Replantation of three avulsed permanent incisors with complicated crown fractures

Abstract

The case describes a 3-year follow-up of the treatment of three avulsed maxillary incisors with complicated crown fractures. The teeth were replanted after an extra-oral time of 90 min (extra-oral dry time 6 min). After root canal treatment, the fractured maxillary incisors were restored with a layered hybrid composite material to re-establish aesthetics and function. Follow-up visits showed signs of replacement resorption affecting the maxillary central incisors but only minor signs of root resorption on the maxillary right lateral incisor. These findings were supported by digital volume tomography, which was performed 18 and 36 months post-trauma in order to assess extent, severity and progression of root resorption more accurately. *Healing of avulsed teeth depends on the degree of periodontal ligament (PDL) damage. *Digital volume tomography might improve diagnostics of root resorption.

Association of tobacco use and periapical pathosis – a systematic review

“…1989, Eriksen & Bjertness 1991, Huumonen & Ørstavik 2002). Recently, Cone‐Beam Computed Tomography (CBCT) has been introduced to endodontic imaging (Walter et al. 2008, de Paula‐Silva et al.…”

“…Whilst cross-sectional studies may demonstrate differences in prevalence of periapical pathosis, longitudinal studies may show differences between the smoking groups regarding the incidence, that is, the development of new periapical pathosis within a time frame. These are very different concepts and can indicate if it is the healing of apical periodontitis that might be delayed amongst smokers (Silverstein 1992, Walter et al 2008 or if they are more prone to develop apical periodontitis. The latter is probably not the case, because two of three longitudinal studies do not show a difference between the smokers and non-smokers.…”

“…The major drawbacks in panoramics are (i) overlaps of teeth or narrow spaces between teeth (Persson et al 2003); (ii) accuracy in evaluating periapical conditions, with the exception of mandibular second and third molars (Ridao-Sacie et al 2007); and (iii) underestimation of periapical pathosis (Rohlin et al 1989, Eriksen & Bjertness 1991, Huumonen & Ørstavik 2002. Recently, Cone-Beam Computed Tomography (CBCT) has been introduced to endodontic imaging (Walter et al 2008, de Paula-Silva et al 2009, Liang et al 2011. The accuracy of CBCT was compared with conventional radiographs.…”
