Wow, I can't believe I forgot to post again! darn...Anyways, the thing that I thought was most important about the lecture was the statement that stainless steel crowns can have a 100% success rate if done correctly....

The moment you work on a tooth you are causing pulpal pathology. Even the smallest occlusal restorations have an effect on the pulp. Also, even though a electric pulp testing can be convenient, it really isn't reliable enough for clinical Dx.

I thought the most informative statement was about the rule of three's, 3 years for calcication, 3 years for eruption, 3 years after eruption for apical closure.

EPT is useless for primary tooth dx. Also, do not use CO2 on primary teeth for cold testing because it can cause craze lines, use endo ice.

As a dentist, it's important to identify the state of inflammation of the pulp in order to determine if the tooth is vital or nonvital.

The electric pulp test is not very useful for deciduous teeth. Do not directly ask patients if they feel pain, they will react when they really do.

When taking history of chief complaint, remember that 18% of normal, atrophic pulps also report pain. Also, endo-ice is best for pulp testing primary teeth.

For pulp therapy in teeth with deep caries,leave behind some softened dentin to form a dentin cap (hopefully).

Dental pulp is affected by ANY cavity preparation, however major or minor. Also, the best material to cap pulp is dentin, even if it is softened, affected dentin.

The best pulp test for primary teeth is ice or endo ice. Also, the pulps of diciduous teeth are large in relation to crown size, and the pulp horns found directly under the cusp tips.

In deciduous teeth, pulpotomy is the teatment of choice (No pulp capping). Whilst in permanent teeth with open apices, pulp capping is preferable.

During the pulp test do not ask the kid to tell you when it hurts because they will react immediately to the stimulus, just tell them to tell you when it feels ice like ice cream. Also EPT is useless in decidious teeth and inmature permanent teeth.

Indications for pulp capping include 1mm or smaller exposure, clean field, no history of spontaneous pain, and open apices or young permanent tooth. Pulpotomy is the treatment of choice for deciduous teeth.

I learned that it is important to sterilize all of your cavity preps because bacteria causes the pulpal insult. Also, we need to recognize the state of survival that the pulp is in in order to treat it correctly and to avoid damaging it further.

Prepping a tooth can cause damage to the pulp and this can be seen by cutting a tooth in the dark. The bur will turn red hot and sparks will fly! Also learned the concept that you should sterilize every cavity prep before restoring.

Although no difference between hot and cold test, use endo-ice or ice and ask when it feels like biting an ice-cream and EPT aint helpful; Increase 10 degreeC, 50% of pulp will die.

Be prepared for pulp therapy when treating caries. Affected dentin is OK to leave when caries is deep near the pulp. GI base is not necessary for composite restorations and thermally isolates amalgam restorations.

when doing pulp testing, always tell a child something like, "tell me when u feel something cold like ice cream," NOT, "tell me when this hurts," because the result will be inconclusive. Also, there is no difference between cold and hot sensation, so a cold test using endo ice is sufficient.

Drilling on a tooth causes damage to the pulp. Therefore, the less drilling one is able to do the better for the long-term survival of the tooth.

Pulpal harm (reversible or irreversible pulpitis) may occur when preparing a large carious lesion but to the lack of irrigation. There is also no difference in pulpal response from heat or cold, but heat test present a negative psychological response.

A few neat things that I learned in class:
In primary teeth, radiolucencies are usually located in furcations (not around root apices as with permanent teeth). Therefore, bitewings will be more useful than PA radiographs in determinig the extent of the child's radiolucency.
I also learned that Dr. Duperon has taught many of our faculty including Dr. White.

When pulp exposure occurs while removing caries on a deciduous tooth, irreversible pulpitis is assumed and polpotomy is the treatment of choice. However, when working on a young permanent tooth with open apices pulp capping may be our best treatment option.

It was interesting to find out that EPT shouldn't be used on pediatric patients. Rather endo ice or even ice itself should be used. And when working with a child, one shouldn't ask them "tell me when this hurts" - but rather ask them "tell me when this feels like really cold ice cream." Asking about pain may lead the child to expect pain and give you a false reading - or they may just respond to any sort of stimulus.

CO2 is contraindicated for children during pulp testing because it will cause craze lines on teeth. When endo ice isn't available, keeping some old amalgam capsules filled with water in the freezer can come in handy. When drilling, every time you cut a dentinal tubule, you damage an odontoblast.
Sujain Dissanayake #119

The most magical of all minutes:
I thought the most important thing that I learned was that a cold test is better than a hot test for kids because you can just tell them to let you know when there tooth "feels cold" like when they eat ice cream. This is much better than telling him/her that you are going to stick a hot instrument in their mouth and to tell you when it feels hot like a fire.
Paul Field #127

Even with minimal invasive technique, caries removal and restorative preps can cause a reactive and reversible pulpitis. Excavation to get every last bit of affected and infected caries could compromise the long term health of the tooth. Therefore in these cases, it is better to leave a thin, affected wall of dentin subject to a minimal irritation to serve as a pulp cap. This rather than pursuing the thinnest possible wall coinciding with a more severe irritation that could irreversibly damage the long-term prognosis and health of the tooth.

One new idea that stuck out is the suggestion to clean out each cavity prep with bleach. I also found the whole pulp testing issue of primary teeth interesting...that CO2 can cause crazing in primary teeth. Better to use Endo Ice...just keep it on hand so you don't have to mess with ice in carpules, etc.

The most useful information I took away from the lecture was the rule of 3's: 3 yrs for teeth to finish calcifying, 3 yrs then to erupt, 3 yrs then to finish developing the roots. Also, I had not realized how much heat is generated by cutting enamel with a bur (though the burned teeth in my typodont should have given me a clue!)

Any drilling, even if it is minimal, can potentially affect the pulp. Pulpal diagnosis is not very clear cut, and definitive diagnosis can only truly be done histologically. Also, if you drill on a tooth in the dark, the cutting portion of the bur will be red hot.

EPTs are not reliable on deciduous teeth because research has shown that a significant amount of teeth do not respond to an EPT in an expected manner. Surprisingly, 20% of vital teeth do not respond to electric pulp testing and as a result, unnecessary pulp therapy could be performed on an otherwise healthy tooth.

Richard Duong #124

Following caries removal and prior to placing a comp or Ag restoration material, it is important to sterilize the cavity w/NaOCl to improve the success of the treatment. The restorations on deep carious lesions of permanent teeth should be re-entered in 6-12 months to remove remaining caries and restore, however this is not done on decidious teeth.
