Radiographic Interpretation of Periodontal DiseasesHadi Munib
Periodontal diseases are classified as gingival diseases or periodontitis. Gingival diseases include plaque-induced and non-plaque induced inflammation, with plaque-associated gingivitis being more common. Periodontitis is primarily classified by clinical presentation into chronic, aggressive, or as a manifestation of systemic disease. Radiographs provide a two-dimensional view that can show early bone loss signs like rounding of the alveolar crest but have limitations and do not replace a clinical exam. Successful periodontal therapy can halt and potentially reverse bone loss, while periodontal changes may also be associated with conditions like squamous cell carcinoma or lichen planus.
This case report describes a pyogenic granuloma lesion in a 30-year-old female patient. She presented with a 3-month history of a painless gingival swelling interfering with eating and speaking. Clinical examination revealed an oval-shaped, erythematous nodule measuring 0.7 cm. Histopathological examination showed numerous blood vessels with extravasated red blood cells within the connective tissue, along with inflammatory cells. This was consistent with a diagnosis of pyogenic granuloma. The lesion was surgically excised. Pyogenic granuloma is a common gingival growth considered to be an exaggerated response to minor trauma or irritation.
This presentation covers routinely used intraoral & extraoral plain radiographs used in assessment of maxillofacial trauma patients with extended coverage on occlusal radiographs. This PPT is echanced with addition of images for all radiographs
This document discusses fractures of the zygoma bone. It begins with an introduction and overview of fracture patterns, classification, clinical features, investigations, management approaches, reduction techniques, fixation methods, and complications. Key points include that zygoma fractures often involve adjacent structures like the maxilla and orbit. Fracture lines typically extend from the inferior orbital fissure in three directions. Clinical features may include facial deformity, diplopia, and neurological symptoms. Investigations include radiography and CT scanning. Surgical approaches to reduction include temporal, intraoral, and endoscopic methods. Fixation often utilizes miniplates applied at one to four points depending on the fracture pattern and displacement.
Dental diagnosticians are responsible for detecting salivary gland disorders using applicable imaging techniques. Salivary gland disorders can be inflammatory, non-inflammatory, or space-occupying masses. Clinical signs may include swelling, pain, altered salivary flow, and a review of medical history. Diagnostic imaging is used to differentiate inflammatory from neoplastic processes, identify sialoliths, and determine tumor location and characteristics. Common imaging modalities discussed include plain radiography, sialography, CT, MRI, scintigraphy, and ultrasonography.

1. CHIRURGIA DELLE
SALIVARI:
FACIALE AMICO E GUIDA
ANTONIO POLITI
Orl e chirurgia cervico facciale ad indirizzo oncologico - Taormina
2. La chirurgia delle salivari, in particolare sulla parotidea
è spesso causa di frustrazioni e fastidi per l’intimo
rapporto con il faciale poiché accanto alla radicalità
oncologica va rispettata l’esigenza estetico - funzionale
3. E’ chirurgia di pertinenza esclusiva ORL
poiché solo questo specialista possiede nel
suo bagaglio culturale chirurgico, e nel
temperamento, nozioni di:
Oncologia cervico faciale
Chirurgia estetica
Microchirurgia
4. Se altri specialisti - senza bagaglio culturale,
chirurgico e tecnologico - si cimentano, possono
essere tacciati di appropriazione indebita
Fermiamo le mani non abilitate!!
5. La patologia parotidea colpisce
tutte le età e i due sessi
casistica degli ultimi 10 anni (circa 396 casi)
TUMORI BENIGNI (88% casi)
57% tumore misto
32% cistoadenolinfoma
1% oncocitoma
TUMORI MALIGNI (12% casi)
37% muco – epidermoide
32% adenocarcinomi
10% k adenoido cistico
10% carcinoma squamoso
7% carcinoma a cellule aciniche
2% linfomi
1% melanomi
?? k ex adenoma pleomorfo ??!!
TUMORI DI ALTRE SEDI
INFILTRANTI LA PAROTIDE
6. Le neoplasie delle
ghiandole
sottomandibolari, meno
frequenti, hanno però
maggiore incidenza
maligna (20%), mentre
rarissime sono le
neoplasie delle
sottolinguali, e quasi
sempre maligne.
8. IL TRATTAMENTO CHIRURGICO
ATTUATO è STATO DI:
Enucleazione
Enucleoresezione
Parotidectomia preneurale
Parotidectomia totale conservativa
Parotidectomia radicale
Tipi di intervento eseguiti sulle aree cervicali:
Svuotamento conservativo
Svuotamento radicale
( 6 casi con lembo muscolo/cutaneo del gran pettorale
4 casi con lembi di rotazione)
9. Se lo conosci lo eviti!
… se non ci fosse, la chirurgia cervico
faciale sarebbe più facile… meno
scariche di adrenalina… ma quanta
noia!!
E’ sempre prevedibile !!
10. Al suo emergere dal forame
stilomastoideo può avere delle varianti
Nel 71% è biforcato
triforcato
Più raramente è pluriforcato
a ventaglio
12. Anche se non c’è un vero piano di clivaggio, il tessuto
ghiandolare non aderisce al nervo.
I suoi rami periferici decorrono sempre su un piano
parallelelo al lobo superficiale
Ha un diametro di circa 2-3 mm color bianco argenteo
(il microscopio lo magnifica)
L’arteria carotide esterna decorre in un piano profondo
rispetto al nervo
La vena giugulare esterna passa di norma al di sotto
del nervo
Talvolta, ma
raramente,
la vena
passa sopra
il VII
13. L’enucleazione favorisce lo sgranamento della
neoplasia, con alto rischio di residuo di malattia,
rottura della fragile pseudocapsula ed
insemensamento (pseudopodia), recidiva o
multifocalità.
14. Il ramo labiale è infatti
intollerante allo stiramento ed
alla compressione, il più delle
volte il deficit è parziale e
reversibile
Raramente si ha un deficit delle
attività muscolari volontarie
(pulizia dai residui alimentari
del vestibolo buccale,
incontinenza per i liquidi dalla
commissura labiale…)
La branca intermedia ha un più
precoce ritorno alla
funzionalità normale, poiché
molto arborizzata e ricca di
anastomosi
La lesione più
frequente
riguarda il ramo
mentoniero
33. A pieno titolo, pertanto, il faciale è chiave di volta ed
alleato della chirurgia otologica e parotidea, così come
lo spinale lo è per il collo, ed il ricorrente per la tiroide
