Endodontic Access Through Zirconia Crowns: A Comparative Evaluation Of 3d Guided Versus Free-Handed Techniques, Maryam Alrughaib

Theses and Dissertations

Objective:

Accessing canals through full-coverage zirconia crowns is challenging and may increase the risk of misdirection, excessive dentin removal, and prolonged chair time. Guided endodontic access has been proposed to improve efficiency and precision. This study compared the accuracy and time efficiency of guided versus free-hand endodontic access through zirconia restorations. The hypothesis was that guided access would enhance canal localization precision and significantly reduce access time.

Methods:

Thirty-two extracted maxillary premolars were restored with 1-mm–reduced monolithic zirconia crowns (3Y-TZP, Katana HTML, Kuraray, Japan) and mounted in Modupro models. Teeth were assigned to two groups (n = 16 each): guided …

Molar-Incisor Hypomineralization: Diagnosis, Management, And Treatment, Giovana Anovazzi Medeiros Dds, Msc, Phd, Bahareh Enghiad Dmd, James R. Boynton Dds, Ms

The Journal of the Michigan Dental Association

Molar Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect affecting at least one permanent first molar. Characterized by high porosity and reduced mineral content, MIH leads to hypersensitivity, post-eruptive breakdown, and increased caries susceptibility. The etiology is multifactorial, typically occurring between birth and four years of age. Management depends on severity, ranging from topical fluorides and sealants for mild cases to stainless-steel crowns or extractions for severe instances. Because porous enamel facilitates bacterial penetration and pulpal inflammation, achieving effective local anesthesia is often difficult, necessitating individualized behavioral management and early intervention to preserve tooth structure.

What About Our Teen-Age Patients?, Michelle C. Dziurgot

The Journal of the Michigan Dental Association

This editorial advocates for "mentally treating" teenage patients, specifically those around 14 years of age, as adults. By respecting their concerns and allowing age-appropriate decisions, clinicians can enhance a teen's dental IQ and self-esteem. This approach fosters confidence, communication, and independence, encouraging patients to take accountability for their treatment outcomes. Respectful dialogue leads to better compliance with home care, such as using rotary brushes or wearing retainers. Ultimately, treating teenagers with empathy and valuing their opinions helps them blossom into responsible adults while building lasting professional bonds.

Evaluation Of Finger-Tightening Torque Applied To Implant Healing Abutments By Dental Providers With Varying Experience And Physical Characteristics: An In-Vitro Study., Bayan Abuhalimeh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Aim: The primary objective of this project is to measure the actual torque applied by dental providers when finger-tightening a healing abutment and assess the variability among individuals. A secondary objective is to analyze the correlation between applied torque and: provider experience level (residents, general dentist, specialist); gender; age; and, physical attributes (e.g., grip strength, hand size, and dominant hand used for tightening). The null hypothesis is that there is no difference in the mean finger-tightening among the three groups of dental providers, and there are no significant differences in torque values among practitioners based on demographic and professional variables. …
