JOURNAL FREE ACCESSMost of dentine tubules from the base of so-called cuneiform defect to pulp-chamber showed zonular opaque. By means of iontophoresis, or the conventional dying method of the extracted teeth and by the experiment of vital body, penetration of medicines in this part was observed so less than that in the healthy part.
The deposit of calcium at the dentine tubules in this part is much than that in the healthy dentine.
In the case of the defect in the extracted teeth which was experimentally made by toothpaste, the dentine part showed no difference from the healthy dentine in penetration of X-ray and medicines by means of iontophoresis, or usual dying method.View full abstractDownload PDF (3267K) -

JOURNAL FREE ACCESSMeny methods have been described for the preoperative hand disinfection so far, but recently guaternary ammonium compounds and Hexachlorophene are widely used.
First, the bacteriologial experiments were made on the scrubbing with lysol and the modified technic of Fürbringer's method, which has been being adapted until recently in our clinic.
Next, the comparative experiments were made on various technics of scrubbing with the Hyamine and the G-11 soap containing 2 per cent of Hexachlorophene.View full abstractDownload PDF (1037K) -

JOURNAL FREE ACCESSChlorophyll showed an effective result in case of so-called aphthous stomatitis.
Hypodermic injection of 20 mg was administered a day. As the results obtained eight of fifteen cases could be cured within three days, five cases within five days, and only two cases did not respont to it.View full abstractDownload PDF (2753K) -

JOURNAL FREE ACCESSVarious kinds of experiments by use of spiral instruments were made by Suzuki with more favorable results than by use of other instruments.
Now in this paper 76 clinical cases are presented.
The results obtained by determination of its use by radiograms are as follows:
Favorable in 50 cases (65.7%), excess of filling in 9 cases (11.9%), and insufficient filling in 17 cases (22.4%) .
Thus it could be concluded that most favorable results obtained in case of enlarging the root canal sufficiently.View full abstractDownload PDF (2027K) -

JOURNAL FREE ACCESSIn applying a contra-angle to a dental operation when electro-anesthesia is being used, it has been necessary to devise some electro-conductible lubricant in the contra-angle in order to secure the most effective performance of electro-anesthesia. This is necessary because the conventional machine oil is an insulator of electricity.
This new lubricant had to possess the following characteristics.
1. To be a conductor of electricity.
2. To lessen friction.
3. To prevent rusting of metals.
4. To be harmless to the human body.
5. To possess sterilizing effect.
6. To be stainless to body or instruments.
With these prerequisites in mind, the author devised two kinds of electro-conductible lubricant to be used in the contra-angle. The first has the greater germicidal effect. The composition of each is as follows:
(I)
Cation Detergent
(Positive Soap) 10%
Glycerin 30%
Sodium Nitrite 1%
Water 59%
(II)
Gelatine 1%
Glycerin 30%
Merzonin (0.1%) 10%
Sodium Nitrite 1%
Water 58%View full abstractDownload PDF (2388K) -

JOURNAL FREE ACCESSFacility of the clinical application of iontophoresis depends upon the good holder of the electrode.
In our clinic, however, the Suzuki's electrode is used, so the holding of the electrode is not so easy as that of the needle electrode. Then Prof. Suzuki had devised new holding apparatus for his electrode, intra-oral apparatus based on D. Schacke's clump and extra-oral apparatus utilizing the forehead belt.
The authors improved those two kinds of holding apparatus. This apparatus consisted of a forehead belt and a lead arm connected the forehead belt through an articulation at the one extremity and the holder of electrode by a screw at another extremity. A thin plate was put between the holder and the screw. At one side of the holder was the small hole made to insert the electrode, and beside the hole, a catch of 18-8 steel wire was attached.
By using this holding apparatus, the application of iontophcresis at root canal treatment has become easier and simple.View full abstractDownload PDF (4186K) -

JOURNAL FREE ACCESSIn the field of operative dentistry, it is most important to sterilize completely the instruments, especially the small instruments inserted into the root canals of the teeth.
The authors tried both basic and clinical experiments on sterilization of the broach reamers, using such chemical agents as alcohol solutions, positive soap solutions, lysol solutions and phenol solutions.
1) The reamers must be cleaned with brush and water, before they are sterilized with chemical agents.
2) In order to secure the effect of sterilization, 0.5% positive soap solution and 5% lysol solution need about 10 minutes. These are the shortest ways of the chemical agents used in the experiments.
3) Of the used chemical agents, a positive soap solution has the best germicidal effect.
4) At the clinic, the use of the instrument case which is filled by formaldehyd gas is recommendable, after sterilization by solution of a chemical agent.View full abstractDownload PDF (2546K)
