Root And Canal Morphology Of Mandibular Second Molars In An Egyptian Subpopulation: A Cone-Beam Computed Tomography Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Background: This study was using Cone beam computed tomography (CBCT) to examine the anatomical variations in mandibular second molars in an Egyptian sub-population. Methods: A total of 350 CBCT images (215 females and 135 males, aged 15–65 years) of mandibular second molars were evaluated. Samples were evaluated in terms of: number of roots, number of root canals, roots’ cross section as well as prevalence and configurations of C-shaped canals. Statistical analysis was done to highlight differences between different categories and their prevalence among genders (significance level was set at p < 0.05). Data were presented as frequency and percentage values and were analyzed using chi square test followed by pairwise comparisons utilizing multiple Fisher’s exact tests with Bonferroni correction. The significance level was set at p < 0.05 within all tests. Results: Of the 350 mandibular second molars evaluated, 87.2% were non-C-shaped while 12.8% were C-shaped with no gender-based statistically significant differences (χ2 = 0.19, p = 0.656). Most samples had three root canals (80%) followed by two (16%), then one (3.2%), and finally four (0.8%) root canals. Among the non-C-shaped molars, presence of two roots was most common (83.4%) followed by presence of a single root (16.2%), and only one sample (0.2%) had three roots, and this had no correlation with gender (χ2 = 1.86, p = 0.431). In the mesial roots Type IV Vertucci was the most common configuration found (68.8%), while Type I was the most prevalent in the distal roots (91.8%). The long oval configuration was the most commonly found cross section in mesial roots while “oval” was the most prevalent in distal roots. Conclusion: Egyptian sub-population shows highly variable morphological features in mandibular second molars, hence, CBCT is highly recommended on case-to-case conditions.

Strategies To Encourage Recall And Prevent Relapse After Full Mouth Rehabilitation Under General Anesthesia In Children, Claire Koukol

Capstone Experience

Background: Dental caries are preventable. Dentists utilize many prevention strategies in the office and provide at-home education to families. However, once a child develops Early Childhood Caries (ECC), especially in more severe cases, they may need general anesthesia (GA) to complete treatment. While this is an effective way to achieve full mouth dental rehabilitation (FMDR), this burdens the healthcare systems and families and does not come without risk to the patient. Patients with high caries experience remain at high risk of caries relapse after FMDR under GA, sometimes necessitating additional FMDR under GA. While there has been a significant amount …

Dentistry And The Law: Problems With Referral Incentives Explained, Daniel Schulte Jd

The Journal of the Michigan Dental Association

Incorporating referral incentives in dentistry, like gift cards or raffles, can present ethical and legal issues. The MDA's ethical rule 4.E prohibits rebates or fee splitting, extending to any referral source, including patients. Gift cards may be perceived as rebates. Raffle tickets are less problematic, but only the winner gains something of value. State law (MCL 333.16221) deems fee division unethical. For insurance and dental plan agreements, check for clauses mandating specific fee schedules and discouraging referral fees to ensure compliance. Federal laws might also apply if incentives are used for Medicaid or Medicare patients.

Facial Growth: Does It Play A Role In Long-Term Stability Of Orthodontic Treatment?, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Following orthodontic treatment there is usually a period of retention to maintain the treatment result. This period can vary from a few years to even lifelong retention all depending upon the clinician, type of treatment and severity of the initial malocclusion. In most cases retention is planned for one to two years, but some clinicians routinely recommend continuous retention into adulthood. The retention planned for a patient is unfortunately often based on intuition rather than on scientific evidence. Furthermore, the retention is frequently not planned based on the initial malocclusion, the patient's facial growth pattern nor is attention paid to …
