Clinical and Radiographic Characteristics as Predictive Factors of Swelling and Trismus after Mandibular Third Molar Surgery: A Longitudinal Approach

Table 1

Variables included in the model (fixed component).

Code	Variable	Units
Gender	Gender of the patient	F (female)
		M (male)
Baseline	Basal value (time 0)	mm
Age	Age of the patient	Years
BMI	Body mass index	kg/m^2
TQX	Surgical elapsed time	Minutes
Total intake	Total consumption of analgesic intake in 72 hours	Number of tablets
R2M	Relationship of the third molar to second molar	0: Crown directed at or above the equator second molar
		1: Crown directed below the equator second molar
		2: Crown/roots directed to the middle of the second molar
		3: Crown/roots directed to the apical third of the second molar
RRM	Relation to the mandibular ramus	0: Sufficient space in the dental arch
		1: Partially impacted in the ramus
		2: Completely impacted in the ramus
		3: Completely impacted in the ramus in distoangular position
RRA	Relation to the adjacent alveolar crest (from the uppermost point of the tooth)	0: Completely erupted
		1: Partially impacted, but widest part of the crown (equator) is above the bone
		2: Partially impacted, but widest part of the crown (equator) is below the bone
		3: Completely impacted
RRB	Relation to the lingual and buccal walls	0: Closer to buccal wall
		1: In the middle between lingual and buccal walls
		2: Closer to lingual wall
		3: Closer to lingual wall, when the tooth is partially/completely impacted
