Chapter
Aim The purpose of this study is to carry out a three-year retrospective study on the use of autologous Concentrated Growth Factor (CGF) on dental patients undergoing oral regenerative treatment. Materials and methods Data was gathered from 46 patients who received oral regenerative therapy using CGF within the last three years in a private dental...
Chapter
Introduction Application of pure oxygen is an easy method to overcome gagging. Aim The objective of this paper is to carry out a ten-year retrospective case series on the application of oxygen on gagging patients diagnosed with sleep disordered breathing (SDB). Materials and methods A cohort of 62 private dental patient data was collected for the s...
Chapter
Introduction Overcoming a dental implant failure/osseo-disintegration is still a dilemma for implantologists. Using two implants to support for one crown is a novel approach to resolve this issue. Aim The aim of this study is to carry out a five-year retrospective study on how to overcome shortfalls in single implant failures by using two small imp...
Chapter
Aim This report intends to illustrate the different outcomes between a dental implant and transplant. Materials and methods Our literature review showed 812 papers related to the use of concentrated growth factors (CGF) in implantology, but none of them report on the study of the application of CGF on dental implant and transplant. Therefore, this...
Conference Paper
Background The surgical placement of implants into maxillary extraction sites in ovariectomized (OVX) rats could mimic implant placement in compromised bone in humans, such as is seen in osteoporosis. Purpose This study was designed to evaluate the effects of osteoporosis on osseo-integration around titanium implants following extraction in the pos...
Conference Paper
There are many clinical situations where it is not possible to be certain if a patient is experiencing pain. A urinary biomarker of pain would expedite diagnosis and treatment. The collection of urine is non-invasive, which makes it an ideal choice in situations where patients are stressed and already suffering pain. This systematic review aims to...
Conference Paper
Electroencephalography (EEG) has been used to investigate cortical mechanisms involved in pain, to diagnose pain conditions, and to monitor therapeutic outcomes. The purpose of this systematic review is to determine if EEG has been validated for use in the investigation of the mechanisms, diagnosis, and monitoring of therapeutic indices involving c...
Conference Paper
Collagen meshwork, proteoglycans and fluid are the three main components in articular cartilage type II. They have been commonly simulated indirectly via Young’s modulus in loads of numerical studies recently in which collagen meshwork and proteoglycans are mainly responsible the dynamic compressive, tensile response and the static (equilibrium) co...
Conference Paper
Objective This study aims to evaluate the relationship between implant placement, poor quality bone, simvastatin, and osseo-integration of surface-treated implants in the posterior maxilla of osteoporotic rats. Materials and methods Sixty-four female Sprague-Dawley rats, aged 3 months old were used in this study, divided into three groups: Sham-ope...
Conference Paper
The purpose of this study is to evaluate the therapeutic effects of MLS laser on clinical outcomes of flapless dental implants placed using split mouth study and to measure patients’ satisfaction using visual analogue scale in in post menopause women age 50 years or over. Materials and methods: This study is a retrospective split mouth study on the...
Article
The aim of this study is to perform a comprehensive evaluation of clinical procedures used in dental implant treatment in posterior maxilla using flapless technique; to assess osseo-integration of surface-treated implants in the posterior maxilla of osteoporotic (OP) rats, and the conservative regeneration of poor quality bone in (OP) rats with sim...
Article
The aim of this study is to examine the clinical outcomes of implants inserted using split mouth study and to measure patients’ satisfaction using visual analogue scale in flapless and conventional flap techniques in post menopause women age 50 years or over. Materials and methods: This study is a retrospective split mouth study of flapless vs flap...
Article
This article reviews the literature on the outcome of flapless surgery for dental implants in the posterior maxilla. The literature search was carried out in using the keywords: flapless, dental implants and maxilla. A hand search and Medline search were carried out on studies published between 1971 and 2011. The authors included research involving...
Article
Objective: Simvastatin has been shown to enhance osseointegration of pure titanium implants in osteoporotic rats. This study aimed to evaluate the relationship between the serum level of bone formation markers and the osseointegration of pure titanium implants in osteoporotic rats treated with simvastatin. Materials and methods: Fifty-four femal...

The aim of this study was to evaluate the healing of class III furcation defects following transplantation of autogenous periosteal cells combined with beta-tricalcium phosphate (beta-TCP). Periosteal cells obtained from Beagle dogs' periosteum explant cultures, were inoculated onto the surface of beta-TCP. Class III furcation defects were created...

Anaerobic bacteria play important roles in the pathogenesis of human periodontitis. This study examined the relationship between a potentially new periodontopathic bacterium Dialister pneumosintes and periodontal disease. A total of 73 women and 62 men aged 18 to 86 years participated in the study. Using a 16S rRNA polymerase chain reaction identif...

Full-text available
Dialister pneumosintes is a nonfermentative, anaerobic, gram-negative rod that grows with small, circular, transparent, shiny, smooth colonies on blood agar. Even though D. pneumosintes has been recovered from deep periodontal pockets, little is known about the relationship between the organism and destructive periodontal disease. This study descri...
Article
Therapeutic angiogenesis is the controlled induction or stimulation of new blood vessel formation to reduce unfavourable tissue effects caused by local hypoxia and to enhance tissue repair. The effects of ultrasound on wound healing, chronic ulcers, fracture healing and osteoradionecrosis may be explained by the enhancement of angiogenesis. The aim...
Article
The aim of this study was to evaluate several in vitro effects of ultrasound that could revert or prevent the hypoxia, hypovascularity, and hypocellularity observed in osteoradionecrosis. Two different ultrasound machines were evaluated, a "traditional" (1 MHz, pulsed 1:4) and a "long wave" (45 kHz, continuous) machine, tested at various intensitie...

Anaerobic culture is employed routinely in the primary isolation of periodontal pathogenic bacteria. However, little or no data exist on the relative abilities of the Coy anaerobic chamber (Coy Laboratory Products, Grass Lake, Mich.), the GasPak (Becton Dickinson Microbiology Systems, Cockeysville, Md.), and the AnaeroPack (Mitsubishi Gas Chemical...
Article
Mandibular osteoradionecrosis is a serious chronic complication which may follow radiotherapy. Therapeutic ultrasound is a highly effective, inexpensive and readily available means of promoting revascularisation and healing. 'Long wave' ultrasound increases penetration depth and, therefore, seems to be more appropriate than traditional high frequen...
