Dentistry And The Law: Dealing With Patients Who Have Been Using Marijuana, Dan Schulte Jd

The Journal of the Michigan Dental Association

When dealing with patients who emit a strong marijuana odor, it's crucial to focus on their capacity to provide informed consent and the ability to deliver treatment up to the standard of care. Judging their level of intoxication solely by appearance and smell can be unreliable, so it's best to avoid making such judgments. Instead, inform patients that you may refuse treatment if their odor or other factors hinder your ability to provide care. To prevent last-minute issues, communicate this policy in advance, particularly to patients with a history of marijuana odor. Dismissing such patients from your practice may also …

For impacted tooth cases, CBCT images can provide more detailed information about the location of the impacted tooth and its surrounding periodontal conditions during treatment. This case report described the treatment of a mild skeletal Class III, facial asymmetry teenager with dilacerated impacted maxillary left central incisor. Because of the unpredictable prognosis of dilacerated impacted central incisor, our treatment goal was to forced erupt the deeply horizontal impacted …

Correction Of Extruded Upper First Molars And Bimaxillary Protrusion By Temporary Anchorage Device, Ignatia Wulandari, Retno Widayati

Taiwanese Journal of Orthodontics

Early loss of the lower first molar may cause extrusion of the upper first molar and mesial tipping of the lower second molar. It could be locked by the mesial contour of the upper second molar, causing the door-wedge effect which impedes the intrusion of the upper first molar. Skeletal Class II malocclusion, canting, and the need for anterior retraction on the upper arch was adding space requirement and anchorage problem to the case. Treatment by using absolute anchorage would be the most efficient way to treat this case. This case report aims to show how to manage molar extrusion, …

Mandibular Expansion Appliances And Their Activation Protocols, Tivanani Venkata Durga Mahendra, Vyshnavi Mulakala, Manda Anoosha

Taiwanese Journal of Orthodontics

A tooth size-arch length discrepancy (TSALD) occurs when there is an imbalance between the size of the teeth and the space available in the dental arches to accommodate them. Relief of crowding through expanding the arch is the most employed non-extraction method in orthodontics. Because of the absence of a midline suture and the resistance of the mandibular body, resolving crowding in the lower arch is more complex than in the upper arch. However, numerous researchers have devised innovative techniques and methods to successfully bring about the desired and stable changes through mandibular expansion. The advantage of this procedure was …
