Objectives: One of the economical ways of dental caries prevention is using fluoride containing toothpastes. For fluoride to be effective in toothpastes, significant amount of fluoride need to be in solution form. Global standard of fluoride content of toothpastes is 1500 ppm (part per million).This study aimed to determine fluoride content of some special toothpastes. Methods : This research was cross-sectional and laboratory study. In this study five brands of different toothpastes including: Crest, Sensodyne, Colgate, Unique, Beam were provided and total fluoride of each was determined using ion-selection method and then the fluoride content of each brand compared to the global standard amount. The data was analyzed byone sample t-test at 0.05 level of significance. Results: Sensodyne had 735 ppm, Beam got 76.12, Colgate got 1195 ppm, Unique got 426 ppm and lastly Crest had 1605.70 amount of fluoride in their composition. Quantitative analysis indicated total fluoride content of Sensodyne ,Beam, Unique were significantly below global standard at 0.05 level (p<0.05) in terms of fluoride content whereas total fluoride content of Crest and Colgate had no significant difference with global standard (p<0.05). Conclusion : The results showed that Crest and Colgate met the standard of global fluoride content

Acupuncture is one of the best known complementary therapies in Traditional Chinese medicine and has a history of more than 2500 years. Acupuncture stimulates the nervous system and shifts the perception of pain signals and also releases natural painkillers, such as endorphins and serotonin.
Aim: Main aim of this article is to review related articles that have focused on acupuncture and its applications in dentistry. The other objective is to maintain a quick sketch of acupuncture use in dentistry for dental clinicians and to encourage them to use acupuncture with the knowledge of its advantages and disadvantagesDental clinicians have to be familiar with the applications of acupuncture for dental disorders because its successful use for dental conditions has been proven.
A detailed search was performed to identify systematic reviews and research/original and review articles, using PUBMED, EBSCO, GOOGLE SCHOLAR and CDSR from 1990 to 2017 in both languages English and Persian to clarify the application of acupuncture in dentistry.
Various studies have shown that acupuncture can be used to manage wide range of disorders in dentistry such as dental pain, altering pain threshold, myofascial pain, temporomandibular disorders, gag reflex, dental anxiety, chronic muscle pain or spasm, TMD , Atypical facial pain, Headache (tension headache, migraine), (dry mouth), Nerve pain (neuralgia, especially trigeminal neuralgia, neuropathic pain, nerve injury), Paresthesia or anesthesia of the oral and perioral structures. However acupuncture's ability as dental analgesia or controlling post operative pain after dental surgery as a single therapy is questionable.
On the systemic review of acupuncture-associated articles in Cochrane library, previously effective acupuncture therapy lacks adequate evidences, which may be related to the low quality of randomized controlled trials (RCTs) in this context.
