Background: Constraints in dental access and limitations associated with service delivery necessitate the use of an appointment system in patient care. This research aimed to identify association between treatment appointments and oral health-related quality of life (OHRQOL) in dental patients at the Lagos State University Teaching Hospital.
Materials and Methods: This was a descriptive study that surveyed 412 individuals. Socio-demographic, clinical history, and OHRQOL data was collected using a structured interviewer administered questionnaire. Visual analog scale (VAS) was used to assess inconvenience while the oral health impact profile-14 was used for OHRQOL assessment at baseline and at review. Data entry and analysis was done using SPSS while ANOVA and Chi-square tests were used to determined significant association. P < 0.05 was considered significant.
Results: Most (175; 45.2%) dental appointments were within a month although 59 (15.2%) individuals had to wait for more than 6 months. Using VAS, 87 (22.5%) individuals were moderately inconvenienced while 68 (17.6%) were extremely inconvenienced. At baseline, the most commonly reported oral health quality of life impacts were within the dimensions “physical pain” and “psychological discomfort.” At review, there was increase in OHRQOL scores in the subdomains of pain (2.27 ± 1.80), self-consciousness (1.67 ± 1.15), discomfort on chewing (1.61 ± 1.13), and pronouncing words (1.49 ± 2.21). The highest mean impact score (2.27 ± 1.80) was observed in the subdomain of painful aching in the mouth.
Conclusion: Dental appointments appear to result in worse OHRQOL. Since the appointment systems in public oral health facilities may have a direct bearing on OHRQOL of patients, quality control standards on dental appointments should be established and enforced.

