Abstract
Purpose: This research aimed to investigate the relative frequency of odontogenic tumours (OT) and selected odontogenic cysts in a single oral pathology center in New Zealand from 2008 to 2023.
Methods: Histopathological records from the Oral Pathology Centre, University of Otago (2008-2023) were examined to identify OT. Odontogenic keratocyst (OKC) and calcifying odontogenic cyst (COC), previously classified as OT were also included. Patient demographics, clinical details and histopathologic diagnoses were recorded. Data were analyzed using SPSS.
Results: Of the 34,225 biopsies over the 15-year period, 1.8% were identified as OTs, COC and OKCs and accounted for 47%, 1.5% and 51.5% respectively. The most prevalent OT types were odontoma (43.7%), ameloblastoma (27%) and cemento-ossifying fibroma (7.5%). Malignant OT, ameloblastic carcinoma, constituted 1.4% of OT. The average age at diagnosis for OKC, COC and OT patients were 48.2 ± 20.9, 33.7 ± 23.3 and 28.9 ± 19.3 years. Overall, male and mandibular site predilections were observed. Recurrence of OKC and ameloblastoma occurred in 15.2% and 13.7% of patients. The time for recurrence for OKC and Ameloblastoma were 61.7 ± 56.5 months and 122 ± 152 months respectively.
Conclusion: The demographic features and range of OT, COC and OKC in New Zealand align with those of other western countries. The study also confirms need for long term follow up for patient with OKC and ameloblastoma.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
