Use of lingual frenum in determining the original vertical position of mandibular anterior teeth.

STATEMENT OF PROBLEM: There is no accurate method for determining the correct vertical dimension of occlusion in edentulous patients. Preextraction diagnostic casts may facilitate determination of vertical dimension of occlusion. In the maxilla, the incisive papilla is a stable anatomic landmark and can be used as a guide to determine the vertical relation of the edentulous patient. Unfortunately, the mandible is devoid of such a stable anatomic landmark. PURPOSE: This study evaluated the reliability of measurement of the distance between the anterior attachment of the lingual frenum and the incisal edges of the mandibular incisors, on casts, to be used as a preextraction record for determining the vertical position of the mandibular incisors in complete denture patients. MATERIAL AND METHODS: Eighteen dentate subjects (9 men, 9 women; 21-28 years; mean age 23 years) were selected. Four mandibular casts were made from irreversible hydrocolloid impression material in plastic stock trays for each subject. All subjects were instructed to elevate the tongue while the impressions were made. The vertical distance between the anterior attachment of the lingual frenum and incisal edges of mandibular central incisors was measured on the casts. Means and standard deviations of the 4 measurements were calculated and statistically analyzed. RESULTS: The mean standard deviation of the distance between the anterior attachment of the lingual frenum and incisal edges of mandibular central incisors among the subjects was 0.1326 mm (coefficient of variation 1.292%). The distance between the anterior attachment of the lingual frenum and incisal edges of mandibular incisors was relatively stable when the frenum was recorded during function. CONCLUSION: The distance between the anterior attachment of the lingual frenum and incisal edges of the mandibular central incisors can be used on preextraction diagnostic casts as a preextraction record for determining the original vertical position of the mandibular anterior teeth.

A study of pathology associated with short lingual frenum.

Ankyloglossia is a developmental anomaly of the tongue characterized by a short, thick, lingual frenum resulting in limitation of tongue movement. The frenum is attached to the tip of the tongue in varying degrees. This study evaluates short lingual frenum and other associated pathologies (dentofacial anomalies and lingual dysglossia) and investigates whether ankyloglossia is related to speech problems. A thorough intraoral examination was carried out using the WHO regulations for dentofacial anomalies and occlusion problems and a new scale of lingual mobility. This article also discusses the difficulty in diagnosing this condition and finally following to the results of our study, describes the indications for nonsurgical and surgical treatment of this anomaly.

Rapp-Hodgkin syndrome with palmoplantar keratoderma, glossy tongue, congenital absence of lingual frenum and of sublingual caruncles: newly recognized findings.

We report on a boy with Rapp-Hodgkin syndrome (RHS) or Rapp-Hodgkin ectodermal dysplasia. He had sparse, wiry, slow growing and uncombable hair, but no pili torti or pili canaliculi characteristic of RHS. He also had sparse eyelashes and eyebrows, and obstructed lacrimal puncta and epiphora. Bilateral bony external auditory canal stenosis led to hearing loss. The mouth was small with repaired bilateral cleft lip and palate. Oral manifestations included hypodontia, microdontia, unerupted mandibular premolars with well formed roots, large dental pulp spaces, enamel hypoplasia, multiple caries, glossy tongue, and congenital absence of lingual frenum and of sublingual caruncles including submandibular and sublingual salivary duct openings. Palmo-plantar keratoderma, unerupted premolars, congenital absence of lingual frenum, sublingual caruncles, glossy tongue, and pili canaliculi seen in the patient are newly recognized findings of this syndrome. Overlapping findings of RHS ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC), and ankyloblepharon-ectodermal defects-cleft lip and palate syndrome (AEC) are discussed.
