Improved Quality of Living following Simultaneous Condylectomy and Orthognathic Surgery: A Retrospective Analysis for Active Unilateral Condylar Hyperplasia

alwin shared this article with you from Inoreader Improved Quality of Living following Simultaneous Condylectomy and Orthognathic Surgery: A Retrospective Analysis for Active Unilateral Condylar Hyperplasia Via Journal of Oral and Maxillofacial Surgery The objective was to assess quality of life in patients who underwent simultaneous condylectomy and orthognathic surgery in conjunction with orthodontic treatment for active unilateral condylar (TMJ) hyperplasia. This pathologic process leads to the development of esthetic and functional concerns. High condylectomy (7-10mm of bone removed from condylar process) simultaneously performed with orthognathic surgery is the treatment studied1, but currently, there is no published literature that analyzes patient satisfaction.

Are Bacteria Just Bystanders in the Pathogenesis of Inflammatory Jaw Conditions?

alwin shared this article with you from Inoreader Are Bacteria Just Bystanders in the Pathogenesis of Inflammatory Jaw Conditions? Via Journal of Oral and Maxillofacial Surgery It is unclear whether certain bacteria initiate the development of inflammatory jaw conditions, or whether these diseases create a milieu for dysbiosis and secondary colonization of indigenous flora. At present, there are no comparative studies on the types of bacteria that colonize different inflammatory jaw conditions. Accordingly, this study aims to identify and compare the types of bacteria isolated in osteomyelitis, osteoradionecrosis, and MRONJ.

Oral Rehabilitation of an Adult Cleft Palate Patient with Zygomatic Implant-supported Obturator Prosthesis: A Case Report

alwin shared this article with you from Inoreader Oral Rehabilitation of an Adult Cleft Palate Patient with Zygomatic Implant-supported Obturator Prosthesis: A Case Report Via Journal of Oral and Maxillofacial Surgery With advancement in medical services and their accessibility across the country, as well as growing awareness among the patient population, it is rare to find an adult with an untreated cleft lip and/or palate nowadays. Treatment of these patients to restore form and function can be challenging, often yielding less-than-satisfactory outcomes. In current literature, there have been case reports of patients with atrophic maxilla or severe maxillary defects after oncologic resections, where zygomatic implants have been utilized for fabrication of a fixed maxillary prosthesis.

Intraoperative flap warming: The novel use of a sterile cardiac forced warm air blanket for maintaining optimal flap perfusion.

alwin shared this article with you from Inoreader Intraoperative flap warming: The novel use of a sterile cardiac forced warm air blanket for maintaining optimal flap perfusion. Via Journal of Oral and Maxillofacial Surgery The two-team approach in major head and neck/reconstructive surgery can occasionally lead to delays between flap harvest and detachment, due to the complexity and length of the ablative procedure. In order to minimize the potential for flap cooling and the adverse impact on microcirculation, active warming can be beneficial.(1) Intraoperative flap warming to either maintain or improve circulation during free flap harvesting has been performed with a variety of passive and active techniques,(2) however limitations such as a lack of consistent temperature regulation, lack of sterility, inability to directly visualise the flap or the need for acquisition of new equipment for a niche area meant that an ideal solution was lacking.

Augmentation of the width and thickness of keratinised gingiva using a collagen biomaterial in apically positioned flap surgery: A technical note

alwin shared this article with you from Inoreader Augmentation of the width and thickness of keratinised gingiva using a collagen biomaterial in apically positioned flap surgery: A technical note Via The British Journal of Oral and Maxillofacial Surgery To ensure that dental implants remain functional in the long-term, adequate thickness and width of keratinised tissue at the cervical collars are essential.1 Once a tooth is lost, the height of the alveolar bone is reduced, and the keratinised tissue of the edentulous area recedes.2 There are two techniques currently used to obtain the desired keratinised tissue augmentation: the apically positioned flap surgery and the free gingival graft surgery.2 The apically positioned flap surgery, the existing keratinised tissue is incised at the mucosal or mucoperiosteal flap to enable natural extension of the incised end.

