Predictors of Osteoradionecrosis Following Irradiated Tooth Extraction

Radiat Oncol (2021) 16:130 https://doi.org/10.1186/s13014-021-01851-0 RESEARCH Open Access Predictors of osteoradionecrosis following irradiated tooth extraction Szu Ching Khoo1, Syed Nabil1, Azizah Ahmad Fauzi2, Siti Salmiah Mohd Yunus1, Wei Cheong Ngeow3 and Roszalina Ramli1* Abstract Background: Tooth extraction post radiotherapy is one of the most important risk factors of osteoradionecrosis of the jawbones. The objective of this study was to determine the predictors of osteoradionecrosis (ORN) which were associated with a dental extraction post radiotherapy. Methods: A retrospective analysis of medical records and dental panoramic tomogram (DPT) of patients with a history of head and neck radiotherapy who underwent dental extraction between August 2005 to October 2019 was conducted. Results: Seventy-three patients fulflled the inclusion criteria. 16 (21.9%) had ORN post dental extraction and 389 teeth were extracted. 33 sockets (8.5%) developed ORN. Univariate analyses showed signifcant associations with ORN for the following factors: tooth type, tooth pathology, surgical procedure, primary closure, target volume, total dose, timing of extraction post radiotherapy, bony changes at extraction site and visibility of lower and upper cortical line of mandibular canal. Using multivariate analysis, the odds of developing an ORN from a surgical procedure was 6.50 (CI 1.37–30.91, p 0.02). Dental extraction of more than 5 years after radiotherapy and invisible upper cortical line of mandibular canal= on the DPT have the odds of 0.06 (CI 0.01–0.25, p < 0.001) and 9.47 (CI 1.61–55.88, p 0.01), respectively. -

During this time the understanding of the disease has developed in the curriculum of the medical profession. Since 1922, when first described as a clinical entity by Schultz, it has been reported more frequently as the years passed until at the present time agranulocytosis is recognized widely as a disease process. Just as with the development of any medical problem this has been laden with various opinions on its course, etiology, etc., all of which has served to confuse the searching medical mind as to its true standing. -
Chronic Actinomycosis of the Cervical Lymph Node Simulating a Thyroid Neoplasm

This will allow community-based practitioners to more effectively manage patients in their practices. It is well known that the maintenance of good oral health is important in cancer patients, including patients with hematologic malignancies. Oral pain and/or infections can cause delays, reductions or discontinuation of life-saving cancer treatment. Poor oral health can also lead to negative impacts on a patient’s quality of life including psychological distress, social isolation and inadequate nutrition. -
Computed Tomography of the Buccomasseteric Region: 1
605 Computed Tomography of the Buccomasseteric Region: 1. Anatomy Ira F. Braun 1 The differential diagnosis to consider in a patient presenting with a buccomasseteric James C. Hoffman, Jr. 1 region mass is rather lengthy. Precise preoperative localization of the mass and a determination of its extent and, it is hoped, histology will provide a most useful guide to the head and neck surgeon operating in this anatomically complex region. Part 1 of this article describes the computed tomographic anatomy of this region, while part 2 discusses pathologic changes. The clinical value of computed tomography as an imaging method for this region is emphasized. The differential diagnosis to consider in a patient with a mass in the buccomas seteric region, which may either be developmental, inflammatory, or neoplastic, comprises a rather lengthy list. The anatomic complexity of this region, defined arbitrarily by the soft tissue and bony structures including and surrounding the masseter muscle, excluding the parotid gland, makes the accurate anatomic diagnosis of masses in this region imperative if severe functional and cosmetic defects or even death are to be avoided during treatment. An initial crucial clinical pathoanatomic distinction is to classify the mass as extra- or intraparotid. Batsakis [1] recommends that every mass localized to the cheek region be considered a parotid tumor until proven otherwise. Precise clinical localization, however, is often exceedingly difficult. Obviously, further diagnosis and subsequent therapy is greatly facilitated once this differentiation is made. Computed tomography (CT), with its superior spatial and contrast resolution, has been shown to be an effective imaging method for the evaluation of disorders of the head and neck. -

It is a sporadic but common disease in cattle, occasional in pigs and horses and rarely in goats (Radostits et al., 2007). Members of the genus Actinomyces are Gram positive, non-acid fast, non-spore forming rods (Songer and Post, 2005) that form a mycelium of branching filaments that fragment into irregular-sized rods (Blood et al., 2007). The species that commonly cause disease in domestic animals include A. bovis, A. hordeovulneris, A. hyovaginalis, A. israelii, A. naeslundii, A. suis, A. viscosus and Arcanobacterium pyogenes (Songer and Post, 2005). Actinomyces bovis is a common inhabitant of the bovine mouth and infection is presumed to occur through wounds to the buccal mucosa caused by sharp pieces of feed or foreign material. Infection may also occur through dental alveoli, and may account for the more common occurrence of the disease in young cattle when the teeth are erupting (Radostits et al., 2007). Actinomyces viscosus causes periodontal disease and subgingival plaques in hamsters fed a high carbohydrate diet, and also abscessation in dogs (Timoney et al., 1988) in which it is an opportunistic infection (Blood et al., 2007). -

Improving Mouth Care for Adult Patients in Hospital Mouth Care for Adult Patients in Hospital / Vers 5 (07/13) This resource is for nurses, health care support workers and other health care professionals (for example, doctors, respiratory physiotherapists, speech and language therapists, dieticians) who provide or give advice on mouth care for adult patients in hospital. It is designed to Improve oral health knowledge and skills for health care professionals who support patients in hospital and those living with complex medical conditions and advanced illness. Enable health care professionals to provide and deliver a high standard of mouth care for adult patients in hospital. Support person centred training, and to suit individual needs and local circumstances. Support hands on training and teaching, and will be helpful for health and care professionals who find it difficult to clean a patients mouth. Learning Outcomes 1 Demonstrate an understanding of why good oral health is important for patients in hospital 2 Recognise risk factors that contribute to poor oral health and the association with systemic disease 3 Identify risk factors associated with Dental Caries (tooth decay) 4 Identify risk factors associated with Gingivitis and Periodontitis (gum disease) 5 Understand the mouth care documentation (e.g. mouth care risk assessment, care plans and documentation forms) 6 Complete a mouth care risk assessment / care plan 7 Process and report any oral health concerns (depending on local protocols) 8 Identify techniques and strategies that may help patients with challenging behaviour or who resist oral care / are unable to co-operate 9 Recognise the need for specialised mouth care / support for patients who require assistance Mouth Care for Adult Patients in Hospital / Vers 5 (07/13) This resource is in several sections, some of which can be used on their own. -
