Digital prediction of smile line transition by using 2D photowrapping.

Dental practitioners often rehabilitate patients with excessive gingival display during the broad wide smile. The transition line is defined as the lip line, which depicts transition between the prosthesis and adjacent soft tissue. Correctly predicting and managing this transition line is especially important, as it determines esthetics when the patient smiles widely.

Effect of the Time Interval of Functional Loading on the Periapical Healing of Endodontically Treated Mandibular Molar Teeth with Pulp Necrosis and Asymptomatic Apical Periodontitis: A Split-mouth Randomized Clinical Study.

Introduction: This prospective study evaluated the effect of immediate functional loading (IFL) of a full-coverage prosthesis on the clinical and radiographic outcome of nonsurgical endodontic therapy (NSET) performed on mandibular molar teeth with pulp necrosis and asymptomatic apical periodontitis.

Methods: In 20 subjects, standardized 2-visit NSET was performed in bilateral mandibular first molar teeth (split-mouth model) with a diagnosis of pulp necrosis and asymptomatic apical periodontitis exhibiting a radiographic periapical index (PAI) score ≥3. In each subject, the nonvital bilateral mandibular first molar teeth were randomized to 1 of 2 groups: the IFL group or the functional loading after a time interval of 6 months group.

Psychosocial factors among patients undergoing orbital exenteration.

Clinical Relevance: Patients undergoing exenteration have significant anxiety and depression, and lower quality of life that worsens after surgery. Therefore, counselling by an eye health-care provider along with the team of psychologist and psychiatrist could be provided pre-operatively to assess baseline psychosocial status and be continued post-operatively to look for any deterioration.

Background: Orbital exenteration comes with psychological trauma of disfigurement of face.

Soil degradation kinetics of oxybenzone (Benzophenone-3) and toxicopathological assessment in the earthworm, Eisenia fetida.

A preponderance of recent evidence indicates that oxybenzone and other personal-care product chemicals threaten the biota inhabiting various ecological niches. What is understudied is the ecotoxicological impact of oxybenzone, a UV filter in sunscreens and anti-aging products, to terrestrial/soil organisms that are keystone species in these habitats. In the present study, acute exposure (14-day) to oxybenzone resulted in earthworm mortality (LC of 364 mg/kg) and growth rate inhibition.

Vertical Bone Implant Contact Around Anterior Immediate Implants and Their Stability After Using Either Alloplast or L-PRF or Both in Peri-Implant Gap: A Prospective Randomized Trial.

Purpose: Various graft materials have been studied for filling peri-implant gap (PIG), but there was no similar randomized clinical trial to evaluate the effect of Platelet-rich fibrin or alloplast or their combination on vertical bone implant contact (BIC) around immediate implants and their stability over a period of 1 year.

Methods: Immediate implants were placed in maxillary anterior region of 30 subjects ( = 10). Either alloplast (group I) or L-PRF (group II) or both (group III) were used to fill the PIG following randomization chart.

A study on bisphenol S induced nephrotoxicity and assessment of altered downstream kidney metabolites using gas chromatography-mass spectrometry based metabolomics.

The global use of bisphenol S (BPS) has now been significantly increased for commensurate utilization as a substitute for BPA for its regulatory concerns. Though, previous reports indicated that BPS been also appeared as a toxic congener comparable to BPA. In the present study, we determined nephrotoxicity condition induced due to BPS exposure.

Metabolomic perturbation precedes glycolytic dysfunction and procreates hyperglycemia in a rat model due to bisphenol S exposure.

Previous studies highlighted bisphenol S (BPS), an industrial chemical responsible for harmful effects comparable to its congener substance bisphenol A (BPA). Accounted for various adversities to biological functions, it could alter the expression of endogenous metabolites in many metabolic processes. The study was aimed to investigate the altered metabolites in hyperglycemic condition triggered by sub-chronic exposure of BPS in serum and urine samples of Wistar rats.
