Cleft lip and palate (CLP) is the most common congenital facial malformation and has a significant developmental, physical, and psychological impact on those with the deformity and their families. Risk factors contributing to CLP may conclude as genetic factors and environmental factors. The anatomical and morphological abnormalities related to CLP are favorable for dental plaque accumulation on the tooth surface. Therefore, patients with CLP undergo poorer oral hygiene and higher susceptibility to dental caries and periodontitis. In this review, we aim to conclude and update probable causes underlying the association between CLP and poor oral health and provide novel ideas of targeted early prevention for such oral diseases.
Introduction
During embryogenesis, oral and maxillofacial areas are developed from frontonasal process, the paired lateral and medial nasal processes, and the paired maxillary processes. Cleft lip (CL) and cleft palate (CP) are two kinds of congenital malformation resulting from unsuccessful embryonic facial fusion processes and usually co-occur in the form of complete unilateral (UCLP) or bilateral (BCLP) cleft lip and palate (1). Based on their association with specific malformative patterns or their presence as isolated defects, CL/P can be classified as syndromic (SCLP) and non-syndromic, respectively (NSCLP) (2). Cleft lip and palate (CLP) affects roughly 10 million people worldwide and reduces quality of life, especially children and adolescents (3). Risk factors for facial cleft can be classified into four categories: genetic factors, pharmaceutical and physical factors, maternal metabolic or nutritional imbalances, maternal infection or injury (4) (Figure 1).

Children born with head and jaw deformations that affect the development and function of teeth and jaws are generally more susceptible to poor oral health (5). Dental caries and periodontitis are two most common infection-driven diseases in oral cavity prevalent in individuals with poor oral hygiene habits. Although the etiologies of caries and periodontitis are reported independent, with dental decay induced by supragingival plaque while periodontal infections by subgingival plaque (6), disruption of dynamic ecologic equilibrium in oral microbial biofilms can both lead to the onset of these two inflammatory diseases (7). Biofilms on tooth surface will produce acids in the presence of dietary carbohydrates. These acids demineralize the enamel and eventually allow cariogenic bacteria to invade the enamel, dentin and even the pulp (8). Subgingival biofilm destruct the structural integrity of the junctional epithelium, consequently inducing inflammation and thus leading to pocket formation (9).
Cleft lip and palate affect not only patients' appearance, but also disrupts the continuity of maxillary arch, affects tooth structure, shape, number, eruption and maxillofacial growth. Due to the adverse change of the anatomical and morphological alterations, patients with CLP and alveolar cleft are more likely to accumulate dental plaque in oral cavity. Thus, studies have reported that those children presented a higher prevalence of extensive dental caries and periodontitis compared with general population (10–12). The objective of the review is to summarize and update the body of evidence on the causes underlying the association between CLP and poor oral hygiene.
Dental caries and periodontitis prevalence of children with CLP
Various epidemiological studies have demonstrated that there is an association between alveolar cleft and poorer oral health. A recent study found that among the children with cleft the prevalence of dental caries was found to be 71.9% (13). When comparing tooth caries and periodontal status, several studies showed that DMFT (Decayed, Missing, and Filled Teeth) and dmft scores were significantly higher in the control group without CLP, while plaque and gingiva indices such as plaque index and the gingival bleeding index were higher in CLP group than the controls (14–17). Different types of CLP seem to be quite diverged. Hazza'a et al. carried out a study and concluded that bilateral CLP experienced more dental caries than unilateral CLP patients, whereas only plaque accumulation was significantly higher in the BCLP patients (18). Howe et al. conducted a case-control study and recruited 3,326 patients with their relatives and confirmed the genetic factor is highly significant risk factor for children with CLP who are more susceptible to tooth decay (10). Evaluation of oral biofilm in children and adolescent revealed that the level of periodontal pathogens, including the most periodontopathic bacteria Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia, were statistically higher in the subgingival biofilms of the CLP group, thereby inducing more severe periodontitis (11, 19). Early-stage intervention such as early surgical repair is frequently performed within the first 1 to 2 years of life, which is of vital importance in team approach to cleft lip and palate (20). While fistulas following cleft palate repair may impair hygiene and occur in up to 35 percent of cases (21). Fritz et al. compared the oral health between patients with or without fistula after surgical correction of cleft palate and demonstrated a significantly lower oral health score in the fistula group, indicating poorer oral hygiene (22). Genes involved in the structure and development of congenital maxillofacial deformity may provide a basis for the link between CLP and dental caries. Mutations in EDARADD (ectodysplasin-A receptor-associated adapter protein) related with ectodermal dysplasia is likely to cause abnormal development of teeth, skin, hair, nails, and sweat glands (23). Therefore, the prevalence of dental caries was higher in syndromic cleft patients compared with those without a syndrome in northern Finland based on the outcomes of the current study (24).
