Review on Mandibular Muscle Kinematics

“…Among the included publications, five of them (27.74%) had private funding [ 48 , 53 , 54 , 56 , 57 ], one (4.34%) obtained mixed funding [ 50 ] and the remaining 17 (65.22%) did not achieve a grant [ 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 49 , 51 , 55 , 58 , 59 , 60 ].…”

“…Most of the selected articles’ subjects were under-aged [ 39 , 42 , 43 , 45 , 46 , 47 , 50 , 53 , 56 , 57 , 60 ], and six publications included adults [ 39 , 40 , 48 , 51 , 52 , 54 , 59 ]. Only two research studies handled wide age ranges, basing their studies on children and adults [ 44 , 58 ], while four studies did not specify the sample [ 38 , 49 , 52 , 55 ]. The lowest sample size is one [ 48 , 55 ] and the highest 39 [ 58 ].…”

The lowest sample size is one [ 48 , 55 ] and the highest 39 [ 58 ]. The average sample size on the series of studies is 16.69.…”

“…The minimum age is three years old and the maximum is 70 years old ( Figure 2 ). Of the total sample from all the studies registered, 293 were healthy individuals [ 38 , 39 , 40 , 41 , 42 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 52 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ] whereas there were only 58 subjects with speech disorders [ 43 , 56 , 57 , 60 ], 38 subjects were patients with cerebral palsy [ 45 , 46 , 47 , 50 ], one had previously been submitted to be studied for facial surgery with a muscle transplant [ 38 ], and 30 presented facial bone reconstruction with fibula graft or iliac crest [ 51 ].…”

“…Different topics were studied, all of them were related to the stomatognathic system in a direct or indirect way, which remains the most studied topic (43.48%) the speech properties, especially pronunciation [ 42 , 43 , 45 , 46 , 47 , 50 , 52 , 56 , 57 , 60 ]. Dento-oro-facial level changes that influence posture and body movement [ 39 , 40 , 41 , 44 , 51 ] were also a reason for study (21.74%), as well as facial muscle analysis (17.39%) [ 38 , 49 , 53 , 54 ], mandibular dynamics during chewing (8.695%) [ 48 , 59 ] and mandibular kinematics in laterality and protrusion movements (8.695%) [ 55 , 58 ]. The selected research studies that were published in different journals and themes can be seen in Table 3 .…”
