Traumatic Tongue Laceration: An Experience of Two Tertiary Centers in South East Nigeria.

Background: Traumatic injuries to the orofacial region are common and can be challenging to the oral and maxillofacial surgeon. The tongue is one of the structures that can be involved; however, the incidence of this injury to the tongue appears rare. Most of the reported work on this topic is on children. Patients and Methods: This is a three-year prospective study of traumatic tongue lacerations managed at the oral and maxillofacial centers of two tertiary hospitals in the southeast of Nigeria. Result: A total of 37 cases with tongue lacerations among 353 patients with oral and maxillofacial trauma constituting a prevalence of 10.5%. Their age ranged from 6 months to 57 years with a mean of 18.4 years (standard deviation 17.5). Twenty three (62.2%) are males and 14 (37.8%) females in a ratio of 1.6:1. The duration of injury on presentation ranged from 45 minutes to 96 hours with a mean duration of 26.7 hours. Majority of the laceration occurred in the anterior part of the tongue (24) (64.9%). Thirteen falls (35.1%) and nine motor vehicle accidents (24.3%) were the most common etiology. Thirty six (97.3%) were sutured primarily on presentation while only one (2.7%) was delayed before closure. Anesthesia was achieved with only Local Anesthetic agent in 18 (48.6%) cases, whereas in 13 (35.1%) cases a combination of Local Anesthetic agent and sedation. Conclusion: Tongue lacerations are not very common in the southeast of Nigeria, and management in children may require sedation. Treatment could involve suturing the wound or being left alone to heal.

A comparative analysis of the level of cortisol and the number of teeth extracted among patients undergoing routine dental extraction.

BACKGROUND AND OBJECTIVE: A postextraction comparative (cohort) study was carried out to determine whether the number of teeth extracted has an effect on salivary cortisol and by extension on stress. SUBJECTS AND METHODS: Sixty-three consecutive patients comprising 27 males (42.9%) and 36 females (57.1%) with a male: female ratio of 1:1.3, divided into two groups of A and B with a mean age of 25.8 ± 4.9 years, and age range of 18-37 years took part in the study. Fifty (79.4%) of them in group A (22 males and 28 females) each had a tooth extracted while 13 (20.6%) in group B (5 males and 8 females) had two teeth removed. One ml of resting saliva was collected from each patient 10 minutes after the procedure and analyzed for cortisol. All extractions and sample collections were done between 10 am and 2 pm to standardize the study and control for the diurnal variation of cortisol. Statistical analysis of the generated data was performed by using Student's t-test on SPSS version 17.0. The level of significance was set at 0.05 with P< 0.05 regarded significant. RESULT: The result showed mean salivary cortisol level of 12.914 ± 2.4684 ng/ml for group A and 12.108 ± 1.7192 ng/ml for group B though not statistically significant (P > 0.05). Females had more extractions in the two groups when compared with males. Male gender had a statistical significance difference (P < 0.05). CONCLUSION: This study shows that the number of teeth extracted did not have effect on mean salivary cortisol, as a result two teeth extraction does not impart more stress to the patient when compared with one, and as such no additional adjuvant stress relieving measures are needed in two teeth extractions.

Evaluation of cortisol concentrations in saliva as a measure of stress in patients having routine dental extractions.

We measured changes in the salivary concentrations of cortisol as an index of stress, and to find out if patients were stressed during routine intra-alveolar dental extractions. A total of 126 patients (63 experimental and 63 controls) matched for age and sex with a mean (SD) age of 26 (5) years (range 18-40) were recruited. Samples of saliva from patients whose glands had not been stimulated were collected twice from the study group (30minutes before, and 10minutes after, the procedure) and once from the control subjects. All samples were collected between 10.00 and 14.00hours to standardise the method and control for the diurnal variation of cortisol. There was a slight but not significant increase in the mean salivary concentration of cortisol between the preoperative samples (mean (SD) 12.3 (1.5)ng/ml and the postoperative samples 12.8 (2.3)ng/ml in the study group) and the control 8.7 (1.0)ng/ml. However, there was no difference between the sexes. The study highlights a simple but effective way of evaluating stress in patients having intra-alveolar dental extraction, and emphasises the invaluable role of salivary cortisol in the evaluation of stress (particularly in our environment).

The delusion of halitosis: experience at an eastern Nigerian tertiary hospital.

BACKGROUND: Halitosis is a recognized problem in dental practice. Some individuals have the belief that they have offensive mouth odour which neither the dental clinician nor any other person can perceive. This condition is known as delusional halitosis. Delusional halitosis can be classified as either Pseudo halitosis or Halitophobia depending on the response to initial treatment. Halitophobia is an olfactory reference syndrome and is a psychological condition that the dental surgeon is ill equipped to treat alone. This study aimed to analyse patients diagnosed with delusional halitosis, highlight our experiences and make suggestions for improved management of such patients. METHODOLOGY: All patients who presented at the dental clinics of University of Nigeria Teaching Hospital between January 2005 and December 2009 with a primary complaint of oral malodour were examined organoleptically. Those with obvious halitosis and known psychological conditions were excluded from the study Once a diagnosis of delusional halitosis was made, each patient was educated on the nature of halitosis, its causes and prevention. They then received oral prophylaxis and oral hygiene instructions. They were then recalled at one week, four week and six week intervals to establish a definitive classification. RESULT: 18 out of the 25 patients who presented were diagnosed with delusional halitosis. 61% of them male and 39% of them female with an average age of 30yrs. Pseudo halitosis comprised a majority of the cases seen (13). Halitophobia was seen in the minority (5). Reasons sited for believing that they had mouth odour by the patients studied included, peoples reaction when they were in close proximity and how people tended to avoid them (94.4%), ability to self perceive the foul odour from their mouths (55%) and 27.8 % said they had been told by another person that they had bad breath. All the patients had very good oral hygiene, with a tendency to over indulge on oral care products and tended to use mouthwash, breath mints and sweets in an attempt to mask the perceived odour with a few having excessive tooth brushing habits. Most had visited 2 or more other physicians within the year of presentation at the clinic with the same complaint. The patients were embarrassed (55.6%) frustrated (27.6%), self conscious (11.1%) or felt helpless (5.6%) by their perceived foul mouth odour, but none claimed to have suicidal thoughts. CONCLUSION: In all cases of delusional halitosis, there is usually an underlying psychosomatic problem, which can range from an over valued belief to a frank delusional disorder where the individual can hardly be dissuaded from their belief of mouth odour. A multidisciplinary approach to treatment between the dental surgeons and the psychological specialists may present the best approach for the patients.
