Oral health status of pregnant women in Ilorin, Nigeria.

Oral diseases have been shown to negatively affect pregnancy outcomes, yet, routine oral health care is not a component of the antenatal care package in Nigeria. This study was designed to describe the pattern of the oral conditions in pregnancy compared to the non-pregnant controls. Two hundred and twenty-five pregnant women and 166 non-pregnant controls were studied from two healthcare facilities in Ilorin. Oral-related complaints were assessed in the pregnant population while both of the groups had an oral cavity examination. The mean age of the respondents was 28.24 years ±4.77 and 80% had at least a secondary school level of education. The prevalence of oral complaints among the pregnant women was 19.1%. Gingivitis was more common among the pregnant women than the non-pregnant women, and more demonstrable on examination. Oral healthcare should be a component of the antenatal care in our environment. Impact statement What is already known on this subject? Women experience oral disorders in pregnancy, which may be worsened by the physiological changes in pregnancy. What do the results of this study add? This study has demonstrated a higher prevalence of gingivitis in the pregnant women than in the non-pregnant women on oral examination. The signs of gingivitis were higher than its related complaints. What are the implications of these findings for clinical practice and/or further research? Therefore, dental care and an examination should be part of a routine antenatal care package to prevent the unwanted pregnancy outcomes that are related to oral disorders.

Distal cervical caries in second molars associated with impacted mandibular third molars: a case-control study.

OBJECTIVE: This study compares the incidence of cervical caries in the mandibular second molar associated with impacted third molar with that of fully erupted third molar. STUDY DESIGN: The participants consisted of subjects with second molar adjacent to an impacted third molar (study group), and subject with second molar adjacent to a fully erupted third molar (control group). Incidence of cervical caries on the second molar and other variables were recorded and analyzed for both groups. RESULTS: The incidence of distal cervical caries in the study group was 15.7% and no case of distal cervical caries was seen in the control (P = .000). DMF score in study group was significantly lower than in control (P = .000). The incidence of distal cervical caries increased with age of subjects and DMF scores (P ≤ .05). CONCLUSIONS: Distal cervical caries in second molars is a phenomenon limited only to impacted mandibular third molars.

Is healing outcome of 2 weeks intermaxillary fixation different from that of 4 to 6 weeks intermaxillary fixation in the treatment of mandibular fractures?

PURPOSE: This study was undertaken to compare the healing outcome of a short period (2 weeks) of intermaxillary fixation (IMF) with conventional (4-6 weeks) IMF in the management of fractures of the mandibular tooth-bearing area. MATERIALS AND METHODS: This was a randomized controlled study conducted at the Lagos University Teaching Hospital, Lagos, Nigeria, between November 2007 and January 2009. Subjects with minimally displaced mandibular fractures in the tooth-bearing area were randomly allocated into 2 treatment groups: IMF for 2 weeks (study group) or IMF for 4 to 6 weeks (control group). For the purpose of study analysis, the primary predictor variable was the treatment (IMF for 2 weeks vs IMF for 4-6 weeks). Other predictor variables were the age and gender of subjects. The primary healing outcome was considered either satisfactory or unsatisfactory. The following outcome variables that described the healing process were also compared in the 2 groups: healing time, postoperative infection, paresthesia, and maximal interincisal opening. Loss of body weight and oral hygiene status at the end of treatment were compared in the 2 groups. A value of P < .05 was considered significant. RESULTS: Satisfactory healing was observed in all cases in both groups. However, satisfactory healing was observed earlier (5.4 ± 0.9 weeks) in the control group than in patients with the short IMF period (7.2 ± 0.9 weeks) (P < .001). Malocclusion that was amenable to selective grinding was the only complication seen in both groups (n = 2 in study group and n = 1 in control group) (P = .492). Subjects in the control group lost more weight after treatment than those in the study group (P < .001). The recovery of interincisal mouth opening was also better in the study group than in the control group (P < .001). The study group had better oral hygiene than the control group at the end of treatment. CONCLUSIONS: The healing outcome was comparable in both groups. However, the healing time was significantly longer in the group with the short IMF period. The recovery of maximal mouth opening, oral hygiene status, and loss of weight body in the study group were significantly better than those in the control group. This study suggests that a short period (2 weeks) of IMF in the management of minimally displaced mandibular fractures of the tooth-bearing area in young adults is a suitable alternative to the conventional method in terms of the healing outcome.

Oral health-related quality of life following non-surgical (routine) tooth extraction: A pilot study.

AIM: The study was designed to explore the changes in oral health-related quality of life (QoL) in the immediate postoperative period following routine (non-surgical) dental extraction. SETTING AND DESIGN: A prospective study carried out at the Oral and Maxillofacial Surgery clinic of the Lagos University Teaching Hospital, Nigeria. MATERIALS AND METHODS: Subjects attending who required non-surgical removal of one or two teeth under local anesthesia were included in the study. A baseline QoL questionnaire (oral health impact profile-14 [OHIP-14]) was filled by each patient just before surgery, and only those who were considered to have their QoL "not affected" (total score 14 or less) were included in the study. After the extraction, each subject was given a modified form of "health related QoL" [OHIP-14]-instrument to be completed by the 3(rd) day-after surgery, and were given the opportunity to review the questionnaire on the 7(th) day postoperative review. RESULTS: Total OHIP-14 scores ranged between 14 and 48 (mean ± SD, 26.2 ± 8.3). Majority of the subjects (60%) reported, "a little affected." Only few subjects (5.8%) reported, "not at all affected," and about 32% reported, "quite a lot." Summation of OHIP-14 scores revealed that QoL was "affected" in 41 subjects (34.2%) and "not affected" in 79 subjects (65.8%). More than 30% of subjects reported that their ability to chew, ability to open the mouth and enjoyment of food were affected following tooth extraction. Few subjects (14-34%) reported deterioration in their speech and less than 20% of subjects reported that change in their appearance was "affected." Only few subjects (12.5-15.1%) reported sleep and duty impairment. Thirty-percent of subjects reported their inability to keep social activities, and 41% were not able to continue with their favorite sports and hobbies. Multiple regression analysis revealed no significant association between age, sex, indications for extraction, duration of extraction, intra-operative complications, and deterioration in QoL (P < 0.05). Consumption of analgesics beyond postoperative day 1 (POD1) was more common in subjects with socket healing complications than those without (P = 0.000). About 33% of subjects reported, "inability to work" (1-3 days). CONCLUSION: About a third of subjects experienced significant deterioration in QoL. The most affected domains were eating/diet variation and speech variation. Therefore, patients should be informed of possible deterioration in their QoL following non-surgical tooth extraction.
