Local anesthetic solution

Root canal therapy is painful but not if the patient was anesthetized very well. Today, we have a revolution in the dental material market. Solutions are always available , but you have to look into it.

Onset from Onpharma is an anesthetic product used in root canal treatments. It works by replacing a small amount of the acidic anesthetic (PH3.5) with sodium bicarbonate (PH8.4) via a mixing pen in a standard lidocain cartridge.

Benefit: This Buffered anesthetic has PH closer to the patient physiological PH allowing for more comfortable injection and shorter latency period for onset of anesthetic.

Endolce: check the sensitivity of the pulp after anesthesia by using ENDOLCE;pulp sensitivity tester.

Discussing Other Dentists' Work with Patients | The Curious Dentist

Teeth whitening

There are 2 methods to choose from

1) In Office: It is a light enhanced technique done in clinic. It saves lots of time for the patient since the result is instant. Excellent option for busy people who want the result same day.

2) At home: The patient put the whitening gel himself at home in a pre- fabricated customized trays.It takes up to 21 days to get the final result.

Before doing any of them ,Dentist must check your teeth to observe any decays,stains and exposed dentin. This determines if there is potential sensitivity,treatment duration and expected result.

The procedure for:
1) In office: A whitening gel is applied to your teeth .Photos  of before situation are taken to compare the effectiveness after the treatment. Gum and lips are protected  and a coat of hydrogen peroxide is applied on teeth for 20 minutes to be removed for another coat since hydrogen peroxide gets deactivated in max 30 mins. Up to 4 coats can be applied depending on each situation.
2) At home: Two whitening trays are delivered to the patient for use at home. A whitening gel is given to be applied home.The whitening gel  can be applied for 30 minutes  every night before bedtime up to 21 days.

Now to get the best result, I use my own protocol in my practice. Most of the time the two techniques are recommended. I always ask the patient to keep the at home trays for later touch ups(maintenance). Touch ups differ from case to case.It could be every 6 months or every one year. It depends on each patient situation and life style.

Disclaimer:This procedure should be done under the observation of a specialist. Don't try to do the above mentioned procedure at home alone. I take no responsibility for any misuse or misunderstanding. Always contact your dentist for any medical use or advise.

what are minimal invasive burs?

To give you a glimpse about minimal invasive burs, I will first explain the concept. Nowadays, tooth preparation techniques are totally different. In the presence of bonding materials,no need anymore to prepare tooth tissue according to Black classification.
Minimal invasive dentistry is gentle and conservative when it comes to removing carious lesions. You only remove soft pigmented dentin that does not sound. In class one,you prep teeth following carious fissures and pits only.You use the smallest bur available that can remove that carious spot and still respect anatomy.In figure 1, you see a set of burs used for minimal invasive preparations in my practice when treating carious lesions.

                                                                   Figure 1


Companies have shifted towards being  conservative by producing a whole line of burs dedicated towards minimal invasive tooth preparation. SHOFU for example included a whole section of minimal invasive burs with clear demonstrative illustrations Figure 2,3,4,5&6

                                                                        Figure 2

                                                                 Figure 3

                                                                         Figure 4

                                                                    Figure 5

                                                                         Figure 6

Finishing or just beveling the prepared sites, you can use a set of fine small finishing burs specifically selected to  just round any sharp edges left after preparation.These same burs can be used for finishing the composite after placement.In Figure 7, 8&9 you can see a set of finishing burs from German company Schezer used in my practice for this purpose.

                                                                              Figure 7

Previously I blogged about oral sedation and talked about some medications. In this blog however, I will talk more about general benefits of oral sedation and its application in dentistry.

If dentist apply oral sedation in his office ,he can:

1. Increase the quality of his procedures
2. Increase the quantity of treatments
3. Have more accepted treatment plans
4. Decrease stress for the patient 

Patients who can benefit from oral sedation are so many however I will mention some of them ;

• Complex big cases patients
• Those who are allergic to Anesthesia
• Phobic,Anxious and Fearful patients
• Sever Gag reflex patients
• Post operative sensitive patients

It is documented that 30 to 50% of patients avoid the dentist due to fear.


Spectrum of sedation has 3 phases

1. Minimal sedation
2. Moderate sedation
3. Deep sedation

Dentists should sedate patients in their office within the minimal and moderate levels only. Deep sedation attempts should be avoided unless the dentist has gone
through special residency training and got special licence.

Let us mention some of the most popular oral sedatives dentists can use:

Generic                       Trade
Diazepam                     Valium
Zalepon                         Sonata
Triazolam                      Halcion
Hydroxyzine                   Atarax or Vistaril
Lorazepam                      Ativan
Nitrous Oxide                 Laughing gas


In every dental office using oral sedatives, Romazicon (flumazenil) 10ml injection 1mg/10ml or 0.1mg/ml should be available to reverse the effect of bezos in case of over sedation(overdose).

Protocols: Usually pill can be taken one to two hours before procedure. If pill will be taken home, somebody should accompany the patient and he should be informed.
A dose at night can be given as well one day before the appointment depending on the case.

Valium(Diazepam) is usually given at bedtime . Dose depends on some factors like age, BMI, history and other medications.

• If age >or = to 65,then the dose ranges from 0 to 2.5mg 
• If BMI >or= to 30,then the dose ranges from 5 to 10mg

The more obese the patient is the higher the dose that can be given

Patients taking CNS depressants or other serious medications should be treated carefully. You should avoid prescribing Valium to all patients with the same dosage. Please seek  consultation from experts before prescribing any medicine
in critical medical cases.

If you use oral sedatives in your office, it is recommended to track and monitor vital sign during the whole treatment appointment.Pulse oximeter blood pressure unite is necessary in this regard.
