시린이, 상아질지각과민 케어~

치아가 시린 이유와 관리 방법

 

치아가 시린 이유는 상아질이 노출 되기 때문입니다.

상아질은 법랑질에 둘러싸여 외부로 노출 되지 않는 치아의 내부 조직입니다.

여러 원인에 의해서 상아질이 노출되면 상아질의 상아세관(작은 구멍)이 노출되어 시리다고 느끼게 됩니다.

 

상아질이 노출 되는 이유

탈회 충치등으로 인한 에나멜질의 파괴

잇몸질환으로 인한 치아뿌리 상아질 노출(잇몸퇴축)

충치치료를 위한 에나멜질 상아질 삭제

치아미백으로 인한 치면과 상아질 부식

스켈링 등으로 인한 근면 노출부위의 세척 및 자극

 

시린이를 관리하는 방법

노출된 상아세관을 막고 코팅하면 외부의 자극이 차단되어 시린증상이 완화되게 됩니다. 그러나 이 코팅이나 막이 사라지면 다시 시리다고 느끼게 되므로 장기적으로는 상아질을 에나멜질화 해야합니다.

상아질을 에나멜질화 하는 방법은 치아에 필요한 미네랄을 꾸준히 공급하는 것입니다.

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.

Keywords: Clinical trials; Dentin hypersensitivity; Desensitizing agents; Meta-analysis.
