Introduction: Dental implants are now treatment of choice in replacing of missing teeth. Treatment outcomes with dental implants are predictable and favourable. Long term implant survival is dependent on proper implant planning and case selection. Precision in dental implant placement is the sine qua non for dental implant success. Radiographic examinations are the only non-invasive technique for visualizing the bone topography, volume and location of vital structures like mandibular canal and maxillary sinuses. In this study we have tried to evaluate commonly used radiographic modalities in implant planning, orthopantomograph (OPG) and computed tomography (CT) and tried to compare their accuracy with direct measurements with skull sectioning at predetermined maxillary first molar region. Materials and Methods: Ten dry human skulls were subjected to OPG, CT and skull sectioning respectively. Measurements on height and width of the alveolar bone were noted at the maxillary first molar region and results were compared. Results: The mean height of alveolar bone measured using OPG, CT and Skull sectioning was found to be 12mm, 9.4mm and 9.3mm respectively. The mean value of width of alveolar bone measured using CT and skull sectioning was found to be equal at 10.3mm. Additionally, the mean rate of magnification for OPG was found to be 40%, whereas for CT it was just 2%.

“…Of late, the cone beam CT has alleviated risk of radiation to a certain degree. 9 Orthopantamograph (OPG) is another imaging modality which is both inexpensive and also widely available. OPG causes much lower dose of radiation exposure than CT/ CBCT to the patients, thus making it a much safer option.…”

The objective of this study was to classify the morphology of bifid mandibular canals and to evaluate their relationship with the roots of third molars, using cone beam computed tomography (CBCT) scans. The CBCT scans of 75 patients were analyzed and the bifurcations were classified according to Langlais et al. (1985). The relationship of bifurcation and third molars was established according to the following classification: class A -uninvolved, class B -close relationship, class C -intimate relationship and class D -absence of third molars. Data were submitted to descriptive statistics, and the results indicated that the patients' mean age was 48.2 (± 13.2) years. Unilateral bifurcation (Type 1) was the most frequent type (72.6%), followed by unilateral Type 2 (19.3%). Class D was the most frequent (57.33%), followed by class C (21.33%), class B (13.33%) and class A (8%). It could be concluded that most cases presented unilateral bifid mandibular canals extending to the third molar or adjacent regions, and when present, the roots seemed to be a continuation of the bifid mandibular canal.

The aim of this study was to evaluate the accuracy of linear measurements made on conventional and digitized periapical and panoramic radiographic images of dry human hemi-mandibles. images from the posterior region of 22 dry human hemi-mandibles were obtained by conventional panoramic and periapical radiography technique. Using a digital caliper, 3 vertical measurements were marked directly on the dry hemi-mandibles (reference measurements) as well as on the tracing from the conventional radiographic images of the specimens made onto acetate paper sheet: Distance 1: between the upper limit of the alveolar ridge and the lower limit at the mandible base; Distance 2: between the upper limit of the alveolar ridge and the upper limit of the mandibular canal; Distance 3: between the lower limit of the mandibular canal and the lower limit of the mandible base. next, the radiographs were digitized and the three measurements were made on the digital images using UThSCSa image Tool software. Data were analyzed statistically by one-way ANOVA (α=0.05). There was no statistically significant differences (p>0.05) between periapical and panoramic radiographs or between the measurements recorded using the digital caliper and UThSCSa software compared with dry mandible specimens for Distances 1 (p=0.783), 2 (p=0.986) and 3 (p=0.129). In conclusion, the radiographic techniques evaluated in this study are reliable for vertical bone measurements on selected areas and the UThSCa image Tool software is an appropriate measurement method.
