Overall, facultative heterofermentatives (homofermentative bacteria that can alter their metabolism to resemble heterofermentation
under certain conditions) were present in higher numbers in the periodontitis patients than in the healthy patients, while the obligate homofermentatives (those that must metabolize using homofermentation, with a limited by-product) were relatively low.
This indicated that the fermentation pattern was changed from homofermentation to heterofermentation
and is in agreement with other studies as reported by Shao et al.
