Introduction

Globally, estimates show that 34 million people are livingwith the human immunodeficiency virus (HIV), including3.3 million children under the age of 15 [1•, 2•]. Of all newHIV infections among adults and children in 2011, 71 %

were from sub-Saharan Africa, totaling 90 % of prevalenceworldwide [1•, 2•]. In 2010, African Americans comprised12 % of the U.S. population but represented 44 % of newHIV infections [3]. Hispanic Americans were also dispro-portionately affected; although they made up only 16 % ofthe total U.S. population in 2010, they accounted for 21 %of new HIV infections that year [3]. In the U.S., the minorityof HIV cases are among children—a mere 15 of the 32,052cases in 2011 [2•].

The epidemiologic profile of early childhood caries(ECC), the single most common infectious, yet highly pre-ventable, disease among children, is very similar in HIV-infected and uninfected children. While there is evidenceindicating a global decline in caries for adults and olderchildren, it has increased in children under 5 years of age[4] primarily due to the lack of introduction of early andongoing effective interventions including systemic and top-ical fluorides, sealants, improved diet, oral health education,and dental care—all interventions highly endorsed by theAmerican Academy of Pediatricians (AAP) and theAmerican Academy of Pediatric Dentists (AAPD) [5, 6•].However, despite these improvements, ECC remains themost prevalent oral disease in much of Asia, Africa, andLatin America. In the U.S., it affects 60 %–90 % of children[7••], with children from poor homes twice as likely to beaffected by ECC when compared with their more affluentpeers. Furthermore, these low income, underserved childrenalso have a higher risk of not seeing a dentist or of receivingany disease treatment [8].

Oral Health Manifestations of HIV

Oral lesions are among the earliest and most common clin-ical signs of HIV among children and adults [9–11](Table 1). For effective management, early diagnosis andgood oral health and hygiene are paramount. Along with athorough medical/dental history, detection of oral lesions

continues to be a low cost mechanism for diagnosing andtracking HIV [9, 12••]. Modeled after categories created bythe European Community (EC) Clearinghouse on OralProblems Related to HIV Infection and the World HealthOrganization (WHO) Collaborating Centre on OralManifestations of the Human Immunodeficiency Virus, orallesions for children are grouped as: (1) lesions commonlyassociated with pediatric HIV infection, (2) lesions lesscommonly associated with pediatric HIV infection, and (3)lesions strongly associated with HIV infection but rare inchildren [12••, 13].

Overall, oral candidiasis (OC) is the most common orallesion and often the first clinical manifestation in childrenwith HIV [9]. Oral diseases categorized by the above systeminclude: Group 1—OC, herpes simplex virus, linear gingivalerythema (LGE), parotid enlargement, recurrent aphthousulcers; Group 2—necrotizing stomatitis, necrotizing periodon-tal disease, human papillomavirus (HPV), xerostomia; Group3—Kaposi’s sarcoma (KS), non-Hodgkin’s lymphoma (NHL),and oral hairy leukoplakia (OHL) [12••, 14••].

Oral candidiasis often presents as 1 of the following 3types. The first type, pseudomembranous candidiasis, ischaracterized by non-adherent, creamy white plaques thatare wiped off easily to reveal underlying redness (Fig. 1).Erythematous candidiasis has flat, red patches showingmostly on the palate and top of the tongue, sometimesaccompanied by non-adherent filmy white plaques and/ortenderness and burning. Angular cheilitis displays as red orulcerated fissures radiating from the corners of the mouth,sometimes accompanied by red papules and/or OC, andoften causing pain (Fig. 2). Angular cheilitis has causesother than candida albicans, including infection fromStaphylococcus aureus or β-hemolytic streptococci or sim-ply recurrent dry skin or irritation from slobber due topacifier use. When diagnosing angular cheilitis, it is impor-tant to take a thorough medical history, and when possible, aculture to determine the cause and consequently right courseof treatment. Children with herpes simplex virus have afever, swollen, and tender lymph nodes, and lesions insideand around the mouth and lips that often ulcerate (Fig. 3).One of the most common forms of periodontal diseaseamong HIV-infected children, LGE, shows up as bands ofredness and/or lesions on the gums, particularly at the baseof the teeth, often accompanied by bleeding upon brushing.Parotid enlargement results in facial swelling and disfigure-ment and may cause pain or be seen with lymphoid intersti-tial pneumonitis (Fig. 4). Apthous ulcers range in size from5 mm (minor apthous ulcers) to 2 cm (major) and have a redborderline; major ulcers are often accompanied by pain andmay interfere with eating and speaking (Fig. 5).

