Dental implant failure possibly attributed to embedded pencil graphite: first clinical report.

Implant failures have been associated with a diversity of etiologic processes, predominately arising from bone loss (peri-implantitis) due to inadequate maintenance of oral hygiene or excess luting agents. The aim of this article is to report a novel case of the apparent failure of a dental implant to undergo osseointegration in the presence of submerged pencil graphite. Practitioners are advised to carefully evaluate the clinical and radiographic site of a proposed implant for occult foreign substances.

Prevention of intrusion of natural teeth surrounded by freestanding implants.

Intrusion is frequently observed as a complication associated with tooth-implant-supported prostheses: the natural tooth that serves as an abutment moves apically and out of occlusion. However, intrusion of teeth proximal to implants has yet to be reported in the literature. In this manuscript, three presentations of tooth intrusion proximal to implants are reported; potential causes of the phenomenon are discussed; and a potential treatment for patients experiencing this condition is presented.

Spindle cell lipoma of the buccal mucosa: Uncommon finding in an older adult.

Objective: This article reports a case of a longstanding, slowly enlarging intraoral spindle cell lipoma (SCL) that had become increasingly painful during mastication.

Background: The SCL represents an uncommon variant of the conventional lipoma. There is limited information regarding this lesion in the gerodontologic literature.

Acaricidal activity, mode of action, and persistent efficacy of selected essential oils on the poultry red mite (Dermanyssus gallinae).

In this work, the essential oils (EOs) from Litchi chinensis, Clausena anisata, Heracleum sphondylium, Pimpinella anisum, Lippia alba, Crithmum maritimum and Syzygium aromaticum were tested for their contact toxicity against the poultry red mite, Dermanyssus gallinae, a deleterious ectoparasite of aviary systems. In addition, in order to give insights on their mode of action and effectiveness, the vapor phase and residual toxicity tests were also performed. Results showed that amongst all the tested EOs, that of S.

Trigeminal herpes zoster and Ramsay Hunt syndrome in an elderly adult: Presentation with prodromal toothache.

Objective: This article describes an atypical herpes zoster (HZ) infection heralded by prodromic dental pain.

Background: Trigeminal HZ is associated with any of the three divisions of the trigeminal nerve, and Ramsay Hunt syndrome is a rare variant of HZ infection of the ear, often accompanied with unilateral facial nerve palsy.

Materials And Methods: An 87-year-old man sought remedy for tooth-like pain.

Graphene oxide/silver nanohybrid: Optimization, antibacterial activity and its impregnation on bacterial cellulose as a potential wound dressing based on GO-Ag nanocomposite-coated BC.

Recently, bacterial cellulose (BC) based wound dressing have raised significant interests in medical fields. However, to our best knowledge, it is apparent that the BC itself has no antibacterial activity. In this study, we optimized graphene oxide-silver (GO-Ag) nanohybrid synthesis using Response Surface Methodology and impregnate it to BC and carefully investigate their antibacterial activities against both the Gram-negative bacteria and the Gram-positive bacteria .

Intraoral chemical burn from use of 3% hydrogen peroxide.

Injudicious use of over-the-counter 3% hydrogen peroxide, a relatively potent oxidative agent, can result in a chemical burn to the oral mucosa. This article describes a patient who rinsed with 3% hydrogen peroxide for periods of more than two minutes as a self-prescribed remedy for oral discomfort following seafood ingestion. Subsequently, the patient experienced pain and extensive chemical burns of the sublingual and buccal mucosa and gingiva.