Collectively, these studies allow us to confirm the hypothesis that children with cleft lip and palate have a significantly increased risk of dental caries and severe periodontal status as compared with the general population. Further in the text, we will explore the mechanisms that may contribute to such phenomenon (Figure 2).

Mechanisms linking dental caries and CLP
Tooth deformity
Children with oral clefts have a higher susceptibility for dental anomalies account for genetic and environmental factors. Numerous studies have demonstrated that dental anomalies are seen in a significant percentage of individuals with CLP (25–27). Cleft candidate genes such as MSX1, PAX9, IRF6, ANKS6 were confirmed associated with dental anomalies in individuals with CLP (28, 29). Methionine synthase gene responsible for methionine and homocysteine production may be associated with non-syndromic cleft lip and palate as well as dental caries (30). The structural deficiencies of embryonic development leads to microdontia, multiple missing teeth, ectopic teeth; supernumerary teeth; enamel and dentin malformation (27). Enamel hypoplasia often present with problems of discoloration and aesthetics, tooth sensitivity, reduced acid resistance, wear and erosion (31). Chapple et al. showed that developmental defects of enamel became more prevalent with age, with prevalence of 56% of 4-year-olds and 100% of 12-year-olds in patients with CLP (32). Kulas et al. carried out a case-control study and observed enamel color changes of permanent teeth three times more often in CLP children (33). While another research showed that there was no significant difference (P > 0.05) in the prevalence of development defects involving enamel among children with and without cleft (13). The rough surface attenuates acid resistant capacity of tooth and provides a critical niche for cariogenic bacteria to colonize. In addition, maxillary malformation, high incidence of supernumerary teeth and malposition of teeth result in crowding and dental malocclusion (34) which limits the use of toothbrush and antiseptic mouthwash and the natural cleaning of teeth by the tongue and saliva (35). Furthermore, tooth morphologic abnormalities like dens invaginatus also provide a favorable living environment for bacteria and fungi, which might be related to the pathogenesis and progression of dental caries (36, 37).
Cariogenic microbial dysbiosis
Orofacial cleft affects the structures and functions of oral cavities is closely related to potentially harmful changes in the composition and activities of the oral microbiota (referred to as oral microbiota dysbiosis) (38). Some studies have demonstrated the fact that children with cleft may exhibit higher level of Streptococcus mutans (S. mutans), Lactobacillus and Candida albicans (C. albicans) in their saliva (39–41), which are the most common cariogenic microorganisms (42, 43). In a study determined S. mutans and Lactobacilli prevalence in children with CLP, S. mutans was detected in the saliva of 45% of the children and Lactobacillus in 16% with S. mutans in 48% of the plaque samples and Lactobacilli in 8% (44). A more recent study has collated and analyzed microorganisms in saliva of 80 subjects with CLP and 144 subjects without CLP using checkerboard DNA-DNA hybridisation technique. Although no statistically significance in salivary microbial profile was observed between two groups, low level of species diversity could provide us with microbiota dysbiosis in oral cavities of children with CLP (45). Current mechanistic study in Irf6 cKO animal models confirm that caries incidence/severity and bacterial load was increased in gene knockout mice. They found the number of total bacterial and S. mutans colony forming units was significantly higher in Irf6 cKO mice compared with mice of wildtype (46). Lastly, Rawashdeh et al. detected colonization rate of Candida was higher in patients with cleft than that in control group (47). However, the high level of C. albicans colonization in oral cavities of CLP patients is often related to denture or orthodontic appliance wear, the association between C. albicans colonization and CLP itself needs to be further exploration (48).