Of the oral lesions in Group 2, ulcers that may eat awayat the oral mucosa to the bone are characteristic of necrotiz-ing stomatitis. Similarly, necrotizing periodontal disease

causes tissue death. Necrotizing ulcerative gingivitis specif-ically eats away at the gingiva and may exhibit sloughingwith red, swollen, or sometimes yellowish-gray tissue andbleeding (Fig. 6). Necrotizing ulcerative periodontitis, how-ever, destroys tissue beyond the gingiva and may also causebleeding and pain, or in extreme cases, expose the jawbone.HPV can cause flesh-colored warts to erupt. Xerostomia is acondition where salivary flow rate is dramatically reducedor the consistency of saliva changed, resulting in dry mouth.Xerostomia commonly increases the thickness of saliva andmay lead to increased thirst, difficulty swallowing, mouthsoreness, halitosis, and dry, cracked lips as well increasedoral disease (Fig. 7).

Group 3 lesions are not often present in children, but mayoccur. Both KS and NHL are cancers associated with HIV.KS can cause lesions across the body (including inside themouth) and may range in color (often red or violet) andmorphology. NHL can cause symptoms such as fever, fa-tigue, and rash, along with swelling of the lymph nodes;however, it can also produce lesions on the body includingin the oral cavity. OHL consists of white lesions with cor-rugated surfaces commonly on the sides of the tongue.

Impact of Antiretroviral Treatment on Oral Health

Even when children are being treated for HIV with HAART,orofacial lesions may still present. But, the prevalence oflesions ranges from 31.4 % to 87.2 % depending on whetheror not and using which drug combination they are treated forHIV [15–17]. One study established an oral lesion preva-lence of 57.5 % in children treated with HAART [18].Another reported that, for children on HAART, 2.9 %presented with oral candidiasis, 2.9 % linear gingival ery-thema, 2 % bilateral parotid enlargement, and 1 % enlargedcervical lymph nodes [19]. However, other studies found nosignificant difference in HIV-related oral lesions in childrenon HAART compared with children not on therapy [20, 21].

Antiretroviral use has also been associated with softtissue lesions. For example, non-reverse transcriptase inhib-itors (NRTIs) have been linked to intra-oral ulcers in 3 %–30 % of patients receiving zalcitabine (ddC), mucocutane-ous hyperpigmentation in patients on zidovudine (AZT),and xerostomia in 30 % of patients taking didanosine (ddI)[22–25]. Xerostomia and/or oral ulcerations can also be seenin 7 % of patients taking protease inhibitors [26]. Otheradverse events include taste abnormalities in 20 % of patients,circumoral paraesthesia in a quarter of patients receivingritonavir, parotid lipomatosis or facial lipoatrophy (as a featureof generalized lipodystrophy) in patients receiving ritonavir,cheilitis in 57 % of patients taking indinavir, and erythemamultiforme with nevirapine treatment [27–32]. Although thisfinding has been inconsistent, long-term use of HAART

has also been connected with osteoporosis or osteodystrophywith implications for alveolar bone loss or periodontal disease[33, 34]. Similarly, HAART-induced diabetes mellitus anddyslipidemia may predispose patients to periodontal diseasein the long term [35, 36].

A disproportionate increase in the incidence and preva-lence of neoplasms from the persistent dysregulation of theimmune system has been hypothesized [37, 38]. In addition,a consistent observation has been an increase in benignHPV-associated oral neoplastic lesions (i.e., papillomas,condylomas, and focal epithelial hyperplasia) in patientson HAART [39–41]. This raises the possibility of an in-creased incidence of HPV-related oral malignancies withlong-term HAART, particularly if the HPV subtypes carriedare high-risk subtypes (such as HPV-16).

HIV and Hard Tissue Disorders

Nutrition has long been recognized to be important foroptimal growth and development [42]. HIV infection isknown to have a direct effect on worsening a child’s nutri-tional status, with protein-energy malnutrition being a majornutritional problem and a common complication of HIVinfection [43–45]. HIV infection, therefore, has a potentialimpact on the timing of tooth emergence due to its directinfluence on nutrition and growth. HAART also has the

potential to impact the formation of the teeth. In HIV infec-tion, there is a dysregulation of calcium homeostasis, whichresults in excessive increases of intracellular calcium in-duced by HIV viral proteins [46, 47]. Calcium is importantfor both tooth formation and tooth maturation and, thus,HIV infection may have a potential effect on tooth structureformation.

