a Student t-test; b chi-square test; av.—average; SD—standard deviation; Q1—lower quartile; Q3—upper quartile; AJS—anterior joint space; PJS—posterior joint space; SJS—superior joint space; MJS—medial joint space, TMJ—temporomandibular joint, Δ—difference between the values after and before the treatment (i.e., ΔConRat = ConRat after treatment − ConRat before treatment).
