Objective: To observe replacement of missing teeth with artificial teeth in subjects with and with out cardiac diseases and find its possible association with coronary heart diseases (CHD).
Methodology: Consecutive patients aged 20 and above with coronary heart disease and accompanied healthy subjects with tooth loss were examined for oral prosthesis after having a verbal consent, over a one month period in a cross-sectional study at Punjab Institute of Cardiology, Lahore. Chi-square and T- test were applied to analyze variables in subjects with and without coronary heart disease.
Results: Among 1694 subjects found with tooth loss, 1473 (86.95) subjects had no oral prosthesis; 817 (87.37%) were among the 935 cardiac patients and 656 (86.42%) among 759 healthy subjects. Oral prosthesis was found in 86 (8.05%) males and 32 (5.11%) females with coronary heart diseases. Of the healthy population, 46 (4.30%) males and 57 (9.10%) females had oral prosthesis. Statistical association for prosthesis was insignificant among cardiac patients and healthy subjects.
Conclusion: No association of uncompensated tooth loss with cardiac diseases was observed in this study. Although a large majority of cardiac patients and healthy subjects were observed with uncompensated tooth loss which was statistically insignificant.

Objective: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes of adhesion according to the FDI criteria. The primary outcome was the retention loss of the restorations, while the secondary outcomes included marginal staining, marginal adaptation, post-operative sensitivity and tooth vitality, recurrence of caries erosion and abfraction, and tooth integrity, all evaluated according to the FDI criteria.
Materials And Methods: In this study, the SBU Adhesive was applied to 246 NCCLs of 25 patients using different modes of adhesion: Self-etch (SE), selective-enamel-etching (SLE), and etch-and-rinse (ER).

Unlabelled: Peri-implantitis (PI) is an inflammatory disease that affects supportive tissues around dental implants, and its progression eventually leads to bone loss and implant failure. However, PI effects may be different based on the presence or absence of adjacent teeth.
Objective: To investigate the differences in bone loss and inflammation between implants placed adjacent to a tooth or edentulous area in a ligature-induced PI model.

Background: The pre-extraction overbuilding procedure was designed aiming to mitigate buccal bone resorption following tooth extraction. The objective of this study was to compare the efficacy of pre-extraction and juxta-extraction buccal overbuilding treatments in preserving buccal bone volume following tooth extraction.
Material And Methods: At the test sites (pre-extraction sites), an alveolar crest overbuilding was performed on the buccal aspect of the distal root of the fourth premolar using a xenograft covered with a collagen membrane.

Statement Of Problem: Endodontically treated teeth often require post-and-core restorations for structural support because of extensive hard tissue loss. Assessment of the effect of the residual dentin thickness on the biomechanical performance of these restorations is lacking.
Purpose: The purpose of this study was to evaluate the residual dentin thickness in mandibular premolars after post-and-core restorations using cone beam computed tomography (CBCT) and to analyze the stress distribution with finite element analysis (FEA).

Electronic address:
Metabolic pathways exhibit fluctuating activities during bone and dental loss and defects, suggesting a regulated metabolic plasticity. Skeletal remodeling is an energy-demanding process related to altered metabolic activities. These metabolic changes are frequently associated with epigenetic modifications, including variations in the expression or activity of enzymes modified through epigenetic mechanisms, which directly or indirectly impact cellular metabolism.