In addition, results suggest that COUP-TF interactingprotein 2 (Ctip2) functions as a critical regulator of epithelialcell fate and differentiation during tooth morphogenesis[48]. Tooth disruption has been demonstrated in Ctip2-/-

mice [48]. However, others have suggested that Ctip2 actu-ally recruits chromatin-modifying enzymes that promoteHIV-1 transcriptional silencing [49]. Thus, Ctip2-/- may beassociated with HIV-1 proliferation: a potential point ofrelationship between HIV-1 infection and disruption in toothdevelopment [48]. Although retroviruses do not interferewith the production of collagen I by odontoblasts inMoV13 mice, it does affect fibroblasts and other types ofcells [50].

With respect to tooth development and emergence, thereis some evidence to suggest that the use of antiretroviral

a consensus, and grouped orofacial manifestationsas: (1)those commonly associated with pediatricHIV infection; (2) those less commonly associatedwith pediatric HIV infection; and (3) thosestrongly associated with HIV infection but rarein children.

medication does delay dental development. One studyshowed that HIV positive children who were not on treat-ment presented practically no difference between the chro-nological age and dental age, while the children on antire-troviral treatment showed a difference of 10.67 months [51].This study built on evidence established by another studythat showed no significant difference between the chrono-logical age and the dental or the skeletal age of HIV-positiveand HIV-negative children over time; HIV-positive childrenpresented with delayed dental and bone development de-spite the administration of antiretroviral drugs [52].

Also, associated xerostomia with use of some antiretrovirals[53] and the high sugar content of HAART, formulated assweetened syrup or a suspension to make the drugs morepalatable for children [54], increases the risk of early childhoodcaries (Figs. 8 and 9). Since these drugs are taken continuouslyfor life, this further intensifies the caries risk for a child withHIV [55, 56]. An increase in caries prevalence has also beendirectly associated with a decrease in the absolute lymphocytecount of HIV-infected children [57••]. Some studies haveshown higher rates of caries and other oral diseases amongthose with HIV, while others have shown no difference or evenlower rates [7••, 58].

While there may not be a direct causative link between HIVand caries development, there is a symbiotic relationship for

risk and disease development. Untreated caries in primaryteeth has been clearly associated with pain, speech impedi-ment, difficulty eating, and being underweight. In HIV pa-tients, ECC may introduce infection into a compromisedimmune system and impact the ability to eat and maintainadequate nutrition. Compared with adults, the biologic mech-anisms of caries development differ in young children withnewly erupted teeth, continuous vertical and horizontal bacte-ria exposure, fragile tooth enamel, and immature immunesystems. In young children with HIV, transition from infectionto AIDS to death is compressed compared with adults [7••].Therefore, early detection and treatment are of particularimportance to maximize the quality of life and longevity ofchildren living with HIV. Because oral health disease and HIVare impacted by multiple and similar social, economic andbiological factors [8, 59], interventions for each disease mayhelp ameliorate both diseases.

Despite the potentially enhanced risk of hard and soft oraltissue diseases in HIV patients, findings reveal that a signif-icant number of patients who receive consistent medical

care for HIV do not receive adequate dental care [60]. Inaddition, over two-thirds of persons living with HIV dwellin developing nations where there is a notable shortage oforal health personnel and where medical treatment capacityis generally limited to pain relief or emergency care [61]. Infact, the dentist-to-population ratio in Africa is approximately1:150,000 compared with about 1:2,000 in most developedcountries [62].

Although many studies have shown HIV to have a neg-ative impact on oral health, this association has not goneunchallenged. However, in the absence of more conclusivedata and because of the disparate impact of disease on thepoor and underserved, an oral health protocol that factors inHIV status and assumptions of increased disease risk isadvised.

Oral Health Protocol for Children Living With HIV

Targeted, multi-faceted approaches to prevent, diagnose,and manage HIV and oral disease among children is essen-tial. Infants and young children are almost wholly dependenton their caregivers, and both diseases can be transferred tochildren through close maternal contact [63•]. While a com-prehensive care program for both caregiver and child is

optimal, offering such a program relies upon access to care,which varies by country and socioeconomic conditions. At aminimum, an oral health protocol starting at infancy shouldbe instituted for HIV-infected children. An infant oral carevisit (IOCV) is a simple, easily administered, and effectiveprotocol for use with HIV-infected children that includes 6simple steps: a caries risk assessment, proper positioning ofthe child in a knee-to-knee posture to actively engage thechild's caregiver, a toothbrush prophylaxis, a clinical dentalexam, fluoride varnish application, and the establishment ofself-management behavior goals utilizing motivationalinterviewing techniques [64].

