Peri-Implantitis Incidence And Effect Of Supportive Periodontal Therapy On Outcomes: Retrospective Cohort Study, Michael Ha

Theses and Dissertations

Purpose: Management of peri-implantitis is becoming an increasing component of dental practice. Dental implants can develop peri-implantitis lesions which occur in a non‐linear and accelerating pattern compared to a gradual periodontitis lesion. It is crucial to diagnose and treat this disease early, or ideally prevent it. Contemporary implants have a rough surface texture which is difficult to properly decontaminate as a crucial component for treatment prognosis. Evidence on the long-term effects of Periodontal implant maintenance therapy (PIMT) on implants is limited. This study aims to investigate the effect of periodontal maintenance on peri-implant tissue health.

Methods: A retrospective chart review …

The Effect Of Biologic Materials And Oral Steroids On Radiographic And Clinical Outcomes Of Horizontal Alveolar Ridge Augmentation., Amy Reichert

Theses and Dissertations

The purpose of this study was to investigate if the addition of biologic materials and/or oral steroids would affect horizontal bone gain, or the bone density of the grafted bone in horizontal alveolar ridge augmentations. A retrospective chart review was completed to assess the clinical and radiographic outcomes of 53 ridge augmentation patients. An average bone gain of 3.6mm of width was found in our study based on radiographic analysis. There were no statistically significant differences found in the linear bone gain with the addition of biologic materials and steroids. A marginally statistically significant difference was found in the bone …

Novel Approach To Assess Periodontal Disease Severity Using Volumetric Analysis, Meera George Maveli

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate if the absolute change in linear measurements of bone loss on the facial plane of a maxillary central incisor at full and half root length along the vertical axis is directly proportional to volumetric change. The secondary aim was to evaluate if the variation of root volume is influenced by difference in root morphology.

Three dimensional digital models of 70 random patients were obtained from

DICOM CBCT files using volumetric software, InVivoDental (Anatomage, San Jose,

CA). One central incisor of average root length was selected per patient and total length

(L1) and …

Demographic Variables Affecting Patient Referrals From General Practice Dentists To Periodontists, Mark Roy Zemanovich

Theses and Dissertations

BackgroundWithin dentistry, a limited body of literature exists regarding the referral relationships between general practitioners (GPs) and specialists. The purpose of this study was to investigate the referral relationship between GPs and periodontists within the state of Virginia. MethodsA survey focused on the demographic variables in the referral relationship between GPs and periodontists was developed. The survey was mailed to 800 dentists throughout the state of Virginia. Descriptive statistics was completed along with multivariate logistic regression analysis comparing the responses with the number of patients referred per month to a periodontist. ResultsFemale respondents were more likely to refer three or …

The Prevalence Of The Need For Esthetic Crown Lengthening In Post Orthodontically Treated Subjects, David Clark Johnson

Theses and Dissertations

The problem of excess gingival display is difficult to diagnose and treat. By studying one aspect of excess gingival display, namely the size relationships of the clinical crowns of teeth, we can begin to quantify reasonable goals of therapy. In this study, two hundred plaster models were used as subjects. These represented two hundred patients before and after orthodontic therapy. The six anterior teeth were measured for length and width and compared to known ideals. Teeth that did not meet ideal standards may require treatment. It was found that the mean tooth length after orthodontic therapy was approximately two millimeters …
