Chen Qiao quickly got the answer.

Her eyes lit up, she took out the hospital phone book and dialed Wang Ping's phone number.

"Director Wang, I am Teacher Xu Qiu's intern!"

Wang Ping was shocked and suspicious.

He had an impression of Chen Qiao. He was beautiful and memorized fluently in medical records, but he still followed Xu Qiu.

"What's the matter?" He took a sip of tea without a word of nonsense.

Chen Qiao said politely: "Director Wang, Teacher Xu said he wanted to go to the dentistry department for a root canal treatment..."

"puff!"

Wang Ping sprayed a mouthful of tea, coughed several times before half-joking: "I used to be a tool guy, but now I have asked the tool guy to call me?"

Chen Qiao quickly said, "No, Teacher Xu wants to come to you in person, but there were several more patients at that time..."

"Okay, okay, I don't know him yet. This kid has never come to see me in person."

Wang Ping smiled and cursed a few times, then said, "I will call there, you can just prepare for the operation."

Chen Qiao said happily: "Okay, thank you Director Wang!"

Shortly after hanging up the phone, the stomatologist who had previously contacted him dialed back.

He no longer had the impatience he had before, but instead said softly: "Student Chen, let's connect with the patient's medical records, is it okay?"

Chen Qiao thought, "The teacher's name is really useful", and did not make things difficult for the other party, so she discussed the arrangements for the operating room with the docking doctor.

...

There are five steps in the so-called root canal treatment.

That is, marrow opening, marrow extraction, root canal cleaning, root canal preparation and filling.

Think of teeth as a chili.

This surgery is:

Pull out the chili handle;

Clean out all kinds of messy things such as seeds, cores, and other things in the peppers;

Shape the peppers and build the edges and corners;

Finally, stuff meat inside.

Then fry hot oil until the chili is frying tiger skin, and the aroma is everywhere...

"Teacher, the patient and his family are here, don't be dazed!" Chen Qiao stretched out her white finger and shook her in front of Xu Qiu.

She looked at Xu Qiu suspiciously.

I always feel like the teacher swallowed his saliva. Are you hungry?

Bang-

At this time, Huang Hui brought her best friend in.

This is a very small operation, and it is best if someone is accompanying you.

After the two of them sat down, Xu Qiu talked to the other party about precautions, as well as surgical complications, risks, etc.

"In addition, the methods of root canal treatment are also different, and there are also differences in device selection."

On the equipment, there are hand-purpose stainless steel equipment, such as smooth medullary needles, pulp extraction needles, reaming drills and root canal files.

There is also a hand-used nickel-titanium root canal file.

For machines, there are gg drills, p-type drills, nickel-titanium-type equipment, etc.

However, the most commonly used clinically are h files and k files.

This is a stainless steel material, with poor flexibility and high requirements for the operator.

Accurate feel, fine control of rotation amplitude and lifting force—

If anything is missing, it is easy to destroy the root canal form.

If it is a little tilted, it will cause distortion and deformation.

The nickel alloy material used in cameras is replaced by hand stainless steel, which is more promising.

However, after the analysis of its therapeutic effect using image quantization software, it was found that there was no statistically significant difference between it and the remaining filler after retreatment of stainless steel.

In short, for ordinary doctors, choose expensive machine-purpose nickel alloys.

A skilled practitioner can use stainless steel to compare with nickel alloys for machine use.

The multi-day sign-in reward allowed Xu Qiu to master surgeries including root canal treatment and minimally invasive teeth repair.

It's not a big problem to win this one.

In addition, he has also obtained a master circumcision.

His skills can even carve a Pikachu.

Unfortunately, there are basically no patients to be circumcised in the emergency department, otherwise at least a few more Xiaozhi will be born in the world.

...

"Have you considered it?" Xu Qiu asked in the conference room.

Huang Hui couldn't understand these professional terms at all.

She looked at Xu Qiu with trust and said, "Doctor, what do you think I should do? I will listen to you!"

Xu Qiu gave a suggestion: "H file root canal to treat minimally invasive repair of teeth."

Huang Hui's eyes lit up and she said admiringly: "Doctor, can you still do minimally invasive repair?"

"I will deal with the teeth wear, deformation, or cracks, or tooth decay."

Huang Hui nodded wildly: "Yeah, that's it, that's it!"

My best friend looked at Xu Qiu, still having doubts in her heart.

Such a handsome young doctor is really not the devil of any female director’s private brother?

...

During the whole afternoon, Huang Hui was undergoing various preoperative examinations.

Basic blood routines, etc.

Other examinations, exploration (), percussion (±), loose (-), and no swelling or fistula was seen in the buccal alveolar mucosa.

There are also targeted cone beam ct.

This thing is to further understand the morphology and lesion of the teeth, confirm the adjacent anatomical relationship, and thus define the scope of the surgery.

After all, the posterior teeth are adjacent to important anatomical structures such as the maxillary sinus, mental foramen, and mandibular neural tube.

Moreover, there are 18% of patients with the mental foramen located above the apical foramen. This special case requires at least 2mm of bone to ensure safely performing apical surgery with a diameter of 4mm in the vertical distance of the surgical path.

These experiences and rules are based on many lives.

At five o'clock in the afternoon, Xu Qiu rushed to the dentistry department.

Dr. Huang, who was connected to the department at that time, was a attending physician and also participated in the operation as a representative.

In the operating room.

"Such coincidence, my surname is Huang." Huang Hui laughed foolishly.

Dr. Huang ignored her and turned to Xu Qiu.

The first impression is so handsome.

The second impression is that the side face is so handsome.

"The surgery begins."

Xu Qiu ignored Dr. Huang.

Regular disinfection...

4% Atecaine hydrochloride epinephrine injection, 1.8ml, local infiltration anesthesia...

The angular flap is opened, and the depth reaches the bone surface, and it avoids the lip lace...

Periosteum stripper separation mucosal periosteum film...

The alveolar bone plates in the apical area of ​​the flap exposed and damaged...

Xu Qiu's speed is getting faster and faster, and his feel is getting better and better.

Dr. Huang's expression gradually became solemn when he was puzzled at the beginning until he became excited.

"Wow, this is amazing!"

"Can the 10# stainless steel k file be used like this? The three canals near the cheek, far cheek and palate root are cleared in an instant, without any residue!"

"The root tip is positioned accurately!"

Lying on the hospital bed, Huang Hui opened her mouth wide, and there was a sizzling sound inside her mouth.
Chapter completed!
