Forces Generated During Plush Animal Pacifier Use: A Pilot Study.

Purpose: Plush animal pacifiers (detachable weighted stuffed animals) have gained popularity. Although pacifiers have well-known benefits, they can also affect the development of the cranio-facial-respiratory complex. The purpose of this study was to study the forces gener- ated on the maxillary arch region during the use of plush animal pacifiers.

Functional comparison of pacifiers using finite element analysis.

Background: Pacifiers have been shown to affect maxillary growth related to the anatomic structure of the palate and forces placed upon it during sucking. This study compares and evaluates the mechanical behavior of pacifiers of different design and size (i.e.

Computational simulation of pacifier deformation and interaction with the palate.

Objectives: The objective of this study is to demonstrate that computational finite element models can be used to reliably simulate dynamic interaction between a pacifier, the palate, and the tongue during nonnutritive sucking (NNS). The interactions can be quantified by the results of finite element analyses which include deformation, strain, stress, contact force, and contact area.

Materials And Methods: A finite element model was created based upon CAD solid models of an infant pacifier and palate.

Anatomy of a properly taken toothprints thermoplastic bite impression.

The Toothprints thermoplastic bite impression technique, like most procedures in clinical practice, is technique-sensitive. The biometric information available from the thermoplastic wafer is directly proportional to the care with which the technique is performed, as well as the cooperation and understanding of the child. Although the amount of information and the detail we obtain with the impression of only a few teeth (tooth size and occlusal anatomy are able to be digitized to 50 microns), along with saliva for scent dog tracking and cellular DNA analysis, it is a properly taken full-arch bite impression that would provide the best opportunity for infinite concordant matches for identification, should the need arise.

Support for the use of thermoplastic bite impressions to aid in the identification of missing and unknown children.

This paper presents a response to the editorial opinion expressed in the position paper "Promotion of the Use of a Thermoplastic Material to Aid in the Identification of Unidentified Human Remains," published on page 14 of this issue of the JOURNAL OF THE MASSACHUSETTS DENTAL SOCIETY. No references were cited in that paper: Because the mission of the American Board of Forensic Odontology (ABFO) is to "promote and enhance the science of forensic odontology" and realizing that the ABFO Guidelines on bite mark evidence has failed law enforcement in several high-profile cases in the past, it is necessary to publish a referenced response addressing some of the statements that were made in the ABFO article.
