My apologies for the malformed table. I have corrected the formatting and expanded it to include every condition mentioned in your provided files, with as much detail on aetiology and statistics as available in the documents.
Comprehensive Table of Oral and Maxillofacial Conditions
| Condition | Aetiology | Statistics (Prevalence, Ratios, etc.) |
|---|---|---|
| Cleft Lip and Palate | Failure of fusion of adjacent embryological processes. Influenced by both inheritance and environmental factors (drug/alcohol abuse, cigarette smoke, insecticides, microorganisms). | Occurs in 1/700 births among Caucasians, 4/700 in Native Americans, 2/700 in Japanese, and 0.3/700 in African Americans. Cleft lip +/- palate is more common in males; cleft palate alone is more common in females. |
| Bifid Uvula / Bifid Tongue | Incomplete fusion of the embryonic processes that form them. A bifid uvula is often a sign of a palatal cleft. Artificial bifid tongue can occur as a complication of tongue piercing. | Not specified. |
| Lip Pits | Congenital sac-like invaginations of lip mucosa. | Depth ranges from 1 to 4 mm. |
| Double Lip | A rare anomaly characterized by an excess fold of tissue on the inner aspect of the lip, most commonly the upper lip. | Not specified. |
| Aglossia / Microglossia | Aglossia is the partial or complete absence of the tongue due to failure of fusion of branchial arches. Microglossia is an abnormally small tongue from a lack of development of the tuberculum impar. | Microglossia is a rare congenital disorder. |
| Ankyloglossia (Tongue Tie) | Attachment of the anterior tongue to the floor of the mouth by a tight frenum. | Not specified. |
| Macroglossia | Abnormal increase in tongue size; may be congenital (e.g., Down syndrome) or from neoplasia. | Not specified. |
| Fissured Tongue | Deep grooves are present on the dorsum of the tongue. | Prevalence is 5%. The lecturer noted it is very common, found in 20-30% of the population. |
| Lingual Thyroid (Ectopic Thyroid) | Normal thyroid tissue remains at the foramen caecum on the dorsum of the tongue. | Presents as a mucosal-coloured round nodule, up to 4 cm in diameter. |
| Lingual Varicosities | Swollen, twisted veins on the ventral surface of the tongue. | More common in older individuals; rare in children and adolescents. |
| White Sponge Nevus | A persistent lesion, noted in the first two decades of life, caused by a genetic mutation in specific cytokeratins. | Not specified. |
| Fordyce Granules | Ectopic sebaceous glands in the oral mucosa, considered a normal anatomical variation. | Present in 60% to 80% of the adult population. Appear as 1- to 3-mm yellowish papules. |

| Morsicatio (buccarum, linguarum, labiorum) | Frictional keratosis caused by habitual chewing/nibbling of the cheek, tongue, or lip. | Not specified. |
| Snuff Dipper’s Keratosis | Develops in users of smokeless tobacco where the tobacco directly contacts the tissues. | Not specified. |
| Amalgam Tattoo | Accidental implantation of dental amalgam within oral tissues during dental procedures. | Not specified. |
| Smoker’s Melanosis | Excessive melanin pigmentation thought to be a protective mechanism against toxins and heat from smoking. | Found in the gingiva of about 20% of smokers; more frequent in females. |
| Nicotinic Stomatitis | Occurs in smokers from exposure of the palate to smoke and heat of burning tobacco. | Not specified. |
| Pyogenic Granuloma | Exuberant overgrowth of granulation tissue in response to minor chronic irritation. | Not specified. |
| Traumatic Fibroma | A reactive lesion of dense, highly fibrous connective tissue from persistent chronic irritation. | Not specified. |
| Drug-Induced Gingival Hyperplasia | A reactive phenomenon in patients taking medications that stimulate collagen growth (e.g., Phenytoin, Cyclosporine, Nifedipine). | Not specified. |
| Dental Caries | Multifactorial disease requiring a susceptible host, cariogenic microorganisms, fermentable carbohydrates, and time. | The most common disease in humans. |
| Acute Pericoronitis | Localized soft tissue infection associated with erupting teeth, commonly lower third molars. Microflora includes Actinomyces oris, Eikenella corrodens, Fusobacterium nucleatum, etc.. | Not specified. |
| Alveolar Osteitis (Dry Socket) | A painful complication of extractions due to the loss of the blood clot in the socket. | Occurs in 1-2% of extractions, more frequently after lower-third molar extractions. |
| Acute/Chronic Osteomyelitis | Infection of dental origin spreading through medullary bone. Predisposing conditions include radiation damage, osteosclerosis, diabetes, and smoking. | Almost all cases affect the mandible. Adult males are most affected. |
| Focal Sclerosing Osteomyelitis | Bony reaction to low-grade periapical infection from a non-vital tooth. | Affects children and young adults in the premolar or molar region of the mandible. |
| Oral Actinomycosis | A chronic, suppurative infection caused by Actinomyces israelii, a Gram-positive bacterium. | Rare. Half of all cases affect the face and neck. Men between 30 and 60 years are predominantly affected. |

I hope this revised and more detailed table meets your needs. Would you like me to add a “Clinical Features” column to this table for even more detail?
