치아의 구조와 성분으로 알아보는 치아 시린이 치료!

치아가 시린이유는 무엇일까요?

시린이는 어떻게 치료할 수 있을까요?

치아가 시린이 이유를 이해하기 위해서는 치아의 구조와 성분을 이해해야합니다.

치아는 에나멜(법랑질), 덴틴(상아질), 신경(근관)으로 이루어져 있습니다.

치아의 주성분은 하이드록시아파타이트라는 미네랄입니다. 우리 뼈의 주성분과 같습니다.

치아가 시린이유는 상아질(덴틴)과 관련이 깊습니다.

상아질이 노출 되면 치아가 치아가 시리기 때문입니다.

Abstract

OBJECTIVES:

To evaluate the desensitizing effect of nano-hydroxyapatite (n-HAP) on dentine hypersensitivity (DH).

SOURCES:

Seven electronic databases were searched on April 27, 2018.

STUDY SELECTION:

Randomized clinical trials (RCTs) were included based on the PICO strategy: Participants - Humans with DH; Intervention - n-HAP-containing desensitizing; Comparison -n-HAP-free treatments or placebo/negative control; and Outcomes - relief of DH. The risk of bias was classified by the Cochrane guidelines. Five meta-analyses were performed to evaluate the efficacy of n-HAP with regard to pain assessment stimuli (primary outcome); comparison of n-HAP with other treatments or placebo/negative control, and effectiveness of at-home and in-office n-HAP use (secondary outcomes). The quality of the evidence was evaluated using the GRADE.

DATA:

Six RCTs with 4 weeks of follow-up were included in the meta-analysis. For the primary outcome, n-HAP showed a better desensitizing effect for evaporative stimuli (SMD -1.09 [-1.24, -0.94], p < 0.00001) and tactile stimuli (SMD -0.93 [-1.42, -0.43]) than other treatments (p = 0.0002). However, there was no difference between n-HAP and other treatments for the cold stimuli (SMD -0.17 [-0.81, 0.48], p = 0.61). In an overall analysis, n-HAP-containing treatment showing the most significant desensitizing effect (SMD -0.93 [-1.19, -0.68], p < 0.00001) with a high quality of evidence for pooled results. In the secondary outcomes, n-HAP showed the best effect in the overall analysis (p < 0.05) with moderate quality evidence.

CONCLUSIONS:

The n-HAP-containing treatment showed better clinical performance than other treatments for DH relief. However, long-term follow-up RCTs are required in the future before definitive recommendations can be made.

CLINICAL SIGNIFICANCE:

Dentin hypersensitivity is a common global condition and its multifactorial etiology has led to the development of several treatments. The n-HAP-containing treatment showed greater DH relief when compared to other desensitizing agents, placebo or negative control.
