“…The facial gingivae are mostly affected although the palatal and lingual gingivae are also involved in severe cases [33,48,49]. The site of lichenoid lesions is generally similar to that of OLP [6,7], manifesting respectively on the buccal mucosa and the lateral border of the tongue [17,19] followed by the gingiva, the lips, the floor of the mouth, and the palate [6,22]. Lichenoid lesions have several features: 1) In the lesions related to dental restorations, there is direct or close contact with the agent, usually in the posterior buccal mucosa and the lateral border of the tongue [22,23,42].…”

“…In another study, an increased number of granulated mast cells in the basal membrane degeneration regions, hyper-vascularization, and increased thickness of the Periodic acid-Schiff (PAS) positive basal membrane have been cited [26,72]. Although some researchers still believe that OLP and oral lichenoid lesions are histopathologically non-differentiable, their distinguishing characteristics have been stated to be very clear [11,14,17,21,25]. By investigating all of the proposed differentiating characteristics, the following points are stated as the features that histopathologically differentiate OLP lesions and oral lichenoid reactions: 1.…”

“…Agha-Hosseini et al [80] showed P53 deficiency in the saliva among OLP patients with squamous cell carcinoma (SCC). The prevalence of malignant transformation in lichenoid reactions is more than that in OLP and is reported to be about 0.5% to 6.5% [17]. The process of malignant transformation of oral lichenoid reactions is attributed to the phenomenon of field cancerization, in which all related events expose these patients to a higher risk of multiple primary malignancies in the oral cavity [11,76].…”

“…In 1986, Lind et al used the term LR (lichenoid reaction) for clinical lesions related to amalgam restorations, which clinically established the causal relationship [14]. Unlike OLP, which has a single title, lichenoid reactions have been listed with different terms in the review of articles based on various etiopathogeneses according to the frequency of repetition, as follows: OLR (Oral Lichenoid Reaction) [5,11,14,15,[17][18][19][20][21][22][23][24][25][26]. OLL (Oral Lichenoid Lesions) [6,8,15,16,22,23,[25][26][27].…”

Background and Aim: Oral lichen planus (OLP) is a chronic, inflammatory, T-cellmediated autoimmune oral mucosal disease. Oral lichenoid lesions develop as a type IV hypersensitivity reaction. Both of these entities are potential precancerous conditions; this adds to their clinical significance. The purpose of this literature review was to detect the similarities and the differences of these lesions to enhance the information of colleagues in managing these groups of patients. Materials and Methods: For this review, we searched Cochrane, Medline, and Embase databases from January 1990 to the end of October 2018. A total of 96 published papers, including review papers, case reports, cohort studies, case-control studies, and meta-analysis studies, were included and analyzed. Results: OLP and oral lichenoid reactions are two distinct diseases. They can be clinically similar but they have different etiologic factors. A histopathological study is necessary to differentiate them. Conclusion: The definitive diagnosis of these conditions is extremely important given their potentially premalignant nature. A timely diagnosis probably results in proper management. Based on the present research, the final differentiation between OLP and oral Lichenoid reactions relies on both clinical and histopathological manifestations according to the modified World Health Organization (WHO) criteria.

“…The lesions are often located close to the implant and may be reticular, atrophic, erosive, or plaque-like in form [10]. Dental amalgams containing mercury and gold have long been shown to have an association with lichenoid contact reactions [151,152], although some studies and case reports link OLLs to other metals such as copper [153], chromate, thimerosal (mercurial) [151], nickel [154,155], and palladium [155]. Of note, the onset of allergic contact dermatitis seems to require prolonged intimate contact between the oral mucosa and the eliciting agent over a period of years; in addition, the mean age of patients with OLL was 54.6 years in one study [156,157].…”

Hypersensitivity Reactions to Implanted Metal Devices: Facts and Fictions

The use of metals in the medical field has become increasingly prevalent over the past few decades. Patients find themselves being exposed to metals in a variety of ways, ranging from external exposure to instruments such as the stainless steel in surgical blades to internal exposure via medical devices being implanted in their bodies. There has been growing interest in the possibility of developing hypersensitivity reactions to constituent metals in medical implant devices, both in cutaneous and systemic forms. Hypersensitivity reactions to metals are uncommon, but they are reported and require appropriate evaluation and management, particularly if they are symptomatic. In view of the lack of consensus in the field on the appropriate steps to evaluate and manage patients with suspected metal hypersensitivity reactions, this review aims to analyze current evidence on hypersensitivity reactions to metallic implants in orthopedic surgery, endovascular surgery, obstetrics and gynecology, and dental surgery. Key words: Metal hypersensitivity. Metallic implants. ResumenEl empleo de metales dentro de la medicina ha ido aumentando de forma progresiva en las últimas décadas. Los pacientes se exponen a metales de diferentes formas desde fuentes externas, como instrumental quirúrgico como el presente en las hojas de acero de los bisturíes, hasta implantes metálicos. Como consecuencia de ello se está produciendo un interés creciente por la posibilidad de desarrollar reacciones de hipersensibilidad a metales presentes en los materiales y objetos implantados, tanto en forma de reacciones cutáneas como sistémicas. Las reacciones de hipersensibilidad a metales no son frecuentes, pero pueden desarrollarse, y por ello, requieren de un diagnóstico y tratamiento adecuado, especialmente en aquellos pacientes que desarrollen síntomas. No existe un consenso en el proceso diagnóstico ni en el tratamiento de estas reacciones en los pacientes con sospecha de alergia a metales. Esta revisión tiene por objeto actualizar la evidencia existente sobre las reacciones de hipersensibilidad a implantes metálicos en cirugía ortopédica, cirugía endovascular, cirugía obstétrica y ginecológica (OB-GYN) así como la dental. Palabras clave: Hipersensibilidad a metales. Implantes metálicos.

The availability of adhesive primers capable of bonding chemically to base metal alloys without well defined passive oxide surface film has been improved significantly over the last decade. Therefore, the purpose of the study was to compare and evaluate the effect of metal primer on adhesion of heat cure acrylic resin to cast titanium. Shear bond strength test was conducted on 80 commercially pure titanium cast metal heat-cure acrylic resin discs treated with different surface treatments. The first group received no surface treatment (group I); the second group was subjected to sandblasting (group II); the third group was treated with bonding agent (alloy primer) (group III) and the fourth was treated with sandblasting and alloy primer (group IV). After the samples were surface treated, acrylic resin was mixed, packed and processed over the test area of cast titanium. Ten specimens of each group were immersed in distilled water for 24 h followed by thermocycling for 20,000 cycles. Shear bond-strength between the heat cure acrylic resin and titanium was evaluated using Instron universal testing machine. Debonded specimens of all the groups were subjected to SEM analysis. The bond failure (MPa) was analyzed by ANOVA and Duncan's multiple comparison tests. Surface treatment with sandblasting, followed by the application of alloy primer showed maximum shear bond strength before and after thermocycling (24.50 ± 0.59 and 17.39 ± 1.56 MPa respectively).The bond strength values are found to be in decreasing magnitudes as group IV > group III > group II > group I. The following pretreatment to improve the shear bond strength of heat cure acrylic resin to titanium is recommended in order to attain the maximum bond strength in cast titanium frameworks for various prostheses: sandblasting, cleaning in an ultrasonic bath for 10 min and air drying followed by application of a bonding agent uniformly on the sandblasted cast titanium surface before packing with heat cure acrylic resin.
