BACKGROUND: Total tooth loss (edentulism) can be a debilitating condition, impacting on ability to chew, speak and interact with others. The most common treatment is with complete removable dentures, which may be successful, but in the lower jaw, bone resorption that worsens over time makes denture-wearing difficult. Two dental implants in the mandible to retain the lower denture has been advocated as the gold standard of treatment, but has not been universally provided due largely to financial constraints and also patient fear...

INTRODUCTION: The use of intermaxillary fixation (IMF) in the treatment of faciomaxillary fractures is the key factor for reduction and immobilization. Various techniques of IMF have been described in the past and recently IMF screws have been introduced. This technique has various advantages, including ease of use, less time consumption, less trauma to the surrounding soft tissues, and relatively reduced risk of needle stick injury. This study evaluates the efficacy of IMF screws over arch bar IMF before definitive fixation of facial fractures...

REVIEW
Harry Liu, Chengbiao Wu
Charcot-Marie-Tooth 2B peripheral sensory neuropathy (CMT2B) is a debilitating autosomal dominant hereditary sensory neuropathy. Patients with this disease lose pain sensation and frequently need amputation. Axonal dysfunction and degeneration of peripheral sensory neurons is a major clinical manifestation of CMT2B. However, the cellular and molecular pathogenic mechanisms remain undefined. CMT2B is caused by missense point mutations (L129F, K157N, N161T/I, V162M) in Rab7 GTPase. Strong evidence suggests that the Rab7 mutation(s) enhances the cellular levels of activated Rab7 proteins, thus resulting in increased lysosomal activity and autophagy...

Foreign body ingestion is common, although perforation after ingestion is rare. We report a case of an ingested sharp wooden stick that perforated the proximal jejunum toward the renal vasculature, causing segmental renal artery thrombosis and renal infarct. The patient presented with severe abdominal pain and vomiting. A computed tomography scan revealed a linear opacity corresponding to the foreign body. The wooden stick was removed endoscopically through deep-push enteroscopy with a rat-tooth forceps. We report this unique case of perforation by a foreign body through the proximal jejunum to the left kidney, which was managed endoscopically...

This clinical report describes a relatively infrequent patient with inferior alveolar nerve damage caused by foreign material within the mandibular canal, which is one of the most severe complications of endodontic therapy. Although the circumstance is uncommon, it can have extremely unfavorable consequences for patients, such as anesthesia and paresthesia. In the present case, a patient suffered pain and severe paresthesia in the corresponding area after routine endodontic therapy. Several treatments were conducted to relieve the patient's symptoms, ranging from medication to tooth extraction, but all were of no avail...

INTRODUCTION: Dental caries is the most widespread chronic infectious disease. Inflammation in pulp tissues caused by dental caries will lead to periapical granulomas, bone erosion, loss of the tooth, and severe pain. Despite numerous efforts in recent studies to develop effective treatments for dental caries, the need for a potent therapy is still urgent. METHODS: In this study, we applied a gene-based therapy approach by administering recombinant adeno-associated virus (AAV)-mediated Atp6v0d2 (d2) RNA interference knockdown of d2 gene expression to prevent periapical bone loss and suppress periapical inflammation simultaneously...

Bursera microphylla (BM), one of the common elephant trees, is widely distributed in the Sonoran desert in Mexico. The Seri ethnic group in the Sonoran desert uses BM as an anti-inflammatory and painkiller drug for the treatment of sore throat, herpes labialis, abscessed tooth, and wound healing. Dried stems and leaves of BM are used in a tea to relieve painful urination and to stimulate bronchial secretion. Furthermore, BM is used for fighting venereal diseases. To investigate the effects of the hexane fraction of resin methanol extract (BM-H) on cell growth, the acute myeloid cell line (OCI-AML3) was treated with 250, 25, or 2...
