Pain and discomfort during orthodontic treatment: causative factors and effects on compliance.

1998

Orthodontic patients experience pain and discomfort to a varying degree during the course of treatment. The aims of the present investigation were to follow the progress of adaptation after insertion of new appliances and to study the relationships between the type of appliance worn and pain or discomfort experienced, between pain sensations and attitude toward the treatment and their effects on patients' compliance. Pain and discomfort experienced by 84 patients undergoing orthodontic treatment, their attitude toward the treatment, and compliance were assessed 7 days, 14 days, 6 weeks, 3 months, and 6 months after appliance insertion, using specially designed protocols, questionnaires, and…

Effects of maxillary protraction determined by laser metrology

1990

In this work we studied some of the main effects of the maxillary protraction orthopedic device. The initial dento-craniofacial reactions induced by maxillary protraction similar to that commonly employed in clinical practice are reported. The fringe counting holographic interferometry technique is used to measure displacements. The experiments were performed on a dried human skull; traction application points were situated over the permanent lateral incisors or over the first permanent molars. The results fundamentally reveal an anterior rotation of the dentomaxillary complex, more intense when traction is applied to the lateral incisors, as shown by a more marked extrusion of the molars i…

Human dental pulp cell apoptosis: immunohistochemical study after applying orthodontic traction.

2012

The aim of this study was to compare human dental pulp stress and programmed cell death after 3 and 6 months of orthodontic treatments by assessing the degree of apoptosis and related proteins. Human dental pulps were collected from twenty young patients orthodontically treated by Straight Wire technique. Samples were fixed, paraffin-embedded and processed for histology and immunohistochemistry using anti-heat shock protein 60 kDa (Hsp60), -caspase 3, -caspase 9, and -PCNA antibodies, as well as TUNEL reactions. Moreover, we performed immunoprecipitation for Hsp60 and caspase 3, and for Hsp60 and caspase 9, from paraffin extracted tissues. Increased levels of both caspases and Hsp60 occurre…

Prosperare al di là del merito: il senso della nemesis in Aristotele tra giustizia distributiva e giustizia correttiva

2017

L’articolo prende in esame quella particolare forma di indignazione che Aristotele indica, nel secondo libro della Retorica, con l’infinito sostantivato to nemesan, derivato dal termine nemesis. Si tratta della reazione che si genera in un animo nobile contro chi prospera al di là del merito. Il sostantivo e i suoi derivati risultano poco usati in età classica e ricorre più frequentemente nell’epica omerica e in Esiodo. Aristotele sembra recuperarlo proprio dalla tradizione poetica arcaica, assegnandogli un ruolo nella sua riflessione sulla giustizia e in particolare nella differenza tra la forma distributiva e quella correttiva. Egli individua così in questa forma di indignazione, un’emozi…

[tyʁlyty’ty/ləʃapopwɛ̃’ty] (Turlututu, le chapeau pointu) ou de la perception à la production de la voyelle /y/ par des apprenants polonophones

2019

Our basic assumption is that all voices are born from listening. We will focus on the pronouncing difficulties of the vowel /y/ by Polish learners of level A1/A2: a preliminary descriptive and comparative study, corroborated by an acoustic study, determined that the phoneme /y/ is often pronounced: 1) too posterior and/or too loose (thus tending towards the /u/); 2) too anterior (tending towards the /i/). However, the vowels /i/ and /u/ exist in Polish and are the closest corresponding sounds to the vowel /y/, absent in the Polish vocal system. This acoustic study is based on three phases of data recording/analysis: I) diagnostic phase—to detect the tendency of each speaker on the axis of a…

Dynamic Potential of Feedback in Self-Regulated Learning and Motivation of Children with Mathematical Learning Difficulties

2017

The present study was designed to examine the effects of feedback conditions on learning and motivation of children identified with mathematical learning difficulties (MLDs). The performance of 76 fifth grade children on computational math skills and related task motivation was assessed. The groups of children were randomly assigned to one of two treatment conditions: immediate corrective feedback or delayed conventional feedback on two occasions. Results showed that children performed significantly better when they were provided with the immediate corrective feedback than when they were provided with the delayed conventional feedback. The findings suggest that provision of the immediate co…

Developing Peer Corrective Skills in Business Letter Writing in English as a Foreign Language

2019

Peer corrective feedback (PCF) implementation is a topical issue in writing skills development at tertiary level. Those researchers who explore the application of PCF in higher education (e.g. Liu and Sadler, 2003; Hyland, K. and Hyland, F., 2006) admit that students face difficulties in providing quali­ta­tive feedback that determines the effectiveness of this teaching tool. Therefore, the goal of this paper was to investigate what actions could be taken in order to develop students’ PCF skills and, consequently, foster the quality of PCF. The primary research method was a case study in which the participants were 24 second-year undergraduates majoring in English as a Foreign Language (EFL…

Orthopedic-orthodontic treatment of the patient with Turner's syndrome: Review of the literature and case report.

2018

Aims Turner syndrome (TS) patients have phenotypical variable presentations and they are more susceptible to endocrine, auto-immune, and structural anomalies. Typical clinical characteristics are short stature and premature ovarian insufficiency. Patients with TS show a typical cranial-facial morphology with bi-maxillary bi-retrusion, high-arched palate, micrognathia, and class II malocclusion. Aim of our study is to present the orthopedic-orthodontic treatment approach of a young TS patient and data of stability after 7 years. Methods and results A careful analysis of anamnestic data was performed. After extraoral and intraoral examination, cephalometric measurements and examination of mod…
