Morphological variations of mandibular first premolar on cone-beam computed tomography in a Saudi Arabian sub-population.

ABSTRACT: In-depth knowledge of common and aberrant pulp morphology is essential for appropriate diagnosis and treatment planning prior to commencing root canal treatment. Radicular morphology of mandibular premolars has been extensively studied. Considerable variation in the number of canals and roots found in these teeth has been reported.

Aim

The purpose of this study is to investigate the root and root canal morphology of mandibular first premolar among Saudi Arabian subpopulation in Aseer using CBCT.

Methods

Cone-beam computed tomography images of Mandibular first premolar were taken from 166 patients which were referred to Armed Forces Hospitals Southern Region (AFHSR), Khamis Mushayt, Asir region Saudi Arabia. All the images were assessed by two Evaluators (An Endodontist and a Radiologist). Inter-examiner reliability was determined and was assessed by KAPPA value.

Results

The mandibular first premolar (n = 216) distributed as 120 teeth in female and 96 teeth in male. Out of the 120 teeth examined in female groups one canal was seen in 95 (79.2%) teeth, two canals in 19 (15.8%) teeth and three canals in 6 (5%) teeth where as in the Male group out of 96 teeth, 52 (54.1%) teeth showed one canal, 32 (33.3%) teeth with two canals whereas 12 (12.5%) teeth showed presence of three canals.Chi-Square test for mandibular first premolars demonstrated the chance of second canal in the mandibular first premolar more in male than female and these differences was statistically significant (P ? 0.05).

Conclusion

Endodontic therapy of mandibular premolars is a challenge for clinician because of their frequent morphological and anatomical abnormalities. Proper knowledge about number of root canals and canal configuration is a key to success in Endodontic. There is a great variability in different population regarding the root canal configuration in mandibular pre-molars. However, most studies state the mandibular first premolar has one root canal. Also, the most prevalent type of root canal found was Type I vertucci.

Project description:Background and objectives Analyzing the anatomical and morphometric information of the hard palate is crucial in prosthodontics, orthodontics, maxillofacial surgery, implant dentistry, and forensic anthropology. No data exist in the literature regarding the morphometric analysis of the hard palate using 3D imaging techniques in Saudi Arabia. Therefore, this study aimed to evaluate the dimensions and types of hard palates using 3D geometric morphometrics and the existence of gender-related differences in a selected Saudi population. Material and methods This cross-sectional study was performed by radiological evaluation of arbitrarily collected Cone Beam computed Tomography (CBCT) images includes 130 male and 45 female individuals from our department’s archives, radiology department, Dental Hospital, Qassim University. The Galileos® Comfort Plus System (Sirona 3D, Germany) was used to obtain the CBCT images while standardizing the parameters. Images were linearly measured using Galileos software. Measurements of palatal length, palatal breadth, and palatal height, as well as the calculation of the palatine index and palatal height index, were noted and statistically analyzed. Results The mean palatal length, breadth, height, palatine index, and height index were 48.8 ± 3.9 mm, 36.2 ± 3.8 mm, 11.6 ± 2.4 mm, 74.7 ± 8.9, and 32.4 ± 7.1, respectively. The mean palatal length, breadth, and height were greater in men than in women. The majority of the palatine index values corresponded to leptostaphyline (76.6%), followed by mesostaphylline (12%) and brachystaphylline (11.4%), distribution among males and females were not statistical significance (p > 0.05). Palatal height index analysis revealed that the majority were orthostaphyline (59.4%), followed by chamestaphyline (26.3%), and hypsistaphyline (14.3%) these distributions were not significant statistically among males and females(p > 0.05). Conclusion The palatine index and palatine height index are useful in prosthodontics, orthodontics, and forensic anthropology for identifying races on the basis of the skull.