IOCVs do not need to be conducted in a dental clinic norby a dentist. They only require a simple light source such asa flashlight, and 2 chairs and personnel with basic training tocomplete the 6 steps of IOCV. Primary care practitioners andothers who are trained to work with infants and children canand have been taught to perform oral health risk assessmentsto identify risk factors for dental caries and other oral healthissues. In fact, research has shown that these pediatric prac-titioners accurately identified children with dental carieswith good specificity (92 %–100 %) and sensitivity(87 %–99 %) after receiving only 1 2-hour training in infantoral health [65]. This makes IOCVs ideal for deployment inconditions with limited resources.

The first step of the IOCV focuses on Caries Managementby Risk Assessment (CAMBRA). Currently being validatedfor use among children, CAMBRA is an easy-to-use methodof assessing risk for ECC among children aged 0–5 [66••].After considering the many determinants of oral health,CAMBRA hones in on the core risk and protective factorsfor ECC in conjunction with the clinical findings to bestdetermine a child’s risk for ECC (Table 2). Risk factors andbiological predispositions include active decay in the mother orprimary caregiver in the past 12 months, bottle use, diet, andsaliva-reducing factors (e.g., HAART medications), develop-mental problems, and level of health literacy. Protective factorsinclude individual, family, and community features, such aswhether or not the child lives in a fluoridated community, if the

288 Curr HIV/AIDS Rep (2013) 10:283–293

child drinks fluoridated water, or whether the caregiver chewsproducts containing xylitol, which helps prevent ECC. Clinicalfactors include the presence of white spots and decay, restora-tions, plaque, inadequate saliva flow, and similarfactors—easily expanded to include the presence of oral le-sions. Depending upon the presence of these factors, a child israted to have low, moderate, or high risk for ECC. TheCAMBRA process assists the provider in explicitly consider-ing a child’s oral health condition and its relationship to HIVdisease indicators.

Positioning of the child is vital to ensuring that a child iscomfortable and cooperative as well as to enabling the exam-iner to clearly visualize the child’s oral cavity. Generally,infants and toddlers ages 6 months to 3 years, or up to age 5for children with special needs, should be placed in a knee-to-knee position. In this position, the examiner and the caregiversit facing each other, knee-to-knee. The child’s head lies in theexaminers lap with the child’s legs wrapped around the care-giver’s waist. The caregiver can then hold the child’s handsand stabilize the child’s legs and body with her arms. Childrenolder than 3 years can sit forward on their caregiver’s lap or sitalone in a chair. In this position, the examiner can now retractthe child’s lips and cheek to do a tooth brush prophylaxiswhile demonstrating the proper tooth-brushing technique tothe caregiver. The spongy handle of an age-appropriate sizedtoothbrush can be used to prop open the child’s mouth. This“Tell-Show-Do” encounter provides an opportunity to encour-age the caregiver to brush her own and her child’s teeth at leasttwice a day, especially before bed time, with fluoridatedtoothpaste. Children under the age of 2 should only use asmear of fluoridated toothpaste, while children over 2 shoulduse a small, pea-sized dab.

During the clinical examination, the examiner counts thechild’s teeth aloud, using the toothbrush handle as a mouthprop if necessary with the following information document-ed: visible plaque and location; chalky white spots; brownspots that indicate decay; tooth defects; deep pits/fissures;tooth anomalies; oral and other tooth abnormalities; missingand decayed teeth; existing restorations; untreated caries,and/or defective restorations; presence and location ofgingivitis; presence and location of soft tissue abnormali-ties; occlusal status; malocclusion or developmental pa-thology; and, indications of trauma. The provider shouldbe able to determine a caries risk level once theCAMBRA form and clinical exam is complete. Childrencategorized as moderate to high risk should be given afull-mouth topical fluoride varnish and be recommendedfor re-application every 3 months, and at a minimum ofevery 6 months, even if the child lives in a communitythat already receives the benefits of water fluoridation.

The sixth and final step of an IOCV should end on apositive note and proactively engage the caregiver and childinto making positive changes to improve their oral health. A

final discussion with the caregiver should include: results ofthe risk assessment interview and clinical exam; key mes-sages for good oral health (eat a healthy diet and limit thefrequency of sugary snacks and drinks); and a customizeddisease management plan or “care path” that includes treat-ment modalities and a recall frequency for follow-up aimedat reducing caries risk directly and other oral diseases indi-rectly [66••]. An effective care path helps to educate parentsabout healthy feeding habits, their own oral health risk, andwhat protective measures they can take to give their new-born a healthier start based on their current practices andability to take on new ones over time. The provider shouldalso establish a mutually-agreed upon self-management planwith the caregiver (self-management goals include providinghealthy snacks and brushing with fluoride to support positivebehavioral changes).