SEARCH FOR EXPERIMENTAL EVIDENCE OF DOSE-RATE AND WALL SCATTERING EFFECTS IN THE THERMOLUMINESCENCE RESPONSE OF LIF:MG,TI (TLD-100)

alwin shared this article with you from Inoreader SEARCH FOR EXPERIMENTAL EVIDENCE OF DOSE-RATE AND WALL SCATTERING EFFECTS IN THE THERMOLUMINESCENCE RESPONSE OF LIF:MG,TI (TLD-100) Via Radiation Protection Dosimetry Abstract An experimental investigation into the possibility of dose-rate effects and wall scatter in the thermoluminescent response of LiF:Mg,Ti (TLD-100) was carried out. The investigation was motivated by theoretical simulations predicting the possible presence of dose-rate effects coupled with the lack of detailed experimental studies. The dose rate was varied by changing the source to sample distance, by the use of attenuators, sources of 137Cs of various activities, filtration and the construction of identical geometrical irradiators of Teflon and stainless steel. Four levels of dose in the linear dose response region were studied at 10−2 Gy, 1.5 × 10−2 Gy, 0.1 Gy and 0.5 Gy to avoid complications in interpretation due to supralinearity above 1 Gy. At the dose of 1.5 × 10−2 Gy, the dose rate was varied by five orders of magnitude from 4.9 × 10−3 Gy s−1 to 4.9 × 10− 8 Gy s−1. At the other levels of dose, a one to two orders of magnitude in dose rate was achieved. Within the measurement uncertainty of 5–10%, no dose-rate effects were observed in any of the experimental measurements and no changes in the shape of the glow curve were observed. The maximum wall scatter effect (Teflon to stainless steel) was measured at ~8% within the experimental uncertainty and well below expectations. The results are encouraging with respect to the accurate and reproducible use of LiF:Mg,Ti under various experimental conditions of irradiation. View on the web Inoreader.

DESIGN AND FABRICATION OF A PEDIATRIC THYROID PHANTOM FOR USE IN RADIO-IODINE UPTAKE MEASUREMENT, IMAGE QUALITY CONTROL AND DOSIMETRY

alwin shared this article with you from Inoreader DESIGN AND FABRICATION OF A PEDIATRIC THYROID PHANTOM FOR USE IN RADIO-IODINE UPTAKE MEASUREMENT, IMAGE QUALITY CONTROL AND DOSIMETRY Via Radiation Protection Dosimetry Abstract Estimating internal contamination from 131I for children in nuclear accidents is a crucial subject in the radiation protection field. Throughout this paper, an urgent and simple method was proposed for measuring 131I inside the pediatric thyroid gland by constructing a neck and thyroid phantom. For this purpose, CT scan images of healthy child's thyroids were obtained, and the sizes of different parts were determined by a 3D slicer image processing software. Girls with the body surface area between 0.95 and 1.05 were involved in this study. The fabricated phantom is composed of 5 cylindrical slabs of 2-cm thickness, and several small holes were constructed for TLD dosemeters near the thyroid gland and all other parts of the neck. The phantom was constructed utilizing a 3D printer with acrylonitrile butadiene styrene plastic. The thyroid phantom was filled with radioiodine-131, and calibration curves were plotted for contam ination estimation. A nodular thyroid phantom was also constructed. The nodular phantom or the resolution phantom has 4 removable parts containing cylindrical holes with diameters of 3, 6, 9 and 12 mm. These holes on the thyroid glands can be filled with different activities of radionuclides to serve as hot and cold spots for quality control of nuclear medicine images. The results show that the designed phantom is applicable in different fields such as nuclear image quality and resolution tests, dosimetry and iodine thyroid uptake estimation in nuclear medicine departments, and nuclear emergency monitoring.
