What is the principal factor involved in oral para-function?

The principal factor involved in oral para-function is primarily linked to periods of stress. Stress can lead individuals to engage in habits like teeth grinding (bruxism), clenching, or other forms of oral activities that occur outside of normal chewing or speaking. These para-functional behaviors often arise as coping mechanisms during times of emotional or psychological distress, thereby contributing significantly to various dental issues such as tooth wear, jaw pain, and even temporomandibular joint disorders.

While other factors, such as occlusal pre-maturities, improper dental restoration, and jaw alignment issues, can indeed contribute to or exacerbate para-functional habits, they are often secondary to the overarching influence of stress. Stress creates the conditions that may prompt the individual to engage in para-functional activities rather than being the primary cause of the activities themselves. Understanding this relationship helps in developing preventative strategies and treatments that address the underlying stress rather than just the symptoms manifested in oral health.
