After 4 months we noticed internal resorption in the apical fragments of these teeth.
Some changes that may affect the tooth fragment such as pulp calcification, ankylosis, external and internal resorptions may be found in follow-up examinations (Andreasen & Andreasen 1994, Davidovich et al.
In the present study, three teeth in the ABS group and two teeth in the FC group showed internal resorption at 12 months follow-up.
The internal resorption begins at the junction of the pulp and dentine, and is at the expense of the dentine and so results in widening of the pulp chamber [Skillen, 1941; Browne, 1954; Muhler, 1957; Blackwood, 1958; Wooden and Kuftinee, 1974; Grundy et al., 1984; Brooks, 1988; Seddon et al., 1996; Seow et al., 1999 a and b; Nik and Rahman, 2003].
One of such conditions is internal resorption, which presents as an irregular defect in the root canal.
Poor prognosis can develop due to pulpal necrosis, PDL death can lead to internal resorption, ankylosis, replacement resorption and eventually to the loss of the tooth.
At 03 months in Group F displayed 28 cases (93.3%) were successful and 02 cases (6.7%) reported with failure due to intra radicular resorption while Group C presented with a success of 29 cases (96.7%) and a failure of only 01 case (3.3%) due to internal resorption as shown in Fig 1.
These studies used zinc oxide-eugenol or polycarboxylate cement over the amputated pulps, possibly confounding tissue changes as a previous histological study showed zinc oxide-eugenol directly contacting vital pulp caused persistent inflammation and internal resorption [Berger, 1965].