| Introduction|| |
Oral health is a state of being free from chronic orofacial pain, oral and pharyngeal cancer, and oral soft tissue lesion, birth defect such as cleft lip and palate, and disorders that affect oral dental and craniofacial tissues. Dental clinic attendance is positively related to quality of life, and pattern of regular dental visit at least once a year complements self-care in maintaining good oral health. Patients that visit the dentist regularly have oral diseases detected at an earlier stage, while avoidance of the dental clinic can result in untreated oral diseases and conditions, compromised health status, and even death. However, a lot of patients put off dental visits for reasons ranging from perceptions of need, lack of access, financial costs, and psychosocial factors such as dental anxiety.
The utilization of dental services is frequently driven by symptoms, often resulting in the need for curative care. In addition, many countries in Africa, Asia, and Latin America have an inadequate number of dental care professional, and the capacity of dental care services is generally restricted to emergency dental care and pain relief. Delayed treatment prevents people from achieving and maintaining good oral health, and it has implications for an individual's social and economic participation within society and may impact on their oral health-related quality of life (OHRQOL).,,
Over the last 30 years, the use of sociodental indicators in oral epidemiology has been widely advocated, because single measures of clinical disease do not document the full impact of oral disorders. The Oral Health Impact Profile (OHIP-14) is one of the most comprehensive instruments available for measuring OHRQOL. Oral disease and conditions can undermine self-image and self-esteem, discourage normal social interaction, and cause other health problems and lead to chronic stress and depression as well as incur great financial cost. They may also interfere with vital functions such as breathing, food selection eating, swallowing and speaking, and with activities of daily living such as work, school, and family interactions. Constraints in dental access and limitations associated with service delivery necessitates the use of an appointment system in patient care. This added delay in accessing care may be associated with heightened anxiety, inadequate pain relief, and heightened aesthetic concerns for patients with fractured or missing anterior teeth, prolonged taste impairment and unresolved speech difficulties. There is however a dearth of literature on the impact of dental appointment on the OHRQOL of patients.
This study thus aimed to determine if the OHRQOL in a group of dental patients at the Lagos State University Teaching Hospital (LASUTH) was worsened by dental appointment.
| Materials and Methods|| |
A descriptive study of dental patients at the LASUTH was conducted using an interviewer-administered questionnaire which was pretested. LASUTH is one of the tertiary health institutions located within Lagos State, and it is a referral center, meeting the health needs of most residents within Lagos and its environs.
The protocol for the study was submitted to the LASUTH Health Research and Ethics Committee and written approval was obtained (LREC. 06/10/854). Participation was voluntary, and the individuals were informed that they were free to decline to enlist and to withdraw from the study. Written informed consent was obtained from all the participants.
Using the prevalence of 31.24% for high level of inconvenience from a reference study, a sample size of 330 was determined. The sample was however increased to 412 by dividing the sample size by 0.8 to make provision for 20% attrition. The study population consisted of patients referred to the departments of preventive dentistry, restorative dentistry, oral and maxillofacial surgery and child dental health at the dental center. A systematic random sampling technique was done with initial categorization into four clinical departments and subsequent selection of respondents on each clinic day using the appointment register for each clinic day as the sampling frame. The sampling interval for each department (preventive dentistry: 3, restorative dentistry: 4, oral and maxillofacial surgery: 4, and child dental health: 3) was determined based on the number of patients booked on each day, and individuals were systematically selected using this interval as they received their appointment date.
Inclusion and exclusion criteria
Those included in the study were individuals who were 18 years or older that presented with a dental condition and were given an appointment for any routine dental procedure. Those excluded from the study were those that had tumors and severe maxillofacial injuries that would require general anesthesia, those that had a known anxiety disorder, patients with uncontrolled systemic comorbid conditions, and those that refused to give their informed consent.
Data collection and data collection tool
Data collection was done using a structured interviewer administered questionnaire by the researchers. The sample size was calculated using a formula for descriptive studies: N = Z pq/d2. Two interviewer-administered questionnaires were used for data collection. The first questionnaire was used at baseline when the individuals received their appointment after obtaining their informed consent, while the second one was administered on the treatment appointment day. The first questionnaire comprised of closed-ended question which obtained sociodemographic information; dental history and utilization of dental services by study participants; and the OHIP-14 section that measured OHRQOL. Sociodemographic information obtained included gender, age, marital status, education, occupation, and the income level of respondents. Dental history of the participants determined their pattern of attendance, reason for dental visit, and appointment duration. For each of the OHIP-14 questions in the OHIP segment, individuals rated how frequently they had experienced an impact in the preceding weeks, on a 5-point Likert scale with scores ranging from 0 to 4.
The second questionnaire determined the self-help practices the individuals resorted to while awaiting their appointment, reassessed their OHRQOL using the OHIP-14, and determined the level of inconvenience caused by the appointment using the visual analog scale (VAS). The 10-cm long line or VAS, which has a minimum score of 0 and a maximum score of 10, was used to determine the inconvenience the individuals experienced during the waiting time for the dental appointment.
Descriptive and inferential statistics were computed using SPSS (Statistical package for social sciences) for Windows (version 20, Chicago, IL, USA). Frequency distribution tables were generated for all variables, and measures of central tendency and dispersion were computed for numerical variables. Chi-square was used to determine the level of association between categorical variables while ANOVA was used to compare means. To calculate the OHIP-14 impact scores for individual domains, the individuals' individual domain scores was computed to give a maximum score of 4. For individual, subdomain scores 0, 1, and 2 were classified as low impact while scores 3 and 4 were classified as high impact. To calculate the overall OHIP-14 total impact score for all domains, item response codes were summed to give the final scores, with possible scores ranging from 0 to 56 which indicates the severity of OHRQOL impacts. The OHIP-14 final impact scores were classified as low (0–18.9), moderate (19–37.9), and high (38–56) to describe the impact level in the study population Differences and associations were considered statistically significant where the associated P ≤ 0.05.

Sociodemographic characteristics of the study population
Three hundred and eighty-seven individuals with mean age of 26.0 ± 7.5 and age range between 26 and 76 years who kept their treatment appointment were included in the final analysis. The highest percentage of individuals (100; 25.8%) were in the ≤20 years age category, and there were more females (221; 57.1%) enrolled in the study. The majority of participants (195; 50.4%) were married while 244 (63.0%) had tertiary education and 209 (54.0%) had never visited the dentist before [Table 1].

Reasons for treatment scheduled appointment
The highest percentage of individuals (29.5%) were scheduled for dental extraction, while root canal therapy was the least scheduled dental treatment (34; 8.8%) [Table 2].
Appointment duration and patients' self-care practices during waiting period
Majority (184; 47.5%) of individuals waited for an hour before being attended to while 4.4% had to wait for more than 5 h before being seen. The highest proportion (175; 45.2%) of the dental appointments were within a month although 15.2% had to wait for more than 6 months. During the waiting time, most (210; 54.3%) of the individuals did nothing, while others resorted to use of warm saline mouthwash (17.1%), self-medication (10.9%), and consultation of a chemist (8.5%) [Table 3].

