The family of Elaine O'Hara has heard there is no cause of death for the childcare worker.
Speaking at the opening of the inquest into her death, coroner Dr Brian Farrell said the post mortem report by Deputy State Pathologist Dr Michael Curtis gave the cause of death as "undetermined".
Ms O'Hara, 36, from Belarmine Plaza in Stepaside, had been missing for more than a year when her partial remains were found by a hillwalker on Killakee mountain in Rathfarnham, on 13 September.
The remains were in a decomposed state.
The court heard that identification was carried out by forensic odontologist Dr Mary Clarke.
Dr Farrell said he received an extensive report from Dr Clarke and she is in no doubt that the remains are those of Ms O'Hara.
Detective Inspector Brian Duffy of Blackrock Garda Station requested copies of the post mortem and forensic odontology report.
The inquest was adjourned sine die - or without assigning a further date - until the outcome of criminal proceedings is known.
Ms O'Hara's father Frank O'Hara was present in court along with his daughter and son-in-law.
He told the coroner that his daughter was 36 when she went missing and asked what the date of death would be.
Dr Farrell said that death was pronounced on 14 September following the discovery of Ms O'Hara's remains.
The coroner said that he was unable to comment pending the outcome of criminal proceedings, but he extended "very deepest sympathy and condolences" to the family on behalf of the community.
