Artificial light at night disrupts male dominance relationships and reproductive success in a model fish species.

Environmental light is perceived and anticipated by organisms to synchronize their biological cycles. Therefore, artificial light at night (ALAN) disrupts both diurnal and seasonal biological rhythms. Reproduction is a complex physiological process involving integration of environmental signals by the brain, and release of endocrine signals by the pituitary that regulate gametogenesis and spawning.

Sperm Collection and Computer-Assisted Sperm Analysis in the Teleost Model Japanese Medaka (Oryzias latipes).

Japanese medaka (Oryzias latipes) is a teleost fish and an emerging vertebrate model for ecotoxicology, developmental, genetics, and physiology research. Medaka is also used extensively to investigate vertebrate reproduction, which is an essential biological function as it allows a species to perpetuate. Sperm quality is an important indicator of male fertility and, thus, reproduction success.

Learning environments' influence on students' learning experience in an Australian Faculty of Business and Economics.

We investigated how learning environments-involving their physical, pedagogical, and psychosocial dimensions-influence students learning experiences in an Australian Faculty of Business and Economics. Qualitative data collection involved observations of eight classrooms over a semester, four focus groups with 21 students and interviews with six educators. The study provided deeper understanding of the dynamic and complex intrinsic interrelations of learning environment dimensions over time, addressing previous gaps in research.

Fifteen-year Clinical Follow-up of Restoration of Extensive Cervical Resorption in a Maxillary Central Incisor.

Internal bleaching in endodontically treated teeth requires care and protection to prevent harm to the periodontal ligament due to peroxide and may result in external root resorption. There is a myriad of treatment options when this occurs, such as monitoring, extraction, and subsequent rehabilitation with implants or fixed prosthodontics. In some cases, such as the one described here, a conservative attempt to maintain the tooth as a single structure can be made by sealing the resorptive defect.

Root Resorption a 6-Year Follow-up Case Report.

This paper describes the clinical course of a pediatric patient developing cervical external root resorption (CERR). An 11-year old male patient had sustained dental trauma and was diagnosed with crown fracture affecting the incisal and middle thirds of the maxillary right permanent central incisor and the maxillary right permanent lateral incisor with pulp exposure and CERR after 24 months. Diagnosis and treatment of CERR are a challenge for dental practitioners.

Association between post-orthodontic treatment gingival margin alterations and symphysis dimensions.

Orthodontic therapy is known to be associated with the development of gingival recession. Several factors may be involved in the causal chain of this outcome, including anatomical and behavioral aspects. Among the anatomical aspects, the dimensions of the mandibular symphysis could play a predisposing role.

Materials And Methods: A cross-sectional study was carried out with 704 adolescents aged 12 and 13 years at municipal public schools in the city of Balneário Camboriú (southern Brazil). The adolescents answered a previously tested questionnaire addressing satisfaction with their dental appearance, speech function, chewing function, and the desire for orthodontic treatment.

Esthetic rehabilitation of a patient with severe oligodontia.

Oligodontia, or the congenital absence of teeth, can occur in isolation or as part of a syndrome. This study describes a case of isolated oligodontia associated with conical teeth and large diastemas in the anterior region. The patient was treated using direct composite resin restorations.

Esthetic and functional rehabilitation for oligodontia in the mixed dentition: case report.

Tooth agenesis can be considered the most common anomaly of craniofacial development in humans, with an estimated prevalence reaching up to 20% worldwide. Treatments for tooth agenesis include orthodontic space closure, use of fixed or removable dentures, and placement of dental implants. Some of these options may not be applicable to children in mixed dentition because they can prevent the normal development of facial bones.

Dentofacial deformities are associated with lower degrees of self-esteem and higher impact on oral health-related quality of life: results from an observational study involving adults.

Purpose: Patients with dentofacial deformities tend to show poorer oral health-related quality of life, but few studies thus far have focused on this topic. Therefore, the objectives of this study were to evaluate oral health-related quality of life, self-esteem, and depression in patients with Class II and Class III dentofacial deformities before orthodontic treatment and to compare these patients with controls with harmonic faces.

Materials And Methods: This observational, cross-sectional study compared 2 groups (experimental vs control) of patients recruited at an outpatient orthodontic clinic.

Aarskog-scott syndrome: a review and case report.

This paper reports the treatment and 12-year follow-up of a patient 7 years old who had been diagnosed with Aarskog-Scott syndrome. The patient had a history of premature multiple tooth loss, vertical dimension loss and severe dentoalveolar discrepancy. Orthopedic and orthodontic rehabilitation treatments were performed to improve the patient's esthetic, functional and psychological condition.

Orthodontic-restorative treatment as an option for biologic replacement of a maxillary central incisor: 5-year follow-up.

The maxillary central incisor is the tooth most often affected by trauma, especially in the age range of 7 to 10 years, when high-impact sports are prevalent. The options for conservative treatment should be prioritized in these patients, aiming to achieve a biologic response that might provide continuity of growth of the alveolus, to provide functional and esthetic development of the affected region. This case report describes a patient with a history of trauma during the deciduous dentition with consequent intrusion, root dilaceration, and retention of the maxillary left central incisor.

Multidisciplinary approach in the rehabilitation of missing lateral incisors: a new trend in daily practice.

This article reports the case of a patient with bilateral hypodontia of the maxillary lateral incisors who was dissatisfied with the outcome of initial orthodontic treatment, highlighting the importance of a multidisciplinary interaction among Restorative Dentistry, Orthodontics, and Implantology to achieve satisfactory esthetics and functional results.
