Doctor: It's reasonable to perform surgery on yourself.

Chen Qiao soon had the answer.

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

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

Wang Ping was surprised.

He had an impression of Chen Qiao. He was beautiful and could memorize medical records fluently, and he still hung out with Xu Qiu.

"What's the matter?" He took a sip of tea and said nothing nonsense.

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

"puff!"

Wang Ping took a sip of tea, coughed several times, and then said half-jokingly: "I used to be treated as a tool, but now I have a tool call me?"

Chen Qiao quickly said: "No, Teacher Xu wanted to find you in person, but there were several patients at that time..."

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

Wang Ping smiled, cursed a few times, and then said, "I'll call them over there, and you just need to prepare for the surgery."

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

Shortly after hanging up the phone, the dentist I contacted called back.

He no longer had the impatience he had before, and instead whispered softly: "Classmate Chen, let's check the patient's medical records, okay?"

Chen Qiao thought to herself, "Teacher's name is really useful." She did not embarrass the other party and discussed the arrangements for the operating room with the doctor.

…

There are five steps in root canal treatment.

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

Think of your tooth as a chili pepper.

This surgery is:

Remove the pepper handles;

Clean out the seeds, cores and other messy things inside the peppers;

Shape the peppers and trim the edges and corners;

Finally, stuff the meat inside.

Then fry in hot oil until tiger skin is fried on the surface of the pepper and the aroma is overflowing...

"Teacher, the patient and family members are here, stop being dazed!" Chen Qiao stretched out her jade-white finger and waved it in front of Xu Qiu.

She looked at Xu Qiu suspiciously.

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

Clang——

At this time, Huang Hui came in with her best friend.

This is not a big or small operation, so it is best to have someone accompany you.

After the two of them sat down, Xu Qiu told the other party the precautions, complications, risks, etc. of the surgery.

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

On the equipment, there are stainless steel instruments for hand use, such as smooth pulp needles, pulp extraction needles, reamers and root canal files.

There are also hand-operated nickel-titanium root canal files.

For machine use, there are GG drills and P-type drills. Machine-use nickel-titanium instruments, etc.

However, H files and K files are most commonly used clinically.

This is a stainless steel material with poor flexibility, which places high demands on the surgeon.

Precise feel, fine control of rotation range and pulling force——

Lack of any one of them can easily damage the root canal shape.

If it is a little crooked, it will cause distortion.

Nickel alloy materials for machines are a superior alternative to stainless steel for hand use and are more promising.

However, after analyzing its treatment effect using image quantification software, it was found that there was no statistically significant difference between it and hand-used stainless steel for the remaining filling after re-treatment——

In short, for the average doctor, choose the expensive machine-grade nickel alloy.

A skilled artist can use stainless steel by hand as well as nickel alloy by machine.

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

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

Additionally, he holds a master degree in circumcision.

With his skills, he can even carve a Pikachu.

It's a pity that there are basically no patients who want to be circumcised in the emergency department. Otherwise, at least a few Xiaozhi would 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 trusting eyes and said, "Doctor, what do you think I should do, I will listen to you!"

Xu Qiu gave a suggestion: "H file root canal treatment + minimally invasive tooth restoration."

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

"If the teeth are worn, deformed, cracked or decayed, I will take care of them together."

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

The best friend looked at Xu Qiu, still suspicious in her heart.

Is such a handsome young doctor really not the secret younger brother of the female director?

…

Throughout the afternoon, Huang Hui was doing various pre-operative examinations.

Basic blood routine, etc.

Other examinations included probing (+++), percussion (±), loosening (-), and no swelling or fistulas were found in the buccal alveolar mucosa.

There is also targeted cone beam CT.

This thing is to further understand the shape of the teeth and the location of the disease, confirm the adjacent anatomical relationship, and thus delineate the scope of the surgery.

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

Moreover, in 18% of patients, the mental foramen is located above the apical foramen. In this special case, at least 2mm of bone must be ensured in the vertical distance of the surgical path to safely perform apical surgery with a fenestration diameter of 4mm.

These experiences and rules are based on many human lives.

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

The doctor who was in contact at that time, Dr. Huang, was the attending physician and also participated in the operation as a representative.

In the operating room.

"What a coincidence, my last name is also Huang." Huang Hui laughed foolishly.

Dr. Huang ignored her and turned to look at Xu Qiu.

First impression, he is so handsome.

Second impression, his profile is so handsome.

"Let's start the operation."

Xu Qiu ignored Dr. Huang.

Routine disinfection...

4% articaine hydrochloride adrenaline injection, 1.8ml, local infiltration anesthesia...

Open an angle flap, the depth just reaches the bone surface, while avoiding the lip frenulum...

The periosteal stripper separates the mucoperiosteal sheet...

The flap is turned to expose the damaged alveolar bone plate in the apical area...

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

Dr. Huang's expression, from the initial puzzlement, gradually becomes solemn, until he becomes excited.

"Wow, this is great!"

"10 # stainless steel K file can be used like this? The three root canals of the mesiocheir, distocheir and palatine roots were cleared at once, without any residue!"

"The apex positioning is so accurate!"

Lying on the bed, Huang Hui opened her mouth wide, and there was a sizzling sound in her mouth.

At this moment, her eyes were suddenly filled with fear.
