SCN9A channelopathy associated autosomal recessive Congenital Indifference to Pain. A case report

BACKGROUND

Congenital Indifference to Pain (CIP) is a rare condition that inhibits the ability of patients to perceive physical pain but otherwise keeps normal sensory modalities. The condition has been mapped to an autosomal recessive trait to chromosome 2q 24.3 with mutations on the SCN9A gene.

CASE REPORT

A 2 year old Caucasian female presented with CIP. Bite injuries, tongue wounds and unaccounted dental trauma episodes were frequently reported. Preventive instructions and possible treatment modalities were discussed with the parents.

CONCLUSION

The cornerstone of treating CIP patients is an extensive preventive approach alongside regular oral examination at home by parents as well as routine recall appointments with dentists.

Endodontic treatment of trauma-induced necrotic immature teeth using a tricalcium silicate-based bioactive cement. A report of 3 cases with 24-month follow-up

BACKGROUND

Pulp necrosis is the second most common complication after traumatic dental injuries and occurs mostly within the first 6-24 months of follow-up period, depending on the type of dental trauma.

CASE REPORT

Three cases with endodontic treatment scenarios of trauma-induced necrosis in immature permanent anterior teeth. All cases were treated by full canal obturation with Biodentine (Septodont, Saint Maur des Fosses, France) and documented for a follow-up period of 24 months.

CONCLUSION

Copious irrigation of the root canal, minimal mechanical preparation, use of calcium hydroxide for a short period of time and complete obturation of these immature teeth with a bioactive cement with superior mechanical properties such as Biodentine were the prominent reasons attributed to the success of these three cases.
