Pricing for Cementum Age Analysis

How to Estimate the Cost of your Order

The lab minimum charge is $75.

All clients will be charged $75 for their order, which covers complete processing for up to 4 teeth from regularly scheduled research/agency clients. Once the $75 threshold has been crossed, pricing is broken down by amount and specific services needed instead. Please see information below for details.

Standard Sections

Our standard microscope slide preparation has 2 tooth sections for 3 separate teeth mounted on a single slide. Suitable for most client purposes.


1-4 teeth………………….Lab minimum ($75)
5-29 teeth……………………..$9.95 per tooth
30-300 teeth………………….$4.75 per tooth
301-1000 teeth………………$3.90 per tooth
Over 1000 teeth…………….$3.35 per tooth

Research Sections

Research sections are for teeth that are either very small or of such unusual value to warrant the additional processing expense. Instead of the usual 2 sections per tooth, 6-8 are taken for maximum cementum exposure.

1-4 teeth…………………….Lab minimum ($75)
Over 4 teeth…………………….$9.95 per tooth

Cementum Age Analysis

The age of a specimen is determined by matching standardized analysis models with the characteristics of microscopic cementum annuli.

Analysis of adult teeth or inspection aging of juvenile teeth$1.75 per tooth
Analysis of certain species, including sea otters, river otters, mountain lions, seals, and brown bears$1.95 per tooth
Special Handling of Specimen Envelopes or Inventory List

Envelopes or master lists that are not submitted in an immediately usable order or format will accrue the following charges.
Please note that kill date must be known for all species for the period between February 1 and August 31.

Sort and collate specimen envelopes$0.30 per tooth
Number tooth envelopes as specified by biologist$0.30 per tooth
Prepare or add data to master inventory list$0.30 per tooth
Tooth Extraction and Cleaning

To protect the integrity of lab equipment, overly dirty or large teeth will be subject to additional cleaning charges.

Cleaning dirty teeth$0.55 per tooth
Trimming large teeth down to size$0.55 per tooth
Extracting teeth from jaws or bone$0.95 per tooth

Additional Services

Rush Services

May be available based on lab schedule, quantity, and species. No quantity discounts are offered for rush orders, and all rush orders must be accompanied by an electronic master list. Contact the lab for pricing and availability.

Legal Evidence

A charge of $75 is applied for 1-3 teeth, and legal orders are processed within 30 days. Duplicates are kept at the lab for each case. For large numbers of teeth to be processed as legal evidence, inquire for price and turnaround time.

Reproductive History Reconstruction

An additional $1.95 per animal is charged for female black bears with reproductive history reconstructions. For those females with cementum evidence suggesting cub rearing, the reconstruction is an essential but time consuming part of age analysis. Gender must be known for accurate age analysis.
