The prevalence of radix molaris in the mandibular first molars of a Saudi subpopulation based on cone-beam computed tomography

OBJECTIVES@#The purpose of this study was to determine the incidence of radix molaris (RM) (entomolaris and paramolaris) in the mandibular first permanent molars of a sample Saudi Arabian subpopulation using cone-beam computed tomography (CBCT).@*MATERIALS AND METHODS@#A total of 884 CBCT images of 427 male and 457 female Saudi citizens (age 16 to 70 years) were collected from the radiology department archives of 4 dental centers. A total of 450 CBCT images of 741 mature mandibular first molars that met the inclusion criteria were reviewed. The images were viewed at high resolution by 3 examiners and were analyzed with Planmeca Romexis software (version 5.2).@*RESULTS@#Thirty-three (4.5%) mandibular first permanent molars had RM, mostly on the distal side. The incidence of radix entomolaris (EM) was 4.3%, while that of radix paramolaris was 0.3%. The RM roots had one canal and occurred more unilaterally. No significant difference in root configuration was found between males and females (p > 0.05). Types I and III EM root canal configurations were most common, while type B was the only RP configuration observed.@*CONCLUSIONS@#The incidence of RM in the mandibular first molars of this Saudi subpopulation was 4.5%. Identification of the supernumerary root can avoid missing the canal associated with the root during root canal treatment.

Perianal paget's disease

We report a rare case of Perianal Paget's disease. It presents with non-specific anal symptoms. The treatment of choice of Perianal Paget's disease is surgical excision. This patients due to refusal of any surgical intervention, managed successfully with radiotherapy. The patient had an eventful recovery after this conservative method

Gastrointestinal bezoar - case reports and literature review

Gastrointestinal bezoars are conglomerates of fiber or undigested material in the astrointestinal tract. Phytobezoar or plant bezoar is comparable to fruits and vegetables in its composition [composed of cellulose, lignin, and hemicellulose]1. These could be found in the stomach, small intestine, cecum, or esophagus
