The effect of education on dental service utilization patterns in different sectors: A multiple mediation analysis.

OBJECTIVE: The aim of this study was to investigate how education level affects dental service utilization patterns in the Australian adult population. This study tested how education level mediated these service patterns through behavioural mediators such as smoking, tooth brushing and oral health status and investigated these mediation effects in different dental service providers. METHOD: Following the flexible mediation approach, the direct and indirect effects of education through behavioural mediators on dental service utilization patterns (time of last dental visit, reason for last dental visit and frequency of seeking dental care) were calculated for the South Australian population from the Dental Care and Oral Health Study. RESULTS: Participants with lower educational attainment were 33% (Odds Ratio: 0.67, 95% CI 0.56-0.78) and 38% (Odds Ratio: 0.62, 95% CI 0.53-0.74), less likely than their counterparts with higher education to visit a dentist or to receive dental care in the last 12 months, respectively. Low education was associated with a 23% increase in odds of receiving emergency and treatment services (Odds Ratio: 1.23, 95% CI 1.05-1.43) compared to routine dental check-ups or examinations. CONCLUSION: Low education, regardless of oral health behaviours and status, reduces the odds of dental service utilization in terms of frequency of seeking dental care and time of last dental visit. There is more tendency towards receiving emergency and treatment services compared to routine dental check-ups or examinations in participants with lower educational attainment.

A Rare Odontogenic Cyst in an Uncommon Area: Case Report and Review of the Literature / Um cisto odontogênico raro em uma área incomum: Relato de caso e revisão da literatura

Abstract Objective Orthokeratinized odontogenic cyst is a rare developmental odontogenic cyst of the jaws. It is a less aggressive intraosseous cyst identified by an orthokeratinized epithelium. Case Report A 50-year-old male patient with the chief complaint of swelling in the anterior part of his face, and, intraorally, there was diffuse swelling in the palatal cortex. On panoramic radiography, there was a well-defined unilocular radiolucency on the right side of the maxilla and palatal cortical expansion, and thinning of the buccal and palatal cortexes was observed. The histopathological examination revealed a pathologic cyst that was lined by a thick orthokeratinized epithelium. Therefore, the diagnosis was orthokeratinized odontogenic cyst. Conclusion The orthokeratinized odontogenic cyst displays characteristic clinical, histopathological, and biological features that differ significantly from those of keratocystic odontogenic tumor (KCOT), but it has a better prognosis and lower recurrence rate. Thus, other radiolucent lesions of the jaws, including keratocystic odontogenic tumor (KCOT), must be considered in the differential diagnosis.

Resumo Objetivo O cisto odontogênico ortoceratinizado é um raro cisto odontogênico maxilar. É um cisto intraósseo menos agressivo, identificado por um epitélio ortoceratinizado. Relato de caso Um paciente do sexo masculino, de 50 anos de idade, com queixa principal de edema na parte anterior da face, e, intraoralmente, havia edema difuso no córtex palatal. Na radiografia panorâmica, havia uma radioluminescência unilocular bem definida no lado direito da maxila e expansão cortical palatina, e desbastamento dos córtex vestibular e palatino. O exame histopatológico revelou cisto patológico revestido por espesso epitélio ortoceratinizado. Logo, o dignóstico foi de cisto odontogênico ortoceratinizado. Conclusão O cisto odontogênico ortoceratinizado apresenta características clínicas, histopatológicas e biológicas que diferem significativamente das do tumor odontogênico ceratocístico (TOC), mas tem melhor prognóstico e menor taxa de recorrência. Portanto, outras lesões radiolúcidas dos maxilares, incluindo TOC, devem ser consideradas no diagnóstico diferencial.

Solitary intraosseous neurofibroma of the mandible: Report of an extremely rare histopathologic feature.

Neurofibroma (NF) is a benign tumor derived from the peripheral nerve sheath. Neurofibromas may present either as solitary lesions or as part of the generalized syndrome of neurofibromatosis or von Recklinghausen's disease of the skin. The intraosseous variant of NF is very rare. We report a case of a 32-year-old female who was diagnosed with a solitary intraosseous neurofibroma of the mandible. The present case is rare with respect to its unique histopathologic feature.
