  • Lumps and Swellings
    Clinical Oral medicine for the general practitioner: lumps and swellings Crispian Scully 1 his series of five papers summarises some of the most important oral medicine problems likely to be Tencountered by practitioners. Some are common, others rare. The practitioner cannot be expected to diagnose all, but has been trained to recognise oral health and disease, and should be competent to recognise normal variants, and common orofacial disorders. In any case of doubt, the practitioner is advised to seek a second opinion from a colleague. The series is not intended to be comprehensive in coverage either of the conditions encountered, or all aspects of Figure 1: Torus mandibularis. diagnosis or treatment: further details are available in standard texts, in the further reading section, or from the internet. The present article discusses aspects of lumps through fear, perhaps after hearing of someone with and swellings. ‘mouth cancer’. Thus some individuals discover and worry about normal anatomical features such as tori, the parotid Lumps and swellings papilla, foliate papillae on the tongue, or the pterygoid Lumps and swellings in the mouth are common, but of hamulus. The tongue often detects even a very small diverse aetiologies (Table 1), and some represent swelling, or the patient may first notice it because it is sore malignant neoplasms. Therefore, this article will discuss (Figure 1). In contrast, many oral cancers are diagnosed far lumps and swellings in general terms, but later focus on too late, often after being present several months, usually the particular problems of oral cancer and of orofacial because the patient ignores the swelling.

Intraoral removal could not be performed because of bilateral swellings on the lingual surface of the mandible. The patient was unable to recall when he first became aware of the lesions. He had no history of mandibular trauma or surgery. Phys- ical examination showed two symmetric, non- tender, bony outgrowths on the lingual surface of the mandible (Figure 1). We diagnosed man- dibular tori. Although the lesions were causing only minor symptoms, we elected to remove them to gain access to the Wharton duct. Torus mandibularis is a nontender, bony out- growth located on the lingual side of the man- dible, in the canine or premolar region, above the attachment of the mylohyoid muscle.

  • Abscesses Apicectomy
    BChD, Dip Odont. (Mondchir.) MBChB, MChD (Chir. Max.-Fac.-Med.) Univ. of Pretoria Co Reg: 2012/043819/21 Practice.no: 062 000 012 3323 ABSCESSES WHAT IS A TOOTH ABSCESS? A dental/tooth abscess is a localised acute infection at the base of a tooth, which requires immediate attention from your dentist. They are usually associated with acute pain, swelling and sometimes an unpleasant smell or taste in the mouth. More severe infections cause facial swelling as the bacteria spread to the nearby tissues of the face. This is a very serious condition. Once the swelling begins, it can spread rapidly. The pain is often made worse by drinking hot or cold fluids or biting on hard foods and may spread from the tooth to the ear or jaw on the same side. WHAT CAUSES AN ABSCESS? Damage to the tooth, an untreated cavity, or a gum disease can cause an abscessed tooth. If the cavity isn’t treated, the inside of the tooth can become infected. The bacteria can spread from the tooth to the tissue around and beneath it, creating an abscess. Gum disease causes the gums to pull away from the teeth, leaving pockets. If food builds up in one of these pockets, bacteria can grow, and an abscess may form. An abscess can cause the bone around the tooth to dissolve. WHY CAN'T ANTIBIOTIC TREATMENT ALONE BE USED? Antibiotics will usually help the pain and swelling associated with acute dental infections. However, they are not very good at reaching into abscesses and killing all the bacteria that are present.

  • Pathophysiological Mechanisms of Root Resorption After Dental Trauma: a Systematic Scoping Review Kerstin M
    Galler et al. BMC Oral Health (2021) 21:163 https://doi.org/10.1186/s12903-021-01510-6 RESEARCH ARTICLE Open Access Pathophysiological mechanisms of root resorption after dental trauma: a systematic scoping review Kerstin M. Galler1*, Eva‑Maria Grätz1, Matthias Widbiller1 , Wolfgang Buchalla1 and Helge Knüttel2 Abstract Background: The objective of this scoping review was to systematically explore the current knowledge of cellular and molecular processes that drive and control trauma‑associated root resorption, to identify research gaps and to provide a basis for improved prevention and therapy. Methods: Four major bibliographic databases were searched according to the research question up to Febru‑ ary 2021 and supplemented manually. Reports on physiologic, histologic, anatomic and clinical aspects of root resorption following dental trauma were included. Duplicates were removed, the collected material was screened by title/abstract and assessed for eligibility based on the full text. Relevant aspects were extracted, organized and summarized. Results: 846 papers were identifed as relevant for a qualitative summary. Consideration of pathophysiological mechanisms concerning trauma‑related root resorption in the literature is sparse. Whereas some forms of resorption have been explored thoroughly, the etiology of others, particularly invasive cervical resorption, is still under debate, resulting in inadequate diagnostics and heterogeneous clinical recommendations. Efective therapies for progres‑ sive replacement resorptions have not been established. Whereas the discovery of the RANKL/RANK/OPG system is essential to our understanding of resorptive processes, many questions regarding the functional regulation of osteo‑/ odontoclasts remain unanswered. Conclusions: This scoping review provides an overview of existing evidence, but also identifes knowledge gaps that need to be addressed by continued laboratory and clinical research.

    Opinion of Trustees Resolution of Dispute Case No. 88-122 Page 1 _____________________________________________________________________________ OPINION OF TRUSTEES _____________________________________________________________________________ In Re Complainant: Employee Respondent: Employer ROD Case No: 88-122 - October 3, 1989 Board of Trustees: Joseph P. Connors, Sr., Chairman; Paul R. Dean, Trustee; William Miller, Trustee; Donald E. Pierce, Jr., Trustee; Thomas H. Saggau, Trustee. Pursuant to Article IX of the United Mine Workers of America ("UMWA") 1950 Benefit Plan and Trust, and under the authority of an exemption granted by the United States Department of Labor, the Trustees have reviewed the facts and circumstances of this dispute concerning the provision of health benefits coverage for orthodontic treatment under the terms of the Employer Benefit Plan. Background Facts An oral surgeon states that the Employee's daughter began experiencing pain and popping in the right temporomandibular joint after being hit in the area of the right mandible during a fight in March 1985. She was treated by a physical therapist and had splint therapy to correct her temporomandibular joint problems for about six months. In August 1985, the Employee's daughter suffered a second injury to the right side of the head. She continued having pain and popping in the right temporomandibular joint, and surgery, an arthroplasty of the joint, was performed in December 1986. The Employer provided coverage for the physical therapy, the splint therapy and the surgery to correct her temporomandibular joint problems. In March 1988, an oral surgeon recommended orthodontic treatment to alleviate all of the Employee's daughter's symptoms. The Employee's daughter was examined by an orthodontist on May 10, 1988; he noted that she had reciprocal clicking in both temporomandibular joints, lack of proper chewing motion, limited mobility of the mandible, frequent headaches, and tenderness in the right jaw joint.
