Age-dependent root canal instrumentation techniques: a comprehensive narrative review
Solomonov, Michael,Kim, Hyeon-Cheol,Hadad, Avi,Levy, Dan Henry,Itzhak, Joe Ben,Levinson, Oleg,Azizi, Hadas The Korean Academy of Conservative Dentistry 2020 Restorative Dentistry & Endodontics Vol.45 No.1
The aim of this article was to review age-dependent clinical recommendations for appropriate root canal instrumentation techniques. A comprehensive narrative review of canal morphology, the structural characteristics of dentin, and endodontic outcomes at different ages was undertaken instead of a systematic review. An electronic literature search was carried out, including the Medline (Ovid), PubMed, and Web of Science databases. The searches used controlled vocabulary and free-text terms, as follows: 'age-related root canal treatment,' 'age-related instrumentation,' 'age-related chemo-mechanical preparation,' 'age-related endodontic clinical recommendations,' 'root canal instrumentation at different ages,' 'geriatric root canal treatment,' and 'pediatric root canal treatment.' Due to the lack of literature with practical age-based clinical recommendations for an appropriate root canal instrumentation technique, a narrative review was conducted to suggest a clinical algorithm for choosing the most appropriate instrumentation technique during root canal treatment. Based on the evidence found through the narrative review, an age-related clinical algorithm for choosing appropriate instrumentation during root canal treatment was proposed. Age affects the morphology of the root canal system and the structural characteristics of dentin. The clinician's awareness of root canal morphology and dentin characteristics can influence the choice of instruments for root canal treatment.

Effect of Linear Chirp on Strong Field Photodissociation of H_2^+
Vaibhav S. Prabhudesai,Adi Natan,Barry D. Bruner,Yaron Silberberg,Uri Lev,Oded Heber,Daniel Strasser,Dirk Schwalm,Daniel Zajfman,Itzik Ben-Itzhak 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.41
We report the experimental findings of a systematic study of the effect of the linear chirp on strong field photodissociation of H_2^+. For vibrational levels around or above the one photon crossing, the effect manifests in terms of a shift in the kinetic energy release (KER) peaks. The peaks shift up for negative chirp whereas they shift down for positive chirp. The measurements are carried out by varying two of the laser pulse characteristics energy, pulse intensity and linear chirp while keeping the third constant. The shifts in the KER peaks are found to be intensity dependent for a given value of chirp. However, in the last two cases, they are found to be independent of the chirp magnitude. The results are understood on the basis of saturation of photodissociation probabilities for these levels.
