Introduction: The information that details dental changes accompanying presurgical and postsurgical orthodontic treatment during orthognathic surgery treatment is disappointing and results in less than ideal surgical change, but it is largely derived from university clinic samples with patients treated by residents (clinical novices). In this study, we examined similar treatments performed by experienced practitioners and compared them with the novices' results.
Methods: A sample of 72 Class II subjects treated by practitioners with a mean of 26.7 years of experience was selected. Inclusion criteria were consecutively treated surgical-orthodontic patients with mandibular advancement, rigid fixation, and good-quality lateral cephalograms. Pretreatment skeletal and dental variables were compared with those from a sample treated by novices in a previous study. Presurgical and final analyses were performed with analysis of covariance (ANCOVA), with pretreatment values as the covariate. An efficacy analyses for treatment phase and study comparisons was the final component.
Results: The novices treated patients with significantly more severe Class II skeletal problems. For both studies, there were significant positive changes in the position of the mandible. The ANCOVA analysis showed that the experienced practitioners managed the bodily position of the maxillary incisors more effectively. The efficacy analysis showed no statistically significant differences between novices and experienced practitioners. For both novices and experienced practitioners, according to the ANB changes, nonideal incisor decompensation led to less than ideal final mandibular positions.
Conclusions: The dental and skeletal mean changes and efficacy analysis for both novices and experienced practitioners showed that presurgical orthodontic treatment often does not fully decompensate the incisors; this then limits the surgical outcome.

Objectives: The purpose of this study was to propose a new difficulty score for the treatment of multiple gingival recessions (GRs) with Modified Coronally Advanced Tunnel (MCAT), and to test the score's reliability.
Material And Methods: A difficulty score was developed for the assessment and grading of 13 relevant anatomical parameters at baseline. Six experienced dental practitioners evaluated existing GRs in three patients.

Mental health is inherently multidimensional, requiring a holistic approach to intervention that integrates various aspects of an individual's well-being. Spirituality, a vital component of mental health, remains under addressed in Australian mental healthcare. Spiritual care practitioners may play a key role in addressing spiritual needs in mental healthcare; however, their roles and contributions in this context remain unexplored in the extant literature.

The anatomy of the sciatic nerve allows it to be blocked at different levels using various anesthetic approaches. However, for several reasons, performing these approaches may be challenging or disadvantageous in specific categories of patients, particularly in obese patients. The objective of this brief technical report is to describe a new technical approach to sciatic nerve block, designed to simplify the procedure for certain categories of patients and less experienced practitioners.

The increasing popularity of social media and the growth of gourmet food culture have elevated molecular gastronomy as a unique dining experience that enhances consumers' perceptions of value through innovative food presentation and sensory marketing strategies. This study investigates consumer acceptance of molecular gastronomy by utilizing the value-attitude-behavior (VAB) model and the Theory of Planned Behavior (TPB). We examine the interplay between utilitarian and hedonic values, product innovation, and sensory stimulation to understand consumer reactions and attitudes toward molecular gastronomy.
