While no clear statistical association was found for gene variations in IL1A, a sound association was found in the comparative analysis of subjects homozygous [2/2(TT)] for the IL1B gene, which resulted in a 2 times increased risk of suffering post-orthodontic EARR in root-filled teeth [OR: 2.032 (p=0.031); CI:1.99-14.77] when compared with their controls with vital [...]

The following case is an example of the successful root canal treatment of a cracked tooth. Tooth #19 was diagnosed as necrotic pulp with acute apical abscess. RCT was recommended to save the tooth. There was a large 10mm buccal probing depth, however, since the tooth was diagnosed as necrotic, this deep pocket is assumed [...]

The teeth though look quite strong from the outside, but in the real, they have softer nerve chambers. They include the blood vessels and nerve tissues. The deep injuries can cause the destruction of the nerves. If they utterly destroy, they will affect the chamber, causing certain infections. In case of such condition, a patient [...]

While 63% of Americans would like to avoid getting a root canal, 69% want to avoid losing a permanent tooth, according to a survey conducted by the American Association of Endodontists (AAE). The January survey of 1,014 U.S. adults found that Americans want to avoid losing a permanent tooth more than getting the flu, paying [...]

Stan, a recent reader of the blog, commented, “I’m 66 and have an abscessed pre-molar that had rct and a cap 25 years ago. Went to my dentist (who does implants) and was told rct retreatment had a 50% failure rate and the implant-cap was my best option. I had agreed and he injected anesthetic. [...]

Cells exposed to MTA revealed a cytocompatibility pattern similar to the untreated cells (negative control), at both experimental times (P > 0.05). iRoot, however, promoted a significantly poorer viability than MTA and the control, after 48 h of exposure (P < 0.001). Nevertheless, iRoot did not induce critical cytotoxic effects because cell viability remained higher [...]

Mesiobuccal resection surgery was performed concomitant with GTR therapy to manage endodontic–periodontal combined lesions on teeth 17 and 26. The increased mobility after the periodontal surgery gradually decreased during the healing period. At 15 and 20 month follow-ups, respectively, the teeth showed no mobility, 2–3 mm pocket depths and no further bone loss.

We have had lots of discussion regarding the use of CBCT in endodontic diagnosis and treatment planning. CBCT is the future of endodontics. 3D imaging as an adjunct to 2D imaging is superior to 2D imaging alone. The ability to evaluate a tooth in a sagittal and axial plane (in additional to the traditional coronal [...]

This 13 yr old young lady had some trauma to #8 during a softball game. As you can imagine, the discoloration is of significant concern to the patient. At the time of the exam, tooth #8 is non-responsive to thermal testing, normal to probing and mildly percussion sensitive. DX: Necrotic w/ SAP. RCT recommended with [...]

According to a news release from the Massachusetts Attorney General’s office, a former Massachusetts dentist who pleaded guilty last week to charges of Medicaid fraud for using paper clips in place of stainless steel posts during patients’ root canals was sentenced to jail Monday.
