Some items may also be useful in other species.
Abbreviations to be used in case logs are shown in (blue brackets)
Infundibulum (INF): Enamel cup-like infolding from the occlusal surface in incisors (one) and maxillary cheek teeth (two)
Diastema (D): Space between teeth in a jaw.
Pulp horn (PH): An elongation of the pulp chamber extending towards the cusps of brachyodont teeth; an elongation of the common pulp chamber extending towards the occlusal surface of equine cheek teeth (numbers refer to the Du Toit numbering system, e.g., PH1, PH2, etc.).
Regular secondary dentin: Dentin produced on the periphery of the pulp after the tooth has come into occlusion which gradually reduces the size of the pulp horns
Irregular secondary dentin: Physiological dentin that is laid down last, sub-occlusally in the center of the pulp horn which prevents pulp exposure with normal tooth wear
Sinus (SIN): Paranasal cavity within a bone
Conchofrontal sinus (SIN/CF): Compound term for the frontal sinus and the dorsal conchal sinus, which are continuous in equines
Caudal maxillary sinus (SIN/CMX): Cavity in equines separated by the maxillary septum from the rostral maxillary sinus; communicating with the frontal and sphenopalatine sinuses
Rostral maxillary sinus (SIN/RMX): Cavity in equines separated by the maxillary septum from the caudal maxillary sinus; opening freely into the ventral conchal sinus
Sphenopalatine sinus (SIN/SP): Continued cavity formed by the sphenoid and palatine sinuses in equines; opening into the caudal maxillary sinus
Ventral conchal sinus (SIN/VC): Cavity enclosed by the caudal part of the ventral concha.
Tooth elongation (T/EL): Abnormal intraoral and/or periapical extension of the coronal and/or apical portion of the tooth
Open diastema (D/O): Pathological widening of the interproximal space that has similar widths at the gingival margin and occlusal surface
Valve diastema (D/V): Pathological widening of the interproximal space that is considerably wider at the gingival margin than at the occlusal surface
Temporal teratoma (TT): Vestigial dental structure in the vicinity of the temporal bone as a result of failure of closure of the first branchial cleft usually associated with swelling or a sinus tract at the base of the pinna of the ear; also known as heterotopic polyodontia or “ear tooth” and erroneously called dentigerous cyst in the horse
Pulp horn defect (PH/D): Pulp horn exposure or defective secondary dentin overlying a pulp horn noted on the occlusal surface of cheek teeth which may or may not be vital
Infundibular caries (CA/INF): Caries of the maxillary cheek teeth infundibulae; grade 1 involving cementum only; grade 2 also involving enamel; grade 3 also involving dentin; grade 4 affecting the structural integrity of the tooth; use CA/INF/D for distal infundibular caries and CA/INF/M for mesial infundibular caries
Peripheral caries (CA/PER): - Caries affecting the periphery of the cheek teeth; grade 1 involving cementum only; grade 2 also involving enamel; grade 3 also involving dentin; grade 4 affecting the structural integrity of the tooth
Shear mouth (SHE): Abnormally increased occlusal angulation of the cheek teeth; for example >40° for mandibular cheek teeth and >25° for maxillary cheek teeth
Sinusitis (SIN/IN): Inflammation of the sinus (e.g. SIN/IN/RMX = rostral maxillary sinusitis)
Primary sinusitis: Inflammation of the sinus associated with bacterial infection of the sinuses without any detectable predisposing cause.
Secondary sinusitis: Inflammation of the sinus associated with bacterial infection where a predisposing cause such as periapical disease or intra-sinus growth is present
Dental sinusitis: Sinusitis caused by periapical disease of the caudal cheek teeth
Diastema odontoplasty (or widening) (D/ODY): Removal of interproximal dental tissue to avoid entrapment of food between teeth
Sinoscopy (SIN/EN): Endoscopic examination of the sinus using a trephine portal
Sinus flap (SIN/F): Surgical access to the sinus via a skin and bone flap; use SIN/CF/F for a chonchofrontal sinus flap and SIN/MX/F for a maxillary sinus flap
Sinus lavage (SIN/LAV): Flushing of the sinus
Trephination (TRP): Surgical access to a structure of interest via skin incision and removal of a circular piece of bone using a trephine
Sinus trephination (SIN/TRP): Access to the sinus via a trephined hole
Closed extraction with odontoplasty (XS/ODY): Removal of interproximal crown tissue to facilitate transoral extraction of a tooth
Extraction of a tooth after apicoectomy and repulsion (XSS/APX/RPL): Extraction of a tooth after apicoectomy and repulsion which is performed via TRP, SIN/TRP or SIN/F
Transbuccal extraction (XSS/BUC): Extraction of a tooth after buccotomy
Transbuccal extraction with alveolectomy (XSS/BUC/ALV): Extraction of a tooth after buccotomy and alveolectomy
Transcommissural extraction (XSS/COM): Extraction of a tooth after commissurotomy
Transcommissural extraction with alveolectomy (XSS/COM/ALV): Extraction of a tooth after commissurotomy and alveolectomy
Minimally invasive buccotomy extraction (XSS/MIB): Extraction of a tooth via minimally invasive buccotomy (small incision made for introduction of straight instrumentation to elevate, section or drill into a cheek tooth for the purpose of facilitating its transoral extraction)
Extraction via repulsion (XSS/RPL): Extraction of a tooth after repulsion which is performed via TRP, SIN/TRP or SIN/F