Orthodontic treatments and appliance wear
Treatment of children and adolescents with CLP needs an organized team approach to provide optimal results. Orthodontic appliances have been linked to a higher caries experience (33). Fixed orthodontic appliances (FOAs) and dental prosthesis wear before or after surgical repair of CLP patients provides blind spots and reduces the effectiveness of saliva self-cleaning function (49). FOAs and denture base increases the area of plaque retention and makes it difficult for patients to maintain proper oral hygiene. The composition of dental plaque would change, leading to an increase in microbial population (50, 51), especially cariogenic bacteria Streptococcus and Lactobacillus which can lead to dental caries in the already susceptible mouths of individuals with CLP (52). van Loveren et al. carried out showed a comparative study and found that children performing early-stage preoperative orthopedics such as wearing acrylic plate in order to obturate the cleft were colonized earlier with S. mutans and Lactobacillus compared to non-plate oral cleft children. And the level of S. mutans increased with age (53). A meta-analysis that combined 39 studies oral prostheses such as dentures/palatal obturators and FOAs may directly affect the growth of Candida in the oral cavity (48). Additionally, patients wearing such devices are more likely to eat soft food in order not to destroy orthodontic appliances, which may lead to food particles accumulation over tooth surface, and increase the susceptibility of dental caries.
Mechanisms linking periodontitis and CLP
Alveolar bone deformity
Alveolar bone defect, maxillary deformity and deformed dental arch can always be seen in CLP patients (54). CLP defects disrupt the continuity of maxillary dental arch. Study found that poor oral hygiene was found in all CLP patients, while the periodontal disease of patients with cleft lip, palate and alveolar cleft were more severe and might underwent more periodontal tissue destruction compared to patients with cleft palate only (55, 56). Huynh-Ba et al. carried out a 25-year comparative study and concluded that alveolar cleft sites were likely to have more periodontal tissue destruction, patients with orofacial cleft had higher levels of plaque and tended to lose more periodontal attachment at cleft site (57). A related study with 75 complete unilateral CLP patients design showed increased plaque index of teeth in the cleft region compared with teeth on the contralateral non-cleft side (58). Nevertheless, some other studies observed no statistically significance between different type of cleft (11, 47, 59), which need further exploration for lager sample sizes. Additionally, due to vestibule malformation in some CLP patients, the oppression of gingiva near cleft sites may influence oral hygiene, then adversely exacerbate mucogingival and periodontal status at discontinuous dental arches (47).
Tooth deformity
CLP patients are born with a wide variety of dental anomalies, which could not only increase the susceptibility to dental caries, but also adversely affect periodontal status. Hypoplasia teeth were seen in 30.8% CLP subjects in a retrospective review (60). Crowded teeth favor the accumulation of dental plaque and make the removal difficult for CLP patients. In addition, dens invaginatus such as radicular lingual groove always found in maxillary lateral incisor has higher prevalence in patients with CLP (37), it creates a pathological dental pocket. Such a pocket resulted from an infolding of the enamel into dentine destroys the connection between periodontal tissue and cementum and allows bacteria propagate within, which can't be easily removed (26, 61, 62).
Periodontal microbial dysbiosis
Periodontitis is a multifactorial inflammatory disease caused by microorganisms accumulating in dental plaques below the gingiva (63) and the initiation of periodontal diseases can be primarily summed up as commensal oral microbial dysbiosis (64). In the current literature, CLP patients have been reported different in microorganism profile (65). Early studies identified Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans and Tannerella forsythia as causative agents in periodontal disease (66). Passinato et al. sampled dental plaque of individuals with or without CLP for subgingival microbiota analysis, they found higher level of those three periodontal pathogenic bacteria in the subgingival dental plaque of the CLP group, who underwent more severe gingivitis and periodontitis compared with control group (11). While Quirynene et al. did not find any significant differences of bacteria, neither in the proportion of aerobic and anaerobic bacteria among different sites (58). A more recent study described the subgingival microbial profile of children and adolescents with cleft and suggested higher relative proportion of Gram-negative anaerobic bacteria in teeth near the cleft compared with the control group (19). When comparing oral microbiota of infant with CLP and soft cleft palate (CSP), Machorowska et al. detected formation of the microbiota in individuals with CLP differed from that in CSP group, and the bacterial microenvironment was more pathogenic of patients with CLP, which is consistent with another comparative study of Tuna et al. (67). Such phenomenon could be explained by the communication between oral and nasal cavities and the transmission of bacteria from nasal cavity to oral cavity in CLP group (41).
