During any dental treatment, various instruments, dental materials, and appliances come in contact with the tissues of the oral cavity. Inappropriate handling of these instruments and materials can cause both hard tissue and soft tissue damage. Periodontal destruction due to iatrogenesis and foreign body impaction is not uncommon. The present case report describes an unusual case of iatrogenic periodontal destruction due to restorative overhang as well as impacted restorative material into the interdental region and its management.

A common problem experienced by adults is the recession of the gingiva resulting in unpleasant appearance of their teeth. There are various techniques to achieve the gingival recession coverage (GRC). But, only few techniques such as connective tissue grafts, coronally advanced flap technique (CAF) have been proved effective in achieving 100% recession coverage. The present study aims at evaluating the efficacy of amnion membrane along with CAF in the management of GRC. Materials and methods: A total number of 10 patients with class I or class II gingival recession were included in the study. The clinical parameters such as Probing depth (PD), clinical attachment level (CAL), thickness of attached gingiva (TAG), width of keratinized gingiva (WKG), height of gingival recession (HGR), percentage of recession coverage (PRC) and recession coverage esthetic score (RCES) were measured at baseline, 3 months and 6 months post-operatively. The patients were treated using amnion membrane in combination with modified coronally advanced flap technique (MCAF). Results: The patients showed statistically significant improvement in all the clinical parameters at the 3 months and 6 months follow-up visit. 97.8% CRC was observed by the end of 6 months. Moreover, the RCES showed remarkable esthetic outcome at the post-operative 6 months visit. Conclusion: Modified coronally advanced flap technique produces excellent clinical outcomes in terms of GRC. The use of amnion membrane aids in faster healing and improves the TAG which is an important aspect for the long term stability of the results obtained.
