Dear Dr Chris Alston,
If age determination by dental x-ray method has humongous uncertainties, I believe that the "practice" is not justified even when the doses are very small.In the case of hand x-ray method, the effective dose and the dose to the hand are small.In the case of dental x-ray one has to consider dose to other tissues such as thyroid,brain, bone marrow in the skull and also eye; as eye lens also is now considered like other sensitive organs
Any comments?
While I was reviewing the topic (dental radiograph for age determination), I came across a very useful document: 

Further I received some update one of the co authors of the above report Dr Tim Cole

If you ask me (and you didn't) it sounds like an extremely low risk/benefit
ratio (per the ICRP's mandate for the justifiability of a human radiation
exposure), what?

Dear Dr. Clayton,
You are correct.Currently, a non govermental organization (NGO) in
collaboration with a few dental colleges is involved in issuing birth
certificates to children (who do not have any birth certificates) on the
basis of dental images. Certainly this cannot be compared as a medical
study (with diagnostic or therapeutic benefits). In this particular
instance there are other ethical issues as well. I am including a news item
on the project which will give you an idea about the project
100 orphans get birth certificates after age estimation studies

hundred children from orphanages are all set to get their birth
certificates,an important document for government work. In a collaborative
charity projectby Terna Dental College, Mumbai, and Date of Birth
Foundation, Hong Kong, thecollege and the foundation have signed an MoU to
conduct dental age research.
"Inthe first phase of the project, 100 children without birth documents
wereidentified from NaviMumbai region andbrought to the dental college,
where dental x-rays were obtained and ageestimation was done. Hence, age
certificates will be issued to these children;now, these kids have a date
to remember and celebrate in their lives,"said Dr Shishir Singh, dean of
the college.
Birth registrationis a fundamental human right. The United Nations
Convention on the Rights ofthe Child (UNCRC) article 7 states that a child
has to be registeredimmediately after birth; this applies to all countries
that are signatorieswith the United Nations.
"Illegitimatechildren, children in orphanages, children born at home do not
have birthcertificates. Through this procedure, we will be able to give
them agecertificates," said Singh.
In India,registration of birth is mandatory, according to Registration of
Births andDeaths Act, 1969. As of 2012, Unicef reports that only 41% of
births areregistered in India. It further projects that out of the 26
million birth
​ ​
severy year, around 10 million go unregistered.
A birth certificate serves
​ ​
as an identity document that confirms the existence of a child. The absence
ofbirth documents questions the existence of millions of children around
theworld and fails to guard them against age-related crimes and abuses. A
birthcertificate serves as a baseline document for getting admission to
school,obtaining driving licence, passport, claim of property, and seek
insurance andsocial security benefits. The lack of birth identity documents
can lead tofalsified testimonials of age when children want to enrol in
school, work,appear in national competitive exams and participate in age
categorised sportsand games tournaments.
AS per US guidelines (Federal or State) is this practice "justified" ICRP
