Background: In recent years, a noticeable increase in forensic age estimations of living individuals has been observed. Radiologic assessment of the mineralisation stage of third molars is of particular importance, with regard to the relevant age group. To attain a referral database and regression equations for dental age estimation of unaccompanied minors in an Iranian population was the goal of this study. Moreover, determination was made concerning the probability of an individual being over the age of 18 in case of full third molar(s) development.
Materials And Methods: Using the scoring system of Gleiser and Hunt, modified by Köhler, an investigation of a cross-sectional sample of 1274 orthopantomograms of 885 females and 389 males aged between 15 and 22 years was carried out. Using kappa statistics, intra-observer reliability was tested. With Spearman correlation coefficient, correlation between the scores of all four wisdom teeth, was evaluated. We also carried out the Wilcoxon signed-rank test on asymmetry and calculated the regression formulae.
Results: A strong intra-observer agreement was displayed by the kappa value. No significant difference (p-value for upper and lower jaws were 0.07 and 0.59, respectively) was discovered by Wilcoxon signed-rank test for left and right asymmetry. The developmental stage of upper right and upper left third molars yielded the greatest correlation coefficient. The probability of an individual being over the age of 18 is 95.6% for males and 100.0% for females in case four fully developed third molars are present. Taking into consideration gender, location and number of wisdom teeth, regression formulae were arrived at.
Conclusion: Use of population-specific standards is recommended as a means of improving the accuracy of forensic age estimates based on third molars mineralisation. To obtain more exact regression formulae, wider age range studies are recommended.

The major components of tea leaves and their infusions were analyzed for various types of green tea available in Japan in 2022. Almost all the green teas used were from the first crop, known for their high amino acid content. The amino acids theanine and arginine in green tea have been shown to reduce stress.

Importance: Rhesus alloimmunization refers to the sensitization of an Rh D-negative mother after exposure to D-positive fetal red blood cells, which can lead to significant fetal and neonatal morbidity and mortality.
Objective: The aim of this study was to review and compare the most recently published international guidelines on the prevention of maternal alloimmunization.
Evidence Acquisition: A comparative review of guidelines from the American College of Obstetricians and Gynecologists, the British Committee for Standards in Hematology, the International Federation of Gynecology and Obstetrics, the Royal Australian and New Zealand College of Obstetricians and Gynecologists, and the Society of Obstetricians and Gynecologists of Canada regarding the prevention of maternal Rh D alloimmunization was conducted.

Objectives: To externally validate a clinical prediction model for surgical site infection (SSI) after lower third molar (L3M) surgery and evaluate its clinical usefulness.
Methods: We conducted a retrospective cohort study of patients who underwent L3M surgery at Hokkaido University Hospital. The study was designed to evaluate the historical and methodological transportability.

Aim: This study aims to evaluate the impact of platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) on pain, swelling, trismus, soft tissue healing and bone regeneration following mandibular third molar extraction.
Material And Methods: A systematic review was conducted from a period of January 2014 to June 2024 using PRISMA guidelines. The search strategy included databases such as Scopus, PubMed, Google Scholar, and Cochrane Central Register of Controlled Trials, using key terms related to "PRF", "PRP", oral surgery, and third molars.

Background: It has been outlined that LTM (Lower third molar) extracted from patients in which grinding, cleaning, sterilization & demineralization prove to be highly effective as graft material for filling the alveolar socket of the very same patient. These investigations aim to assess the efficiency of ADDM (Autogenous Demineralized Dentin Matrix) graft in third molar extraction sockets.
Purpose: To check the effectiveness of ADDM as graft material in extraction socket by evaluating pain, swelling, trismus, PD (Probing Depth) and bone density.
