Abstract
The aim of the present study was to compare the use of three cervical vertebral evaluation methods (Hassel-Farman, Baccetti et al., and Seedat-Forsberg) for determinating skeletal maturation stage in orthodontic patients. Twenty-three radiographs were randomly selected from a private orthodontic practice. Each radiograph was analyzed on three separate occasions by four evaluators (one radiologist and three orthodontists), who determined the skeletal maturation stage using the references established by each of the three methods. Intraevaluator and interevaluator comparisons were performed, and the degree of agreement was established using the weighted Kappa coefficient (95% CI). Good agreement (Kappa between 0.61 and 0.80) was observed between the determinations of most of the evaluators. The three methods demonstrated clinical applicability. However, the method proposed by Baccetti et al. achieved the best results, followed by the Hassel-Farman and the Seedat-Forsberg methods.

The study was based on identifying the skeletal maturation stage of the cervical vertebrae by four evaluators who were duly instructed in performing the evaluation using the three proposed methods
An adjustment was made to allow for the Hassel-Farman method having six cervical vertebral maturation stages (CVMSs) and the method proposed by Baccetti et al.[9] having five

Received for publication on Jun 07, 2010. Accepted for publication on Jul 07, 2010. The most frequently employed methods for determining skeletal maturation stage in orthodontics are the use of radiographs of the hand and wrist, the cervical vertebrae. A number of authors state that such methods are reliable and that they can be routinely employed in orthodontic treatment planning.[1,2,3,4,5,6,7]. The chief methods for determining skeletal maturation in orthodontic patients through the assessment of cervical vertebrae are those proposed by Hassel and Farman[8] (1995), Baccetti et al.[9] (2002), and Seedat and. These methods have been systematically employed in studies and clinical practice, the literature does not offer any consistent evidence regarding their advantages and disadvantages or the limitations of one method compared with another
