Should deciduous teeth be preserved in adult patients? How about stem cells? Is it reasonable to preserve them?

Abstract

When seeking orthodontic treatment, many adolescents and adult patients present with deciduous teeth. Naturally, deciduous teeth will inevitably undergo exfoliation at the expected time or at a later time. Apoptosis is the biological trigger of root resorption. In adult patients, deciduous teeth should not be preserved, as they promote: infraocclusion, traumatic occlusion, occlusal trauma, diastemata and size as well as morphology discrepancy malocclusion. Orthodontic movement speeds root resorption up, and so do restoring or recontouring deciduous teeth in order to establish esthetics and function. Deciduous teeth cells are dying as a result of apoptosis, and their regeneration potential, which allows them to act as stem cells, is limited. On the contrary, adult teeth cells have a greater proliferative potential. All kinds of stem cell therapies are laboratory investigative non authorized trials.

Tomographic characterization of the Gubernacular Canal in the eruption of second and third molars

“…3 The remains of the cell organize themselves in laments, from the reduced epithelium in the enamel to the oral mucosa, forming the gubernacular cord, and the presence of chemical mediators in this cord enables the activation of osteoclasts that begin to act, hindering the ossi cation of this cord, maintaining only a surrounding bone cortical which will result in the true gubernacular canal, 4 which will in turn be responsible for guiding the coronary portion to the most occlusal region of the alveolar process. 5,2 There are many complications that can occur during a tooth's eruption process. Among these are such anomalies as inclusion and dental impaction, which are routine situations in dental clinical practice and which present a certain potential to generate other problems associated with them, such as the development of pathological conditions, like cysts and tumors, tooth reabsorptions, pericoronitis, among others.…”

Comparative Evaluation of Bond Strength of Different Luting Cements for Cementation of Stainless Steel Bands on Primary Molar Crowns (Stainless Steel and Zirconia Crowns): An In Vitro Study

“…The best, natural, and conservative way to avoid these problems is to preserve the primary teeth in the arch till their normal time of exfoliation is attained. 3 Justifiably, it is rightly quoted that primary teeth serve as the best space maintainers for permanent dentition. However, if premature extraction or loss of a tooth is unavoidable the safest option to maintain arch space is by placing a space maintainer, either a fixed or a removable one.…”
