Abstract – Background: Non-setting calcium hydroxide (Ultracal XS®)
is recommended by the International Association of Dental Traumatology
as the initial medicament following avulsion and replantation for mature
teeth. There is experimental evidence to suggest Ledermix®,
placed as an alternative inter-visit dressing may improve periodontal
healing. Aim: This study investigated, using a multi-centre randomized
controlled trial, the effect of two root canal medicaments, Ledermix® and Ultracal XS®,
on periodontal healing of avulsed and replanted teeth. Material and
methods: Children were recruited if they fulfilled all inclusion
criteria. Treatment followed a standardized protocol. Assessment of
periodontal healing or ankylosis was made clinically and
radiographically by an experienced, ‘blinded’, clinician at 12 months.
Results: Over 200 patients were assessed for eligibility at five
centres. Twenty-nine patients were eligible for inclusion. Final
analysis involved 22 patients with 27 teeth. Ankylosis was detected in
four of the 12 teeth in the Ledermix® group and nine of 15 in the Ultracal XS®
group. No significant difference between medicaments was found in the
proportion of teeth or patients showing periodontal healing.
Discussion: There was no significant difference in periodontal healing
between the two medicaments at either a tooth or patient level. The
numbers recruited fell short of an estimated power calculation. For
patients meeting the inclusion criteria and completing the trial,
periodontal healing was seen in 52% of teeth at the 12-month assessment
between both groups. The only factor found to significantly influence
the periodontal outcome was dry time.
