Biting and chewing by horses on crossties can result in injury to the handler and damage to equipment. Operant-conditioning techniques have been used to train horses and could be used to reduce or eliminate undesirable biting and chewing. Presently, a differential-reinforcement-of-other-behavior (DRO) schedule, in the context of a reversal design, was effective in reducing biting and chewing in two horses. In DRO schedules, a reinforcer is delivered contingent on the absence of a target behavior for a specified interval. Positive-reinforcement procedures offer an alternative to aversive-control techniques typically used in equine training and may provide for better equine welfare and horse-human interaction.

Objectives: This study aims to detect early class I, II, and III malocclusions through the muscle strength of the lips, tongue, masseter, and temporalis.
Materials And Methods: The study subjects were 30 pediatric patients with predetermined criteria. The subjects were divided into class I, II, and III malocclusions where each classification of malocclusion amounted to 10 people.

The anatomy of molar teeth is important both functionally for chewing food and in evolutionary studies as a well-preserved species marker in the fossil record. Molar teeth begin to develop their characteristic biting-surface shape of cusps (peaks) and sulci (valleys) at the bell stage, when corresponding folds in the dental epithelium become apparent. Theories about the developmental mechanisms of cusp and sulcus morphogenesis have hitherto largely focused on the non-proliferating nature of the secondary enamel knots (EKs) at the cusp tips.

Aim: This study aimed to determine the relationship between malocclusion and deleterious oral habits in the Vietnamese children aged 8-12 years.
Materials And Methods: A cross-sectional descriptive analysis was undertaken on a total of 434 children (8-12 years old, 208 males and 226 females), separated into five age groups: 8 years old (16.8%), 9 years old (18.

Objectives: To evaluate the changes in nutritional status, chewing ability and oral health-related quality of life in edentulous individuals who have initially been rehabilitated with immediate complete dentures (CD) which are then transformed to implant-supported overdentures (IOD) after a period of osseointegration.
Background: Compared to those with conventional dentures, individuals with IODs exhibit improved patient-reported outcomes, chewing capacity and biting force. While prior research highlights differences in nutritional markers between these groups, there is limited investigation into intra-individual changes in nutritional status, chewing ability and oral health-related quality of life during the transition from CDs to IODs.

Teeth malocclusion refers to the misalignment of teeth and improper occlusion of the upper and lower jaws when the mouth is closed, which can lead to both aesthetic and functional issues such as difficulties with chewing, biting, and speech. These challenges may further contribute to broader health concerns. One of the major contributing factors to malocclusion in children is the presence of certain oral habits.
