lus ap­pli­ca­tion (so-called bene­fi­cial time of cold stimu­lus) of 3 test sub­jects on 3 dif­fer­ent days. De­ter­mi­na­tion of the wave of pain oc­curred in in­ter­vals of 15-30 min­utes. The val­ues are shown in per cent of the in­di­vid­ual daily means. The rhythm of the sen­si­tiv­ity to pain is the same as the one which forms the sleep cy­cles dur­ing a night’s sleep.

(According to POLLMANN and HILDEBRANDT 1982)





Illustration 3

Semi-quan­ti­ta­tive pres­en­ta­tion of the rhythm of the sides of the nose of 4 peo­ple in the course of 24 hours. The full swing of the curves shows that approx. 80% of the to­tal res­pi­ra­tory air is in­haled, due to the nasal mu­cous mem­brane going down on one side, through only one side of the nose.
MOZ = mean local time.
