Diagnosis And Treatment Of Swallowing Dysfunctions : Semg Cognitive Training As An Adjunct To Conventional Therapy, Vicky T. Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

This study compared surface electromyography (sEMG) cognitive training to conventional myofunctional therapy in controlling a swallowing dysfunction, commonly referred to as "tongue thrust". Nasal airway resistance (NAR) was assessed on every subject, to rule out mechanical obstruction that would prevent proper function. The scope of this investigation composed of evaluating baseline activity and dry swallowing patterns. Subjects were distributed to one of three treatment groups: sEMG cognitive training, conventional myofunctional therapy, and control, based on the degree of NAR (normal, mild, or moderate). Initial sEMG recordings were then taken on subjects that clinically demonstrated a tongue thrust habit to confirm …

The Impact Of Variations In Buccolingual Thickness Of Maxillary Anterior Dentition On First Order Arch Form Adjustments, Craig A. Andreiko

Loma Linda University Electronic Theses, Dissertations & Projects

Pre-adjusted bracket systems offer the clinician the convenience of working with both fewer in number and smaller magnitude adjustments in the archwire. The purpose of this study was to examine the normal variations in the thickness of the six maxillary anterior teeth and how this relates to anticipated first order bends in the archwire. A second purpose was to examine these same teeth for bilateral symmetry.

Thirty casts from the Loma Linda University completed treatment files were examined with respect to variations in the thicknesses of the crowns at the level of the archwire plane. From these, the mean difference …
