Occurrence of Dental Injuries and Periodontal Complications in Tongue-piercing Jewellery Users.

PURPOSE: Tongue piercing (TP) has been gaining in popularity, mainly among adolescents and young adults, and there has been a corresponding increase in reports of dental injury and adverse effects on periodontal tissue due to TP jewellery. The purpose of this study was to assess the type and prevalence of dental injury and periodontal complications in a group of Slovenian adolescents and young adults with TP in comparison with a control group. MATERIALS AND METHODS: This case-control study included 17 subjects with TP (study group) and 28 subjects without TP (control group). Subjects were clinically examined for dental injuries, as classified according to Andreasen. Periodontal complications were evaluated using an estimation of clinical attachment loss (CAL) and gingival recession (GR). Differences in categorical variables were analyzed using the chi-squared or Fisher's exact test as appropriate. Differences between the groups in numerical variables were analyzed with the Mann-Whitney U-test. A multiple logistic regression model was built to test the association between dental injuries and TP when controlling for cofounders, namely age and gender of study participants. The significance level was set at α = 0.05 (two-tailed). RESULTS: Subjects with TP had 12.2 higher odds of dental injury (CI = 2.2-67.7, p = 0.004) compared with subjects without TP. Enamel fractures were more prevalent in the study group (p = 0.002). Frequencies of other dental injuries in the two groups were similar. GR was significantly associated with TP (p = 0.008), while differences in CAL between the groups were not statistically significant. CONCLUSION: Subjects with tongue piercing had more dental injuries and gingival recession.

Tooth Decorations and Modifications ­ Current Trends and Clinical Implications.

Since earliest times, humans have felt the need to modify and beautify their bodies. Adornments in the form of tooth decorations have featured around the world for generations and continue to evolve. This paper describes current and forthcoming trends. It explores the use of tooth jewels, 'dental grills' and tooth tattoos which are not yet common in the UK, but are currently trending in the United States of America. This article reviews the literature and aims to describe the clinical effects each tooth decoration has on the dentition, along with appropriate management strategies. Owing to the lack of good quality studies, it is difficult to determine accurate effects on the dentition, but dental practitioners should focus on conservative and preventive management strategies. Clinical relevance: This paper describes modern day tooth decorations, explores the possible effects on oral health and suggests management strategies.

Jewellery: alloy composition and release of nickel, cobalt and lead assessed with the EU synthetic sweat method.

BACKGROUND: Several studies have shown nickel and cobalt release from jewellery by using spot tests, but the metal composition of jewellery is largely unknown. OBJECTIVES: To evaluate the metal composition of a large worldwide sample of mainly inexpensive jewellery items, and investigate the release of nickel, cobalt and lead from a subsample by using EN 1811:1998-required methods. METHODS: A total of 956 metallic jewellery components were examined with X-ray fluorescence spectroscopy. A subsample of 96 jewellery items purchased in the United States were investigated for nickel, cobalt and lead release by the use of artificial sweat immersion and plasma optical emission spectroscopy. RESULTS: Eighteen elements were detected. The 10 most frequently occurring were, in order of frequency, copper, iron, zinc, nickel, silver, chromium, tin, manganese, lead, and cobalt. Release of nickel was noted from 79 of the 96 US samples (0.01-98 µg/cm(2) /week), release of cobalt from 35 samples (0.02-0.5 µg/cm(2) /week), and release of lead from 37 samples (0.03-2718 µg/cm(2) /week). CONCLUSIONS: We present here a comprehensive list of the most frequently encountered metals in jewellery and fashion accessories. Different allergenic and non-allergenic metals are utilized. We also report the frequent release of nickel, cobalt and lead from these objects, despite legislative restrictions.

Usage test with palladium-coated earrings in patients with contact allergy to palladium and nickel.

BACKGROUND: Since the EU Nickel Directive came into force, concern has been raised that palladium may increasingly replace nickel in alloys used in jewellery and dentistry, and that it may cause as many allergy problems as nickel. OBJECTIVES: (i) To investigate the clinical relevance of contact allergy to palladium resulting from the wearing of palladium-coated earrings, and (ii) to evaluate the concordance in test results between palladium chloride (PdCl2 ), sodium tetrachloropalladate (Na2 PdCl4 ), and nickel(II) sulfate hexahydrate (NiSO4 .6H2 O), as well as variability in patch test reactivity. MATERIALS/METHODS: Forty female patients with pierced earlobes and previously known contact allergy to palladium and nickel were patch tested with dilution series of nickel and palladium salts. They wore earrings covered with palladium and titanium for 9 weeks to monitor the appearance of any clinical manifestations. RESULT/CONCLUSION: There is a low risk of eczema in palladium-allergic and nickel-allergic individuals when they wear jewellery coated with pure palladium, but further studies are needed to determine whether palladium, when present in alloys, could cause allergic reactions. PdCl2 , like NiSO4 .6H2 O, shows variability in patch test reactivity over time. Furthermore, Na2 PdCl4 seems to be a more sensitive test substance than PdCl2 for the detection of palladium allergy.

A study on the transfer of heavy methals released by Chinese commercial products.

OBJECTIVES: Studies by The World trade Organization (WTO) and the Organization for the Economic Cooperation and Development (OECD) state that the trade on counterfeit goods corresponds to 10% of the global trade and it is worth 450 billion dollars. In this work we studied the transfer of toxic metals released by some Chinese watches causing significant allergic dermatitis. METHODS: Several samples of dust released from metal parts got collected. Such powders were observed at the Electron Microscope complete with EDAX spectrometer. RESULTS: In all the studied dust samples we identified the following chemical elements: Cu, Ni and Zn. The SEM analysis has identified two predominant phases such as pure nickel and brass alloy (Cu-Zn). CONCLUSIONS: The first metal subjected to cession and to corrosion phenomena is nickel. The main causes of corrosion in the studied materials were due to the presence of chloride ions. Among the ceased metals found in our study nickel is the most dangerous. Scientific evidence now agree that nickel and certain nickel compounds are toxic and highly harmful to human health they indeed cause allergic contact dermatitis (DAC).

