ABSTRACT
La exposición de dentina radicular asociada a una recesión gingival puede producir dolor ante distintos estímulos, situación que puede difi cultar la vida cotidiana de los pacientes que lo padecen, además de presentar complicaciones estéticas que pueden afectar la autoestima. La hipersensibilidad dentinaria tiene una etiología asociada a múltiples factores, siendo el principal factor de riesgo la recesión gingival, situación clínica común que se observa en gran parte de la población. El propósito de esta revisión es reunir distintos conceptos que expliquen la asociación que mantienen estas dos patologías, sus etiologías, el cuadro clínico que presenta la hipersensibilidad dentinaria para poder realizar un diagnóstico diferencial y las distintas opciones de tratamiento para realizar un adecuado manejo de esta condición que incluyen desde recursos terapéuticos que buscan resolver la sintomatología hasta procedimientos quirúrgicos que resultan más invasivos y que se enfocan en tratar el factor predisponente como es la recesión gingival misma (AU)
Dentin exposure level periodontal tissues can cause pain to diff erent stimuli, a situation which can hinder the daily lives of patients who suff er, in addition to having aesthetic complications that can damage self-esteem. Dental hypersensitivity has a multifactorial etiology associated being the main risk factor gingival recession, the common clinical situation observed in much of the population. The purpose of this review is to bring together various concepts that explain the association that maintain these two pathologies, their etiologies, clinical picture presented dentine hypersensitivity to perform a diff erential diagnosis and treatment options for proper management of this condition ranging from therapeutic procedure seeking to resolve the symptoms to surgical procedures that are more invasive and that focus on treating the predisposing factor such as the gingival recession itself (AU)

OBJECTIVE: To provide evidence from a clinical viewpoint that the bacteria persisting within the root canal system do not have a significant impact on the treatment outcome as long as an adequate apical sealing is performed. METHODS: A total of 42 patients with pulp necrosis and a periapical index (PAI) score of 5. Root canal treatment was performed in which the root canal filling was limited to the apical third of the root. In the control group, the root canal filling was performed up to the canal orifice. Data were analyzed using the Mann-Whitney test and the χ2 or the Fisher exact test (when appropriate). RESULTS: All cases presented clinical success, absence of pain, swelling, sinus tract, tenderness to palpation or percussion and presented normal tooth mobility. Fifteen months were enough for all cases of both groups to be classified with a PAI score of ≤2. There was no statistical difference between the cases that ended the study with a PAI-1 or PAI-2 score. CONCLUSION: Within the limitations of this study, no significant differences in healing rates after complete obturation or only apical third obturation were observed. An adequate apical sealing can improve periapi-cal healing, thus intracanal remnant bacteria apparently have no significant impact, at least for the first 15 months of follow-up.
