Description
Technical field
The present invention relates to a kind of model device for dynamic detection of root canal flushing effect and detection method thereof, belong to oral medical experimental model apparatus or stomatology field.
Background technology
Dental pulp disease and periapical disease are modal oral cavity chronic bacillary, infectious disease, root canal therapy is the effective method of treatment dental pulp disease and periapical disease, root canal effectively promotes the healing of periapical lesion by the effective microorganism that reduces in the root pipe of mechanical-chemical preparation.Because the root canal morphology complexity, its anatomic form is different because of tooth, and is very complicated.Studies show that having preparation techniques now can't prepare whole root canal system, nearly 61% area can't be prepared the apparatus contact, these can't have a large amount of microorganisms and dentin chip in preliminary dead angle, therefore root canal irrigation can effectively be removed dentin chip and infectious agent in the root pipe by chemosterilization-mechanical flushing action, and an important supplementary function is played in preparation to root canal appliance.
The efficient of root canal irrigation mainly depends on the disinfective action and the mechanical erosion effect of root canal irrigation liquid, and the disinfective action of root canal irrigation liquid is removed microorganism in the root pipe, Chow (J Endod1983 by microbial action in root canal irrigation liquid and the root pipe; 9:475-9) studied the flush efficiency of different root canal disinfection liquid, the result shows that the type of mechanical flushing action beguine pipe flushing liquor is an even more important factor.Therefore when in the efficient of research root canal irrigation liquid, the hydrodynamics of root canal irrigation should take into full account.Influence the fluid boundary of efficient of root canal irrigation and character factor have following some, the geometry of root pipe, the diameter of Syringe needle Irrigator, Syringe needle Irrigator enter the degree of depth of root pipe, the root canal morphology after the preparation, the speed of root canal irrigation, the design of Syringe needle Irrigator.Above-mentioned factor plays significant effects to root canal irrigation efficient.Because above factor various combination has got up to form different root pipe flow fields and relevant border condition thereof, thereby can influence the exchange with disinfective action root canal irrigation liquid, distribute, influence the removal of diverse location microorganism.Therefore, root canal irrigation efficient is studied, the geometry of root pipe, the diameter of Syringe needle Irrigator, Syringe needle Irrigator enters the degree of depth of root pipe, the root canal morphology after the preparation, and the speed of root canal irrigation and several key factors such as design of Syringe needle Irrigator are studied root canal irrigation efficient; For choose reasonable root canal irrigation technology is provided fundamental basis and scientific basis, have great importance for the success rate that improves root canal.
Because root canal system is positioned at the tooth body, comprises complicated anatomic forms such as main root pipe, collateral pulp canal, secondary root pipe, the narrow district of root pipe, root pipe communicating branch, tip of a root bifurcated and difference, dentin is a transparent materials simultaneously, and inner flushing process can't direct observation.Mainly be after washing, tooth to be rived at present on the research experiment, under scanning electron microscope, observe, thus the assessment flush efficiency.This method exists certain defective and influence factor: 1. viewing area is very limited, and some specific region can't be observed, and is difficult to hold the developing result in the territory, whole area under control; 2. riving and observing that the root pipe obtains usually behind the tooth is effect behind the flushing certain hour, can't dynamically successive observation developing result, and the dependency relation of research and time; 3. because the root canal anatomy form is different because of tooth, can't continue after tooth is rived to use, be difficult to study of the influence of a certain specific factor root canal irrigation efficient, the geometry of RUGEN pipe, the diameter of Syringe needle Irrigator, Syringe needle Irrigator enter the degree of depth of root pipe, the speed of root canal irrigation and the design of Syringe needle Irrigator; Based on above defective, especially when the different syringe needles of assessment designed the flushing influential effect, studying its flush efficiency was difficulty and insecure.
Therefore, how to overcome above-mentioned Dentinal opaque characteristic, the individuality that varies with each individual that keeps the root pipe simultaneously, adopt constant flushing speed, dynamic observation root canal irrigation process, the geometry of research root pipe, the diameter of Syringe needle Irrigator, Syringe needle Irrigator enters the degree of depth of root pipe, and the speed of root canal irrigation and the correlative factors such as design of Syringe needle Irrigator are to the influence of root canal irrigation efficient.At this problem, do not see that special device and solution are arranged both at home and abroad at present.
Summary of the invention
