AbstractA method is described for using vinyl polysiloxane dental impression material to make high definition casts from ceramic objects that bear negative imprints of textiles. Casts made from impressions found on prehistoric ceramic figurines from Ecuador were examined under magnification and features of the yarns and weaves were described. The data are used to reconstruct prehistoric spinning and weaving technology. The use of cloth in figurine manufacture and the reconstructed textile technology are interpreted in spatial, temporal and cultural perspectives.

Quick setting dental impression materials are nothing new in the paleontology laboratory. In a paleontological note published in the Journal of Paleontology on “The Use of Dental Impression Material For Molding Macrofossils” (Quilty & Williams, 1975), the products Xantopren and Optosil were introduced as a simple and fast method of obtaining precision molds in 1-3 minutes. Since the mid-1970's these products have been replaced by vinyl polysiloxanes.

Oral mucocele is a benign cystic exophytic lesion affecting the minor salivary gland and is especially present in pediatric patients (3% under 14 years). It is characterized by an extravasation or retention of fluid or mucus in the submucosal tissue of the minor salivary glands. Several surgical techniques have been proposed over the years, including the excision of the mucocele by using the injection of a hydrocolloid impression material in the light of the cyst to prevent the collapse of the cystic wall and solidify the lesion, resulting in a better cleavage plan. The combined clinical approach between the combination of Shira’s technique and the surgical excision of the cystic lesion results in a conservative surgical removal of the lesion. Here, we reported the removal of a labial mucocele in a 14-year-old male patient, using the injection of a hydrocolloid impression material. At a 12 months follow up, the patient showed complete healing of the surgical site, showing a pinkish lip lining mucosa without scarring or recurrence of the primary lesion. The combined therapeutic approach between Shira’s technique and surgical excision allows a safe and predictable excision of the labial mucocele, minimizing the risk of recurrence.
