Chulalongkorn University Theses and Dissertations (Chula ETD)

The number of older adults in Thailand is currently increasing. To create the appropriate oral health service for them requires understanding the associations between dental service utilization (DSU), oral status and oral health-related quality of life (OHRQoL). The objectives of this study were to examine the associations of DSU and oral status with OHRQoL and to examine the associations between social backgrounds and DSU in Thai older adults. Data on 4,130 Thai older adults from the 8th Thailand National Oral Health Survey were collected through interviews and oral examination. Chi-square test and multiple logistic regression models were applied. Thai older …

A Comparison Of Microrna Profiles Between Rat Incisors And Molars, Sirawit Nipakasem

Chulalongkorn University Theses and Dissertations (Chula ETD)

Unlike the molar, rodent incisor is a distinct organ that have continuously growth at distal end of tooth throughout its lifetime to compensate for abrasion. The key of continuous growth is the result of delayed root formation and prolonged crown formation that possibly made by stem cell niche, so-called cervical loop, which involve various genes and signaling pathways. MicroRNAs (miRNAs) are small non-coding single stranded RNAs that involved in biological mechanisms of dental development. To study the role of miRNA, we extracted total RNA from the dental pulp tissue collected from the apical part, coronal part of incisors and molars, …

Oral Health-Related Quality Of Life And Related Factors In The Elderly Patients Who Received Dental Treatment, Teerawut Tatiyapongpaiboon

Chulalongkorn University Theses and Dissertations (Chula ETD)

This thesis is a cross-sectional study which explores underlying determinants of elderly patients. The study examines related factor that impaired Oral Health-related Quality of life (OHRQoL) and analyzes the characteristics of elderly patients at our clinic. 46 participants are patients who completed dental treatment more than 6 months during May 2016 to December 2018. Underlying determinants information were recorded by interview, patient chart review and oral examination. There were collected self-evaluation and Oral Impacts on Daily Performances (OIDP). Descriptive statistics was used to describe the characteristics of patients. Spearman correlation and Kruskal-Wallis test at P-value < 0.05 were performed. From the results, the participant’s OIDP scores showed the majority in no severity and no more than 2 impacts activities. The major activities that were impacted were eating activity and speaking activity due to ill-fitting dentures but less impacts in psychological and social performance. There was poor denture satisfaction that impaired participant’s OHRQoL. However, there were differences between dentist and patient evaluation. The authors suggest that the dental treatment should focus on the recall system, the frequency of dental recall visits, procedures to successful oral hygiene instruction and skills to handle the denture problems.

Protein Expression And Inflammatory Response After Delivery Of Mrna Encoding Platelet-Derived Growth Factor-Bb In Sucrose Citrate Buffer Into Rat Gingiva, Phan Bhongsatiern

Chulalongkorn University Theses and Dissertations (Chula ETD)

Messenger RNA (mRNA) has emerged as a novel therapeutic modality in medical fields, including regenerative medicine. The concept of mRNA-based therapy is to use synthesized mRNA encoding therapeutic protein delivered to target tissue. Thus, mRNA encoding growth factor could be a promising alternative to recombinant protein. Platelet-derived growth factor (PDGF) is one of most extensively studied growth factors for periodontal regeneration. To date, mRNA therapy has never been explored in the field of periodontal regeneration. The aim of the study is to examine the effect of nucleoside-modified mRNA encoding PDGF-BB on the level of PDGF-BB protein and inflammatory response at …

The Use Of Modified Mrna Encoding Platelet-Derived Growth Factor-Bb As An Innovation In Periodontal Regeneration, Theeraphat Surisaeng

Chulalongkorn University Theses and Dissertations (Chula ETD)

Since the mRNA platform has been recently introduced to several fields in medicine and the achievement of periodontal regeneration is currently unpredictable, therefore, the use of mRNA technology is a promising approach to pursue the complete periodontal regeneration. The aims of this study are to learn if mRNA encoding platelet-derived growth factor-BB (PDGF-BB) induces PDGF production in human periodontal ligament cells (PDLCs) and to investigate the effect of secreted PDGF on PDLC proliferation and promoting endothelial cell tube formation. PDLCs were obtained from extracted teeth of healthy periodontal patients. The N1-methylpseudouridine modified mRNA encoding PDGF-BB were transfected into PDLCs. The …

The Effect Of Change In Medi-Cal Dental Coverage On Dental Care Utilization Among Medi-Cal Beneficiaries, Min H. Zhang

Theses and Dissertations

One of the most important factors in accessing dental care is having dental insurance. For people with low incomes, Medicaid is the main source of health insurance. Medi-Cal is California’s Medicaid program. Adult dental services were mostly eliminated in Medi-Cal in 2009 due to the economic downturn and partially restored in 2014. The objective of this study is to evaluate the effect of change in Medi-Cal dental coverage, specifically the partial restoration of adult dental coverage in 2014, on dental care utilization among Medi-Cal beneficiaries. The partial restoration significantly increased the utilization rates in dental clinics from 2014 to 2017 …

The Effect Of Quercetin In Periodontal Inflammation, Sara Holden

Theses and Dissertations

Purpose: To determine the effect of Quercetin, a plant based over the counter flavonoid, on periodontal inflammation in a murine model of periodontitis.

Methods: Periodontitis was induced in age and gender matched mice (C57BL/6) using ligatures on the left side of the maxilla and right side was left un-ligated as baseline control. The animals received daily Quercetin gavage or Phosphate Buffered Saline (PBS) starting 5 days prior to ligation which continued throughout the experimental protocol. Micro-computed tomography (micro CT) imaging was used to determine alveolar bone loss. Real Time quantitative (qRT) PCR was used to determine level of gingival tissue …

Impact On The Pharyngeal Airway Space After Maxillomandibular Advancement Procedure For Obstructive Sleep Apnea Patients, Ghaddy Alsaty

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder, characterized by disrupted snoring and repetitive upper airway obstructions. Continuous positive airway pressure (CPAP) is considered the therapeutic mainstay for OSA patients. However, CPAP therapy has compliance limitations. An alternative treatment options is maxillomandibular advancement (MMA) surgical procedure. Genial tubercle advancement (GTA) is often performed concomitant with MMA for esthetic purposes. Cone-beam computed tomography (CBCT) provides the ability to visualize the upper airway and perform three-dimensional (3D) reconstructions. The purpose of this study is to evaluate the impact of MMA procedure with or without GTA on oropharyngeal …

Background and Objectives: In today’s time, there is an increasingly crowded field of competition vying over a small subset of the population. Now, more than ever it is imperative to compete with efficiency and esthetics. Each step for orthodontic bonding procedures increases the chance for error to occur. However, orthodontic bracket, etchant, sealant, and adhesive material has the ability to improve bond strength and final outcome for the patient and provider. The aim of this study was to determine effective bonding protocols for Advanced Clarity APC™ Flash-Free Brackets and to determine if adhesive remains on enamel or orthodontic bracket after …

Judged Facial Attractiveness Of Extraction And Non-Extraction Orthodontic Treatment In Repose And Smiling, Nicolette R. Chahin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: More so than ever, the public is becoming exceedingly aware of esthetics, and will evaluate their treatment outcome based upon the improvement to their smile and overall enhancement of their facial appearance. There exists a debate in orthodontics, as to whether or not extractions harm the profile. The aim of this study was to determine if facial attractiveness is harmed in subjects having completed orthodontic treatment involving the extraction of four premolars both in repose and smiling when viewed in lateral profile. Another objective is to identify any impact upper incisor retraction has on facial attractiveness. …
