Prevalence and risk indicators of gingival recessions in an Italian school of dentistry and dental hygiene: a cross-sectional study

Prevalence and risk indicators of buccal gingival recessions in a Moroccan periodontitis patients: A retrospective study

Background

This study investigates the prevalence, distribution and risk indicators of buccal gingival recessions (GRs) in periodontitis patients.

Methods

A retrospective examination of 400 periodontitis patients files was performed using an operating sheet. Univariate logistic regression analysis was performed to identify risk indicators of GRs. Multivariate regression analysis was conducted for selected variables with p < 0.05.

Results

354/400 (88.5 %) patients have at least one GR ≥ 1 mm. The prevalence of recession type (RT) at the patient level was 0.5 %, 2.25 % and 85.75 % for RT1, RT2 and RT3 respectively. Lower incisors are the most affected teeth (79.8 %). Upper canines present the lowest frequency (41.8 %). The univariate logistic regression showed that age (SE = 0.021; 95 % CI 1.01-1.10; p = 0.006), plaque index (SE = 0.50; 95 % CI 1.49-10.50; p = 0.006), level of plaque control (SE = 0.529; 95 % CI 0.90-0.72; p = 0.010) and periodontitis stage (SE = 0.41; 95 % CI 1.41-7.07; p = 0.005) were significantly associated with the presence of GR. In the multivariate regression model, significant results were confirmed only for age (SE = 0.021; 95 % CI 1.02-1.17; p = 0.006) and periodontitis stage (SE = 0.41; 95 % CI 1.35-6.75; p = 0.007).

Conclusion

The cross-sectional study showed a high prevalence of GRs. Lower incisors were the most affected teeth. Most patients have GRs with advanced interproximal attachment loss (RT3 GRs). Age, plaque index, level of plaque control and periodontitis stage resulted as risk indicators of GRs.

Evaluation of mid-buccal gingival recessions and occlusal interferences

BACKGROUND

Dental malocclusions may cause disruption in occlusal harmony, and destructive interferences during mandibular functional movements can be seen. Ideal occlusal contacts during dynamic mandibular movements may be crucial for preventing the occurrence of mid-buccal gingival recession (mbGR). While determining mbGR risk factors in young adults, the effect of occlusal interferences on mbGR has not yet been focused on. Based on this gap, this field needs to be clarified with new studies.

OBJECTIVE

The aim of this case-control study was to evaluate the relationships between the presence, extent and severity of mbGRs to dental malocclusions, occlusal interferences in anterior (AG) and lateral guidance (LG) and to determine the potential risk indicators in a young population.

METHODS

A total of 149 dental students were comprised and 70 of them presented mbGR(s) and 79 did not (18-25 years, 4553 teeth). Periodontal status was assessed with full mouth bleeding (FMBS) and plaque score (FMPS), probing depth, clinical attachment level, recession depth and keratinised tissue width (KTW) by a periodontist. Malocclusions and occlusal interferences were evaluated by an orthodontist. Logistic regression analyses provided data on the effect of occlusal interferences and the other indicators towards mbGR.

RESULTS

The mean of the number of teeth with mbGR(s) per subject was 4.3. The mean of the overall extent of teeth with mbGR(s) was 14.2%. FMBS, decreased KTW, self-reported bruxism, group function occlusion, increased contact number of all teeth and only premolars/molars in AG or LG and Class III malocclusions were significantly associated with the presence of mbGR. Decreased KTW presenting mbGR in the mandible and non-carious cervical lesion adjunct to mbGR significantly increased the odds of the severity of mbGR. Group function occlusion revealed higher mbGRs in premolar/molars than canine guided occlusion.

CONCLUSION

Increase in the occlusal interferences in premolars/molars during lateral and anterior guidance may have an effect on the presence and severity of mbGR. Further studies should be designed to confirm these findings.

Prevalance and clinical characteristics of gingival recession in Greek young adults: A cross-sectional study

OBJECTIVE

The current cross-sectional study aimed to investigate the prevalence of gingival recession (REC) in a sample of young individuals. In addition, the association with several risk factors was examined.

MATERIALS & METHODS

A 104 subjects, aged 18-30 years old, were randomly enrolled in the study. Participants were requested to fill in a simple structured questionnaire in order to provide information on dental hygiene habits, educational level, smoking and history of orthodontic treatment. Afterwards, all the included individuals were subjected to a thorough clinical periodontal examination including gingival recession (REC), gingival biotype, plaque levels and gingival bleeding index (GBI) assessment.

RESULTS

The mean prevalence of REC in the studied population surpassed 50% with an equal distribution among females and males. The most common teeth associated with REC were the lower left canine and left 1st premolar. Among the examined variables, only the bleeding index was found to be associated with the presence of REC.

CONCLUSIONS

Gingival recession was a prevalent condition among young individuals. Gingival inflammation was found to be the most significant factor affecting the incidence of REC.

Treatment of Gingival Recession: When and How?

Gingival recession is a common finding in daily clinical practice. Several issues may be associated with the apical shift of the gingival margin such as dentine hypersensitivity, root caries, non-carious cervical lesions (NCCLs), and compromised aesthetics. The first step in an effective management and prevention program is to identify susceptibility factors and modifiable conditions associated with gingival recession. Non-surgical treatment options for gingival recession defects include establishment of optimal plaque control, removal of overhanging subgingival restorations, behaviour change interventions, and use of desensitising agents. In cases where a surgical approach is indicated, coronally advanced flap and tunnelling procedures combined with a connective tissue graft are considered the most predictable treatment options for single and multiple recession defects. If there is a contraindication for harvesting a connective tissue graft from the palate or the patient wants to avoid a donor site surgery, adjunctive use of acellular dermal matrices, collagen matrices, and/or enamel matrix derivatives can be a valuable treatment alternative. For gingival recession defects associated with NCCLs a combined restorative-surgical approach can provide favourable clinical outcomes. If a patient refuses a surgical intervention or there are other contraindications for an invasive approach, gingival conditions should be maintained with preventive measures. This paper gives a concise review on when and how to treat gingival recession defects.
