RESUMO
Introduction: Cone beam computed tomography (CBCT) is often used in pre-implant planning where it helps assessing theamount of bone availability and its relationship from its surrounding structures. In certain vital areas such as inferior alveolarnerve canal and submandibular gland fossa, it is important to know the dimensions of the bone to avoid post-operativecomplications. The aim of the study was to evaluate the deepest area or the concavity depth submandibular fossa on CBCTand also to measure/determine the distance from the mental foramen to the deepest concavity depth and the height of alveolarcrest from the deepest concavity depth.Materials and Methods: Retrospective studies of CBCT images were obtained on a KODAK 9000 three-dimensional (3D)extraoral imaging systems using CS 3D imaging software. The site of the submandibular gland fossa was identified, andmeasurements were done to evaluate the depth of the fossa, its distance from the alveolar crest and from the mental foramen.Results: The lingual concavity depth over a range up to a maximum value of 3.70 mm and the minimum depth up to 0.5 mm.Analysis of variance compared the mean values and standard deviation for mandibular measurements between male and female.The sexes did not differ significantly. Independent sample t-test did not demonstrate any difference among the age group,#P > 0.05.Conclusion: CBCT is an important tool for assessing the mandibular region and planning for safe implant placement in theposterior mandible.
RESUMO
Retropharyngeal abscess (RPA) is an infection in the retropharyngeal space of neck. It is rare in adults and can occur as a result of local trauma, foreign body ingestion, or instrumental procedures. Abscesses in this space can be caused by aerobic, anaerobic, or Gram-negative organisms. Salmonella neck infections represent an uncommon cause of focal salmonellosis. It may develop in uncontrolled diabetic or immunocompromised, patients without any proceeding intestinal manifestation of the disease. While the incidence of non-typhoidal salmonellosis (NTS) is estimated at over two million cases annually, extra intestinal manifestation account in less than 1 % of these cases. Here, we report a case of RPA due to Salmonella enterica subp. enterica serovar Typhimurium in a 50-year-old female from Central India. IV antibiotics should be considered along with surgical drainage and treatment of the comorbidity. Early diagnosis and intervention are imperative to avoid mortality.
RESUMO
Keratocystic odontogenic tumor (KCOT), also known as odontogenic keratocysts, as defined by World Health Organization (WHO), are known for their peculiar behavior, varied origin, debated development, unique tendency to recur, and disputed treatment modalities. We present a case of KCOT involving symphysis menti, right and left halves of the body of mandible in an 11-year-old girl treated with enucleation and open dressing (bismuth, iodoform, paraffin paste) with long-term follow-up.