Oral piercing injuries treated in United States emergency departments, 2002-2008.

PURPOSE: The purpose of this study was to report the epidemiology and clinical history of oral piercing injuries presenting to US hospital emergency departments (EDs). METHODS: A retrospective analysis of oral piercing injuries was performed using patient injury data collected from 2002 through 2008 using the National Electronic Injury Surveillance System (NEISS) of the US Consumer Product Safety Commission. National estimates of ED visits were analyzed by injury type, anatomic site, and mechanism of injury according to age, gender, and race. RESULTS: An estimated 24,459 oral piercing injuries presented to US EDs during the 7-year period. The male:female ratio for ED visits was 1:2.6. Patients 14- to 22-years-old accounted for 73% of the ED visits. Injuries to the lips (46%), tongue (42%), and teeth (10%) predominated. Infections (42%) and soft tissue puncture wounds (29%) caused injury most commonly. Thirty-nine percent of ED visits resulted from patients' inability to remove mucosally overgrown oral piercings. Hospitalization was rarely required (<1%). CONCLUSIONS: Oral piercing injuries treated in US hospital emergency departments are most prevalent in teenagers and young adults. National data indicates that dentists working in emergency departments should be prepared to manage oral hard and soft tissue complications caused by oral piercings.

The use of dental drill in removing entrapped finger by metal ring in emergency department.

Ring removal is indicated in a number of clinical circumstances to manage or prevent tourniquet effect of the digit. A ring made from hardened metal may defy commonly known methods of removal. We reported a case of unusual difficulty in removing a ring of hardened metal composition using a dental drill. We believed the unusual circumstances of this case is likely to be repeated in some other clinical practice and this instrument is an appropriate option to consider in such cases.

[Oral jewelry: a review]. / Schmuck im Mundbereich: eine Ubersicht.

Oral jewelry is popular. One of the most widely spread types are so-called tooth diamonds made of composite materials which are applied to the teeth with an adhesive. Note that parents are required to sign a release form for under-aged patients in Switzerland. Tooth cap grills and gold teeth are considered status symbols within the Hip-Hop fashion scene. However, tooth ornaments favour the accumulation of plaque and can diminish the ability to articulate. With respect to jewelry in oral soft tissue especially tongue and lip piercings are of significance to dentists. Besides the systemic complications, which are mostly caused by a lack of hygiene or the failure of noting medical contraindications by the piercer, local complications occur frequently. After surgery, pain, swelling, infections as well as hemorrhages or hematomas can be observed. Long-term effects can be problematic: gingival recession can be discernes mainly in the case of lip piercings the loss of hard tooth substance in the case of tongue piercings. Because of that, conservation therapies can become indespensable. Patients wearing dental jewelry have to be aware of risks of tooth damage, and they regularly have to undergo dental check-ups. Information campaigns--for dentists as well as patients--are necessary.

[Children should always be examined upon suspicion of the ingestion of foreign bodies].

This case report is of a four-year-old otherwise healthy girl, who was presented to an ear, nose and throat department with salivation and suspected ingestion of a metallic pendant while falling asleep. An X-ray of the chest and upper neck confirmed the suspicion showing an approximately 2 × 2 cm foreign body shaped as a star located in the throat. In general anaesthesia, a metal necklace pendant was removed from the oesophagus mouth. The patient was released from hospital the day after surgery.

Amber necklaces: reasons for use and awareness of risk associated with bacterial colonisation.

Parents are increasingly placing amber necklaces on their infants or toddlers to prevent teething pain. The use of the necklaces can pose a risk of death by strangulation, however, there are no data on the potential infectious risk linked to bacterial colonisation associated with the necklaces. We aimed to analyse bacterial colonisation of amber necklaces worn by children during hospital consultations. This prospective observational study included all children wearing a teething necklace at consultation in the Paediatric Dermatology and the Paediatric Emergency Department of our hospital from April to December 2014. The study included 27 children (median age: 10.7 months; 70.4% female). The surface of necklaces underwent bacteriological analyses using three different agar cultures. Parents completed a brief questionnaire to provide reasons for using necklaces and express awareness of risks. One child had a history of impetigo. All necklaces were colonised by bacteria (median: four species per necklace [range: 1-9]); 32 different species were found, the most frequent being coagulase-negative staphylococci (Staphylococcus epidermidis in 88.9% of cases). In three cases, methicillin-sensitive Staphylococcus aureus was found. The most frequent reason for wearing a necklace was to prevent teething pain (n = 17; 63.0%); the necklace was judged effective (moderately/highly effective) in 74.1% of cases, however, 70.4% of parents considered the use of the necklace to be risky. Amber necklaces may be highly colonised by commensal germs of the skin, mainly coagulase-negative staphylococci. Although these bacteria are saprophytes, they may become pathogenic in particular conditions.

Tooth jewelry in an 8 year old child: case report.

PURPOSE: The number of perioral/oral body modifications has been increasing over the previous 30 years. The dental impact upon adults and adolescents has been documented previously. The purpose of this case study was to report the dental impact of a child's self-reported tooth decoration. The study is a case report of an 8-year old child who reported for dental care with discomfort in the mandibular left second primary molar. She embedded a stick-on rhinestone stud into the tooth for aesthetics. It fractured the tooth and led to its loss. Anticipatory guidance about perioral/oral body modification risks to children, as well as to adolescents and adults, should be included in the discussion of interventions that influence oral wellness.
