Device for galvanotherapy in the treatment of multirooted teeth
The invention relates to medicine, namely to dentistry. The device is intended for the treatment of complicated caries multirooted teeth for the introduction of drugs into the area endodontal and periodontal disease through a system of root canals of the tooth and create in these zones depot of drug substances through the implementation of galvanotherapy hydroxide copper-calcium. The device consists of unequally and internal parts made of different metals, representing a galvanic couple. Wakamarina part is a head of cylindrical shape, the side surfaces of which are cut in the form of parallel platforms for better hold with tweezers. Internal part consists of 2-5 pins conical shape. The device allows for long galvanises medicinal substance in all root canals and has good fixation in the cavity of the tooth. 1 Il.
The invention relates to medicine, more specifically to dentistry.
In the treatment of complicated caries for the introduction of drugs into the area endodontal and periodontal disease through the root system to the - depothresis copper-calcium (MMC).
Application depoforeze MMC shown in many complex clinical cases and allows you to save a previously hopeless teeth (Nadesico Century B., Vitkova K. C. Application depoforeze hydroxide copper-calcium in dentistry. Clinical dentistry. - 2001, No. 10, S. 27-30). These indications are endodontic treatment of teeth with impenetrable root canals, with fragments of tools in the channels, after ineffective treatment impregnation methods, it is difficult to conservative treatment of destructive forms of apical periodontitis and other Effectiveness of treatment in these cases is 93-98%, while other known methods only 30-40%. The reason for the high efficiency of the method is the use of science-based tactics dosed introduction into the root system of the tooth metastabilities system three ions in the slurry MMC: hydroxocuprate, ion colloidal hydroxide of copper and the hydroxyl ion.
For a basic method depoforeze MMC (analog) use of special devices for depoforeze “Original II”, “Comfort” (Germany) or their national equivalent “EndoEST”. The cost of these devices is 450-1500 USD. To the device attached Actinidia part of the root canal of the tooth, there is placed the active needle electrode. The passive electrode is fixed extraoral (on the skin of the forearm, the lobe of the ear, skin, cheeks, or lips). For depoforeze use continuous or pulsed current of 0.2 to 2 mA. The amount of electricity that must be obtained by each root canal, is about 5 mA/min of treatment is 3 to 5 treatments with an interval of 7-10 days.
The disadvantages of analog (basic method for the depoforeze MMC) are:
the need for multiple visits to the patients of the medical institution (at least 3 times);
a significant amount of time spent by the dentist for the procedure depoforeze, especially in multi-rooted teeth (1 channel - 5-10 min, 2 channel - 10-20 min, 3 channel - 15-30 minutes);
the need to have expensive equipment (instruments "Comfort", "Original", "EndoEST");
frequent pain during the session, depoforeze because a sufficiently large current is passed through the tooth and the surrounding tissue (1-2 mA);
the impossibility of carrying out depoforeze in teeth with partially preserved alive pulp or the need for in this case, pain.
To reduce the number of visits to medical institutions polzovania expensive device for depoforeze. This pin consists of the ear (in the form of needle length 10 mm) and unequally (in the form of a ball with a diameter of 3 mm) pieces. Feature galvanic pin is that it is made of two different metals that make up a galvanic couple (for example, copper - zinc or silver - zinc). This pin allows to obtain a constant electric potential (galvanic current) inside the root canal of the tooth size of 0.6 C. current is about 0.1 mA (Knappwost A. Neue Entwicklungen zur Depot-ionophorese von Kurpferverbingen, Dtsch Zahnorztl. Z. 1977, №32, 463-465).
For depoforeze MMC walkable part of the root canal of the tooth is filled with a suspension of MMC and injected into him galvanic pin to a depth of not more than 2/3 the length of the channel. Carious tooth cavity is left open to provide the fluid from the root canal or close leaking with a temporary filling. The pin (or pins) are left in the root canal (or channels) of the tooth 15-30 days depending on the form of the disease. The presence of channel a constant electric current of small magnitude and low voltage allows the “slow” electrophoresis MMC without visits to the dentist.
The disadvantage of the prototype is that in the treatment of multirooted C is about 2-3 months or simultaneously accommodate several (2 to 5) plated pins (one in each channel). The latter is rarely possible due to the lack of sufficient space for heads of multiple pins in a single cavity-access in the tooth. You are very close to the location of the mouths of the root canals to each other (mesial canals of lower molars, the buccal canals of the upper molars) simultaneous use of multiple pins is not possible. The simultaneous deployment of multiple pins in the tooth often (especially in the premolar) requires additional expansion cavity access, which leads to a decrease in the resistance of the hard tissues and the subsequent destruction of the tooth crown under the influence of the masticatory load. Another disadvantage of the prototype is its poor fixation in the root canal, which may lead to its loss. Caught in the oral cavity the pin can be aspirated or swallowed patients that can lead to complications with life-threatening.
To eliminate these drawbacks and analog prototype, the authors propose a device for galvanotherapy in the treatment of multirooted teeth (device) consisting of foliar (unequally) and root (internal) parts (drawing). Intra - and foliar (uncinula) of the device are made of different metals that make up gettabset a head of cylindrical shape (diameter 3 mm, height 3 mm), the side surfaces of which are cut and are parallel platform width of 0.7 mm for the best deduction or rotation of the device with dental forceps. Root (ear) part (2) consists of several pins number from 2 to 5 conical shape with a tip diameter of 0.2 mm and a taper of 0.06 mm/mm, depending on the number of root canals in the tooth undergoing treatment. The length of the pins is 10 mm, which corresponds to 2/3 of the average length of channels of a multi-rooted teeth. The length of the pins can be reduced, cutting with scissors, depending on the specific clinical situation (degree of permeability of root canals and their length). As root (ear) part of the device is easily bent (soft metal), it can be given a shape corresponding to the curvature of root canals and the corner of their differences.
The advantages of the proposed device:
the ability to simultaneously treat several root canals multirooted teeth, as the device has several pins that are entered in root channels and only one top part, which reduces 2-4 times the time of treatment and does not require additional extensions Polo the tooth under the influence of masticatory load;
the best retention of the device in the cavity of access due to the fixing root part in different channels of a tooth coming at a different angle to the top portion and having different bending. This drastically lowers the risk of loss, aspiration or swallowing of the device;
the versatility of the device due to the easy adaptation of the root portion of the root canals. It can be used in any of the teeth with the number of root canals from 1 to 5, characterized by the curvature and length of the channels, at the corner location of the channels in the tooth, that is, all the teeth of the person;
efficiency due to the use of only one device for the treatment of one tooth, not 2-5 plated pins, as in the case of use of the prototype.
