Skeletal and dental characteristics in subjects with ankyloglossia.

Srinivasan B, Chitharanjan AB - Prog Orthod (2013)

Bottom Line: Majority of group 1 subjects belonged to class I skeletal base followed by class II and class III skeletal bases.The mean maxillary and mandibular intercanine widths and maxillary intermolar width were statistically significant in independent t test (P<0.01) and reduced in group 1.Subjects with ankyloglossia had reduced maxillary and mandibular intercanine widths and reduced maxillary intermolar width.

ABSTRACT

Background: The role of ankyloglossia in etiology of malocclusion is not much discussed over the years. The aim of the present study was to assess the skeletal and dental characteristics in subjects with ankyloglossia.

Methods: Fifty-seven subjects diagnosed with ankyloglossia (group 1) were compared with 60 subjects (group 2) without ankyloglossia, who had class I skeletal base. Ankyloglossia was diagnosed and graded (mild, moderate, severe and very severe) using Kortlow's method. SNA, SNB, ANB, Go-Gn-SN angle, FMA, maxillary and mandibular intercanine widths and intermolar widths, tooth size-arch length discrepancy in maxillary and mandibular arches and overbite were measured. Independent t test was used to compare the mean parameters between the two groups. Analysis of variance and Tukey honestly significant difference were used to compare mean parameters among various grades of ankyloglossia.

Results: Majority of group 1 subjects belonged to class I skeletal base followed by class II and class III skeletal bases. Moderate ankyloglossia was most common in group 1. The mean maxillary and mandibular intercanine widths and maxillary intermolar width were statistically significant in independent t test (P<0.01) and reduced in group 1. In ANOVA followed by Tukey HS, the Go-Gn-SN angle and overbite were statistically significant among different grades of ankyloglossia (P<0.05).

Conclusions: Subjects with ankyloglossia had reduced maxillary and mandibular intercanine widths and reduced maxillary intermolar width. The mandibular plane angle and overbite were altered with severity of ankyloglossia.

Fig2: Measurement of ankyloglossia with digital calliper.

Mentions: The measurement of ankyloglossia was based on the classification and grading system given by [10]. It was done using a digital vernier calliper which could make a minimum measurement of 0.01 mm. The distance between the tip of the tongue and the point of attachment of the lingual frenum was measured in millimetres (Figure 2). Clinically acceptable normal range for free tongue is 16 mm. The various grades of ankyloglossia are as follows:Figure 2
