The preforation was cleaned and repaired with MTA. A resorbable collagen matrix was used to prevent extrusion of the MTA into defect. The root canals were negotiated to their full length, chemo-mechanically debrided and filled.
At one year review there is no apical radiolucency and there has been significant reduction in the size of the radiolucency around the perforation repair.

Careful negotiation of the mesio buccal root with small k files to establish a glide path
A curved root
This upper left 1st molar was referred due to the extreme curvature of the mesio-buccal root. After ensuring good straight-line access to the root caanls Martin established a glide path with hand files before, carefully, preparing the root canals with reciprocating files. After thorough chemo-mechanical debridement with EDTA and sodium hypochlorite the tooth was obturated with a warm vertical technique.
A perforated molar
The lower right 1st molar had been root treated some years prior to the patient seeing Martin. Clinically there was an isolated deep pocket buccally. Radiograophic investigation revealed a poor root filling and a perforation in the furcation region. Endodontic retreatment of the tooth was carried out over two visits and the perforation reapired with MTA.
At a one year review the tooth remains asymptomatic, the pocket has resolved and there has been significant bony infill in the furcation region.
Some of Martin's cases

After accessing the root canal system it could be seen that 3 canals had been located and filled.
A missed canal
The upper left 1st molar had previously been root-filled but had persisting symptoms. Radiographic examination revealed a short and thin root filling and apical radiolcuencies. Orthograde retreatment was carried out over two visits. The existing root filling material was removed with files and solvents. A second canal in the mesio-buccal root was located using ultrasonic instruments. All four root canals were prepared with reciprocating instruments and chemo-mechanically debrided with EDTA and sodium hypochlorite. At the second visit the tooth was obturated using a warm vertical technique.
A fractured instrument
The lower left 2nd premolar fractured and required a post-crown to restore it. Unfortunately a previous dentist had attempted a root filling and fractured a small hand file in the root canal. Martin removed the instrument using a Masseran kit and following root treatment placed a fibre post and composite core ready for restoration with a crown
This patient's upper left central incisor had been root treated and retreated but, unfortunately, the apical infection persisted. The tooth was, therefore, treated via a surgical approach. Using modern techniques the root end was accesed and prepared using ultrasonic instruments under an operating micrscope and the root end cavity sealed with MTA. At six month review the infection had resolved and radiographic investigation showed normal, health periapical tissues.