How individuals felt when they were given an appointment
Using the VAS, with the score of 10 cm corresponding to being extremely inconvenienced, the mean VAS score was 5.95 ± 2.74 while the highest percentage of the respondents (87; 22.5%) were moderately inconvenienced while 68 (17.6%) were extremely inconvenienced [Table 4].
Oral health-related quality of life of the study participants at baseline
The highest OHRQOL scores were observed in the subdomains of pain (1.67 ± 0.42), discomfort on chewing (1.41 ± 0.11), self-consciousness (1.50 ± 0.12), and pronouncing words (1.25 ± 0.09). At least 77 (19.9%) of the individuals reported high impacts on their quality of life in these subdomains. The highest mean (standard deviation [SD]) impact score (1.67 ± 1.12) was observed in the subdomain of painful aching in the mouth. The least mean (SD) impact was recorded in the domain of total inability to function (0.77 ± 0.50) [Table 5].

Oral health-related quality of life of the study participants on the treatment appointment day
On the treatment appointment day, the highest mean impact score (2.27 ± 1.80) was observed in the subdomain of painful aching in the mouth. There was an increase in the OHIP-14 scores in all domains at the review, especially in painful aching of the mouth (0.60 ± 0.30). Eighty-nine (23%) of the individuals reported high impacts on their quality of life in these subdomains [Table 6].

Association between the oral health-related quality of life of the individuals on their appointment day and their sociodemographic variables
Association between the overall mean (SD) OHIP-14 scores and age group and occupation was statistically significant (P < 0.05). Individuals aged between 21 and 30 years (19.45 ± 10.3; P = 0.019*) and students (19.00 ± 9.5; P = 0.034*) had significantly higher mean (SD) impact scores. Association between the sociodemographic variables of the individuals and their mean (SD) OHIP-14 scores was however not significant in any of the other categories explored even though females (19.77 ± 11.4; P = 0.320), tertiary educated respondents (17.74 ± 10.2; P = 0.510), those that earned <20,000 naira monthly (18.60 ± 13.2; P = 0.100), and single respondents (19.72 ± 9.3; P = 0.631) had higher impact scores than their counterparts [Table 7].

Association between the oral health-related quality of life of the individuals on their appointment day and their clinical characteristics
Individuals who were scheduled for tooth extraction had higher overall mean (SD) OHIP-14 impact scores (20.29 ± 14.0) than individuals scheduled for other procedures. Similarly, individuals that waited for over 5 h (18.53 ± 14.8), those that had appointments longer than 6 months (19.17 ± 10.5), and those that resorted to self-medication (21.66 ± 12.2) also had higher mean impact scores than other individuals [Table 8].

