The association of endodontic prognostic factors with the presence of periapical lesion, its volume, and bone characteristics in endodontically treated molars: a cross-sectional study

Table 2 The association between tooth type and two dependent variables

Tooth type	PL status		P	Mean PL volume (mm³)	p
	Present, n (%)	Absent, n (%)	0.021*		0.006*
Maxillary first molar	74 (61.1%)	47 (38.9%)		24.23
Mandibular first molar	25 (43.1%)	33 (56.9%)		13.69
Maxillary second molar	25 (47.1%)	28 (52.9%)		19.95
Mandibular second molar	15 (30%)	35 (70%)		9.68

PL: periapical lesion, *: statistically significant level. Chi-square and independent samples T-test were employed to reveal the association between the tooth type and the PL prevalence, and between the tooth type and the PL volume, respectively
