Omicron

 Omicron (B.1.1.529): SARS-CoV-2 Variant

The B.1.1.529 variant was first reported to WHO from South Africa on 24 November 2021.

SYMPTOMS

The new omicron variant of the coronavirus results in mild disease, without prominent syndromes. 

There transmission rate is high.

The most predominant clinical complaint is severe fatigue for one or two days. With them, the headache and the body aches and pain.

Scratchy throat

Those infected do not suffer loss of taste or smell. 

They might have a slight dry cough. Only a few had a slightly high temperature.

There are no prominent symptoms.

There has been no major drop in oxygen levels with the new variant.

The variant is affecting people who are 40 or younger.

According to WHO, It is not yet clear whether infection with Omicron causes more severe disease compared to infections with other variants, including Delta.

Dry Socket

 Dry Socket or Alveolar Osteitis is a painful condition that can arise after a permanent adult tooth extraction. 

It happens when a blood clot does not form in the cavity to protect the exposed tissues.

It usually happens 3–5 days after surgery. A dry socket is a condition in which there is inflammation of the jawbone (or alveolar bone) after tooth extraction.

About 2% to 5% of people — develop dry sockets after a wisdom tooth extraction. 

After a tooth extraction, you're at risk of developing dry socket. 

This risk is present until you're fully healed, which may take 7 to 10 days in many cases.

Causes

The precise cause of dry socket remains the subject of study. 

Researchers suspect that certain issues may be involved, such as:

• Bacterial contamination of the socket
• Trauma at the surgical site from a difficult extraction, as with an impacted wisdom tooth

Risk factors

Smoking and tobacco use

 Sucking through a straw, or forceful spitting after extraction

Oral contraceptives

Improper at-home care

Having dry socket in the past

Tooth or gum infection

Symptoms

Signs and symptoms of dry socket may include:

• Severe pain within a few days after a tooth extraction
• Partial or total loss of the blood clot at the tooth extraction site, which you may notice as an empty-looking (dry) socket
• Visible bone in the socket
• Pain that radiates from the socket to your ear, eye, temple or neck on the same side of your face as the extraction
• Bad breath or a foul odor coming from your mouth
• Unpleasant taste in your mouth
• So it's important to seek dental care. If left untreated, this can lead to infection and other complications.
• Dry socket is treated by your dentist by flushing it thoroughly with saline, and then packing it with medicated paste or dressing.

 Dry socket, or alveolar osteitis, can last for up to 7 days or even more.

Light Curing

  

 Light Curing

Light Curing is the energy to fully polymerize the light cure based dental material.

It can be used on several different dental materials that are curable by light.

 The light used falls under the visible blue light spectrum. 

This light is delivered over a range of wavelengths and varies for each type of device. 

There are four basic types of dental curing light sources: tungsten halogen, light-emitting diodes, plasma arcs, and lasers. 

The two most common are halogen and LEDs.

There are two types of LED curing lights: those that contain blue-only LEDs and poly-LED curing lights .

Most manufacturers have stopped making Halogen curing lights, partly because LED lights are more efficient than halogen light sources, but also because the incandescent bulbs of it will soon become scarce. 

How much light produced?

Halogen light deliver a broad spectrum of light of 400 mW/cm2 during 40 seconds of curing.

LED curing lights that contain blue-only LEDs and provide blue light within a narrow spectral range of 440 nm to 490 nm, and poly-LED curing lights that deliver a broader spectrum of light in the range of 390 nm to 490 nm.

Resin composite’s instructions for use states that the curing light’s minimum irradiance output should be at least 300 mW/cm2 to 400 mW/cm2.

 Currently, most QTH curing lights deliver at least 600 mW/cm2, and some lights that use specialized turbo tips can deliver more than 1,300 mW/cm2.

The latest generation of LED curing lights can deliver an irradiance output greater than 2,000 mW/cm2, and some poly-LED curing light devices include supplemental LEDs that emit light at additional wavelengths

 Depending on the shade and brand of composite resin, the minimum energy requirements to photopolymerize resins range from 6 J/cm2 to 24 J/cm2 for a 2-mm increment of composite.

So in 20 seconds 16 J/cm2 is delivered to polymerize the material used.

Not all lights are the same. They do not deliver the same amount of light.

eg;- Valo, Demi, Radical

COLLIMATION

Light must be focused.

Lense to focus light. It  can be of acrylic or optic fiber.

Light as Wave ( Colours )

The need for different wavelenght is a hidden reality.

whichever colour is being emitted ,it should be homogeneous.

Tips for Using a Curing Light

Before use, inspect the light guide tip and remove any contaminants on the surface. 

 The light tip should be at right angles to the tooth surface being restored .

Stabilize the light when curing; use a finger rest.

Begin curing 1 mm away from tooth; after 1 second bring the tip as close to the tooth as possible.

Increase the light exposure time for preparations more than 2 mm to 3 mm deep .

Air-cool the tooth and the restoration during each light-curing cycle.

Artificial Intelligence In Dentistry

 Artificial Intelligence In Dentistry

AI can improve quality in the dental field using image detection, classification, and segmentation.

AI is when computers and other machines mimic human cognition, and are capable of learning, thinking, and making decisions or taking actions.

This software uses a cloud-based algorithm.

AI works by combining large amounts of data with fast, iterative processing and intelligent algorithms, allowing the software to learn automatically from patterns or features in the data.

In the beginning we used paper works then changed it to digital and the future is AI.

Paper →→Digital ⟶⟶ AI

In AI ,data is processed to make models.

This data processing  mainly consists of two steps.

1. Computer Vision 

2. Pattern Recognition

Computer vision is mainly based on image recognition.

Pattern Recognition -  Profile

                                   History

                                   Symptoms 

These 3 are needed in pattern recognition.

Uses of AI

Can detect any pattern and images

• Diagnosis
• Jaw bone growth pattern prediction
• ortho treatments
• decision for extraction
• detection of caries
• vertical fracture analysis
• Morphology of roots
• In endodontic treatments

 There are also other areas in which AI can be widely used.

Limitations of AI 

1. AI focuses only  limited areas.

2. It cannot understand meaning. So No emotions like humans.

future is AI
