DM,

2. Neurological disorders and affections of the orodental tissues
Antiepileptic drugs
Epilepsy - a chronic disorder with unpredictably recurring seizure
Epil.seizure - risk of oro-facial trauma
Antiepileptic drugs (AED) - side effects in the oral cavity (Valproate acid) - Gingival over growth

3. Neurological disorders and affections of the orodental tissues
Head injuries: oro-facial injuries
lip and cheek biting- most common soft tissue injury
tooth fracture - most common hard tissue dental injury

4. Neurological disorders and affections of the orodental tissues
Neurocutaneous (phakomatosis) diseases:  Sturge- Weber syndrome, tuberous sclerosis, neurofibromatosis of von Recklinghausen and incontinentia pigmenti.
Tumors:
Tumors of orofacial nerves and their sheaths (neurofibroma, neurolemmoma, malignant schwannoma)
Cranial nerve tumors with orofacial affections (trigeminal neurinoma, acoustic neurinoma, and olfactory neuroblastoma)
Systemic tumors with significant neural and orofacial symptoms (multiple endocrine neoplasia)
Parkinson's disease:
presence of tremor - alleviates against effective oral hygiene and plaque control measures
Weakened swallowing capability can augment the risk of aspiration
levodopa - may begin to develop dyskinesias (chorea, dystonia), which can affect the jaw (orobuccal dyskinesias) as well as teeth grinding
dry mouth or xerostomia, masticatory difficulties
