Background And Aim: Herpes simplex viruses (HSV) are one of the most important groups of human pathogenic viruses. The prominent characteristic of this virus is latency and the ability to reactivate. One of the possible factors for reactivation of this virus is dental procedures. The aim of this study was to evaluate the salivary level of Herpes simplex viruses, before and after periodontal (crown lengthening) surgery and its relation with age and sex.
Materials And Methods: 30 HSV seropositive patients, who needed the crown lengthening surgery and accepted to cooperate in this research, were included as experimental group of this study. Unstimulated Saliva samples of the patients were collected in 1.5 ml micro-tubes, before and 24 h after the surgery, and were analyzed by Premix EX taq probe qpcr, using PCR real-time method.
Results: No significant statistical differences were observed in the salivary level of HSV before and after crown lengthening procedure (p = 0.18). However, the level of HSV in saliva after surgery was significantly higher than its level before surgery in women as compared to men (p = 0.003). The differences in virus level did not have any significant relationship with patients' age (p = 0.9).
Conclusion: It seems that periodontal (crown lengthening) surgery does not affect the level of HSV in saliva yet, but it could be one of the stimulators of increased HSV level after surgery in women as compared to men; but age does not play an important role in changes of level of virus before and after the surgery.

Objectives: To investigate the correlation between gingival thickness (GT) and buccal bone thickness (BBT), as well as the effects of GT, BBT, bone crest level (BC), and tooth position on the buccal gingival margin location of maxillary teeth in the esthetic zone.
Materials And Methods: Periodontally healthy subjects with prior cone beam computed tomography and intraoral scans for dental implant planning were included. The hard and soft tissue measurements were retrospectively analyzed digitally.

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.