When oral microbial dysbiosis takes place, pathogenic bacteria in oral cavity interacts with host immune system and induces inflammation and thus increases the risk of periodontal diseases. Taken as a whole, compared with individuals without CLP, periodonitits-related bacteria are more likely enriched in patients with CLP, which result in higher level of bacteremia and endotoxemia, consequently aggravating periodontitis.
Surgical and orthodontic treatments
Children affected by CLP need multidisciplinary care from birth to adulthood and treatment of children and adolescents with CLP needs an organized team approach to provide optimal results. The early-stage surgical repair of CLP is central to current CLP team-approached treatment. However, some related technologies are still in their infancy and need further improvement and optimization (68). Some postoperative complications such as hypoplastic maxilla, concaved mid-face, deformed dental arch and oronasal fistula are common and difficult to completely circumvent after surgery (54, 69). Oronasal fistula occurs because of the poor wound healing after surgical repair and the overall incidence varied greatly from 0 to 77.8% (21). Fistula may cause nasal air escape, difficulty with pronunciation, food or liquid regurgitation, all of which may lead to communication between nasal and oral cavities and require repair (70). However, Karim et al. obtained a lower fistula rate using a modified palatoplasty technique (71). Such complications are likely to affect oral hygiene, promote dental plaque adherence to the teeth and influence periodontal health due to the patient's difficulty in tooth brushing around the fistula site. In addition, residual scar tissues after surgical repair constantly pull on their surrounding gingiva and could result in gingival recession along with speaking and swallowing, and thus make it easier for plaque accumulation (72). Notably, besides surgical procedures, combination of preoperative and postoperative orthodontic treatment play an indispensable role in team-approached treatment of CLP (73). Excessive orthodontic force may induce localized inflammatory responses and exacerbate the loss of periodontal attachment (55).
Dental caries and periodontitis treatment effect of patients with CLP
Based on the ideas presented above, we can easily conclude that proper oral hygiene is difficult for many reasons, including anatomic factors, developmental factors, medical interventions, fear of pain, bleeding and soft tissue damage during toothbrushing near cleft site. Therefore, early dental interventions are necessary. Rivkin et al. found and stated that a regular brush may not be effective in the hygiene of the cleft area, the use of a small-sized toothbrush along with an interspace brush is efficient in some situations to improve oral hygiene of the patients with CLP mainly because the special toothbrush made it easier to reach interdental spaces (74).In other cases, selection of toothpastes, mouth rinses and use of fluoride products under the guidance of dentists could be helpful for improving oral hygiene (10, 75, 76). However, some studies found that there was no significant decrease of periodontal-related indices between CLP children with or without preventive dental care, suggesting nothing is more prior and effective than toothbrushing to remove dental plaque (77, 78). Novel biomaterials such as nanoparticulate cfDNA scavenger G3@SeHANs shows the therapeutic potential in periodontitis which is expected to be useful in CLP-related oral diseases and need to be further studied (79, 80).
Summary
Given that the present state of knowledge suggests that children with CLP may have a greater risk factor for poor oral health than the general population. Risk factors include those related to the cleft itself and/or some complications of secondary surgical repair.
In healthy state, there is a well-balanced equilibrium between bacteria and the host. Maxillary bone or tooth malformation, bad dietary habits, incorrected toothbrushing technique of CLP patients may result in destroying the equilibrium (81), thereby increasing the susceptibility to periodontitis and dental caries. Dental caries and periodontitis are driven by a variety of pathogenic microorganism (7). However, much current studies have been limited to several bacteria or fungi detection. Further studies need to be carried out to include more kinds of microbial and compare microbiota profile between patients with or without CLP, even between different types of clefts.
In summary, poor oral hygiene-related dental caries and periodontitis are unfavorable for oral function, aesthetics and self-confidence of CLP patients. Although rehabilitation and some quality of life (QOL) instruments is possible with good quality care (82), orofacial clefts inevitably impose a burden to the individual, the family, and society. Therefore, families with CLP children are likely to participate in and strictly adhere to more health care programs and related services (83). Under such circumstances, parents of children with CLP should raise their awareness of oral health and receive preventive dental care as early as possible, which may reduce the risk of dental caries and periodontitis in the future.