| Discussion|| |
It has been observed that the greatest contribution of dentistry is in the improvement of quality of life because most oral diseases and their consequences interfere with, or have impacts on, daily life performances. There was a low level of attrition among the study participants possibly attributable to the low fees charged by the teaching hospital that has a subsidized payment plan and also to the central location of the hospital in Lagos Metropolis. The highest percentage of study participants were below 20 years of age, and this may not be surprising since about 66% of the participants were scheduled for procedures which are to mainly to treat the sequelae of dental caries (root canal therapy, extractions, and fillings). The highest demand for treatment for dental caries and orthodontic treatment is most common within this age bracket.
A history of dental visits based on symptoms is thus observed among majority of the individuals. More than half of the individuals had never had a dental visit and only a few had regular dental checkup. This was in agreement with other researchers that showed that despite the high need for dental treatment, dental service use continues to remain low and is often prompted by oral symptoms such as pain and the need for curative treatment. This indicates that there is a high level of unmet dental needs among the individuals and highlights the importance of preventive interventions and oral health promotion to reverse this pattern.
During the first visit, close to half of patients were seen within the 1st h that they arrived at the dental clinic though some had to wait for about 5 h before being attended to. Similarly, over 40% of the study participants were moderately to severely inconvenience by the duration of appointment that they were given. Nigeria has been identified as having a critical shortage of health care personnel, which is worse in the oral health sector, while the oral health facilities available are inadequate to meet the needs of the people., Limited access to oral health services is a factor that contributes to the high prevalence of oral diseases in Africa. Most public oral health facilities utilize appointment systems due to the volume of patients seen and also due to administrative inefficiencies in their systems. This limited access to oral health care in developing countries can be greatly improved by integrating oral health into the primary health care (PHC) system.
The study participants reported negative impacts on their OHRQOL in all subdomains at baseline. The highest mean impact score was observed in the subdomain of painful aching in the mouth. On the treatment appointment day, increases in all OHRQOL subdomains were observed, especially in that of painful aching in the mouth. The highest OHRQOL scores were observed in the subdomains of pain, discomfort on chewing, self-consciousness, and pronouncing words. More than 23% of the individuals reported high impacts on their quality of life in these subdomains. There was an increase in the overall and all sub-domain OHIP-14 scores in the individuals. The highest increase in the scores was observed in the subdomain of painful aching in the mouth. Toothache is frequently caused by dental caries and associated with poor oral health. Even though most dental diseases are not associated with mortality, they have an unfavorable consequence on usual social roles, self-esteem, nutrition, communication, interpersonal relations, employment, and general health.,, Delay in accessing dental treatment due to prolonged appointment may also further worsen a patient's OHRQOL while prompt dental treatment may help to restore physical and social function and self-esteem.
Respondents aged between 21 and 30 years and students had the highest mean impact scores. Some researchers have observed that young patients report the worst OHRQOL, especially those with low education. Conversely, another author reported worse OHRQOL in elderly patients with poor oral health, especially those that do not use dental services on a regular basis. In the present study, females reported more impacts on their OHRQOL than males as previously documented. Women care more about their health and their appearance and are also more communicative in relating their symptoms; this could explain the higher impact scores recorded by them.
Individuals who were scheduled for tooth extraction and fillings had statistically significantly higher overall mean OHIP-14 impact scores than patients on appointment for other types of treatment. Extraction and filling of teeth are the most common procedures performed in dental clinics, and it is mainly indicated for the painful sequelae of dental caries and periodontal disease. Individuals that required dentures fabrication also had high OHRQOL scores. Some researchers have observed that age, number of teeth, and cultural upbringing were important variables influencing OHRQOL. Other authors demonstrated a weak positive correlation between the number of missing teeth or denture wearing and OHRQOL.
Respondents that waited for over 5 h, those that had appointments longer than 6 months, and those that resorted to self-medication had higher mean impact scores than others. There is a threshold capacity in outpatient clinics where service supply equals demand, and an infinite queue is eventually formed when demand exceeds service supply. Gupta and Denton distinguished between a direct waiting time that the patient experiences while waiting in the clinic and an indirect waiting time which is the sequence between appointment booking and receiving treatment. These waiting times can have a direct bearing on the patient's quality of life as observed in this study. Evidence also shows that patients that are satisfied with dental treatment have positive experiences and tend to seek preventive dental care and hence have good oral health. In contrast, patients that have had negative experiences tend to avoid dental care.,
Our results have direct public health and service implications for oral health because most patients in Nigeria access oral health services from public facilities which utilize appointment systems to manage patient burden. Some of these facilities are however inefficiently managed due to infrastructural deficits and inadequate dental material supplies that result in prolonged and failed appointments. Since these deficiencies may have a direct bearing on OHRQOL of patients, it may be appropriate to ensure that quality control standards on dental appointments are established and enforced. This study however does not make conclusive causal inferences due to its descriptive nature but provides a basis for further exploratory studies.
| Conclusion|| |
The study participants reported negative impacts on their OHRQOL in all subdomains at baseline. On the treatment appointment day, increases in all OHRQOL subdomains were observed, especially in that of painful aching in the mouth. Individuals that waited for over 5 h, those that had appointments longer than 6 months, and those that resorted to self-medication had higher mean impact scores than others. Since the appointment systems in public oral health facilities are associated with some deficiencies that may have a direct bearing on OHRQOL of patients, it may be appropriate to ensure that quality control standards on dental appointments are established and enforced.
