It is important to take into account variations in structures related to dental pulp for planning the most adequate endodontic treatment management. The objective of this study was to determine the morphology of roots and canals of maxillary first premolars (MFPs) using cone-beam computed tomography (CBCT). This retrospective study included a sample of 392 CBCTs of Peruvian adults proportionally selected by sex, age, and quadrant.

Xenogeneic collagen matrix vs. connective tissue graft for the treatment of multiple gingival recession: a systematic review and meta-analysis.

The aim of this systematic review (SR) compared the effect of xenogeneic collagen matrix (XCM) vs. connective tissue graft (CTG) for the treatment of multiple gingival recession (MGR) Miller Class I and II or Cairo type I. Five databases were searched up to August 2022 for randomized clinical trials (RCTs) comparing the clinical effects of XCM vs.

How efficacious is the combination of substitute bone graft with autogenous bone graft in comparison with substitute bone graft alone in the horizontal bone gain? A systematic review and meta-analysis.

Background: A systematic review (SR) was conducted to answer the following focused question based on PICO strategy: In patients who were submitted to horizontal guided bone regeneration, "how efficacious is the combination of substitute bone graft with autogenous bone graft in comparison with substitute bone graft alone, in terms of bone gain?"

Material And Methods: MEDLINE (PubMed), Scopus, Embase, Web of Science databases were searched, and hand searches were made up to June 2021, to find randomized clinical trials comparing the clinical effects of autogenous bone graft + substitute bone graft versus substitute bone graft alone in the treatment of horizontal guided bone regeneration.

Results: Four trials representing 109 individuals were included. All studies included in this SR used allogeneic bone graft.

Dentigerous cyst and the importance of early detection. report of a pediatric case.

Dentigerous cysts are a common cystic pathology that develop between the first and third decade of life and are mainly associated with impacted or erupted mandibular third molars followed by maxillary canines and maxillary third molars. These kinds of cysts are the result of the proliferation of enamel epithelium after its formation, the pathogenesis of which is not clear. Few of these cysts have been reported in pediatric patients.

Concrescence in anterior teeth assessed by cone beam computed tomography. A case report.

Dental concrescence is an anomaly in which the cementum overlying the roots joins, causing the union of two different teeth. It is often reported in posterior dentition, affecting certain dental procedures such as root canal treatment, periodontal procedures, orthodontic movement and dental extraction. This case report describes the successful diagnosis and treatment of a 20-year-old male with a moderate skeletal class II who was referred for a radiographic evaluation after 1 year of failed orthodontic movement of teeth 1.

Level of patient comfort and measurement reproducibility of three different probes: A cross-sectional study.

Objective: To determine the comfort level and reproducibility assessment of the probing pocket depth obtained with three different probes.

Methods: A cross-sectional clinical study was conducted in accordance with the STROBE standards. Three different types of periodontal probes were selected: (1) University of North Carolina (UNC) probe, (2) World health organization (WHO) probe and (3) UNC12 COLORVUE probe.

Clinical and Histological Manifestations of Chronic Coca Leaf Chewing in a Peruvian Population: A Cross-sectional Study.

Aims: This study aimed to determine the possible clinical and histological periodontal effects of long-term coca leaf chewing habit in habitants of the highland region of Peru.

Materials And Methods: A total of 100 residents, were recruited for the study. Fifty individuals were habitual coca leaf chewers and 50 were non-users.

Semi-longitudinal Study of the Mcnamara Cephalometric Triangle in Class II and Class III Subjects Grouped by Cervical Vertebrae Maturation Stage.

The aim was to compare the McNamara cephalometric triangle values in untreated normodivergent Class II and Class III malocclusion subjects of Latin American origin grouped by cervical vertebrae maturation stage to an untreated Class I malocclusion normodivergent control group. The study was conducted on a sample of 610 pretreatment lateral cephalograms (250 male, 360 female), examined and grouped according to their anteroposterior skeletal relationship (Class I, II or III), cervical vertebrae maturation stage (Pre Pubertal Peak P1 = CS1 and CS2, Pubertal Peak P2= CS3 and CS4, and Post Pubertal Peak P3 = CS5 and CS6) and sex. Co-A, Co-Gn and ENA-Me were measured in each lateral cephalogram.
