AIM To compare the efficacy of sodium hypochlorite (NaOCl) used at different concentrations and working times for removing necrotic periodontal ligament (PDL) from delayed replanted teeth and to observe the effects of NaOCl on surface structure and microhardness of cementum. METHODOLOGY A total of 88 healthy premolars with a single root extracted for orthodontic purposes were selected and kept dry at room temperature for 1 h. The teeth were divided into 11 groups: group 1 (control): roots…

Compositional and microhardness findings in tooth affected by X-linked hypophosphatemic rickets
TLDR
Compositional and structural deficiencies were observed in deciduous tooth affected by XLHR and it was observed the absence of hydroxyapatite in the interglobular dentin by using Raman spectroscopy analysis.
Manufacture and preliminary evaluation of acellular tooth roots as allografts for alveolar ridge augmentation.
TLDR
It is demonstrated that the acellular tooth root (ATR) could be used in alveolar ridge augmentation as a kind of new tooth-derived bone graft material.
A 14 year old boy with reimplantation of avulsed maxillary central incisors
TLDR
A 14 year old boy, came to the Department with the complaint of accidental missing of upper two central incisor teeth, and came 2 hours after the accident with the missing teeth immersed into 0.9% sodium chloride solution.

Mechanical removal of necrotic periodontal ligament by either Robinson bristle brush with pumice or scalpel blade. Histomorphometric analysis and scanning electron microscopy.
TLDR
Analytical analyses of the results showed that the RBP technique was significantly more effective than the SBS technique for removal of the periodontal ligament remnants adhered to root surface, and both techniques preserved the cementum layer.
DELAYED TOOTH REPLANTATION AFTER ROOT SURFACE TREATMENT WITH SODIUM HYPOCHLORITE AND SODIUM FLUORIDE: HISTOMORPHOMETRIC ANALYSIS IN RATS
TLDR
All groups were affected by root resorption but the treatment performed in group III was the least effective for its control, showing that root structure and cementum extension were more affected by Resorption in groupIII (p<0.05).
Effect of the treatment of root surface-adhered necrotic periodontal ligament with propolis or fluoride in delayed rat tooth replantation
TLDR
Under the tested conditions, the application of fluoride or propolis on root surface-adhered necrotic periodontal ligament did not favor the healing process in delayed tooth replantation.
Evaluation of the effect of endodontic irrigation solutions on the microhardness and the roughness of root canal dentin.
TLDR
Although there are many other factors for irrigation solution preference, 0.2% chlorhexidine gluconate seems to be an appropriate endodontic irrigation solutions because of its harmless effect on the microhardness and roughness of root canal dentin.
Evaluation of the topical effect of alendronate on the root surface of extracted and replanted teeth. Microscopic analysis on rats' teeth.
TLDR
Sodium alendronate was able to reduce the incidence of radicular resorption, but not of dental ankylosis, and no significant differences were observed regarding variations in the extra-alveolar periods among the groups.
The role of the necrotic periodontal membrane in cementum resorption and ankylosis.
TLDR
Examination of resorption and ankylosis patterns following replantation of teeth with chemically denuded root surfaces revealed that bone replacing the periodontal membrane space grew from the alveolus towards the cementum, to which it appeared unable to fuse due to the absence of significant resor adaptation.
Effect of stannous fluoride and tetracycline on repair after delayed replantation of root-planed teeth in dogs.
TLDR
Root surface treatment with SnF2 followed by tetracycline resulted in complete absence of inflammatory resorption and ankylosis in this short-term experiment, confirming that the frequency of adverse healing reactions after delayed replantation of teeth from which nonvital soft tissue remnants have been removed can be reduced by demineralizing the root surface and preventing mechanical trauma to theRoot surface in the postoperative period.
Use of vitamin C in delayed tooth replantation.
TLDR
This study evaluated microscopically the effects of root surface treatment with three different solutions in delayed rat teeth replantation, showing more areas of ankylosis and replacement Resorption than areas of inflammatory resorption.
The effect of citric acid treatment on periodontal healing after replantation of permanent teeth.
TLDR
The results indicated that surface demineralization had an initial positive effect, but later led to impaired healing.
Effect of stannous fluoride and tetracycline on periodontal repair after delayed tooth replantation in dogs.
TLDR
The findings indicate that reducing the strength of the SnF2 solution from 1% to 0.1% may result in less persistent inflammation, at the cost, however, of less complete prevention of inflammatory resorption and ankylosis.
