  Abstract 


Introduction: Dental anxiety refers to a set of complex psychological issues bearing a significant impact in individual's lives reflecting in the form of dental visit avoidance, poor dental health status and decreases oral health related quality of life. Hence, it is imperative to consider those factors associated with dental anxiety so as to treat and promote better oral health. The review aimed to assess various factors associated with dental fear and anxiety. Materials and Methods: Literature search was done from Pubmed and Google scholar search engines to identify publications which explored factors associated with dental fear and anxiety. Results: Research evidence pointed a significant relationship of age, gender, maternal anxiety, previous dental experience, and number of siblings with dental fear and anxiety (DFA). Conclusion: Findings of the review clearly suggest that a better understanding of factors causing dental anxiety and phobia will help preventing dental avoidance and providing better care.

Keywords: Age, dental anxiety, dental fear, gender, maternal anxiety

  Introduction Top


Dental fear and anxiety (DFA) contribute significantly to the avoidance of dental care. Dental anxiety is referred to the anxiety related with thought of seeing a dentist for preventive or therapeutic procedures.[1] It has been stated as the fifth most prevalent reason for anxiety.[2] Anxiety is experienced even in daily activities like when making crucial decisions, exam time, in work place, entry to job market, etc., It is thus an emotional condition preceding the actual encounter that threatens a stimulus, which cannot even be identified sometimes.

A reaction evoked to a known stimuli or perceived threat is called fear, resulting in a fight or flight situation. Phobia on the other hand is continuous, non-realistic, and intense fear for a particular stimulus resulting in avoiding the perceived threat totally.[3] “Odontophobia” is the term described for irrational fear of dental treatment existing along with signs of terror, hypertension, trepidation, and unease as specified in the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV and the International Statistical Classification of Diseases and Related Health Problems (ICD)-10.[4]

Anxiety and fear are pretty much similar, formed by similar elements functioning in the same way. While emotions of anxiety are diffuse rather than specific as associated with fear and is witnessed in various situations and events. On the contrary, anxiety can be felt even when the feared stimulus is absent. DFA today is a significant issue in managing patients and these patients often delay or avoid in dental treatment seeking and turn down appointments. This in turn results in a vicious circle causing a higher prevalence and severity of dental disease co-found with delayed dental visits owing to DFA.

Severity of dental anxiety can be assessed using standardized questionnaires, of which dental anxiety scale is the most accepted and commonly used. Studies are conducted to assess various factors such as gender, age, education level, parental anxiety, and several others to bear an impact on fear and anxiety in dental patients.[5] While a study[6] found no differences in dental anxiety prevalence related to socio demographic factors in children, another study[7] reported no difference amongst gender in their study group. Hence the present review will be done to assess the impact of sociodemographic and environmental factors on dental fear and anxiety. Thus the review aimed to evaluate various socio demographic and environmental parameter influencing fear and anxiety in dental patients. Understanding fear and anxiety, and its factors helps the dentist to achieve patients' compliance and success in dental treatment.


  Methodology Top


Electronic searches, Literature search was done using databases of PUBMED/Medline and Google search databases. Only those studies assessing or exploring factors associated with dental anxiety were included. Terms used for the search was as per the MeSH; dental anxiety, fear, dental treatment, pain, patients. Data from dissertation work or unpublished data was not included for the review.

The institutional review board at the university approved the study and was in accordance with the ethical principles of the World Medical Association Declaration of Helsinki (2013). Selection criteria—Studies included in the review were descriptive studies, case control, prospective study and systematic reviews published between 2000 and 2020 assessing various parameters influencing fear and anxiety for dental treatment.

Data collection—The review author independently scanned the title, abstract, or both of every record retrieved in order to determine which study would be assessed further. All potentially relevant articles were considered as full text. If any discrepancy was noted, the study authors were mailed for clarification. An adapted PRISMA (Preferred Reporting Items for Systematic Reviews and Meta Analysis) flow chart is presented for study design [Figure 1].

Data extraction and management—Those studies which fulfilled the inclusion criteria, the author independently abstracted characteristics such as author, sample, and place of study, study design, prevalence and findings.

Outcome assessed: DFA associated with factors such as age, gender, education, parental influence (if patient is a child), previous dental experience, family structure.

Assessment of risk of bias in included studies—The author independently assessed risk of bias for each included study by employing the Cochrane's collaboration tool for assessment of risk of bias. Parameters for measuring risk assessment were research question, study population (demographics, location and period), groups recruited (eligibility criteria), sample size justification and outcome assessment. Only studies of moderate and high quality were included for the review.


  Results Top


A total of 13 studies were included in the review. Exploratory factors associated with dental anxiety were age, gender, previous dental visits, maternal/parental anxiety, family structure, and number of siblings.

