THECs were performed using a Malassez hemocytometer after a 1:200 dilution with an eosinophil dilution liquid containing phloxine B.
These cysts have an epithelial lining that derives from the tooth-forming organ epithelia: the so-called glands of Serres (rests of the dental lamina), the rests of Malassez (rests of the root sheath of Hertwig), and the reduced enamel epithelium (remnants of the enamel organ after dental crown formation).
In the case of molars, in advanced developmental stages the apical loop leaves the external and internal epithelium, the so-called Hertwig epithelial root sheath, which is a structure necessary for the root to achieve the appropriate length; it is later divided and replaced by cementoblast precursors, called epithelial cell rests of Malassez [37].
The etiology and histogenesis of BOC remains uncertain, and several proposed possible sources such as epithelial cell rests of Malassez and reduced enamel epithelium have been rejected as the possible sources (3).
3 It is an inflammatory cyst, which results from proliferation of epithelial rest of Malassez because of inflammation.
Cell suspensions were kept on ice to reduce hemocyte aggregation, and cell concentrations were evaluated using a Malassez hemocytometer.
Controversies Regarding Histogenesis: The source of origin of lateral periodontal cysts remains controversial, with extensive debate in the literature over whether the lesion derives from the dental lamina, reduced enamel epithelium, or rests of Malassez.

Su etiologia aun es incierta, sin embargo, se atribuye a la hiperactividad de la lamina dentaria (epitelio embrionario); donde a partir de los restos epiteliales de Malassez, se pueden producir yemas dentarias en exceso.
En la ultima decada la taxonomia del genero Malassezia ha sufrido una profunda restructuracion gracias a la aparicion de nuevas tecnicas moleculares, alprincipio solo se conocian 3 especies, Malassezia furfur Robin Malassez, Baillon 1889, Malassezia pachydermatis Weid Mondolgel 1935 y Malassezia simpodyalis Simmons y Gueho (1990), luego basandose en caracteristicas morfologicas, inmunologicas, fisiologicas, ultraestructurales y moleculares en 1996, Gueho y colaboradores descubrieron otras especies de Malassezia, globosa, obtusa, slooffiae, restricta, japonica, dermatis, equi y nana.
