Post-extraction volumetric analysis of alveolar ridge contour using subepithelial connective tissue graft in esthetic zone: a randomized controlled clinical trial.

OBJECTIVES: The aim of this randomized clinical trial was to assess the alveolar ridge contour after soft tissue augmentation using subepithelial connective tissue graft (SCTG) buccal to fresh extraction sockets in patients with thin buccal bone, versus minimally-traumatic extraction followed by spontaneous healing solely. MATERIALS AND METHODS: Forty non-restorable maxillary teeth in the esthetic zone were randomly assigned into two groups: minimally-traumatic extraction with SCTG (test) and minimally-traumatic extraction followed by spontaneous healing (control). The outcomes assessed included linear volumetric change of buccal soft tissue contour, vertical tissue loss, gingival thickness (GT), and interdental papilla (IDP) height after 6 months. RESULTS: The SCTG group showed a significant improvement (P < 0.001) in all outcomes after 6 months. The SCTG group showed a statistically significant (P < 0.001) gain in the buccal soft tissue volumetric change compared to the control group. The SCTG group showed a statistically significant increase in GT (P < 0.001) and IDP height (P < 0.05) after 6 months compared to the control group. CONCLUSIONS: The use of SCTG buccal to extraction sockets in the anterior maxilla might be considered as a predictable approach for preserving the alveolar ridge contour. CLINICAL RELEVANCE: SCTG buccal to extraction sockets might counteract post-extraction hard and soft tissue alterations in the esthetic zone.

Evaluation of needling-induced autoinoculation in the management of genital warts.

BACKGROUND: Genital warts caused by human papillomavirus (HPV) are one of the most common sexually transmitted infections. Long latency, lesions' multiplicity, high recurrence rate, and the tendency to malignant transformation are essential challenges during management. Traditional treatment modalities are known to be lesion-directed while intralesional immunotherapy was introduced to act beyond individual lesions and to confront the previous challenges through injection of known antigens, such as measles, mumps and rubella (MMR) vaccine, to stimulate the immune system against HPV. Needling-induced autoinoculation is also considred as an immunotherapeutic procedure that does not include the injection of antigens. We evaluated the efficacy of needling-induced autoinoculation in the management of genital warts. METHODS: Fifty patients with multiple recurrent (≥4) genital warts were divided into two equal groups. One group was subjected to needling-induced autoinoculation and the other was subjected to intralesional MMR injection every 2 weeks for a maximum of three sessions. Follow-up was done for 8 weeks after the last session. RESULTS: Both needling and MMR showed statistically significant therapeutic outcome. Needling showed significant improvement with regard to the number (P = 0.000) and size (P = 0.003) of lesions. In parallel, MMR showed significant improvement with regard to the number (P = 0.001) and size (P = 0.021) of lesions. There was no statistically significant difference between both treatments outcomes in regard to number (P = 0.860) and size (P = 0.929) of lesions. CONCLUSIONS: Both needling and MMR are effective immunotherapeutic modalities in management of genital warts. Needling-induced autoinoculation, being more safe and inexpensive, may be considered as a competing choice.
