Medicinal plants are an important source of bioactive compounds and have been used to isolate various bioactive compounds having industrial applications. The demand for plants derived bioactive molecules is increasing gradually. However, the extensive use of these plants to extract bioactive molecules has threatened many plant species.

- The study aimed to evaluate the oral health and hygiene of 300 children aged 2-16 years with congenital heart disease (CHD).
- Results indicated a poor oral health status, with 56.7% of participants experiencing dental caries and a notable prevalence of dental anomalies, including enamel opacities in 8% of cases.
- The findings suggested that older children had worse oral health metrics, with higher scores for caries and dental indices among those with cyanotic CHD compared to those with acyanotic CHD.
Purpose: The purpose of the study was to evaluate by a 3-dimensional finite element analysis the load transmission to periimplant bone by a framework supported by 6 implants placed in an edentulous mandible and to compare the stress distribution for varying cantilever lengths.
Methodology: A computerized model of the anterior segment of a mandible with a 6-implant-supported bridge was created in software. The length of the cantilever segment was considered as 10, 15, and 20 mm.
Purpose: This study evaluated the microbial colonization of dental implants in healthy patients before placing the implants and during the various stages of implant treatment.
Materials And Methods: Saliva (in completely edentulous patients) and gingival crevicular fluid samples (in partially edentulous patients) were collected from patients and analyzed to estimate the growth of microorganisms after culture. Samples were collected during 10 phases of implant placement and prosthesis insertion.
Background: The success of dental implants depends on the manner in which stresses are transferred to the surrounding bone. An important consideration is to design an implant with a geometry that will minimize the peak bone stresses caused by standard loading. The aim of this study was to assess the influence of implant thread geometry on biomechanical load transfer and to compare the difference between two different thread designs.

- This meta-analysis compares conventional implant designs to "platform-switched" implants, focusing on their impact on crestal bone loss.
- A thorough literature review analyzed various studies, finding that platform-switched implants led to significantly less marginal bone loss than platform-matched implants.
- The study concludes that platform switching may help maintain bone and tissue levels around implants, but more long-term studies are needed to fully understand its effectiveness and optimal design.
Statement Of Problem: Although criteria for assessing bone quality have been reported, an overall score that correlates bone quality with the primary stability and secondary stability of implants is not yet available.
Purpose: The purpose of this article was to propose a scoring index that will establish a correlation among the bone density values from computed tomography, maximum insertion torque values, and resonance frequency analysis in different phases of implant treatment.
Material And Methods: In this study, 60 implant sites were evaluated to assess bone density (Hounsfield units), insertion torque values (Ncm), and primary stability and secondary stability (implant stability quotient values obtained by using resonance frequency analysis).
