Implants failures related to endodontic treatment. An observational retrospective study.

Objective: The aim of the study was to analyze potential etiological risk factors that constitute a complex problem in the clinical management of peri-implantitis.

Materials And Methods: An observational retrospective study was conducted to describe the possible effect of lesions of origin pulpar and/or periapical success or failure of the implant. The sample consisted of review of 800 implants, of which 500 were conducted at the Faculty of Dentistry of the UANL and 300 private clinics of Maxillofacial surgeons experienced in the placement of those who reside in Monterrey, Mexico.

Long-term follow-up and tomographic assessment of an intrabony defect treated with enamel matrix derivative.

Background: Enamel matrix derivative (EMD) has an extensive documentation of use in the treatment of periodontal defects. Digital volume tomography (DVT) has been in use in dental medicine since the late 1990s, with a major advantage of decreased radiation and cost-effectiveness compared to conventional computed tomography (CT). To the best of our knowledge, there is no peer-reviewed report documenting long-term tomographic assessment of an intrabony defect treated with EMD alone.

Breast cancer related proteins are present in saliva and are modulated secondary to ductal carcinoma in situ of the breast.

Objective: The objective of this study was to determine if protein-by-products secondary to cancer related oncogenes appear in the saliva of breast cancer patients.

Methods: Three pooled (n = 10 subjects/pool) stimulated whole saliva specimens from women were analyzed. One pooled specimen was from healthy women, another pooled specimen from women diagnosed with a benign breast tumor and the other one pooled specimen was from women diagnosed with ductal carcinoma in situ (DCIS).

Effect of abutment angulation on the strain on the bone around an implant in the anterior maxilla: a finite element study.

Statement Of Problem: Angled abutments are often used to restore dental implants placed in the anterior maxilla due to esthetic or spatial needs. The effect of abutment angulation on bone strain is unknown.

Purpose: The purpose of the current study was to measure and compare the strain distribution on the bone around an implant in the anterior maxilla using 2 different abutments by means of finite element analysis.
