Does LeFort I Surgery Have Any Influence on External Root Resorption?

Objective: The aim of our study was to evaluate root resorption on maxillary teeth neighboring osteotomy sites in response to segmental LeFort I osteotomy over time.

Methods: Eighteen subjects, aged 18 to 65 years with pre-surgery (T0), post-surgery (T1), and long-term follow-up (T2) CBCT records were included. Sixteen control subjects, aged 17.

The impact of extracts on biofilm formation.

Background/objectives: plants have a wide range of anti-inflammatory and antimicrobial activities. This study aims to assess the antibacterial effect of water, methanol, and ethanol extracts of against biofilms.

Methods: Three extracts of were prepared using water, methanol, and ethanol.

Hairy Cell Leukemia and Its Mimics: A Case-Based Exploration of Diagnostic Complexity.

Hairy cell leukemia (HCL) is a rare but well-characterized B-cell malignancy with distinct immunophenotypic and genetic features. Advances in molecular diagnostics, particularly the identification of the BRAF V600E mutation, have significantly enhanced diagnostic precision and informed targeted treatment strategies. However, the HCL variant and other HCL-like syndromes continue to present substantial diagnostic challenges due to their absence of BRAF mutations, atypical immunophenotypic profiles, and divergent clinical courses.

Effect of damage or contamination to the tips of 200 light-curing units.

Objective: The light-curing unit (LCU) has become a vital piece of dental equipment that must be correctly maintained. This study investigated the impact of contamination and physical damage to the light tip on the power and radiant emittance values from old and new LCUs.

Materials And Methods: Two investigators assessed 200 LCUs in dental clinics.

Maxillary Incisor Fragment Reattachment Protocols: Influence on Tooth Fracture Resistance and Strength of Bonding to Orthodontic Brackets.

: Trauma to maxillary incisors is frequent, and requires timely, conservative management for optimal prognosis. This in vitro study evaluated the fracture resistance (FR) and orthodontic bracket bond strength (BS) of incisors following incisal fragment reattachment using various restorative techniques. : Two independent tests-FR testing (Newtons) and BS testing (megapascals)-were conducted.
