Panoramic radiographs revealed the loss of trabecular structure and a ground-glass appearance between the right first incisor and second molar
This can be achieved by placing the anterior portion of the detector no further forward than the distal portion of the second premolar or by centering the second molar
on the receptor.
Pulpectomy followed by stainless steel crown restorations were done for left deciduous second molar
and right deciduous first and second molars
Terminal plane relationship of the second primary molars was evaluated and recorded as class 1: the distal surfaces of maxillary and mandibular primary second molars
lie in the same vertical plan; class 2: the distal surface of the mandibular primary second molar
is posterior to that of maxillary primary second molar
; and class 3: the distal surface of the mandibular primary second molar
is anterior to that of the maxillary primary second molar
In a study by Lo and Moyers,14 the most favorable sequence of eruption to obtain a normal molar relationship was as follows: first molar, central incisor, lateral incisor, first premolar, second premolar, canine, second molar
in the maxilla and first molar, cen- tral incisor, lateral incisor, canine, first premolar, second premolar, second molar
in the mandible.
2) The reason for these extractions is the high incidence of impaction, often associated with a number of oral problems, such as pericoronitis, periodontal defects in the distal region of the second molar
, caries in the third or second molars
, different types of odontogenic cysts and tumors, and crowding of the lower incisors.

The ratio between heavy and light strontium isotopes increases slightly towards the crown of the second molar
and decreases towards the top of the third molar.
Manipulation of an external light source helped to manifest the microwear scars on the paracone of the second molar
Complex odontomas are usually located in the first and second molar
areas of the mandible or the anterior maxilla?
The depth of the von spee's curve was calculated on lateral cephalograms as perpendicular distance from tip of lower central incisor to the mandibular plane (L1-MP), distobuccal cusp tip of the lower second molar
(M7-MP) to the mandibular plane, the deepest point of the von spee's curve to the mandibular plane (S-MP), and proportioned with each other.
