LUC & LUP3: this is a small left maxillary fragment that contains the nearly complete, albeit [walaupun, sekalipun] etched [tergores] canine & anterior premolar. The alveolar bone that partially encloses the roots of the teeth lingual is heavily eroded & only small segments of the external alveolar surfaces are preserved between the roots of the LUC & LUP3 & anterior to the LUC root. The LUC crown & root are intact, although the root has been cracked [retak, rekah]; the LUP3 crown has lost a substantial [banyak] portion of enamel from the distobuccal aspect & the apex of the distobuccal root is missing.

LUC: occlusal wear is moderate w/ the apex considerably reduced in height; a large, long dentine island is exposed in the centre of the cusp, which displays a distolingual wear bevel [miring]. The mesial ICF is small & flat; distally there was moderate attrition w/ premolar, although the crowns are now separated.

Viewed occlusally, the crown present a broadly triangular outline. The buccal face tapers [meruncingkan, melancipkan] cervically & faint [lemah, redup] traces of the mesiobuccal & distobuccal grooves are discernible. The lingual face [permukaan] presents a moderately well-developed & symmetrically disposed cervical prominence. A broad, well-developed ridge rises from it to pass [melewati] just distal to the middle of the crown. The moderate distal marginal ridge is partially separated from the cervical eminence by a shallow fissure that continues cervically from the deep, albeit [walaupun] narrow grove between the distal marginal & ‘median’ ridges. The mesial marginal ridge is not as well developed as the distal & a narrow fissure [celah, retak] separates it from the lingual face of the main cusp.

The root is straight & robust; it is ovoid in cross-section. The exposed mesial face shows a broad, shallow, vertical furrow [alur, galur, parit, kerunyut]. The root measures 23.5mm in length & the MD & BL diameters at the cervix are 6.3mm & 9.2mm respectively.

MD meas: 9.7 MD est.: 10.1 BL meas: 9.7



S7-45 [p.85] [11dec12Sl]
RC sup (Pl2, Fig.28a-c). This a very nearly complete crown w/ approximately two-thirds of the root. Crown damage is restricted to the loss of an enamel chip from the buccal surface near the apex.

Occlusal wear is moderate, w/ the crown tip reduced to a flat surface w/ a distal bevel. A long thin dentine strip is exposed in the middle of this facet. The mesial ICF is small & concave & it’s restricted to the buccal side of the mesial face. The distal ICF is larger & it’s located over the lingual side of the distal face.

Viewed occlusally, the crown has an ovoid outline. The buccal face presents a broad, tapered appearance w/ rounded mesio & distocervical corners. The distal moiety [bagian, separuh] of the buccal face is flattened & along the distal border a slight marginal ridge is perceptible [jelas, nampak]. Perikymata & hypoplastic pitting are evident on the buccal face. Lingually, the cervical enamel prominence is well-developed; it supports two well-developed marginal ridges arise from its mesial & distal ends. The centre of the cervical eminence is shallowly incised & a slight furrow is present where the mesial marginal ridge joins the cervical eminence. A low tubercle is partially demarcated between these two fissures. The lingual face of the crown possesses no median ridge; thus, a moderate degree of shoveling is expressed.

The preserved portion of the root is vertically inclined & robust; it measures 6.4 MD & 9.0 BL ate the cervix. The mesial face of the root possesses a broad furrow that courses upwards from the level of the cervical enamel margin.

MD meas: 9.7 MD est.: 10.0 BL meas: 10.0

FS 7-3c: right UM2 [22may07Sl vbm & 7jan14Sl vbm]
It is a complete RUM2 crown w/ a tiny [mungil] piece of the buccal side of the root neck preserved.

Occlusal wear slight; the cusps have been reuced to nearly the same plane. The protocone & hypocone are more heavily worn [usang, lecek] than the lingual cusps; the protocone, which evinces [menunjukan dg jelas, memperlihatkan, show] a minuscule [amat kecil, very small] dentine exposure [kedapatan], is the only cusp on which dentine is exposed [menampakan]. The mesial & distal faces present large, BL elongate [memanjangkan] & flattened ICFs.

Viewed occlusally, the crown possesses a nearly square outline, w/ the BL diameter across the mesial cusps greater than across the distal cusps due to a slight reduction in the buccal extent of the metacone. All principal cusps are well-developed; the protocone is the largest, followed by the paracone, metacone & hypocone in diminishing (decreasing) order of size. Wear [pemakaian] has obliterated [menghilangkan, melenyapkan] most of the morphological detail from the mesial portion of the occlusal surface; a short, transverse [melintang]fissure mesial to the paracone represents the remnant [bekas, sisa] of the anterior fovea. The distal trigon crest (dtc) is thick, & it appears to have been complete [lengkap]. The talon basin is represented by an elongate & narrow, transverse [melintang] groove [galur, lekuk] that is completely [sama sekali, habis2an] enclosed [menyertakan, mengurung, melingkungi] distally by a moderately thick distal marginal ridge (dmr).

The buccal groove is not discernible [kelihatan, dpt dilihat], & the protocone is worn [lusuh, usang] such that it is not possible to ascertain [memastikan, meyakinkan] whether the CT was present.

MD meas= 11.3mm; MD est= 11.6mm; BL meas= 12.5mm

S7-89: RUM2 [p.91] [7jan14Sl vbm]
This is a beautifully preserved [menjaga, memelihara], complete crown w/ a very short segment of root. There is slight damage to the mesial enamel cervix & vertical crack [retak, celah] passes through the distobuccal face of the metacone.

Occlusal wear is slight; large enamel facets are developed on the protocone, hypocone & paracone. The lingual cusps have been reduced to a flat horizontal plane, but dentine is not exposed. The mesial ICF is a flattened ovoid in the center of the face; the smaller distal ICF is located over the lingual half of the distal surface.

Viewed occlusally, the crown has an ovo-trapezoidal outline w/ a reduced distobuccal corner. All four principal cusps are present; the protocone is the largest, followed by the slightly sub equal paracone, hypocone & metacone. The mesial marginal ridge is moderately thick & complete. The fovea anterior is in the form of a sinusoidal transverse fissure. The moderate distal trigon crest appears to have been complete; these short incision [irisan, potongan, torehan] is present on its distal aspect. The distal marginal ridge is moderately thick & complete but very short. The fovea posterior is represented by a moderate pit.

The buccal groove takes the form of a short, shallow depression. Lingually there is no trace of the carabelli feature, although this may have been lost [ks.hilang] to wear

MD meas= 10.9mm; MD est= (11.2mm); BL meas= 12.5mm