10 out of 13 studies evaluated the role of gender in influencing DFA. 6 studies among them had reflected a significant relationship of gender with dental anxiety, while the rest 4 found no differences between gender and dental anxiety. 4 out of the 10 studies showing positive correlation of gender with DFA found that females were anxious than males. 7 studies analysed the effect of age with DFA, of which significant findings were found in 5 studies. It was found that as age advanced, the occurrence DFA decreased [Table 1].

5 studies tried to evaluate previous dental experience of study participants in influencing DFA, of which 3 studies reported a significant relationship. While 1 study specifically assessed DFA with severity and extent of dental caries and found no correlation between the same. Parental dental fear was a significant factor in increasing dental anxiety levels as seen in 3 studies. Family structure also is an important factor to be considered in DFA, with children of single parent exhibiting lesser anxiety levels than nuclear families children, as seen in a study [Table 1].


  Discussion Top


The review aimed to evaluate various sociodemographic and clinical factors associated with dental fear and anxiety in various groups. Anxiety poses grave repercussions when considering an individual's oral health and can become an important barrier to dental attendance resulting in poor attendance or dental avoidance. This in turn can result in poor oral health or the need for speciality dental care. DFA is also thought to influence quality of life with low oral health quality of life correlating to severe dental anxiety.[21],[22]

Age and gender was the most commonly evaluated factor in DFA and was also found to be significantly associated with anxiety, in all age groups. It was observed that younger age patients were more anxious than their older counterparts. This finding is in consensus with the belief that a child's cognitive capability grows with increasing age, thereby resulting in better awareness and understanding. Young children become anxious due to the feelings of unknown and of being abandoned.[23] Girls were generally more anxious than boys in the present review. These findings can be attributed to certain factors like the cultural setup of the sample being assessed, different scales used, willingness to accept their feelings and the real differences present between the genders.[24],[25]

More number of siblings bearing a significant impact on DFA could be due to their exposure to dental procedure during other sibling's therapy or them observing them displaying anxious behaviour while getting treated.[26]

Children whose parents are anxious to dental treatments either pass on this information to their wards or they see the feelings of anxiety which by all means get reflected with similar magnitude in development of dental anxiety.[25] But this feeling could get modified after the first dental visit, with the child's experience influencing and weighting the anxiety levels over his or her parent. Previous visits to the dentists significantly impacts anxiety levels by establishing a dentist—patient trust which matures and gets stronger with age. Hence, the review found that as age advanced, anxiety levels declined.

Speaking of pregnancy, dental phobia, lack of dental awareness, financial barriers, difficult access to dental service, misunderstandings/misconceptions about dental care during pregnancy, and low priority for oral health are some of the reasons for reduced utilization of oral care in pregnant women.[27] In a cross-sectional study, Modified Dental Anxiety Scale (MDAS) was used to assess dental anxiety and phobia among pregnant women visiting hospitals in Dhahran, Khobar, and Dammam in Saudi Arabia. The score of MDAS ranges from 5 to 25, and a cutoff value of 19 was used to identify participants with dental phobia. The study analyzed data of 825 participants, and the prevalence of dental phobia was appreciated in a considerable proportion. Having bad dental experience and being in first trimester of pregnancy were significantly associated with increased odds of dental phobia.[28]

Inspite of the significant associations found between many factors and DFA, it could possibly be that various etiological factors might have influenced the development of DFA. An individual might have had a bad past experience, which might have occurred in childhood and exhibits anxious traits. An interaction of all the factors cannot be overlooked. This concept is well summarised by Liddell and Locker in their statement “It is impossible to say from this study whether the experiences were, in fact, very traumatic, or whether the subjects were more sensitive to them”.[29]

The dental team play an important role in realizing the concept and factors associated with DFA as it affects dental health status, dental attendance, and also quality of life. First encounter of the patient is with the dental receptionist who must listen for emotional content as well as factual content—noticing rhythm, pitch, volume, and speed will give lots of information about this. Dental nurses or dental operators can help reassure anxious patients by reflecting empathy, having good listening skills and hold an ability to explain things to the patient in a comforting apprehensible language. This has the effect of “normalizing” their fear need.[30]

As a primary oral care physician, it is important to assess the coping of patient with adverse events, associated factors and motivational level to deal with the overcoming fear of dental treatment. This will eventually help the dental clinicians to develop a rapport with the patient, decide for coping strategies and use pharamacological interventions to ease the patient. Helping patients overcome dental or needle phobia is the most difficult of all and cannot be managed with traditional behavior shaping practices such as acclimatization, positive reinforcement, tell-show-do, or confidence building alone. Even cognitive behavioral therapy can only help the milder cases. Hypnosis or neurolinguistic programming skills are needed for the truly phobic.[30]

The dentist can even approach for psychiatric referral if suspects emotional psychiatric involvement in the patient.


  Conclusion Top


Understanding the magnitude of patient's fear in preventing dental visits and dental anxiety occurrence has direct implications in dental practice. Identifying the exploratory factors will enable the dentist to appropriately plan his/her treatment plan to reduce DFA which in turn reduces workplace stress.
