Ectodermal dysplasia (ED) is a inherited genetic disorder with manifestations of abnormalities in more than one ectodermal derivatives like skin, hair, nails, exocrine glands and teeth. There are more than 150 different variants of ED described in literature. The condition is thought to occur in approximately 1 in every 100,000 live births. It mainly manifests in two types i.e. Hypohidrotic (Anhidrotic) type and Hydrotic type depending on degree of sweat gland function. This report presents two cases within a family, a 4 year old boy and a 6 year old girl with typical features of Hypohidrotic Hereditary ED i.e, hypodontia, hypohidrosis and hypotrichosis.

Bony defects caused by periodontitis are often treated by regenerative therapy using autografts and/or allografts. Alloplasts such as hydroxyapatite or ceramics and bioactive glasses are used as osteoconductive materials that serve as scaffold for new bony ingrowth. The purpose of this study was to ascertain the possible regenerative capability of glass reinforced hydroxyapatite (Bonelike¬)¬¬¬ an osteoconductive synthetic graft in the treatment of human periodontal intrabony angular defects. The material was placed in 2 defects in 2 individual patients and clinical parameters such as probing depth (PD) and clinical attachment level (CAL) have been included. Bone fill was determined using an intra oral periapical radiograph (IOPA) and Autocad Software. After 3 months implantation period, there was an improvement in CAL and reduction in PD along with bone fill was observed.
