The presence of subgingival pathology, such as a deep secondary caries lesion, a fracture, an already existing restoration that needs to be replaced or the presence of a resorption defect, can constitute a difficult starting situation for the preservation of a tooth. How to deal with such a situation has been a topic of discussion for years. Surgical crown lengthening is one of the first and classic treatment options that is often chosen in such cases. Crown lengthening is a periodontal surgical technique to obtain extra supra crestal clinical crown length. The question is, what is the long-term prognosis of teeth after surgical crown lengthening. To answer this question, a review of the literature was carried out looking for clinical studies examining survival. Four studies with a follow-up of at least 5 years were included. The factors that adversely affect survival of the tooth after the crown lengthening are an unfavourable crown-root ratio, insufficient plaque control and moderate ability to keep the restoration clean.

Excessive gingival display (EGD), commonly known as a gummy smile (GS), is a cosmetic concern that involves exposing a significant area of gum tissue during a smile, rendering it unaesthetic. Gingival exposure greater than 3 mm is deemed aesthetically displeasing and often necessitates treatment to mask the gummy smile. The causes of EGD are multifactorial, including altered passive eruption (APE), hypermobile upper lip (HUL), short lip length, increased vertical maxillary component, gingival hyperplasia, dentoalveolar extrusion, and more.

Objectives: This report illustrates the digital interdisciplinary management of a case presenting with diastemata, a retained primary tooth, microdontia, and hypodontia. Esthetic crown lengthening and ultrathin veneers optimized the natural dentition and achieved a stable, minimally-invasive, and esthetically-pleasing outcome.
Clinical Considerations: Reduction guides were digitally-designed and 3D-printed for guided crown lengthening and dental veneer preparation.

Introduction: In recent years, erbium-doped yttrium aluminum garnet (Er:YAG) and erbium, chromium/yttrium-scandium-gallium-garnet (Er,Cr:YSGG) lasers have been introduced as another possibility to perform less-invasive flapless (FL) crown-lengthening (CL) procedures.
Objectives: The aim of this review is to describe the outcomes and complications of this approach.
Materials And Methods: A literature review was conducted to retrieve clinical studies and case reports that analyze different variables related to laser-assisted flapless crown lengthening and report their outcomes in terms of gingival margin level stability (GMLS), and postoperative complications.

The main principles of management of children with root fractures of permanent teeth in the coronal third are presented using two clinical cases as an example. In the treatment of root fractures in the coronal third, an important condition for success is timely flexible or semi-flexible splinting of the tooth for a sufficiently long period (up to 4 months). In the absence of splinting or significant mobility of the coronal fragment after removal of the splint the probability of pulp necrosis is very high, and the method of choice is treatment with calcium silicate cements with their introduction by orthograde or surgical access.

Background: Preservation of a healthy periodontium is critical for the long-term success of restored teeth. In cases of extensive caries, tooth fracture, inadequate crown length, and increased esthetic demands, the restorative margins need to be placed apical to the gingival margin. Violation of the biological width due to dental trauma frequently appears in clinical practice.
