Gummy smile has been a prevalent esthetic disorder commonly affecting younger individuals due to various causes such as skeletal, dento-alveolar, or soft-tissue origin. It can be due to jaw deformities, altered passive eruption, or tooth malpositioning. Usually, the corrective measures incorporate orthognathic surgery and orthodontic treatment. Orthognathic surgery results in significant morbidity and hospitalization. Lip repositioning can be employed as an alternative cosmetic treatment modality for the correction of an excessive gingival display with minimal risk or side effects. Although there are many articles existing in the literature on this topic, a series of three cases is unique in demonstrating the esthetic smile enhancement in an orthodontic patient and also a combination of lip–repositioning technique and laser-assisted crown lengthening in vertical maxillary excess cases. This case series also showed the predictability of lip-repositioning technique with a follow-up of 2 years.

Generalized aggressive periodontitis (GAP) is a debilitating form of the disease and it results in deteriorating effects on the esthetic and functional aspects of the oral cavity. This case report describes the comprehensive rehabilitation of GAP patient using dental implants. The treatment planning involved thorough scaling and root planning (SRP) with oral hygiene instructions. The patient was motivated to adhere to a strict oral hygiene regimen following which periodontal flap surgery employing guided tissue regeneration and bone grafts was performed. Bacterial culture for anaerobic microorganisms was done using a gas pack pre- and postperiodontal treatment to confirm the effectiveness of the periodontal treatment regimen and also to proceed with dental implant placement. The rigorous maintenance program ensured the stability of the periodontium following which immediate placement of dental implants in the maxillary and mandibular anterior region was done. The fixed metal-ceramic prosthesis was fabricated in a step-by-step process and the patient was recalled on a periodic basis over a 3-year follow-up duration. This case is a testimonial to the postperiodontal treatment long-term stability with excellent patient cooperation and strict maintenance protocol.

Our studyshowed that the prevalence of EBV1 was higher in chronic and aggressive periodontitis subjects compared to controls and the prevalence of CMV was higher in aggressive periodontitis patients. The virus positive sites showed higher pocket depth compared to virus negative sites.
