Methamphethamine (TIK) is a highly addictive drug that acts as a stimulant for the central nervous system. It increases wakefulness and physical activity and can cause cardiac dysrhythmias, hypertension, hallucinations and violent behavior. Dental patients abusing methamphetamine often present with poor oral hygiene, xerostomia, rampant caries ("meth mouth") and excessive tooth wear. Management of these conditions is often challenging. A 24-year-old Caucasian man presented with severe dental pain, halitosis and self-reported poor dental appearance. A comprehensive examination including his medical history, panoramic radiographs and extra- and intraoral examination revealed 19 carious and erosive lesions. He reported using methamphetamine for eleven years and had not experienced much caries prior to using the drug. The patient's medical and dental histories along with radiographic and clinical findings led to a diagnosis of "meth mouth." Although various dental treatment options were offered to the patient, he opted for extraction of the most painful teeth in the left lower madibular quadrant and has yet to return for further treatment. This literature review and clinical case description of the oral manifestations of "meth mouth" is intended to alert dental practitioners to recognize and manage patients who are abusing methamphetamines. They should also be aware that these patients are often unreliable at following prevention advice as well as keeping follow-up appointments.

Structural changes in symbiotic human microorganisms can affect host phenotype. Liver-fire hyperactivity syndrome (LFHS) presents as bitter taste, halitosis, xerostomia, odontalgia, and other oral symptoms. LFHS is associated with hypertension (EH). In this study, tongue flora was analyzed to further understand the intrinsic relationship between tongue flora and LFHS. Samples of tongue coating, from 16 patients with EH-LFHS, 16 with EH-non-LFHS, and 16 controls, were obtained; then, 16S rRNA variable (V3-V4) regions were amplified and sequenced by MiSeq PE300 Sequencing. Tag clustering and Operational Taxonomic Units (OTUs) abundance analysis were used to compare the OTU sequence with the 16S database. The species were classified, and diversity and structure of the bacterial flora were compared between the three groups. Alpha diversity analysis, including Observed Species index and Chao index, indicated significantly higher richness of species in patients with EH-LFHS (p < 0.05). Higher phylogenetic diversity, in patients with EH-non-LFHS, indicates greater differences in evolutionary history than in patients with EH-LFHS. Streptococcus, Rothia, Neisseria, and Sphingomonas were the most prevalent in patients with EH-LFHS, differed from the other two groups. This indicates that richer bacterial diversity, and structure associated with EH-LFHS, may affect the occurrence, development, and outcome of hypertension and syndrome subtypes recognized by TCM.
