| The aim of this study was to analyze the relationship among the point of greatest depression on the root trifurcation floor and the furcation openings of the maxillary second molars. Sixty human extracted upper permanent second molars were analyzed and the furcation area were measured using a vertical calliper, and the values regarding the point of deepest depression were recorded. The results showed that the deepest depression in the trifurcation floor of the roots is centrally situated in 11.7% of the cases, whereas 88.3% involve mesial-buccal and distal-buccal roots. The distal furcation (F3) had the largest distance from the point of deepest depression in the trifurcation floor (A), followed by the buccal (F1) and mesial (F2) furcations when point A... |

| First lower premolars are the teeth with greater variations following third molars. Fifty four first premolars extracted by orthodontic indication from patients in Temuco, Chile, were studied and classified by age, sex and maxillar and mandible location. The following parameters were measured: vestibular-palatine diameter (VP), mesiodistal (MD) diameter, coronary height (C-O), root length and total length. The data were statistically analyzed and tabulated. The results exhibited that first upper premolars showed higher values in the VP diameter and root length compared with the lower, noting significant differences. Further, male sex showed higher values on most measures compared with females, except in root length. Finally a difference in root length was... |
