Periodontal treatment needs and workforce requirements: comparisons between the normative and sociodental approaches using different skill mix models

Ab-Murat N, Sheiham A, Tsakos G, Watt R

Community Dent Oral Epidemiol, 2015 Apr;43(2):106-15.
PMID: 25178437 DOI: 10.1111/cdoe.12125

Assessment of dental treatment needs has predominantly been based on the normative approach, despite its numerous limitations. The sociodental approach is a more rational method of needs assessment as it incorporates broader concepts of health and needs and behavioural propensity. This study compares estimates of periodontal dental treatment needs and workforce requirements for different skill mixes using normative and sociodental approaches among a sample of adults in Malaysia.

Periodontal status (CPITN) of six-to fifteen-year-old west Malaysian aborigines (Proto-Malays)

PMID: 2621482

A survey of 303 six- to fifteen-year-old Proto-Malay children was carried out in Selangor, West Malaysia. The examinations were carried out using a chair-table and natural daylight. Periodontal status was assessed using the Community Periodontal Index of Treatment Needs (CPITN). The findings revealed a generally low prevalence of periodontal disease affecting only 25.08% of the sample examined. Of these, 15.72% were found to have a score of 1 (bleeding of the gingiva), while 9.36% had calculus on the tooth surface. In terms of treatment needs, 24.75% required dental health education. The relationship between these findings and the possible causes are discussed.

C-Reactive Protein Levels and Periodontal Diseases During Pregnancy in Malaysian Women

Ahmad A, Nazar Z, Swaminathan D

Oral Health Prev Dent, 2018 7 22;16(3):281-289.
PMID: 30027167 DOI: 10.3290/j.ohpd.a40759

PURPOSE: To investigate the association between plasma CRP levels and periodontal disease during pregnancy.
MATERIALS AND METHODS: Fifty-six pregnant women attending the Antenatal Clinic, UMMC for their first antenatal check-up consented and were recruited for this study: 28 subjects with diseased periodontium (test group) and 28 subjects with healthy periodontium (control). The test group underwent nonsurgical periodontal therapy and the control group was given oral hygiene education. Periodontal parameters and CRP levels were evaluated at baseline and 6 weeks. Pregnancy outcome data were recorded from the Antenatal Clinic, UMMC.
RESULTS: Plasma CRP levels in the test group were statistically significantly elevated compared to the control group (8.55 ± 5.28 mg/l vs 5.66 ± 2.91 mg/l). After nonsurgical periodontal therapy, a statistically significant reduction in the CRP level in the test group (2.06 mg/l) along with statistically significant improvement in periodontal status in both groups was observed. The mean birth weight for infants of both groups showed no statistically significant difference.
CONCLUSIONS: Plasma CRP levels in pregnant women with diseased periodontium were statistically significantly reduced after nonsurgical periodontal therapy. However, no association between CRP levels and adverse pregnancy outcome was observed.

Fulltext Mature Biofilm Degradation by Potential Probiotics: Aggregatibacter actinomycetemcomitans versus Lactobacillus spp

The biofilm degradation of Aggregatibacter actinomycetemcomitans is essential as a complete periodontal disease therapy, and here we show the effects of potential probiotic bacteria such as Lactobacillus spp. for the biofilm of several serotypes of A. actinomycetemcomitans strains. Eight of the 13 species showed the competent biofilm degradation of ≥ 90% reduction in biofilm values in A. actinomycetemcomitans Y4 (serotype b) as well as four of the seven species for the biofilm of A. actinomycetemcomitans OMZ 534 (serotype e). In contrast, the probiotic bacteria did not have a big impact for the degradation of A. actinomycetemcomitans SUNY 75 (serotype a) biofilm. The dispersed A. actinomycetemcomitans Y4 cells through the biofilm detachment were still viable and plausible factors for the biofilm degradation were not due to the lactic acid and low pH conditions. The three enzymes, protease, lipase, and amylase may be responsible for the biofilm degradation; in particular, lipase was the most effective enzyme for the biofilm degradation of A. actinomycetemcomitans Y4 along with the protease activity which should be also important for the other serotypes. Remarkable lipase enzyme activities were detected from some of the potential probiotics and a supporting result using a lipase inhibitor presented corroborating evidence that lipase activity is one of the contributing factors for biofilm degradation outside of the protease which is also another possible factor for the biofilm of the other serotype of A. actinomycetemcomitans strains. On the other hand, the biofilm of A. actinomycetemcomitans SUNY 75 (serotype a) was not powerfully degraded by the lipase enzyme because the lipase inhibitor was slightly functional for only two of potential probiotics.

PMID: 26982216 DOI: 10.1089/pho.2015.4076

The aim of this study was to assess the bactericidal efficacy of antimicrobial photodynamic dynamic therapy (aPDT) as an adjunct to scaling and root planing (SRP) against periodontal pathogens.

Moderate- to long-term periodontal outcomes of subjects failing to complete a course of periodontal therapy

Aust Dent J, 2017 Jun;62(2):152-160.
PMID: 27391220 DOI: 10.1111/adj.12440

BACKGROUND: The current retrospective cross-sectional study investigated 5-18-year treatment outcomes in subjects who did not complete a recommended course of periodontal therapy.
METHODS: Sixty-five subjects who voluntarily discontinued therapy were recalled. The subjects' demographic data and dental history since discontinuation of periodontal treatment were collected via questionnaires. The subjects' periodontal condition, radiographic data and individual tooth-based prognosis at pre-discontinuation and recall were compared.
RESULTS: A total of 229 teeth had been lost over time, mainly due to periodontal reasons. Upper and lower molars were most frequently lost. Rate of tooth loss (0.38/patient per year) was comparable to untreated patients. Deterioration in periodontal health in terms of increased percentage of sites with bleeding on probing (BOP) and sites with probing pocket depths (PPD) of 6 mm or more at re-examination was observed. Positive correlations were found between tooth loss and: (i) years since therapy discontinued; (ii) percentage of sites with PPD of 6 mm or more at pre-discontinuation; and (iii) at re-examination. Percentage of sites with PPD of 6 mm or more at recall was positively correlated with periodontal tooth loss and negatively correlated with percentage of sites without BOP.
CONCLUSIONS: Patients not completing a course of periodontal therapy are at risk of further tooth loss and deterioration in periodontal conditions over time.

Fulltext Effects of nonsurgical periodontal therapy on clinical response, microbiological profile, and glycemic control in Malaysian subjects with type 1 diabetes

The association between diabetes mellitus and chronic periodontal disease has long been established. Most of the researches linking these two very common chronic diseases were based on type 2 diabetes mellitus and chronic periodontal disease. However, this study was conducted to investigate the association between type 1 diabetes and chronic periodontal disease in Malaysian subjects. Forty-one Malaysian subjects, of which 20 subjects were type 1 diabetics and with chronic periodontal disease (test group) and 21 subjects with only chronic periodontal disease (control group), were included in the study. Periodontal parameters and plaque samples for microbiological evaluation were done at baseline, 2 and 3 months after nonsurgical periodontal therapy. Blood samples were taken from only the test group and evaluated for HbA1c at baseline and 3 months after periodontal therapy. There were no statistically significant difference in periodontal parameters between groups (P>0.05) and no significant improvement in the level of HbA1c in the test group. Microbiological studies indicated that there were significant reductions in the levels of the tested pathogens in both groups. The results of our study were similar to the findings of several other studies that had been done previously.
