Gingival fibers attach to tooth cementum Ans✓✓✓gingiva
PDL fibers attach tooth cementum to Ans✓✓✓bone
The PDL is 0.2mm wide, but DECREASES in THICKNESS to 0.1mm
in older adults due
to the deposition of Ans✓✓✓cementum and bone
permenant tooth's CERVICAL LINE has the GREATEST
CURVATURE DEPTH on the Ans✓✓✓mesial
The GINGIVAL FIBERS (not PDL fibers) that extend inter-proximally
(tooth-to-tooth) over
the alveolar crest of bone and are embedded in the CEMENTUM of
adjacent teeth are Ans✓✓✓transseptetal fibers
The CREST of interdental bone should typically FOLLOW A
PARALLEL LINE BETWEEN Ans✓✓✓adjacent CEJ

THIRD that run from
,cementum OBLIQUELY to insert into bone CORONALLY are
Ans✓✓✓oblique fibers
The MAIN function of OBLIQUE FIBERS is to Ans✓✓✓provide tooth
support during function and
reduce and resist INSTRUSIVE and ROTATIONAL FORCES into the
alveolus
The two-dimensional ANTERIOR-POSTERIOR CURVATURE of the
MANDIBULAR
OCCLUSAL PLANE starting at the canine cusp tip, continuing through
all posterior buccal
cusp tips and anterior ramus, and ending at the mandibular condyle is the
Ans✓✓✓curve of spee

common in Class II,
division I malocclusion is Ans✓✓✓overjet
Average OVERJET is how many mm? Ans✓✓✓2-4mm
A patient whose mandibular incisors lie ANTERIOR to the maxillary
incisors best
describes Ans✓✓✓reverse overjet
,The VERTICAL overlap of maxillary anteriors over mandibular
anteriors common in Class
II, division II malocclusion is Ans✓✓✓overbite
A RETRUDED MANDIBLE with FLARING OF ALL MAXILLARY
ANTERIORS is
characteristic of Ans✓✓✓class II division 1 malocclusion
A skeletal malocclusion due to its RETROGNATHIC FACIAL
PROFILE positioning the
maxillary first molar's MB cusp tip to lie MESIAL to the MB groove of
the mandibular first
molar is a Ans✓✓✓class II malocclusion
A skeletal malocclusion due to its PROGNATHIC FACIAL PROFILE
where the mandibular
teeth are positioned mesial to the maxillary teeth and anterior may be in
crossbite or edgeto-
edge is a Ans✓✓✓class III malocclusion
A RETRUDED MANDIBLE with FLARING AND RETRUSION OF
SOME MAXILLARY
ANTERIORS best describes a Ans✓✓✓class II division II
malocclusion
, The maxillary first molar MB CUSP is directly above and aligns with
the MB GROOVE
of the mandibular first molar in a Ans✓✓✓class I occlusion
Lateral misalignment of the arches resulting in the BUCCAL positioning
of the mandibular
molars relative to the maxillary molars is Ans✓✓✓posterior crossbite
A WEDGE-SHAPED DEFECT along the gingival margin caused by
FLEXURE at the
CEMENTOENAMEL JUNTION (CEJ) during biting, chewing, or
grinding is Ans✓✓✓abfraction
The visible or palpable movement or VIBRATION of teeth (especially
incisors) during
normal occlusal contact/forces is Ans✓✓✓fremitus
Tooth movement caused by occlusal forces is Ans✓✓✓fremitus
The common CRACKLING sound in the TMJ caused by improper
movement of the
articular disc and mandibular condyle is Ans✓✓✓crepitus
