Major topic: Ectodermal Dyplasia and it’s effects on teeth
Minor topic(s): Treatment options
Main Purpose: To assess the pattern of permanent teeth present in a self selected sample of patients with ectodermal dysplasia(ED) presenting for treatment with dental implants.
Overview of method of research: Panoramic radiographs of 17 female and 35 make patients were examined independently by two investigators to determine the permanent teeth present.
Findings: ED is an inherited disorder in which at least two structures derived from the ectoderm are abnormal. Oral findings of ED can include anodontia, hypodontia, and lack of ridge development. Hypodontia occurs in more than 80% of cases. Studies found that males show more symptoms of missing teeth than females. Physical signs can involve the sweat glands, scalp, hair, nails, skin pigment, and abnormal/underdevelopment of craniofacial structures. The two major types of ED are hypohidrotic, in which sweat glands are absent (most severe, sensitivity to heat, temperature), and hidrotic, in which sweat glands are normal.
The permanent teeth most likely to be present in patients with ED are listed below, starting with the most likely.
1. Maxillary Central Incisor 42%
2. Maxillary 1st molar 41%
3. Mandibular 1st molar 39%
4. Maxillary Canines 22%
5. Mandibular 2nd molars 17%
6. Maxillary 2nd premolars 15%
7. Mandibular premolars 12%
Mandibular anterior teeth were least likely to be present. Considerable research has shown the efficacy of rehabilitating a completely or partially edentulous mandible using implant supported prosthesis. Success rates are in the 90 percentile in adolescents and over 97% in adults(older than 17).
Key points/Summary: Bottom line, if a patient of yours has ED, with hypo/anodontia, implants should be considered as a treatment option. It’s definitive, accepted, proven success and could change a patients quality of life.
Assessment of Article: Money. SO money it doesn’t even know it.
