Objective: To assess the possible risk factors that contribute to early dental implant failures in a teaching hospital. Materials and Methods: This cross sectional study evaluated past records of the 24 patients treated with 53 dental implants and were divided into two groups, one with failed dental implants before occlusal loading and the other with successful implants. Variables such as Age, gender, location of implants (maxilla or mandible), type of implant healing (single or double stage) and timing of implant placement (fresh extraction sockets or healed sites) were assessed. Results: About 4 (7.5%) out of 53 dental implants failed to osseointegrate before the prosthetic phase. The difference between the two groups was statistically significant p= 0.032 regarding the healing of dental implant (single or double stage), however, it was not significant in terms of age, gender, site and timing of implant p>0.05. Conclusion: Single stage implant surgery may be an important risk factor for early Implant failure however, more studies with larger sample size should be done to investigate risk factors that contribute to early failures.
Aim : To investigate the number and. patterns of. root canals. of mandibular. first. molars.. Methods.: Descriptive observational study to investigate the canal morphology using clearing technique. The duration of the study was one year from 1st February 2020 to 1st February 2021.Non purposive sampling technique was used and 200 mandibular first molar were collected. Data collected was analysed using the SPSS Vr 10. Study variables include Number and pattern of the roots in mandibular teeth. Descriptive statistics were used; frequencies of the root canals and their canal pattern were calculated. Results: In the mesial root, 14 teeth had a one root canal,186 possessed double root canals were observed. Distal root of 160 teeth possessed one canal, 40 teeth possessed two root canals with type 1 pattern mostly observed. Conclusion: Like other populations Pakistani population may have a diverse root canal system in the mandibular molars that ultimately affect endodontic therapy. Keywords: Roots, canals, anatomy, tooth clearing technique, demineralization
Aim. The study aimed to evaluate the root and canal system in maxillary 1st premolar teeth in our patients using cone-beam computed tomography in subpopulation of Pakistan in Lahore. Material & methods. This retrospective study in vivo assessed Cone Beam Computed Tomography (CBCT) imaginings of maxillary 1st premolars from February 2017 to January 2019. This study determined the number of roots, canals and root canal conformation as described by Vertucci’s classification. Results. 150 subjects aged 17-75 years were enrolled with 90 females and 60 males. From 200 1st maxillary pre-molars, 75% of the teeth had two roots. 21% had one root. 4% had three roots. 94% teeth had two canals. Three canals were detected in 4% teeth. One canal in 2% teeth. Regarding canal configuration, type I canal in 72% cases and type V canal in 13% of cases. Conclusion. The Cone-beam computed tomography system is par excellence diagnostic modality than radiographic diagnosis providing improved and exact knowledge of root and canal variations plus configuration. Keywords: CBCT, Maxillary premolars, Endodontic treatment, Vertucci’s classification, root canal.