While the IOCVemphasizes screening children for caries,it also affords health care providers an opportunity to addressoral hygiene practices and techniques, dietary counseling, andoral health behaviors with the child's caregiver. These simplepractices are important for the oral health of children with HIVand can prevent their otherwise increased risk for caries andother oral health disease. With minimal startup and mainte-nance costs, IOCVs can improve oral health among HIV-infected children and can be applicable for children with highrisk for caries in the general population. For these children,IOCVs can provide the consistent disease management theymay not otherwise have access to by providing a lower cost,more accessible option in locations with limited resources.When more advanced services are required, personnel canrefer patients to trained dentists.

Discussion

The dental community has already recognized a need forconsensus guidelines for the dental treatment of personsliving with HIV and recommends the development of aspecialized oral health protocol for infants and young chil-dren with the disease [67]. Although definitive criteria canbe used to diagnose HIV, resource-poor countries often lackadequate laboratories and testing facilities to ensure earlydetection. Presumptive criteria incorporating the presence oforal soft tissue manifestations and lesions for the diagnosisof HIV in infected children have been widely documented[13, 68–70]. Oral lesions are among the earliest and mostcommon clinical signs of HIV [9], and can be used toascertain HAART efficacy [71]. For patients already onantiretrovirals, the presence of certain oral manifestationsmay suggest HIV progression and an increase in plasmaviral load. For example, oral manifestations such as oralhairy leukoplakia may suggest a failure in the current drugtherapy necessitating a change in the drug regimen [71].

In resource-limited countries, access and utilization ofdental services is inadequate. For the most part, even wheredental services are available, utilization is poor [72].Unfortunately, preventive and proactive early dental visitsare not perceived as a standard of care. Factors that impededental care services utilization in resource-limited settingsremain poorly understood. The main reason for dental ser-vice utilization and access continues to be for curativepurposes [73] with underutilization based on a lack ofperceived need for these services due to the absence of pain[10, 74]. Family structure also plays a crucial role in dentalservice utilization in these countries; those living with singlemothers or who had no parents would be less likely to utilizedental clinics [10, 75].

Empowering health care providers and families in all butespecially resource-limited settings to be able to early diag-nose, manage, and refer children with high risk for oraldiseases is very important, since obstetricians, physicians,nurses, and health care professionals are more likely to seenew mothers and infants than are dentists. Empowered withthis knowledge, they will be better prepared to make appro-priate decisions regarding timely and effective interventionsand to facilitate the establishment of dental homes for thesechildren. In the same vein, the majority of children with HIVwill be seen and managed by health care providers otherthan dentists. It is essential that providers be aware of theetiology and risk factors of ECC in a multidisciplinary andcollaborative approach. Empowering health care providersto use a simple risk assessment diagnostic tool likeCAMBRA will enhance the early diagnosis, managementand referral of children living with HIV for management oftheir oral health problems.

Conclusions

HIV-infected children are at higher risk for developing oralhealth diseases. Left undiagnosed and untreated, these dis-eases are likely to be deleterious to their long term healthoutcomes including HIV disease progression. Despite theirincreased risk and susceptibility, HIV-infected children arealso less likely to have access to dental care for prevention,early diagnosis, and treatment. In addition, although re-search is well established to address the oral health needsof adults living with HIV, established protocols remainnascent for pediatrics partially because of the differencesin the dentition and oral manifestations of young children.

Currently, there are interventions recommended by theAAP, the AAPD, the American Dental Association, and theAmerican Association of Public Health Dentistry. Theseinclude establishing a dental home and conducting a child’s

first dental visit by age 1 or within 6 months of the eruption ofa first tooth and a caries risk assessment [6•, 76•, 77•, 78, 79].Along with honing in on an effective assessment tool likeCAMBRA, it is important to find consensus on an oral healthprotocol to monitor the oral health of children infected withHIV. With consideration for regions impacted disproportion-ately by disease, this protocol must be comprehensive yetexecutable with limited resources and across a variety ofcultures. In the absence of more conclusive, consistent dataas to the increased risk for oral disease in HIV-patients, and inconsideration of the disproportionate burden of disease onunderserved populations, an oral health protocol that is basedon HIV status with assumptions of increased disease riskshould be used starting in infancy [80].
