According to endodontic literature, two radiographic techniques have been employed to capture an image of the tooth and its root onto a periapical film namely the paralleling and bisecting angle techniques.
The purpose of this cross-sectional study was to compare the efficacies and errors of Paralleling tech- nique (PT) and Bisecting angle technique (BAT) when used for endodontic working length determination.
In Group A, with paralleling technique (PT) (n=60) the retake (unacceptable radiographs) was 10 Percent (n=6), while 18 out of 60 radiographs (30 Percent) were repeated when bisecting angle technique (BAT) was employed, as shown in Table 1.

TABLE 2: COMPARISON OF OUTCOME (ACCEPTABLE V/S UNACCEPTABLE) IN PARALLELING (PT) AND BISECTING ANGLE TECHNIQUES (BAT) IN MANDIBLE GROUP (B) (N = 120)
As mentioned before, Bisecting K-Means terminates when a stopping criterion is met.
In the exhaustive version of the algorithm used in this paper, the process of selecting and bisecting leaf clusters continues until leaf clusters are singletons (i.
The run time of Bisecting Incremental K-Means method is O([Nlog.
The algorithm involves time consuming processes such as (a) Bisecting of a leaf cluster and (b) Computing the BIC values of a leaf cluster and of its descendant nodes which takes time linear to the number of documents in a cluster.
On March 23, she and husband Lee, a plumber and certified building inspector, were driving home from their cabin in Lake Isabella along State Highway 184 near the town of Arvin, an agricultural stretch of road bisecting
grape, cotton and onion fields.
A secondary ramp penetrates the building at first floor level, bisecting
the inner courtyard.
In another box piece, also Untitled, 1999, eight decals depicting a generic boy and dog face off across a closed hallway that circumscribes the sculpture, serving as portals to the conflicted nostalgia at the heart of the work, while a blank, open-ended hallway bisecting
the box's interior conveys a faint, disjunctive loneliness.
