Using Dental Stem Cells To Regenerate Tooth Tissue And Whole Tooth Replacement, Peretz Rapoport

The Science Journal of the Lander College of Arts and Sciences

Irreversible dental problems such as dental carries and periodontal disease create a plethora of general and oral health issues. Although there are solutions to treat these different problems, an emphasis has been placed on finding a solution to these points with the help of bioengineering and stem cells. Using stem cells to treat these problems could result in a more permanent fix than the methods dentists employ now. Two novel approaches to fixing irreversible dental problems via stem cell therapy are tooth tissue regeneration and whole tooth replacement. This paper reviews the advantages and disadvantages of using dental pulp stem …

The Use Of Oral Appliances For Obstructive Sleep Apnea-Hypopnea Syndrome (Osahs ), You-Ning Gao, Jenny Zwei-Chieng Chang, Ming-Hsien Lan, Wen-Chung Chang, Yuan-Yi Tung

Taiwanese Journal of Orthodontics

The obstructive sleep apnea–hypopnea syndrome (OSAHS) is a common sleep-related breathing disorder characterized by repetitive obstructions of the upper airway during sleep. Nasal continuous positive airway pressure (CPAP) is the primary choice of treatment for OSAHS, but many patients are unable or unwilling to comply with the treatment. The modification of pharyngeal patency by oral appliances (OA) is an alternative treatment for OSAHS. This article provides a brief review and information of the oral appliance application in treating OSAHS.

Camouflage Treatment In Adult Patient With Mandibular Lateral Displacement, Transverse Deficiency And Facial Asymmetry – A Case Report, Yu-Ling Tsai, Chun-Liang Kuo, I-Hua Liu

Taiwanese Journal of Orthodontics

Facial asymmetry is common in humans. Significant facial asymmetry causes both functional as well as esthetic problems. The etiologies of facial asymmetry include congenital disorders, acquired diseases, and traumatic and developmental deformities. The causes of many cases of developmental facial asymmetry are indistinct. The principle of facial asymmetry management would be correcting the underlying disorder. Orthognathic surgery is the first and better choice if face correction is the primary consideration. Camouflage orthodontic treatment was a non-invasive option for mild to moderate severity of asymmetry. We present a case with mandibular lateral displacement, transverse deficiency and facial asymmetry in a 19-year-old …

The role of facial growth and dentoalveolar development, and growth intensity will be discussed as they relate to treatment outcome. A retention protocol for early treatment with functional appliances will be suggested.

Dental Pulp Response To Orthodontic Tooth Movement, Chih-Wei Wang, Kai-Long Wang, Kwok-Hing Ho, Shun-Chu Hsieh, Heng-Ming Chang

Taiwanese Journal of Orthodontics

Pulp vitality may occasionally change while tooth experiencing orthodontic movement, and orthodontists are the particular group who concern this phenomenon if it happens. The respiration rate of dental pulp will be depressed inevitably in short term when tooth is subject to orthodontic force. If force level is extreme, circulatory interruption can occur and further induce pulp necrosis. When orthodontic movement on pulpalcompromised teeth (e.g. teeth with trauma history or large restorations) is required, the pulp response to orthodontic force should be monitored. This article provides an overall review on the pulpal reactions during orthodontic movement and dental movement on teeth …

Surgical-Orthodontic Treatment With Molar Protraction In A Patient With Skeletal Class Iii Anterior Open Bite And Facial Asymmetry, Yi-Hsuan Chen, Cheng-Hui Lin, Ellen Wen-Ching Ko

Taiwanese Journal of Orthodontics

A 20-year-old young male complained of his protrusive and deviated chin. He also presented occlusal plane cant, anterior open bite and unrestorable maxillary right first molar and mandibular left first molar. The severe maxilla-mandibular discrepancy was solved with surgery-first double jaw orthognathic surgery. The space of two extracted first molars was closed by protraction of the second and third molars after surgery. Two protraction techniques were used in this case, including closing maxillary right first molar space with reciprocal retraction, and closing mandibular left first molar with one miniscrew as an absolute anchorage. Careful biomechanical consideration was used during protraction …

Nitrosative Stress Sensing In Porphyromonas Gingivalis: Structure And Function Of The Heme Binding Transcriptional Regulator Hcpr, Benjamin R. Belvin

Theses and Dissertations

Porphyromonas gingivalis, a Gram negative anaerobe implicated in the progression of periodontal disease, is capable of surviving and causing infection despite high levels of reactive nitrogen species found in the oral cavity due to its efficient nitrosative stress response. HcpR is an important sensor-regulator that plays a vital step in the initiation of the nitrosative stress response in many Gram negative anaerobic bacteria. We employ a combination of X-ray crystallography, SAXS, resonance Raman spectroscopy, UV-Vis spectroscopy, and molecular biology techniques to better understand this key regulator. Knockout of the hcpR gene in W83 P. gingivalis results in the inability of …
