Main Objective: To find out the impacts of free markets on public health using skin bleaching among the women living in Zimbabwe as a case study. Materials and methods: The study was designed as a case study which used a combined methodology facilitated by a cross sectional online survey among 270 women living in Zimbabwe and key informant intervie...

... the late erupting teeth are the ones usually associated with cystic formation therefore may account for the dentigerous having a higher frequency posteriorly. Based on these observations it can be hypothesized that a cyst presenting in the anterior maxilla is most likely a radicular cyst and a cyst presenting in the posterior mandibular region is most likely a dentigerous cyst or an OKC (Figure 2). In the posterior mandibular region a dentigerous cyst is considered first because it is more common than an OKC. ...

... [2] Various classifications of orofacial cysts could be based on the organs involved (odontogenic, salivary), presence or absence of epithelial lining (true cysts and pseudocysts), etiology (inflammatory and developmental), or site (soft tissue or intraosseous). [2,5] Among all orofacial biopsies, orofacial cysts have a prevalence as low as 5.5% in Zaria, Northwest Nigeria, [4] through 9.6% in Ghana, [9] and as high as 13.2% in ...
... [1,3] Most of the orofacial cysts are believed to arise from the activated proliferation of odontogenic epithelial rests of Malassez (Hertwig epithelial root sheath), of serres, of dental lamina, and reduced enamel epithelium. [2,4,5] The origin of other orofacial cysts is attributed to the basal cells of oral epithelium, [6] salivary duct trauma Zimbabwe.

A BSTRACT
Background
Orofacial cysts are pathologic cavities that could be symptomatic and may cause facial disfigurement. The only epidemiologic report of such lesions in Southeast Nigeria studied jaw cysts from 1987 to 1996. New studies reflecting recent research findings and classifications on the subject in Southeast Nigeria are lacking.
Aim
To determine the prevalence and distribution of orofacial cysts in a tertiary hospital in Enugu, Southeast Nigeria.
Methods
A 10-year retrospective study of patients with orofacial cysts diagnosed by histology was carried out.
Results
Orofacial cysts constitute 9.5% (85) of 897 orofacial lesions identified. The male-to-female gender ratio was 1.2:1. The mean age (± standard deviation) at the onset of the cystic lesion was 28.58 (±16.98) years. Developmental odontogenic cysts 52.9% (45) and salivary cysts 18.8% (16) were the most common group of orofacial cysts. The most prevalent orofacial cysts were odontogenic keratocysts at 25.9% (22), mucoceles 16.5% (14), and dentigerous cysts 14.1% (12). Straw-colored aspirates 34.8% (16) and dark brown aspirates 28.3% (13) were the predominant cystic contents. The mandible 45.9% (39) and maxilla 27.1% (23) were the commonest sites for orofacial cysts, while the lip 9.4% (8) was the most frequent soft tissue site. A significant association exists between anatomical site and cyst type at a 95% confidence interval with P = 0.000, X ² = 247.17. Unilocular radiolucency 62.5% (20) and multilocular radiolucency 34.4% (11) were the most common radiographic features.
Conclusion
Developmental odontogenic cysts particularly odontogenic keratocysts were most prevalent while mucocele was the most common soft tissue cyst.
A BSTRACT
Background
Odontogenic cysts (OCs) are commonly encountered lesions affecting the human jaws having special clinical and radiographic features depending on cyst type. The aim of this study was to determine the prevalence of odontogenic jaw cysts in a Libyan population in Benghazi and to compare these data with previously published reports from Libyan and other geographic areas.
Materials and Methods
This is a descriptive study where screening of 2189 biopsies (retrieved from the archives of The Department of Oral Pathology/University of Benghazi, Libya) was performed for the sake of recognizing the three cysts chosen for the purpose of this study.
Results
Out of the screened lesions, 276 cases (12.6%) were diagnosed as odontogenic cysts in the period from 2006 to 2019. Of those, 67.39% were inflammatory and 32.61% were developmental in nature. Radicular cysts (60.5%) were the most frequent cysts followed by dentigerous cysts (14.8%) and keratocysts (14.5%). The mean ages of the patients were 32.3, 29.7, and 33.2 years, respectively. Occurrence of the cysts was noticed more in the maxilla than in the mandible (1.3:1). The overall male-to-female ratio was 1.1:1.
Conclusions
The prevalence of odontogenic cysts was similar to that reported in a previous study in Libya and other countries irrespective to WHO (2017) classification of odontogenic cysts.
